AI Technical Summary
Existing gantry-type fertilizer feeders are prone to damage and leakage of fertilizer bags during the feeding process, and require farmers to precisely align the fertilizer bucket, which is physically demanding and reduces the user experience.
A gantry-type fertilizer feeder was designed, which employs a clamping mechanism and a lifting mechanism. The clamping mechanism holds the fertilizer bag by clamping blocks and locking blocks, and uses the weight of the fertilizer itself to maintain stability. The lifting mechanism controls the extension or retraction of the forearm by a hydraulic cylinder and a three-position four-port reversing valve to achieve automatic feeding.
It reduces damage and leakage of fertilizer bags, improves the stability of feeding and user experience, reduces the need for aligning fertilizer buckets, and reduces physical exertion.

Abstract
Claims
1. Portal-type top-dresser comprising a fixed tube (1), characterized in that: The outer wall of the fixed tube (1) is rotatably clamped with a clamping mechanism (2). The clamping mechanism (2) includes two handles (201). One end of the handle (201) is fixed with a fixed rod (202), and one end of the fixed rod (202) is fixed with a clamping block (203). One end of the other handle (201) is fixed with a support rod (204). One side of the support rod (204) is rotatably connected to one side of the fixed rod (202). One end of the support rod (204) is rotatably connected with a fixed rod (205). One end of the fixed rod (205) is rotatably connected with a support rod (206). One end of the support rod (206) is fixed with a clamping block (207). One side of the support rod (206) is rotatably connected to one side of the fixed rod (202). The fixed tube (1) is clamped at both ends by a lifting mechanism (3), the width of which is less than or equal to the length of the fixed tube (1); a spring (208) is fixed on one side of the support rod (204) and the fixed rod (205); a chain (209) is fixed at the rotatable connection between the support rod (204) and the fixed rod (205); a lifting frame (210) is fixed at one end of the chain (209); the inner wall of the lifting frame (210) is rotatably clamped to the outer wall of the fixed tube (1); the clamping block (207) is adapted to the clamping block (203).
2. The boom-type fertilizer applicator of claim 1, characterized in that: The clamping block (203) has a slot on one side, and one end of the locking block (207) is in contact with the inner wall of the slot on one side of the clamping block (203). The length of one end of the locking block (207) is equal to the length of the slot on one side of the clamping block (203), and the length of the support rod (204) is less than the length of the fixed rod (202).
3. The boom-type fertilizer applicator of claim 1, wherein: The lifting mechanism (3) is fixed with a mounting bracket (302). A hydraulic cylinder (303) is rotatably connected to the bottom of both sides of the inner wall of the mounting bracket (302). A large arm (304) is rotatably connected to the top of both sides of the inner wall of the mounting bracket (302). The bottom of the large arm (304) is rotatably connected to the output end of the hydraulic cylinder (303). Pins (305) are fixed to both sides of one end of the large arm (304), and the two pins (305) are rotatably connected to each other at opposite ends. There is a forearm (307), and two pins (305) are fixedly fitted with baffles (306) at the bottom. The baffles (306) are located at the bottom of the forearm (307). One end of the forearm (307) is fixed with a support tube (308). The inner walls of the two support tubes (308) are engaged with the outer walls of both ends of the fixed tube (1). The pins (305) are provided with several positioning holes. By selectively inserting the pins into different holes, the opening and closing of the forearm (307) can be adjusted.
