Description

Technical Field

[0001] The utility model relates to the technical field of walnut processing, in particular to a walnut feeding structure and a walnut shelling device. Background Art

[0002] Walnuts are rich in nutrition, have a unique taste, and have certain medicinal value. They are becoming increasingly popular and loved by people. Walnuts are an important raw material for the edible vegetable oil industry. Walnut oil can be used to make margarine, shortening, salad oil, blending oil, etc. It can also be used as an industrial raw material. In addition to being edible after simple processing, walnuts can also be processed into various foods and health products.

[0003] Many existing walnut processing methods still use hammers to manually crack the shells. The manual shelling method not only has low processing efficiency and high cost, but also cannot ensure the hygiene of food, and there is a potential threat to the health of consumers.

[0004] At present, in addition to the manual method of removing the kernel, there are several methods for walnut shelling and kernel removal: centrifugal collision shelling, chemical corrosion, vacuum shelling and kernel removal, ultrasonic shelling, and mechanical shelling. In the first method, the centrifuged walnuts hit the wall at high speed to deform the shell until it breaks, but a lot of broken kernels are produced after shelling, so the method is not ideal; in the second method, the dosage of the agent is not easy to control in actual operation, the walnut kernel is easily corroded, and improper handling will cause environmental pollution, so the method is rarely used; in the third and fourth methods, the equipment is expensive, the shelling cost is too high, and the shelling effect is not ideal. In the fifth method, the equipment is simple and the cost is low, and the shelling effect can be improved by improving the component structure, so this method has been explored and applied more.

[0005] Publication No. CN114903182A provides a mechanized processing method for shelling and removing the kernel of Yangbi bubble walnuts. First, processing is performed on the top of the walnut body along the suture line of the nut body to remove the hard shell top structure that binds the kernel of the nut, and a first opening is obtained in the processing area to expose the outer wall of the kernel; processing is performed on the bottom of the Yangbi bubble walnut nut to obtain a second opening in the processing area to release the structure that fixes the kernel at the bottom of the nut and expose the outer wall of the kernel; perpendicular to the XY plane of the nut along the Z-axis direction, the nut is squeezed with a blade along the plane formed by the perpendicular suture line to obtain two halves of the nut body, and the obtained two halves of the nut body are put into a vibrating screen for vibration, and the kernel and the shell of the nut are separated after vibration.

[0006] For this processing method, the walnuts need to be cut one by one. If the efficiency of manual operation is a bit low, in order to achieve mechanization, even if automatic loading and unloading are adopted, how to ensure that only one walnut is loaded each time is a problem. Utility Model Content

[0007] The utility model aims at the problem of how to ensure that all the feed materials are one walnut to ensure that each walnut can be cut and processed when the walnuts are shelled, and provides a walnut feeding structure and a walnut shelling device.

[0008] In order to achieve the above-mentioned utility model purpose, the utility model provides the following technical solutions:

[0009] On the one hand, the present application provides a walnut feeding structure, including a shell, a first spiral roller, a second spiral roller and a first transmission mechanism, the first spiral roller and the second spiral roller are located in the shell, the first transmission mechanism is used to drive the first spiral roller and the second spiral roller to rotate, the shell is connected to a feed hopper, and a discharge hole is provided at the bottom of the shell away from the feed hopper; baffles are provided on both sides of the top of the shell; the first transmission mechanism includes a first transmission motor, a driving gear and a driven gear, the first spiral roller is connected to the driving gear, the second spiral roller is connected to the driven gear, the inner side of the first spiral roller rotates from the direction of the discharge hole toward the feeding direction, and the inner side of the second spiral roller rotates from the direction of the discharge hole toward the feeding direction.

[0010] The present application uses the first spiral roller and the second spiral roller to adjust the distance between the first spiral roller and the second spiral roller, so that only one walnut can move forward each time when it rotates. When it reaches the discharge hole, it is ensured that only one walnut enters the next step each time, which can ensure easy grasping during subsequent cutting.

[0011] Preferably, the first spiral roller and the second spiral roller are symmetrically arranged. Such a design makes the first spiral roller and the second spiral roller rotate synchronously, which can effectively ensure the advancement of the walnuts.

