Detailed ways

As shown in FIG. 1 to FIG. 7 , the present invention includes a tank body 1 , a fixing cylinder 2 , a vibrating assembly, a dust collecting assembly and a crushing assembly. The present invention will be described in detail below in conjunction with the accompanying drawings.

As shown in Figures 1 to 7, the raw material crushing device for the rear wall of the solar greenhouse includes a tank body 1, a fixed cylinder 2, a vibration assembly, a dust collection assembly and a crushing assembly. The fixed cylinder 2 and the tank body 1 are arranged up and down and connected. The fixed cylinder 2 is a cylindrical structure, and the tank body 1 is a circular structure or a square structure. The top of the fixed cylinder 2 is open for the input of straw, and the bottom of the fixed cylinder 2 is connected to the upper part of the inner cavity of the tank body 1. The vibration assembly includes a guide block 7, a fixed box 6 and a driving mechanism. The guide block 7 and the fixed box 6 are located in the fixed cylinder 2 and are arranged up and down. The guide block 7 is a conical structure with a small upper end and a large lower end, and the guide block 7 is a hollow structure. The fixed box 6 is fixedly connected to the inner wall of the fixed cylinder 2, specifically: the outer wall of the fixed box 6 and the inner wall of the fixed cylinder 2 are fixedly connected by a plurality of rods evenly arranged along the circumferential direction. After the straw is put into the fixed cylinder 2, the structure of the guide block 7, on the one hand, blocks the straw and slows down the speed of the straw sliding down; on the other hand, it guides the downward trajectory of the straw so that the straw slides along the guide block 7 to the inner wall of the fixed cylinder 2. As shown in FIG6 , a slide bar 9 is slidably mounted on the side wall of the guide block 7, and one end of the slide bar 9 has a vibrating block 10 located between the outer wall of the guide block 7 and the inner wall of the fixed cylinder 2, and the driving mechanism is used to drive the slide bar 9 to reciprocate relative to the guide block 7. Specifically, the slide bar 9 is a plurality of slide bars evenly arranged along the circumferential direction, as shown in FIG7 , a spring 17 is sleeved on the outside of the slide bar 9, and the spring 17 is located inside the guide block 7, one end of the spring 17 is fixedly connected to the inner wall of the guide block 7, and the other end of the spring 17 is fixedly connected to the other end of the slide bar 9, and the distance between the vibrating block 10 and the inner wall of the fixed cylinder 2 is the largest under the action of the spring 17. As shown in FIG2 and FIG7 , the driving mechanism includes a driving disk 8, which is fixed to the upper end of the rotating shaft 4, and the driving disk 8 is a regular polygonal structure, such as a regular triangle structure, and the driving disk 8 squeezes the other end of the slide bar 9 during rotation, thereby driving the slide bar 9 to move relative to the side wall of the guide block 7. When the point at the edge of the driving disc 8 farthest from the center of the driving disc 8 contacts the other end of the slide bar 9, the distance between the vibrating block 10 and the inner wall of the fixed cylinder 2 is the smallest, and then the point at the edge of the driving disc 8 farthest from the center of the driving disc 8 gradually separates from the other end of the slide bar 9. At this time, under the action of the spring 17, the slide bar 9 is reset, thereby realizing the reciprocating movement of the slide bar 9 relative to the side wall of the guide block 7. When the vibrating block 10 moves toward the inner wall of the fixed cylinder 2, the vibrating block 10 cooperates with the fixed cylinder 2 to squeeze the straw, thereby crushing the mud on the straw.

As shown in FIG2 , the crushing assembly includes a motor 3, a rotating shaft 4 and a crushing knife 5. The motor 3 is fixed at the bottom of the tank body 1. The lower end of the rotating shaft 4 is fixedly connected to the output end of the motor 3. The upper end of the rotating shaft 4 extends into the guide block 7. The crushing knife 5 is fixed in the upper middle part of the rotating shaft 4 and is located below the fixed box 6. Specifically, the crushing knife 5 is arranged in multiple groups up and down, and each group includes multiple crushing knives 5 evenly arranged along the circumferential direction. The bottom of the tank body 1 has a dust cover 18, which is a conical structure with a small upper end and a large lower end. The dust cover 18 has a partition 23 inside. The partition 23 divides the inner cavity of the dust cover 18 into an independent negative pressure chamber 24 and a motor cavity 25, and the negative pressure chamber 24 and the motor cavity 25 are arranged up and down. The motor 3 is located in the motor cavity 25, and the rotating shaft 4 passes through the negative pressure chamber 24 and the fan blade 11 located in the negative pressure chamber 24 is fixed on the outer wall of the rotating shaft 4. When the fan blade 11 rotates with the rotating shaft 4, negative pressure is generated in the negative pressure chamber 24.

