Description

Technical Field

[0001] This utility model relates to the field of agricultural crop transportation technology, specifically to an anti-clogging and cleaning structure for seed delivery pipes. Background Technology

[0002] In agricultural sowing, precise and efficient seed delivery is crucial. Traditional methods are prone to uneven sowing and low efficiency. Seed delivery tubes have emerged to address this issue, stably and accurately delivering seeds to designated locations, optimizing the sowing process, and laying a solid foundation for improving crop yield and quality.

[0003] Utility model patent CN211521013U discloses a seed loading device, which includes a conveying pipe, an auger rod installed inside the conveying pipe, and a motor installed on the conveying pipe. A support is provided on the conveying pipe. One end of the conveying pipe has a feed inlet, and the other end has a discharge outlet communicating with the conveying pipe. The motor is located between the support and the feed inlet. The output shaft of the motor faces the feed inlet and is coaxially connected to a transmission rod. The end of the transmission rod away from the motor is connected to the end of the auger rod via a linkage device. By placing the motor on the conveying pipe between the support and the feed inlet, the end of the conveying pipe near the feed inlet can be kept in a lower position by the weight of the motor. Rollers are provided at the lower end of the support, and a handle at one end of the conveying pipe facilitates movement of the device. Simultaneously, protective covers are provided on the outside of the linkage device and the transmission rod to prevent seeds from entering the pulley, reducing the impact on the linkage device. The protective covers also shield the transmission rod, preventing accidental injury to workers during motor rotation and improving the safety of the device.

[0004] When using traditional screw conveyors for seed transport, the screw conveyor often becomes clogged due to material buildup on the pipe walls when transporting small particles or seeds that are prone to sticking together. This causes the screw blades to jam, and if not cleaned in time, it will affect the continuity of the operation. However, traditional screw conveyors are difficult to disassemble and clean. Therefore, we propose an anti-clogging and cleaning structure for seed conveying pipes. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-7 This utility model provides a technical solution:

[0031] The anti-clogging and cleaning structure of the seed delivery pipe includes a delivery pipe body 1, which is a split design. The delivery pipe body 1 consists of a fixed lower pipe body 11 and a movable upper pipe body 12. A spiral blade 13 is coaxially sleeved between the fixed pipe body 11 and the movable pipe body 12. A support leg 111 is fixed to the bottom surface of the fixed pipe body 11, and a stop 112 is fixed to the bottom end of the fixed pipe body 11, which rests against the ground. With the support of the support leg 111, the delivery pipe body 1 can be tilted, thereby transporting seeds from a lower to a higher position. The bottom end of the support leg 111 is also equipped with rollers to facilitate the overall movement of the equipment, increasing the flexibility of the equipment.

[0032] In this embodiment, the spiral blade 13 is sleeved on the outside of the rotating shaft 131 and fixedly connected to the rotating shaft 131. The top end of the movable tube body 12 is fixed with an end plate 121, and the bottom end of the movable tube body 12 is fixed with a fixing seat 135. The first end of the rotating shaft 131 is rotatably connected to the end plate 121, and the last end of the rotating shaft 131 is rotatably connected to the fixing seat 135, so that the rotating shaft 131 is limited between the end plate 121 and the fixing seat 135, thereby limiting the spiral blade 13 within the movable tube body 12. A conveyor motor 132 is mounted on the rear surface of the fixed base 135. Pulleys 133 are mounted on the end of the output shaft of the conveyor motor 132 and the end of the rotating shaft 131. A belt 134 is sleeved between the two pulleys 133. When the conveyor motor 132 starts, the pulley 133 at the end of its output shaft drives the pulley 133 at the end of the rotating shaft 131 to rotate synchronously through the belt 134, forming a belt drive system. This achieves efficient power transmission from the conveyor motor 132 to the rotating shaft 131, causing the rotating shaft 131 to drive the spiral blades 13 to rotate inside the conveyor tube 1.

[0033] Specifically, a discharge hopper 115 is provided at the bottom of the top of the fixed tube body 11, and the discharge hopper 115 is connected to the interior of the conveying tube body 1. A feed hopper 122 is provided at the top of the bottom of the movable tube body 12, and the feed hopper 122 is connected to the interior of the conveying tube body 1. When the spiral blade 13 rotates in the forward direction, the spiral blade 13 will generate an axial thrust on the seeds inside the conveying tube body 1, so that the seeds can be transported from the feed hopper 122 to the discharge hopper 115, thus achieving the purpose of transporting seeds. At the same time, the gap between the outer edge of the spiral blade 13 and the inner wall of the conveying tube body 1 is ≤2mm to avoid particle retention during seed transport.

