[0026] like Figure 1-Figure 8As shown, the utility model provides a technical solution: a crusher with a screening structure, comprising a machine body 1, wherein the inner wall of the machine body 1 is provided with a plurality of sorting slots 2, and the walnuts can be arranged from the right side of the machine body 1 to the left side of the machine body 1 in order from small to large by means of the sorting rods 71 ​​and the plurality of sorting slots 2, and a hopper 3 is fixedly installed on the top of the machine body 1, and the walnuts are first poured into the interior of the hopper 3, and at this time the walnuts will fall downwards to between the two groups of sorting rods 71, and are fed to the machine body 1 through the two groups of sorting rods 71. The left side of the machine body 1 rolls, and a lifting cylinder 4 is fixedly installed on the outer wall of the machine body 1. A baffle 5 is slidably connected to the outer wall of the machine body 1. The piston end of the lifting cylinder 4 is fixedly installed at the bottom of the baffle 5. The lifting cylinder 4 is started to drive the baffle 5 to move downward, so that the baffle 5 is separated from the crushing block 64, and the sorting tank 2 is exposed as a whole. At this time, the walnuts after shelling in the sorting tank 2 can be taken out, and a slide plate 61 is slidably connected to the inner wall of the machine body 1. A crushing cylinder 62 is fixedly installed at the bottom of the slide plate 61. The piston end of the crushing cylinder 62 is fixedly installed The cross plate 63 is fixedly provided with a crushing block 64 matching the sorting slot 2 at the bottom of the cross plate 63. The crushing cylinder 62 is repeatedly started, so that the crushing cylinder 62 drives the cross plate 63 to move up and down, and then the cross plate 63 drives multiple groups of crushing blocks 64 to move up and down, so that the crushing blocks 64 can punch the walnuts inside the sorting slot 2 to break the shells of the walnuts. The crushing blocks 64 are arranged from short to high from left to right, and are arranged at the bottom of the cross plate 63 in increasing order. Through the up and down reciprocating movement of the cross plate 63, the multiple groups of crushing blocks 64 located at the bottom of the cross plate 63 have different heights. Therefore, the downward impact strokes of the multiple groups of crushing blocks 64 are different, which is convenient for uniformly punching walnuts of different sizes and improving the shell breaking quality of walnuts. A screening mechanism 7 for screening walnut sizes is arranged on the machine body 1. By setting the screening mechanism 7, the walnuts can be crushed separately according to their sizes, and the shell breaking quality of the walnuts can be improved. An auxiliary mechanism 8 is arranged on the machine body 1. By setting the auxiliary mechanism 8, the two groups of sorting rods 71 ​​can be quickly positioned according to the maximum size of the walnuts.

[0027] The screening mechanism 7 comprises a sorting rod 71, a motor 72, a slider 73, a stop rod 74, a bidirectional screw rod 75, a threaded block 76, a sleeve 77 and a connecting rod 78; one end of the sorting rod 71 is hinged to the inner wall of the machine body 1, and the outer wall of the other end of the sorting rod 71 is slidably connected with a sleeve 77. There are two groups of sorting rods 71. The two groups of sorting rods 71 ​​are mirror-imaged on both sides of the hopper 3 with the hopper 3 as the central axis. The outer wall of the sorting rod 71 is fixedly mounted with a stop rod 74. The sorting rod 71 is tiltedly arranged inside the machine body 1, and there is an angle between the two groups of sorting rods 71. The farther the sorting rod 71 is from the hopper 3, the larger the angle is. First, pour the walnuts into the hopper 3. At this time, the walnuts will fall down between the two groups of sorting rods 71 ​​and roll to the left side of the machine body 1 through the two groups of sorting rods 71. At this time, since there is an angle between the two groups of sorting rods 71, and the farther the two groups of sorting rods 71 ​​are from the hopper 3, the larger the angle is, so during the rolling process, the walnuts will fall down to the inside of the sorting slot 2 in order from small to large. The end of the sorting rod 71 located in the hopper 3 is higher than the end located in the sleeve 77, and the opening at the bottom of the hopper 3 is located at Between the two groups of selection rods 71, the motor 72 is fixedly mounted on the outer wall of the left side of the machine body 1, and a bidirectional screw rod 75 is fixedly mounted on the output end of the motor 72. The outer wall of the bidirectional screw rod 75 is threadedly connected with two groups of threaded blocks 76. The motor 72 drives the bidirectional screw rod 75 to rotate, and the rotation of the bidirectional screw rod 75 can drive the two groups of threaded blocks 76 threadedly connected thereto to move synchronously in opposite directions. The bottom of the threaded block 76 is rotatably connected to the top of the sleeve 77. The two groups of threaded blocks 76 move synchronously in opposite directions, and the sleeve 77 can drive the two groups of selection rods 71 ​​to move in opposite directions. The two groups of selecting rods 71 ​​can be swung synchronously in opposite directions to adjust the angle between them. The slider 73 is threadedly connected to the outer wall of the bidirectional screw rod 75. The top of the slider 73 is hinged with a connecting rod 78. The end of the connecting rod 78 away from the slider 73 is hinged to the side wall of the slide plate 61. When the two groups of selecting rods 71 ​​are adjusting the size of the angle, the slider 73 cooperates with the connecting rod 78 to drive the slide plate 61 to slide. At the same time, in cooperation with the crushing cylinder 62 and the cross plate 63, the distance between the crushing block 64 and the sorting slot 2 can be adjusted, so that the crushing block 64 can fully shell the walnuts.

