Description

Technical Field

[0001] This utility model relates to the field of peanut production equipment technology, and in particular to a novel roller screen for a mobile peanut destoner. Background Technology

[0002] Currently, peanut shelling machines require destone removal before shelling. Peanut destone machines are used to remove gravel and debris mixed in with peanuts after harvesting by peanut picking machines. For example, Chinese Patent 2023230675212 discloses a mobile peanut destone machine, which includes: a soil filter screen located below the collection hopper, a conveyor belt connected to the outlet of the soil filter screen for conveying the destone-removed peanuts to the gravity separator, and an elevator connected to the outlet of the gravity separator for conveying the destone-removed peanuts to the peanut shelling machine. By installing a soil filter screen between the gravity separator and the collection hopper, the soil can be discharged in advance, which improves the efficiency of the gravity separator and ensures more thorough screening. However, since the filter screen uses a traditional plate screen, its screening efficiency is low. To improve efficiency, the only way is to increase the running speed of the conveyor belt and the plate screen. However, increasing the running speed will reduce the cleanliness of the plate screen, thereby increasing the burden on the subsequent gravity separation device. In addition, since the whole machine is a self-propelled vehicle, its size cannot be too large, which means that the plate screen cannot be enlarged to improve screening efficiency. Utility Model Content

[0003] In view of the above problems, the purpose of this utility model is to provide a new type of roller screen for a peanut mobile destoner, which replaces the plate screen by adding a roller screen and solves the problem of insufficient space by using a disc rotating elevator.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A novel rotary screen for a mobile peanut destoner includes: a peanut destoner, improved by installing a rotary screen inside the peanut destoner for initial screening, impurity removal, and soil filtering of peanuts. The inlet end of the rotary screen receives peanuts to be impurized, and the outlet end of the rotary screen is connected to a rotary disc conveyor. The rotary screen includes a circular roller, filter holes formed on the circular roller, and a roller drive mechanism for driving the circular roller to rotate. The rotary disc conveyor includes: a conveying disc frame, a conveying disc rotatably connected to the conveying disc frame, and a mechanism for driving the conveying disc to rotate on the conveying disc frame. The rotating conveyor drive mechanism has a circular conveying cavity on the conveying disc. The cross-section of the circular conveying cavity is U-shaped with the outer ring side sealed and the inner ring side open. Multiple radial scrapers for lifting materials are arranged at intervals inside the circular conveying cavity. The inner ring opening at the lowest position of the circular conveying cavity is connected to the discharge port of the roller screen, and the inner ring opening at the highest position of the circular conveying cavity is connected to the inlet of the gravity separator. The conveying disc rotates on the conveying disc frame and conveys the peanuts at the lower position in the circular conveying cavity to the higher position before being discharged.

[0006] As a preferred embodiment of this utility model, the feeding tray frame is equipped with a receiving plate that partially blocks the inner ring opening of the annular feeding cavity. The upper edge of the receiving plate is connected to the top material drop point, and the lower edge of the receiving plate is connected to the bottom material drop point, or the lower edge of the receiving plate is connected to the vicinity of the inner ring opening in the middle of the annular feeding cavity.

[0007] As a preferred embodiment of this utility model, when the feeding disc on the feeding disc frame rotates counterclockwise, the receiving plate blocks the inner ring opening position between the three o'clock and twelve o'clock positions of the annular feeding cavity; or when the feeding disc on the feeding disc frame rotates clockwise, the receiving plate blocks the inner ring opening position between the nine o'clock and twelve o'clock positions of the annular feeding cavity.

[0008] As a preferred embodiment of this utility model, the receiving plate is a crescent-shaped baffle, and the bottom of the crescent-shaped receiving plate is fixed to the conveyor tray frame by a spring.

