Description

Technical Field

[0001] The utility model relates to the field of vegetable fertilizer production, in particular to a dry fertilizer crushing and screening device for producing vegetable humic acid compound fertilizer. Background Art

[0002] In the production process of vegetable humic acid compound fertilizer, the dry fertilizer needs to be crushed and screened. The fertilizer can be crushed into fine particles, and unqualified particles can be removed by screening to ensure the quality and uniformity of the compound fertilizer. The crushing part breaks the bulk fertilizer raw materials into small particles, and the screening part classifies these small particles to obtain fertilizer products of different particle sizes according to needs;

[0003] A Chinese patent with publication number CN211329690U discloses an organic fertilizer crushing and screening device, comprising a screening box, a magnetic screen embedded in the left position of the bottom of the screening box, a coarse screening net embedded in the right position of the bottom of the screening box, and a receiving box is arranged below the magnetic screen and the coarse screening net. The screening box is vibrated by a vibration motor, and the magnetic screen screens out refined particles that fall into the receiving box and adsorbs metal impurities therein, thereby improving the quality of the screened organic fertilizer. Thereafter, the coarse screening net screens medium-sized particles, and the two screening nets perform graded screening on the organic fertilizer, and a very small number of particles that are not crushed are collected from the discharge port of the screening box.

[0004] When the organic fertilizer crushing and screening device of the above patent is crushing and screening, the fertilizer slides from the inclined position inside the screening box to complete the screening of particles of different sizes, but the fertilizer can only be screened in a single slide. Particles of different sizes mixed together and sliding will cause part of the fertilizer to be unable to normally contact the filter and complete the screening, and the overall screening ability of the device is weak. Utility Model Content

[0005] The purpose of the utility model is to provide a dry fertilizer crushing and screening device for the production of vegetable humic acid compound fertilizer. The stirring rod can be moved along the ramp through the transmission disc and the first transmission belt, and the movement along the ramp further promotes the fertilizer to be screened, thereby improving the screening efficiency and screening effect, and solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dry fertilizer crushing and screening device for the production of vegetable humic acid compound fertilizer, comprising an outer shell, a pair of crushing wheels are laterally arranged at the upper end of the inner part of the outer shell, a feeding ring is arranged at the upper end of the outer part of the outer shell, a ramp is arranged at the lower end of the inner part of the outer shell, transmission disks are respectively arranged on both sides of the upper end of the ramp, one end of the two transmission disks are connected by a first transmission belt, the front end of the first transmission belt is laterally evenly distributed with connecting blocks, and the front end of the outer part of the connecting block is provided with a stirring rod.

[0007] Preferably, a transmission inner wall is provided inside the stirring rod at one end facing the connecting block, a one-way transmission threaded rod is welded to one end of the connecting block facing the transmission inner wall, and the outer wall of the one-way transmission threaded rod is threadably matched with the inner wall of the transmission inner wall.

[0008] Preferably, the other ends of the two transmission discs are connected via a second transmission belt.

[0009] Preferably, a reserved opening is provided at the front end of the shell.

[0010] Preferably, a first filter screen is disposed on one side of the ramp, and a second filter screen is disposed on one side of the first filter screen.

[0011] Preferably, the mesh size of the second filter is smaller than that of the first filter.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] After the fertilizer is squeezed and crushed by two crushing wheels, it is transmitted by the transmission screw rod and the slope is tilted to make the fertilizer slide inside the shell, and the sliding contact with the first filter screen and the second filter screen in sequence. When contacting the filter screen and screening the particle size, the clockwise rotation of the transmission disc drives the stirring rod to move through the first transmission belt, and the stirring rod moves along the ramp from a low position to a high position. The moving stirring rod will contact the sliding fertilizer, and the fertilizer is forced to roll and repeatedly contact the first filter screen and the second filter screen through the contact.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to solve the problem that in the prior art, when the organic fertilizer crushing and screening device is crushing and screening, the fertilizer slides from the inclined position inside the screening box to complete the screening of particles of different sizes, but the fertilizer can only complete the screening when it slides down once, and particles of different sizes are mixed together and slide, which will cause a part of the fertilizer to be unable to normally contact the filter screen and complete the screening, and the overall screening ability of the device is weak, this embodiment provides the following technical solutions:

[0023] The dry fertilizer crushing and screening device for producing vegetable humic acid compound fertilizer comprises a shell 1, and a ramp 4 is arranged at the lower end of the shell 1. The crushed fertilizer falls to the upper end of the ramp 4 after being transmitted. The inclined ramp 4 forces the fertilizer to slide to a lower place. Figure 1 and Figure 4 As shown, a first filter screen 15 is provided on one side of the ramp 4, and a second filter screen 16 is provided on one side of the first filter screen 15. The sliding fertilizer will contact the first filter screen 15 and the second filter screen 16 in sequence. The second filter screen 16 has a smaller mesh than the first filter screen 15. It will preferentially contact the first filter screen 15 to screen out smaller particles, and then pass through the second filter screen 16 to screen out larger particles. The remaining fertilizer that cannot be filtered will be directly discharged from the bottom of the ramp 4, and the user can pour it into the equipment again to complete the crushing and screening.

[0024] In this embodiment, transmission discs 6 are respectively provided on both sides of the upper end of the ramp 4, and one end of the two transmission discs 6 is connected by a first transmission belt 7. Figure 4 and Figure 5As shown, the first transmission belt 7 is tightened by two transmission discs 6, and the first transmission belt 7 can be driven by the rotation of the transmission disc 6. The front end of the first transmission belt 7 is evenly distributed with connecting blocks 8. The first transmission belt 7 drives the connecting blocks 8 to move during the transmission process. The front end of the connecting block 8 is provided with a stirring rod 9. The stirring rod 9 moves laterally along the ramp 4 after the transmission. The stirring rod 9 moves from the lower part of the ramp 4 to the higher part. The movement directly contacts the sliding fertilizer, and the fertilizer rolls through the contact. At the same time, the collision of the fertilizer causes the fertilizer to repeatedly contact the first filter screen 15 and the second filter screen 16, and repeated screening is performed to ensure complete screening and improve the screening effect.

