Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of boom sprayers, in particular to an anti-collision structure at the end of a boom that can automatically flip and reset and a boom sprayer. Background Art
[0002] For large boom sprayers to improve operation efficiency, generally, the spray width is relatively large, and the spraying components are installed on the boom and extend along the length direction to both ends of the boom. Since the boom is far from the sprayer body after being unfolded and has a long cantilever, and the field is bumpy during operation, the end of the boom is extremely easy to touch the ground. In the light case, spraying components such as nozzles are damaged, and in the heavy case, the end is stuck and folded, pulling related components, causing boom failures or safety accidents of the whole machine.
[0003] At present, there are mainly two solutions for large boom sprayers on the market: one is to install rolling components such as tires at the end of the boom. When touching the ground, the tire first contacts the ground and deforms, and at the same time, it does not affect the machine's forward movement. However, components such as tires are heavy and swing with the boom during operation, which is likely to affect the spray uniformity; the other is to install deformable ground-touching components at the end of the boom. Once touching the ground, the components deform to absorb the impact and reduce the influence on the boom and its accessories. Such components are usually light in weight, easy to install, and have little influence on the boom operation. However, due to the relatively frequent ground-touching times, the deformation of the components is limited, and they lose their function after a long time. Summary of the Utility Model
[0004] The utility model provides an anti-collision structure at the end of a boom that can automatically flip and reset and a boom sprayer, aiming to solve the problems in the prior art.
[0005] The technical solution for the utility model to solve the above technical problems is as follows:
[0006] An anti-collision structure at the end of a boom that can automatically flip and reset includes a fixed section, a connecting frame, and an anti-collision component. The connecting frame is rotatably installed at one end of the fixed section, and its top is rotatably connected to the upper side of the fixed section through a folding oil cylinder; the anti-collision component is rotatably and resetably installed on the connecting frame.
[0007] The beneficial effect of the utility model is that when the sprayer encounters an obstacle during walking, the obstacle contacts the anti-collision component, and the anti-collision component will deflect and can automatically reset to protect the corresponding components on the sprayer, and the protection effect is better;
[0008] When the end of the spray boom of the sprayer suddenly touches the ground during field operation, the anti-collision component is subjected to an upward force from the ground, causing the piston rod of the folding cylinder to retract, the length of the cylinder to shorten, and the anti-collision section to tilt upward, preventing accidents such as damage; at the same time, under the action of other internal components, the hydraulic oil will return to the end of the folding cylinder after a certain time, until the cylinder returns to its initial length and the anti-collision component resumes its working state, and the operation of the spray boom sprayer continues.
[0009] The utility model realizes the folding and reset functions by using a hydraulic cylinder, which does not affect the spray uniformity. At the same time, this function can be repeatedly realized according to the actual situation, avoiding phenomena such as deformation of mechanical parts that are not easy to recover and affecting the use in the later stage and causing accidents, and solving problems such as failures and accidents of important components such as the spray boom of large sprayers due to touching the ground.
[0010] On the basis of the above technical solutions, the utility model can be further improved as follows.

[0012] The beneficial effect of adopting the above further solution is that when the sprayer encounters obstacles such as big trees during walking, the anti-collision section deflects, the upper mounting seat and the lower mounting seat are gradually separated, and at the same time, the upper mounting seat compresses the return member to cause elastic deformation, mainly relying on the wedge fit between the upper mounting seat and the lower mounting seat; under the influence of potential energy, the return member will compress the upper mounting seat downward, making it gradually fit with the lower mounting seat, driving the anti-collision section to complete the reset and return to the initial position.
[0013] Further, a wedge-shaped groove is provided at the upper end of the lower mounting seat, and a wedge-shaped protrusion is provided at the lower end of the upper mounting seat. The wedge-shaped protrusion is slidably fitted with the wedge-shaped groove.
[0014] The beneficial effect of adopting the above further solution is that the structure is simple and the design is reasonable. The wedge-shaped groove on the lower mounting seat and the wedge-shaped protrusion on the upper mounting seat are used in cooperation to deflect the anti-collision section, thereby protecting the sprayer.
[0015] Further, the return member includes a first pin shaft, a second pin shaft and a spring. The first pin shaft passes through the upper end of the connecting frame, the upper mounting seat and the lower mounting seat; the spring is movably sleeved on the first pin shaft, and its two ends are respectively abutted against the upper end of the connecting frame and the upper mounting seat; the two ends of the second pin shaft are respectively rotatably connected to the upper end of the first pin shaft and the middle part of the anti-collision section.
[0016] The beneficial effect of adopting the above further scheme is that when the sprayer encounters obstacles such as big trees during walking, the anti-collision section rotates with the pin shaft I as the rotation axis, deflects, the upper mounting seat and the lower mounting seat are gradually separated, and at the same time the upper mounting seat compresses the spring to cause elastic deformation of it. Here, it mainly depends on the wedge fit between the upper mounting seat and the lower mounting seat; under the influence of potential energy, the spring will compress the upper mounting seat downward, making it gradually fit with the lower mounting seat, driving the anti-collision section to complete the reset and return to the initial position;
[0017] When the end of the spray bar suddenly touches the ground during the field operation of the sprayer, the anti-collision section is subjected to an upward acting force from the ground, causing the piston rod of the folding cylinder to retract, the length of the cylinder to become shorter, and the anti-collision section to tilt upward to prevent accidents such as damage; at the same time, after a certain period of time, the oil will return to the end of the folding cylinder under the action of other internal components until the cylinder returns to its initial length and the anti-collision section resumes its working state, and the operation of the spray bar sprayer continues.
[0018] Further, the upper end of the connecting frame is provided with a U-shaped groove penetrating both sides, the pin shaft I penetrates both sides of the opening side of the U-shaped groove, and the upper end of the spring abuts against the lower side of the opening side of the U-shaped groove; a sleeve is rotatably sleeved on the part of the pin shaft I corresponding to the inside of the U-shaped groove, one end of the pin shaft II is fixedly connected to the sleeve, and the other end is rotatably connected to the anti-collision section.
[0019] The beneficial effect of adopting the above further scheme is that the structure is simple, and the U-shaped groove provided at the upper end of the connecting frame is reasonably arranged, which is convenient for assembling the spring and the pin shafts I and II, and the assembly is convenient.
[0020] Further, anti-collision blocks are relatively fixedly installed on both sides of the lower end of the anti-collision section.
[0021] The beneficial effect of adopting the above further scheme is that the structure is simple and the design is reasonable, and the anti-collision blocks can play an effective shock absorption effect.
[0022] Further, the two anti-collision blocks are respectively rubber blocks.
[0023] The beneficial effect of adopting the above further scheme is that the rubber blocks are reasonably selected, which can not only play an effective shock absorption effect, but also have low cost. The rubber blocks are convenient to purchase and are easy to repair.
[0024] Further, fixing plates are relatively fixedly installed on both sides of one end of the fixed section, the lower end of the connecting frame extends between the two fixing plates, and is rotatably connected to the two fixing plates through a pin shaft III.
[0025] The beneficial effect of adopting the above further scheme is that the end structure of the fixed section is reasonably designed, which is convenient for assembling the connecting frame.
[0026] Furthermore, anti-collision plates are fixedly installed opposite to each other on the sides of the two fixing plates that are away from each other.
[0027] The beneficial effect of adopting the above further solution is that when the collision is relatively large, the anti-collision blocks installed on the anti-collision sections touch the anti-collision plates, playing a role in shock absorption.
[0028] The present utility model also relates to a boom sprayer, which includes the anti-collision structure at the end of the boom that can be automatically flipped and reset as described above.

