Description

Technical Field

[0001] This invention relates to the field of agricultural crop processing technology, and in particular to a chestnut dehulling and packaging system. Background Technology

[0002] Chestnut is a deciduous tree whose fruit is the common chestnut. When the fruit is ripe, it has a cup-shaped shell with sharp thorns on the outside. The thorns vary in length and density. When they are dense, they completely cover the outer wall of the chestnut shell, while when they are sparse, the outer wall is visible.

[0003] After chestnuts ripen, the fruits are harvested, and the outer husk needs to be removed, a process commonly known as husk removal. Current methods typically involve manual husk removal during harvesting, or using a simple machine to scratch the husk and then manually removing it. The removed chestnuts are then packaged as a product. The entire process from harvesting to packaging is relatively fragmented, resulting in a cumbersome and complex procedure; moreover, the husk removal process is quite tedious and inefficient. Summary of the Invention

[0004] The purpose of this invention is to provide a chestnut dehulling and packaging system that integrates dehulling and packaging functions, thereby centralizing the process from harvesting to packaging, improving chestnut processing efficiency, and reducing manual labor intensity.

[0008] The packaging device includes a packaging platform and a weighing device. The packaging platform is used to place the packaging box. The outlet of the discharge component is located directly above the packaging platform. The discharge component conveys fruit particles and causes the fruit particles to fall into the packaging box through its outlet. The weighing device is set on the packaging platform for weighing the packaging box.

[0009] The conveying device is used to transport the packaged box filled with fruit to a designated location;

[0010] The controller is communicatively connected to the weighing device, the conveying device, and the discharge assembly.

[0011] The controller is configured such that: the weighing device acquires the weight information of the packaging box and transmits the weight information to the controller; the controller compares the weight information with a weight threshold; if the weight information is equal to the weight threshold, the controller sends a stop signal to the discharging component and a start signal to the conveying device, so that the conveying device transports the packaging box filled with fruit pieces; if the weight information is greater than or equal to the weight of the packaging box and less than the weight threshold, the controller sends a start signal to the discharging component and a stop signal to the conveying device; if the weight information is less than the weight of the packaging box, the controller sends a stop signal to the discharging component and a stop signal to the conveying device.

[0012] Optionally, the packaging platform is a belt conveyor, which is connected to the conveying device. The controller is further configured to: if the weight information is equal to the weight threshold, the controller sends a start signal to the belt conveyor to transfer the packaged box located on the belt conveyor to the conveying device.

[0013] Optionally, the dehulling assembly includes a housing, a dehulling roller, a first screening screen, and a granule hopper. The housing is provided with a feed inlet, and the outlet of the feeding assembly is connected to the feed inlet. The dehulling roller is disposed inside the housing and can be driven to rotate around its own axis for kneading and dehulling the chestnuts to be dehulled that enter through the feed inlet. The first screening screen is used to screen the chestnut hulls and granules after dehulling, and to collect the granules into the granule hopper. The inlet end of the discharge assembly is connected to the inside of the granule hopper to transport the granules in the granule hopper to the packaging box.

[0014] Optionally, the housing includes an upper housing and a lower housing. The upper housing is a cylindrical shape extending horizontally along its central axis. The dehulling roller is coaxially installed inside the upper housing. The feed inlet is opened in the upper housing. Dehulling heads are arranged in an array on the outer circumferential surface of the dehulling roller. The dehulling heads rotate with the dehulling roller to knead the chestnuts to be dehulled. The upper housing has a discharge port that communicates with the lower housing.

[0015] Optionally, the inner wall of the upper housing is provided with an array of resilient contact protrusions.

[0016] Optionally, the feed inlet and the discharge outlet are staggered along the axial direction of the upper housing; and / or the feed inlet is located at the top of the upper housing, and the discharge outlet is located at the bottom of the upper housing.

