Description

Technical Field

[0001] The utility model relates to the field of fertilizer preparation, in particular to a raw material crushing device for fertilizer preparation. Background Art

[0002] Organic fertilizer raw materials tend to clump during storage, which requires them to be crushed again before use.

[0003] At present, the traditional crushing device includes an open cylinder with a crushing knife inside. When in use, the raw materials are poured into the cylinder, the crushing knife is started to crush the raw materials, and after the crushing is completed, the raw material mechanism is taken out. This crushing device cannot work continuously. Moreover, due to the different manufacturing methods of the crushing head, in many cases there is a large gap between the side of the crushing knife and the cylinder, resulting in the surface actually used for crushing being smaller than the actual designed crushing surface, resulting in incomplete and uneven crushing, thereby reducing the crushing efficiency.

[0004] In order to solve the above problems, we proposed a raw material crushing device for fertilizer preparation. Utility Model Content

[0005] In order to solve the problem that the crushing head of the crusher is not suitable for large-scale feeding and discharging, which affects the crushing efficiency, the utility model proposes a raw material crushing device for fertilizer preparation, which crushes the raw materials by means of a crushing rod, can work continuously, and improves the processing efficiency.

[0007] Preferably, a discharge box is installed at the discharge port, and a discharge drawer is slidably connected to one side of the discharge box.

[0008] Preferably, a rim is provided at one end of the screening cylinder and the crushing cylinder close to each other, the rims of the two are fixedly connected by bolts, and a plurality of equal-diameter sieve openings for screening are provided on the circumferential conical wall.

[0009] Preferably, the upper portion of the pulverizing cylinder is provided with a feed port connected to the feed hopper, and the bottom of the feed hopper and the feed port are connected via an electromagnetic valve.

[0010] Preferably, the power source is one of a motor, a cylinder or a hydraulic cylinder that performs circumferential motion, and the power source is installed on one side of the box.

[0019] 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 of the embodiments.

[0020] like Figure 1-5As shown, a raw material crushing device for fertilizer preparation includes a box body 1 and a crushing structure. The box body 1 has a discharge port 101 at the bottom, and the crushing structure is inside the box body 1, including a horizontal crushing cylinder 3, a screening cylinder 4, which is arranged inside the box body 1, and the screening cylinder 4 is fixed on one side of the crushing cylinder 3, and the screening cylinder 4 and the crushing cylinder 3 are in a continuous conical structure, a feed hopper 2, which is arranged on the upper part of the box body 1 and is connected to the inside of the crushing structure, and the crushing cylinder 3 is evenly provided with horizontal grate bars 301 on the circumferential inner wall, and a crushing rod 5, which is horizontally adapted to the inside of the crushing cylinder 3 and the screening cylinder 4, and the crushing rod 5 includes a shaft body for rotation support, and the shaft body is provided with a crushing plate 6 with unequal diameter spirals, and the crushing plate 6 has a crushing groove 601, and the crushing groove 601 is evenly arranged around the unequal diameter spiral outer wall of the crushing plate 6 in a horizontal shape, and a power source 11 connected to the crushing rod 5.

[0021] The above-mentioned crushing rod 5 is provided with unequal diameter spiral crushing plates 6, the outer wall of the crushing plate 6 is evenly provided with crushing grooves 601, and the inner wall of the crushing tube 3 is evenly provided with grate bars 301. At the same time, it is explained that the arrangement direction of the grate bars 301 and the crushing grooves 601 is consistent, that is, they are arranged along the axial direction of the crushing rod 5. The spiral motion of the crushing plate 6 can generate a vertical tangential force on the material falling on the grate bars 301, thereby crushing the material.

[0022] Furthermore, the crushing cylinder 3 has a conical structure, and the screen cylinder 4 connected thereto also has a corresponding conical structure. The inside of the crushing cylinder 3 is provided with a spiral crushing plate 6 of unequal diameter that is adapted to the inner wall of the cylinder. The crushing plate 6 is arranged around the crushing rod 5, and the crushing rod 5 is horizontal. When the crushing rod 5 rotates, the crushing plate 6 makes a spiral motion toward one side of the screen cylinder 4, so as to push the crushed material into the screen cylinder 4.

[0023] In the utility model, a discharge box 7 is installed at the discharge port 101 , and a discharge drawer 10 is slidably connected to one side of the discharge box 7 . The crushed material comes out of the discharge port 101 and the discharge drawer 10 receives the material coming out of the discharge port 101 .

[0024] Furthermore, if Figure 2 As shown in Figure 3, the screening cylinder 4 and the crushing cylinder 3 are provided with a rim at one end close to each other, and the rims of the two are fixedly connected by bolts. A plurality of equal-diameter sieve openings for screening are provided on the circumferential conical wall. The sieve openings of equal diameter can adjust the sieve opening size according to the needs of technical personnel in the field, that is, the screening cylinder 4 can be replaced.

[0025] Furthermore, a feeding port connected to the feeding hopper 2 is provided on the upper portion of the pulverizing cylinder 3, and the bottom of the feeding hopper 2 and the feeding port are connected via an electromagnetic valve 9 for adjusting the feeding quantity.

[0026] Furthermore, the power source 11 is one of a motor, a cylinder or an oil cylinder that performs circumferential motion, and the power source 11 is installed on one side of the box body 1 .

[0027] It should be noted that a gap of 0.5 to 1.5 cm is uniformly left between the grate bars 301 and the unequal diameter spiral outer wall of the crushing plate 6 to ensure the crushing effect. Those skilled in the art can adjust this gap according to actual needs.

[0028] Furthermore, a protective door 8 for inspecting and replacing its internal components is provided on the side of the box body 1 away from the power source 11. A bearing seat is arranged inside the protective door 8. The side of the screening drum 4 away from the crushing drum 3 abuts against the bearing seat to generate rotation.

[0029] The working principle of the above utility model is: the raw material enters the grinding cylinder 3 from the feed hopper 2, the power source 11 drives the grinding rod 5 to rotate, the material falls on the grate bar 301 and is broken by the tangential force generated between the grinding plate 6 and the grate bar 301, and the crushed powder material can enter the bottom of the box body 1 through the screening cylinder 4, and then fall into the discharge box 7, and the crushed material can be received by the discharge drawer 10.

[0030] In addition, during the crushing process, the raw materials that fail to pass through the screening barrel 4 fall along the inclined inner wall of the screening barrel 4 onto the inclined inner wall of the crushing barrel 3 and are crushed again by the crushing plate 6 and the grate bars 301 until these materials can pass through the equal-diameter screen opening of the screening barrel 4, thereby greatly ensuring the crushing quality.

[0031] The components in the present invention are all common standard components or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
