Description

Technical Field

[0001] This utility model relates to the field of rice and wheat threshing machine technology, and in particular to an anti-tangling rice and wheat threshing machine. Background Technology

[0002] A threshing machine is a harvesting machine that separates the grains from the stalks of crops, primarily referring to harvesting machinery for grain crops. Different types of threshing machines exist depending on the type of grain being harvested; for example, equipment used for threshing and separating rice and wheat is called a rice-wheat threshing machine. Most of them adopt a drum structure combined with mechanical force to complete threshing and separation. According to the feeding method, they are divided into two types: full feeding and semi feeding. In the full feeding method, because the stalks are soft and long, some of them are easy to wrap around the outer edge of the drive drum, covering the drum and affecting the drum's rotation efficiency. In some cases, they may even wrap around the drive shaft and cause jamming, affecting normal threshing. In addition, the existing drum and screen plate have a narrow range of impact and threshing, and the separation rate is slow, which cannot meet the high-efficiency threshing operation of crops planted on a large scale, resulting in low overall efficiency. Summary of the Invention

[0003] The purpose of this utility model is to provide an anti-tangling rice and wheat threshing machine that can perform more comprehensive and efficient extrusion and crushing threshing and separation operations on the introduced materials. It has a wider threshing surface, higher crushing efficiency for stalks, and avoids stalks tangling around the drive shaft, thus affecting the normal operation of the machine and improving the overall threshing efficiency.

[0004] To achieve the above objectives, an anti-tangling rice and wheat thresher is provided, comprising: a threshing ring chamber; a screening bin is fixedly connected to the bottom of the threshing ring chamber; a discharge plate is mounted on the lower front side of the screening bin; a base frame is symmetrically fixed to the bottom of the screening bin; a hopper is fixedly connected to the center of the top side of the threshing ring chamber; and a machine sleeve is fixedly connected to the center of the left and right sides of the threshing ring chamber. A first motor and a second motor are respectively fitted and assembled inside the machine sleeve, wherein the first motor is located to the left of the second motor, and the first motor and the second motor are connected... One output end of the threshing ring is fixedly connected to a first drive shaft and a second drive shaft via a coupling. The right end of the first drive shaft extends into the interior of the threshing ring and is fixedly connected to an outer roller. The second drive shaft passes through the outer roller to the left and rotates with it. A ring gasket is engaged and fixed on the outer side of the left end of the second drive shaft. An inner roller is fixedly connected to the left side of the ring gasket. The right side of the inner roller is engaged and rotates with the outer roller. Gaps are reserved between the left and right ends of the outer and inner rollers and the left and right sides of the hopper. Several feeding grooves are arranged in a ring array on the outer sides of both the outer and inner rollers. Several first nail teeth are arranged in a ring array on the outer side of the outer roller, several second nail teeth are arranged in a ring array on the inner side of the outer roller, and several third nail teeth are arranged in a ring array on the outer side of the inner roller. The second and third nail teeth are staggered. By setting up inner and outer double rollers and using an independent drive method for coaxial and counter-rotation, and by opening several feeding grooves in the ring array on the outer sides of the two rollers to guide rice ears and wheat ears into the rollers, the two rollers then form... Several threshing nails are staggered in the interlayer and cover the inner and outer sides of the drum. This allows for a more comprehensive and efficient crushing and threshing process for the introduced material. The threshing surface is wider, and the crushing efficiency of the stalks is higher. The drum is hollow and elongated, which provides a horizontal separation space between the drive shaft and the hopper inlet. This allows the material to enter the drum along the discharge chute, be crushed, and then be screened and discharged from the screening bin. This prevents the stalks from getting tangled in the drive shaft and affecting the normal operation of the machine, thus improving the overall threshing efficiency.

[0005] According to the aforementioned anti-tangling rice and wheat thresher, the top surface of the hopper has an arc-shaped opening design. This reduces the feeding height on both sides and optimizes the feeding angle.

[0006] According to the aforementioned anti-tangling rice and wheat threshing machine, both the first and second drive shafts are rotatably fitted with bushings on their outer sides, and the opposite sides of each bushing are fixedly connected to a motor. This nested protection of the drive shafts prevents stalks from getting caught.

[0007] According to the aforementioned anti-tangling rice and wheat thresher, the screening bin adopts the screening mechanism and blowing design of the 5TG-70 rice and wheat thresher. It utilizes a relatively mature and efficient screening mechanism and blowing impurity removal method currently available on the market.

[0008] According to the aforementioned anti-winding rice and wheat thresher, the right end face of the outer roller is detachable and is tightly fixed to the outer roller body by bolts. This facilitates the detachable nesting combination of the inner and outer rollers, making it easy to replace individual components later.

[0009] According to the aforementioned anti-tangling rice and wheat thresher, the front end of the discharge plate is designed to slope downwards, and baffles are symmetrically fixed on the left and right sides of the top of the discharge plate. This optimizes the discharge path and facilitates rapid collection.

[0010] The above-mentioned solution has the following beneficial effects: In this invention, inner and outer double rollers are set up and driven independently to rotate coaxially in opposite directions. At the same time, several feeding troughs are opened in a ring array on the outer side of the two rollers to help introduce rice ears and wheat ears into the rollers. Then, several threshing nails are arranged alternately in the sandwich formed by the two rollers and are correspondingly filled on the inner and outer sides of the rollers. This allows for a more comprehensive and efficient crushing and threshing separation of the introduced materials. The threshing surface is wider and the crushing efficiency of the stalks is higher. The rollers are hollow and extended, so that the drive shaft and the hopper inlet are separated in the horizontal direction. The incoming materials enter the rollers along the feeding troughs, are crushed inside the rollers, and are then screened and discharged from the screening bin along the feeding troughs. This avoids the stalks from getting tangled in the drive shaft and affecting the normal operation of the machine, thus improving the overall threshing efficiency.

[0011] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
