Abstract
Description
Technical Field
[0001] This utility model relates to the field of wheat threshing technology, and in particular to a portable wheat threshing machine. Background Technology
[0002] A wheat thresher is an agricultural machine used to separate wheat grains from the ears and stalks after wheat harvest. Its core function is to replace the traditional manual threshing method. Through mechanical force, it efficiently and quickly completes the separation of wheat grains from husks and stalks, greatly reducing the labor intensity of farmers, improving the processing efficiency after wheat harvest, and laying the foundation for subsequent wheat grain cleaning, drying, storage, or processing.
[0003] An investigation revealed that a Chinese utility model patent, CN112715170A, discloses an anti-clogging wheat thresher. This invention includes a feeding hopper, a crushing pipe, a vibrating motor, a crushing column, a first stirring paddle, and a second stirring paddle. The crushing pipe is located below the feeding hopper and has a discharge port at its bottom. The inner wall of the crushing pipe is connected to the first and second stirring paddles via a first and second stirring shaft, respectively. The upper and lower ends of the crushing pipe are connected to movable plates via a first and second support rod, respectively. The movable plates are slidably connected to a groove on the inner wall of the machine housing. The second support rod is connected to a vibrating motor embedded in the top of the machine housing via a vibrating rod. The crushing column is connected to a second servo motor via a drive shaft and to a fixed plate via a first damping spring. A brush is fixedly connected to the bottom of the fixed plate. This invention is characterized by its resistance to clogging.
[0004] When users operate the aforementioned patent, they directly feed the wheat straw through a simple inlet, which causes the wheat straw to scatter and accumulate when it enters the threshing area. Some wheat falls outside the equipment before entering the threshing area, resulting in material waste and affecting the quality of the wheat. It is also prone to clogging when filtering impurities, and multiple fasteners need to be disassembled for cleaning or replacement, making the operation cumbersome. The separated wheat grains often contain a lot of wheat husk impurities, resulting in low cleanliness.
[0005] Therefore, a portable wheat thresher is particularly needed. Utility Model Content
[0006] The purpose of this invention is to provide a portable wheat thresher to solve the problems mentioned in the background section.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a portable wheat threshing machine, comprising a machine body, an upper operating base plate fixedly connected to the upper surface of the machine body, casters fixedly connected to the bottom surface of the machine body, and a threshing mechanism installed on the upper surface of the upper operating base plate; The threshing mechanism includes a collecting shell mounted on an upper operating base plate. A material guiding shell is fixedly connected to the upper surface of the upper operating base plate. A fixing block is fixedly connected to one side of the material guiding shell. A motor is fixedly connected to one side of the fixing block. A roller is fixedly sleeved at the top of the output shaft of the motor. A threshing roller is fixedly connected to one side of the roller. A threshing and knocking plate is fixedly connected to one side of the threshing roller. A material guiding plate is fixedly connected to the upper surface of the material guiding shell. An upper docking frame is fixedly connected to the outer ring surface of the material guiding plate. A material discharge processing cross plate is fixedly connected to one side of the material guiding shell.
[0008] Preferably, a pull ring is fixedly connected to one side of the receiving shell, and the pull ring is connected to the machine body through the receiving shell.
[0009] Preferably, the inner surface of the material guide processing shell is provided with an insertion opening, and the size of the insertion opening and the material guide plate are matched.
[0010] Preferably, a filter screen is fixedly engaged on the inner ring surface of the discharge processing plate, and the filter screen is connected to the discharge processing plate and the guide processing shell.
[0011] Preferably, the inner surface of the upper operating base plate is provided with an installation opening, and the installation opening and the retractable shell are structurally compatible.
[0012] Preferably, an extension rod is fixedly connected to the upper surface of the machine body, and the extension rod is symmetrically arranged about the vertical center line of the machine body.
[0013] Preferably, a handle is fixedly connected to one side of the extension rod, and the handle is connected to the machine body through the extension rod.