[0017] Optionally, the decanting assembly further includes a drive wheel, which is rotatable about its own axis and disposed in the housing. The first end of the first screening mesh is rotatable about the housing and can move horizontally relative to the housing. The second end of the first screening mesh serves as the discharge end and is eccentrically rotated with the drive wheel. The rotation axis of the first end of the first screening mesh is parallel to the rotation axis of the drive wheel. As the drive wheel swings, the second end of the first screening mesh can swing to a position lower than the first end of the first screening mesh. The first end and the second end of the first screening mesh are two opposite ends of the first screening mesh in a horizontal direction.

[0018] Optionally, the dehulling assembly further includes a second screening screen, the mesh size of which is smaller than that of the first screening screen. The second screening screen is disposed below the first screening screen. The first screening screen is used to screen chestnut hulls and allow the fruit grains to fall through the mesh of the first screening screen into the second screening screen. The second screening screen is used to screen fruit grains and allow fine impurities to fall through the mesh of the second screening screen.

[0019] Optionally, the feeding assembly and the discharging assembly are screw conveyors; and / or the feeding assembly and the discharging assembly are located on opposite sides of the decanting device.

[0020] Optionally, the packaging device further includes a labeling machine and a sensor, the labeling machine and the sensor being communicatively connected to the controller, the labeling machine being mounted on the conveying device, and the sensor being mounted on the conveying device; the controller is configured such that: the sensor senses the position of the packaging box on the conveying device and transmits the position information to the controller; if the position of the packaging box is relative to the position of the labeling machine, the controller sends a start signal to the labeling machine so that the labeling machine labels the packaging box.

[0021] In this invention, the system integrates the functions of feeding, dehulling, discharging, and packaging chestnuts, which centralizes the process from harvesting to packaging, thereby improving chestnut processing efficiency and reducing manual labor intensity.

[0022] This invention uses a controller to determine various operating conditions, enabling adaptive control of the stopping and starting of the feeding assembly, discharging assembly, conveying device, and packaging device, thus ensuring the orderly connection of each process.

[0023] In this invention, the gap between the dehulling roller and the inner wall of the upper shell forms a kneading space. When the dehulling head rotates to the bottom of the upper shell, the gap between the dehulling head and the bottom of the inner wall of the upper shell is small, while the gap between the outer wall of the dehulling roller and the bottom of the inner wall of the upper shell is large. When the chestnuts to be dehulled switch positions between these two gaps, a kneading motion is formed, thereby improving the dehulling rate. Attached Figure Description

[0032] The chestnut dehulling and baling system proposed in this invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this invention.

[0033] The chestnut dehulling and baling system includes:

[0034] Decapsulation device 100, conveying device 200, baling device 300, and controller 400;

[0035] Please refer to Figures 1 to 3As shown, the conveying device 200 and the packing device 300 are arranged along the length of the system, and the unpacking device 100 and the packing device 300 are arranged along the width of the system, so that the whole system is L-shaped.

[0036] The dehulling device 100 includes a dehulling component 110, a feeding component 120, and a discharging component 130; the feeding component 120 is used to transport the chestnuts to be dehulled into the dehulling component 110, the dehulling component 110 is used to dehull the chestnuts to be dehulled and separate the dehulled chestnuts from the kernels, and the discharging component 130 is used to transport the kernels.

[0037] Please continue to refer to this. Figures 1 to 3 As shown, the feeding assembly 120 and the discharging assembly 130 are screw conveyors. The screw conveyor includes a conveying pipe and coaxially integrated screw conveying blades within the conveying pipe. The screw conveying blades are driven to rotate by an external motor. In this embodiment, the feeding assembly 120 and the discharging assembly 130 are respectively located on adjacent sides of the decoction device 100. In other alternative embodiments, the feeding assembly 120 and the discharging assembly 130 may be located on opposite sides of the decoction device 100.

