Description

Technical Field

[0001] The utility model relates to the technical field of walnut shell crushing, in particular to a shell crusher for walnut oil production. Background Art

[0002] Walnut oil is a vegetable oil squeezed from walnut kernels. It is an edible oil. The oil content of walnuts is as high as 65% to 70%, ranking first among all woody oils. It has the reputation of "oil depot on trees". Modern technology is used to extract its essence. This is the new generation of walnut products - walnut oil. Walnut oil is a natural fruit oil juice made from high-quality walnuts and internationally leading technology. In the international market, walnut oil is known as "Oriental olive oil" and is as popular among consumers as olive oil.

[0003] When producing walnut oil, a shelling machine is needed to first break the shells, and then the walnut kernels are screened out by equipment for subsequent processing. Due to the different sizes of walnuts, the shelling machine may over-crush walnuts of different sizes, causing the walnut kernels to be crushed to a large extent, or fail to crush small walnuts. Therefore, we propose a shelling machine for walnut oil production. Utility Model Content

[0004] The purpose of the utility model is to provide a shell crusher for walnut oil production. By arranging a feeding frame connected to the top of the shell breaking box, and providing an inclined block with a gradually increasing screen opening inside, the walnuts can be graded according to their sizes. The diameter of the shell crushing roller below the corresponding position is gradually reduced so that the crushing spacing is adapted to the walnuts of different grades of the screen opening, which can ensure that walnuts of different sizes can be shelled and avoid excessive squeezing, thereby solving the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a shell crusher for walnut oil production, comprising a shell crushing box and a discharge frame, wherein the discharge frame is arranged in the middle position of the surface of the shell crushing box, the bottom of the discharge frame is connected to the interior of the shell crushing box, and a hopper connected to the interior thereof is connected to the side above the discharge frame, and a discharge port connected to the interior thereof is provided at the bottom of the shell crushing box; an inclined oblique block is fixed inside the discharge frame, the height of the inclined block directly below the hopper is greater than the height of the inclined block on the other side, a through sieve opening is opened on the surface of the inclined block, and the width of the sieve opening gradually increases from high to low on the surface of the inclined block; two shell crushing rollers close to each other are rotatably installed at the front and rear ends of the shell crushing box, and the shell crushing rollers are connected to the stepper motor installed on the outer surface of the shell crushing box at their end, and the diameter of the shell crushing roller gradually decreases in the direction from high to low of the inclined block, thereby realizing that the spacing between adjacent shell crushing rollers gradually increases and changes synchronously with the sieve opening width.

[0006] By adopting the above technical solution, walnuts are dropped from the hopper and enter the discharge frame, where they roll sideways on the inclined surface of the ramp, pass through the sieve openings with gradually increasing opening widths to grade walnuts of different sizes, and then fall downwards. They are squeezed and shelled by shell-breaking rollers with different spacings according to their classification.

[0007] Optionally, a lower frame is fixed inside the shell breaking box below the blanking frame, the lower frame is connected to the blanking frame, and the bottom of the lower frame is placed above the shell crushing rollers.

[0009] Optionally, a plurality of partitions are evenly fixed vertically inside the lower frame, and the upper parts of the partitions extend to contact the bottom surface of the inclined block.

[0010] By adopting the above technical solution, the partition is used to prevent walnuts of different sizes from colliding with each other when the walnuts fall, thereby disrupting the grading again.

[0011] Optionally, an annular plate is fixed around the outer ring of the shell crushing roller at the diameter change position, and the diameters of all the annular plates are the same.

[0012] By adopting the above technical solution, the shell is blocked by the ring plate, which prevents it from sliding to the side with a smaller diameter and a larger shell-crushing distance during extrusion, so that the shell cannot be crushed.

[0013] Optionally, the outer ring of the crushing roller between the ring plates is provided with convex strips, and a plurality of convex strips are evenly arranged.

[0014] By adopting the above technical solution, the convex strips have a toggling effect on the walnuts, ensuring that the walnuts are shelled between the shell-breaking rollers.

[0015] Optionally, the four corners of the bottom of the shell breaking box are supported by supporting feet, and a plurality of supporting feet are provided.

[0016] By adopting the above technical solution, stable support for the shell breaking box is achieved.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0018] 1. The technical solution of the present application is to set a feeding frame connected to the top of the shell breaking box, and to provide an inclined block with a gradually increasing screen opening inside, so that the walnuts can be graded according to their size. The diameter of the shell breaking roller below the corresponding position gradually decreases so that the crushing spacing can adapt to the walnuts of different grades of the screen opening, which can ensure that walnuts of different sizes can be shelled and avoid excessive squeezing.

[0019] 2. The technical solution of the present application is to provide a partition in the lower frame below the inclined block, so as to separate the falling walnuts and prevent the graded walnuts from being mixed together again and disrupted during the falling process.

