Most of the equipment in the prior art adopts single-stage crushing in processing chemical raw materials, which can only crush larger block raw materials into small pieces, while the smaller pieces of raw materials are less efficient when dissolved by liquid and are still not suitable for subsequent processing. Therefore, the single-stage crushing has a low utilization rate in the market, and a grading chemical raw material crusher is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A grading type chemical raw material crusher comprises a base and a crushing chamber, wherein the crushing chamber is fixedly connected to the upper end of the base, and discharge ports are respectively provided at both ends of the crushing chamber;

The square frame is slidably connected in the crushing chamber, and a filter screen is fixedly connected in the square frame. A slide groove is provided on one side wall of the crushing chamber, and the scraper is slidably connected in the slide groove. A semicircular block is fixedly connected to the lower surface of the scraper. Vertical grooves are respectively provided at both ends of the crushing chamber, and two support rods pass through the vertical grooves and are fixedly connected to the square frame respectively. Two first springs are respectively fixedly connected between the bottom of the vertical groove and the support rod, and one end of the support rod away from the square frame is fixedly connected to a horizontal plate, and a plurality of protrusions are fixedly connected to the upper surface of the horizontal plate;

[0008] The two inner walls of the base are respectively provided with arc grooves, a grinding plate is slidably connected between the two arc grooves, the grinding plate is fixedly connected to the inner wall of the base through a second spring, and both ends of the grinding plate are slidably connected to L-shaped push rods, and the upper end of the push rod is fixedly connected to the cross plate.

[0009] Preferably, the screening component further comprises a reciprocating screw rod, a fixed block is fixedly connected to the crushing chamber, the reciprocating screw rod is rotatably connected to the fixed block, and one end of the scraper is threadedly connected to the reciprocating screw rod.

[0011] Preferably, a servo motor is fixedly connected to the base, a transmission belt is sleeved between the servo motor driving section and the rotating rod, and the transmission belt is sleeved on one end of the reciprocating screw rod.

[0012] Preferably, both ends of the crushing chamber are respectively fixedly connected with lower slide plates which are arranged in an inclined manner, and the two lower slide plates are respectively located at the lower side of the discharge port.

[0013] Preferably, one side of the base is fixedly connected to a collecting chamber, and a discharge port is provided on a side wall of the base close to the collecting chamber.

[0014] Preferably, the scraper is arranged in an L-shape, and one end of the scraper away from the reciprocating screw is located on the upper side of the square frame.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Reference Figure 1-Figure 7 A grading chemical raw material crusher comprises a base 1 and a crushing chamber 8, the crushing chamber 8 is fixedly connected to the upper end of the base 1, and discharge ports are respectively provided at both ends of the crushing chamber 8. When the scraper 15 reciprocates horizontally on the upper side of the filter screen 22, it can push the larger raw materials to the other side of the filter screen 22 and discharge them from the crushing chamber 8 through the discharge port. An inclined slot is provided at the lower end of the crushing chamber 8, and the inclined slot is located at the lower side of the square frame 21. The medium-sized raw materials that are not filtered out by the filter screen 22 and are not pushed to the sides of the crushing chamber 8 by the scraper 15 will slide down the lower side of the grinding plate 13 through the inclined filter screen 22. When the grinding plate 13 moves downward, the raw materials on the lower side can be squeezed, and the extruded raw materials can be ground into fine particles during sliding.

[0032] A screening component is installed in the crushing chamber 8, and the screening component includes a square frame 21, a scraper 15, a support rod 20, and a first spring 18. The square frame 21 is slidably connected in the crushing chamber 8, and the square frame 21 is inclined. A filter screen 22 is fixedly connected in the square frame 21. A slide groove is provided on one side wall of the crushing chamber 8, and the scraper 15 is slidably connected in the slide groove. The slide groove can limit the scraper 15 so that the scraper 15 can only slide back and forth horizontally. A semicircular block 19 is fixedly connected to the lower surface of the scraper 15. The scraper 15 is L-shaped, and one end of the scraper 15 away from the reciprocating screw rod 9 is located on the upper side of the square frame 21. Vertical grooves are respectively provided at both ends of the crushing chamber 8, and two support rods 20 respectively pass through the vertical grooves and are fixedly connected to the square frame 21. Two first springs 18 are respectively fixedly connected between the bottom of the vertical groove and the support rod 20, and the first spring 18 can push the cross plate 11 to move up and reset.

[0033] One end of the support rod 20 away from the square frame 21 is fixedly connected to a cross plate 11, and a plurality of protrusions 10 are fixedly connected to the upper surface of the cross plate 11. The semicircular block 19 is on one side of the protrusion 10, and one end of the semicircular block 19 away from the scraper 15 is slidably connected to the cross plate 11. During the movement of the semicircular block 19 with the scraper 15, the protrusion 10 limits the position of the semicircular block 19 and pushes the cross plate 11 and moves down and stretches the first spring 18. The screening component also includes a reciprocating screw 9. A fixed block 5 is fixedly connected to the crushing chamber 8. The fixed block 5 is used to support the reciprocating screw 9. The reciprocating screw 9 is rotatably connected to the fixed block 5. The outer surface of the contact portion between the reciprocating screw 9 and the fixed block 5 is smoothly set, so that the reciprocating screw 9 can stably rotate on the fixed block 5. One end of the scraper 15 is threadedly connected to the reciprocating screw 9, and the reciprocating screw 9 can drive the scraper 15 to reciprocate horizontally when rotating.

