[0002] The crusher is a machine that crushes solid raw materials of large size to the required size. The crusher is composed of coarse crushing, fine crushing, air conveying and other devices to achieve the purpose of high-speed impact. The traditional screening process is cancelled by using wind energy to make powder at one time. It is mainly used in mining, building materials and other industries.

[0003] The insecticide raw material crushing device with anti-splashing function disclosed in Chinese patent CN118788454A can effectively prevent insecticide raw materials from splashing during the crushing process, reduce waste of insecticide raw materials and environmental pollution, and extrude the rotating door by the gravity of the insecticide raw materials, the rotating door drives the rotating column and the second connecting rod to rotate and move, the rotating column rotates to drive the first gear to rotate and extrude the auxiliary rack spring plate, when the insecticide raw materials fall into the crushing device shell, the extrusion gravity of the rotating door disappears, the spring plate resets to drive the rotating door to rotate to close the opening of the crushing device shell. The automatic door design can keep the inside of the device relatively closed during non-feeding time.

[0004] The above-mentioned crushing device, in the process of use, the raw materials will accumulate under the crushing cutter when the crushing cutter is crushing the raw materials in the crushing device. Due to the over-thick accumulation of raw materials or the too large particle size, the cutter will be difficult to completely crush, resulting in incomplete crushing of part of the raw materials. In the process of crushing, the crushing cutter will throw the adhesive raw material slag to the inner wall of the device for adsorption, which is very difficult to clean, and frequent shutdown for cleaning may be required, increasing the maintenance cost.

[0020] First, the raw materials enter the crushing assembly, and the two crushing rollers are driven by the control member to crush the raw materials once. After the first crushing, there are residual raw materials in the crusher. The reciprocating assembly is driven to operate by the power transmission between the control member and the reciprocating assembly, so as to drive the scraping plate to move upward in the crusher, and at the same time, the uncrushed raw materials are simultaneously moved upward, and the raw materials adhered to the two side walls in the crusher are scraped off, so as to drive the raw materials in the scraping plate to enter the top of the two crushing rollers, and the raw materials are crushed twice by the two crushing rollers.

[0022] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0023] 1. Through the power transmission between the control components and the reciprocating assembly, the raw materials adhering to the inner walls of the crusher are scraped off, thereby driving the raw materials in the scraper into the top of the two crushing rollers.

It can effectively remove the material residue adhering to the inner wall of the crusher, prevent the material from accumulating due to adhesion, thereby avoiding the material from scaling or hardening on the inner wall, improving the material discharge efficiency, and avoiding resource waste.

[0024] 2. When the carrier frame moves downward along the limit track to reset, the elastic element inside the mounting sleeve will cause the limit slide column to slide from the top of the scraping chute into the receiving chute under the action of the drop. As the carrier frame gradually begins to slide, the scraping plate will rotate along the carrier frame. One end of the scraping plate will be lifted up and will no longer contact the inner wall of the crusher, thus avoiding the return of raw materials. This ensures that the particle size of the crushed material is more uniform, which can improve production efficiency, ensure product quality, and reduce equipment maintenance costs.

[0025] 3. The driven turntable drives the half-tooth collar on one side to rotate, and the half gear fixed inside the half-tooth collar rotates together. The half gear meshes with the reciprocating gear between the half-tooth collar and the half gear, driving the reciprocating gear to rotate back and forth. The scraper with intermittent reciprocating motion can periodically remove the material attached to the inner wall of the crusher, avoiding the material from accumulating for a long time and clogging the screen holes or discharge port. This can ensure that all materials can fully participate in the crushing process, thereby improving the overall crushing efficiency. Attached Figure Description

[0041] Power transmission between the reciprocating assembly and the control member.

[0042] Specifically, the raw materials enter the crushing assembly, and the two crushing rollers 101 are driven by the control member to crush the raw materials once, after the first crushing, the raw materials remaining in the crusher 100 (the remaining raw materials are the raw materials remaining due to not meeting the screening of the grid filter plate and the raw materials thrown off on the inner wall of the crusher 100 in the crushing process), the reciprocating assembly is driven to operate by the power transmission between the control member and the reciprocating assembly, so as to drive the scraping plate 202 to move upward in the crusher 100, and at the same time, the raw materials in the scraping plate 202 are synchronously moved upward, and the raw materials adhered to the two side walls of the crusher 100 are scraped, so that when the raw materials in the scraping plate 202 enter the upper half of the two crushing rollers 101, they have a tendency to move inward, which can increase the probability of entering the crushing rollers 101, and the raw materials are crushed twice by the two crushing rollers 101, when the scraping plate 202 moves to the top of the inner cavity of the crusher 100, the reciprocating assembly drives the scraping plate 202 to move downward, at this time, the scraping plate 202 does not contact the inner wall of the crusher 100, so as to avoid that the scraping plate 202 brings the raw materials back.

