Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, and more particularly to a fertilizer spreader. Background Art

[0002] A fertilizer spreader is a piece of mechanical equipment used in agriculture and horticulture to apply fertilizer evenly to the rhizosphere of plants. It can release the right amount of fertilizer into the soil during tillage or planting to meet the nutrient needs of plants and promote their healthy growth. By using a fertilizer spreader, farmers and gardening enthusiasts can apply fertilizer more conveniently and efficiently, thereby improving crop yield and quality.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0023] A fertilizer spreading machine Figure 1 and Figure 2As shown, it includes a feeding assembly 1 and a storage box 2 above the feeding assembly 1. The storage box 2 is conical in shape, and a screen 3 is rotatably connected to the storage box 2. The screen 3 is circular. By arranging a rotating screen 3 in the storage box 2, it is convenient to block the agglomerated fertilizer. A fixing ring 4 for supporting the screen 3 is welded on the inner wall of the storage box 2. A fixing ring 4 is arranged on the inner wall of the storage box 2, which supports the screen 3. The screen 3 is inclined, so that when the screen 3 rotates, the fertilizer will move driven by the screen 3, so that normal fertilizer can pass through the screen 3. The screen 3 is fixedly connected to one end of the feeding assembly 1 with a driving assembly for driving the screen 3 to rotate. The screen 3 is arranged with a driving assembly towards one end of the feeding assembly 1 to realize the rotation of the screen 3.

[0024] like Figure 2 and Figure 5 As shown, the driving assembly includes a connecting rod 6 and a handle 7. One end of the connecting rod 6 is welded to the center of the screen 3, and the connecting rod 6 is perpendicular to the screen 3. A rotating hole 8 passed by the connecting rod 6 is opened on the storage box 2, and the other end of the connecting rod 6 extends out of the storage box 2 and is welded to the handle 7. By arranging the connecting rod 6 and the handle 7, one end of the connecting rod 6 is fixedly connected to the center of the screen 3, and a rotating hole 8 passed by the connecting rod 6 is opened on the storage box 2, and the other end of the connecting rod 6 extends out of the storage box 2 and is fixedly connected to the handle 7. Rotating the handle 7 drives the rotation of the connecting rod 6, and then drives the rotation of the screen 3. A bearing 9 is provided in the rotating hole 8, and the outer ring of the bearing 9 is fixedly connected to the storage box 2, and the inner ring of the bearing 9 is fixedly connected to the connecting rod 6. By arranging a bearing 9 in the rotating hole 8, the outer ring of the bearing 9 is fixedly connected to the storage box 2, and the inner ring of the bearing 9 is fixedly connected to the connecting rod 6, so as to facilitate the rotation of the connecting rod 6 in the rotating hole 8.

[0025] like Figure 2 and Figure 4 As shown, a grinding sheet 10 is rotatably connected to the inner wall of the storage box 2. By arranging a rotating grinding sheet 10 on the inner wall of the storage box 2, when the grinding sheet 10 is parallel to the screen 3, the agglomerated fertilizer will be squeezed by the grinding sheet 10 while the screen 3 rotates, so that the agglomerated fertilizer is crushed, and when encountering large pieces of fertilizer, the grinding sheet 10 can be rotated and squeezed to squeeze the fertilizer, thereby further improving the crushing effect. A bolt hole 11 is opened on the grinding sheet 10, and a bolt hole 11 is opened on the storage box 2. A corresponding through hole 12 is set, and the through hole 12 contains a bolt 13 for threaded fixation with the bolt hole 11. When the grinding sheet 10 is parallel to the screen 3, the bolt 13 can enter the bolt hole 11 to fix the grinding sheet 10. By opening a bolt hole 11 on the grinding sheet 10, and opening a through hole 12 corresponding to the position of the bolt hole 11 on the storage box 2, the through hole 12 contains a bolt 13 for threaded fixation with the bolt hole 11, and the bolt 13 passes through the through hole 12 and enters the threaded hole, thereby fixing the grinding sheet 10.

[0026] like Figure 2 and Figure 3 As shown, a ring groove 5 is provided on the fixing ring 4, and the edge of the screen 3 is rotatably connected in the ring groove 5. By providing the ring groove 5 on the fixing ring 4, the edge of the screen 3 rotates in the ring groove 5, thereby achieving support of the screen 3 by the fixing ring 4. A stirring piece 14 is welded on the screen 3. The width of the stirring piece 14 is equal to the distance between the grinding piece 10 and the screen 3 when the grinding piece 10 is parallel to the screen 3. By arranging the stirring piece 14 on the screen 3, the filtering effect of the screen 3 is improved. The stirring piece 14 is perpendicular to the screen 3. By arranging the stirring piece 14 to be perpendicular to the screen 3, the stirring piece 14 can conflict with the grinding piece 10, so that the stirring piece 14 and the grinding piece 10 can provide shear force to the agglomerated fertilizer, thereby improving the crushing effect of the agglomerated fertilizer.

[0027] Working process: When screening the fertilizer, the operator first puts the fertilizer into the storage box 2. At this time, the fertilizer is above the screen 3. Then the operator holds the handle 7 and rotates it at the same time. During this process, the connecting rod 6 also rotates under the drive of the handle 7. At this time, the connecting rod 6 rotates in the rotating hole 8. Since a bearing 9 is provided in the rotating hole 8, the inner ring of the bearing 9 is fixedly connected to the connecting rod 6, so that the bearing 9 rotates. At the same time, the screen 3 also rotates under the rotation of the connecting rod 6. Since the rotating plane of the screen 3 has an angle with the opening of the storage box 2, and the screen 3 is fixedly connected with a stirring piece 14, the stirring piece 14 stirs the fertilizer when the screen 3 rotates, thereby facilitating the screening of the corresponding fertilizer.

[0028] When crushing the agglomerated fertilizer, the operator rotates the grinding plate 10. When the grinding plate 10 is parallel to the screen 3, the operator rotates the bolt 13. During this process, the bolt 13 enters the bolt hole 11 on the grinding plate 10, thereby fixing the grinding plate 10. At this time, the operator continues to rotate the handle 7, and the screen 3 and the stirring plate 14 on the screen 3 rotate. When rotating, the stirring plate 14 presses the agglomerated fertilizer directly into the grinding plate 10 and the screen 3, thereby achieving a crushing effect, so that the crushed fertilizer can pass through the screen 3. When encountering fertilizer with a large agglomerate volume and a hard agglomerate hardening degree, the operator can turn out the bolt 13, and at the same time the operator can rotate the grinding plate 10 to squeeze and crush the fertilizer.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
