Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural science and technology, and more specifically, particularly relates to a fertilizing device for crops. Background Art

[0002] Agriculture and animal husbandry refers to agriculture and animal husbandry. Animal husbandry mainly includes the breeding of cattle, horses, donkeys and other livestock and poultry, and the domestication of deer, minks and other wild economic animals. It not only provides raw materials for industries such as textiles, oils, food, and pharmaceuticals, but also provides rich food such as meat, milk, eggs, and poultry for people's lives, and provides draft animals and manure for agriculture.

[0003] Based on the above, the inventors have found the following problems: In agriculture, crops need to be fertilized to ensure their growth. At present, there are many fertilizer vehicles that can improve the efficiency of fertilization. When the fertilizer vehicle is in use, the fertilizer is poured into the material box and then gradually fertilized through the fertilizer port. However, after the bagged fertilizer is produced and bagged, the fertilizer is easy to agglomerate. After being poured into the material box, there is no screening device, and the agglomerated fertilizer is easy to block the fertilizer port, so that the fertilization equipment needs to be opened for adjustment, which reduces the overall fertilization efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a fertilization device for crops is provided, in order to achieve the purpose of having more practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a fertilizing device for crops, so as to solve the problem that the existing fertilizing device has no screening device and the lumped fertilizer easily blocks the fertilizing port.

[0007] A fertilization device for crops comprises a fertilization vehicle, wherein the fertilization vehicle is provided with a fertilizer box, a fixed frame is installed on the fertilizer box, a screening box is movably provided inside the fixed frame, sieve holes are provided on the screening box, connecting pieces are installed at both ends of the screening box, a connecting shaft is installed inside the connecting piece, the connecting piece is connected to a driving wheel via the connecting shaft, rotating rods are installed at both ends of the screening box inside the fixed frame, a cam is installed in the middle of the rotating rod, and the position of the cam corresponds to the position of the driving wheel.

[0008] Furthermore, the number of the cams and the driving wheels is two, the two driving wheels are respectively located at the two ends of the screening box, the two cams are arranged in the same direction, and the two cams can alternately drive the two driving wheels.

[0009] Furthermore, a limiting wheel is installed at the lower part of the screening box, support plates are installed at both sides of the interior of the fixed frame, the support plates are provided with limiting grooves, and the limiting wheels are located inside the limiting grooves.

[0010] Furthermore, a cover plate is connected to one side of the fixed frame via a hinge, a pressing plate is mounted on the cover plate, the size of the pressing plate matches the inner size of the screening box, and the pressing plate can enter the interior of the screening box.

[0011] Furthermore, there are two rotating rods, and one end of each rotating rod passes through the side surface of the fixed frame. A passive bevel gear is installed at one end of each rotating rod, and the side surface of the passive bevel gear is meshedly connected with the active bevel gear.

[0012] Furthermore, the number of the active bevel gears is two, which are connected by a rotating shaft, a dual-axis motor is installed in the middle of the rotating shaft, the output end of the dual-axis motor is transmission-connected to the rotating shaft, and the dual-axis motor is connected to a fixed frame.

[0013] Furthermore, the fertilizer vehicle is provided with rollers, and the lower part of the fertilizer box is provided with a fertilizer port.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the utility model, the active bevel gear drives the passive bevel gear meshing with the active bevel gear to rotate, and the two passive gears drive the rotating rods to rotate synchronously. When the two rotating rods rotate, the cams can be driven to rotate. The cams located in the screening box rotate continuously, and the driving wheels at both ends can be alternately driven to make the screening box reciprocate. Through the reciprocating motion of the screening box, the fertilizer inside can pass through the sieve holes and enter the interior of the fertilizer box at the lower part.

[0016] In the utility model, when there are many agglomerated fertilizers in the screening box, the dual-axis motor stops and the cover is closed. At this time, the pressing plate enters the interior of the screening box and applies force to the cover to crush the agglomerated fertilizers. Manual crushing is unnecessary, thereby improving the overall practicality. BRIEF DESCRIPTION OF THE DRAWINGS