As shown in Figure 2, the dust collection assembly includes a negative pressure chamber 24. As shown in Figure 3, the side wall of the rotating shaft 4 has side holes 12 arranged up and down, and the side hole 12 located at the top is located in the fixed box 6. As shown in Figure 2, the side hole 12 located at the bottom is connected to the negative pressure chamber 24. As shown in Figure 3, the side wall of the fixed box 6 has first dust collection holes 13 evenly arranged along the circumferential direction. As shown in Figure 3, the rotating shaft 4 has an axial cavity 21 connected to the side holes 12. The first dust collection hole 13 and the side hole 12 connect the inner cavity of the fixed cylinder 2 with the axial cavity 21. The dust in the fixed cylinder 2 enters the fixed box 6 through the first dust collection hole 13, and then enters the axial cavity 21 through the upper side hole 12, and then enters the negative pressure chamber 24 through the lower side hole 12, thereby realizing dust collection.

To enhance the dust collection effect and efficiency, as shown in FIG4 , the side wall of the fixed cylinder 2 is provided with an annular cavity 15, and the inner wall of the fixed cylinder 2 is provided with a second dust collection hole 16 connected to the annular cavity 15. As shown in FIG5 , the bottom of the fixed cylinder 2 is provided with a bottom hole 22 connected to the annular cavity 15. As shown in FIG2 , a dust collection pipe 14 is provided between the bottom of the fixed cylinder 2 and the negative pressure chamber 24, one end of the dust collection pipe 14 is connected to the bottom hole 22, and the other end of the dust collection pipe 14 extends into the negative pressure chamber 24. After negative pressure is generated in the negative pressure chamber 24, the dust in the fixed cylinder 2 enters the annular cavity 15 through the second dust collection hole 16, then enters the dust collection pipe 14 through the bottom hole 22, and finally enters the negative pressure chamber 24. To achieve the transfer of dust, the present invention is further provided with a dust transfer pipe 19, the upper end of which extends into the lower part of the negative pressure chamber 24. After negative pressure is generated in the negative pressure chamber 24, the airflow and dust flow to the bottom of the negative pressure chamber 24, and then move out of the negative pressure chamber 24 through the dust transfer pipe 19. The other end of the dust transfer pipe 19 can also be connected to a vacuum cleaner. After starting the vacuum cleaner, the negative pressure in the negative pressure chamber 24 can be increased, and the dust in the negative pressure chamber 24 can be quickly transferred out, so that the dust generated by vibration is sucked in through the first dust suction hole 13 and the second dust suction hole 16 as much as possible.

In order to transfer the crushed straw, as shown in FIG2 , the bottom of the tank body 1 is provided with a plurality of straw transfer pipes 20, the top of the straw transfer pipe 20 is flush with the bottom surface of the inner cavity of the tank body 1, and the lower end of the straw transfer pipe 20 extends out of the tank body 1. The crushed straw falls into the straw transfer pipe 20 and is moved out of the tank body 1.

The working principle of the present invention is described below:

Put straw into the fixed cylinder 2, and the straw slides down along the outer wall of the guide block 7, start the motor 3, and the rotating shaft 4 rotates to drive the driving disk 8 to rotate. The driving disk 8 squeezes the sliding rod 9 so that the vibrating block 10 is close to the inner wall of the fixed cylinder 2. The vibrating block 10 cooperates with the fixed cylinder 2 to squeeze the straw, on the one hand, squeezing and crushing the mud on the straw, and on the other hand, squeezing the straw to make it soft. The rotation of the rotating shaft 4 drives the rotation of the fan blade 11, so that negative pressure is generated in the negative pressure chamber 24. The dust falling on the straw enters the fixed box 6 through the first dust suction hole 13 under the action of negative pressure, and then enters the shaft cavity 21 through the upper side hole 12, and then enters the negative pressure chamber 24 through the lower side hole 12. At the same time, the dust also enters the annular cavity 15 through the second dust suction hole 16, and then enters the dust suction pipe 14 through the bottom hole 22, and finally enters the negative pressure chamber 24. The dust in the negative pressure chamber 24 enters the dust transfer pipe 19, moves out of the negative pressure chamber 24 for collection and treatment, thereby avoiding dust leakage. The straw cleaned of mud blocks enters the crushing area where the crushing knife 5 is located. After being crushed, the dust mixed in the straw fragments is greatly reduced, so that the straw is more compact in the subsequent extrusion molding process.

The present invention firstly vibrates the straw by setting a vibrating component to crush the soil attached to the surface of the straw, and at the same time softens the straw by vibration to facilitate subsequent crushing; and by setting a dust suction component, dust generated by the vibration is adsorbed to prevent a large amount of dust from falling with the straw into the crushing process, so that the dust mixed in the straw after crushing is greatly reduced.
