[0002] Most sprayer boom mounts on the market are fixed, with the boom installed on the mount. The boom has only two operating states: extended to the working position and retracted to the retracted position. The sprayer boom can only be retracted to a fixed position. However, with the increasing size and intelligence of sprayers, the overall size of the sprayer has increased, and more equipment has been installed, resulting in a greater space occupation. The retracted boom, which is limited by the road width, is inconvenient for road transport. Utility Model Content

[0003] This utility model provides a spray boom mounting structure and a sprayer, which can achieve arbitrary length extension and retraction of the spray boom through the movement of the spray boom mounting base, thereby improving the technical problem that the spray boom in the retracted state exceeds the road transport width and is inconvenient for road transport.

The other end of the inner telescopic beam is used to connect to the spray boom mounting base. The piston end of the electric push rod extends and retracts along the width direction of the sprayer chassis.

[0006] The beneficial effects of this utility model are as follows: During use, the extension and retraction of the electric push rod pushes the inner telescopic beam to move, thereby driving the spray boom fixing seat and the spray boom installed on the spray boom fixing seat to move, completing the extension or retraction action of the spray boom relative to the sprayer body. Through the setting of the electric push rod, the spray boom and the spray boom fixing seat can perform precise extension or retraction actions of any length within the stroke range of the electric push rod, solving the problem that mechanical limit has only two limit methods, maximum and minimum, and improving the technical problem that the spray boom in the retracted state exceeds the road transport width and is inconvenient for road transport during actual use.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, it also includes a crossbeam for fixing to the sprayer chassis, and the crossbeam has a through hole structure along the width direction of the sprayer chassis. The electric push rod is installed inside the crossbeam, and the other end of the inner telescopic beam extends out of the opening of the crossbeam.

[0009] The beneficial effects of adopting the above-mentioned further solution are: the crossbeam is fixed to the sprayer chassis, which can improve the structural strength of the sprayer chassis; and the electric push rod and the inner telescopic beam are both installed on the crossbeam, and the crossbeam forms a closed installation space, which can protect the electric push rod and ensure the normal operation of the electric push rod and the normal extension and retraction of the inner telescopic beam.

[0010] Furthermore, it also includes a head end connector, which includes a head end positioning seat with one end connected to the piston end of the electric push rod and a head end pin with the middle end connected to the other end of the head end positioning seat. Both ends of the head end pin are fixedly connected to the inner wall of the inner telescopic beam.

[0011] The beneficial effect of adopting the above-mentioned further solution is that when connecting and installing the electric push rod and the inner telescopic beam, the first end positioning seat is connected to the piston end of the electric push rod, the first end pin is connected to the first end positioning seat, and the first end pin is fixedly connected to the inner telescopic beam.

[0012] Furthermore, the first end connector also includes two first end positioning blocks and at least one positioning screw. The two first end positioning blocks are respectively fixedly connected to the two opposite inner walls of the inner telescopic beam, and the two ends of the first end pin are respectively inserted into the two first end positioning blocks. Each positioning screw is threadedly connected to any one of the first end positioning blocks and threadedly connected to the first end pin.

[0013] The beneficial effect of adopting the above-mentioned further solution is that when connecting and installing the electric push rod and the inner telescopic beam, the first end pin is passed through one of the first end positioning blocks, the other end of the first end positioning seat and the other first end positioning block in sequence, and then the positioning screws are threaded together and installed. Finally, the two first end positioning blocks are fixedly connected to the two opposite inner walls of the inner telescopic beam.

[0014] Furthermore, it also includes a tail end connector, which includes a tail end positioning seat connected at one end to the electric push rod body and a tail end pin connected at the other end of the tail end positioning seat in the middle, with both ends of the tail end pin connected to the crossbeam.

[0015] The beneficial effect of adopting the above-mentioned further solution is that when connecting and installing the electric push rod and the crossbeam, the tail end positioning seat is connected to the body of the electric push rod, and then the tail end pin is connected to the tail end positioning seat and the tail end pin is connected to the crossbeam. This can achieve the positioning and installation of the electric push rod and keep the position of the electric push rod fixed during use.