[0034] Arc grooves 24 are respectively provided on the two inner walls of the base 1. The arc grooves 24 are arranged in an arc shape at one end close to the crushing chamber 8, and the other end is arranged horizontally with the bottom wall of the base 1 in an inclined state. Therefore, the grinding plate 13 can first move downward and then slide obliquely to grind the raw materials in the base 1. The grinding plate 13 is slidably connected between the two arc grooves 24. The grinding plate 13 is fixedly connected to the inner wall of the base 1 through a second spring 25. The two ends of the grinding plate 13 are respectively slidably connected to the push rods 12 arranged in an L shape. The upper ends of the push rods 12 are fixedly connected to the cross plate 11. The two ends of the crushing chamber 8 are respectively fixedly connected to the lower slide plates 4 arranged in an inclined manner. The two lower slide plates 4 are respectively located at the lower side of the discharge port. The raw materials ground by the grinding plate 13 can slide into the collecting chamber 14 for collection.

[0035] The crushing chamber 8 is rotatably connected to the first crushing roller 16 and the second crushing roller 17, one end of the first crushing roller 16 is fixedly connected to the first gear 6, the end of the first gear 6 away from the crushing chamber 8 is fixedly connected to the rotating rod, one end of the second crushing roller 17 is fixedly connected to the second gear 7, the first gear 6 is meshingly connected with the second gear 7, and the base 1 is fixedly connected to the servo motor 2, a transmission belt 3 is sleeved between the driving section of the servo motor 2 and the rotating rod, and the transmission belt 3 is sleeved on one end of the reciprocating screw rod 9. The rotation of the servo motor 2 can drive the first gear 6 and the first crushing roller 16 to rotate through the transmission belt 3, the first gear 6 can drive the meshing second gear 7 to rotate, and make the second crushing roller 17 rotate, and at the same time, the rotation of the transmission belt 3 can drive the reciprocating screw rod 9 to rotate.

[0036] In the present invention, when in use, firstly, raw materials are continuously put into the crushing chamber 8 and placed between the first crushing roller 16 and the second crushing roller 17, and the servo motor 2 is driven to rotate the first gear 6 through the transmission belt 3. Since the first gear 6 is meshed and connected with the second gear 7, when the first gear 6 and the fixedly connected first crushing roller 16 rotate clockwise, the second gear 7 and the second crushing roller 17 rotate counterclockwise. The rotation of the first crushing roller 16 and the second crushing roller 17 can crush the raw materials at the upper end of the crushing chamber 8, and the crushed raw materials fall on the filter screen 22. The filter screen 22 can screen the crushed raw materials, so that the fine raw materials can pass through the filter screen 22 and fall into the base 1.

[0037] At the same time, when the servo motor 2 drives the transmission belt 3 to rotate, it can also drive the reciprocating screw 9 to rotate. When the reciprocating screw 9 rotates, it can carry the scraper 15 to move horizontally back and forth in the crushing chamber 8. The scraper 15 can push the larger raw materials on the filter screen 22 to the two sides of the crushing chamber 8, and slide through the discharge ports on both sides to the inclined lower slide plate 4, slide down through the lower slide plate 4 and be collected, so as to be brought into the crushing chamber 8 again for further crushing.

[0038] When the reciprocating screw 9 rotates to drive the scraper 15 to move horizontally, the semicircular block 19 can be limited by the protrusion 10 and push the cross plate 11 and move down and stretch the first spring 18 when the scraper 15 moves. After the semicircular block 19 continues to move and passes over the protrusion 10, the cross plate 11 moves up and resets under the elastic force of the first spring 18. Therefore, as the scraper 15 continues to move, it can cooperate with the first spring 18 to make the cross plate 11 move up and down reciprocatingly. At the same time, the cross plate 11 is fixedly connected to the square frame 21. Therefore, when the cross plate 11 moves up and down, it can drive the square frame 21 and the filter screen 22 to move, thereby speeding up the screening and filtering of the raw materials on the filter screen 22.

[0039] The medium-sized raw materials that are not filtered out by the filter screen 22 and are not pushed to the two sides of the crushing chamber 8 by the scraper 15 will slide down the lower side of the grinding plate 13 through the inclined filter screen 22. As the cross plate 11 moves downward, the push rod 12 can move downward. The push rod 12 pushes the grinding plate 13 to slide in an arc, so that the grinding plate 13 slides downward at an angle in the base 1. When the grinding plate 13 moves downward, the raw materials on the lower side can be squeezed, and the squeezed raw materials can be ground into fine particles when sliding. When the cross plate 11 moves upward, the push rod 12 drives the mask grinding plate 13 to move upward and reset, and the ground raw materials will slide into the collecting chamber 14 for subsequent use.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
