[0033] The embodiment of the present invention can realize the rotation of the driving sprocket when the stirring shaft rotates through the above-mentioned arrangement, thereby driving the driven sprocket to rotate through the chain belt, and then rotating the two threaded rods, allowing the screw sleeves on them to move along the threaded rods, and moving the scraper connected to the screw sleeves, which can scrape off the raw materials adhering to the inner wall of the crushing box, thereby preventing the residue of the raw materials. More specifically, the driving sprocket is coaxially arranged with the stirring shaft and connected to the driven sprocket through the chain belt. When the stirring shaft rotates, the driving sprocket also rotates therewith, thereby driving the driven sprocket to rotate through the chain belt, and then driving the two threaded rods to rotate synchronously, so that the screw sleeves on them move up and down along the threaded rods, driving the scraper to scrape off the raw materials adhering to the inner wall of the crushing box, and preventing the raw materials from accumulating and remaining on the inner wall of the crushing box. The inner wall of the crushing box can be automatically cleaned, avoiding the residue and waste of raw materials, while keeping the inner wall of the crushing box smooth and clean, improving the crushing effect and equipment life.

[0034] In this embodiment, a material return mechanism is arranged between the crushing box 1 and the screening box 2, and the material return mechanism includes an air pump 40, a lower ventilation pipe 41, an upper ventilation pipe 42 and a three-way valve 43; the air pump 40 is installed between the crushing box 1 and the screening box 2; the lower ventilation pipe 41 is connected to the air inlet end of the air pump 40 and passes through the interior of the crushing box 1; the upper ventilation pipe 42 is connected to the air outlet end of the air pump 40; the three-way valve 43 is arranged at the top end of the upper ventilation pipe 42 and is respectively connected to the crushing box 1 and the screening box 2.

[0035] The embodiment of the present invention can start the air pump through the above-mentioned setting. The air pump can be operated to extract the raw material at the bottom of the crushing box through the lower ventilation pipe, and return it to the upper part of the crushing box through the upper ventilation pipe and the three-way valve opened in the direction of the crushing box.

More specifically, during the crushing of the raw material, the air pump is started to form a negative pressure between the lower ventilation pipe and the upper ventilation pipe, and the raw material in the crushing box is sucked into the lower ventilation pipe, and then the direction is changed by the three-way valve, and the raw material is sent from the upper ventilation pipe to the top of the crushing box again, so that the raw material contacts the crushing knife again, and the secondary crushing is performed to improve the uniformity of the crushing of the raw material. This process can be repeated many times until the required particle size requirement is reached. After the raw material is completely crushed, adjust the three-way valve, close the pipeline in the direction of the crushing box, open the pipeline in the direction of the screening box, and transport the raw material from the air pump to the screening box for multi-stage screening. This technical solution can realize the recycling of raw materials, reduce the loss and cost of raw materials, and at the same time improve the number of crushing times and particle size uniformity of raw materials. This technical solution can also realize the rapid transportation of raw materials, shorten production time and improve production efficiency.

[0036] In this embodiment, a discharging mechanism is arranged in the middle of the screening box 2, and the discharging mechanism includes a second motor 50, a screw rod 51, a partition plate 52 and a bearing plate 53. The second motor 50 is installed at the lower part of the screening box 2; the screw rod 802 is arranged through one side of the inside of the screening box 2 and is connected to the power output end of the second motor 50; the partition plate 52 is evenly arranged inside the screening box 2; the bearing plate 53 is sleeved around the screw rod 51 and the partition plate 52. The bearing plate 53 is threadedly connected to the screw rod 51, and the bearing plate 53 is slidably connected to the partition plate 52.

[0037] The embodiment of the present invention can realize that when it is necessary to take out the raw materials after crushing and screening, the second motor can drive the screw to rotate, so that the carrying plate moves downward along the partition plate, and then the material taking door can be opened to take out the raw materials in the screening box, which makes the taking out more convenient. More specifically, after the raw materials are screened, the second motor is started to drive the screw to drive the carrying plate to move downward along the partition plate, and the raw materials of different particle sizes are scraped off from multiple elastic filter screens and moved to the outlet of the screening box. Afterwards, the material taking door is opened, and the raw materials of different particle sizes are taken out from the discharging mechanism for different subsequent processing. This technical solution can realize the automatic discharging of raw materials, improve the discharging efficiency and accuracy, and avoid the residue and waste of raw materials. This technical solution can also realize the classified removal of raw materials.