[0009] As a preferred embodiment of this utility model, the roller screen is rotatably connected to the frame below the first conveyor belt, the upper oblique inlet of the roller screen is connected to the outlet of the hopper through the first conveyor belt, and the lower oblique outlet of the roller screen is connected to the inner ring opening of the annular conveying chamber at its lowest position.

[0010] As a preferred embodiment of this invention, a cleaning conveyor belt is provided below the roller screen, which is used to receive the impurities separated by the roller screen.

[0011] As a preferred embodiment of this utility model, the conveyor drive mechanism includes: a drive motor, a pulley, a belt, and a transmission roller. The transmission roller is rotatably connected to the support frame via a rotating shaft seat. The transmission roller is fixedly connected to the pulley. The pulley is connected to the drive shaft of the drive motor via a belt. The drive motor drives the transmission roller to rotate via the belt. The transmission roller drives the material conveyor disc to rotate.

[0012] As a preferred embodiment of this utility model, the roller drive mechanism includes: a rotating shaft mounted on both sides of the circular roller, a drive gear mounted on the rotating shaft, a motor, and a chain connecting the drive gear and the output end of the motor. The circular roller is rotatably connected to the frame of the peanut destoner via the rotating shafts on both sides. The motor drives the drive gear via the chain, and the drive gear drives the circular roller to rotate via the rotating shaft.

[0013] The advantages and positive effects of this utility model are:

[0014] 1. This utility model solves the problems of traditional plate screens, such as easy clogging, small screening area, high failure rate, and damage to the entire machine due to front-to-back vibration, by replacing the plate screen with a roller screen. The roller screen can improve the soil screening efficiency, thereby improving the initial selection efficiency. In addition, since the roller screen occupies a lot of space, traditional conveyor belts cannot be used. This application not only improves the transfer efficiency of peanuts by using a disc rotary conveyor, but also solves the problem of insufficient space.

[0015] 2. The rotary disc conveyor of this utility model adopts a circular roller conveying method. The radial scraper in the circular conveying chamber carries the material for lifting. Since the conveying disc of the rotary disc conveyor rotates at low speed, some material will fall off during the process of the circular conveying chamber lifting the material to the top high position. Therefore, a half-moon receiving plate is added to block the position where the material is prone to falling. Attached Figure Description

[0021] In the following description, numerous specific details are set forth for illustrative purposes and to provide a thorough understanding of one or more embodiments. However, it will be apparent that these embodiments may also be implemented without these specific details. In other instances, well-known structures and devices are shown in block diagram form for ease of description of one or more embodiments.

[0022] See Figure 1-4 This embodiment provides a novel rotary screen for a mobile peanut destoner, comprising: a mobile destoner, which includes: a hopper 1 for receiving peanuts, a first conveyor belt 2 located below the hopper 1, a rotary screen 3 located below the first conveyor belt 2, and a conveying device 5 connected to the outlet of the rotary screen 3 for conveying the de-soiled peanuts to the inlet of a gravity separator 4. The rotary screen 3 includes a circular roller, filter holes formed on the circular roller, and a roller drive mechanism for driving the circular roller to rotate. The gravity separator 4 is used to separate peanuts, soil, debris, and peanut vine residue by gravity. The hopper 1, gravity separator 4, and rotary screen 3 are all mounted on a support frame 6, which is mounted on a bottom frame 7. The conveying device 5 is a rotary disc conveyor, which includes: a conveying disc frame 501, and a conveyor belt rotatably connected to the conveying disc frame 501. The material tray 502 and the conveyor drive mechanism that drives the material tray 502 to rotate on the material tray frame 501 are provided. The material tray 502 is provided with an annular material conveying cavity 503. The cross-section of the annular material conveying cavity 503 is U-shaped with the outer ring side closed and the inner ring side open. Multiple radial scrapers 504 for lifting materials are arranged at intervals inside the annular material conveying cavity 503. The inner ring opening of the annular material conveying cavity 503 at the lowest position A is connected to the discharge port of the roller screen 3. The inner ring opening of the annular material conveying cavity 503 at the highest position B is connected to the inlet of the gravity separator 4 through the second conveyor belt 9. The second conveyor belt 9 is used to transport the peanuts output by the disc rotary conveyor to the inlet of the gravity separator 4. The input end of the second conveyor belt 9 is located below the inner ring opening at the highest position B of the annular material conveying cavity 503. The output end of the second conveyor belt 9 is connected to the inlet of the gravity separator 4.

