Description

Technical Field

[0001] The invention relates to the technical field of fertilization, in particular to a fertilization device for agricultural planting. Background Art

[0002] With the continuous development of modern agricultural mechanization, most crops such as sowing and harvesting have corresponding mechanized equipment to replace manual labor. However, there are few modern large-scale mechanical equipment to complete the intermediate process of fertilizing crops in the field. In addition, large-scale machinery has certain requirements for the geographical environment of crop cultivation, crop types and planting spacing. Especially for small fields or fields with trees and other crops, as well as uneven fields or fields with ditches such as mountains, large-scale machinery cannot be used for operation due to geographical restrictions, and it will cause damage to crops. Therefore, the use of hand-held fertilization is the best choice for areas restricted by geography and small-area planting.

The second pressing rod 53 is extended by the rotation of the connecting disk 52, thereby increasing the frequency of pressing the sliding rod 8 downward.

[0042] See also Figure 5-6 The limiting component 55 includes a rotating handle 551, which is arranged on the second cross bar 521, and a limiting block 554 is arranged on the sleeve 54.

[0043] See also Figure 3 and Fig. 9The linkage mechanism 7 includes a sliding plate 73, which slides on the side plate 32. An avoidance groove 731 is opened on the sliding plate 73, and the sliding rod 8 passes through the avoidance groove 731. A mounting seat 61 is provided on the side plate 32, and a cross bar three 62 is rotatably provided on the mounting seat 61.

During the folding and rotation of the guide pipe 6, the cross bar three 62 rotates along with it, and the winding wheel 71 rotates synchronously with the cross bar three 62, so that the steel wire rope 72 winds up the steel wire rope 72 and causes the sliding plate 73 to move. Through the avoidance groove 731, the sliding rod 8 can be displaced on the sliding plate 73. At the same time, when the sliding plate 73 moves down, the sliding plate 73 can also pull the sliding rod 8.

[0044] See also Figure 2 A cross bar 21 is provided on the front wheel 2, and the cross bar 21 is provided on both sides of the fertilizer spreader body 1. The front wheel 2 is connected to the fertilizer spreader body 1 through the cross bar 21.

[0045] See also Fig.10 A material distribution box 10 is arranged between the side plates 32, and the material distribution box 10 is arranged below the movable plate 91. A partition plate 101 is arranged inside the material distribution box 10. A separation port 102 is arranged at the lower end of the material distribution box 10. The separation port 102 is in contact with the material guide pipe 6, and the material guide pipe 6 is movably connected with the separation port 102. When the fertilizer in the storage hopper 3 falls into the material distribution box 10, the material is diverted from the separation port 102 and falls into the corresponding material guide pipe 6 through the partition plate 101.

[0046] See also Fig.11 A cross bar 121 is provided on the fertilizer spreader body 1, and the rear wheels 12 are provided at both ends of the cross bar 121, and the rear wheels 12 are connected to the fertilizer spreader body 1 through the cross bar 121.

[0047] See also Fig.12 A mounting plate 112 is provided on the fertilizer spreader body 1, a vertical rod 113 is rotatably provided on the mounting plate 112, a connecting gear 114 is provided on the vertical rod 113, the upper end of the vertical rod 113 is connected to the spreading disc 11, the spreading disc 11 is arranged below the separation port 102, an end gear 115 is provided on the cross bar 121, the end gear 115 is engaged with the connecting gear 114, and a limiting plate 111 is provided on the fertilizer spreader body 1, the limiting plate 111 is arranged on both sides of the spreading disc 11, and the limiting plate 111 is opened on both sides so that the fertilizer can be sprinkled on both sides through the opening.

[0048] When in use, the front wheel 2 and the rear wheel 12 are rolled by pushing the fertilizer spreader body 1. When the front wheel 2 rolls, the sleeve 54 is rotated through the chain 4, and the rotating disk 51 is driven to rotate. When the first pressing rod 511 contacts the sliding rod 8, the sliding rod 8 is pushed downward. Since the sliding rod 8 is embedded in the inclined groove 921, when the sliding rod 8 moves downward, the moving plate 91 moves and squeezes the spring 2 93 until the connecting port 911 is aligned with the discharge port 33, so that the fertilizer in the storage hopper 3 falls into the distribution box 10, and the material is divided and falls from the separation port 102 to the guide pipe 6 through the partition plate 101, and falls to the ground at intervals through the guide pipe 6, so as to perform spot application on the plants.

[0049] The connecting plate 52 on the second crossbar 521 of the sleeve 54 is rotated by rotating the rotating handle 551, and the second pressing rod 53 is extended until the second pressing rod 53 is extended to a length that can contact the sliding rod 8. At this time, the limiting rod 552 is embedded in another hole on the limiting block 554, so that the rotating handle 551 has a certain fixing effect, thereby increasing the moving frequency of the sliding rod 8 through the first pressing rod 511 and the second pressing rod 53, thereby shortening the distance of fertilizer point application;

[0050] By folding the guide tube 6 and fixing it with the buckle 31, during the folding and rotating process of the guide tube 6, the cross bar 3 62 rotates, and the winding wheel 71 rotates synchronously with the cross bar 3 62, so that the wire rope 72 winds up the wire rope 72, and the sliding plate 73 is displaced, and the sliding rod 8 is pulled at the same time, so that the sliding rod 8 moves downward. When the guide tube 6 is fixed with the buckle 31, the position of the sliding rod 8 is fixed at the same time, so that the connection port 911 and the discharge port 3 3 is always in a connected state. Since the guide tube 6 is in a folded state, the fertilizer directly falls onto the spreading plate 11 through the material distribution box 10. When the rear wheel 12 rotates, the end gear 115 on the cross bar 121 rotates synchronously, and the end gear 115 drives the connecting gear 114 to rotate, thereby rotating the spreading plate 11. When the fertilizer falls onto the spreading plate 11, the fertilizer is scattered by centrifugal action, so that the fertilizer spreader body 1 can be switched to the spreading mode.