[0038] In this embodiment, a screening mechanism is arranged above the inside of the screening box 2, and the screening mechanism includes an adjustment plate 60, a vibration plate 61, an electric push rod 62 and an elastic filter 63; the adjustment plate 60 is arranged above the screening box 2; the vibration plate 902 is evenly arranged on the top of the screening box 2 and connected to the adjustment plate 901; the electric push rod 903 is arranged between the adjustment plate 901 and the screening box 2; and the elastic filter 904 is evenly arranged above the inside of the screening box 2. The vibration plate 61 is arranged in an L shape and is slidably connected to the top of the screening box 2, one end of the vibration plate 61 is in contact with the elastic filter 63, and the apertures of the multiple elastic filters 63 decrease from large to small from left to right.

[0039] The embodiment of the present invention can realize that after the raw material enters the screening box, the conveyed air pressure can push the raw material through multiple elastic filter screens one by one, thereby screening the raw material into multiple areas with different particle sizes, and as the electric push rod drives the adjustment plate to move up and down, the vibration plate can be adjusted up and down to knock the elastic filter screen, so that the elastic filter screen vibrates, and the raw material materials that are clogged and adhered to its surface fall off, improving the filtering effect of the elastic filter screen, and making the entire screening process more durable and safe. More specifically, after the raw material is conveyed from the crushing box to the screening box, due to the action of the conveyed air pressure, the raw material passes through elastic filter screens with different apertures one by one, thereby classifying the raw material into multiple areas with different particle sizes and accumulating on the carrying plate. At the same time, the electric push rod is started, so that the adjustment plate drives the vibration plate to move up and down, periodically knocks the elastic filter screen, and the elastic filter screen vibrates, and the raw material materials that are adhered to its surface or in the hole fall off, improving the filtering efficiency and cleanliness of the elastic filter screen, and preventing the elastic filter screen from being blocked and damaged. This technical solution can achieve multi-level screening of raw materials, improve screening quality and efficiency, and avoid clogging and damage of the screen, so as to obtain raw materials of different particle sizes and meet the needs of different industries. This technical solution can also realize automatic cleaning and protection of the screen, and extend the service life and stability of the screen.

[0040] The embodiment of the present invention can realize adding raw materials into the crushing box by setting a crushing box and a screening box, and the stirring shaft drives the crushing knife to crush the raw materials by running the first motor, and the high-pressure airflow is input to repeatedly collide, rub and shear with the raw materials in the crushing box to crush them to form powdered raw materials, and the cleaning mechanism can also prevent the raw materials from remaining; more specifically, the raw materials are added to the crushing box, the first motor is started, the stirring shaft rotates at a high speed, and the crushing knife is driven to mechanically crush the raw materials, and the air intake pipe is opened at the same time, and the high-pressure airflow is sprayed into the crushing box, so that the raw material particles and the airflow produce strong impact, friction, and shearing effects, further refining the particle size of the raw materials to form powdered raw materials. During the crushing process, the cleaning mechanism is started, so that the threaded rod drives the screw sleeve and the scraper to move up and down along the inner wall of the crushing box 1, and the raw materials adhering to the inner wall are scraped off to prevent the raw materials from accumulating and remaining on the inner wall. This technical solution can realize the efficient crushing of raw materials, increase the surface area and activity of raw materials, and reduce the loss and waste of raw materials, thereby improving product quality and utilization rate. After the raw material in the crushing box is crushed for a period of time, the input of high-pressure airflow is stopped, and then the raw material can be extracted and re-input to the top of the crushing box through the return mechanism 7, and further shredded with the crushing knife, and the crushing effect is improved by circulating with the crushing knife; more specifically, after the raw material in the crushing box is crushed for a certain period of time, the air inlet pipe is closed, the input of high-pressure airflow is stopped, and the air pump is started at the same time, so that the lower ventilation pipe and the upper ventilation pipe form a negative pressure, and the raw material in the crushing box is sucked into the lower ventilation pipe, and then the direction is changed by the three-way valve, and the raw material is re-sent from the upper ventilation pipe to the top of the crushing box, so that the raw material is contacted with the crushing knife again, and secondary crushing is performed to improve the fineness and uniformity of the raw material. This process can be repeated many times until the required particle size requirements are reached. This technical solution can realize the recycling of raw materials, reduce the loss and cost of raw materials, and at the same time improve the number of crushing times and particle size uniformity of raw materials. After the raw material is crushed, it is input into the screening box. The screening mechanism in the screening box can ensure the stability of the multi-stage screening process. After the raw material is classified, it can be taken out through the discharging mechanism to obtain powdered raw material with different particle sizes, so as to perform different subsequent treatments according to the powdered raw material with different particle sizes. More specifically, after the raw material is crushed, the connecting valve between the crushing box and the screening box is opened, the raw material is transported from the crushing box 1 to the screening box, the second motor is started, the screw rod drives the carrier plate to move up and down, and the raw material is evenly spread on multiple elastic filter screens. At the same time, the electric push rod is started, the adjustment plate drives the vibration plate to adjust up and down, and the elastic filter screen is knocked, so that the raw material is graded through the elastic filter screens with different apertures to obtain raw material with different particle sizes.After that, the carrier plate is moved to the outlet of the screening box, and the raw materials of different particle sizes are taken out from the discharging mechanism for different subsequent treatments. This technical solution can realize multi-stage screening of raw materials, improve screening quality and efficiency, avoid clogging and damage of the screen, and obtain raw materials of different particle sizes to meet the needs of the industry.

