[0002] During the transplanting process of plant seedlings, watering the root - fixing water is a crucial step, which has a significant impact on the survival rate and subsequent growth of plant seedlings. The root - fixing water is usually applied immediately after transplanting the plant seedlings, aiming to promote the close contact between the root systems of the plant seedlings and the soil, enabling the root systems to absorb water and nutrients from the soil and promoting the rapid recovery of plant growth. In actual operation, if the amount of water applied is too small, it may lead to insufficient close contact between the soil and the root systems of the plant seedlings, affecting the survival rate of the plant seedlings. If the amount of water applied is too much, it may cause excessive soil humidity, affecting the root respiration of the plant seedlings and even triggering diseases. Therefore, reasonably controlling the amount of root - fixing water is decisive for ensuring the healthy growth of plant seedlings after transplantation.

[0003] In the existing transplanters, the amount of water discharged by the watering device is fixed and uncontrollable, and it is prone to situations of too much or too little water discharge in actual applications. Summary of the Invention

[0046] The following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0047] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0048] In the present utility model, unless otherwise stated, the orientation words such as "upper, lower, top, bottom" are usually in the direction shown in the drawings or in terms of the vertical, perpendicular or gravitational direction for describing the relative positional relationship of each component.

[0049] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0050] The present utility model first provides a watering device.

[0051] In one embodiment, referring to the attached Figure 1 to the attached Figure 4 as shown, the watering device includes:

[0052] Water storage tank 1;

[0053] Piston water pump 2, the water inlet is connected to the water storage tank 1, and the water outlet is connected to a watering pipe;

[0054] The driving arm 3 includes a driving arm body 31 and a connecting rod connecting member 32. The connecting rod connecting member 32 is detachably connected to the driving arm body 31, and the connection position is adjustable between the first end and the second end of the driving arm body 31. The driving arm body 31 is arranged to be rotatable around the first end;

[0055] The connecting rod mechanism has one end connected to the piston rod 21 of the piston type water pump 2 and the other end movably connected to the connecting rod connecting member 32;

[0056] Wherein, the rotation of the driving arm body 31 around the first end can drive the connecting rod mechanism to swing, so as to drive the piston rod 21 to make a reciprocating motion.

[0057] In the watering device of the embodiment, the driving arm body 31 is arranged to be rotatable around the first end. The rotation of the driving arm body 31 around the first end can drive the connecting rod mechanism to swing, so as to drive the piston rod 21 to make a reciprocating motion. Thus, in actual application, by driving the rotation of the driving arm body 31, the piston in the piston type water pump 2 can be driven to make a reciprocating motion through the connecting rod mechanism and the piston rod 21, so as to pump out the water in the water storage tank 1 and discharge the water through the watering pipe to realize watering; One end of the connecting rod mechanism is movably connected to the connecting rod connecting member 32. The connecting rod connecting member 32 is detachably connected to the driving arm body 31, and the connection position is adjustable between the first end and the second end of the driving arm body 31. Thus, by adjusting the connection position of the connecting rod connecting member 32, the connection position of one end of the connecting rod mechanism and the driving arm body 31 can be adjusted. By doing so, the swing amplitude of the connecting rod mechanism can be adjusted, and then the stroke of the piston of the piston type water pump 2 can be adjusted, and finally the watering amount of the watering device can be adjusted. In the process of actually applying it to water the root-fixing water, the watering amount can be adjusted according to the needs to avoid the situation of too much or too little watering amount.

[0058] Specifically, the driving arm 3 further includes a fastening member 33. The driving arm body 31 is provided with a limiting groove and a long hole. The limiting groove and the long hole respectively extend from the first end of the driving arm body 31 to the second end of the driving arm body 31 and communicate with each other. At least part of the connecting rod connecting member 32 is limited in the limiting groove and is provided with a connection hole corresponding to the long hole. The fastening member 33 is detachably inserted through the long hole and the connection hole to fixedly connect the connecting rod connecting member 32 and the driving arm body 31. Thus, the connecting rod connecting member 32 is detachably connected to the driving arm body 31 and the connection position is adjustable between the first end and the second end of the driving arm body 31.

[0059] Specifically, one end of the connecting rod mechanism is hinged to the connecting rod connecting member 32; The connecting rod connecting member 32 includes a limiting block portion and a hinge shaft portion. The limiting block portion is limited in the limiting groove and is provided with a connection hole corresponding to the long hole. The hinge shaft portion protrudes from the notch of the limiting groove to one side of the driving arm body 31. The other end of the connecting rod mechanism is rotatably sleeved on the hinge shaft portion to be hinged to the connecting rod connecting member 32.

[0060] Specifically, the fastener 33 can be a fastening bolt or a quick-release pin.

[0061] In one embodiment, referring to the attached Figure 3 As shown, the driving arm 3 is provided with a first positioning structure extending from the first end to the second end, and the link connecting member 32 is provided with a second positioning structure. The first positioning structure and the second positioning structure are positioned and matched to fix the position of the link connecting member 32 between the first end and the second end of the driving arm body 31.

