[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0015] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.
[0016] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.
[0017] Combination Figure 1-3As shown, the manual quantitative fertilizer applicator includes a base 1, a push rod 2 is inserted into the base 1, a fertilizer box 3 is provided on the base 1, a discharging wheel 4 is rotatably provided in the fertilizer box 3 and located at the outlet position, a notch 5 is opened on the discharging wheel 4, a baffle 21 is provided on the inner side of the bottom of the fertilizer box 3 facing the discharging wheel 4, a discharge rack 6 is provided below the base 1 facing the outlet of the fertilizer box 3, a fertilizing mechanism for driving the discharging wheel 4 to rotate is provided on the push rod 2, the fertilizing mechanism includes a fixed sleeve 7 installed on the push rod 2, a linkage rod 8 is provided on the fixed sleeve 7, an intermediate block 9 is provided at the bottom of the linkage rod 8, the end of the intermediate block 9 is connected to the shaft 19 of the discharging wheel 4, and a spring 10 is provided between the fixed sleeve 7 and the base 1.
[0018] In the process of crop planting and management, topdressing is an important operation process. Timely topdressing plays a vital role in the growth of crops and is directly related to the yield of crops. In the process of crop planting and management, this topdressing device can be used to perform topdressing operations on crops to ensure the healthy growth of crops.
[0019] In this fertilizer applicator, the top of the push rod 2 is provided with a handle 11, and the bottom is a conical soil drilling head (blocked in the figure). When fertilizing crops, first place the base on the soil near the root of the crop as required, then hold the handle and push the push rod downward, the push rod moves downward in the base, and the soil drilling head drills into the soil until the spring is compressed. At this time, the soil forms a small fertilizer pit under the action of the soil drilling head. During the downward movement of the push rod, the fixed sleeve drives the linkage rod to move downward synchronously. Driven by the middle block, the discharging wheel rotates half a circle counterclockwise, and the fertilizer in its notch falls into the discharging rack and then falls into the fertilizer pit. At this time, the fertilization action is completed once, and the push rod can be pushed back and forth according to the fertilizer application amount requirements to complete the fertilization of crops.
[0020] When the push rod is lifted after fertilization is completed, the spring recovers its deformation, and the push rod and the discharge wheel are reset under the action of the spring, and the notch on the discharge wheel is located in the fertilizer box, and the fertilizer in the fertilizer box fills the notch again. By opening the notch on the discharge wheel, it is ensured that the amount of fertilizer applied to the crops is roughly the same each time, thereby achieving the effect of quantitative fertilization. Avoid the problem of excessive or insufficient fertilizer application, which leads to the growth of unutilized crops.
[0021] In this structure, the baffle plate acts as a material stopper to prevent fertilizer from flowing out directly from the gap between the fertilizer box and the discharge wheel. Meanwhile, during the fertilization process, the discharge wheel rotates toward the baffle plate, and the baffle plate smoothes the fertilizer in the slot.
[0022] As a preferred structure, Figure 2The fixing sleeve 7 and the base 1 are respectively provided with upper and lower short blocks 13, a guide screw 14 is inserted through the bottom of the lower short block, and a nut 20 is screwed into the end of the guide screw 14 after passing through the upper short block.
[0023] When the push rod is pushed downward, the fixed sleeve moves downward synchronously. In this process, the upper short block moves downward along the guide screw. Under the guidance of the guide screw, the push rod is more stable during the up and down movement. In addition, the guide screw also limits the distance of the push rod moving up and down.
[0024] Further as a preferred structure, Figure 2-3 The base 1 includes a sleeve 15, a circle of connecting blocks 16 are provided downward at the bottom of the sleeve 15, a bottom plate 17 is provided at the bottom of the connecting blocks 16, a circular opening 18 is opened at the axial position of the bottom plate 17, and the bottom of the unloading rack 6 is located in the circular opening.
[0025] In this structure, the sleeve is used as a carrier for installing the fertilizer box and the push rod. When fertilizing, the bottom plate contacts the soil and plays a role in supporting the fertilizer applicator. When fertilizing, a fixed amount of fertilizer falls from the lower material rack and falls into the fertilizer pit through the circular opening.
[0026] In addition, the fertilizer box 3 is a structure that is wide at the top and narrow at the bottom, and a box door (not shown) is rotatably provided on the top of the fertilizer box 3. Before fertilizing the crops, the corresponding fertilizer is first loaded into the fertilizer box, and then the box door is closed. The fertilizer box is a structure that is wide at the top and narrow at the bottom, which can reduce the volume of the fertilizer box on the one hand, and facilitate the dropping of fertilizer in the fertilizer box on the other hand.
[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
