Description

Technical Field

[0001] The utility model relates to the technical field of fertilization, and in particular to a device for accurately reducing the amount of chemical fertilizer applied. Background Art

[0002] Fertilization is the process of applying fertilizer to the soil to improve soil fertility. Before planting crops, it is generally necessary to apply appropriate amounts of fertilizer to the soil in the field to increase crop yields.

[0003] After searching, it was found that the Chinese utility model patent with authorization announcement number CN221104059U discloses a device for precise fertilizer reduction, which pours fertilizer into the feed trough, starts the second motor to make the auger transport the fertilizer to the storage box, starts the first motor to drive the connecting block to push the baffle, so that the baffle rotates, so that the fertilizer falls from the opening to the ground for fertilization, and the fertilizer can be accurately controlled without affecting the growth of crops, thereby improving the fertilization efficiency. However, there are some shortcomings: on the one hand, the baffle rotates , control the opening or closing of the opening to achieve fertilizer sprinkling. In this process, there are many factors that affect the fertilizer sprinkling. For example, the fertilizer is damp and lumpy and is not easy to fall off. During the movement of the trolley, the larger shaking amplitude will cause the fertilizer to fall down faster. Therefore, it is difficult to achieve the purpose of accurately controlling the amount of fertilizer sprinkling by simply relying on the method of controlling the opening or closing. This needs to be improved. On the other hand, it simply sprinkles the fertilizer on the soil surface. As we all know, when fertilizing before planting crops to improve soil fertility, it is best to bury the fertilizer in the soil. This needs to be improved.

[0027] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0028] Reference Figure 1-Figure 6 A device for accurately reducing the amount of fertilizer applied includes a frame 1. It should be noted that in this solution, the frame 1 only shows the chassis, and the remaining structures of the frame 1, such as wheels, handrails, etc., are not shown. They can be realized by existing technologies and will not be described in detail.

[0029] Reference Figure 1-Figure 3 A hopper 3 is installed on the frame 1 through a bracket 2, and a material pipe 4 is arranged at the bottom of the hopper 3. Furthermore, the axial centerline direction of the material pipe 4 is parallel to the vehicle width direction of the frame 1, and a material receiving nozzle 401 extends upward from the highest point of the outer cylindrical surface of the material pipe 4, and the material receiving nozzle 401 is connected to the bottom of the hopper 3.

[0030] An auger 5 is coaxially installed in the material pipe 4. The blades of the auger 5 are divided into two sections with opposite spiral directions along the axial direction and the connection between the two sections of the blades is located directly below the material receiving nozzle 401. A motor 6 for driving the auger 5 to rotate is provided at the end of the material pipe 4.

[0031] A discharge nozzle 7 extends downward from the lowest point of the outer circumferential surface of the material pipe 4 , and two discharge nozzles 7 are provided and are respectively close to the two ends of the material pipe 4 .

[0032] The fertilizer in the hopper 3 falls into the material pipe 4 through the receiving nozzle 401. At the same time, the motor 2 6 drives the auger 5 to rotate. The rotating auger 5 pulls the fertilizer to be transported to the two discharge nozzles 7 respectively, and finally falls downward through the discharge nozzles 7.

[0033] In the preferred embodiment, in order to make the fertilizer in the hopper 3 fall into the feed pipe 4 smoothly, refer to Figure 2 A support is provided at the upper end of the hopper 3, and a motor 301 is provided on the support. A stirring member 302 extending into the hopper 3 is provided at the output end of the motor 301. The stirring member 302 is driven by the motor 301 to stir the fertilizer in the hopper 3, so that the fertilizer can fall into the material pipe 4 smoothly. Further, the stirring member 302 includes a stirring shaft that is coaxial with the hopper 3 and connected to the power of the motor 301. A stirring rod extends from the outer cylindrical surface of the stirring shaft. It should be noted that since the hopper 3 has a truncated cone-shaped part, the length of the stirring rod needs to be adaptively changed, such as Figure 2 As shown.

[0034] Reference Figure 3-Figure 5 Two groups of digging parts are arranged at the bottom of the frame 1, and the two groups of digging parts are respectively located below the discharge nozzle 7. Furthermore, the digging parts include a shovel plate 9 and a covering plate 10, wherein the shovel plate 9 is located in front of the covering plate 10 along the forward direction of the frame 1, and the shovel plate 9 is composed of two inclined plates arranged obliquely, and the distance between the bottoms of the two inclined plates decreases along the forward direction of the frame 1, and the distance between the sides of the two inclined plates decreases from bottom to top along the vertical direction. In addition, a connecting rod extends vertically upward from the upper surface of the shovel plate 9, and the connecting rod is connected to a hydraulic rod 8 arranged on the frame 1, and the shovel plate 9 can be driven by the hydraulic rod 8. The height changes, and the shovel board 9 is used to dig a ditch in the field when the frame 1 moves forward. The end of the discharge nozzle 7 is located between the shovel board 9 and the covering plate 10, so that the fertilizer can fall into the ditch. It should be noted that, at the beginning, the shovel board 9 can be directly pressed into the soil by the hydraulic rod 8, or a pit can be dug in the field in advance, and the shovel board 9 can be placed in the pit. Then, when the shovel board 9 moves with the frame 1, a ditch can be dug. It should be noted that when the shovel board 9 digs the ditch, the soil generated is pushed to both sides of the ditch, so it can be filled back into the ditch by the subsequent covering plate 10.

[0035] The covering plate 10 is also composed of two inclined side plates. The distance between the two side plates increases along the forward direction of the frame 1. The maximum distance between the two side plates is greater than the maximum distance between the two inclined plates. After the fertilizer falls into the ditch, the covering plate 10 will gather the soil on both sides of the ditch and cover it into the ditch, thereby burying the fertilizer in the soil and achieving a better fertilization effect.

[0036] Preferred embodiment, refer to Figure 6The discharge nozzle 7 is in a trapezoidal shape with a horizontal cross-sectional area decreasing from bottom to top. A partition 701 is arranged between the two inner walls of the discharge nozzle 7 along the width direction. The upper and lower ends of the partition 701 are respectively located in the upper and lower openings of the discharge nozzle 7. A plurality of partitions 701 are arranged along the length direction of the discharge nozzle 7. The distance between the upper ends of two adjacent partitions 701 is equal, and the distance between the lower ends of two adjacent partitions 701 is equal. The significance of this is that, through the cooperation of a plurality of partitions 701, the fertilizer falling into the discharge nozzle 7 can be divided into several portions and sprinkled in the ditch, so as to achieve the purpose of evenly sprinkling the fertilizer into the ditch.
