Description

Technical Field

[0001] This utility model relates to the field of peanut production equipment technology, and in particular to a novel 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 peanut mobile destoner, which adds a roller screen to replace the plate screen and uses a disc rotating elevator to solve the problem of insufficient space.

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

[0005] A novel mobile peanut destoning machine includes: a hopper for receiving peanut pods, a soil filter screen located below the hopper, and a conveying device connected to the pod outlet for conveying the destoned peanut pods to the inlet of a gravity separator. The gravity separator separates the peanut pods, soil, debris, and peanut vine residue by gravity. The hopper, gravity separator, and soil filter screen are all mounted on a support frame, which is mounted on a bottom frame. An improvement is made where the soil filter screen is a roller screen, and the conveying device is a rotary disc conveyor. The rotary disc conveyor includes: a feeding disc frame and components rotatably connected to the feeding disc frame. The system includes a feeding disc and a drive mechanism that rotates the feeding disc on a feeding disc frame. The feeding disc has an annular feeding cavity with a U-shaped cross-section, the outer ring side being sealed and the inner ring side being open. Multiple radial scrapers for lifting materials are spaced apart inside the annular feeding cavity. The inner ring opening at the lowest position of the annular feeding cavity is connected to the discharge port of the roller screen, and the inner ring opening at the highest position of the annular feeding cavity is connected to the inlet of the gravity separator. The feeding disc rotates on the feeding disc frame and transports the peanuts at the lowest position in the annular feeding cavity to the highest 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. Alternatively, the lower edge of the receiving plate is connected near the inner ring opening in the middle of the annular feeding cavity. The lowest position of the annular feeding cavity is at the six o'clock position, the highest position of the annular feeding cavity is at the twelve o'clock position, and the middle position of the annular feeding cavity is at the nine o'clock and three o'clock positions.

[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, a first conveyor belt is provided between the roller screen and the discharge port of the collecting hopper. The first conveyor belt is used to receive peanuts in the collecting hopper and transport them to the roller screen. The bottom discharge port of the collecting hopper is located above the first conveyor belt. The first conveyor belt transports the peanuts with impurities removed to the inlet of the roller screen. The overall screening speed can be indirectly controlled by controlling the transmission speed of the first conveyor belt.

[0010] 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 output side of 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.

[0011] 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.

[0012] As a preferred embodiment of this utility model, a second conveyor belt is provided between the rotary disc conveyor and the feed inlet of the gravity separator. The second conveyor belt is used to transport the peanuts output by the rotary disc conveyor to the feed inlet of the gravity separator. The input end of the second conveyor belt is located below the inner ring opening at the highest position of the annular feeding chamber, and the output end of the second conveyor belt is connected to the feed inlet of the gravity separator. The upper end flange of the receiving plate is fixedly connected to the second conveyor belt, and the lower end flange of the receiving plate is fixedly connected to the feeding disc frame by a set of springs and is located near the inner ring opening at the middle position of the annular feeding chamber.

[0013] As a preferred embodiment of this utility model, the collecting hopper is located at the top front end of the support frame, the roller screen is located directly below the collecting hopper, a first conveyor belt is installed between the collecting hopper and the roller screen, a cleaning conveyor belt is installed below the roller screen, the gravity separation device is located at the top rear end of the support frame, the disc rotary conveyor is located in the middle of the support frame and between the roller screen and the gravity separation device, and the second conveyor belt is located above the gravity separation device.

[0014] As a preferred embodiment of this utility model, the driving 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 to rotate.

[0015] The advantages and positive effects of this utility model are:

[0016] 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.

[0017] 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.

[0018] 3. This utility model adds a first conveyor belt between the drum screen and the discharge port of the collection hopper. The material in the collection hopper is transported to the drum screen by the first conveyor belt. The presence of the first conveyor belt can adjust the overall screening speed, thereby ensuring the balance between the screening of the drum screen and the screening of the gravity separation device.

[0025] See Figure 1-4 This embodiment provides a novel mobile peanut destoner, comprising: a hopper 1 for receiving peanuts, a first conveyor belt 2 located below the hopper 1, a roller screen 3 located below the first conveyor belt 2, and a conveying device 5 connected to the outlet of the roller screen 3 for conveying the de-soiled peanuts to the inlet of a gravity separator 4. The gravity separator 4 is used to separate peanuts, soil, debris, and peanut vine residue by gravity.

The cross-section of the annular conveying cavity 503 is U-shaped with the outer ring side sealed and the inner ring side open. Multiple radial scrapers 504 for lifting materials are spaced apart inside the annular conveying cavity 503. The inner ring opening of the annular 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 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 conveying cavity 503, and the output end of the second conveyor belt 9 is connected to the inlet of the gravity separator 4.

[0026] 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.

[0027] Furthermore, in this embodiment, a first conveyor belt 2 is provided between the discharge port of the roller screen 3 and the collection hopper 1. The first conveyor belt 2 is used to receive peanuts in the collection hopper 1 and transport them to the roller screen 3. The bottom discharge port of the collection hopper 1 is located above the first conveyor belt 2. The first conveyor belt 2 transports the peanuts with impurities removed to the inlet of the roller screen 3. The overall screening speed can be indirectly controlled by controlling the transmission speed of the first conveyor belt 2. The roller screen 3 is rotatably connected to the frame below the first conveyor belt 2. The upper oblique inlet of the roller screen 3 is connected to the output side of the first conveyor belt 2, and the lower oblique discharge port of the roller screen 3 is connected to the inner ring opening of the annular conveying chamber 503 at its lowest position. A cleaning conveyor belt 10 is provided below the roller screen 3 to receive the impurities screened out by the roller screen 3.

[0028] 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.

[0029] Furthermore, the 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.

[0030] The specific gravity separation device 2 in this embodiment adopts the upper and lower dual-wind specific gravity separation device of a kneading peanut thresher with upper and lower dual-wind specific gravity separation device, which is patented with patent number 2020208621631 and patent name 'A Kneading Peanut Threshing Machine with Upper and Lower Dual-Wind Specific Gravity Separation Device'.

[0031] 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.

[0032] 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.
