Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a fertilizer applicator. Background Technology
[0002] Fertilizer applicators are typically installed at the bottom of the tractor and connected to the fertilizer tank, used to apply fertilizer from the tank. Currently, fertilizer applicators mainly consist of a plow body, a furrowing shovel, and a fertilizer application tube. The plow body is detachably connected to the tractor; the furrowing shovel is detachably connected to the bottom of the plow body and extends forward in the direction of travel; the fertilizer application tube is fixed at the rear end of the plow body in the direction of travel, and its top end is connected to the fertilizer tank, allowing fertilizer application to be performed while the plow body and fertilizer application tube are in motion.
[0003] However, in actual fertilization, due to the different sizes of the plow body and the fertilizer pipe, there is a groove at the connection between the plow body and the fertilizer pipe. Soil is very easy to stick to the groove between the plow body and the fertilizer pipe, which greatly increases the travel resistance of the tractor. At the same time, the trenching shovel is small in size and is very easy to deform and be damaged, so it cannot be used for a long time. In addition, the lower front part of the plow body is in direct contact with the soil, which is very easy to break, affecting the service life of the plow body.
[0004] Therefore, how to design a fertilizer applicator that is not easily stuck to the soil, is not easily deformed or damaged, and has a long service life is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] This utility model provides a fertilizer applicator that solves the technical problems of existing fertilizer applicators, such as easy adhesion to soil, increased driving resistance, easy damage, and short service life.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a fertilizer applicator, comprising: a plow body, a fertilizer pipe, a soil-breaking component, and a trenching shovel.
[0007] The plow body is detachably connected to the tractor and has a fixed groove at the upper rear end in the direction of travel, and a fertilizer trough at the lower rear end in the direction of travel. The fixed groove has a fertilizer hole communicating with the fertilizer trough. The bottom end of the fertilizer pipe is inserted into the fixed groove and communicates with the fertilizer hole. The soil breaking component is detachably connected to the front end in the direction of travel of the plow body. The trenching shovel includes an integrally connected fixed part and a shovel head. The fixed part is detachably connected to the bottom end of the plow body. The shovel head is located in front of the plow body in the direction of travel.
[0008] The beneficial effects of this utility model are: it improves the structure of the traditional fertilizer spreader. First, a fixing groove is opened at the rear end of the plow body in the direction of travel, and then one end of the fertilizer spreading tube is inserted into the fixing groove. This can prevent soil from sticking to the connecting groove between the fertilizer spreading tube and the plow body, prevent the plow body from sticking to the soil, and increase the travel resistance of the tractor.
[0009] Based on the above technical solution, the present invention can be further improved as follows.
[0010] Furthermore, the plow body includes an integrally connected upper plow body section and a lower plow body section, the upper plow body section being detachably connected to the tractor; the lower plow body section is arranged at an obtuse angle α with the upper plow body section and extends to the front of the upper plow body section in the direction of travel; the fixing groove is located at the upper rear end of the lower plow body section in the direction of travel; the fertilizer trough is located at the lower rear end of the lower plow body section in the direction of travel.
[0011] Furthermore, the obtuse angle α is 120–160°.
[0012] Furthermore, the two opposite sides of the fixed groove are provided with insertion grooves, the fertilizer dispensing hole is located at the bottom of the insertion groove, and the bottom end of the fertilizer tube passes through the fixed groove and extends into the insertion groove.
[0013] Furthermore, the cross-section of the soil-breaking component is a triangular structure, and its large-area end is detachably connected to the front end of the plow body in the direction of travel.
[0014] The further beneficial effect of adopting the above is that the cross-section of the soil-breaking component is designed as a triangular structure and its large-area end can be detachably connected to the front end of the plow body in the direction of travel. This can effectively break the soil and also effectively protect the plow body, thus extending the service life of the plow body.
[0015] Furthermore, it also includes a fertilizer guide plate, which is fixed on the opposite two sides of the fertilizer trough and is arranged downwards sequentially from the front end of the plow body in the direction of travel to the rear end of the plow body in the direction of travel. The fertilizer guide plate is arranged opposite to the fertilizer hole.
[0016] The further beneficial effect of adopting the above is that by using the inclined fertilizer guide plates fixed on the opposite two sides of the fertilizer drop trough, the falling direction of fertilizer particles can be effectively guided, and the spreading range of fertilizer particles can be standardized.
[0017] Furthermore, the fertilizer guide plates are multiple plates arranged along the height direction of the plow body.
[0018] The further beneficial effect of adopting the above is that by designing multiple seed guide plates arranged along the height of the plow body, layered fertilization can be achieved.
[0019] Furthermore, both the plow body and the fertilizer pipe are made of metal.
[0020] Furthermore, both the soil-breaking component and the trenching shovel are made of alloy materials. Attached Figure Description
