Description

Technical Field

[0001] This utility model relates to the technical field of cashew nut production and processing equipment, specifically a grading and screening machine for cashew nut production and processing. Background Technology

[0002] Against the backdrop of the rapid development of China's food industry, cashews, as a high-quality nut raw material, require particularly important grading and screening during their production and processing. Cashew grading and screening machines are specialized mechanical equipment used for grading and screening cashews during processing. These machines are mainly used to classify cashews, ensuring that cashews of different sizes can be collected separately to meet different processing needs and market requirements.

[0003] Chinese Patent Publication No. (CN213435464U) discloses a grading and screening machine for cashew production and processing, including a grading and screening machine casing, a first-stage cashew screening screen, a second-stage cashew screening screen, a third-stage cashew screening screen, a first-stage cashew discharge hopper, a second-stage cashew discharge hopper, a third-stage cashew discharge hopper, a cleaning plate, quick-release bolts, a drain valve, a guide pipe, a baffle, a handle, a cashew rinsing buffer hopper structure, an adjustable cashew iron impurity adsorption plate structure, and an adjustable movable base frame structure. The first-stage cashew screening screen, the second-stage cashew screening screen, and the third-stage cashew screening screen are screwed together from top to bottom inside the grading and screening machine casing.

[0004] The aforementioned comparative document mainly improves the cleaning efficiency of cashews by setting up components such as connecting pipe heads, cleaning drains, rinsing nozzles, buffer hoppers, drain pipes, and mechanical valves, thereby ensuring the cleanliness of the cashews after washing and providing a good foundation for subsequent grading and cleaning. However, the existing cleaning method has some shortcomings in actual use. Specifically, the cashews are piled up on top of the baffle during the rinsing process, which results in poor rinsing effect on the cashews at the bottom, making it easy for unrinsed residues and dirt to remain. This uneven cleaning effect affects the quality of the washed cashews.

[0005] In view of this, the present invention proposes a grading and screening machine for cashew nut production and processing to solve the above-mentioned technical problems. Utility Model Content

[0006] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for a grading and screening machine for cashew nut production and processing. By incorporating a cleaning component, the cashews are uniformly stirred and cleaned, reducing the possibility of residual residue and dirt, thus ensuring the quality of the cleaned cashews. Simultaneously, a hot air blower is installed at the top of the shell to dry the cashews after cleaning, meeting the needs of subsequent processing. Finally, an auxiliary component, mainly a threaded rod, drives a push plate to operate. The push plate pushes the cleaned cashews from the inner cavity of the water tank into the inner cavity of the shell, effectively preventing cashews from accumulating in the water tank. Furthermore, under the combined action of a spring and a telescopic rod, the push plate automatically adjusts its height according to the inclined surface of the guide plate, ensuring that the bottom end of the push plate always fits against the inclined surface of the guide plate, achieving horizontal pushing. During the movement of the push plate driven by the threaded rod, an intercepting plate also moves synchronously, pushing floating foreign objects on the water surface to one side of the water tank for easy cleaning by the user.

[0007] This utility model provides the following technical solution: a grading and screening machine for cashew production and processing, comprising a shell, a first-stage cashew screening mesh, a second-stage cashew screening mesh, and a cashew discharge hopper;

[0008] A cleaning assembly is fixed to one side of the housing for stirring and cleaning cashews;

[0009] The cleaning assembly includes a water tank, which is fixed to one side of the housing. A first drive motor is fixed to one side of the housing. One end of the output shaft of the first drive motor extends into the inner cavity of the water tank, and multiple stirring blades are fixed on the surface of the output shaft. A discharge trough is provided on the opposite side of the housing and the water tank. A baffle is slidably connected inside the water tank. An electric push rod is fixed to the top of the water tank, and one end of the output rod of the electric push rod is fixedly connected to the top of the baffle.

[0010] A hot air blower is fixed to the top of the inner cavity of the housing;

[0011] The inner cavity of the water tank is rotatably connected to an auxiliary component for pushing the cashew nuts.

[0012] As a preferred embodiment of this utility model, the auxiliary component includes a threaded rod, which is rotatably connected to the inner cavity of the water storage tank. A sliding plate is slidably connected to the surface of the threaded rod, and two connecting columns are fixed to the bottom end of the sliding plate. A telescopic rod is slidably connected to the inner cavity of each of the two connecting columns. A spring is fixed to the opposite surface of the telescopic rod and the connecting column. A push plate is fixed to one end of the telescopic rod, and a second drive motor is fixed to one end of the threaded rod.

[0013] As a preferred embodiment of this utility model, an interceptor plate is fixed to the top of the sliding plate, and a plurality of drainage holes are provided on one side of the interceptor plate.

[0014] As a preferred technical solution of this utility model, a guide plate is fixed at the bottom of the water storage tank cavity below the push plate, and a reserved hole is opened at the top of the guide plate, and a filter plate is fixed in the cavity of the reserved hole.

[0015] As a preferred embodiment of this utility model, a guide groove is provided on the opposite side of the water storage tank, and the surface of the sliding plate is slidably connected to the inner cavity of the guide groove.

[0016] As a preferred embodiment of this utility model, a drain pipe is fixed to both the surface of the shell and the bottom of the water tank, and a valve is provided in the inner cavity of the drain pipe.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This utility model, by setting up a cleaning component, can achieve uniform stirring and cleaning of cashews. Unlike the existing technology where cashews only pile up on top of the baffle for rinsing, the cleaning component of this utility model can ensure that cashews are thoroughly and evenly cleaned during the cleaning process, reducing the problem of residue and dirt remaining on the bottom cashews due to incomplete rinsing. This improved cleaning method effectively ensures the cleanliness of cashews after cleaning and improves the overall quality of cashews.

