[0055] To enable those skilled in the art to better understand the technical solutions of the present invention, the following will further introduce the present invention in detail in conjunction with the accompanying drawings.

[0056] See Figures 1 to 4 as shown;

[0057] This embodiment discloses a chestnut oil-tea shelling machine, which includes:

[0058] frame 1;

[0059] A drive assembly integrated into the frame 1; and

[0060] A roller pricking mechanism 4 is installed at the power output end of the driving assembly, and the roller pricking mechanism 4 has two sets of pricking rollers 404, and the space between the two sets of pricking rollers 404 is a shell separation space;

[0061] A feed guide plate 3 is provided on the frame 1, and one end of the feed guide plate 3 is a feed section 301, and the other end of the feed guide plate 3 extends into the shell separation space to form a pressure guide section 302;

[0062] The pressure guiding section 302 adjusts the distance from the two groups of licker-in rollers 404 through the pressure guiding rod structure on the side, thereby adjusting the size of the shell separation space at the corresponding position to adapt to the size of fruits of different sizes.

[0063] Specifically, the present embodiment discloses a shelling machine suitable for shelling chestnuts and tea-oil fruits, the main body of which is a frame 1, and a driving assembly is installed above the frame 1 to drive the roller pricking mechanism 4 below to move, and the roller pricking mechanism 4 of the present embodiment has two groups of pricking rollers 404, and the two groups of pricking rollers 404 rotate in opposite directions, and specifically rotate inward, so that the fruit shells can be pierced by the roller prickings 405 of the pricking rollers 404, and in order to adapt to the removal of fruit shells of different sizes, the present embodiment is designed with a feed guide plate 3, and the front half of the feed guide plate 3 is the feed section 301, which is mainly used to guide the fruit into the roller pricking mechanism 4 through its inclined surface, and the rear half of the feed guide plate 3 extends between the two groups of pricking rollers 404, and the size of the fruit shell separation space is adjusted by adjusting the distance with the two groups of pricking rollers 404, so that it can adapt to the removal of fruit shells of different sizes. The shelling machine of this embodiment adopts the roller thorn 405 of the roller thorn mechanism 4 to crush the fruit shell, which can reduce the seed breakage rate of the green shell of the oil-tea fruit and facilitate the roller thorn 405 to pierce the chestnut thorn mass, thereby meeting the shelling requirements of the oil-tea fruit and the chestnut.

[0064] Preferably, the rack 1 of this embodiment is a steel frame structure;

[0065] The driving assembly of this embodiment includes a driving motor 201 provided with a top crossbeam of the frame 1; a reducer 202 drivingly connected to the output end of the driving motor 201; and a roller 204 drivingly connected to the output end of the reducer 202;

[0066] The roller piercing mechanism 4 is connected to the roller shaft 204 so as to be driven to rotate by the driving motor 201 .

[0067] Among them, since the device of the present application needs to synchronously drive two sets of spiked rollers 404 to rotate, therefore, the speed reducer 202 of this embodiment adopts a double-output-shaft speed reducer of the YZSY model series; when selecting the double-output-shaft speed reducer, the power requirements for the shelling operation should be considered, and according to the rotation direction requirements of the two sets of spiked rollers 404, the double-output shaft is used to drive the roller shafts 204 to rotate synchronously, so as to synchronously drive the two sets of spiked rollers 404 to rotate.

[0068] Specifically, each output shaft of the speed reducer 202 of this embodiment drives a set of spiked rollers 404 to rotate, and the two output shafts rotate in opposite directions to drive the two sets of spiked rollers 404 to rotate towards the inner side of the spiked roller group.

[0069] In addition, as an extended implementation method, this embodiment can select a double-output-shaft speed reducer as the transmission mechanism, or drive the two roller shafts 204 to rotate through necessary gear components. The structure for synchronously driving the two roller shafts 204 is common in the prior art, so it will not be elaborated here.

[0070] Preferably, one end of the feeding section 301 of the feeding guide plate 3 of this embodiment extends to the outside of the frame 1, and the feeding section 301 extends obliquely from one end outside the frame 1 to one end of the pressure guiding section 302;

[0071] The pressure guiding section 302 extends obliquely from the end connected to the feeding section 301 to the lower end of the pressure guiding section 302;

[0072] The inclination gradient of the pressure guiding section 302 is greater than that of the feeding section 301.

[0073] First of all, according to the function of the feeding guide plate 3, it is divided into two parts: the feeding section 301 in the first half and the pressure guiding section 302 in the second half; and the feeding section 301 extends to the outside of the frame 1 to divert the fruits to the fruit shell separation space. Therefore, it is arranged as a diversion plate with a smaller gradient; while the pressure guiding section 302 is the part that cooperates with the two sets of spiked rollers 404. Its main purpose is to ensure that the space between the pressure guiding section 302 and the spiked rollers 404 meets the separation requirements for fruit shells of corresponding sizes by adjusting the distance from the two sets of spiked rollers 404, and use the roller spikes 405 to pierce the fruit shells and then separate the fruits and the outer shells.

