[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 3 As shown, an embodiment of the present utility model provides an organic fertilizer raw material screening device for screening raw materials for producing organic fertilizers, so as to screen the organic fertilizer raw materials according to particle size.

[0023] Please refer to Figure 1 and Figure 2 The organic fertilizer raw material screening device includes a frame 1, a guide seat 2 is provided on the frame 1, and a movable slider 3 is provided on the guide seat 2, the frame 1 is also provided with a first driving component 4 connected to the slider 3, and the first driving component 4 drives the slider 3 to reciprocate on the guide seat 2, the guide seat 2 is provided with a rotatable screen frame 5 and a second driving component 6 connected to the screen frame 5, the screen frame 5 is provided with a screen 51 and a vibration motor 52, the screen frame 5 is driven to shake by the first driving component 4, and the screen frame 5 and the screen 51 are driven to shake by the vibration motor 52, so that the organic fertilizer raw material poured on the screen 51 can be screened; one end of the screen frame 5 is provided with a discharge port 53 connected to the space surrounded by the screen frame 5 and the screen 51, and the screen frame 5 is also provided with a detachable baffle 54, and the baffle 54 covers the opening of the discharge port 53 At the opening, the frame 1 is also provided with a first material receiving hopper 7 and a second material receiving hopper 8. The first material receiving hopper 7 is located directly below the screen frame 5. The first material receiving hopper 7 is used to receive the organic fertilizer raw material passing through the screen 51. The second material receiving hopper 8 is spaced apart from the screen frame 5 and the second material receiving hopper 8 is movably arranged on the frame 1. The second driving component 6 drives the screen frame 5 with one end having the discharge port 53 to approach or move away from the second material receiving hopper 8. After moving the second material receiving hopper 8 to make the second material receiving hopper 8 close to the screen frame 5, the baffle 54 is removed from the screen frame 5 to open the discharge port 53 and the screen frame 5 is driven to rotate by the second driving component 6 to make the discharge port 53 close to the second material receiving hopper 8. At this time, the vibration motor 52 drives the screen 51 to shake, so that the organic fertilizer raw material in the screen frame 5 can be shaken off and the organic fertilizer raw material falls into the second material receiving hopper 8, so that the screen frame 5 can be cleaned.

[0024] Specifically, the operating steps of screening the organic fertilizer raw material using the organic fertilizer raw material screening device provided in the present embodiment are as follows: pouring the organic fertilizer raw material to be screened into the screen frame 5 and falling on the screen 51, starting the first driving assembly 4 to drive the slider 3 to move back and forth on the guide seat 2 and drive the screen frame 5 to move back and forth, and at the same time, the vibration motor 52 drives the screen frame 5 and the screen 51 to shake and accelerate the organic fertilizer raw material to pass through the screen 51, and the organic fertilizer raw material with a particle size smaller than the diameter of the mesh of the screen 51 after screening passes through the screen 51 and falls into the first receiving hopper 7, and the organic fertilizer raw material with a particle size larger than the diameter of the mesh of the screen 51 is retained on the screen 51, thereby completing the screening operation of the organic fertilizer raw material. When it is necessary to clean the sieve frame 5, first move the second receiving hopper 8 so that the second receiving hopper 8 is close to the sieve frame 5, then start the second driving assembly 6 to drive the sieve frame 5 to rotate so that the end of the sieve frame 5 with the discharge opening 53 is close to the second receiving hopper 8, and remove the baffle 54 to open the discharge opening 53. At this time, the vibrating motor 52 drives the screen 51 to shake and the organic fertilizer raw material on the screen 51 can be shaken into the second receiving hopper 8, so that the sieve frame 5 can be cleaned. After cleaning, the second driving assembly 6 drives the sieve frame 5 to reset, and the baffle 54 and the second receiving hopper 8 can be reset to continue the screening operation of the organic fertilizer raw material. The organic fertilizer raw material screening device provided in the present embodiment simplifies the cleaning step of the sieve frame 5, effectively improves cleaning efficiency, and is simple to operate and easy to use.

[0025] like Figure 1 and Figure 2 As shown, the guide seat 2 is provided with a chute 21, and the length direction of the chute 21 is consistent with the moving direction of the slider 3. The slider 3 is movably arranged in the chute 21 and fits against the inner wall of the chute 21. The chute 21 provided on the guide seat 2 is used to guide the slider 3 to move on the guide seat 2, preventing the slider 3 from unexpectedly deviating when moving, which is beneficial to improving the stability of the screen frame 5 when it moves driven by the slider 3.

[0026] Please combine Figure 1 and Figure 2 A guide rod 22 is provided in the slide groove 21. The axial direction of the guide rod 22 is consistent with the moving direction of the slider 3. The slider 3 is provided with a guide hole that cooperates with the guide rod 22. The cooperation between the guide rod 22 and the guide hole keeps the slider 3 on the guide seat 2, ensuring a reliable cooperation between the slider 3 and the guide seat 2 and preventing the slider 3 from detaching from the guide seat 2 during movement.

