Detailed Embodiment

[0019] The technical solutions in the present utility model will be further described below in conjunction with the drawings and embodiments.

[0020] As Figures 1-3 shown, an embodiment of the present utility model provides a urea crusher for water-soluble fertilizer production, including:

[0021] Base 1 and crushing main body 2. A set of feet 18 are installed on the lower end face of the base 1. Through the stabilizing effect of the feet 18, the staff can stably place the device at the designated position, facilitating the staff to carry out subsequent work. A support block 3 is installed on the upper end face of the base 1. A placement groove 4 is opened on the support block 3. A storage box 5 is slidably connected in the placement groove 4. Through the storage function of the storage box 5, the processed products can be collected in the storage box 5 and it is convenient for the staff to take out. An outlet pipe 6 is installed on the lower end face of the crushing main body 2. The processed products are output from the outlet pipe 6 and collected through the storage box 5, facilitating the staff to carry out subsequent work and meeting the usage requirements of the staff. A dust-proof component is installed at the feeding end of the crushing main body 2. The dust-proof component includes a box body 13 installed at the feeding end of the crushing main body 2. An inlet opening 14 is opened on the box body 13;

[0022] The inlet opening 14 faces the feeding end of the crushing main body 2. Urea enters from the inlet opening 14 and enters the crushing main body 2 from the feeding end of the crushing main body 2 for processing. A sliding groove 15 is opened on the inlet opening 14. A protective plate 16 is slidably connected in the sliding groove 15. The protective plate 16 is installed in a convex shape, and the sliding groove 15 is also installed in a convex shape. The protective plate 16 matches the sliding groove 15. At this time, when the protective plate 16 slides in the sliding groove 15, no shaking will occur. At the same time, the convex-shaped protective plate 16 can be more convenient for the threaded rod 17 to drive forward. One end of the protective plate 16 is threadedly connected to the threaded rod 17. The other end of the threaded rod 17 rotates through the box body 13. A knob 20 is installed at the end of the threaded rod 17 away from the box body 13. By rotating the knob 20, the staff can easily rotate the threaded rod 17, so that the threaded rod 17 can easily drive the protective plate 16 to slide in the sliding groove 15. Through the installation of the above dust-proof component, when processing is not required, the protective plate 16 closes the inlet opening 14 to prevent environmental dust from entering the crushing main body 2, meeting the usage requirements of the staff. When processing is required;

[0023] The protective plate 16 is driven to move by rotating the threaded rod 17 to open the feed inlet 14, facilitating the processing by the staff. There are two symmetrically arranged dust suction components. The dust suction component includes a ventilation opening 7 formed in the support block 3. A cross rod 8 is installed in the ventilation opening 7, and a fan 9 is installed on the cross rod 8. The fan 9 is a prior art. By turning on the fan 9, a suction force can be formed to absorb the dust splashed up after the product produced from the discharge pipe 6 lands. Two symmetrically arranged slide rails 10 are fixedly connected to the ventilation opening 7. One end of the two slide rails 10 is fixedly connected to a limiting rod 11 together. A dust suction net 12 is slidably connected in the two slide rails 10 together. Due to the blocking effect of the dust suction net 12, the dust will be attached to the dust suction net 12. Handles 19 are installed at one end of the two dust suction nets 12 respectively. Through the handles 19, the staff can easily replace and clean the dust suction net 12, facilitating the subsequent processing work. The dust suction net 12 covers the ventilation opening 7. Through the above structure, the fan 9 absorbs the dust, then the dust is attached to the dust suction net 12, and the dust suction net 12 that can be quickly installed and disassembled meets the use requirements of the staff.

[0024] The detailed working process of the present utility model is as follows:

[0025] First, the staff stably places the device at the designated position through the footrest 18. Then, the staff rotates the knob 20, which drives the threaded rod 17 to rotate, thereby driving the protective plate 16 threadedly connected thereto to slide in the sliding groove 15, thus opening the feed inlet 14. Then, the staff can take out the urea and pour it into the feed inlet 14, and it enters the feed end in the crushing main body 2 from the feed inlet 14. The staff turns on the crushing main body 2 to process and crush the urea in the crushing main body 2. Then, the processed product is produced from the discharge pipe 6 on the crushing main body 2 and falls into the storage box 5 to complete the collection. During the collection process, the falling product generates dust due to the impact. At this time, the staff can turn on the fan 9. The fan 9 rotates to generate suction, absorbs the air in the environment to generate wind force, and drives the scattered dust to be absorbed and attached to the installed dust suction net 12. Until the processing and storage are completed, the staff rotates the knob 20 to seal the feed inlet 14 with the protective plate 16 again, and then turns off the fan 9. At this time, a large amount of dust is attached to the dust suction net 12. The staff pulls the handle 19 to easily pull out the dust suction net 12 and clean and replace it. Align the new dust suction net 12 with the two slide rails 10, push the dust suction net 12 in, and complete the installation under the limiting action of the limiting rod 11, facilitating the subsequent work of the staff and meeting the use requirements of the staff.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