[0041] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.
[0042] Embodiment 1
[0043] As Figures 1 to 6 shown, this embodiment provides an anti-collision structure at the end of a spray boom that can automatically flip and reset, including a fixed section 1, a connecting frame 12, and an anti-collision component.

[0044] When the sprayer encounters an obstacle during walking, the obstacle contacts the anti-collision component, and the anti-collision component will deflect, and the anti-collision component can automatically reset to protect the corresponding components on the sprayer, and the protection effect is better;
[0045] When the end of the spray boom suddenly touches the ground during the field operation of the sprayer, the anti-collision component is subjected to an upward force from the ground, causing the piston rod of the folding cylinder 2 to retract, the length of the cylinder to shorten, and the anti-collision section to tilt upward, preventing accidents such as damage; at the same time, under the action of other internal components, the hydraulic oil will return to the cylinder end of the folding cylinder 2 after a certain period of time until the cylinder resumes its initial length and the anti-collision component resumes its working state, and the operation of the spray boom sprayer continues.
[0046] It should be noted that the above-mentioned folding cylinder 2 adopts the existing technology, and its specific structure and principle will not be elaborated here.
[0047] This embodiment uses a hydraulic cylinder to achieve the folding and reset functions, which does not affect the spray uniformity. At the same time, this function can be repeatedly realized according to the actual situation, avoiding phenomena such as deformation of mechanical parts that are not easily restored and affecting the use in the later stage, and solving problems such as failures and accidents of important components such as the spray boom of large sprayers due to touching the ground.

[0050] When the sprayer encounters obstacles such as big trees during walking, the anti-collision section 4 deflects, the upper mounting seat 8 and the lower mounting seat 7 are gradually separated, and at the same time, the upper mounting seat compresses the return member to cause elastic deformation. Here, it mainly depends on the wedge-shaped fit between the upper mounting seat 8 and the lower mounting seat 7; under the influence of potential energy, the return member will compress the upper mounting seat 8 downward, making it gradually fit with the lower mounting seat 7, driving the anti-collision section 4 to complete the reset and return to the initial position.

Here, it mainly depends on the wedge fit between the upper mounting seat 8 and the lower mounting seat 7. Under the influence of potential energy, the spring 9 will compress the upper mounting seat 8 downward, making it gradually fit with the lower mounting seat 7, driving the anti-collision section 4 to complete the reset and return to the initial position.
[0057] When the end of the spray boom suddenly touches the ground during the field operation of the sprayer, the anti-collision section 4 receives an upward force from the ground, causing the piston rod of the folding cylinder 2 to retract, the length of the cylinder to become shorter, and the anti-collision section 4 to tilt upward to prevent accidents such as damage. At the same time, under the action of other internal components, the hydraulic oil will return to the cylinder end of the folding cylinder 2 after a certain time until the cylinder returns to its initial length and the anti-collision section 4 resumes its working state, and the operation of the boom sprayer continues.

[0082] When the end of the spray boom suddenly touches the ground during the field operation of the sprayer, the anti-collision section 4 receives an upward force from the ground, causing the piston rod of the folding cylinder 2 to retract, the length of the cylinder to become shorter, and the anti-collision section 4 to tilt upward, preventing accidents such as damage; at the same time, under the action of other internal components, the oil will return to the end of the folding cylinder after a certain time until the cylinder returns to its initial length and the anti-collision section 4 resumes its working state, and the spray boom sprayer operation continues.