[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The material processing shell is designed with a guide plate fixed on its upper surface and a connecting frame on the outer ring to form a guide channel. The size of the insertion opening of the guide plate and the inner ring of the material processing shell are matched to ensure that the wheat can enter the threshing area smoothly and accurately, avoiding waste caused by material scattering. The motor output shaft drives the roller and the threshing roller on one side to rotate. The threshing plate on the threshing roller can quickly and evenly beat the wheat to thresh it, effectively separating the wheat grains from the husks and reducing the problem of wheat grain breakage caused by unthreshed or excessive beating. The mixture after threshing enters the discharge processing plate. The filter screen with the inner ring limit clamp can accurately filter impurities such as wheat husks and separate pure wheat grains.
[0015] 2. The universal wheels fixed to the bottom of the machine body facilitate flexible movement of the equipment in fields and sites, making it especially suitable for mobile operations in small-area wheat planting scenarios. The handle provides a comfortable point of force for the operator to push the equipment, and with the flexible steering of the universal wheels, a single person can easily move the equipment. The pull ring fixed on one side of the collection shell allows the operator to quickly pull out the collection shell to clean the collected impurities without disassembling the equipment. The filter screen is connected to the discharge processing plate by a limit snap-fit method, which can be removed for washing or replacement at any time, making maintenance convenient.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0019] Please see Figure 1-5 This utility model provides a technical solution: a portable wheat threshing machine, including a machine body 1, an upper operating base plate 2 fixedly connected to the upper surface of the machine body 1, a universal wheel 4 fixedly connected to the bottom surface of the machine body 1, and a threshing mechanism 3 installed on the upper surface of the upper operating base plate 2. The threshing mechanism 3 includes a collecting shell 301, which is mounted on an upper operating base plate 2. A material guiding shell 304 is fixedly connected to the upper surface of the upper operating base plate 2. A fixing block 305 is fixedly connected to one side of the material guiding shell 304. A motor 306 is fixedly connected to one side of the fixing block 305. A roller 307 is fixedly sleeved at the top of the output shaft of the motor 306. A threshing roller 313 is fixedly connected to one side of the roller 307. A threshing and knocking plate 314 is fixedly connected to one side of the threshing roller 313. A material guiding plate 308 is fixedly connected to the upper surface of the material guiding shell 304. An upper docking frame 309 is fixedly connected to the outer ring surface of the material guiding plate 308. A discharge processing horizontal plate 310 is fixedly connected to one side of the material guiding shell 304.
[0020] Furthermore, a pull ring 302 is fixedly connected to one side of the collection shell 301, and the pull ring 302 is connected to the machine body 1 through the collection shell 301. The pull ring 302 is made of high-strength alloy material and the surface is treated with anti-slip treatment. When the operator cleans the wheat husk impurities collected in the collection shell 301, the collection shell 301 can be easily pulled out from the installation opening 312 through the pull ring 302 without the need for additional tools, thus avoiding direct contact with impurities and preventing contamination.
[0021] Furthermore, the inner surface of the material guide processing shell 304 is provided with an insertion opening 303, and the size of the insertion opening 303 and the material guide plate 308 are matched. The insertion opening 303 is made with a precise dimensional processing technology to form a tight insertion fit with the material guide plate 308, which can ensure that the material guide plate 308 is stable and does not shake after installation, preventing wheat from leaking out of the gaps during the material guiding process, and facilitating the disassembly, maintenance or replacement of the material guide plate 308 in the later stage.
[0022] Furthermore, a filter screen 311 is fixedly attached to the inner ring surface of the discharge processing plate 310, and the filter screen 311 is connected to the discharge processing plate 310 and the guide processing shell 304. The filter screen 311 is made of stainless steel wire and the mesh size is precisely designed to effectively intercept impurities such as wheat husks and wheat stalks.