[0074] Preferably, the pressure guiding rod structure of this embodiment is integrated into the integrated frame inside the frame 1, and two sets of pressure guiding rod structures are distributed along the vertical direction in the integrated frame;

[0075] The two sets of pressure guiding rod structures are divided into the first pressure guiding rod structure 41 located above and the second pressure guiding rod structure 42 located below;

[0076] The first pressure guiding rod structure 41 abuts against the corresponding position of the pressure guiding section 302 and forms a large fruit shelling space 11 with the two sets of spiked rollers 404;

[0077] The corresponding position of the second pressure guide rod structure 42 abuts against the pressure guiding section 302, and a shelling space 12 for small fruits is formed between the two sets of threshing cylinders 404.

[0078] Among them, the pressure guide rod structure of this embodiment includes:

[0079] A pressure guide rod; and

[0080] A pressure spring 403 sleeved on the pressure guide rod;

[0081] The front end of the pressure guide rod is configured as an abutting end 402 for abutting against the pressure guiding section 302. The rear end of the pressure guide rod is a guide rod 401 connected to the abutting end 402. The cross-sectional dimension of the abutting end 402 is larger than that of the guide rod 401;

[0082] The pressure spring 403 is sleeved on the guide rod 401. One end of the pressure spring 403 abuts against the end of the abutting end 402, and the other end of the pressure spring 403 abuts against the integrated frame. The pressure spring 403 is in a compressed state.

[0083] This embodiment further defines the specific structure and working principle of the pressure guide rod structure. First, according to the setting position requirements of the large fruit station and the small fruit station, this embodiment adjusts the corresponding position of the pressure guiding section 302 through the pressure guide rod structure. Specifically, the abutting end 402 at the front end of the guide rod 401 presses the pressure guiding section 302 tightly. Then, the guide rod 401 passes through the integrated frame, and the pressure spring 403 that is always in a compressed state is installed at a specified position. The position of the guide rod 401 and the abutting end 402 is maintained through the pressure spring 403, so that a reaction force can be provided during shelling to make the fruit close to the roller thorns 405, and there is a certain spring-back effect to avoid jamming when the roller thorns 405 rotate.

[0084] Since the lower end of the pressure guiding section 302 of this embodiment is the discharge port, in order to prevent the discharge port from being blocked by impurities such as fruit shells due to accumulation, an anti-blocking pull rod 6 is provided on the integrated frame of this embodiment;

[0085] The front end of the anti-blocking pull rod 6 is connected to the position of the pressure guiding section 302 close to its lower end. The other end of the anti-blocking pull rod 6 passes through the integrated frame and extends to the outside of the machine frame 1. The end of the anti-blocking pull rod 6 extending to the outside of the machine frame 1 is configured as a pulling end. The anti-blocking pull rod 6 can pull the pressure guiding section 302 to bend outward to increase the size of the internal space.

[0086] Preferably, a housing is provided outside the roller thorn mechanism 4 of this embodiment. The housing is configured as a rectangular shell with an open structure on the side facing the pressure guiding section 302;

[0087] Both the upper end and the lower end of the housing are of open structure;

[0088] A material trough 5 is placed at the bottom of the machine frame 1, and all the separated fruit shells fall into the material trough 5.

[0089] The huller in this embodiment is mainly used for hulling chestnuts and oil-tea fruits, so it can be divided into the following two parameter requirements:

[0090] When processing chestnuts with this huller, the height of the roller thorns 405 of the threshing roller 404 is less than twice the thickness of the burr chestnut skin, and the distance between adjacent roller thorns 405 is less than 50 mm;

[0091] When processing oil-tea fruits with this huller, the height of the roller thorns 405 of the threshing roller 404 is less than three times the thickness of the oil-tea fruit skin, and the distance between adjacent roller thorns 405 is less than 15 mm.

[0092] In order to improve the applicable range of the huller in this embodiment, one end of the guide rod 401 far from the abutting end 402 is threadedly connected to the integrated frame;

[0093] The guide rod 401 adjusts the distance between its front end and the pressure guiding section 302 and the two threshing rollers 404 through the threaded connection with the integrated frame.

[0094] In the above technical solution, a chestnut and oil-tea huller provided by the present invention has the following beneficial effects:

[0095] The huller of the present invention drives the two threshing rollers 404 to rotate synchronously by using the driving component, controls the rotation directions of the two threshing rollers 404 and adjusts the distance between the pressure guiding section 302 and the corresponding threshing roller 404 by using the pressure guide rod structure, so that a space for processing fruit shells of corresponding sizes can be formed between the pressure guiding section 302 and the corresponding threshing roller 404. And through the adjustment of the upper and lower two pressure guide rod structures, the position of the pressure guiding section 302 can be controlled so as to adapt to the hulling requirements of large fruits and small fruits. The device uses the threshing roller 404 to replace the existing hulling structure, which can reduce the seed-breaking rate of the green shells of oil-tea fruits and can directly penetrate into the outer shell of the thorn mass to achieve the purpose of crushing the thorn mass.

[0096] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways.