[0043] The raw materials adhered to the two side walls in the crusher 100 are scraped off through power transmission between the control member and the reciprocating assembly, so as to drive the raw materials in the scraping plate 202 into the top of the two crushing rollers 101, and the raw materials (here, the raw materials are the raw materials remaining due to not meeting the screening of the grid filter plate and the raw materials thrown off on the inner wall of the crusher 100 in the crushing process) in the scraping plate 202 are subjected to secondary crushing by the two crushing rollers 101, so as to ensure that all materials meet the required particle size requirement, reduce the mixing of coarse particles into the final product, thereby improving the uniformity and quality of the product, and effectively remove the material debris attached to the inner wall of the crusher 100, prevent the material from being accumulated due to adhesion, thereby avoiding the scaling or hardening of the material on the inner wall, improving the discharge efficiency of the material, and avoiding resource waste.

[0044] Embodiment 2: Reference Figures 1-5 and Figure 8 The second embodiment of the present application provides a crushing device, the top end of the crusher 100 is fixedly connected with the feed inlet 102, the bottom end of the crusher 100 is fixedly connected with the conical distribution frame 103, both sides of the conical distribution frame 103 are provided with the grid filter plate 104, the lower side of the grid filter plate 104 is provided with the fixed support 105, the fixed support 105 is fixedly connected on the crusher 100, and the fixed support 105 is slidably connected with the storage box 106.

[0045] Both ends of the scraping plate 202 are fixedly connected with the connecting baffle 203, one side of each of the two connecting baffles 203 is fixedly connected with the mounting sleeve 204, the mounting sleeve 204 is slidably connected with the limiting slide column 205, and an elastic element (in this embodiment, the elastic element is preferably a spring) is arranged between the mounting sleeve 204 and the limiting slide column 205. Within the elastic extension range of the elastic element, the mounting sleeve 204 can slide along the axis direction of the limiting slide column 205.

[0046] Both sides of the bearing frame 201 are provided with the fitting groove 206, the fitting groove 206 can be fitted with the mounting sleeve 204 below, the connecting baffle 203 is used for shielding the fitting grooves 206 on both sides to avoid the raw materials entering the inside of the bearing frame 201 from escaping through the fitting grooves 206, both sides of the inner wall of the crusher 100 are provided with the limiting track, the limiting track is composed of the scraping slide groove 207 and the storage slide groove 208, both the scraping slide groove 207 and the storage slide groove 208 are arc-shaped, used for limiting the limiting slide column 205 sliding in the slide groove, so that the sliding stroke of the limiting slide column 205 presents an arc shape, and a difference is arranged at the joint between the scraping slide groove 207 and the storage slide groove 208. The limiting slide column 205 is slidably connected in the limiting track.

[0047] The upper surface of the bearing frame 201 is fixedly connected with a fixed plate 209, sliding rails 210 are formed on the inner walls of the pulverizer 100, the fixed plate 209 is slidingly connected in the sliding rails 210, and one end of the fixed plate 209 penetrates through the sliding rail 210 on one side.

[0048] Specifically, the raw materials enter the pulverizer 100 through the feed port 102, are crushed by the crushing roller 101 in the pulverizer 100, and fall downward after passing through the crushing roller 101. The raw materials slide to both sides along the conical distribution frame 103 at the bottom of the pulverizer 100. The raw materials are filtered by the grid filter plate 104 below the crushing roller 101, so that the raw materials with a qualified crushing size fall through the grid filter plate 104 into the storage box 106 below for collection. The raw materials that are not completely crushed are screened out. When the reciprocating assembly drives the bearing frame 201 to slide along the limiting rail to the top of the inner cavity of the pulverizer 100, the limiting slide columns 205 at both ends of the scraping plate 202 slide along the scraping sliding groove 207.

As the bearing frame 201 gradually starts to slide, the scraping plate 202 rotates along the bearing frame 201, one end of the scraping plate 202 is lifted, and no longer comes into contact with the inner wall of the pulverizer 100. When the bearing frame 201 moves to the bottom end of the inner cavity of the pulverizer 100 along the limiting rail, the bearing frame 201 slides to the rear of the raw materials that are not completely crushed along the limiting rail. The elastic element again drives the limiting slide column 205 to slide from the bottom end of the storage sliding groove 208 to the scraping sliding groove 207. The steps are reversed and are sequentially reciprocated.

[0050] When the reciprocating assembly drives the bearing frame 201 to move downward along the limiting rail to reset, the elastic element in the mounting sleeve 204 causes the limiting slide column 205 to slide from the top end of the scraping sliding groove 207 to the storage sliding groove 208 under the action of the drop. As the bearing frame 201 gradually starts to slide, the scraping plate 202 rotates along the bearing frame 201, one end of the scraping plate 202 is lifted, and no longer comes into contact with the inner wall of the pulverizer 100. When the bearing frame 201 moves to the bottom end of the inner cavity of the pulverizer 100 along the limiting rail, the bearing frame 201 slides to the rear of the raw materials that are not completely crushed along the limiting rail. The elastic element again drives the limiting slide column 205 to slide from the bottom end of the storage sliding groove 208 to the scraping sliding groove 207. The steps are reversed and are sequentially reciprocated.
