Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural equipment and relates to a handle structure of a handheld fertilizer applicator. Background Art

[0002] In the process of planting crops, it is necessary to apply fertilizer to the soil to provide the plants with the necessary nutrients, thereby increasing the yield of crops and maintaining and improving the fertility of the soil. The original method of fertilization was done by hand, which would lead to uneven fertilization and seedling burning. In order to improve the method of fertilization, many fertilization equipment have been invented, including a hand-pushed roller fertilizer applicator that can bury fertilizer in the soil, but this fertilizer applicator is large in size and very laborious to push. In the prior art, there is a fertilization method in which solid fertilizer particles are added to a small handheld fertilizer spreader, and a storage box is carried on the back and is higher than the feed inlet of the fertilizer spreader, so that the fertilizer enters the fertilizer spreader from the feed inlet under the influence of gravity, and then the fertilizer is spread into the soil by internal rotation and centrifugal force. This fertilizer spreader can evenly spread the fertilizer on the soil, but the handle structure of the existing handheld fertilizer spreader is simple, and fertilizer can only be applied by holding it with one hand. Long-term fertilization will make the wrist uncomfortable, and the height of the fertilizer spreader cannot be adjusted, and the height of the fertilizer spreader needs to be lowered by bending over.

[0003] Therefore, the handheld fertilizer spreader in the prior art still has some shortcomings during use: 1. The handle structure of the fertilizer spreader is single and cannot support more ways of holding; 2. When operating the fertilizer spreader with one hand to fertilize, the hand is prone to fatigue. 3. Fertilizing short crops requires bending over, which will cause waist pain. Summary of the invention

[0004] The purpose of the utility model is to propose a handheld fertilizer applicator in view of the problems existing in the prior art. The technical problem to be solved by the utility model is: how to improve the comfort of manual use of the fertilizer applicator.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a handheld fertilizer applicator, comprising a fertilizer applicator body and a rotating handle provided with a gripping portion, the fertilizer applicator body being provided with a supporting portion, one end of the rotating handle being provided with a hinged portion hingedly connected to the supporting portion, characterized in that a card slot is provided on the supporting portion, the hinged portion is located on one side of the card slot, a reciprocating slider is provided on the hinged portion, one end of the slider cooperates with the card slot so that the rotating handle is card-connected to the fertilizer applicator body.

[0006] In the present scheme, the support part is located at the top of the fertilizer applicator body, and the hinged part where the rotating handle with the grip part is hingedly connected to the support part is the rotating point. The rotating handle can rotate around the hinged part. After rotation, the end of the handle away from the hinged part is used for grasping. A slider is provided on the rotating handle, and the slider is located at one end close to the hinged part of the rotating handle. The slider can move back and forth under the action of external force. A card slot is provided on the support part. After the rotating handle is rotated and opened, the slider can be pushed into the card slot by sliding the slider by hand, thereby fixing the rotated handle. The fixed rotating handle is in a vertical state with the support part, and the high part of the rotating handle can be grasped. By fixing the rotating handle in the above manner, while facilitating the adjustment of the height of the fertilizer applicator body, fatigue caused by bending can be avoided, and the state can be fixed to improve the stability of the fertilizer applicator body, thereby improving the comfort of manual use of the handheld fertilizer applicator. Since it is limited to vertical and horizontal placement, it has a simple structure and relatively high stability.

[0007] In the above-mentioned handheld fertilizer spreader structure, the inner wall of the U-shaped support part fits with the rotating handle. Through the above-mentioned support part structure, the rotating handle can be stored in the U-shaped groove of the support part when not in use, saving storage space and protecting the rotating handle.

[0008] In the above-mentioned handheld fertilizer spreader structure, a slide groove is provided on the rotating handle, and the slide groove cooperates with the slider. Through the above-mentioned slide groove structure, the slider can be easily moved back and forth on the rotating handle.

