Description

Technical Field

[0001] The utility model belongs to the technical field of crushing devices, in particular to a crushing device with a pre-processing structure. Background Art

[0002] A crushing device is a device used to reduce the particle size or pulverize materials (such as ores, chemicals, plants, foods, etc.). It uses mechanical forces such as impact, compression, and shear force to break up large pieces of material into fine particles. According to the working principle and application field, crushing devices can be divided into many types, including hammer mills, ball mills, air flow mills, blade mills, etc. Although existing crushing devices can achieve the crushing of materials, there are still shortcomings. For example, when crushing materials, due to the differences in the size of the materials themselves, the existing crushing devices may not be able to ensure the uniformity of the particles when processing the materials, affecting the quality of subsequent processing. The conventional response method is to pre-treat the material through screening and other methods to achieve more uniform material properties for better crushing. However, the disadvantage of this method is that when there are multiple particle sizes in the material, smaller particles may be blocked by larger particles in the sieve holes. Material blockage will cause the screen to be unable to continuously screen the material, reducing work efficiency. Therefore, a new structure is proposed to solve the above problems. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention aims to provide a crushing device with a pre-processing structure.

[0004] The utility model is realized by the following technical solution: a crushing device with a pre-processing structure, comprising: a device housing, a baffle frame and a screening mechanism, a feed hopper is provided on the top of the device housing, a baffle frame is provided in the center of the device housing, and docking posts are provided at the four corners of the top of the baffle frame;

[0005] Each set of docking column shells is movably sleeved with a set of vibration springs, the top of the docking column is recessed downward to form a rotation groove, an inner screw groove is opened inside the rotation groove, and a screening mechanism is provided above the baffle frame, the screening mechanism consisting of an outer frame and a screen;

[0006] There are four groups of docking holes at the four corners of the top of the screening mechanism. A group of screws is provided above each group of docking holes. A knob is provided on the top of each group of screws. The outer side of the screw is provided with a thread matching the specifications of the inner screw groove. The mesh diameter of the screen is 0.5 cm.

[0007] As a preferred embodiment, a crusher body is provided below the device housing, the bottom of the device housing is connected to the top of the crusher body, the bottom of the feed hopper is connected to the top of the device housing, and the side of the baffle is welded and fixed to the inner wall of the device housing.

[0008] As a preferred embodiment, the baffle frame and the screening mechanism are both square structures, the top of the baffle frame is welded and fixed to the bottom of the docking column, the top of the baffle frame is glued and fixed to the bottom of the vibration spring, and the height of the docking column matches the depth of the docking hole.

[0009] As a preferred embodiment, the radius length of the docking hole matches the radius length of the docking column, the radius length of the docking hole matches the radius length of the screw, and the radius length of the screw matches the radius length of the rotary groove.

[0010] As a preferred embodiment, the length of the screw is greater than the depth of the rotary groove, the depth of the rotary groove is less than the height of the docking column, the top of the screw is glued and fixed to the bottom of the knob, and the radius length of the knob is greater than the radius length of the rotary groove. By rotating the screw and the rotary groove, the screening mechanism can be restricted above the baffle frame to prevent the screening mechanism from falling off the docking column when vibrating, and at the same time facilitate the installation and disassembly of the screening mechanism.

[0011] As a preferred embodiment, the thickness of the baffle frame is smaller than the thickness of the screening mechanism, a hollow opening 1 is provided at the center of the baffle frame, a hollow opening 2 is provided at the center of the screening mechanism, a screen is welded on the inside of the hollow opening 2, and the length and width of the screen are smaller than the length and width of the hollow opening 1. When the material impacts the screening mechanism downward, the screening mechanism moves downward under the action of the impact force and squeezes the four groups of vibration springs. Due to the action of the elastic force, the four groups of vibration springs rebound immediately after being squeezed and are squeezed again after rebounding, so that the four groups of vibration springs repeatedly contract and stretch, and then drive the screening mechanism to vibrate repeatedly along the four groups of docking columns, so that the material gathered at the mesh can be vibrated out, preventing the material from being blocked at the mesh and affecting the normal use of the screen, thereby ensuring that the screen can continue to screen.

[0012] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: by setting the baffle frame, docking column, vibration spring, screening mechanism, screw and knob, the docking holes at the four corners of the top of the screening mechanism respectively pass downward through the four groups of docking columns on the top of the baffle frame, so that the four corners of the bottom of the screening mechanism respectively contact the top of the four groups of vibration springs. At this time, the top of the screening mechanism is higher than the top of the docking column, and then the four groups of screws are rotated into the rotation grooves opened on the top of the four groups of docking columns by rotating the four groups of knobs, so that the screws and the rotation grooves are rotationally connected, and the screening mechanism moves downward under the pressure of the bottom of the knob, thereby squeezing the vibration spring to compress and store force. Therefore, the screening mechanism is installed above the baffle frame. When the material falls to the top of the screen, the screening mechanism squeezes the vibration spring to repeatedly stretch and compress the vibration spring, thereby causing the screening mechanism to vibrate repeatedly, thereby preventing the material from clogging the screen holes, so that the screen can continuously screen the material, improve the screening effect of the material, and thus improve the pre-treatment effect of the material. At the same time, the rotation connection between the screw and the rotation groove facilitates the disassembly and installation of the screening mechanism, thereby facilitating the maintenance of the screening mechanism.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] See also Figures 1 to 5 A crushing device with a pre-processing structure includes: a device housing 100, a baffle 120 and a screening mechanism 200. A feed hopper 110 is provided on the top of the device housing 100, a baffle 120 is provided in the center of the device housing 100, and docking posts 130 are provided at the four corners of the top of the baffle 120;

[0023] Each set of docking posts 130 is movably sleeved with a set of vibration springs 140. The top of the docking posts 130 is recessed downward to form a screw groove 131. An inner screw groove is formed inside the screw groove 131. A screening mechanism 200 is provided above the retaining frame 120. The screening mechanism 200 consists of an outer frame and a screen 220.

