These devices combine modern technology and traditional agricultural knowledge, aiming to improve threshing efficiency, reduce labor input, and be able to adapt to different working environments and crop varieties.

[0003] Portable threshing devices need to move between different fields and detection points. Therefore, the volume and weight of the devices need to be as small as possible for easy carrying and storage. However, traditional wheels often occupy a certain space when not in use, which is not conducive to the carrying and storage of the devices. Content of the Utility Model

[0004] The purpose of the utility model is to provide a portable threshing device for on-site detection of rice to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, a portable threshing device for on-site detection of rice provided by the utility model includes a rice thresher. A fixed frame is installed on the outer wall of the rice thresher. A folding assembly is arranged inside the fixed frame. The folding assembly includes a plurality of connecting rods rotatably connected to the fixed frame. One end of each connecting rod is provided with a fixing plate. One end of the fixing plate is rotatably connected with a universal wheel. Two racks are slidably connected to the inner wall of the fixed frame. A gear meshing with the rack is connected to the outer wall of the connecting rod.

[0006] Furthermore, two guide rods are installed on the inner wall of the fixed frame. The rack is slidably connected to the outer wall of the guide rod.

[0007] Furthermore, two lead screws are rotatably connected to the inner wall of the fixed frame. The rack is threadedly connected to the outer wall of the lead screw. One end of the lead screw is connected with a worm. One end of the worm is rotatably connected to the fixed frame. A fixed rod is inserted into the fixed frame. Turbines meshing with the worm are installed at both ends of the fixed rod.

[0008] Furthermore, a pull rod is installed on the outer wall of the fixed rod. The pull rod is located outside the fixed frame. A grip is installed at the top of the pull rod. A finger groove is formed on the inner top wall of the grip.

[0009] Furthermore, an iron block is installed on the outer wall of the pull rod. A magnet magnetically attracting the iron block is slidably connected to the outer wall of the fixed frame.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0024] Embodiment 1:

[0025] Refer to Figures 1-4 , a portable threshing device for on-site detection of rice, including a rice thresher 1. A fixed frame 3 is fixedly installed on the outer wall of the rice thresher 1. A folding assembly 2 is arranged inside the fixed frame 3. The folding assembly 2 includes a plurality of connecting rods 201 rotatably connected to the fixed frame 3. One end of the connecting rod 201 extending outside the fixed frame 3 is fixedly installed with a fixing plate 202. A universal wheel 203 is rotatably connected to one end of the fixing plate 202 away from the connecting rod 201. Two racks 204 are slidably connected to the inner wall of the fixed frame 3. The outer wall of the connecting rod 201 is fixedly connected with a gear 205 meshed with the rack 204. The gear 205 is located inside the fixed frame 3.

[0026] The fixed frame 3 is used to fix and support the folding assembly 2. Moving the two racks 204 can make the plurality of gears 205 rotate. When the gear 205 rotates, it will drive the connecting rod 201 to rotate. The angle of the fixing plate 202 and the universal wheel 203 can be adjusted by using the rotating connecting rod 201. When it is necessary to move or carry the rice thresher 1, the fixing plate 202 and the universal wheel 203 can be adjusted to the vertical state, so that the universal wheel 203 contacts the ground. When it is necessary to store the rice thresher 1, the fixing plate 202 and the universal wheel 203 can be adjusted to the parallel state, so that the fixing plate 202 and the universal wheel 203 are retracted to both sides of the rice thresher 1, reducing the occupied space of the overall device and making the device more convenient for storage and carrying.

[0027] Refer to Figures 2-3 , two guide rods 4 are fixedly installed on the inner wall of the fixed frame 3. The rack 204 is slidably connected to the outer walls of the guide rods 4.

[0028] When the rack 204 moves, it slides along the outer walls of the guide rods 4. The guide rods 4 make the sliding of the rack 204 smoother. At the same time, the guide rods 4 also make the sliding of the rack 204 more stable and not prone to deviation.

[0029] Embodiment 2:

[0030] Refer to Figures 2-5, two screw rods 5 are rotatably connected to the inner wall of the fixed frame 3. The rack 204 is threadedly connected to the outer wall of the screw rod 5. One end of the screw rod 5 away from the fixed frame 3 is fixedly connected to a worm 6. One end of the worm 6 away from the screw rod 5 is rotatably connected to the inner wall of the fixed frame 3. A fixed rod 8 is inserted into the fixed frame 3. Turbines 7 meshing with the worm 6 are fixedly installed at both ends of the fixed rod 8.

