DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figures 1-4 , a water-soluble fertilizer vibration screening device with a crushing function, comprising:

[0024] The machine body 1 has an upper hopper 13 on the top and a material receiving box 14 on the bottom.

[0025] The vibration mechanism includes a vibration motor 2 and a first screening plate 3. The vibration motor 2 is installed on the machine body 1. The output end of the vibration motor 2 is fixedly connected to the first screening plate 3. The first screening plate 3 is slidably connected to the machine body 1. A protective spring 4 is fixedly connected between the end of the first screening plate 3 away from the vibration motor 2 and the machine body 1. The protective spring 4 forms a protective effect on the vibration of the first screening plate 3 to prevent the first screening plate 3 from colliding with the machine body 1 and being damaged.

[0026] The linkage assembly includes a telescopic frame 5, a sliding groove 6, a linkage structure and a second screening plate 12. The bottom end of the telescopic frame 5 is fixedly connected to the first screening plate 3, and the top end is fixedly connected to the second screening plate 12. A plurality of sliding grooves 6 are opened in the body 1, and the plurality of sliding grooves 6 are connected with linkage structures. The ends of the plurality of linkage structures away from the sliding grooves 6 are connected to the second screening plate 12.

[0027] The telescopic frame 5 includes a top frame, a bottom frame and a telescopic spring. The top frame is slidably connected to the top of the bottom frame, the bottom end of the bottom frame is fixedly connected to the first screening plate 3, the top end of the top frame is fixedly connected to the second screening plate 12, and a telescopic spring is fixedly connected between the bottom end of the top frame and the bottom frame, wherein the axial direction of the bottom frame is perpendicular to the vibration direction of the first screening plate 3. Under the elastic force of the telescopic spring, the top frame and the bottom frame can be telescoped and changed, so that when the first screening plate 3 drives the second screening plate 12 to reciprocate horizontally through the telescopic frame 5, interference with the vertical movement of the second screening plate 12 is avoided, and the second screening plate 12 is convenient to move up and down to cooperate with the first screening plate 3 to form a crushing effect on the agglomerated raw materials, thereby improving the screening effect of the raw materials.

[0028] The first screen plate 3 and the second screen plate 12 are parallel to each other, wherein the axial direction of the sliding groove 6 forms an acute angle with the vibration direction of the first screen plate 3 .

[0029] The screening aperture of the second screening plate 12 is larger than the screening aperture of the first screening plate 3, wherein the minimum distance between the second screening plate 12 and the first screening plate 3 is smaller than the screening aperture of the second screening plate 12, so as to facilitate the second screening plate 12 to pass through the agglomerated raw materials and the subsequent crushing effect.

[0030] Buffer springs 8 are fixedly connected at both ends of the sliding groove 6. The buffer spring 8 is suspended at one end away from the sliding groove 6. The buffer spring 8 forms a protective effect on the reciprocating motion of the sliding block 7, effectively preventing the sliding block 7 from colliding with the two ends of the sliding groove 6 and causing damage.

[0031] The linkage structure includes a linkage block 10 and a linkage spring 11. A linkage groove 9 is provided on the sliding block 7, wherein the linkage groove 9 is axially coaxially arranged with the sliding groove 6. The linkage block 10 is slidably connected in the linkage groove 9, and the two ends of the linkage block 10 are fixedly connected with the two ends in the linkage groove 9 in a one-to-one correspondence with the linkage spring 11. Multiple linkage blocks 10 are fixedly connected to both sides of the second screen plate 12. With the cooperation of the linkage block 10 and the linkage spring 11, when the second screen plate 12 moves downward along the sliding groove 6, under the action of the inertia of the second screen plate 12, the linkage spring 11 below is compressed, so that the second screen plate 12 can continue to move downward, thereby improving the crushing effect of the second screen plate 12 on the agglomerated raw materials on the first screen plate 3.

[0032] The operating principle of the present invention is now described as follows:

[0033] When in use, water-soluble fertilizer raw materials are put into the upper hopper 13, and the raw materials fall onto the first screening plate 3 through the second screening plate 12. The vibration motor 2 is started, and the vibration motor 2 drives the first screening plate 3 to vibrate back and forth, thereby forming a vibration screening of the raw materials. The raw materials that meet the particle size pass through the first screening plate 3 and fall into the material receiving box 14;

[0034] At the same time, when the first screen plate 3 reciprocates, the second screen plate 12 is driven to reciprocate along the sliding groove 6 through the telescopic frame 5 and the linkage structure. When the second screen plate 12 moves downward along the sliding groove 6, the second screen plate 12 and the first screen plate 3 approach each other, thereby forming an extrusion and crushing effect on the raw materials on the first screen plate 3, thereby further improving the crushing and screening effect of the raw materials.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