[0038] Please continue to refer to this. Figure 1 As shown, the chestnut dehulling and packaging system also includes a fruit hopper 114, a chestnut hull hopper 117, and a feeding hopper 118. The inlet of the feeding assembly 120 is connected to the inner cavity of the feeding hopper 117. The chestnut hull hopper 117 and the feeding hopper 118 are located on opposite sides of the dehulling assembly 110. After dehulling by the dehulling assembly 110, the chestnut hulls fall into the chestnut hull hopper 117 and are collected, while the fruit kernels fall into the fruit hopper 114 and are collected. The inlet of the discharge assembly 130 is connected to the inner cavity of the fruit hopper 114 and is used to transport and collect the fruit kernels in the fruit hopper 114.

[0039] The packaging device 300 includes a packaging platform 310 and a weighing device 320. The packaging platform 310 is used to place the packaging box 500. The outlet of the discharge component 130 is located directly above the packaging platform 310. The discharge component 130 conveys fruit pieces and causes the fruit pieces to fall into the packaging box 500 through its outlet. The weighing device 320 is set on the packaging platform 310 for weighing the packaging box 500.

[0040] In this embodiment, the packaging platform 310 is a belt conveyor, preferably a flat belt conveyor. The belt conveyor is horizontally connected to the conveying device 200, so when the packaging platform 310 is started, it can transfer the packaging box 500 onto the conveying device 200. In other alternative embodiments, a portion of the conveying device 200 can be used as the packaging platform 310; in this case, only the conveying device 200 needs to be started to transport the packaging box 500 without needing to transfer it.

[0041] The weighing device 320 can be an existing device, such as a weighbridge, which is placed between the upper and lower belts of a belt conveyor; or the weighing device 320 can be made by itself, for example, by setting a weighing platform between the two rollers of the belt conveyor, and setting a pressure sensor on the weighing platform to convert pressure into weight information; in this embodiment, the packing box 500 is a cuboid with an opening at the top.

[0042] The conveying device 200 is used to transport the packaged box 500 containing fruit pieces to a designated location. In this embodiment, the conveying device 200 is a roller conveyor, which includes a conveyor frame 210, conveying rollers 220 arranged along the length of the system, and a transmission system for driving the conveying rollers 220 to rotate. The roller conveyor is an existing structure and will not be described in detail here.

[0043] In this embodiment, the packaging device 300 further includes a labeling machine 330 and a sensor 340. The labeling machine 330 can be an inkjet printer, laser marking machine, or a conventional labeling machine, such as the P3400 model specifically designed for cardboard boxes. The appropriate model of the labeling machine 330 can be selected based on actual needs. The labeling machine 330 is mounted on the conveyor frame 210 of the conveying device 200. The sensor 340 is used to sense the position of the packaging box 500 on the conveying device 200. The sensor 340 can be a binocular camera, which identifies the position of the packaging box 500 through image acquisition; or it can be a distance sensor, which detects the distance to the packaging box; or it can be a fiber optic sensor, which includes a transmitter and a receiver positioned opposite each other. When the packaging box is not between the transmitter and receiver, the transmitter sends a signal to the receiver; when the packaging box passes between the transmitter and receiver, the optical path between the transmitter and receiver is blocked, and the receiver loses the signal. In this condition, it is considered that the labeling machine 330 is facing the packaging box. In actual use, the fiber optic sensor can be set on the labeling machine 330. When the optical path of the fiber optic sensor is blocked, it means that the position of the packaging box 500 is opposite to the position of the labeling machine 330.

[0044] In other alternative embodiments, the sensor 340 may also employ other existing technologies, which will not be elaborated here. In other alternative embodiments, the packaging device 300 may also include a tape applicator, a nailing machine, etc., which can be existing packaging equipment selected based on the functional adaptability required in the packaging process, and will not be elaborated here.

[0045] The controller 400 is communicatively connected to the weighing device 320, the conveying device 200, the discharging assembly 130, the sensor 340, and the labeling machine 330.

