AI Technical Summary
Traditional fertilizer spreaders have fixed fertilizer spreading angles and widths, which makes it easy for fertilizer to be spilled into rivers or nearby fields, causing environmental pollution and waste of resources.
Design a fertilizer spreading width limiter for a fertilizer spreader, including a guide plate assembly, a pin, a tension spring, a hydraulic cylinder, a connecting frame, a track frame, and locking bolts. The angle of the guide plate is controlled by the extension and retraction movement of the hydraulic cylinder, thereby limiting the angle and width of fertilizer spreading.
It effectively limits the angle and width of fertilizer application, preventing fertilizer from being spread to non-target areas and reducing environmental pollution and resource waste.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of fertilizer spreader technology, and in particular to a fertilizer spreading width limiter for fertilizer spreaders. Background Technology
[0002] Fertilizer spreaders are agricultural machinery used to spread manure, chemical fertilizers, and other fertilizers onto fields. Traditional fertilizer spreaders spread fertilizer onto fields using a spreading disc, with a fixed spreading angle and width. This makes it easy to spill fertilizer into rivers or adjacent fields near riverbanks or field edges, leading to environmental pollution and resource waste. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a fertilizer spreading width limiter for a fertilizer spreader, which allows the fertilizer to move along the direction of the guide plate, thereby achieving the purpose of limiting the spreading angle and width of the fertilizer.
[0004] The technical solution of this utility model is implemented as follows: A fertilizer spreading width limiter for a fertilizer spreader includes a guide plate assembly, a pin, a tension spring, a hydraulic cylinder, a connecting frame, a track frame, locking bolts, and a mounting plate. The track frame is fitted inside the track groove of the connecting frame, and a mounting plate is fixed to one end of the track frame. The hinge seat of the guide plate assembly is hinged to the connecting frame. One end of the hydraulic cylinder is hinged to the connecting frame via a pin, and the other end of the hydraulic cylinder is hinged to the guide plate assembly via a pin. Tension springs are hung on the pins at both ends of the hydraulic cylinder. The locking bolts lock the connecting frame to the track frame via the threaded seat of the connecting frame.
[0005] The fertilizer spreading width limiter for a fertilizer spreader described above has multiple guide plates at different angles on the guide plate assembly.
[0006] The beneficial effects of this utility model are: this utility model can make fertilizer move along the direction of the guide plate, thereby achieving the purpose of limiting the angle and width of fertilizer application. Attached Figure Description

Detailed Implementation
[0013] Referring to Figures 1 to 5, the technical solution of this utility model is implemented as follows: A fertilizer spreading width limiter for a fertilizer spreader includes a guide plate assembly 1, a pin 2, a tension spring 3, a hydraulic cylinder 4, a connecting frame 5, a track frame 6, a locking bolt 7, and a mounting plate 8. The track frame 6 is fitted inside the track groove 51 of the connecting frame 5. The mounting plate 8 is fixed to one end of the track frame 6. The hinge seat 9 of the guide plate assembly 1 is hinged to the connecting frame 5. One end of the hydraulic cylinder 4 is hinged to the connecting frame 5 through the pin 2, and the other end of the hydraulic cylinder 4 is hinged to the guide plate assembly 1 through the pin 2. Tension springs 3 are hung on the pins 2 at both ends of the hydraulic cylinder 4. The locking bolt 7 locks the connecting frame 5 to the track frame 6 through the threaded seat 52 of the connecting frame 5.
[0014] The fertilizer spreading width limiter of the above-mentioned fertilizer spreader has multiple guide plates 11 with different angles on the guide plate assembly 1.
[0015] When in use, this utility model is fixed near the spreading disc on the side and rear of the fertilizer spreader. When the oil cylinder extends, the guide plate assembly can be in a limited state. The fertilizer thrown out by the spreading disc changes its running trajectory under the limiting action of the guide plate. The fertilizer is thrown out along the direction of the guide plate, thus achieving the purpose of limiting the spreading angle and width of the fertilizer.
