Description

Technical Field

[0001] This utility model belongs to the technical field of nut opening machines, specifically a manual nut extrusion opening machine. Background Technology

[0002] Nuts are a type of fruit of plants, usually with a hard shell enclosing edible seeds, such as walnuts, almonds, cashews, and hazelnuts. They are rich in unsaturated fatty acids, protein, dietary fiber, vitamins (such as vitamin E and B vitamins) and minerals (such as magnesium, zinc, and potassium). They are foods with high nutrient density and help maintain cardiovascular health, regulate blood lipids, provide antioxidants, and promote brain function.

[0003] Currently, existing methods for cracking nuts include using hand pliers to clamp them one by one, which requires repeated adjustments to the clamping angle to break the shell; and using a hammer to crack the shell, which requires multiple attempts to determine the appropriate force. These methods are inefficient and labor-intensive. Furthermore, when the angle or position of force is off, the nuts can easily slip or bounce off the tools, scattering on the ground and contaminating the ground with dust, negatively impacting food safety. In addition, for the elderly and minors, these methods are difficult to control the force applied, which can easily cause nuts to fly and may also cause accidental injury from the tools, posing significant safety hazards. Therefore, these methods need to be improved. Utility Model Content

[0004] The purpose of this invention is to address the above problems by providing a manual nut-opening machine that is easy to use and can open shells in batches.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a manual nut extrusion and opening machine, comprising a base plate, side plates fixedly installed on the front and rear sides of the top of the base plate, an installation block movably connected to the right side of the top of the base plate, a toothed plate fixedly connected to the left side of the installation block, a round shaft movably sleeved between the side plates, a round sleeve fixedly sleeved on the outer surface of the round shaft, an eccentric round block fixedly sleeved on the outer surface of the round sleeve, rotating plates fixedly sleeved on the front and rear sides of the outer surface of the round shaft, a connecting plate fixedly connected to the left end of the rotating plate, a round rod fixedly connected to the left end of the connecting plate, an anti-slip sleeve fixedly sleeved on the left side of the outer surface of the round rod, and a groove opened on the left side of the bottom of the base plate.

[0006] As a preferred embodiment of this utility model, a limiting groove is formed inside the side plate, and a limiting block is movably installed inside the limiting groove. The inner side of the limiting block is fixedly connected to the outer surface of the mounting block.

[0007] As a preferred embodiment of this utility model, a double-threaded rod located on the right side of the mounting block is movably sleeved inside the side plate. Circular plates are fixedly sleeved on both the front and rear sides of the outer surface of the double-threaded rod, and the outer surface of the circular plates is movably connected to the inner surface of the side plate.

[0008] As a preferred embodiment of this utility model, a knob located on the front side of the outer surface of the double threaded rod is fixedly sleeved, and the outer surface of the knob is provided with anti-slip texture.

[0009] As a preferred embodiment of this utility model, the front and rear sides of the outer surface of the double threaded rod are threaded with movable blocks, and the top and bottom left sides of the movable blocks are hinged with hinge rods, the left end of the hinge rods being hinged to the right side of the mounting block.

[0010] As a preferred embodiment of this utility model, a horizontal plate is movably sleeved inside the right end of the movable block, and both the front and rear ends of the horizontal plate are fixedly connected to the inner surface of the side plate.

[0011] As a preferred embodiment of this utility model, a back plate is fixedly installed on the right side of the side plate, and a top plate is fixedly installed on the right side of the top of the side plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up a toothed plate, a round shaft, an eccentric round block, and a round rod, allows the operator to place the nut on the left side of the toothed plate, then hold the anti-slip sleeve and rotate the round rod upwards. This causes the round rod to drive the round shaft to rotate through the connecting plate and the rotating plate, which in turn causes the eccentric round block to rotate around the round shaft. During the rotation, the nut on the left side of the toothed plate is gradually squeezed, making the nut come into close contact with the toothed plate and applying pressure to the nut with the eccentric round block, thereby achieving safe and fast opening of the nut.

[0013] 2. This utility model, by setting up a double-threaded rod, a moving block, and a hinge rod, allows for the following: when the nuts are too large to be placed on the left side of the toothed plate, or when the nuts are too small to effectively apply pressure to the nuts during the rotation of the eccentric block, the double-threaded rod can be rotated to cause the two moving blocks to move in opposite directions or towards each other. In turn, the hinge rod causes the mounting block to move to the left or right under the limiting action of the limiting block, thereby adjusting the position of the toothed plate and enabling the processing of nuts of different sizes.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 5 As shown, this utility model provides a manual nut extrusion and opening machine, including a base plate 1, side plates 2 fixedly installed on the front and rear sides of the top of the base plate 1, an installation block 3 movably connected to the right side of the top of the base plate 1, a toothed plate 4 fixedly connected to the left side of the installation block 3, a round shaft 5 movably sleeved between the side plates 2, a round sleeve 6 fixedly sleeved on the outer surface of the round shaft 5, an eccentric round block 7 fixedly sleeved on the outer surface of the round sleeve 6, a rotating plate 8 fixedly sleeved on the front and rear sides of the outer surface of the round shaft 5, a connecting plate 9 fixedly connected to the left end of the rotating plate 8, a round rod 10 fixedly connected to the left end of the connecting plate 9, an anti-slip sleeve 11 fixedly sleeved on the left side of the outer surface of the round rod 10, and a slot 23 opened on the left side of the bottom of the base plate 1.

