Description

Technical Field

[0001] The invention relates to the technical field related to walnut shelling, in particular to a walnut shelling and shell-kernel separation integrated machine. Background Art

[0002] The walnut shelling and kernel separation machine is a key piece of equipment in orchard processing. Its development stems from the low efficiency of manual shelling and incomplete kernel-shell separation in traditional walnut processing. With the large-scale development of the walnut planting industry and increasing consumer demand for walnut kernel integrity, this machine integrates shelling, sorting, and separation processes through mechanical automation, significantly improving processing efficiency and product quality while reducing labor costs and breakage rates. It has become a key link in the walnut deep-processing industry and has promoted the intelligent upgrading of the nut processing industry. The walnut shelling and kernel separation machine uses a rotary hammer to crush the incoming walnuts. The crushed shells and kernels are then separated by a fan and roller.

[0003] The existing integrated machine lacks a uniform material distribution device at the feed port, which may lead to uneven material distribution in the conical hammer area and cause local overload. Therefore, a walnut shelling and shell-kernel separation integrated machine with uniform material loading at the feed port is proposed. Summary of the Invention

[0004] The object of the present invention is to provide a walnut shelling and shell-kernel separation integrated machine to solve the problems raised in the above background technology.

[0005] The technical solution adopted in the present invention is:

[0006] The walnut shelling and shell-kernel separation machine includes a box body, a through hole penetrating the box body, a feed box 1 fixed on the top of the box body, and a feed hole opened on the top of the box body. The inner side wall of the feed box 1 is provided with a material guide assembly, and the material guide assembly includes:

[0007] A second shaft is rotatably connected to the inner wall of the first feed box;

[0008] A guide wheel is fixed to the outer wall of the second shaft. When multiple walnuts are introduced onto the guide wheel, the second shaft rotates on the first feed box, and the rotation of the guide wheel intermittently feeds multiple walnuts into the feed hole. A screening assembly is provided on the top of the box, and the screening assembly is used to screen multiple walnuts. The operation of the screening assembly simultaneously drives the second shaft to rotate.

[0009] Optionally, the guide wheel is mainly composed of a plurality of baffles, which are regularly arranged, and an area is formed between every two baffles for limiting the positions of multiple walnuts.

[0010] Optionally, a guide block is symmetrically provided on the inner side wall of the feed box 1, and the outer side wall of the guide wheel is in contact with a side surface of the guide block.

[0011] Optionally, the top surface of the guide block is inclined relative to the horizontal plane.

[0012] Optionally, two guide plates are obliquely provided on the inner side wall of the feed hole.

[0013] Optionally, it is characterized in that the screening component includes:

[0014] Feed box 2 is fixed to the top of the box body and is connected to feed box 1;

[0015] A roller is rotatably connected to the inner side wall of the second feed box, the inner side wall of the roller is fixed with a frame, one side of the frame is fixed with a shaft 1, and the shaft 1 is connected to the shaft 2 through a belt assembly;

[0016] Four guide rollers are provided and fixed on the second feed box to limit the rotation of the drum;

[0017] The motor is fixed on the second feed box, and the output shaft of the motor drives one group of the guide rollers to rotate through a transmission assembly.

[0018] Optionally, a feed box three is fixed on the top of the box body, the feed box three is connected to the feed box two, a hopper is fixed on the top of the feed box three, a discharge port is opened on one side of the feed box two, and a plate is provided on the inner wall of the feed box two.

[0019] Optionally, the belt assembly includes:

[0020] A first synchronous wheel is fixed to one end of the first shaft;

[0021] The second synchronous wheel is fixed to one end of the second shaft, and the second synchronous wheel is connected to the first synchronous wheel through a synchronous belt transmission.

[0022] Optionally, the output end of the motor passes through the transmission assembly and is fixedly connected to shaft body three. A transmission box is fixed on one side of the box body. The output end of the transmission box is fixedly connected to the screen drum, and shaft body three is connected to the transmission box.