[0020] 3. The technical solution of the present application is to arrange a ring plate around the outer ring of the crushing roller surface where the diameter changes, so that when the walnut is placed between the shell crushing rollers and squeezed to crush the shell, it is blocked by the ring plate, preventing it from sliding to the side with a smaller diameter and a larger shell crushing distance, making it impossible to be crushed.

[0027] See also Figure 1-4 The utility model provides a technical solution: a shell crusher for walnut oil production, comprising a shell crushing box 1 and a feeding frame 2, the feeding frame 2 is arranged in the middle position of the surface of the shell crushing box 1, and the bottom of the feeding frame 2 is connected to the interior of the shell crushing box 1, and the upper left side of the feeding frame 2 is connected to a hopper 21 connected to the interior thereof, the feeding pipe and the hopper 21 are arranged perpendicular to each other, when walnuts to be shelled are put into the hopper 21, they will fall from the bottom of the hopper 21 into the left interior of the feeding frame 2, the four corners of the bottom of the shell crushing box 1 are supported by supporting legs 12, and a plurality of supporting legs 12 are provided to achieve stable support for the shell crushing box 1.

[0028] An inclined block 3 is fixed inside the discharge frame 2 at an angle. The height of the left side of the inclined block 3 located directly below the hopper 21 is greater than the height of the right side of the inclined block 3, and a through sieve opening 31 is opened on the surface of the inclined block 3. The width of the sieve opening 31 gradually increases from the high point on the left side to the low point on the right side of the surface of the inclined block 3, so that when the walnuts slide from the left side to the right, the small walnuts fall from the sieve opening 31 first, while the large walnuts roll to the right and fall at the position of the sieve opening 31 that can pass through, thereby realizing the grading of the walnuts according to size.

[0029] Two shell crushing rollers 4 are rotatably installed at the front and rear ends of the shell crushing box 1. The two shell crushing rollers 4 are close to and parallel to each other. The shell crushing rollers 4 are connected to the stepper motor 43 installed on the outer surface of the shell crushing box 1 at its right end. When the stepper motor 43 is started, it drives the two shell crushing rollers 4 to rotate clockwise and counterclockwise respectively, and rotates toward the inner side of the upper position. In the direction from high to low of the inclined block 3, that is, from left to right, the diameter of the shell crushing roller 4 gradually decreases and is divided into multiple levels, thereby achieving a gradual increase in the spacing between adjacent shell crushing rollers 4 to ensure that it changes synchronously with the width of the sieve opening 31, so that when the graded walnuts fall, they can be squeezed and crushed by the shell crushing rollers 4 with a suitable spacing therefrom. A discharge port 11 connected to the interior of the shell crushing box 1 is provided at the bottom of the shell crushing box 1, and the shelled walnuts are discharged from the discharge port 11.

[0030] A lower frame 5 is fixed inside the shell breaking box 1 below the blanking frame 2. The lower frame 5 is connected to the blanking frame 2, and the bottom of the lower frame 5 is placed above the shell crushing rollers 4, which can guide the walnuts to between the shell crushing rollers 4 to avoid falling to the outside. In addition, a plurality of partitions 51 are evenly fixed vertically inside the lower frame 5. The upper part of the partition 51 extends to contact the bottom surface of the inclined block 3. The graded walnuts are placed between the partitions 51 and fall downward to avoid the collision of adjacent walnuts of different sizes and being scattered again.

[0031] The outer ring of the crushing roller between the ring plates 42 is provided with ridges 41, and a plurality of ridges 41 are evenly arranged. The ridges 41 have a pushing and pushing effect on the walnuts, so that they are squeezed and shelled. In addition, a ring plate 42 is fixed around the outer ring of the shell crushing roller 4 at the diameter change position. The diameters of all the ring plates 42 are the same, and they can be blocked by the ring plates 42 to prevent them from sliding to the side with a smaller diameter and a larger shell crushing spacing, so that they cannot be shelled.

[0032] When in use, the stepper motor 43 is started, driving the two shell crushing rollers 4 to rotate clockwise and counterclockwise respectively, and rotate toward the inner side of the upper position, and the walnuts to be shelled are put into the hopper 21, and then fall into the discharge frame 2 from the left, and roll to the right on the surface of the inclined block 3. Since the width of the sieve opening 31 on the surface of the inclined block 3 gradually decreases from left to right, the small-sized walnuts among the walnuts will fall downward from the sieve opening 31 on the left, while the large-sized walnuts will slide to the right to a position where they can pass through the sieve opening 31 and then fall downward, thereby realizing the grading of the walnuts by size. Subsequently, walnuts of different sizes are guided downward by the partition 51 and fall between the shell crushing rollers 4 with matching diameters. They can be crushed by the force of the convex strips 41 on the surface of the shell crushing rollers 4 when they rotate inward, and finally discharged from the discharge port 11 at the rear bottom.