[0023] Furthermore, the inner surface of the upper operating base plate 2 is provided with an installation opening 312, and the installation opening 312 and the collecting shell 301 are structurally matched. The installation opening 312 and the collecting shell 301 adopt a concave-convex fit structure design to ensure that the collecting shell 301 is seamlessly connected with the upper operating base plate 2 after installation, so as to prevent the broken shells and impurities generated during the threshing process from falling into the equipment or the ground through the gaps, thus reducing the amount of cleaning work.
[0024] Furthermore, an extension rod 315 is fixedly connected to the upper surface of the machine body 1, and the extension rod 315 is symmetrically arranged with the vertical center line of the machine body 1 as the axis of symmetry. The symmetrical extension rod 315 is made of lightweight and high-strength aluminum alloy, which reduces the overall weight of the equipment while ensuring the support strength.
[0025] Furthermore, a handle 316 is fixedly connected to one side of the extension rod 315, and the handle 316 is connected to the machine body 1 through the extension rod 315. The surface of the handle 316 is covered with a soft rubber anti-slip sleeve, and the inside is provided with an ergonomic arc groove. When the operator holds it, the hand fits well, which can effectively distribute hand pressure and avoid hand fatigue caused by pushing the equipment for a long time.
[0026] Working principle: When a user needs to use a portable wheat thresher, the operator holds the handles 316 fixed on the upper surface of the machine body 1 by symmetrically arranged extension rods 315 with both hands. With the help of the casters 4 fixedly connected to the bottom surface of the machine body 1, the equipment is pushed smoothly to the wheat threshing area. The position of the equipment is adjusted according to the site conditions to ensure that the upper operating base plate 2 is in a horizontal state. The equipment is then positioned, and the collection shell 301 is aligned with the installation opening 312 opened on the inner surface of the upper operating base plate 2. Since the installation opening 312 and the collection shell 301 are structurally compatible, the collection shell 301 is directly inserted into the installation opening 312, so that it is firmly installed on the upper operating base plate 2, ready for collecting impurities generated during the threshing process. Check whether the filter screen 311, which is limited and snapped on the inner ring surface of the discharge processing plate 310, is installed in place, and ensure that it is tightly connected to the discharge processing plate 310 and the guide processing shell 304; at the same time, confirm that the guide plate 308 fixed on the upper surface of the guide processing shell 304 matches the size of the insertion opening 303 opened on the inner ring surface of the guide processing shell 304 and is firmly inserted, and that the upper connecting frame 309 on the outer ring surface of the guide plate 308 is not deformed, ensuring that the material guiding channel is smooth. Start the motor 306 fixed on one side of the guide processing shell 304 by the fixing block 305. The roller 307 fixedly sleeved at the top of the output shaft of the motor 306 drives the threshing roller 313 fixed on one side to rotate, and the threshing plate 314 on one side of the threshing roller 313 rotates at high speed accordingly. The wheat straw to be threshed is evenly placed into the guide channel formed by the guide plate 308 and the upper connecting frame 309. Guided by the guide plate 308, the wheat straw enters the guide processing shell 304. Inside the guide processing shell 304, the wheat straw is struck by the high-speed rotating threshing plate 314, achieving the separation of wheat grains from wheat husks and straw. The threshed mixture enters the discharge processing horizontal plate 310 fixed on one side of the guide processing shell 304 and is filtered through the filter screen 311. The wheat grains pass through the filter screen 311 and fall into the preset collection below. The container, wheat husks, and straw are trapped on the filter screen 311. Meanwhile, the fine debris generated during the threshing process falls into the collection shell 301 for collection. After the wheat is threshed, the motor 306 is turned off. By holding the pull ring 302 fixed on one side of the collection shell 301, the collection shell 301 is pulled out from the installation opening 312 to clean the debris collected inside. Then, the filter screen 311 in the discharge processing plate 310 is removed, and the wheat husks and straw trapped on the surface are washed away. After cleaning, all parts are reset to their original positions to complete the entire wheat threshing process.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