[0046] The sensor 340 is mounted on the conveyor frame 210 of the conveying device 200, and the sensor 340 transmits the sensed position information to the controller 400.

[0047] The weighing device 320 transmits the detected weight information to the controller 400; the controller 400 analyzes the operating conditions based on the received information and adaptively issues a stop or start signal to control the start or stop of each unit.

[0048] The controller 400 may include a CPU or other general-purpose processor, as well as a display, memory, etc.; the controller may also be a programmable logic device or a software system integrated into a host computer.

[0049] The controller 400 is configured to:

[0050] The weighing device 320 acquires the weight information of the packaging box and transmits the weight information to the controller 400. The controller 400 compares the weight information with a weight threshold. If the weight information is equal to the weight threshold, it means that the weight of the fruit in the packaging box 500 has reached a predetermined value. Then, the controller 400 sends a stop signal to the discharge assembly 130, and the discharge assembly 130 stops conveying fruit into the packaging box 500. At the same time, the controller 400 sends a start signal to the conveying device 200 and the belt conveyor, i.e., the packaging platform 310. The belt conveyor starts to transfer the packaging box 500 located on the belt conveyor to the conveying device 200. Simultaneously, the conveying device 200 starts to transport the packaging box 500 filled with fruit to a designated position.

[0051] If the weight information is greater than or equal to the weight of the packaging box and less than the weight threshold, it means that the fruit pieces in the packaging box have not reached the predetermined weight. Then, the controller 400 sends a start signal to the discharge component 130, and the discharge component 130 conveys the fruit pieces into the packaging box. The controller 400 also sends a stop signal to the conveying device 200 to save energy.

[0052] If the weight information is less than the weight of the packing box itself, it means that there is no packing box on the packing platform. In this case, the controller 400 sends a stop signal to the discharge component 130 and a stop signal to the conveying device 200.

[0053] When the weight information is equal to the weight threshold, and the packaging box is conveyed to the conveying device 200, the sensor 340 senses the position of the packaging box 500 on the conveying device 200 and transmits the position information to the controller 400. If the position of the packaging box 500 is vertically or horizontally opposite to the position of the labeling machine 330, the controller 400 sends a start signal to the labeling machine 330 so that the labeling machine 330 labels the packaging box 500.

[0054] The aforementioned weight threshold can be a set value or a set range, and the weight threshold can be adjusted adaptively based on actual needs.

[0055] In other alternative implementations, the controller 400 can also communicate with other packing devices and detect the position of the packing box via the sensor 340. When the packing box corresponds to the position of other packing devices, the controller 400 controls the other packing devices to start.

[0056] Furthermore, such as Figure 4 and Figure 5 As shown, the dehulling assembly 110 includes a housing 111, a dehulling roller 112, a first screening screen 113, and a fruit hopper 114, wherein the side of the housing 111 is provided with a fruit outlet 1116, and the fruit hopper 114 is externally connected to the fruit outlet 1116.

[0057] The housing 111 is provided with a feed inlet 1111, and the outlet of the feed assembly 120 is connected to the feed inlet 1111. Specifically, the outlet of the feed assembly 120 is located directly above the feed inlet 1111, so that the chestnuts to be shelled fall from the outlet of the feed assembly 120 into the feed inlet 1111.

[0058] Please continue to refer to this. Figures 3 to 5 As shown, the first screening screen 113 is used to screen the chestnut husks and kernels after dehulling, and to collect the kernels into the kernel hopper 114. The inlet end of the discharge component 130 is connected to the inside of the kernel hopper 114 to transport the kernels in the kernel hopper 114 to the packaging box 500.

[0059] The decoupling assembly 110 also includes a drive wheel 115, which is disposed on the housing 111 and can be driven to rotate about its own axis.