[0009] In the above-mentioned handheld fertilizer spreader structure, a limit groove is provided at the bottom of the slide groove, and a sliding track is provided on the side of the slide groove. The limit groove is divided into two front and rear limit grooves, the front limit groove is used to limit the position of the slider after the slider is pushed into the slot, and the rear limit groove is used to limit the position of the slider when the rotating handle is not in use. The sliding track on the side of the slide groove provides a guide rail for the slider, fixes the path of the slider moving in the slide groove, and through the above-mentioned internal structure of the slide groove, the movement of the slider is limited, thereby improving the stability of the slider moving in the slide groove.

[0010] In the above-mentioned handheld fertilizer spreader structure, a limiting part is provided at the bottom of the slider, sliding parts are provided on both sides of the slider, the slider is slidably connected to the slide groove, and a clamping part is provided at one end of the slider.

The sliding part of the slider is installed in the sliding track of the slide groove. Through the above-mentioned slider structure, while the slider can move on the slide groove, it can also prevent the slider from falling off from the slide groove, so that the clamping block of the slider can cooperate with the clamping groove to fix the slider in the clamping groove.

[0011] In the above-mentioned handheld fertilizer spreader structure, the slider is provided with a pushing part, which is a protruding structure on the slider, and the slider can be pushed to move during use through the pushing part.

[0012] In the above-mentioned handheld fertilizer spreader structure, a partition is further provided between the clamping slot and the hinged portion. The partition can limit the rotation angle of the rotating handle, and through the restriction of the rotating handle by the partition, the clamping portion of the sliding block is rotated to be parallel to the clamping slot, which facilitates the insertion of the clamping portion into the clamping slot.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. In this solution, the rotating handle of the handheld fertilizer spreader can be adjusted in angle. The rotating handle is separated from the support part. Both the rotated handle and the support part can be grasped, so that two graspable parts are provided, making it more comfortable to use the fertilizer spreader with both hands.

[0015] 2. In this solution, after the rotating handle of the handheld fertilizer spreader is rotated, the upper rotating handle can be grasped by one hand to lower the height of the fertilizer spreader body, thereby avoiding fatigue caused by bending over when fertilizing short crops.

[0022] like Figure 1As shown, a U-shaped support portion 3 is provided on the fertilizer applicator body 1, and the support portion 3 is located at the top of the fertilizer applicator body 1, and the U-shaped opening faces upward. A card slot 3a is provided on the support portion 3, and a rotating handle 2 is matched with the support portion 3. The rotating handle 2 is in an L-shaped or T-shaped structure. A hinge portion 2b is provided on the rotating handle 2, which is hingedly connected to the support portion 3. The rotating handle 2 can rotate around the hinge portion 2b. A slide groove 2a is also provided on the rotating handle 2, and a slider 4 is installed inside the slide groove 2a. The slider 4 can reciprocate inside the slide groove 2a. After the rotating handle 2 is rotated, the slider 4 moves down The slider 4 is inserted into the slot 3a, and the slider 4 is fixed in the slot 3a, wherein the fertilizer applicator body 1 includes an upper shell 1a and a bottom shell 1b, the upper shell 1a includes a cover body 1a1 matched with the bottom shell 1b and a motor shell 1a2 hingedly connected to the rotating handle, one end of the motor shell 1a2 is integrally connected to the cover body 1a1, and the other end is connected to the rotating handle 2 through the support part 3, and a feed port 1a3 is integrally connected to the cover body 1a1, the feed port 1a3 is located on one side of the rotating handle 2, and is inclined relative to the cover body 1, and the bottom shell 1b cooperates with the cover body 1a1 to form a discharge port 1a4.