[0012] Preferably, the first spiral roller rotates clockwise, and the second spiral roller rotates counterclockwise. That is to say, the inner sides of the first spiral roller and the second spiral roller are guaranteed to be upward during rotation, and the feed hopper is located on one side of the ends of the first spiral roller and the second spiral roller. The walnuts enter the gap between the first spiral roller and the second spiral roller through the feed hopper. If multiple walnuts are stuck at the first spiral roller and the second spiral roller at the same time, since the first spiral roller and the second spiral roller rotate relatively upward, the position of the walnuts can be adjusted to ensure that they will not be stuck.

[0013] Preferably, the first transmission mechanism includes a first transmission motor, a driving gear and a driven gear, the first spiral roller is connected to the driving gear, the second spiral roller is connected to the driven gear, the output shaft of the first transmission motor is connected to the driving gear through a first belt, the driven gear is meshed with the driving gear, and the first transmission motor drives the driving gear to rotate clockwise by the positive rotation. The first transmission motor drives the driving gear to rotate, and the driven gear is meshed with the driving gear, thereby realizing the rotation of the first spiral roller and the second spiral roller.

[0014] Preferably, baffles are provided on both sides of the top of the shell, and the baffles are located above the first spiral roller and the second spiral roller, so as to prevent the walnuts from being squeezed out when the first spiral roller and the second spiral roller rotate.

[0015] Preferably, first mounting plates are provided on both sides of the shell, and the first transmission mechanism is mounted on the first mounting plates. The shell is supported by the first mounting plates on both sides of the shell, so that the walnuts can fall out of the discharge hole smoothly.

[0016] Preferably, a second transmission mechanism is provided at the lower part of the housing, the second transmission mechanism is cross-arranged with the housing, the second transmission mechanism is located below the discharge hole, the second transmission mechanism includes a second mounting plate, a second belt and a second transmission motor, a driving shaft and a driven shaft are mounted on the second mounting plate, the second transmission motor is connected to the driven shaft, and the second belt is sleeved on the driving shaft and the driven shaft. After the walnuts fall out of the discharge hole, they fall onto the second belt, and the second belt transports the walnuts to the corresponding position.

[0017] Preferably, the second belt is multiple, and the walnut is oval, and after falling, it basically contacts the second belt at the place with a gap in the middle, which will form a point contact with a relatively small contact area. The friction between the walnut and the second belt is small, so it is possible that the second belt rotates forward while the walnut does not move forward. Therefore, the present application designs the second belt to be multiple relatively narrow, and the part that contacts the middle part of the walnut will be concave, and the second belt next to it will contact other parts of the walnut, thus increasing the contact area between the entire second belt and the walnut, and the second belt can smoothly drive the walnut forward.

[0018] Preferably, multiple second belts are evenly arranged, and a sensor can be set near the discharge hole to detect whether there is an empty belt. If there is an empty belt, the first transmission motor continues to rotate until the sensor detects the walnut, which can improve the efficiency of subsequent operations.

[0019] On the other hand, the present application provides a walnut shelling device, including the walnut feeding structure described above.

[0020] Compared with the prior art, the utility model has the following beneficial effects: the application designs the first spiral roller, the second spiral roller and the shell, so that there is only one walnut entering between the first spiral roller, the second spiral roller and the shell, and controls the rotation direction of the first spiral roller and the second spiral roller, so that the walnut will not be stuck and can move forward in an orderly manner, and the walnut can be smoothly transported to the set position through the second transmission mechanism, and the spacing between the walnuts falling on the second belt can be constant by controlling the rotation speed of the first transmission motor and the rotation speed of the second transmission motor. Through the walnut feeding mechanism provided by the application, it can be ensured that the cutting efficiency is higher in automated production. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The utility model is described in detail below in conjunction with the accompanying drawings.

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] In the description of the present utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection of two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0031] like Figures 1 to 5 As shown, the present application provides a walnut feeding structure, including a shell 1, first mounting plates 13 are installed on both sides of the shell 1, the first mounting plates 13 make the shell 1 suspended, bearings are installed on both sides of the shell 1, a first spiral roller 2 and a second spiral roller 3 are installed on the bearings, a first transmission mechanism 4 is installed on one side of the shell 1, and a feed hopper is installed on the other side.

[0032] like Figure 3 As shown, the lead P of the first spiral roller 2 and the second spiral roller 3 and the distance between the first spiral roller 2 and the second spiral roller 3 are controlled so that only one walnut can be placed between the first spiral roller 2 and the second spiral roller 3. The distance between the first spiral roller 2 and the second spiral roller 3 is larger than the size of one walnut and smaller than the size of two walnuts. The size of the walnut mentioned in this application is the general size of walnuts on the market.