[0060] The first end of the first screening screen 113 ( Figure 5 The right end of the first screening screen 113 is rotatably mounted on the housing 111, and this end can move left and right relative to the housing 111 in the horizontal direction. Specifically, the right end of the first screening screen 113 can rotate with the slider, and the slider and the housing 111 slide left and right in the horizontal direction.

[0061] The second end of the first screening screen 113 ( Figure 5 The left end of the first screening screen 113 serves as the discharge end and is eccentrically coupled to the first drive wheel 115. The rotation axis of the first drive wheel 115 is parallel to the rotation axis of the first end of the first screening screen 113. The second end of the first screening screen 113 can swing to a position lower than the first end of the first screening screen 113 as the first drive wheel 115 swings. The first end and the second end of the first screening screen 113 are opposite ends of the first screening screen 113 along a horizontal direction. Please continue to refer to... Figure 5 As shown, when the first drive wheel 115 rotates, the left end of the first screening screen 113 swings up and down and moves back and forth with the first drive wheel 115. At this time, the right end of the first screening screen 113 rotates adaptively and moves left and right in a straight line. The left end of the first screening screen 113 forms a bumpy motion, which is beneficial for screening chestnut husks and fruit granules on the first screening screen 113 and improving screening efficiency. At the same time, when the left end of the first screening screen 113 swings downward and is lower than its right end, the left end of the first screening screen 113 serves as the discharge end, causing the screened chestnut husks to roll from the left end of the first screening screen 113 into the chestnut husk hopper 117.

[0062] If the fruit grains fall below the first screening screen 113, the fruit grain hopper 114 can be set below the first screening screen 113 to receive the fruit grains.

[0063] Please continue to refer to this. Figure 5 As shown, in this embodiment, a secondary screening structure is added. The de-coating assembly 110 also includes a second screening screen 116. The movement structure of the second screening screen 116 is similar to that of the first screening screen 113. The right end of the first screening screen 113 serves as the discharge end, and its left end is eccentrically engaged with the second drive wheel 119. The right end of the first screening screen 113 is engaged with the housing 111 in a vertical swinging or horizontal sliding manner. Both the first drive wheel 115 and the second drive wheel 119 are gears that mesh with each other. In this embodiment, one of the drive wheels is driven to rotate by an external motor.

[0064] The second screening mesh 116 has smaller mesh openings than the first screening mesh 113. The second screening mesh 116 is positioned below the first screening mesh 113. The first screening mesh 113 filters chestnut husks, allowing the fruit grains to fall through its mesh and onto the second screening mesh 116. The second screening mesh 116 filters the fruit grains, allowing small impurities such as chestnut husks to fall through its mesh. When the right end of the second screening mesh 116 swings downwards below its left end, the fruit grains on the second screening mesh 116 roll down through its right end into the fruit grain hopper 114.

[0065] The dehulling roller 112 is disposed within the housing 111. The dehulling roller 112 can be driven to rotate around its own axis to knead and dehull the chestnuts to be dehulled that enter through the feed inlet 1111. One dehulling roller 112 can be provided, and the chestnuts to be dehulled form a kneading motion as they pass through the gap between the dehulling roller 112 and the housing 111; alternatively, multiple dehulling rollers 112 can be provided, and the chestnuts to be dehulled form a kneading motion as they pass through the gap between adjacent dehulling rollers. In this embodiment, the dehulling roller 112 is driven to rotate by an external motor.

