Description

Technical Field

[0001] This utility model relates to the technical field of foot-operated drum threshers, and in particular to a foot-operated drum thresher for threshing single rice plants. Background Technology

[0002] A foot-operated drum thresher mainly consists of a foot pedal drive, gear mechanism, drum, screen, and frame. It is suitable for areas without power or small-scale planting scenarios. The foot-operated drum thresher uses the up-and-down movement of the foot pedal to transmit power to the drum through the gear mechanism, causing the drum to rotate at high speed and separate the rice grains from the rice ears.

[0003] The gear mechanism on existing small foot-operated drum threshers is usually exposed. Impurities generated during rice threshing can easily adhere to the gear mechanism, leading to severe wear and tear and affecting the threshing effect. Utility Model Content

[0004] Therefore, it is necessary to provide a foot-operated drum thresher for single-plant rice threshing, which addresses the problem that impurities generated during rice threshing easily adhere to the gear mechanism, leading to severe wear of the gear mechanism.

[0005] The device includes a foot-operated threshing machine and a dustproof mechanism. The dustproof mechanism comprises a sealing frame fixedly connected to the front end of the foot-operated threshing machine. A rubber plate, an elastic plate, and a clamp are slidably connected to the inner wall of the sealing frame. The end of the elastic plate contacts the bottom of the sealing frame, and the surface of the clamp is engaged with the inner wall of the rubber plate. By clamping the clamp within the rubber plate, the rubber plate is locked within the sealing frame, thus providing dustproof protection for the gear assembly. The elastic plate seals the bottom of the sealing frame, preventing impurities from entering and ensuring effective dustproofing of the gear assembly, reducing wear between gears, and guaranteeing efficient rice threshing.

[0006] In one embodiment, a limiting block is fixedly connected to the top of the sealing frame, and the inner wall of the card holder is slidably connected to the surface of the limiting block.

[0007] In one embodiment, a pressure block is slidably connected to the inner wall of the limiting block, and the bottom of the pressure block contacts the top of the card holder.

[0008] In one embodiment, a spring and a rubber sleeve are fixedly connected to the end of the card holder, and the bottom ends of the spring and the rubber sleeve are fixedly connected to the top of the sealing frame. The spring is used to automatically move the card holder downward and lock it into the rubber plate, and the rubber sleeve is used to protect the spring and increase the resistance to the longitudinal movement of the card holder.

[0009] In one embodiment, a stop block is slidably connected to the inner wall of the limiting block, with one side of the stop block contacting one side of the pressing block. Through the cooperation of the stop block, the pressing block, and the limiting block, the card holder is locked, ensuring that the card holder is stably locked within the rubber plate. This, in turn, ensures that the rubber plate is stably locked within the sealing frame, guaranteeing dust protection for the gear assembly, reducing wear between gears, and ensuring effective threshing of rice.

[0010] In one embodiment, the surface of the spring is located inside the rubber sleeve.

[0011] In one embodiment, an anti-deviation groove is provided at the lower end of the inner wall of the sealing frame, and the surface of the elastic plate is slidably connected to the inner wall of the anti-deviation groove. The anti-deviation groove is used to limit the movement of the elastic plate, preventing the elastic plate from dislodging from the sealing frame during gear transmission, thus ensuring the dustproof effect on the gear device.

[0012] In one embodiment, a nylon rope is fixedly connected to the front end of the abutment, and the other end of the nylon rope is fixedly connected to the front end of the limiting block. The nylon rope is used to limit the placement range of the abutment, preventing the abutment from completely detaching from the limiting block, thereby avoiding the risk of the abutment being lost.

[0013] Beneficial effects

[0014] 1. By clamping the rubber plate inside the bracket, the rubber plate is locked inside the sealing frame, thereby achieving dust protection for the gear device. The elastic plate is used to seal the bottom of the sealing frame, preventing impurities from entering the sealing frame, ensuring the dust protection effect of the gear device, reducing wear between gears, and ensuring the threshing effect of rice.

[0015] 2. By using the cooperation of the abutment block, the pressing block and the limiting block, the card holder is locked, ensuring that the card holder is stably locked in the rubber plate, which in turn ensures that the rubber plate is stably locked in the sealing frame, ensuring the dustproof effect of the gear device, reducing the wear between the gear devices, and ensuring the threshing effect of rice.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. 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.

[0025] The following is combined Figures 1-5 This invention describes a foot-operated drum thresher for threshing single rice plants.

[0026] In one embodiment, a foot-operated drum thresher for single-plant rice threshing includes: a foot-operated thresher 100; and a dustproof mechanism 200. The dustproof mechanism 200 includes a sealing frame 201 fixedly connected to the front end of the foot-operated thresher 100. A rubber plate 202, an elastic plate 203, and a clamping bracket 204 are slidably connected to the inner wall of the sealing frame 201. The end of the elastic plate 203 contacts the bottom of the sealing frame 201, and the surface of the clamping bracket 204 is clamped to the inner wall of the rubber plate 202.

[0027] It should be noted that the brand of the foot-operated threshing machine 100 is Xipeng, and the product number is 10112032022446.