[0023] Optionally, the tops of the feed box 2 and the feed box 1 are both open.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] When a large batch of walnuts is introduced into the feed bin, the guide wheels rotate to evenly distribute the walnuts across multiple areas before sequentially feeding them into the feed holes. This precisely controls the feed volume and timing, preventing both clogging of the feed holes and overloading of the crushing hammers. To account for walnut size differences, a pre-screening assembly filters out oversized and undersized walnuts, ensuring uniform walnut size entering the machine and effectively improving the crushing pass rate.

DETAILED DESCRIPTION

[0034] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the products of the present invention are conventionally placed when in use, or are the orientations or positional relationships conventionally understood by those skilled in the art. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0036] In view of the fact that the existing integrated machine feed port lacks a uniform distribution device in the current existing technology, which may lead to uneven material distribution in the conical hammer area and cause local overload, a walnut shelling and shell-kernel separation integrated machine with uniform feeding at the feed port is proposed.

[0037] like Figure 1 and 5 As shown, an embodiment of the present invention provides an integrated machine for walnut shelling and shell-kernel separation, including a box body 100, a through hole 120 passing through the box body 100, a feed box 110 fixed on the top of the box body 100, and a feed hole 130 opened on the top of the box body 100, and a material guide assembly 300 is provided on the inner side wall of the feed box 110.

[0038] A breaker hammer is rotatably connected within the housing 100. The hammer's rotation causes walnuts entering the breaker area to collide with the housing within the housing 100, cracking the shells. The shells and kernels are separated by a fan and sieve. The breaker hammer, fan, and sieve are not shown in the accompanying drawings and are prior art, so their detailed description is omitted.

[0039] Through hole 120 is used to install a fan and a sieve drum. The other side of through hole 120, away from the fan, is used to guide the broken shells. The walnuts to be shelled are introduced into feed box 110, which collects the walnuts into the material guide assembly 300. The material guide assembly 300 uniformly guides the walnuts into the feed hole 130.

[0040] like Figure 3 and 4 As shown, the second shaft 360 is rotatably connected to the inner wall of the feed box 110; the guide wheel 340 is fixed to the outer wall of the second shaft 360. When multiple walnuts are introduced onto the guide wheel 340, the second shaft 360 rotates on the feed box 110, and the rotation of the guide wheel 340 intermittently feeds the multiple walnuts into the feed hole 130.

[0041] The second shaft 360 is connected to the feed box 110 by means of a bearing. The second shaft 360 passes through the guide wheel 340 and is connected to the guide wheel 340 by means of a key connection. The guide wheel 340 is mainly composed of a plurality of baffles, which are arranged regularly. An area is formed between each of the two baffles to limit the positions of multiple walnuts. The second shaft 360 can be driven to rotate by a motor to sequentially introduce the walnuts in different areas into the feed hole 130. By controlling the start and stop of the second shaft 360, the intermittent introduction of walnuts in different areas into the feed hole 130 can be controlled. The number of baffles and the angle between the baffles are determined according to user needs and are not limited to the number of baffles in the figure. The baffle is in the shape of a cuboid or a cube and is made of plastic.

[0042] Specifically, controlling the motor's rotation angle is achieved primarily by selecting the appropriate motor type (stepper motors use pulses to control the step angle, servo motors use closed-loop encoder feedback, and DC motors incorporate limit switches or encoders), building a feedback system (encoder / Hall sensors), and implementing a control algorithm (such as PID control). This is prior art and will not be further elaborated here.

[0043] The top of the box body 100 is provided with a screening component, which is used to screen a plurality of walnuts. The screening component drives the shaft body 2 360 to rotate at the same time. The following describes how the screening component is specifically connected to the shaft body 2 360. The screening component can be screened in the form of a linear vibrating screen or a drum screen. The user can import walnuts of different sizes into the screening component, and the screening component will screen a plurality of walnuts into different sizes, and the sizes can be obtained according to user needs. When the sieved walnuts are imported into the machine through the feed box 110, it is necessary to adjust the height of the breaker hammer so that the breaker hammer is suitable for walnuts of this size (the breaker hammer adjustment method belongs to the prior art and will not be described in detail here). Therefore, a plurality of walnuts can be divided into batches, each batch of each size, to ensure the walnut shelling rate.