[0041] It is further explained that the crushing box 1 and the screening box 2 are fixedly arranged on the top of the mounting plate 13, and a plurality of shock-absorbing mechanisms for absorbing the shock of the crushing box 1 and the screening box 2 are arranged below the mounting plate 13, and the shock-absorbing mechanism includes a shock-absorbing support seat 7 and a shock-absorbing power generation mechanism 8; the shock-absorbing support seat 7 is arranged below the mounting plate 13, and the shock-absorbing support seat 7 supports the mounting plate 13; the vibration power generation mechanism 8 is arranged on the shock-absorbing support seat 7 and generates electricity through the vibration of the shock-absorbing support seat 7.

[0042] In the embodiment of the present invention, a shock absorbing mechanism is arranged below the whole formed by the crushing box, the screening box and the mounting plate, and the shock absorbing mechanism is used to buffer the vibration energy generated when the crushing box and the screening box are working. At the same time, a vibration power generation mechanism is arranged on the shock absorbing support seat, so that the shock absorbing support seat can also generate electricity during the vibration process, thereby improving the energy utilization rate and the power generation efficiency.

[0043] In this embodiment, the shock-absorbing support seat 7 includes a base 70, a sliding support rod 71, a fixed block 72, a fixed ring 73 and a buffer elastic member 74; the base 70 is fixed on the ground, and a vertical sliding groove is provided on the base 70; the sliding support rod 71 is slidably fitted on the base 70; the fixed block 72 is arranged on the sliding support rod 71; the fixed ring 73 is fixed on the lower end surface of the mounting plate 13, and the outer side of the fixed ring 73 is connected to the sliding support rod 71; the buffer elastic member 74 is sleeved on the sliding support rod 71, and the buffer elastic member 74 is located between the fixed block 72 and the base 70.

[0044] It should be noted that the buffer elastic member of this embodiment can be a spring, a spring sheet or other elastic structure. When the crushing box and the screening box vibrate during operation or when the crushing box and the screening box vibrate due to external impact force, the buffer elastic member can play a buffering role to reduce the vibration of the crushing box and the screening box.

[0045] In this embodiment, the vibration power generation mechanism 8 includes a permanent magnet 80 and a coil 81; the permanent magnet 80 is fixed on both sides of the base 70, and the magnetic field generated by the permanent magnet 80 covers the position of the buffer elastic member 74 and the fixed block 72; the inner upper part of the coil 81 is fixed on the fixed block 72.

[0046] The above-mentioned arrangement of the embodiment of the present invention can realize that when the crushing box and the screening box generate vibrations during operation or when the crushing box and the screening box vibrate due to external impact force, the crushing box and the screening box transmit the vibrations to the fixed block in the shock-absorbing support seat, and the fixed block vibrates up and down, thereby causing the coil fixed on the fixed block to move up and down, thereby causing the coil to cut the magnetic flux lines generated by the permanent magnets on both sides, thereby generating current in the coil. The coil of this embodiment can be connected to the device or equipment to be powered by a wire. Thereby, the current generated in the coil is used to power the equipment to be powered through the wire. This embodiment generates electricity through vibration, thereby improving energy utilization and power generation efficiency.

[0047] Finally, it should be noted that the above only describes in detail the specific embodiments of the present invention. However, the present invention is not limited to the specific embodiments described above. Equivalent modifications and substitutions made by those skilled in the art to the present invention are also within the scope of the present invention. Therefore, equal changes and modifications made without departing from the spirit and scope of the present invention are all within the scope of the present invention.
