Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a rice threshing device which is easy to clean. Background Art

[0002] Thresher is a mechanical device used to separate grains from rice ears. Its working principle is to separate the grains from the straw in the rice ears by mechanical force. Traditional thresher plays an important role in agricultural production, but with the development of technology, the existing thresher still has some defects.

[0003] In the southern mountainous areas after the Cold Dew, the traditional thresher is used because of the heavy dew and wet straw. In this case, the adhesion between the straw and the grain increases, making the threshing process more difficult and frequently clogging. The clogging not only affects the work efficiency, but also increases the difficulty of cleaning. Especially in a humid environment, the straw is more likely to be entangled inside the machine, causing more serious clogging. When a clogging occurs, the operator needs to spend a lot of time and energy to disassemble and clean it, which not only affects the production efficiency, but also increases the labor intensity. Traditional threshers also have shortcomings in cleaning residual rice seeds, which can easily lead to grain losses and affect economic benefits. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a rice threshing device that is easy to clean, which solves the problems that the prior thresher is prone to clogging and the residual rice seeds cannot be cleaned up sufficiently.

[0005] In order to achieve the above-mentioned invention object, the technical solution adopted by the present invention is: a rice threshing device that is easy to clean, comprising a frame, a threshing bin arranged on the frame, and a storage box arranged under the threshing bin;

[0006] The threshing bin comprises a box body, on which a machine chamber cover is movably arranged, a feeding port is arranged on the front wall of the box body, and a waste outlet is arranged on the rear wall of the box body; a screen is arranged at the bottom of the box body; a drum is movably arranged inside the box body, and a rotating wheel connected to the drum is arranged outside the box body; a gasoline rotating device is arranged on the side of the box body, and the gasoline rotating device is connected to the rotating wheel.

[0007] The beneficial effects of the present invention are as follows: the threshing device has advantages in terms of easy cleaning, improved work efficiency and reduced maintenance costs, wherein the threshing bin box allows the entire threshing process to be carried out in a relatively closed environment, reducing the spillage and waste of grains. The movable setting of the bin cover provides a convenient opening and closing function, allowing the operator to quickly access the interior for necessary cleaning and maintenance.

[0008] The feed port is located on the front wall of the box, which helps to evenly introduce the rice into the threshing chamber. The rice is effectively threshed by the rotary motion of the drum, which separates the straw from the grain through friction and mechanical impact. A screen is set at the bottom of the box, which can effectively filter out the threshed grains while allowing the incompletely threshed rice to remain in the drum for further processing.

[0009] The application of the gasoline trolley provides a strong and stable power source, and also makes the device extremely flexible in field operations without electricity supply. The connection method between the rotating wheel and the drum ensures efficient power transmission and minimizes energy loss.

[0010] The waste outlet is located on the rear wall, so that impurities generated during the threshing process can be discharged smoothly from the box, reducing the risk of internal blockage, which not only optimizes the threshing efficiency, but also greatly facilitates subsequent cleaning work. Through reasonable arrangement, operators can quickly remove accumulated waste, thereby minimizing the cleaning time of the device and ensuring that it can continue to work efficiently during the busy harvesting season.

[0011] The storage box is set under the threshing bin, and all the grains separated by the screen directly enter the storage box, making the collection process simple and quick, reducing the secondary handling of grains, reducing labor intensity, and also reducing the loss and contamination risk of grains.

[0012] Furthermore, in the above-mentioned rice threshing device which is easy to clean, the drum includes a rotating shaft connected to the rotating wheel, both ends of the rotating shaft are arranged on the box body, at least two round covers are arranged on the rotating shaft, at least two connecting rods are arranged through the round covers, and a plurality of convex teeth are arranged on the connecting rods.

[0013] The beneficial effect of adopting the above further solution is that by arranging a plurality of connecting rods on the round cover and installing convex teeth on the connecting rods, the contact area and frequency with the rice ears can be increased. The convex teeth effectively grab and separate the rice grains during the rotation process, thereby improving the threshing efficiency.

[0014] Furthermore, the easy-to-clean rice threshing device has a cabin cover provided with a guide rail.