[0018] The slot 23 is vertically aligned with the eccentric block 7, so that the eccentric block 7 can avoid being blocked by the base plate 1 when rotating around the circular shaft 5. The operator places the nut on the left side of the toothed plate 4, and then rotates the circular rod 10 upward, thereby driving the circular shaft 5 to rotate through the connecting plate 9 and the rotating plate 8. The circular shaft 5 drives the eccentric block 7 to rotate around the circular shaft 5 through the circular sleeve 6, thereby causing the eccentric block 7 to gradually squeeze the nut, so that the nut fits against the toothed plate 4, thereby squeezing the nut open.

[0019] The side plate 2 has a limiting groove 12 inside, and a limiting block 13 is movably installed inside the limiting groove 12. The inner side of the limiting block 13 is fixedly connected to the outer surface of the mounting block 3.

[0020] By setting the limit block 13, the mounting block 3 can be limited, making the mounting block 3 move more stably left and right, and preventing the mounting block 3 from moving upward and deviating.

[0021] The side plate 2 is movably sleeved with a double threaded rod 14 located on the right side of the mounting block 3. The front and rear sides of the outer surface of the double threaded rod 14 are fixedly sleeved with circular pieces 15, and the outer surface of the circular pieces 15 is movably connected to the inner surface of the side plate 2.

[0022] The threads on the front and rear sides of the outer surface of the double threaded rod 14 are in opposite directions. Due to the design of the disc 15, the double threaded rod 14 can be restricted, thereby preventing the double threaded rod 14 from detaching from the interior of the side plate 2.

[0023] Among them, a knob 16 located on the front side of the side plate 2 is fixedly sleeved on the front side of the outer surface of the double threaded rod 14, and the outer surface of the knob 16 is provided with anti-slip texture 17.

[0024] The operator can rotate the knob 16 to rotate the double threaded rod 14. The anti-slip texture 17 is designed to prevent slipping, making it more stable for the operator to rotate the knob 16.

[0025] Among them, the front and rear sides of the outer surface of the double threaded rod 14 are threaded with moving blocks 18, and the top and bottom left sides of the moving blocks 18 are hinged with hinge rods 19, and the left end of the hinge rods 19 is hinged to the right side of the mounting block 3.

[0026] When the two moving blocks 18 move toward each other, the mounting block 3 will be driven to move to the right under the limiting action of the limiting groove 12 through the hinge rod 19, so that the larger nut can be placed to the left side of the toothed plate 4.

[0027] Among them, the right end of the movable block 18 is internally fitted with a horizontal plate 21, and both the front and rear ends of the horizontal plate 21 are fixedly connected to the inner surface of the side plate 2.

[0028] By setting the horizontal plate 21, the moving block 18 is limited, preventing the moving block 18 from rotating when the double threaded rod 14 rotates, so that the moving block 18 can move stably in the horizontal direction.

[0029] A back plate 20 is fixedly installed on the right side of the side plate 2, and a top plate 22 is fixedly installed on the right side of the top of the side plate 2.

[0030] The design of the back plate 20 and the top plate 22 can protect the double threaded rod 14 and prevent nut shell fragments from splashing into the location of the double threaded rod 14 and affecting the rotation of the double threaded rod 14 or the movement of the moving block 18.

[0031] Working principle and usage process of this utility model: The operator places the nut on the left side of the toothed plate 4, and then rotates the round rod 10 upward by holding the anti-slip sleeve 11. This causes the rotating plate 8 to rotate through the connecting plate 9, which in turn causes the round shaft 5 and the round sleeve 6 to rotate the eccentric block 7. At this time, the eccentric block 7 will rotate around the round shaft 5 as the axis, thereby squeezing and pushing the nut so that the nut is pressed tightly against the left side of the toothed plate 4. As the eccentric block 7 continues to rotate, it will apply pressure to the nut, thereby achieving the opening process of the nut.

[0032] When a nut is too large to fit on the left side of the toothed plate 4, the knob 16 can be rotated to cause the double threaded rod 14 to move the two moving blocks 18 toward each other. This causes the hinge rod 19 to move the mounting block 3 to the right under the limiting action of the limiting block 13, thereby increasing the space between the toothed plate 4 and the eccentric block 7, allowing larger nuts to fit. When a nut is too small for the eccentric block 7 to effectively compress, the knob 16 can be rotated in the opposite direction to move the mounting block 3 to the left, reducing the space between the toothed plate 4 and the eccentric block 7. In this case, the eccentric block 7 can effectively apply pressure to smaller nuts, improving the flexibility of the device.