[0019] 2. This utility model adds a hot air blower to the top of the inner cavity of the shell for drying cashews after washing. This design avoids the problem of cashews becoming moldy or contaminated due to failure to dry them in time after washing, and ensures that the cashews reach the appropriate humidity standard before entering the subsequent processing process.

[0020] 3. By setting up an auxiliary component, the present invention can effectively push the cleaned cashews from the inner cavity of the water tank to the inner cavity of the shell by moving the push plate through the threaded rod, thereby avoiding the accumulation of cashews in the inner cavity of the water tank and reducing the blockage during the cleaning process.

[0021] 4. Under the action of the spring and telescopic rod, the push plate can automatically adjust its height according to the inclined surface of the guide plate, ensuring that the bottom end of the push plate is always in contact with the inclined surface of the guide plate, thus realizing horizontal pushing and making the cashews push more smoothly.

[0022] 5. The threaded rod of this utility model moves the push plate and the interception plate at the same time, pushing the foreign objects floating on the water surface to one side of the water tank, simplifying the cleaning of floating objects, and allowing users to clean up floating objects conveniently and quickly.

A cleaning assembly is fixed to one side of the housing 1 for stirring and cleaning the cashews. The cleaning assembly includes a water tank 2, which is fixed to one side of the housing 1. A first drive motor 201 is fixed to one side of the housing 1. One end of the output shaft of the first drive motor 201 extends into the inner cavity of the water tank 2, and multiple... The mixing blade 202 has a discharge chute 203 on the opposite side of the housing 1 and the water tank 2. A baffle 204 is slidably connected inside the water tank 2. An electric push rod 205 is fixed to the top of the water tank 2. One end of the output rod of the electric push rod 205 is fixedly connected to the top of the baffle 204. A hot air blower 3 is fixed to the top of the inner cavity of the housing 1. An auxiliary component is rotatably connected to the inner cavity of the water tank 2 for pushing cashews. The auxiliary component includes a threaded rod 4, which is rotatably connected to the inner cavity of the water tank 2. The surface of the threaded rod 4... A sliding plate 401 is slidably connected to the sliding plate 401. Two connecting posts 402 are fixed to the bottom end of the sliding plate 401. Telescopic rods 403 are slidably connected to the inner cavities of both connecting posts 402. Springs 404 are fixed to the opposite surfaces of the telescopic rods 403 and connecting posts 402. A push plate 405 is fixed to one end of the telescopic rod 403. A second drive motor 406 is fixed to one end of the threaded rod 4. An intercepting plate 5 is fixed to the top end of the sliding plate 401. Multiple drainage holes 501 are opened on one side of the intercepting plate 5. The push plate 405... A guide plate 6 is fixed at the bottom of the inner cavity of the lower water tank 2. A pre-drilled hole 601 is provided at the top of the guide plate 6. A filter plate 602 is fixed in the inner cavity of the pre-drilled hole 601. A guide groove 7 is provided on the opposite side of the water tank 2. The guide groove 7 is mainly used to guide and limit the sliding plate 401. The surface of the sliding plate 401 is slidably connected to the inner cavity of the guide groove 7. A drain pipe 8 is fixed on the surface of the shell 1 and the bottom of the water tank 2. A valve 801 is provided in the inner cavity of the drain pipe 8.

[0031] In use, first pour a certain amount of tap water into the inner cavity of the water storage tank 2, then pour the cashews into the inner cavity of the water storage tank 2, and then start the first drive motor 201, so that the output shaft of the first drive motor 201 drives the stirring blade 202 to rotate, stirring and cleaning the cashews. After stirring and cleaning is completed, start the second drive motor 406, so that the second drive motor 406 drives the threaded rod 4 to rotate. The rotation of the threaded rod 4 drives the sliding plate 401, and the movement of the sliding plate 401 drives the push plate 405 and the intercepting plate 5 to move, pushing... During its movement, plate 405 pushes the cashews that have sunk to the bottom towards discharge trough 203. Simultaneously, spring 404 extends under the action of the inclined surface of guide plate 6, driving telescopic rod 403 downwards. The downward movement of telescopic rod 403 drives push plate 405 downwards, ensuring that the bottom end of push plate 405 remains in contact with the slope of guide plate 6. Furthermore, during its movement, interceptor plate 5 pushes floating debris on the water surface towards one side of the water tank 2's inner cavity. During this pushing process, tap water is discharged through drain hole 501, preventing damage to the interceptor plate. Plate 5 creates resistance. When the push plate 405 and the interceptor plate 5 move into place, the user can clean up the floating objects. After cleaning, open the valve 801 at the bottom of the water tank 2 to allow the tap water in the inner cavity of the water tank 2 to be discharged through the reserved hole 601 and the drain hole 501. Since the inner cavity of the reserved hole 601 is equipped with a filter plate 602, it can prevent cashews from entering the inner cavity of the drain pipe 8. After the water in the inner cavity of the water tank 2 is drained, start the electric push rod 205, so that the output rod of the electric push rod 205 drives the baffle 204 to move upward, so that... After cleaning, the cashews enter the inner cavity of the shell 1 through the inner cavity of the discharge trough 203, and undergo secondary screening through the first-stage cashew screening screen 101 and the second-stage cashew screening screen 102. During the screening process, the hot air blower 3 can be started to dry the cashews. The screened cashews will be discharged from the inner cavity of the shell 1 through the cashew discharge hopper 103. When tap water accumulates at the bottom of the inner cavity of the shell 1, the valve 801 of the inner cavity of the drain pipe 8 on the surface of the shell 1 can be opened to drain the water from the bottom of the inner cavity of the shell 1.