[0062] Specifically, the first positioning structure is arranged on the inner wall of the limiting groove of the driving arm body 31 and is arranged along the extending direction of the limiting groove.

[0063] In this embodiment, when it is necessary to adjust the connection position of the link connecting member 32 between the first end and the second end of the driving arm body 31, the fastener 33 is removed or loosened, so that the link connecting member 32 can move in the limiting groove. After the link connecting member 32 is moved to the target position, the link connecting member 32 can be positioned on the driving arm body 31 through the positioning and matching of the first positioning structure and the second positioning structure. Then, the link connecting member 32 and the driving arm body 31 are tightly connected through the fastener 33. In this way, the accuracy of adjusting the connection position of the link connecting member 32 between the first end and the second end of the driving arm body 31 is effectively improved, thereby improving the accuracy of adjusting the watering amount of the watering device and realizing the precise adjustment of the watering amount.

[0064] In one embodiment, referring to the attached Figure 3 As shown, the first positioning structure is a first rack, and the second positioning structure is a second rack. The first positioning structure and the second positioning structure are meshed with each other for positioning and matching.

[0065] It can be understood that by positioning the link connecting member 32 on the driving arm body 31 in the way of mutual meshing of the racks, the positioning accuracy can be ensured.

[0066] In another embodiment, the first positioning structure is a first friction belt, and the second positioning structure is a second friction belt. The first positioning structure and the second positioning structure are attached to each other for positioning and matching.

[0067] It can be understood that by positioning the link connecting member 32 on the driving arm body 31 in the way of mutual attachment of the friction belts, the stepless adjustment of the watering amount can be realized while ensuring the positioning accuracy.

[0068] In one embodiment, referring to the attached Figure 2 and the attached Figure 4 As shown, the watering device further includes a mounting bracket 8, and the link mechanism includes:

[0069] The connecting rod 4 has its first end hinged to the connecting rod connector 32.

[0070] The rocker 5 has its first end hinged to the extending end of the piston rod 21, and its second end hinged to the second end of the connecting rod 4. The rocker 5 has a hinged section located between the first end and the second end, and the hinged section of the rocker 5 is hinged to the mounting bracket 8. The distance between the second end of the rocker 5 and the hinged section is greater than the distance between the first end of the rocker 5 and the hinged section.

[0071] Wherein, the rotation axis of the driving arm body 31, the hinge axis at the hinge joint between the connecting rod 4 and the connecting rod connector 32, the hinge axis at the hinge joint between the connecting rod 4 and the rocker 5, and the hinge axis at the hinge joint between the rocker 5 and the piston rod 21 are all arranged in the same direction.

[0072] In actual application, the mounting bracket 8 can be fixedly installed on the power take-off box of the transplanter.

[0073] In this embodiment, the driving arm body 31 rotates around the first end to drive the connecting rod 4 to swing, thereby driving the rocker 5 to swing around the hinge joint with the mounting bracket 8, and then driving the piston rod 21 to move axially to achieve watering.

[0074] It can be understood that the rocker 5, the connecting rod 4, the piston rod 21 and the mounting bracket 8 form a lever structure. With such a setting, it can make it more labor-saving for the driving arm 3 to drive the piston in the piston-type water pump 2 to move, that is, effectively reduce the power requirement for the watering operation of the watering device. At the same time, it also effectively ensures the accuracy of adjusting the watering volume of the watering device.

[0075] In one embodiment, referring to the attached Figure 2 and the attached Figure 4 As shown, the end of the piston-type water pump 2 far from the piston rod 21 is movably connected to the mounting bracket 8, and the piston rod 21 is arranged at an angle with the rocker 5. With such a setting, the overall structure of the watering device can be made more compact, reducing the overall volume of the watering device.

[0076] Specifically, the end of the piston-type water pump 2 far from the piston rod 21 is hinged to the mounting bracket 8.

[0077] In one embodiment, referring to the attached Figure 1 As shown, the watering device includes two water storage tanks 1. The piston-type water pump 2, the driving arm 3 and the connecting rod mechanism are all located between the two water storage tanks 1. The two water storage tanks 1 are interconnected through an intermediate pipeline, and the water inlet of the piston-type water pump 2 is communicated with the intermediate pipeline through a water inlet pipeline. With such a setting, the watering device can continuously water for a long time. While making the overall structure of the watering device more compact, the two water storage tanks 1 can play a certain protective role for the piston-type water pump 2, the driving arm 3 and the connecting rod mechanism, effectively improving the service life and operation reliability of the watering device.

[0078] In one embodiment, referring to the appendix Figure 4 As shown, a check valve is provided on the water inlet pipe.

[0079] By providing the check valve, water can only enter the piston pump 2 from the water storage tank 1, avoiding the problem that water flows back into the water storage tank 1 during the watering operation, thus affecting the watering amount.

[0080] In one embodiment, referring to the appendix Figure 4 As shown, a check valve is provided on the watering pipe.

[0081] By providing the check valve, water can only flow out from the piston pump 2 and water outward through the watering pipe, avoiding the problem that water flows back into the piston pump 2 during the watering operation, thus affecting the watering amount.