[0066] For further details, please refer to... Figures 5 to 7 As shown, the housing 111 includes an upper housing 1112 and a lower housing 1113. The upper housing 1112 is a cylindrical shape extending horizontally along its central axis. The de-coating roller 112 is coaxially mounted inside the upper housing 1112, and the gap between the de-coating roller 112 and the inner wall of the upper housing 1112 forms a kneading space. The feed inlet 1111 is located in the upper housing 1112, and the upper housing 1112 has a discharge outlet 1114 that communicates with the lower housing 1113. The feed inlet 1111 is located at the top of the upper housing 1112, and the discharge outlet 1114 is located at the bottom of the upper housing 1112. Furthermore, the feed inlet 1111 and the discharge outlet 1114 are staggered along the axial direction of the upper shell 1112. Preferably, the feed inlet 1111 and the discharge outlet 1114 are located on opposite sides of the axial direction of the upper shell 1112, so that the chestnuts to be dehulled conveyed into the upper shell 1112 can stay in the upper shell 1112 for a longer time, thereby achieving a higher dehulling rate.

[0067] The outer circumferential surface of the dehulling roller 112 is arrayed with dehulling heads 1121. The dehulling heads 1121 rotate with the dehulling roller 112 to knead the chestnuts to be dehulled. When the dehulling heads 1121 rotate to the bottom of the upper shell 1112, the gap between the dehulling heads 1121 and the bottom of the inner wall of the upper shell 1112 is small, while the gap between the outer circumferential surface of the dehulling roller 112 and the bottom of the inner wall of the upper shell 1112 is large. When the chestnuts to be dehulled switch positions between the two gaps, a kneading motion is formed to improve the dehulling rate.

[0068] Furthermore, the de-drying head 1121 is made of an elastic material, such as rubber or flexible plastic. The de-drying head 1121 is frustoconical, and its smaller diameter end is connected to the outer wall of the de-drying roller 112. The outer wall of the de-drying head 1121 is a tapered slope. When the de-drying head 1121 rotates to the bottom of the upper housing 1112, the gap between the outer wall of the de-drying head 1121 and the bottom of the inner wall of the upper housing 1112 gradually changes, further improving the kneading effect. By setting the taper of the de-drying head 1121 and the radial gap between the larger diameter end of the de-drying head 1121 and the inner wall of the upper housing 1112, the kneading force can be controlled to achieve a better kneading effect.

[0069] The large-diameter end of the dehulling head 1121 has an outwardly convex arc surface. When the dehulling head 1121 rotates to the bottom of the upper shell 1112, the gap between the large-diameter end of the dehulling head 1121 and the bottom of the inner wall of the upper shell 1112 gradually changes, which is used to squeeze and knead the chestnuts to be dehulled located between the large-diameter end of the dehulling head 1121 and the bottom of the inner wall of the upper shell 1112. The outer wall of the dehulling head 1121 is provided with multiple grooves 1122. Preferably, the grooves 1122 are hemispherical grooves, so that during the kneading process, the chestnuts to be dehulled can be partially sunk into the grooves, which gives the dehulling head 1121 an instantaneous gripping ability. This gripping ability helps to position the chestnut hulls located in the grooves. Then, the chestnut hulls in contact with the inner wall of the upper shell 1112 are torn by the kneading force, causing the chestnut hulls located in the grooves to tear from those located on the inner wall of the upper shell 1112, achieving a better dehulling effect.

[0070] Please refer to Figures 6 to 8 As shown, the outer wall of the de-tufting roller 112 has a radially extending rigid connecting rod 1123. The rigid connecting rod 1123 is radially connected to the outer wall of the de-tufting roller 112, and one end of the de-tufting roller 112 is detachably inserted into the rigid connecting rod 1123. The rigid connecting rod 1123 is preferably made of iron, copper, or other metal, where rigidity is contrasted with elasticity. The rigid connecting rod 1123 provides better rigid support for the de-tufting roller 112, while the elastic deformation of the de-tufting roller 112 itself achieves a better kneading effect. Simultaneously, the rigid connecting rod 1123 also facilitates the installation of the de-tufting roller 112.