[0024] Four groups of docking holes 230 are provided at the four corners of the top of the screening mechanism 200. A group of screws 211 are provided above each group of docking holes 230. A knob 210 is provided on the top of each group of screws 211. The outer side of the screw 211 is provided with a thread matching the specifications of the inner screw groove. The mesh diameter of the screen 220 is 0.5 cm.

[0025] A crusher body is provided below the device housing 100 , the bottom of the device housing 100 is connected to the top of the crusher body, the bottom of the feed hopper 110 is connected to the top of the device housing 100 , and the side of the baffle 120 is welded and fixed to the inner wall of the device housing 100 .

[0026] The baffle frame 120 and the screening mechanism 200 are both square structures. The top of the baffle frame 120 is welded to the bottom of the docking column 130 , and the top of the baffle frame 120 is glued to the bottom of the vibration spring 140 . The height of the docking column 130 matches the depth of the docking hole 230 .

[0027] The radius of the docking hole 230 matches the radius of the docking column 130 , the radius of the docking hole 230 matches the radius of the screw 211 , and the radius of the screw 211 matches the radius of the rotary groove 131 .

[0028] The length of the screw 211 is greater than the depth of the rotary groove 131, and the depth of the rotary groove 131 is less than the height of the docking column 130. The top of the screw 211 is glued and fixed to the bottom of the knob 210. The radius length of the knob 210 is greater than the radius length of the rotary groove 131. By rotating the screw 211 and the rotary groove 131, the screening mechanism 200 can be restricted above the baffle frame 120 to prevent the screening mechanism 200 from falling off the docking column 130 when vibrating, and at the same time facilitate the installation and disassembly of the screening mechanism 200.

[0029] The thickness of the baffle frame 120 is smaller than the thickness of the screening mechanism 200. A hollow opening 1 is opened in the center of the baffle frame 120, and a hollow opening 2 is opened in the center of the screening mechanism 200. A screen 220 is welded on the inside of the hollow opening 2. The length and width of the screen 220 are smaller than the length and width of the hollow opening 1, ensuring that the baffle frame 120 will not hinder the falling of the screened material.

[0030] Example 1: Please refer to Figures 1 to 5 In actual use, first pick up the screening mechanism 200, align the docking holes 230 at the four corners of the top of the screening mechanism 200 with the four groups of docking posts 130 on the top of the retaining frame 120, then move the screening mechanism 200 downward so that the four groups of docking posts 130 pass upward through the four groups of docking holes 230, thereby placing the screening mechanism 200 on the top of the retaining ring, so that the four corners of the bottom of the screening mechanism 200 are in contact with the tops of the four groups of vibration springs 140 respectively. At this time, the top of the screening mechanism 200 is higher than the top of the docking posts 130, then pick up the four groups of knobs 210 and the four groups of screws 211 respectively, and rotate the four groups of knobs 210 respectively, so that the knobs 210 drive the screws 211 to rotate inside the rotary grooves 131, thereby respectively 1 is rotated into the four sets of rotary grooves 131. When the screw rods 211 are rotationally connected to the rotary grooves 131, the knob 210 moves downward and squeezes the top of the screening mechanism 200, so that the top of the screening mechanism 200 moves downward and squeezes the four sets of vibration springs 140, so that the four sets of vibration springs 140 are compressed and stored. After the four sets of screw rods 211 are completely rotated into the four sets of rotary grooves 131, the installation of the screening mechanism 200 is completed. Similarly, if you want to remove the screening mechanism 200, rotate the knob 210 in the opposite direction according to the above steps to disconnect the four sets of screw rods 211 from the four sets of rotary grooves 131 respectively, so that the screening mechanism 200 can be removed. The final effect is to facilitate the disassembly and installation of the screening mechanism 200, thereby facilitating the maintenance of the screening mechanism 200.

[0031] Example 2: Please refer to Figure 1, pour the material to be processed into the feed hopper 110, the material falls downward along the inside of the feed hopper 110 into the inside of the device housing 100, and then continues to fall downward to the top of the screen 220. The screening mechanism 200 is installed above the retaining frame 120 at this time, and the four sets of vibration springs 140 are in a compressed state. When the material impacts the screening mechanism 200 downward, the screening mechanism 200 moves downward under the action of the impact force and squeezes the four sets of vibration springs 140. Due to the action of the elastic force, the four sets of vibration springs 140 rebound immediately after being squeezed, and are squeezed again after rebounding, thereby causing the four sets of vibration springs 140 to repeatedly contract and stretch, and then The screening mechanism 200 is driven to vibrate repeatedly along the four groups of docking columns 130, so that the materials gathered at the mesh holes can be vibrated out, preventing the materials from being blocked at the mesh holes and affecting the normal use of the screen 220, ensuring that the screen 220 can continue to screen. Since the device housing 100 is installed on the top of the grinder body, vibration will be generated when the grinder body is working. The vibration is transmitted to the inside of the device housing 100, which will assist the vibration of the screening mechanism 200. The materials that fall on the outer frame will be taken out along with the screening mechanism 200 when the screening mechanism 200 is disassembled, and the materials blocked at the top of the screening mechanism will be recycled at the same time, saving resources.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