[0015] The beneficial effect of adopting the above further solution is that the waste is sent to the waste outlet along the guide rail on the cabin cover and flies out along the inertia.

[0016] Furthermore, in the above-mentioned rice threshing device which is easy to clean, through holes are symmetrically arranged on the top of the side wall of the storage box.

[0017] The beneficial effect of adopting the above further solution is that the through hole allows the user to lift the storage box by hand, or to pass the support rod through the through hole to lift the storage box away.

[0018] Furthermore, in the above-mentioned rice threshing device which is easy to clean, a wooden slide plate is arranged at the bottom of the frame.

[0019] The beneficial effects of adopting the above further scheme are: the wooden slide plate is arranged at the bottom of the frame to improve the mobility of the equipment, and the natural elasticity of the wood can play a role in buffering and shock absorption, which helps to protect the mechanical structure inside the device during movement.

[0020] Furthermore, in the above-mentioned rice threshing device which is easy to clean, the front wall of the box body is provided with an iron buckle for fastening with the cabin cover.

[0021] The beneficial effect of adopting the above further solution is that the iron buckle can improve the sealing between the box body and the cabin cover, preventing the debris generated during the threshing process from leaking out.

[0022] Furthermore, the above-mentioned rice threshing device which is easy to clean is provided with a support frame for placing the gasoline rotating device on the frame body.

[0023] The beneficial effect of adopting the above further solution is that the support frame provides a stable platform for the gasoline rotating device, preventing the device from being displaced due to vibration or movement during operation.

[0024] Furthermore, in the above-mentioned easy-to-clean rice threshing device, the gasoline rotating device is connected to the rotating wheel through a belt.

[0025] The beneficial effect of adopting the above further solution is that the belt can effectively transmit the power of the gasoline rotating device to the rotating wheel. Compared with the gear transmission, the belt transmission system has a simpler structure, fewer parts, and relatively fewer failure points. The belt transmission has a certain elasticity and can absorb and alleviate the vibration and impact from the gasoline engine.

[0026] The beneficial effects of the present invention are as follows: in conventional threshing equipment, clogging problems often lead to reduced production efficiency and even require shutdown for maintenance. The device ensures smooth flow of rice through the feed port on the front wall and the waste outlet on the rear wall. The screen at the bottom not only effectively separates rice from impurities, but also prevents the accumulation of larger particles or debris, thereby reducing the probability of clogging.

[0027] When faced with unavoidable blockages, the device is particularly convenient to disassemble and clean. The cover and the box body are fastened with iron buckles, allowing users to easily open the machine compartment and quickly remove the blockage. Without affecting the stability of the overall structure, the internal parts of the equipment can be quickly disassembled and installed, shortening the maintenance time.

[0028] When processing a small number of trial hybrid rice seeds, the threshing device can quickly remove the remaining seeds in the machine compartment after each threshing through a quick cleaning mechanism, ensuring that the next variety will not be contaminated during threshing, and also improving the purity and quality of each variety of seeds.

[0029] The device is suitable for small-scale, multi-variety experimental planting by scientific research units or breeding institutions. For planting experiments with an area of ​​about 0.02 acres, traditional large-scale machinery often lacks flexibility, and manual operation is not efficient enough. This device provides an ideal solution for small-scale experiments with its compact design and convenient operation. The use of wooden slides not only provides convenience during transportation and positioning, but also reduces vibration to a certain extent, protecting the overall structure of the device.

[0030] In summary, this easy-to-clean rice threshing device solves many problems of traditional equipment in small-scale, multi-variety threshing. It not only improves threshing efficiency and reduces the complexity of manual operation, but also makes an important contribution to ensuring seed purity. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The specific implementation modes of the present invention are described below so that those skilled in the art can understand the present invention. However, it should be clear that the present invention is not limited to the scope of the specific implementation modes. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the attached claims, these changes are obvious, and all inventions and creations utilizing the concept of the present invention are protected.