[0034] Furthermore, the fixed tube body 11 has a first protruding edge 113 on both long sides at the top end, and the movable tube body 12 has a second protruding edge 124 on both long sides at the bottom end. The first protruding edge 113 and the second protruding edge 124 are fixed together by bolts. The bolt connection design of the first protruding edge 113 and the second protruding edge 124 makes the inner walls of the fixed tube body 11 and the movable tube body 12 form a tight fit when closed, which not only ensures the sealing performance but also prevents seed leakage. At the same time, the bolt fixing method makes it easy to disassemble, so that the conveying tube body 1 can be separated.

[0035] In addition, several hinge seats 114 are fixed on the right side surface of the conveying tube 1, and several protruding rods 123 are fixed on the right side surface of the movable tube 12. The bottom end of the protruding rod 123 is inserted into the top end of the hinge seat 114 and forms a hinge. After the conveying tube 1 is separated, the conveying tube 1 can be quickly separated and the internal spiral blades 13 can be exposed by pushing the movable tube 12 upward, so as to clean the accumulated material on the tube wall and prevent the conveying tube 1 from being blocked when conveying seeds.

[0036] It is worth noting that a turning mechanism 2 is provided on the right side of the conveying tube 1. The turning mechanism 2 includes a base 21 fixedly connected to the fixed tube 11, a worm gear 22 rotatably mounted on the base 21, a worm 23 meshing with the worm gear 22, and a lever 24 coaxially connected to the worm gear 22.

[0037] Specifically, the base 21 is fixed on the abutment 112. The top of the base 21 has a top protrusion 211. A mounting groove for installing the worm gear 22 is opened on the right end face of the top protrusion 211. Support end seats with shaft holes are symmetrically arranged on the upper and lower sides of the right end face of the top protrusion 211. The two ends of the worm 23 are respectively inserted into the shaft holes of the corresponding support end seats and axially limited by snap rings. A lever 24 passes through the top of the hinge seat 114 and the bottom of the protrusion 123. The lever 24 is fixedly connected to the protrusion 123. A crank handle 231 is coaxially connected to the worm 23. When the crank handle 231 is cranked, the crank handle 231... The moving worm 23 rotates between the two support end seats, causing the worm wheel 22 to rotate in the meshing state. At this time, the worm wheel 22 drives the protruding rod 123 to move through the lever 24, thereby causing the protruding rod 123 to drive the movable tube body 12 to rotate around the axis of the lever 24, so that the movable tube body 12 separates from the fixed tube body 11. Since the spiral blade 13 is limited inside the movable tube body 12, the movable tube body 12 can drive the spiral blade 13 to move together when it separates from the fixed tube body 11, thereby exposing the spiral blade 13 so as to clean the seeds blocked in the conveying tube 1.

[0038] In addition, the crank handle 231 is coaxially fixed to the lower end of the worm gear 23. The minimum distance between the rotation trajectory of the end of the crank handle 231 and the base 21 is 5cm, so that when people crank the crank handle 231 by hand, the movement of their hands will not be blocked by the base 21, and the crank handle 231 can be cranked smoothly.

[0039] It is worth noting that the conveyor motor 132 involved in this utility model is a conventional technology and will not be described in detail here.

[0040] In this embodiment, the anti-clogging and cleaning structure of the seed delivery tube is used by first removing the bolts fixing the first protrusion 113 and the second protrusion 124, so that the fixed tube body 11 and the movable tube body 12 are separable. Then, the user holds and turns the crank handle 231, causing the crank handle 231 to drive the worm gear 23 to rotate on the base 21, so that the worm wheel 22 is driven to rotate by the worm gear 23 in the meshing state. Then, as the worm wheel 22 rotates, the worm wheel 22 drives the lever 24 to rotate together, so that the lever 24 drives the movable tube body 12 to rotate around the axis of the lever 24 through the protrusion 123, so that the movable tube body 12 separates from the fixed tube body 11. Since the spiral blade 13 is confined inside the movable tube body 12, the movable tube body 12 can drive the spiral blade 13 to move together when it separates from the fixed tube body 11, thereby exposing the spiral blade 13 so as to clean the seeds blocked in the delivery tube 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
