A vertical crusher for producing biological organic fertilizer

Abstract

The present invention relates to a vertical pulverizer for producing bio-organic fertilizer, which is related to the field of bio-organic fertilizer crushing equipment. The vertical cylinders are evenly distributed and the ring cutting knives are located between the gaps of the vertical cylinders. When the fertilizer is crushed, the ring cutting knives located between the gaps between the adjacent vertical cylinders cooperate with the gaps between the adjacent vertical cylinders to centrifugally cut the bio-organic fertilizer, thereby having a good crushing effect on plate-like and strip-shaped organic fertilizers. In addition, the centrifugal force generated by the blades centrifugally spreads the crushed organic fertilizer, so that the organic fertilizer is evenly spread on the screen, with a larger screening area. At the same time, the rotating screening of the screen reduces the local accumulation of fertilizer on the screen, improves the screening speed and reduces the occurrence of screen blockage.

Description

Technical Field

[0001] The invention relates to the field of bio-organic fertilizer production, and more specifically to a vertical crusher for bio-organic fertilizer production. Background Art

[0002] Bio-organic fertilizer is a special type of fertilizer, which is composed of specific functional microorganisms and organic materials mainly derived from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) that have been harmlessly treated and decomposed. This fertilizer has the dual effects of microbial fertilizer and organic fertilizer, which can improve soil structure, increase soil fertility, and promote healthy plant growth. In the processing of bio-organic fertilizer, crushing is an important link.

[0003] The main purpose of crushing is to reduce the particle size of organic materials, thereby increasing their contact area with the soil. This can not only increase the dissolution rate and absorption efficiency of fertilizers, making it easier for crops to absorb nutrients, but also make the fertilization effect more lasting and enhance the drought resistance and disease resistance of crops. In addition, the volume of crushed organic fertilizers is reduced and the weight is lightened, which is convenient for transportation and storage. It is also beneficial to subsequent mixing, granulation and other process operations.

[0004] Existing bio-organic fertilizer crushing devices face significant challenges when processing fertilizers: the crushing effect is not satisfactory for agglomerated and long rod-shaped fertilizers, and they can often only be partially crushed, resulting in fertilizer particles of different sizes, which not only affects the uniformity of the fertilizer, but also increases the wear rate of the blades.

[0038] Specifically, when the bio-organic fertilizer is crushed, the bio-organic fertilizer is put into the feeding hopper 2, and the second motor 20 is started. The second motor 20 drives the prism shaft 19 to rotate, and the prism shaft 19 drives the ring cutter 6 to rotate through the center ring 601. The ring cutter 6 located in the gap between each adjacent vertical cylinder 5 cooperates with the gap between the adjacent vertical cylinders 5 to centrifugally cut the bio-organic fertilizer, thereby having a good crushing effect on the plate-like and strip-shaped organic fertilizer.

[0039] See also Figure 4 The scissor-type telescopic rod 9 includes a plurality of pairs of connecting rod groups hinged at the head and tail ends and distributed in an X shape, the connecting rod group includes a pair of connecting rods hinged in the middle, the connecting rod 8 is fixed at the hinged position in the middle of the connecting rod group, the sliding frame 14 is provided with an arc-shaped slide groove 1401 for the mounting ring 603 to be nested and slid on the side facing the mounting ring 603, the sliding frame 14 is provided with a strip slide groove 1402 on the side facing the scissor-type telescopic rod 9, a pair of support rollers 15 are nested in the strip slide groove 1402 and connected to the strip slide groove in a longitudinal sliding manner, and the pair of support rollers 15 are respectively installed at the end hinged positions of the connecting rod group.

[0040] Specifically, when the scissor-type telescopic rod 9 of the gap adjustment component 7 is being extended and retracted, the vertical cylinder 5 and the circular cutting knife 6 have good stability, thereby improving the cutting effect on the plate-lump fertilizer and the strip-shaped fertilizer.

[0041] See also Figure 4 and Figure 5 The front and rear ends of the sliding frame 14 are fixedly connected with a sliding arm 1403 integrally formed therewith, and the side wall of the sliding groove frame 13 is provided with a vertical sliding groove for the sliding arm 1403 to slide vertically.

[0043] See also Figure 5 The blade 602 is a strip-shaped blade with a diamond-shaped cross section and blade portions at both horizontal ends.

[0044] Specifically, it has a better crushing and cutting effect on fertilizer plate agglomerates and strip-shaped fertilizers.

[0046] Specifically, the screen 4 is rotated in a direction opposite to the rotation direction of the blade 602, thereby improving the fertilizer spreading speed and screening effect.

[0047] See also Figure 6 and Figure 7 The bottom of the vertical cylinder 5 at the lowest end is fixedly connected to a bottom cylinder 16, and a lifting cylinder 17 is nested in the bottom cylinder 16 and is vertically slidably sleeved on the outside of the prism shaft 19. Both the bottom cylinder 16 and the lifting cylinder 17 are cylinders with T-shaped cross-sections. A sliding column 18 is fixedly connected to the lower part of the lifting cylinder 17, and a guide groove 1601 is provided in the inner arm of the bottom cylinder 16 for the sliding column 18 to slide.

[0048] Specifically, the lifting cylinder 17 blocks the vertical cylinder 5 at the bottom, and when the prism shaft 19 drives the lifting cylinder 17 to rotate, the sliding column 18 slides in the guide groove 1601, thereby driving the lifting cylinder 17 to move up and down in the vertical cylinder 5, and lifting the organic fertilizer accumulated in the bottom vertical cylinder 5 to the cutting gap above, so that the fertilizer falling into the crushing mechanism 3 is fully crushed and cut.

[0049] In this embodiment, the guide groove 1601 is an obliquely arranged elliptical groove or a circumferentially distributed wave groove.

While accelerating the screening, the fertilizer blocks intercepted by the screen holes are centrifugally pushed, so that the intercepted fertilizer blocks move to the upper edge of the screen 4. The scraper 23 drives the rolling roller 24 to roll and crush the fertilizer blocks accumulated on the upper edge of the screen 4, so that the intercepted fertilizer blocks are broken, avoiding the clogging of the screen 4 by the intercepted fertilizer blocks and performing secondary crushing at the same time, so that the fertilizer is more fully crushed.

[0053] See also Fig. 9 and Fig.10 A sliding block 25 is rotatably connected to the inner side of the rolling roller 24 . The sliding block 25 is nested inside the end of the scraper 23 and penetrates a guide rod 26 installed in the scraper 23 .

[0054] Specifically, the rolling roller 24 can float up and down as the scraper 23 makes a circular motion, so as to adapt to the squeezing and crushing of fertilizer blocks of different sizes and improve the effect of the rolling roller 24 rotating and crushing.

[0055] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto.