[0035] In the process of rice planting and harvesting, threshing is an important step. In order to improve the threshing efficiency and ensure the purity of rice seeds, this embodiment provides a rice threshing device that is easy to clean. The device is not only easy to clean, but also can effectively avoid the mixing of varieties, and is particularly suitable for the threshing process of a small number of trial varieties of multiple hybrid rice.

[0036] like Figures 1-2 As shown, the rice threshing device includes a frame 1, a threshing bin 2 arranged on the frame 1, and a storage box 3 arranged under the threshing bin 2; the frame 1 is the supporting structure of the entire device, which is stable and durable. In this embodiment, the frame 1 is welded as a whole with high-strength steel, and has good load-bearing capacity and anti-deformation ability. A wooden slide 18 is provided at the bottom of the frame 1. The surface of the slide is polished and smooth, which reduces the friction with the ground and improves the mobility of the equipment. At the same time, the natural elasticity of the wood can also play a role in buffering and shock absorption, which helps to protect the mechanical structure inside the device during movement.

[0037] The threshing bin 2 mainly includes a box body 4, a bin cover 5, a feed port 6, a waste outlet 7, a screen and a drum 9; the box body 4 is the main part of the threshing bin 2, and in this embodiment, it is made of steel plate, which has sufficient strength and rigidity. The front wall of the box body 4 is provided with a feed port 6, which is convenient for putting rice plants into the threshing bin 2. The rear wall of the box body 4 is provided with a waste outlet 7 for discharging waste (such as leaves, branches and stems) after threshing.

[0038] The machine chamber cover 5 is movably arranged on the box body 4, and is used to close the top of the threshing chamber 2. A guide rail is arranged on the machine chamber cover 5, so that the waste material can slide along the guide rail to the waste material outlet 7. In addition, an iron buckle 19 is also arranged at the front end of the machine chamber cover 5, which is used to buckle with the box body 4 to ensure the stability of the machine chamber cover 5 during the threshing process.

[0039] The screen is arranged at the bottom of the box 4 to separate grains and waste. The aperture of the screen is moderate, which can ensure that grains can pass smoothly and effectively block waste. The material in this embodiment is stainless steel, which has the characteristics of corrosion resistance and wear resistance.

[0040] The drum 9 is a key component in the threshing chamber 2, which is responsible for stirring the rice plants for threshing. The drum 9 includes a rotating shaft 12 and a round cover 13. The two ends of the rotating shaft 12 are arranged on the box body 4, and are driven to rotate by the rotating wheel 10. The round cover 13 is fixedly arranged on the rotating shaft 12, and a plurality of connecting rods 14 are arranged through the round cover 13, and the connecting rods 14 are evenly distributed with convex teeth 15.

[0041] The storage box 3 is arranged below the threshing bin 2 for collecting the threshed grains. The top of the side wall of the storage box 3 is symmetrically provided with through holes 17, which allow the user to lift the storage box 3 by hand, or to pass a support rod through the through hole 17 to lift the storage box 3 away, so as to facilitate the collection and transfer of grains.

[0042] When rice is harvested, rice plants cut into any length are placed into the threshing chamber 2 through the feeding port 6. As the drum 9 rotates, the rice plants are stirred and subjected to collision and friction by the convex teeth 15, thereby achieving threshing. The threshed grains are subjected to gravity and vibration, and fall into the storage box 3 through the screen, while the waste is guided by the guide rail 16 inside the chamber cover 5, sent to the waste outlet 7 and flies out of the chamber.

[0043] After harvesting one variety of rice plants, turn off the gasoline rotating device 11, open the machine cover 5, use a hair dryer to blow away the rice seeds remaining on the inner cylinder and the screen of the machine, and ensure that the inside of the machine is clean. Then fasten the machine cover 5 and continue the harvesting operation of the next variety.

[0044] The rice threshing device not only solves the problem of easy clogging and difficult cleaning of traditional threshing equipment, but also makes significant progress in maintaining the purity of rice seeds. The device is suitable for threshing occasions of multiple hybrid rice trial varieties, especially in small-scale test fields with an area of ​​about 0.02 acres. Due to its high efficiency and convenience, it can quickly switch between different varieties, which provides strong technical support for seed breeding research in seed research institutions and small agricultural experimental units.