[0027] In detail, the guide rod 22 is provided with a first spring 23 and a second spring 24. The first spring 23 and the second spring 24 are respectively located on opposite sides of the slider 3 and respectively abut against the opposite surfaces of the slider 3 in a one-to-one correspondence. The first spring 23 and the second spring 24 provided on the guide rod 22 expand and contract as the slider 3 moves on the guide seat 2. The elastic force provided by the first spring 23 and the second spring 24 pushes the slider 3 to reciprocate on the guide seat 2, ensuring that the slider 3 moves smoothly on the guide seat 2, so that the screen frame 5 moves smoothly under the drive of the slider 3.

[0028] like Figure 2 As shown, in this embodiment, the first driving assembly 4 includes a motor 41 and a crank 42 provided at the output end of the motor 41. The end of the crank 42 away from the motor 41 is rotatably connected to a rocker 43, and the end of the rocker 43 away from the crank 42 is rotatably connected to the slider 3. The motor 41 drives the crank 42 to rotate and drives the rocker 43 to push or pull the slider 3, so that the slider 3 can reciprocate on the guide seat 2. When the crank 42 is continuously rotated under the drive of the motor 41, the slider 3 can be continuously moved on the guide seat 2, thereby driving the screen frame 5 to continuously reciprocate, ensuring that the screen frame 5 effectively screens the organic fertilizer raw material poured into the screen frame 5.

[0029] Please refer to Figure 2 The slider 3 is provided with a mounting seat 31, and the mounting seat 31 is provided with a mounting shaft. The screen frame 5 is provided with a mounting hole that cooperates with the mounting shaft. The screen frame 5 and the slider 3 are rotatably connected through the cooperation between the mounting shaft and the mounting hole, ensuring reliable cooperation between the screen frame 5 and the slider 3 while allowing the screen frame 5 to rotate smoothly relative to the slider 3. Then, the screen frame 5 is driven by the second driving assembly 6 to rotate to an inclined state so that the retained organic fertilizer raw material in the screen frame 5 can be poured out from the discharge port 53.

[0030] Specifically, the second driving assembly 6 includes a cylinder 61 and a telescopic rod 62 arranged at the output end of the cylinder 61, the end of the cylinder 61 away from the telescopic rod 62 is rotatably connected to the slider 3, and the end of the telescopic rod 62 away from the cylinder 61 is rotatably connected to the screen frame 5. When the telescopic rod 62 extends out of the cylinder 61 under the drive of the cylinder 61, the screen frame 5 rotates relative to the slider 3 under the push of the telescopic rod 62 and brings the end of the screen frame 5 having the discharge port 53 close to the second receiving hopper 8. At this time, the organic fertilizer raw material in the screen frame 5 is poured out of the screen frame 5 to clean the screen frame 5. When the telescopic rod 62 retracts into the cylinder 61 under the drive of the cylinder 61, the screen frame 5 rotates and resets relative to the slider 3 under the pull of the telescopic rod 62, so that the screen frame 5 returns to a horizontal position.

[0031] like Figure 2 and Figure 3 As shown, the screen frame 5 is provided with a dovetail groove 55, and the baffle 54 is provided with a block 56 that cooperates with the dovetail groove 55. By inserting the block 56 into the dovetail groove 55, the baffle 54 can be fixed to the screen frame 5 and the discharge port 53 can be closed, ensuring that the organic fertilizer raw material screening device is kept away from the space enclosed by the screen frame 5 and the screen 51 during the screening of the organic fertilizer raw material, preventing the organic fertilizer raw material from falling. When the discharge port 53 needs to be opened, the block 56 can be pulled out of the dovetail groove 55 to remove the baffle 54 from the screen frame 5, which is easy to operate.

[0032] In detail, the frame 1 is further provided with a guide rail 11, and the length direction of the guide rail 11 is consistent with the moving direction of the second receiving hopper 8. The second receiving hopper 8 is provided with a movable block 81 that cooperates with the guide rail 11. The guide rail 11 provided on the frame 1 is used to guide the movement of the second receiving hopper 8, preventing the second receiving hopper 8 from deviating from the preset direction when moving, causing the discharge port 53 and the second receiving hopper 8 to be misaligned, ensuring that the second receiving hopper 8 can move to a position that docks with the discharge port 53, so that all the organic fertilizer raw materials poured out of the screen frame 5 during the cleaning process fall into the second receiving hopper 8.

[0033] like Figure 1As shown, the second receiving hopper 8 is located between the screen frame 5 and the first receiving hopper 7, and the direction of the opening of the first receiving hopper 7 is opposite to the direction of the opening of the second receiving hopper 8. The second receiving hopper 8 is set between the screen frame 5 and the first receiving hopper 7, and the second receiving hopper 8 is moved away from the screen frame 5 to prevent the organic fertilizer raw materials passing through the screen 51 during the screening process from falling into the second receiving hopper 8, and the second receiving hopper 8 is moved to a position close to the screen frame 5 when cleaning the screen frame 5. The opening directions of the first receiving hopper 7 and the second receiving hopper 8 are different, so that the organic fertilizer raw materials poured into the second receiving hopper 8 and the organic fertilizer raw materials falling into the first receiving hopper 7 move in opposite directions respectively, effectively preventing the organic fertilizer after screening from being separated and mixed again.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