[0033] The first spiral roller 2 and the second spiral roller 3 are located in the shell 1, the first transmission mechanism 4 is used to drive the first spiral roller 2 and the second spiral roller 3 to rotate, and a discharge hole 11 is provided at the bottom of the shell 1 away from the feed hopper.

[0034] like Figure 2 As shown, the first transmission mechanism 4 includes a first transmission motor 41, a driving gear 42 and a driven gear 43, the first spiral roller 2 is connected to the driving gear 42, and the second spiral roller 3 is connected to the driven gear 43. The output shaft of the first transmission motor 41 is connected to the driving gear 42 through a first belt 44, and the driven gear 43 is meshed with the driving gear 42.

[0035] A U-shaped connecting plate is installed on the first mounting plate 13 , and the first transmission motor 41 is installed on the connecting plate. The connecting plate wraps the driving gear 42 and the driven gear 43 , which not only serves to install the first transmission motor 41 , but also serves to protect the driving gear 42 and the driven gear 43 .

[0036] like Figure 3 As shown, the first spiral roller 2 and the second spiral roller 3 are symmetrically arranged, and the first spiral roller 2 rotates clockwise, and the second spiral roller 3 rotates counterclockwise. Figure 3 From the right side, the first transmission motor 41 rotates forward to drive the driving gear 42 to rotate clockwise, and the rotation direction is as follows: Figure 4 That is to say, the inner sides of the first spiral roller 2 and the second spiral roller 3 are both facing upwards. If the walnuts entering between the first spiral roller 2 and the second spiral roller 3 from the feed hopper are stuck, the position of the walnuts can be adjusted. If the inner sides of the first spiral roller 2 and the second spiral roller 3 are facing downwards, the walnuts may be stuck between the first spiral roller 2, the second spiral roller 3 and the shell 1.

[0037] Baffles 12 are provided on both sides of the top of the shell 1. The baffles 12 are horizontal and are used to prevent walnuts from jumping out from above. The baffles 12 are equivalent to partially covering the first spiral roller 2 and the second spiral roller 3.

[0038] A second transmission mechanism 5 is disposed at the lower part of the housing 1. The second transmission mechanism 5 is arranged crosswise with the housing 1. In this embodiment, the second transmission mechanism 5 and the housing 1 are arranged vertically. The second transmission mechanism 5 is located below the discharge hole 11. Due to the shape of the walnut, when the walnut falls onto the second transmission mechanism 5, the middle suture line is generally at the bottom.

[0039] The second transmission mechanism 5 comprises a second mounting plate 51, a second belt 52 and a second transmission motor. A driving shaft and a driven shaft are mounted on the second mounting plate 51. The second transmission motor is connected to the driving shaft. The second belt 52 is sleeved on the driving shaft and the driven shaft. The second belt 52 drives the driving shaft to rotate, thereby driving the second belt 52 to rotate.

[0040] Since the walnut falls on the second belt 52 with the middle suture line at the bottom and the walnuts on both sides of the suture line are upward arcs, the contact between the walnut and the second belt 52 is less, and there may be only one point, which will result in a small contact area, and the second belt 52 moves forward while the walnut does not move. Therefore, in order to prevent this from happening, the present application designs the second belt 52 into multiple pieces, and the multiple second belts 52 are evenly arranged, and the housing 1 is provided with a sensor near the discharge hole 11. In this way, after the walnut falls on the second belt 52, the middle suture line contacts the second belt 52, the middle part is concave downward, and the two ends of the walnut contact the second belt 52, thereby increasing the contact area between the walnut and the second belt 52, and the second belt 52 can smoothly drive the walnut forward. If there are multiple second belts 52, a card slot is provided on the active rotating shaft and the driven rotating shaft for each second belt 52 to prevent the second belt 52 from slipping and falling off with the active rotating shaft and the driven rotating shaft after the second belt 52 rotates.

[0041] On the other hand, the present application also provides a walnut shelling device, including the walnut feeding structure described above.

[0042] Working process: the walnuts pass through the feed hopper into the hole between the first spiral roller 2 and the second spiral roller 3 and then fall onto the shell 1. The first transmission motor 41 rotates forward to drive the first spiral roller 2 and the second spiral roller 3 to rotate, thereby rotating the walnuts forward. When the walnuts enter the discharge hole 11, the walnuts fall from the discharge hole 11 onto the second belt 52. The second transmission motor drives the walnuts forward through the belt and enters the next cutting process.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
