Description
Technical Field
[0001] This utility model relates to the field of silage processing technology, specifically to a discharge collection device for a silage chopper. Background Technology
[0002] Silage is a type of forage with a moisture content controlled between 55% and 65%, and a sugar content controlled between 1.0% and 1.5%. It can be mixed with the raw materials after cutting, allowing anaerobic bacteria to multiply and produce lactic acid, thus preventing and effectively inhibiting the further growth of putrefactive bacteria and mold.
[0003] To quickly refine silage, a chaff cutter is often used. The silage is fed into the machine through the trough, and then chopped by rapidly rotating blades. Under the influence of centrifugal force, the material is thrown out from the discharge structure for sorting. However, the discharge of such devices usually only has the ability to guide and store the material, and lacks a steering structure, making it difficult to adjust according to the collection direction and not easy to remove.
[0004] Now, a novel discharge collection device for a silage chopper is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a discharge collection device for a silage chopper to solve the problem of fixed discharge direction mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a discharge collection device for a silage chopper, comprising a connecting cylinder, a slot provided on the left side of the connecting cylinder, a base fixed to the top of the outer side of the connecting cylinder, and a rotating cylinder movably connected above the base, a corrugated pipe fixed to the top of the rotating cylinder, and a lifting cylinder fixed to the top of the corrugated pipe, a bracket fixed to the left side of the base, and a rotating handle movably connected above the front end of the bracket, a worm gear movably connected between the front and rear sides of the upper part of the bracket, and a worm wheel fixed around the lower circumference of the outer side of the rotating cylinder.
[0007] As a further technical solution of this utility model, the rear of the handle is fixedly connected to the worm, and the right side of the worm is meshed with the worm wheel.
[0008] As a further technical solution of this utility model, the rotating cylinder rotates horizontally at the top of the base, and the rotating cylinder and the outer worm gear are arranged in concentric circles.
[0009] As a further technical solution of this utility model, an inner cavity is longitudinally arranged at the center of the lifting cylinder, vertical grooves are longitudinally arranged on both sides of the lifting cylinder, support rods are fixed on the left and right sides of the top of the rotating cylinder, and screw holes are provided between the upper and lower ends of the front ends of the support rods. Bolts are threadedly connected to the lower sides of the front ends of the lifting cylinder, and the corrugated pipe is connected between the lifting cylinder and the rotating cylinder.
[0010] As a further technical solution of this utility model, the top end of the support rod is embedded in the vertical groove, and the rear of the bolt is embedded in the screw hole.
[0011] As a further technical solution of this utility model, the corrugated pipe extends and retracts with the movement of the lifting cylinder, and the corrugated pipe, the lifting cylinder and the rotating cylinder are arranged in concentric circles.
[0012] As a further technical solution of this utility model, a slot is provided at the rear of the lifting cylinder, and a net bag is fixed at the rear of the slot. A slot is provided above the slot, and a baffle is longitudinally movably inserted into the slot. Positioning holes are provided longitudinally on the interior of both sides of the baffle. Sleeve blocks are fixed on both sides of the top of the lifting cylinder, and pins are laterally movably inserted into the sleeve blocks.
[0013] As a further technical solution of this utility model, the side of the pin is embedded in the positioning hole, and the pin moves horizontally along the inner wall of the sleeve block.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the discharge collection device of the silage chopper not only realizes the adjustment of the orientation of the discharge port and the adjustment of the height of the discharge structure, but also realizes the adjustment of the size of the discharge trough.
[0015] By fixing a worm gear around the lower outer circumference of the rotating drum, the connecting cylinder is connected to the chaff cutter body through the slot on the left side. Then, hold the handle in front of the bracket and rotate the handle to guide the worm gear connected behind to mesh and push the worm wheel, so that the structure above the rotating drum rotates with the worm wheel. After adjusting the orientation of the discharge collection device, it is automatically locked to prevent the discharge collection device from rotating automatically.
