A supporting groove 14 is provided on the inner wall of one side of the first receiving platform 10 and the second receiving platform 11 at a horizontal side position near the weighing plate 13. The bottom of the crusher body 1 is fixedly connected to the crusher body support frame 15 by bolts near the outer side position of the weighing discharge box 9. An inner lining plate 16 is provided on the inner wall of one side of the crusher body 1, and a crushing hammer 17 is connected to the inner rotation of the crusher body 1. An impact plate 18 and a screen 19 are provided on the inner wall of one side of the inner lining plate 16. The impact plate 18 is located on one side of the screen 19. A PLC controller 20 is fixedly connected to the outer wall of one side of the crusher body support frame 15 by bolts. When adjusting the feeding amount, the raw materials to be crushed are poured into the material storage hopper 4, and the material storage hopper 4 stores the raw materials. At this time, the stepper reduction motor 5 does not work, and the electric push rod 12 on the first receiving platform 10 is energized and works.

The crusher body 1 crushes the raw materials through the impact of the rotating crushing hammer 17 and the collision of the raw materials with the impact plate 18. Since the first weighing and loading bins 2 and 3 are provided, the feeding interval between the first weighing and loading bins 2 and 3 is set by the timing timer 6. This ensures that when the first weighing and loading bin 2 is loading, the second weighing and loading bin 3 is performing quantitative weighing. This cycle ensures that there is always raw materials entering the crusher body 1, thus ensuring that the crusher body 1 fully crushes the raw materials and preventing the crushing hammer 17 in the crusher body 1 from idling.

[0027] The present invention further has the following features: the first weighing loading box 2 and the second weighing loading box 3 are both connected to the crusher body 1 , so that the weighed raw materials in the first weighing loading box 2 and the second weighing loading box 3 can enter the crusher body 1 .

[0033] The present invention further has the following features: a screen 19 is embedded in the inner lining plate 16 , a feed opening is provided at the bottom of the grinder body 1 near the lower portion of the screen 19 , and the raw materials meeting the crushing size are screened out through the screen 19 .

[0034] The present invention further has the advantage that the breaker hammer 17 is driven to rotate by an external motor and a pulley assembly, ensuring that the breaker hammer 17 can rotate at a high speed, thereby enabling the breaker hammer 17 to crush and impact the raw materials.

[0035] The present invention further comprises: a pressure sensor is provided inside the weighing plate 13; the stepping reduction motor 5, the timing timer 6, the electric push rod 12 and the pressure sensor are all electrically connected to the PLC controller 20; and by setting the control program of the PLC controller 20, the stepping reduction motor 5 and the electric push rod 12 can be controlled according to the input information of the timing timer 6 and the pressure sensor.

[0036] Example 2: Please refer to Figure 1 、 Figure 6 and Figure 7 The present invention provides a technical solution: a crushing device with a material amount adjustment mechanism, comprising a crusher body 1, a weighing discharge box 9 is fixedly connected to the bottom of the crusher body 1 by bolts, a second receiving platform 11 is fixedly connected to the outer wall of one side of the weighing discharge box 9 by bolts, an electric push rod 12 is fixedly connected to the outer wall of one side of the second receiving platform 11 by bolts, the electric push rod 12 is fixedly connected to the weighing plate 13 through the output end of one side thereof, a supporting groove 14 is provided on the inner wall of one side of the second receiving platform 11 at a horizontal side position close to the weighing plate 13, a crusher body support frame 15 is fixedly connected to the outer position of the weighing discharge box 9 by bolts, an inner lining plate 16 is provided on the inner wall of one side of the crusher body 1, A breaker hammer 17 is connected to the internal rotation, and an impact plate 18 and a screen 19 are provided on the inner wall of one side of the lining plate 16. The impact plate 18 is located on one side of the screen 19. A PLC controller 20 is fixed to the outer wall of one side of the crusher body support frame 15 by bolts. When the crusher body 1 performs the crushing operation, the electric push rod 12 on the second receiving platform 11 drives the weighing plate 13 to move horizontally through the output end on one side thereof. The weighing plate 13 is inserted into the supporting groove 14, and the weighing plate 13 weighs the crushed raw materials. By timing, the crushing amount after a period of time can be calculated, and the loading amount of the crusher body 1 is adjusted according to the crushing amount to achieve a balance between loading and unloading, thereby ensuring that the amount of raw materials in the crusher body 1 is at the optimal amount, and then the raw materials are crushed more efficiently.

