Description

Technical Field

[0001] This utility model relates to the field of agricultural planting, and in particular to an agricultural planting fertilizer crushing device. Background Technology

[0002] An existing patent (publication number: CN222035068U) discloses an agricultural fertilizer crushing device. It includes a crushing box with a feeding hopper at the top and a discharge port on the lower side wall. Inside the crushing box is a crushing mechanism for crushing the added fertilizer, and below this mechanism is a screening mechanism for sieving the crushed fertilizer. The screening mechanism is connected to the crushing mechanism. The crushing mechanism includes three crushing shafts running through the crushing box, with the middle shaft located below the two side shafts. However, this device has "crushing blades spaced apart on the crushing shafts." Since the device relies on these blades inside the crushing box to crush the fertilizer, when crushing larger pieces of fertilizer, the blades may be subjected to heavy loads, leading to accelerated wear and affecting the device's lifespan. Summary of the Invention

[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing an agricultural fertilizer crushing device that uses crushing blades inside a crushing chamber to crush fertilizer. Simultaneously, a drive motor at the front of the crushing chamber rotates a cam, causing the cam to lift and lower a linkage frame while repeatedly moving two sets of crushing platforms inside the crushing chamber. This allows the two sets of crushing platforms to initially crush larger pieces of fertilizer before feeding them into the crushing chamber for further crushing. This avoids the crushing blades inside the crushing chamber handling larger pieces of material, thereby increasing the equipment's lifespan.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] An agricultural fertilizer crushing device includes a crushing box, support legs, a drive shaft, a guide rod, a limit switch, a linkage frame, a linkage frame guide rod, and a drive shaft. The lower part of the crushing box is fixedly connected to the support legs. The crushing box has a crushing shaft groove inside, which is adapted to the crushing shaft. The crushing shaft is connected to the crushing shaft and rotates inside the crushing shaft groove. The rear part of the crushing box is fixedly connected to a crushing motor. The output shaft of the crushing motor is fixedly connected to the crushing shaft. The side of the crushing shaft is fixedly connected to a crushing blade. The lower part of the crushing box has a filter screen groove, which is connected to... The filter screen is adapted to the filter screen groove, and the filter screen is inserted into the filter screen groove. The front of the crushing box and the front of the filter screen are both fixedly connected to the bolt platform. The two sets of bolt platforms are connected by bolts. The upper part of the crushing box is fixedly connected to the crushing box. The inside of the crushing box is connected to the inside of the crushing box. The crushing box has a crushing table slide groove, which is adapted to the crushing table. The crushing table slide groove is connected to the crushing table, and the crushing table slides inside the crushing table slide groove. The surface of the crushing table has crushing teeth, and the side of the crushing table has a drive shaft. The upper part of the crushing box has a drive shaft positioning groove.

[0006] The drive shaft positioning groove is adapted to the drive shaft and is connected to the drive shaft. The drive shaft slides inside the drive shaft positioning groove. The rear part of the drive shaft is fixedly connected to the guide seat, and the front part of the drive shaft is fixedly connected to the drive seat. The side parts of the guide seat and the side parts of the drive seat are both fixedly connected to the guide rod. The side of the crushing box is fixedly connected to the guide frame. The guide frame is adapted to the guide rod and is connected to the guide rod. The guide rod slides inside the guide frame.

[0007] The rear part of the guide rod is fixedly connected to the limit position, which is connected to the inside of the guide frame through a return spring. The upper part of the crushing box is fixedly connected to the feed hopper. The side part of the linkage frame is fixedly connected to the positioning shaft of the linkage frame. The transmission seat has a transmission rod inside. The front part of the support rod is rotatably connected to the transmission rod. The rear part of the support rod is rotatably connected to the positioning shaft of the linkage frame. The inside of the linkage frame is rotatably connected to the support roller. The side of the crushing box is fixedly connected to the guide seat of the linkage frame. Beneficial effects

[0008] 1. In the operation of this agricultural fertilizer crushing equipment, the fertilizer is crushed by the crushing blades inside the crushing box. In conjunction with the drive motor at the front of the crushing box, the cam is driven to rotate, which in turn drives the linkage frame to rise and fall. At the same time, the cam drives the two sets of crushing tables inside the crushing box to move repeatedly. This allows the two sets of crushing tables to initially crush larger pieces of fertilizer before feeding them into the crushing box for further crushing. This avoids the crushing blades inside the crushing box processing larger pieces of material, thereby increasing the service life of the equipment.

[0009] 2. During the use of this utility model agricultural fertilizer crushing equipment, the fertilizer is sieved through the filter screen at the bottom of the crushing box. If the filter screen is damaged, the filter screen can be removed from the equipment and replaced by disassembling the bolts on the side of the two sets of bolt platforms, which further facilitates personnel maintenance.

[0010] 3. During the use of this utility model agricultural fertilizer crushing equipment, the drive motor at the front of the crushing box drives the cam to rotate, which in turn drives the linkage frame to lift and lower. In conjunction with the two sets of support rollers inside the linkage frame rotating at the bottom of the cam, the cam is prevented from directly contacting the linkage frame and causing wear, thereby further increasing the service life of the equipment.