[0023] like Figure 2 Combination Figure 1 As shown, the rotating handle 2 is installed in the U-shaped supporting part 3 and is connected by the hinge part 2b. A pin is inserted in the hinge part 2b. A partition 3b is provided between the card slot 3a and the hinge part 2b. A limiting groove 2aa is provided at the bottom of the slide slot 2a of the rotating handle 2. A sliding track 2ab is provided on the side of the slide slot 2a. A limiting part 4b is provided at the bottom of the slider 4. The limiting part 4b cooperates with the limiting groove 2aa of the slide slot 2a to limit the slider 4. A sliding part is provided on the side of the slider 4. The sliding part and the sliding track 2ab are provided on the slider 4. The sliding part can move along the sliding track 2ab and prevent the slider 4 from falling off from the slide groove 2a. The slider 4 is provided with a clamping part 4c, which can be inserted into the clamping groove 3a. The slider 4 is also provided with a pushing part 4d, which is a protruding structure on the slider 4. A turntable 5 is provided between the cover 1a1 and the bottom shell 1b. The turntable 5 is connected to the driving machine 6 located in the motor housing 1a2, and a discharge port 1a4 is provided at the front end of the turntable 5.

[0024] The working principle of this scheme is as follows: Figure 2As shown, it is the initial state of the fertilizer applicator body 1 and the rotating handle 2 in this embodiment, the rotating handle 2 is placed in the U-shaped groove of the support part 3, the rotating handle 2 and the support part 3 are parallel and both are in a horizontal state, the slider 4 is installed in the slide groove 2a on the rotating handle 2, and the sliding part on the slider 4 is slidably connected with the sliding track 2ab of the slide groove 2a. Under the action of force, due to the limitation of the sliding track 2ab, the slider 4 can only slide along the sliding track 2ab of the slide groove 2a. At the same time, due to the limiting effect of the sliding track 2ab on the sliding part, the slider 4 will not fall off from the slide groove 2a. There are two limiting grooves 2aa at the bottom of the slide groove 2a, and the limiting part 4b at the bottom of the slider 4 cooperates with the limiting groove 2aa. When the slider 4 slides, the limiting part 4b of the slider 4 encounters the slide groove 2 The limiting groove 2aa of a will slide into the groove, and the limiting part 4b can leave the limiting groove 2aa only under the action of external force, so that the slider 4 will not move when the rotating handle 2 is rotated, and the slider 4 has a limiting function. The pushing part 4d of the slider 4 is to facilitate the external force to act on the slider 4 and push the slider 4 to move. During use, the fertilizer is allowed to enter from the feed port 1a3 by manual pouring, and while the driving machine 6 drives the turntable 5 to rotate, the fertilizer on the turntable 5 will be affected by the centrifugal motion and thrown out from the discharge port 1a4. As an alternative, it can also adopt a backpack type, by storing the fertilizer in a backpack, and connecting the feed port 1a3 to the backpack through a hose, wherein the end of the hose connected to the backpack is higher than the end of the hose connected to the feed port.

[0025] like Figure 3 When the fertilizer spreader is used for fertilizing, the rotating handle 2 is rotated along the hinged portion 2b under the action of external force. However, since there is a partition 3b between the hinged portion 2b and the slot 3a, the rotating handle 2 cannot continue to rotate after it is turned from horizontal to vertical. When the rotating handle 2 is perpendicular to the supporting portion 3, the clamping portion 4c of the slider 4 is parallel to the slot 3a. When the slider 4 is pushed by external force, the clamping portion 4c will be inserted into the slot 3a, so that the slider 4 is fixed above the slot 3a. The partition 3b limits the rotation angle of the rotating handle 2, allowing the clamping portion 4c to be parallel to the slot 3a, making it convenient for the clamping portion 4c to be inserted into the slot 3a. Since the slider 4 is fixed In the fixed card slot 3a, with the cooperation of the sliding part of the slider 4 and the sliding track 2ab of the slide slot 2a, the slider 4 cannot be separated from the slide slot 2a, so that the rotating handle 2 will remain perpendicular to the support part 3; the gripping part on the rotating handle 2 can be grasped by the gripping part and the support part 3 at the same time when using the fertilizer spreader, so that it can be grasped with both hands, which is more comfortable than holding it with one hand; after the rotating handle 2 is rotated, the gripping part is higher than the rotating handle 2 when it is not in use. When fertilizing low crops, the gripping part at a high position can be grasped, thereby lowering the height of the fertilizer spreader body 1 and making the discharge port closer to the crops, thereby avoiding fatigue caused by bending over.
