    The invention relates to agriculture, in particular to landing gears.
    A known dredging and planting machine comprising a landing tool comprising a movable tubular element for forming a hole and feeding plants, a soil level sensor, equipped with a switch for generating a control signal, the soil level sensor being mounted on the tubular element, and an actuator for impact on landing gear
    The disadvantage of the known devices va - low productivity.
    The purpose of the invention is to increase productivity.
    This goal is achieved by the fact that the dredging and landing machine is additionally equipped with a second sensor for the surface of the surface of the soil and a second switch, with the second sensor mounted on the tubular element on the opposite side of its first sensor and the two mentioned switches in the operating position can close electrical circuit of the actuator. j FIG. 1 shows the proposed device, equipped with two sensors, with the landing device shown in the first, initial stage of work, a perspective view; in fig. 2 - measuring device for determining the level of the surface of the earth, installed. On the device and connected to the sensor, section; in fig. 3 adaptation at the second stage of work, when „the landing means is inserted into the ground at a predetermined depth; 4 shows a modified embodiment of the device.
    The device comprises a landing tool 1, which is rotatably mounted at one end to move up and down on the vehicle 2, the rotational movement of the landing tool is carried out using a hydraulic cylinder 3 located between the vehicle and the lifting bracket. The landing tool carries, at the free end of the lifting bracket, a movable tubular element 4, which is a hollow structure, and is positioned into the ground with the help of a lifting bracket to form a hole or groove in the ground. Between the lifting bracket and the movable tubular element there is a spring, working for stretching, trying to turn the said means into an inclined position forward / backward, in which it interacts with the stopper on the lifting
    - bracket. The planting tool interacts with a plant store (not shown) located on the vehicle, and from this store the plants can be
    About fed into the landing holes or furrows through the landing device. To measure the level of the ground in the selected landing site, sensor 5 and b are the levels of the soil surface.
    5 are disposed on each side of the landing gear in guides 7 and 8, which are rigidly fixed on it. Every sensitive agent
    0 (sensor) contains a rod located parallel to the landing gear and fitted at the upper end with protrusions 9 and 10, at the lower end - with stop plates 11 and 12,
    5 Compressors 13 and 14 are mounted between each anvil plate and the corresponding guide. These springs feed the sensor in the direction of its lower end position on the landing gear, in which each of the protrusions 9 and 10 is adjacent to the end of the respective guide. Measuring devices 15 and 16 rigidly
     mounted on the landing device above the corresponding sensor. Each measuring device includes a housing 17, a switch 18, and an actuator (pushing rod) 19 mounted
    0 is movable in the longitudinal direction parallel to the landing gear and protrudes outward from the bottom of the housing (Fig. 2). Compression spring 20 is installed between the lower surface of housing 17 and the flange on the lower end of the pushing rod. The switch contains a fixed and elastic contact strips 21 and 22, respectively, and electrically
    0 connected to a unit 23 equipped with a time relay for automatically controlling the points in time at which the plants must be unloaded and at which the hydraulic
    5 cylinder 3 will be launched (Fig. 1).
    The operation of the switch is carried out using an elastic contact strip 22 holding the switch open, and using
    0 of the actuator 19, which, when moving upward and in the housing under the action of the sensor, compresses the contact strips between them and closes the switch. When the switches are connected to the control unit, they can together close and break the circuit in the control unit.
    The device works as follows.
    While tractor 2, unsuitable landings, is moving continuously across the landing area, drive a tractor to explore the land for suitable landings. The landing gear is at this time held in a raised position above the ground using the lifting arm of the landing gear 1 and the hydraulic cylinder 3 (the landing gear is pulled forward without interference by the action of the spring 24 and abuts the stop lug 25). When the landing gear is located above the Corresponding landing pad, the driver actuates a hydraulic cylinder to stretch it, in the cut of which the landing gear is quickly lowered into the ground. When the landing gear has penetrated approximately 1/3 of the desired landing depth, the thrust plates 11 and 12 on the two sensors 5 and 6 come into contact with the ground. Upon further immersion of the landing gear into the ground, the sensors, remaining on the surface of the earth, move) (suts up to the appropriate height under the action of springs 13 and 14. Thus, the sensor moves the spring-loaded actuator 19 into the housing 17 upward in the direction of the measuring devices 15 and 16. This continues until technical support, until the two actuating rods engage with the corresponding contact strips 22 and press these strips against the contact strips 21 so that the current circuit in the control unit 23 closes. The control unit sends an electrical signal to the plant magazine and a control device (not shown), which is connected to the hydraulic cylinder and can be performed, for example, in the form of hydraulic or pneumatic magnetic solenoid claans. As soon as the hydraulic cylinder is released, the plant,
    unloaded from the plant shop and into the hole of the planting device. At this stage of the operation, the Pbsadge device has already penetrated to a predetermined depth into the ground and, as a result of moving the vehicle forward, turned in the required direction back / forward under the action of the spring 24
    remove from the bore
    or furrows. After planting the ground, it is tamped down with the help of a tamping device (not shown) mounted on the vehicle, then the landing and tamping device is retracted from the ground using a lifting bracket and a hydraulic cylinder (tamping down the ground and removing the tamping and carrier is also carried out when receiving a signal from control unit 23).
