Description

Technical Field

[0001] This utility model relates to the field of grass-hooking equipment technology, and in particular to an automatic grass-hooking device. Background Technology

[0002] In processing lines for tuberous and root crops (such as potatoes and sweet potatoes), hydraulic conveying is a crucial link connecting different stages. Crops are transported to the next processing stage via water flow in troughs. This method offers advantages such as stable transport and reduced crop damage. However, during harvesting and pre-processing, crops often contain a large amount of weeds, vines, and other debris. After entering the conveying troughs with the water flow, these debris can easily become entangled in equipment in subsequent stages, causing equipment jams and downtime. This not only affects production efficiency but may also increase production costs due to frequent repairs.

[0003] Traditional filtering and interception devices (such as grids) can initially block debris, but they are easily entangled and blocked by vines and long grass, requiring frequent manual cleaning and making them difficult to adapt to the needs of continuous production. Therefore, it is necessary to design an automatic grass-hooking device to solve the above problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0032] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides an automatic grass-hooking device, comprising:

[0034] The frame 10 is equipped with a grass-hooking mechanism. It should be noted that it can accurately hook weeds and other debris in the water tank, avoid debris from getting tangled or blocking the conveying channel, realize the full automation of the process from hooking to unloading, reduce the intensity of manual labor, and save labor costs.

[0035] The grass-hooking mechanism includes a power motor 1, a chain 2, a small sprocket 3, a large sprocket, a grass-hooking plate 7, a belt box 8, a slide 9, and a steel pipe 13;

[0036] Both the small sprocket 3 and the large sprocket are rotatably mounted on the frame 10. The belt box 8 is fixedly mounted on the frame 10. The output end of the power motor 1 is fixedly equipped with a power shaft. Both the power shaft and the large sprocket are fixedly equipped with pulleys. The pulleys are connected to a belt for transmission. Both the pulleys and the belt are located inside the belt box 8. It should be noted that there are two belt boxes 8, two sets of pulleys and belts, and two large sprockets. This allows the chain 2 to be transmitted normally.

[0037] Chain 2 meshes with small sprocket 3 and large sprocket. Hook plate 7 is rotatably mounted on the two chains 2. It should be noted that hook plate 7 is located at the center of water tank 5. During transmission, the collision amplitude between hook plate 7 and steel pipe 13 is small. The weeds thrown off will not fall into the chain 2, sprocket and other structures, and will not affect its normal transmission.

[0038] The steel pipe 13 is fixedly installed on the frame 10, and the slide 9 is provided with a disassembly and assembly mechanism. The slide 9 is connected to the frame 10 through the disassembly and assembly mechanism.

[0039] With the above structure, starting the power motor 1 causes the power shaft to rotate, which in turn causes the large sprocket to rotate through the pulley and belt. The large sprocket drives the chain 2 to move, causing the small sprocket 3 to rotate synchronously. The two chains 2 drive the grass-hooking plate 7 to move. The grass-hooking plate 7 can hook up the weeds in the water tank 5. Then the chain 2 slowly lifts the grass-hooking plate 7. When the grass-hooking plate 7 moves above the slide plate 9, it needs to collide with multiple steel pipes 13 in sequence, causing the grass-hooking plate 7 to shake and shake the hooked weeds onto the slide plate 9. The weeds fall through the inclined surface 6 on the slide plate 9, thus automatically performing grass-hooking processing.

[0040] Specifically, the assembly and disassembly mechanism includes a protrusion 11, a positioning element 12, a spring 14, a rope 15, a rope channel 16, a rotating shaft 17, and a sleeve plate 19. The protrusion 11 is fixedly installed on the slide plate 9. A groove is provided on the frame 10, and the protrusion 11 is engaged with the groove. The positioning element 12 is laterally slidably installed on the protrusion 11. The spring 14 is fixedly installed on the positioning element 12, and the positioning element 12 is engaged with the frame 10. The rope 15 is fixedly installed between the positioning element 12 and the sleeve plate 19. The rotating shaft 17 is rotatably installed on the slide plate 9, and the rotating shaft 17 is threadedly connected to the sleeve plate 19. The rope channel 16 is opened on the slide plate 9, and the rope 15 is in contact with the inner wall of the rope channel 16.