[0031] Rotating the fixed rod 8 can drive the two turbines 7 to rotate. When the turbines 7 rotate, they will drive the worm 6 to rotate. The rotating worm 6 drives the screw rod 5 to rotate together. When the screw rod 5 rotates, the rack 204 will slide along the outer wall of the screw rod 5, achieving the effect of driving the two racks 204 to move simultaneously by rotating a single fixed rod 8, eliminating the need to individually adjust the movement of the two racks 204 and realizing the convenience of adjusting the angles of multiple fixing plates 202 and universal wheels 203.

[0032] Refer to Figure 2 and Figure 5 , a pull rod 9 is fixedly installed on the outer wall of the fixed rod 8. The pull rod 9 is located outside the fixed frame 3. A handle 10 is fixedly installed at the top of the pull rod 9. A thumb groove 11 is opened on the inner top wall of the handle 10.

[0033] When the fixing plate 202 and the universal wheel 203 are in a parallel state, the pull rod 9 and the handle 10 are in a vertical state. When it is necessary to move the rice thresher 1, pull the handle 10 to drive the pull rod 9 to tilt in the opposite direction of the rice thresher 1. Then, when the pull rod 9 is moved, it will drive the fixed rod 8 to rotate. After the fixing plate 202 and the universal wheel 203 are in a vertical state, the pull rod 9 also tilts to an appropriate angle. Then, the handle 10 can be pulled to drive the whole device to move. The thumb groove 11 provides a grip for the handle 10, enabling the operator to hold the handle 10 more stably.

[0034] Refer to Figure 5 , an iron block 13 is fixedly installed on the outer wall of the pull rod 9. A magnet 12 magnetically attracted to the iron block 13 is slidably connected to the outer wall of the fixed frame 3. The magnet 12 corresponds to the iron block 13.

[0035] When the pull rod 9 moves until the iron block 13 abuts against the magnet 12, it means that the fixing plate 202 and the universal wheel 203 are already in a vertical state. The magnet 12 and the iron block 13 are magnetically attracted to each other, which makes it difficult for them to separate after being attracted, and also prevents the pull rod 9 from easily rotating back to its original position during the movement of the rice thresher 1, causing the fixing plate 202 and the universal wheel 203 to be retracted to the parallel state.

[0036] Refer to Figure 5 , two sliding grooves 14 are opened on the outer wall of the fixed frame 3. Two sliders 15 are installed on the outer wall of the magnet 12. The sliders 15 are located inside the sliding grooves 14 and are slidably connected to the sliding grooves 14.

[0037] After the magnet 12 attracts the iron block 13, they are not easily separated. However, if the magnet 12 is moved along the outer wall of the iron block 13 and slides out, the magnet 12 and the iron block 13 can be separated. When the pull rod 9 needs to be rotated to a parallel state, the magnet 12 is moved along the outer wall of the iron block 13 and slides out. When the magnet 12 moves, the slider 15 will slide along the chute 14, thus realizing the movable effect of the magnet 12.

[0038] Working principle:

[0039] The fixed frame 3 is used to fix and support the folding assembly 2. By moving the two racks 204, the multiple gears 205 can be rotated. When the gears 205 rotate, they will drive the connecting rod 201 to rotate. By using the rotating connecting rod 201, the angles of the fixed plate 202 and the universal wheel 203 can be adjusted. When the rice thresher 1 needs to be moved or carried, the fixed plate 202 and the universal wheel 203 can be adjusted to the vertical state so that the universal wheel 203 touches the ground. When the rice thresher 1 needs to be stored, the fixed plate 202 and the universal wheel 203 can be adjusted to the parallel state so that the fixed plate 202 and the universal wheel 203 are retracted to both sides of the rice thresher 1, reducing the occupied space of the overall device and making it more convenient for the equipment to be stored and carried.

[0040] Rotating the fixed rod 8 can drive the two turbines 7 to rotate. When the turbines 7 rotate, they will drive the worm 6 to rotate. The rotating worm 6 drives the lead screw 5 to rotate together. When the lead screw 5 rotates, the rack 204 will slide along the outer wall of the lead screw 5, realizing the effect that rotating a single fixed rod 8 can drive the two racks 204 to move together at the same time, eliminating the need to individually adjust the movement of the two racks 204 and achieving the convenience of adjusting the angles of multiple fixed plates 202 and universal wheels 203.