    If one of the protrusions of the sensor plates 11 and 12 hits a large stone, branch or some other obstacle on the ground (Fig. 3) when the landing device is inserted into the ground, the corresponding actuator 19 moves upward in its housing 17 and closes the switch 18 before than the landing gear penetrated the ground to the desired depth of landing. When this occurs, the control unit 23 does not start, since for this it is necessary that both switches be in the closed position at the same time. In-ground insertion of the landing gear continues until the second sensor is moved upward along the landing gear and its push rod closes the other switch. It can be assumed that another sensor will also be located on the stone while the landing gear is inserted into the ground between the indicated stones, however, the probability that this will happen is small.
    A more real case may be the case in which only one sensor is located above the stone (Fig. 3), while the other lies on clean ground and is displaced upward with the help of earth as the lower contact surface. At that moment, when both sensors are moved up and the corresponding switches are closed, the landing gear penetrates the ground at the required depth.
    The depth to which the landing gear penetrated the ground is shown by sensor 6, (FIG. 3, distance hg), while the other sensor 5 erroneously indicates the distance (FIG. 3, distance h).
    Due to the interaction described above between the penetration depth switches perceived by sensor 6, the actuation of the control unit is determined in such a way that the plants can be unloaded from the plant store and the hydraulic cylinder can be released.
    If the landing gear is inserted into the ground and tilted in the transverse direction relative to the vehicle, this causes further movement of the sensor, which determines when the landing will be carried out. In this way, the landing of plants to the required depth in the ground is provided ..
    The same happens when one sensor is located during planting over a relatively narrow MOU in the ground. In this case, the bottom of the slit is shown as ground level, as a result of which the plant will be planted to a lower depth, even when the planting device is inserted into the slit.
    Thus, two or more sensors in the device reduce the number of plants planted on Insufficient depth as a result of incorrect perception of its surface. The proposed device can be equipped with more than two sensors. The more sensors are provided, the less is the risk that all of them will be located above the stones, and then the landing device can freely enter the earth to the desired depth (the device’s reliability is sufficient if there are two sensors).
    In addition, the sensors can be located rotatable in the vertical direction.
    FIG. 4 shows two such sensors (26 and 27) and two measuring devices (16 and -16) of the previously described type. The sensors are rotatably mounted on each side of the movable tubular element 4 around the corresponding axis of rotation. (Fig. 4 shows the axis 28). A torsion spring (not shown) is installed between the respective pivot pins and the sensors, and tends to turn the sensor downward against the stop with the locking protrusion 29 mounted on the coupling device. The sensor is provided with an upper face cam e with a curved surface 30 against which the actuator 19 is pressed against the spring 20. In this embodiment of the device, the lower end of the pushing rod is rounded. The wheel can be freely attached to the free end of the sensor, although the presence of such a wheel is not necessary.
    When the assistive device is held in a raised position above the ground, the two sensors are pressed against the locking protrusions using torsion springs while the measuring device rod is on the lower profile surface of the cam curve 30. When the landing gear is inserted into the ground, the sensors contact the ground or an obstacle protruding above it and turning upward under the action of a spring force, the surface of the earth or the preparatory force being the lower support surface, as a result of which The cam curves are rotated such that the push rods are raised and lowered in the corresponding measuring devices. The insertion of the landing gear into the ground is carried out as described in the embodiments of FIG. 1-3, i.e. at the moment when the switches of the two measuring devices are closed by rods.
    In one variation of the device modification, the sensors may be mounted on a frame that is mounted on a vehicle (or a lifting bracket) located adjacent to the landing gear, but offset from it.
     It is also possible to arrange the measuring device and the control unit, so that the beginning of the working operation through the control unit is carried out with open circuits. The start-up control may be mechanical or electrical.
    In the proposed machine, devices for tamping the ground can be made, they are mounted on a vehicle or on a lifting bracket, or on a landing gear, and are operated by a control unit upon receiving a signal from the sensors.
    In another embodiment, the sensors installed with the possibility of displacement can be connected to a separate hydraulic cylinder, which is used as a means for ramming the earth.