[0044] like Figure 4As shown, the inner wall of the feed box 110 is symmetrically provided with a guide block 350, and the outer wall of the guide wheel 340 is in contact with one side of the guide block 350. The top surface of the guide block 350 is in an inclined state relative to the horizontal plane. The guide block 350 is trapezoidal in shape. It is symmetrically arranged on both sides of the feed hole 130 to concentrate the walnuts on the guide wheel 340. Two guide plates 140 are obliquely provided on the inner wall of the feed hole 130. The guide plates 140 are long strips and made of rubber or plastic. The two guide plates 140 are used to limit the rolling of multiple walnuts. Multiple walnuts are arranged between the two guide plates 140 and are inclined by the guide plates 140 to guide the walnuts into the feed hole 130.

[0045] like Figure 3 、 4 As shown in Figure 5, the screening assembly includes: a feed box 200 is fixed to the top of the box body 100 and is connected to the feed box 1 110; a roller 230 is rotatably connected to the inner wall of the feed box 200, and a frame 260 is fixed to the inner wall of the roller 230, and a shaft 1 270 is fixed to one side of the frame 260, and the shaft 1 270 is connected to the shaft 2 360 through a belt assembly.

[0046] The outer wall of the drum 230 has multiple sets of sieve holes (the specific number of sets can be determined based on user needs), which screen walnuts of different sizes. The frame 260 is Y-shaped and is used to transmit the rotation of the drum 230 to the shaft 1 270. The shaft 1 270 and the frame 260 are connected by an interference fit. A belt assembly is installed on one side of the feed box 110. The principle of the belt assembly is similar to that of a synchronous belt and synchronous pulley.

[0047] Specifically, the belt assembly includes: a synchronous wheel 1 310 fixed to one end of the shaft 1 270 ; a synchronous wheel 2 330 fixed to one end of the shaft 2 360 , and the synchronous wheel 2 330 and the synchronous wheel 1 310 are connected through a synchronous belt 320 .

[0048] Four groups of guide rollers 250 are provided and fixed on the second feed box 200 to limit the rotation of the drum 230; the motor 280 is fixed on the second feed box 200, and the output shaft of the motor 280 drives one group of guide rollers 250 to rotate through the transmission assembly 290.

[0049] The guide roller 250 primarily consists of a bearing seat and a rubber roller. The bearing seat is fixed to the second feed box 200 and supports the rubber roller's rotation. The motor 280 drives the transmission assembly 290, which in turn rotates the guide roller 250. The guide roller 250 rubs against the outer wall of the third feed box 210, causing the third feed box 210 to rotate. The transmission assembly 290 operates on the principle of a synchronous belt and synchronous pulley.

[0050] like Figure 4 and5 As shown, a third feed box 210 is fixed to the top of the box body 100. The third feed box 210 is connected to the second feed box 200. A hopper 220 is fixed to the top of the third feed box 210. A discharge port 201 is provided on one side of the second feed box 200. A plate 240 is provided on the inner sidewall of the second feed box 200. The tops of the second feed box 200 and the first feed box 110 are both open.

[0051] The hopper 220 is used to collect multiple walnuts into the feed box three 210, and the feed box three 210 collects multiple walnuts into the drum 230. The drum 230 guides the screened walnuts from the discharge port 201 through the plate 240, and the user can directly import the sorted walnuts into the feed box one 110.

[0052] like Figure 4 and 5 As shown, the output end of the motor 280 passes through the transmission assembly 290 and is fixedly connected to the shaft body 3 410. A transmission box 400 is fixed on one side of the box body 100. The output end of the transmission box 400 is fixedly connected to the screen drum, and the shaft body 3 410 is connected to the transmission box 400.

[0053] The transmission box 400 is provided with the belt assembly mentioned above. When the motor 280 is working, the rotational force is transmitted to the shaft body 410, and the rotational force is transmitted to the screen drum in the prior art by the transmission of the belt assembly, thereby realizing one driving force to drive three functions to work simultaneously, reducing costs. The specific structure of the belt assembly in the transmission box 400 is not given in the accompanying drawings. The principle is the same as above and will not be repeated here.

[0054] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