[0037] The present invention further has the following features: the weighing discharge box 9 is connected to the pulverizer body 1 , so that the raw materials crushed in the pulverizer body 1 can be discharged through the weighing discharge box 9 .

[0038] The present invention further: the second receiving platform 11 is a hollow rectangular structure with an open side, the weighing discharge box 9 is connected to the second receiving platform 11, which can provide space for storing the weighing plate 13 and also allow the weighing plate 13 to be inserted into the weighing discharge box 9.

[0039] Working principle: When adjusting the feeding amount, the raw materials to be crushed are poured into the material storage hopper 4, and the material storage hopper 4 stores the raw materials. At this time, the stepper reduction motor 5 does not work, and the electric push rod 12 on the first storage platform 10 is powered on. The electric push rod 12 drives the weighing plate 13 to move horizontally through the output end on one side. The weighing plate 13 is inserted into the supporting groove 14, and the stepper reduction motor 5 works. The stepper reduction motor 5 drives the feeding barrel 7 to rotate through the output end on one side, and the timing timer 6 counts. During the rotation of the feeding barrel 7, the raw materials in the material storage hopper 4 are fed into the material storage hopper 4. The raw materials enter the feeding trough 8. As the feeding cylinder 7 rotates, the feeding trough 8 containing the raw materials rotates to the inside of the first weighing feeding box 2 and the second weighing feeding box 3. The raw materials fall to the weighing plate 13 under the action of gravity. The weighing plate 13 is weighed to detect the feeding amount of the feeding cylinder 7 within a period of time, and calculate the feeding amount of the feeding cylinder 7 per rotation of the feeding cylinder 7 according to the number of rotations of the feeding cylinder 7 within one end of the time. Then, the rotation speed of the feeding cylinder 7 is adjusted according to the feeding speed to meet the required feeding amount. After the quantitative feeding is completed, the electric push rod 12 on the first receiving platform 10 drives the weighing plate 1 3 is reset, and the raw materials on the weighing plate 13 fall into the crusher body 1. The crusher body 1 is crushed by the impact of the rotating crushing hammer 17 on the raw materials and the collision of the raw materials with the impact plate 18. Since the first weighing feeding box 2 and the second weighing feeding box 3 are set, the feeding interval of the first weighing feeding box 2 and the second weighing feeding box 3 is set by the timing timer 6, so as to ensure that when the first weighing feeding box 2 is feeding, the second weighing feeding box 3 is performing quantitative weighing. This cycle ensures that there is always raw material entering the crusher body 1, thereby ensuring that the crusher body 1 can crush the raw materials. Sufficient to avoid idling of the crushing hammer 17 in the crusher body 1. When the crusher body 1 performs the crushing operation, the electric push rod 12 on the second receiving platform 11 drives the weighing plate 13 to move horizontally through the output end on one side thereof. The weighing plate 13 is inserted into the supporting groove 14. The weighing plate 13 weighs the crushed raw materials. By timing, the crushing amount after a period of time can be calculated. The feeding amount of the crusher body 1 is adjusted according to the crushing amount to achieve a balance between feeding and unloading, thereby ensuring that the amount of raw materials in the crusher body 1 is in the optimal amount, and then the raw materials are crushed more efficiently.

[0040] To sum up: the crushing equipment with a material quantity adjustment mechanism sets the feeding interval of the first weighing feeding box 2 and the second weighing feeding box 3 through the timing timer 6, thereby ensuring that when the first weighing feeding box 2 is feeding, the second weighing feeding box 3 is performing quantitative weighing, and so on. The cycle ensures that there is always raw material entering the crusher body 1, thereby ensuring that the crusher body 1 fully crushes the raw material, avoiding the idling of the crushing hammer 17 in the crusher body 1, and measuring the amount of loading and unloading through the weighing plate 13, and then the loading amount of the crusher body 1 can be adjusted according to the crushing amount to achieve a balance between loading and unloading, thereby ensuring that the amount of raw material in the crusher body 1 is at the optimal amount, and then the raw material is crushed more efficiently.