[0028] The foot-operated threshing machine 100 is typically composed of a drum and a casing. The rear end of the sealing frame 201 is fixedly connected to the front end of the casing. The surface of the drum is rotatably connected to the inner wall of the casing. A first gear is fixedly connected to one end of the drum. A second gear is meshed with the surface of the first gear. Both the first gear and the second gear are rotatably connected to the inner wall of the sealing frame 201. A pull plate is hinged to the front end of the second gear. The surface of the pull plate is slidably connected to the inner wall of the elastic plate 203. A pedal frame is hinged to the lower end of the inner wall of the pull plate. The surface of the pedal frame is hinged to the lower end of the inner wall of the foot-operated threshing machine 100.

[0029] In this embodiment, before threshing the rice, the clamp 204 is pulled upwards away from the rubber plate 202, releasing the rubber plate 202 from its locking position within the sealing frame 201. The rubber plate 202 is then pulled laterally within the sealing frame 201, opening the front end of the sealing frame 201. Lubricating oil is applied to the first and second gears inside the sealing frame 201. The rubber plate 202 is then pushed laterally to a suitable position within the sealing frame 201, pushing the clamp 204 downwards within the sealing frame 201 and locking it inside the rubber plate 202. This locks the rubber plate 202 within the sealing frame 201, sealing the front end of the sealing frame 201 and protecting the first and second gears. The sealing frame 201, rubber plate 202, and elastic plate 203 are used to prevent impurities from adhering to the first and second gears, reducing wear on the first and second gears.

[0030] The operator stands beside the foot-operated thresher 100 and slowly and evenly feeds the prepared single rice plants or small bunches of rice into the feed inlet between the drum and the screen. The operator steps on the pedal frame with one foot, applying even rhythm and force. The pedal frame moves, pulling the pull plate. The moving pull plate causes the elastic plate 203 to move within the sealing frame 201, rotating the second gear. The moving elastic plate 203 blocks the bottom of the sealing frame 201. Because the diameter of the second gear is larger than that of the first gear (the specific gear diameter ratio can be selected according to actual needs), the rotation of the second gear drives the first gear to rotate rapidly. The rapid rotation of the first gear drives the drum to rotate rapidly. During rotation, the threshing elements on the drum collide, rub, and knead with the rice plants, separating the rice grains from the ears. The separated rice grains fall onto the inner bottom wall of the foot-operated thresher 100. At this time, the operator places rice straw and other impurities next to the foot-operated thresher 100.

[0031] like Figure 5As shown, a limiting block 206 is fixedly connected to the top of the sealing frame 201. The inner wall of the card holder 204 is slidably connected to the surface of the limiting block 206. A pressure block 205 is slidably connected to the inner wall of the limiting block 206. The bottom of the pressure block 205 contacts the top of the card holder 204. A spring 208 and a rubber sleeve 209 are fixedly connected to the end of the card holder 204. The bottom ends of the spring 208 and the rubber sleeve 209 are fixedly connected to the top of the sealing frame 201. A stop block 207 is slidably connected to the inner wall of the limiting block 206. One side of the stop block 207 contacts one side of the pressure block 205. The surface of the spring 208 is located inside the rubber sleeve 209. A nylon rope 210 is fixedly connected to the front end of the stop block 207. The other end of the nylon rope 210 is fixedly connected to the front end of the limiting block 206.

[0032] In this embodiment, the restriction on the card holder 204 is loosened, and the elastic force of the spring 208 pushes the card holder 204 downward on the surface of the limiting block 206 and within the sealing frame 201, so that the card holder 204 is locked in the rubber plate 202, pushing the pressure block 205 to move laterally within the limiting block 206, so that the bottom of the pressure block 205 abuts against the top of the card holder 204, and the abutment block 207 slides into the limiting block 206, so that one side of the abutment block 207 abuts against one side of the pressure block 205, thereby locking the card holder 204.

[0033] like Figure 4 As shown, the lower end of the inner wall of the sealing frame 201 is provided with an anti-deviation groove 211, and the surface of the elastic plate 203 is slidably connected to the inner wall of the anti-deviation groove 211.

[0034] Working principle: Lubricating oil is applied to the first and second gears inside the sealing frame 201. The rubber plate 202 is pushed to move laterally to a suitable position within the sealing frame 201, loosening the restriction on the card holder 204. The elastic force of the spring 208 pushes the card holder 204 downward on the surface of the limiting block 206 and within the sealing frame 201, causing the card holder 204 to be locked inside the rubber plate 202. The pressure block 205 is pushed to move laterally within the limiting block 206, causing the bottom of the pressure block 205 to abut against the top of the card holder 204. The abutment 207 is slid into the limiting block 206, causing one side of the abutment 207 to abut against one side of the pressure block 205, thereby locking the card holder 204 and locking the rubber plate 202 within the sealing frame 201, sealing the front end of the sealing frame 201, and thus protecting the first and second gears.

[0035] It should be noted that the foot-operated thresher 100, sealing frame 201, spring 208, elastic plate 203, and nylon rope 210 mentioned above are all components with relatively mature existing technology. Specific models can be selected according to actual needs, and will not be elaborated here.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