[0023] Furthermore, in this embodiment, the upper end flange of the receiving plate 8 is fixedly connected to the second conveyor belt 9, and the lower end flange of the receiving plate 8 is fixedly connected to the conveyor tray frame 501 by a set of springs and is located near the inner ring opening in the middle of the annular conveying cavity 503. The lowest position of the annular conveying cavity 503 is at the six o'clock position, the highest position of the annular conveying cavity 503 is at the twelve o'clock position, and the middle position of the annular conveying cavity 503 is at the nine o'clock and three o'clock positions. When the conveyor tray 502 on the conveyor tray frame 501 rotates counterclockwise, the receiving plate 8 blocks the inner ring opening position between three o'clock and twelve o'clock in the annular conveying cavity 503; or when the conveyor tray 502 on the conveyor tray frame 501 rotates clockwise, the receiving plate 8 blocks the inner ring opening position between nine o'clock and twelve o'clock in the annular conveying cavity 503. The receiving plate 8 is a crescent-shaped baffle, and the bottom of the crescent-shaped receiving plate 8 is fixed to the conveyor tray frame 501 by a spring.

[0024] Furthermore, in this embodiment, the hopper 1 is located at the top front end of the support frame 6, the roller screen 3 is located directly below the hopper 1, the first conveyor belt 2 is installed between the hopper 1 and the roller screen 3, the cleaning conveyor belt 10 is installed below the roller screen 3, the specific gravity separation device 4 is located at the top rear end of the support frame 6, and the disc rotary conveyor 503 is located in the middle of the support frame 6 and between the roller screen 3 and the specific gravity separation device 4.

[0025] Furthermore, the conveyor drive mechanism in this embodiment includes: a drive motor 11, a pulley 12, a belt 13, and a transmission roller 14. The transmission roller 14 is rotatably connected to the support frame 6 via a rotating shaft seat. The transmission roller 14 is fixedly connected to the pulley 12. The pulley 12 is connected to the drive shaft of the drive motor 11 via the belt 13. The drive motor 11 drives the transmission roller 14 to rotate via the belt 13. The transmission roller is made of rubber roller, and the surface of the rubber roller rubs against the outer circumference of the conveyor disc 502, thereby driving the conveyor disc to rotate. Alternatively, the drive mechanism in this embodiment can also use a worm gear, gear teeth, direct motor drive, or other methods to achieve the rotation of the conveyor disc 502.

[0026] Furthermore, the roller drive mechanism in this embodiment includes: a rotating shaft mounted on both sides of the circular roller, a drive gear mounted on the rotating shaft, a motor, and a chain connecting the drive gear and the output end of the motor. The circular roller is rotatably connected to the frame of the peanut destoner via the rotating shafts on both sides. The motor drives the drive gear via the chain, and the drive gear drives the circular roller to rotate via the rotating shaft.

[0027] Working principle: By using a roller screen 3 with higher screening efficiency to replace the traditional plate screen, the screening efficiency of the initial selection is improved. Since the roller screen 3 occupies a large space, the traditional conveyor belt used for lifting cannot be used. This application uses a disc conveyor mechanism to complete the lifting of materials in a smaller space. In addition, since the disc conveyor mechanism uses a low-speed rotation mode, some materials will fall off during the process of lifting the materials to the top high position in the annular conveying chamber 503. Therefore, by adding a half-moon receiving plate to block the position where the materials are prone to falling, it can be ensured that all materials can be lifted and conveyed.

[0028] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
