专利摘要:
A chopping apparatus, such as a harvester, comprises a grinding device for the sharpening of the blades of a chopping drum, in which a grindstone is guided over the width of the chopping drum and is advancable towards the drum. The grinding and advancing process can be performed automatically. A carrier (3), on which a fixed drag chain drive (11) and a grinding carriage (6) moveable in guide tracks (5, 5') are disposed, is journalled in the chopping drum frame (1) above and parallel to the chopping drum (2). Arranged on the grinding carriage (6) is a guide bracket (17), which encompasses the drag chain drive (11) and which moves the grinding carriage (6) to and fro through an entraining pin (18) disposed in the drag chain drive (11). In a reversal position of the entraining pin (18), a detent holder is acted upon by an abutment (20) through a pressure screw (23). A metal detent plate (36) moves a toothed wheel (31) firmly connected with a setting spindle (27) through one tooth and the carrier (3) is movable about its axis by a spindle nut (32) received in a setting arm of the central carrier (3). Thereby, the grindstones (10) received in a clamping frame (9) are vertically readjusted to the rotating chopping drum (2) after each double stroke of the grinding carriage (6) executed horizontally over the width of the chopping drum (2). <IMAGE>

for not adjusting the screw 27 outside the frame of the silo drum 1 with the handle 30 for instantly inserting the grinding stones 10 during the grinding and retraction process after grinding
8. The device according to PP. 1, 6 and 7, about t. characterized by the fact that the adjusting screw 27. between its collar 28 and the lock nuts 29 from one end is installed in the movable fitting part 26 fixed to the sleeve 25 located on the outer side of the frame of the silo drum 1, and from the other end is covered by the uterine nut 32 and mounted movably in the shoulder 33 of the Central rack 3,
9, The device according to claims 1, 6-8, characterized in that. That on the fitting part 26 of the sleeve 25 there is a safety sheet with a spring end 38 for engagement with the teeth of the ratchet wheel 31.
The invention relates to a tool for sharpening the blades of a silo drum to ensure high-quality cutting of the harvest mass.
From US Pat. No. 3677316, the movement of a cylindrical grinding stone from the hand is known. A rotating silo drum The ratchet wheel feeds a grinding stone mounted in a direction, and using a handle it can be moved along the length of the silage b Araban's knives, ..
The disadvantage of this device is low productivity, as the grinding stone is moved manually. In addition, safety precautions are provided for feeding and retraction of a grinding pit through a rotating silo drum,
In other known solutions, the grinding stone is supplied and retracted reliably with a screw, by means of which the grinding stone rotates around a hard, rotating,
However, in these devices, the automatic feeding of the grinding stone does not occur, and it is also not necessary to move it by hand through the silo drum,
In the well-known decision of the German Federal Law h &amp; The 22464О8 grinding disc is driven by an electric or hydraulic motor, and the grinding unit is suitable for grinding and sharpening knives. When the silo drum is standing, each knife is polished separately, and with the help of a tool, it is established a position between the knife and the grinding disc. In order to ensure that the silo drum rotates concentricly and the cutting knives are sharp, it is subsequently necessary to grind the grinding drum with another kind of grinding tool while rotating the silo drum .;
A disadvantage of the known device is a long sharpening time, for example for 6 knives about 120 minutes. Besides, ; It is necessary to move the grinding disc along the length of the knives with hand pulling device. The feeding takes place also by hand through a screw mechanism, with the grinding disc being fed in a straight line or around one point in the direction of the silo drum. The subsequent external grinding of the silo drum,
The decision on the GDR patent No. 111533 also does not exclude control over the feeding of grinding bodies and moving the grinding bodies along the length of the knives by hand. Using these tools to move the grinding wheels by electric current of grinding wheels, pumping of the knives is possible only in the workshop or near the mouth of the current source, since for grinding electric motors with voltages 110 V and more.
The purpose of the invention is to create a sharpening tool, which reduces the sharpening time of an axial drum knob, controls costs and increases safety measures, as well as using a drive source that is powered by the hydraulic system of the main machine, to provide a horizontal transverse movement , also automatic vertical feeding of grinding stones. The goal is achieved by the fact that the frame of the silo of the drum and parallel to the silo drum has a central pillar in which the drive sprocket is directly connected to the hydraulic motor, and the chain drive is retracted by means of a reversive chain color on the central rack console. . On the central rack there are guides along the entire length along which a grinding carriage moves on rollers that are adjusted by adjusting prisms. The grinding carriage has a chained guide linkage, which, with its slots, accepts a gripping bolt fixed in the chain drive, the Shlifov / Shnaka cart, which has a tensioning frame located opposite the guideband, for installing a number of sanding stones arranged next to it, fixed in chain drive and moving. with her bolt in a constant reciprocating. moving over a rotating for grinding, mainly in the reverse side of the silo drum. The vertical feed of the grinding stones, which are constantly moving back and forth with the grinding carriage, is due to the rotation of the entire central pillar in its bearings. When the reversing wheel is bolted on the grinding carriage, the bearing presses on the pressure bolt fixed in the rod on the inside of the frame of the silo drum and directed to the outside of the frame of the silo drum and connected to the gear holder lying on the side wall. The latch on the holder enters the teeth of the ratchet wheel mounted on the adjusting screw and is moved by means of a uterine nut, which is mounted on a lever rigidly fixed on the central rack and remake the central rack for the feed required for grinding around its axis. To ensure fast feed before and after the grinding process, as well as quick removal of the grinding &amp; stones back from the silo drum; a handle can be mounted on the adjusting screw, which allows the grinding device to move quickly outside the frame of the inclined drum. Against an undesired change in the position of the adjusting screw located on the outer side of the retaining sleeve and in the landing sleeve, an adjusting sheet is located on the landing sleeve, which can be pressed using a spring ring on the ratchet tooth. . The advantage of the proposed device lies in the fact that a complex assembly is formed due to the location of the grinding device and the drive on the vrashak cseysvatralchoy rack, which provides a stable position. Without shivering stones on the silage drum knives, this is the best grinding quality. The proposed device provides an automatic feed of grinding stones to the silo drum, as well as a drive and control of the grinding car on. central rack. No special drive source is required, since the hydraulic actuator associated with the transmission is driven by the hydraulic system of the main machine. Due to the speed-controlled movement of the grinding car with simultaneous feeding of grinding stones to the blades of the silo drum, a chain-guided drum is not required during the process of sharpening the worker, so that the risk of an accident during sharpening of the silo bar is eliminated. Automatic control of horizontal and vertical movements of the grinding stones, as well as the installation of some adjustable grinding stones in the grinding carriage, a stable position on the silo drum compared with the known grinding tools provides significant time savings, reducing maintenance costs during the grinding process and durability of grinding stones .