[0041] With the above structure, the surface of the slide 9 will get dirty after a long period of use. Rotating the shaft 17 can make the two sleeves 19 move towards each other, which in turn can make the sleeves 19 pull the rope 15, the rope 15 pull the positioning part 12, and the positioning part 12 squeezes the spring 14, causing the positioning part 12 to move out of the positioning groove. Then, pulling up the slide 9 can quickly remove the slide 9 for cleaning, which is convenient to use.

[0042] Specifically, a mounting frame 4 is fixedly installed on the frame 10, the power motor 1 is fixedly installed on the mounting frame 4, a water tank 5 is fixedly installed on the frame 10, an inclined surface 6 is provided on the slide 9, and there are multiple grass-hooking plates 7, with multiple hook grooves on the grass-hooking plates 7, which is to facilitate the cleaning and treatment of weeds.

[0043] Specifically, a hole is provided on the protrusion 11, the positioning element 12 is slidably installed in the hole, the spring 14 is fixedly connected to the inner wall of the hole, a positioning groove is provided on the side wall of the groove, the positioning element 12 is engaged with the positioning groove, a guide rod is fixedly installed in the hole, and the rope 15 is in contact with the outer side of the guide rod. It should be noted that the rope 15 can be guided.

[0044] Specifically, a guide plate 18 is fixedly installed on the slide plate 9, and a sleeve plate 19 is slidably sleeved on the outside of the guide plate 18. A bidirectional thread is opened on the outside of the rotating shaft 17, and a screw hole is opened on the side of the sleeve plate 19. The bidirectional thread is threadedly connected to the screw hole. It should be noted that this allows the sleeve plate 19 to move stably in the lateral direction, and when the rotating shaft 17 rotates, the two sleeve plates 19 can move towards each other.

[0045] Working principle:

[0046] S1: Start the power motor 1 installed on the mounting bracket 4 of the frame 10. The power shaft at the output end of the power motor 1 drives the pulley in the belt box 8 to rotate, which drives the large sprocket to rotate through the belt drive. The large sprocket and the small sprocket 3 are connected by the meshing of the chain 2. Therefore, the rotation of the large sprocket will drive the chain 2 to move in a cycle, and the small sprocket 3 will rotate synchronously to form a stable transmission system. Multiple grass hooks 7 between the two chains 2 move with the chains 2. When the grass hooks 7 move to the water tank 5 area, multiple hooks on their surface will insert into the water to grab weeds. As the chain 2 continues to drive, the grass hooks 7 are gradually lifted, bringing the weeds away from the water surface.

[0047] S2: When the hook plate 7 moves above the slide plate 9, it will collide with multiple steel pipes 13 on the frame 10 in sequence. The vibration generated by the collision causes the hook plate 7 to shake, shaking the weeds in the hook groove onto the slide plate 9. The weeds slide out along the inclined surface 6 of the slide plate 9, completing the automatic unloading process. The collision design of the steel pipes 13 ensures that the weeds are completely unloaded and prevents residue.

[0048] S3: The slide plate 9 is initially positioned by engaging the bottom protrusion 11 into the groove of the frame 10. The positioning element 12 inside the protrusion 11 pops out under the elastic force of the spring 14 and engages into the positioning groove on the side wall of the frame 10, thus fixing the slide plate 9. When the slide plate 9 needs to be cleaned, the rotating shaft 17 on the slide plate 9 is rotated. Since the rotating shaft 17 has a bidirectional thread on its outer side and is threadedly connected to the screw hole of the sleeve plate 19, and the sleeve plate 19 is slidably fitted on the guide plate 18, the rotation of the rotating shaft 17 will drive the two Each sleeve 19 moves towards the guide plate 18; the sleeve 19 pulls the connected rope 15, the rope 15 slides along the rope channel 16, causing the positioning element 12 to compress the spring 14 and retract into the hole of the protrusion 11, disengaging from the positioning groove; at this time, pull the slide plate 9 upward to remove the protrusion 11 from the groove, completing the disassembly of the slide plate 9. After cleaning, operate in the reverse order, release the rotating shaft 17, the spring 14 returns to its original position and pushes the positioning element 12 into the positioning groove, thus realizing the quick installation of the slide plate 9.

Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model.