[0071] Because chestnut husks have many sharp spines, they can easily scratch the husk removal head 1121 during the husk removal process. Therefore, replacing the husk removal head 1121 is a technical issue that must be considered. Please continue to refer to [link / reference needed]. Figure 7As shown, the rigid connecting rod 1123 is a tapered rod whose outer diameter gradually increases radially outward. The small-diameter end of the defrosting head 1121 has a tapered cavity adapted to the rigid connecting rod 1123, and the rigid connecting rod 1123 fits into the tapered cavity. Since the defrosting head 1121 is made of an elastic material, it is pressed onto the rigid connecting rod 1123 by external force, forming a reliable connection between the two. This structure facilitates the replacement of the defrosting head 1121.

[0072] For further details, please refer to... Figure 6 and Figure 7 As shown, the outer wall of the decapitation roller 112 is symmetrically arranged with multiple rows of decapitation heads 1121 along the circumference. Each row has multiple decapitation heads 1121 arranged at equal intervals along the axial direction of the decapitation roller 112, and the decapitation heads 1121 in adjacent rows are staggered along the axial direction of the decapitation roller 112. Therefore, during the rotation of the decapitation roller 112, when each row of decapitation heads 1121 rotates to the bottom of the upper shell 1112, it can knead the empty area of ​​the previous row, which helps to comprehensively improve the decapitation efficiency.

[0073] Please refer to Figures 7 to 8 The inner wall of the upper shell 1112 shown is provided with an array of elastic contact protrusions 1115. The elastic contact protrusions 1115 are made of elastic material, such as rubber or flexible plastic. The elastic contact protrusions 1115 facilitate the retention of the chestnuts to be removed at the bottom of the upper shell 1112 for a longer period of time, and also create a kneading structure between the elastic contact protrusions 1115 and the removal head 1121, thereby improving the kneading effect.

[0074] The elastic protrusion 1115 includes a spherical contact 11151 and an elastic rod 11152. The spherical contact is connected to the inner wall of the upper housing 1112 via the elastic rod. The elastic rod 11152 can be made of rubber. When the elastic protrusion 1115 is compressed, the elastic rod 11152 will bend. When the elastic rod 11152 elastically returns to its original position, it will drive the spherical contact 11151 back to strike the chestnut to be dehulled. This causes the chestnut to change its posture, so that all parts of the chestnut to be dehulled are evenly kneaded, improving the dehulling effect.

[0075] The bottom of the inner wall of the upper shell 1112 is provided with multiple rows of elastic contact protrusions 1115 along the circumferential direction. Specifically, each row of elastic contact protrusions 1115 is located at the lower half of the upper shell 1112, while the inner wall of the upper half of the shell is not provided with elastic contact protrusions 1115. Due to the presence of the elastic contact protrusions 1115, the gap between the inner wall of the lower half of the shell and the uncoating roller 112 is different from the gap between the upper half of the shell and the uncoating roller 112. When the chestnut to be uncoated falls into the upper half of the upper shell 1112 through the feed inlet 13, the gap is relatively large. The compression through the larger gap loosens the chestnut husk, and the chestnut to be uncoated is initially kneaded at this time. Then, the chestnut to be uncoated falls into the upper and lower halves of the upper shell 1112. As the elastic contact protrusions 1115 occupy part of the gap space, the gap becomes smaller, resulting in two-stage kneading of the chestnut to be uncoated.

[0076] Each row is provided with multiple elastic contact protrusions 1115 arranged at equal intervals along the axial direction of the upper housing 1112, and the elastic contact protrusions 1115 in adjacent rows are staggered along the axial direction of the upper housing 1112. This staggered arrangement facilitates contact with the chestnuts to be dehulled at various positions. Moreover, as the dehulling head 1121 rotates with the dehulling roller 112, it forms a kneading effect with the elastic contact protrusions 1115 in each row. Due to the axial staggering of the dehulling heads 1121 and the elastic contact protrusions 1115 in each row, the contact position of the dehulling head 1121 changes during the kneading process, thereby increasing the kneading coverage of the chestnuts to be dehulled and improving the dehulling efficiency and dehulling rate.

[0077] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0078] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
