This utility model discloses a wear-resistant hammerhead for a crusher, specifically relating to the field of hammerhead technology. It includes a hammer handle with a reinforcing connecting assembly. The reinforcing connecting assembly includes a hammerhead body located at one end of the hammer handle. A guide slope is formed at one end of the hammerhead body, and a reinforcing carbonized wear-resistant plate is welded onto the guide slope. This utility model uses the guide slope to ensure that the force point of the crushing action is concentrated at a specific location when the hammerhead body rotates, achieving more targeted crushing. Furthermore, the reinforcing carbonized wear-resistant plate and reinforcing chromium carbon strip improve the wear resistance of both the guide slope and the hammerhead body. The addition of a reinforcing side abutment plate positions the reinforcing carbonized wear-resistant plate welded onto the guide slope, preventing it from detaching and ensuring the stability of the reinforcing carbonized wear-resistant plate under stress during crushing.

This utility model relates to the field of road snow removal technology, specifically a snow and ice removal device for roads and bridges. It includes a snowplow, with a snow-scraping shell fixedly installed at its front end. A snow-scraping blade is rotatably mounted on the inner wall of the snow-scraping shell. A snow-shoveling device is located at the bottom of the snowplow, including a rotating shaft rotatably mounted at the bottom of the snowplow. A turntable is fixedly installed at the bottom end of the rotating shaft, and a mounting rod is fixedly installed near the outer bottom of the turntable. This utility model utilizes the periodic forward and backward movement of a sliding rod within an inclined sliding cylinder to allow the scraper to cut into the snow and ice layer with a downward impact force. Simultaneously, the rotating and crushing action of the blade, along with suction and throwing, forms a triple snow removal mechanism of "impact scraping - mechanical crushing - negative pressure cleaning." This reciprocating motion simulates the movement of a human hand shoveling snow, improving the scraper's efficiency in removing stubborn ice and snow, significantly reducing manual rework and the use of de-icing agents.

This utility model discloses a crusher, comprising: a crushing cup; a crushing hammer, which has a hammer shell and a counterweight located within the hammer shell; the hammer shell has an upper shell and a lower shell fixedly mounted thereon, the upper shell having an upper limit rib blocking the upper end of the counterweight, and the counterweight being located in the lower part within the hammer shell. The hammer shell is assembled from a split upper shell and lower shell, which can be injection molded, thus reducing manufacturing costs. The counterweight within the hammer shell serves two purposes: first, it increases the overall weight of the crushing hammer, utilizing gravitational potential energy to assist crushing, making operation easier; second, it lowers the center of gravity, causing the crushing hammer to generate a greater vertical impact force and a larger swing amplitude during descent, thus improving crushing efficiency. The upper limit rib within the upper shell blocks the upper end of the counterweight, keeping it fixed during crushing and ensuring smooth and precise crushing action.

This invention provides an energy-saving crushing device for recycling scrap metal, relating to the field of crushing device technology. It includes a base, with a housing fixedly connected to the upper surface of the base, an adjusting mechanism, and a limiting mechanism. The limiting mechanism is located inside a moving block, which has a transverse groove. Through the coordinated operation of the adjusting mechanism and the limiting mechanism, the device automatically triggers a pressure crushing action to address the problem of large or high-hardness metal blocks easily getting stuck. This avoids material blockage caused by the crushing roller jamming, and at the same time, prevents the drive motor from burning out due to overload operation, significantly reducing the equipment failure rate and extending the overall service life of the device. Furthermore, the limiting mechanism can stably limit the position of the adjusting structure, preventing it from sliding randomly due to material compression, ensuring the spacing accuracy of the crushing structure in conventional crushing operations, and ensuring consistent crushing effects for different batches of scrap metal.

This invention discloses a feeding device for the production of hydroxyapatite powder, aiming to solve the problems of uneven feeding, clogging, and dust pollution caused by the poor flowability and easy agglomeration of this type of powder. The device includes a frame, a feeding channel, a crushing device and a dust removal assembly located within the channel. The crushing device includes a fixed rod and a movable crushing shovel driven by a drive assembly, effectively preventing material bridging and agglomeration through active, reciprocating crushing action. The dust removal assembly includes a suction chamber, a filter screen, and a cleaning roller brush. When the crushing shovel moves, this mechanism can be periodically actuated, driving the cleaning roller brush to automatically clean the dust accumulated on the filter screen. This invention cleverly combines active crushing with a mechanically linked self-cleaning dust removal function, eliminating the need for an additional power source for the cleaning function. Its compact structure enables uniform, stable, and dust-free feeding, effectively improving production efficiency and environmental quality.

The application discloses an environment-friendly sand making system for mines, which is provided with a feeding hopper, a belt conveyor and a compression crusher. The discharging action of the feeding hopper, the conveying action of the belt conveyor and the crushing action of the compression crusher are linkage performed in the same period. A first linkage member is arranged on the side of the control roller at the feeding end, and a second linkage member is arranged close to the control roller at the discharging end. The control roller rotates to perform the conveying action of the belt conveyor, and drives the control material assembly to perform the opening and closing action through the first linkage member and drives the movable jaw plate to reciprocate through the second linkage member. In the application, the control material assembly is periodically opened and closed to control the step-by-step discharging of the sand and stone in the feeding hopper, so that the material conveying amount per unit time is reduced. The crushing action of the compression crusher is performed on the quantitative stone each time, and the crushed stone amount each time is controlled, so that the compression crusher is prevented from being blocked, and the sand making system is continuously, effectively and stably performed.

This invention discloses an integrated soil loosening and fertilizing machine for landscape gardening, relating to the technical field of integrated soil loosening and fertilizing machines. It includes a frame, a push handle, and wheels. The push handle is fixed to the rear end of the frame, and the wheels are rotatably connected to the front end of the push handle. It also includes a hopper, a disc, and a second component. Through the coordinated design of the second and third components, the generation of fine powder can be effectively reduced, breaking the vicious cycle of "broken fertilizer—sticking to the wall—re-clogging." Existing rotating mixing structures continuously disturb the flow, easily generating a large amount of fine fertilizer powder. This fine powder is highly adhesive and easily adheres to the hopper wall, further exacerbating material accumulation, agglomeration, and secondary clogging. This design eliminates forced mixing and crushing actions, using vertical piercing and horizontal loosening to break up bridging and rat holes throughout the process. It does not grind and generate fine powder materials, reducing fertilizer sticking to the wall and solidifying at the source, breaking the vicious cycle problem caused by traditional mixing structures, making the hopper discharge cleaner and smoother, and preventing material residue accumulation during long-term operation.
