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.

[0040] The impact block 604 is fixedly connected to the first driving rod 603;

[0041] The first sliding plug 601 pushes the first driving rod 603 to slide, and the first driving rod 603 pushes the impact block 604 to impact the side wall of the silo 2, knocking down the mixed raw materials on the inner wall of the silo 2.

[0042] It should be noted that the discharge pipe 202 is a pipe fitting with a valve that can be purchased on the market.

[0043] It should also be noted that a driving motor 4 is fixedly connected to the base 1 , and a driving end of the driving motor 4 is fixedly connected to the driving shaft 3 .

[0044] It should be further explained that, referring to Figure 5 The impact block 604 is a rubber block available on the market, so that the impact block 604 is not likely to damage the side wall of the silo 2 when it hits the silo 2.

[0045] Reference Figure 3 、 Figure 5 An exhaust pipe 606 is fixedly connected to the first driving cylinder 6, and a one-way pressure relief valve is provided on the exhaust pipe 606.

[0046] A pressure storage chamber 7 is provided in the base 1 , and a first air pipe 605 is fixedly connected to the base 1 . One end of the first air pipe 605 is connected to the pressure storage chamber 7 , and the other end of the first air pipe 605 is connected to the first driving cylinder 6 .

[0047] Reference Figure 5 A control valve is provided on the first gas pipeline 605, and the control valve is a solenoid valve available on the market.

[0048] A second driving cylinder 8 is fixedly connected to the base 1 , a second sliding plug 803 is slidably connected to the second driving cylinder 8 , a second air pipe 806 is fixedly connected to the bottom of the second driving cylinder 8 , and the second air pipe 806 is communicated with the pressure accumulation chamber 7 .

[0049] Reference Figure 4 A one-way valve is provided on the second gas pipeline 806.

[0050] Reference Figure 3 、 Figure 4 An air intake pipe 805 is fixedly connected to the side wall of the second driving cylinder 8, and a one-way air intake valve is provided on the air intake pipe 805.

[0051] It should be noted that the one-way pressure relief valve on the exhaust pipe 606 is a solenoid valve available on the market.

[0052] The second sliding plug 803 is fixedly connected to the second driving rod 801 , and the driving shaft 3 is fixedly connected to the convex plate 301 . The convex plate 301 and the second driving rod 801 abut against each other.

[0053] One end of the second driving rod 801 away from the second sliding plug 803 is fixedly connected to the connecting plate 802 , and a driving wheel 8021 is rotatably connected to the connecting plate 802 . The driving wheel 8021 abuts against the convex plate 301 .

[0054] A first spring 602 is fixedly connected to the first sliding plug 601 , and one end of the first spring 602 away from the first sliding plug 601 is fixedly connected to the inner wall of the first driving cylinder 6 .

[0055] Reference Figure 5 By providing the first spring 602 , the first sliding plug 601 can be quickly reset.

[0056] A second spring 804 is fixedly connected to the second sliding plug 803 , and one end of the second spring 804 away from the second sliding plug 803 is fixedly connected to the inner top wall of the second driving cylinder 8 .

[0057] Reference Figure 4 By providing the second spring 804, the second sliding plug 803 can be quickly reset.

[0058] Reference Figure 1-Figure 5 During use, the material to be mixed is poured into the silo 2 through the feed pipe 201. At this time, the drive motor 4 is turned on, and the drive motor 4 will drive the drive shaft 3 to rotate, and then drive the silo 2 to rotate. During the rotation process of the silo 2, the material in the silo 2 will be turned back and forth, thereby completing the mixing of the materials in the silo 2.

[0059] Reference Figure 3 When the silo 2 rotates, the raw materials in the silo 2 will flip back and forth. The flipped materials will also hit the built-in mixing rod 501 during the sliding and falling process. The large particles of raw materials hitting the mixing rod 501 will be broken up, which can further improve the mixing effect.

[0060] Reference Figure 3-Figure 5 During the mixing process, the driving shaft 3 will also drive the convex plate 301 to rotate. When the convex plate 301 rotates, the convex plate 301 will squeeze the driving wheel 8021, thereby pushing the second driving rod 801 downward. The second driving rod 801 will push the second sliding plug 803 to squeeze the gas in the second driving cylinder 8. The gas in the second driving cylinder 8 will be input into the pressure accumulation chamber 7 through the second gas pipe 806 for storage for subsequent use.

[0061] Reference Figure 4 、 Figure 5As the mixing work is completed, the control valve on the first air pipe 605 can be opened. At this time, the gas in the pressure accumulation chamber 7 will instantly be sprayed into the first driving cylinder 6 through the first air pipe 605, thereby pushing the first sliding plug 601 to slide. The sliding of the first sliding plug 601 will push the first driving rod 603 to move, and then push the impact block 604 to hit the side wall of the silo 2, thereby knocking off the small particles of material adhering to the inner wall due to static electricity, thereby ensuring that the material can be fully discharged later.

[0062] It should be noted that during the discharging process, air can be continuously inflated back and forth in the first driving cylinder 6, so that the impact block 604 can impact the silo 2 back and forth. On the one hand, it can knock down small particles of material adhering to the inner wall due to static electricity. On the other hand, the impact on the silo 2 can make the mixed raw materials gather to the center, thereby quickly completing the discharging and effectively improving the production efficiency.

[0063] It should also be noted that during the exhaust process of the first driving cylinder 6, the one-way pressure relief valve on the exhaust pipe 606 is opened, and the gas in the first driving cylinder 6 can be quickly discharged, thereby preparing for the subsequent impact.

[0064] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