[0016] By fixing a lifting cylinder to the top of the corrugated pipe, holding the lifting cylinder and adjusting the extension length of the corrugated pipe above the rotating cylinder, the support rods on both sides of the top of the rotating cylinder slide along the vertical groove inside the lifting cylinder. After aligning with the screw holes, the bolts are screwed in for reinforcement, which can prevent the lifting cylinder from sinking automatically and simultaneously adjust the height of the discharge collection structure, helping the device to spray grass into a limited space.
[0017] A baffle is inserted vertically into the slot, and a slot leading to the net bag is provided at the rear of the inner chamber of the lifting cylinder. The baffle can be pulled vertically in the slot above the slot to open it. After opening the baffle, its bottom is suspended above the slot. Align the positioning holes and sleeves on both sides, and push the pin horizontally so that the rod on the side of the pin is inserted into the positioning hole to prevent the baffle from drooping. This allows the hay to pass through the slot and enter the net bag. After finishing, close the baffle for storage. Attached Figure Description

[0025] The rear of the handle 15 is fixedly connected to the worm 14, and the right side of the worm 14 is meshed with the worm wheel 17. The rotating cylinder 4 rotates horizontally at the top of the base 3, and the rotating cylinder 4 and the outer circumference of the worm wheel 17 are arranged in concentric circles.
[0026] Specifically, such as Figure 1 and Figure 2 As shown, the connecting cylinder 1 is connected to the chaff cutter body through the slot 2 on the left side. Then, the handle 15 in front of the bracket 16 is held, and the worm gear 14 connected behind is guided to mesh and push the worm wheel 17 by rotating the handle 15. This causes the structure above the rotating cylinder 4 to rotate together with the worm wheel 17. After the orientation of the discharge collection device is adjusted, it is automatically locked.
[0027] An inner cavity 18 is longitudinally arranged at the center of the lifting cylinder 8. Vertical grooves 9 are longitudinally arranged on both sides of the lifting cylinder 8. Support rods 5 are fixed on the left and right sides of the top of the rotating cylinder 4, and screw holes 6 are provided between the upper and lower ends of the front ends of the support rods 5.

The baffle 10 can be pulled longitudinally in the slot 11 above the slot 12. After the baffle 10 is opened, its bottom is suspended at the top of the slot 11. Align the positioning holes 20 and the sleeve block 21 on both sides, and push the pin 22 horizontally so that the rod on the side of the pin 22 is inserted into the positioning hole 20 to prevent the baffle 10 from falling.
[0032] Working Principle: In use, the connecting cylinder 1 is first connected to the chaff cutter body via the slot 2 on the left side. Then, the handle 15 in front of the support 16 is grasped, and rotating the handle 15 guides the worm gear 14 connected behind it to engage and push the worm wheel 17, causing the structure above the rotating cylinder 4 to rotate along with the worm wheel 17. After adjusting the orientation of the discharge collection device, it automatically locks. Then, the lifting cylinder 8 is grasped, and the extension length of the bellows 7 is adjusted above the rotating cylinder 4. The support rods 5 on both sides of the top of the rotating cylinder 4 slide along the vertical groove 9 inside the lifting cylinder 8. After screwing in the screw hole 6, the bolt 19 is screwed in for reinforcement, which can prevent the lifting cylinder 8 from sinking automatically. The inner cavity 18 of the lifting cylinder 8 is provided with a slot 12 leading to the net bag 13. The baffle 10 can be pulled longitudinally in the slot 11 above the slot 12. After opening the baffle 10, its bottom is suspended at the top of the slot 11. Align the positioning holes 20 and the sleeve block 21 on both sides, and push the pin 22 horizontally so that the rod on the side of the pin 22 is inserted into the positioning hole 20 to prevent the baffle 10 from falling, so that the grass can pass through the slot 12 and enter the net bag 13. After finishing, close the baffle 10.