[0028] The auxiliary mechanism 8 includes a scale 81, an L rod 82, and a pointer 83; the scale 81 is fixedly installed on the outer wall of the body 1, the side wall of the threaded block 76 is fixedly installed with the L rod 82, and the end of the L rod 82 away from the threaded block 76 is fixedly installed with a pointer 83. When the two groups of threaded blocks 76 cooperate with the sleeve 77 to adjust the angle between the two groups of selection rods 71, the maximum distance between the two groups of selection rods 71 ​​can be observed through the set scale 81, L rod 82, and pointer 83, which is convenient for quickly positioning the two groups of selection rods 71 ​​according to the maximum size of the walnut.

[0029] Working principle: first pour the walnuts into the hopper 3, then the walnuts will fall down between the two groups of sorting rods 71, and roll to the left side of the machine body 1 through the two groups of sorting rods 71. At this time, since there is an angle between the two groups of sorting rods 71, and the farther the two groups of sorting rods 71 ​​are from the hopper 3, the larger the angle is, the walnuts will fall down to the inside of the sorting slot 2 in order from small to large during the rolling process. By setting up multiple groups of sorting slots 2, the size of the walnuts can be arranged from the right side of the machine body 1 to the left side of the machine body 1 in order from small to large, and the distance between the crushing block 64 on the left side of the machine body 1 and the sorting slot 2 is the largest, so that the larger walnuts can smoothly roll to the bottom of the sorting slot 2 and be placed under the crushing block 64. After the walnuts have been sorted by the two-group sorting rods 71 ​​and the multi-group sorting slots 2, the crushing cylinder 62 is started again to drive the cross plate 63 to move up and down, and then the cross plate 63 drives the multiple groups of crushing blocks 64 to move up and down, so that the crushing blocks 64 can punch the walnuts inside the sorting slot 2 to break the shells of the walnuts. Through the up and down reciprocating movement of the cross plate 63, the multiple groups of crushing blocks 64 located at the bottom of the cross plate 63 have different heights, so the downward impact strokes of the multiple groups of crushing blocks 64 are different, which is convenient for uniformly punching walnuts of different sizes and improving the shelling quality of the walnuts. After the shelling is completed, the crushing cylinder 62 is closed, and the lifting cylinder 4 is started to drive the baffle 5 to move downward, so that the baffle 5 is separated from the crushing block 64, and the sorting slot 2 is closed. The slot 2 is exposed as a whole, and the shelled walnuts in the sorting slot 2 can be taken out at this time. The motor 72 is started to drive the bidirectional screw rod 75 to rotate. The rotation of the bidirectional screw rod 75 can drive the two groups of threaded blocks 76 threadedly connected thereto to move synchronously in opposite directions. At the same time, the sleeve 77 can drive the two groups of sorting rods 71 ​​to swing synchronously in opposite directions. The angle between the two groups of sorting rods 71 ​​can be adjusted by the swing of the two groups of sorting rods 71. At the same time, the L rod 82, the pointer 83, and the scale 81 can be used to observe the maximum spacing between the two groups of sorting rods 71. The two groups of sorting rods 71 ​​can be adjusted to a suitable spacing according to the size of the largest walnut. When the two groups of threaded blocks 76 are close to each other, the sleeve 77 can drive the two groups of sorting rods 71 ​​to move synchronously. At the same time, the slide block 73 and the connecting rod 78 can pull the slide plate 61 downward, so that the slide plate 61 drives the crushing cylinder 62 to move downward, and the crushing cylinder 62 drives the cross plate 63 and the multiple groups of crushing blocks 64 to move downward, so that the distance between the bottom of the crushing block 64 and the inner wall of the sorting trough 2 is gradually reduced. By reducing the angle between the two groups of sorting rods 71, small walnuts can be sorted. At the same time, the distance between the crushing block 64 and the sorting trough 2 is reduced, so that the crushing block 64 can fully shell the walnuts. When the two groups of threaded blocks 76 move away from each other, the sleeve 77 can drive the two groups of sorting rods 71 ​​to move away from each other, so that the angle between the two groups of sorting rods 71 ​​gradually increases.At the same time, the slider 73 and the connecting rod 78 can push the slide plate 61 upwards, and the crushing cylinder 62 and the cross plate 63 can gradually increase the distance between the bottom of the crushing block 64 and the inner wall of the sorting trough 2. By expanding the angle between the two groups of sorting rods 71, large walnuts can be sorted. At the same time, the distance between the crushing block 64 and the sorting trough 2 is increased, so that the crushing block 64 can break the shell of large walnuts to avoid the walnut kernel being crushed due to the close distance.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