[0025] In this embodiment, a transmission inner wall 19 is provided at one end of the stirring rod 9 facing the connecting block 8. Figure 5 and Figure 6 As shown, a one-way transmission threaded rod 20 is welded to one end of the connecting block 8 facing the transmission inner wall 19, and the outer wall of the one-way transmission threaded rod 20 is threadedly matched with the inner wall of the transmission inner wall 19, so that the stirring rod 9 can be installed to the outside of the connecting block 8 after being rotated through the threaded match. Similarly, the stirring rod 9 can be disassembled and replaced by rotating it.

[0026] In this embodiment, if Figure 2 As shown, the other ends of the two transmission discs 6 are connected by a second transmission belt 11, and one of the transmission discs 6 can drive the two transmission discs 6 to rotate at the same time after the output of the motor is transmitted by the second transmission belt 11. The transmission of the second transmission belt 11 assists the transmission of the first transmission belt 7, which can improve the stability of the transmission.

[0027] In this embodiment, if Figure 1 , Figure 3 and Figure 4 As shown, a pair of crushing wheels 14 are transversely arranged at the upper end of the housing 1. The two crushing wheels 14 rotate relative to each other to squeeze the fertilizer. A transmission block 13 is arranged at one end of the two crushing wheels 14. The two transmission blocks 13 are connected by a bidirectional transmission threaded rod 12. The outer wall of the bidirectional transmission threaded rod 12 is threadedly matched with the inner wall of the transmission block 13. The rotation of the bidirectional transmission threaded rod 12 can drive the crushing wheels 14 to move, and the movement of the crushing wheels 14 can adjust the spacing.

[0028] In this embodiment, if Figure 1 and Figure 2As shown, a pair of motors for output are arranged at the other ends of the two crushing wheels 14, and the output shafts of the motors are independently connected to the corresponding crushing wheels 14. The crushing wheels 14 are rotated in different directions through the output of the crushing wheels 14. The transmission block 13 is rotatably connected to the center position of the crushing wheel 14. The transmission block 13 can be used as a support for the crushing wheel 14 through the transmission connection, so that the crushing wheel 14 is mounted inside the housing 1. A feeding ring 2 is arranged at the upper end of the outer shell 1. The fertilizer gathered through the feeding ring 2 can contact the two crushing wheels 14 and complete the crushing.

[0029] In this embodiment, if Figure 4 As shown, a power supply battery 18 is provided on one side of the housing 1, and a support frame 17 is provided on the upper end of the power supply battery 18. The housing of the motor connected to the crushing wheel 14 is slidably inserted into the support frame 17. When the two-way transmission threaded rod 12 rotates and adjusts the distance between the two crushing wheels 14, the connected motor is directly driven to move. The power supply battery 18 supplies power to the motor outside the housing 1, and the operation of the device is realized through the output of the motor.

[0030] In this embodiment, if Figure 1 , Figure 2 and Figure 4 As shown, a pair of transmission screw rods 3 for transmission are arranged between the lower end of the crushing wheel 14 and the upper end of the ramp 4. The transmission screw rods 3 transmit the crushed fertilizer after being output by the motor and rotating, so that the fertilizer is transmitted to the upper end of the ramp 4;

[0031] In this embodiment, if Figure 1 and Figure 2 As shown, a collecting frame 5 is respectively disposed at the lower end of the first filter screen 15 and the lower end of the second filter screen 16 , and the two collecting frames 5 can be slidably placed in a reserved position at the lower end of the housing 1 .

[0032] In this embodiment, if Figure 1 and Figure 2 As shown, a reserved opening 10 is provided at the front end of the housing 1 , and the reserved opening 10 can facilitate the installation and removal of the stirring rod 9 .

[0033] Working principle: When the device is used to crush and screen the fertilizer, the motor corresponding to the two-way transmission threaded rod 12 is started according to the different requirements of the crushing size. The rotation of the two-way transmission threaded rod 12 can simultaneously produce relative movement with the two external transmission blocks 13. After being restricted by the outer shell 1, the transmission block 13 is converted from rotational movement to horizontal linear movement, so that the two crushing wheels 14 move relative to each other, and the relative movement completes the adjustment of the spacing. The dry fertilizer is put into the device from the position of the feed ring 2, and contacts the rotating crushing wheel 14 to complete the extrusion and crushing. After extrusion and crushing, the fertilizer falls to the periphery of the transmission screw rod 3. The rotation of the transmission screw rod 3 can continuously push the fertilizer, so that the fertilizer continues to move and moves to the ramp 4. At the highest position, the inclination of the slope will force the fertilizer to slide downward, slide and contact the first filter 15 and the second filter 16 in turn. After screening one by one, the remaining fertilizer is discharged from the bottom end of the ramp 4. In the process of the fertilizer contacting the first filter 15 and the second filter 16, the motor corresponding to the transmission disk 6 is started, and the output of the transmission disk 6 can drive another transmission disk 6 to rotate through the second transmission belt 11. The rotation of the two transmission disks 6 can drive the first transmission belt 7 for transmission. During the transmission process of the first transmission belt 7, the stirring rod 9 will be driven to move, so that the stirring rod 9 slides along the ramp 4. During the sliding process, it will contact the sliding fertilizer, and the collision will cause the fertilizer to flip and then repeatedly contact the first filter 15 and the second filter 16.