[0016] Furthermore, the tail end connector also includes two tail end positioning blocks that are respectively fixedly connected to the two opposite side walls of the crossbeam, a washer sleeved on one end of the tail end pin, and a positioning pin inserted into one end of the tail end pin. One end of the tail end pin passes through the tail end positioning seat, the crossbeam, and one of the tail end positioning blocks. One of the tail end positioning blocks is located on the inner side of the side wall of the crossbeam, and the positioning pin is located on the outer side of the side wall of the crossbeam. The other end of the tail end pin abuts against the other tail end positioning block.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the electric push rod and the inner telescopic beam, which are connected as a whole, can be fixedly installed by inserting them into the crossbeam from the open end of the crossbeam. At this time, one end of the tail pin passes through the tail positioning seat, the crossbeam and the two tail positioning blocks at the same time, and the shim is placed on the end of the tail pin that extends out of the side wall of the crossbeam, and the positioning pin is inserted.

[0020] Furthermore, each of the guide plates is provided with a nylon plate on the other side of the inner telescopic beam, and the nylon plate abuts against the outer wall of the inner telescopic beam.

[0021] The beneficial effects of adopting the above-mentioned further solution are as follows: by setting the nylon plate, the friction between it and the inner telescopic beam can be reduced, which helps the inner telescopic beam to move more smoothly along the length of the crossbeam under the drive of the electric push rod, reducing the resistance caused by friction, thereby improving the operating efficiency of the entire system; at the same time, the nylon plate, as a buffer layer, can effectively prevent the inner telescopic beam from directly colliding or wearing with the guide plate during movement, thereby extending the service life of the inner telescopic beam and the guide plate, and also avoiding component damage or performance degradation caused by long-term friction.

[0022] Furthermore, each of the guide plates is equipped with at least one pressure screw, the head of each pressure screw is pressed against the guide plate, and the shank of each pressure screw passes outward through both the guide plate and the side wall of the crossbeam, and is threaded with a nut, the nut abutting against the outer wall of the crossbeam.

[0023] The beneficial effect of adopting the above-mentioned further solution is that: before installing the inner telescopic beam, the guide plate is first installed on the inner wall of the crossbeam. During the installation process, the shank of each pressure screw passes outward through the through hole reserved in the guide plate and the side wall of the crossbeam. Then the nut is tightened, and the pressure screw can apply pressure to the guide plate through the nut.

[0024] On the other hand, this utility model provides a sprayer, including the aforementioned spray bar fixing seat mounting structure. Attached Figure Description

[0042] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0043] On the one hand, this utility model provides a spray bar fixing seat mounting structure, as described below.

[0044] Example 1

[0045] like Figures 1 to 4 A spray boom mounting structure includes an electric push rod 3 for mounting on a sprayer chassis 1 and an inner telescopic beam 4 with one end connected to the piston end of the electric push rod 3. The other end of the inner telescopic beam 4 is used to connect to the spray boom mounting base 11, and the piston end of the electric push rod 3 extends and retracts along the width direction of the sprayer chassis 1.

[0046] The beneficial effects of this embodiment are as follows: During use, the extension and retraction of the electric push rod 3 pushes the inner telescopic beam 4 to move, thereby driving the spray boom fixing seat 11 and the spray boom installed on the spray boom fixing seat 11 to move, completing the extension or retraction action of the spray boom relative to the sprayer body. Through the setting of the electric push rod 3, the spray boom and the spray boom fixing seat 11 can perform precise extension or retraction actions of any length within the stroke range of the electric push rod 3, solving the problem that mechanical limit only has two limit methods, the maximum and the minimum, and improving the technical problem that the spray boom in the retracted state exceeds the road transport width and is inconvenient for road transport during actual use.

[0047] In this embodiment, by using an electric push rod 3 to drive the telescopic structure instead of a manual stretching structure, the problem of difficulty in pushing the telescopic structure when it is not moving for a long time or when the structure is large is solved. Moreover, within the stroke range of the electric push rod 3, it can be stopped precisely at any point.

[0048] The inner telescopic beam 4 can be a hollow square steel beam structure made of aluminum to reduce weight.

[0049] The projection of the electric push rod 3 on the horizontal plane is located within the projection plane of the sprayer chassis 1 on the horizontal plane, so as to ensure that the installation of the electric push rod 3 will not occupy additional space.

[0050] Based on the above embodiment, a bent plate 41 is fixedly connected to the other end of the inner telescopic beam 4. One end of the bent plate 41 is fixedly connected to the other end of the inner telescopic beam 4, and the other end of the bent plate 41 extends upward and bends laterally to be fixedly connected to the spray bar fixing seat 11, thereby achieving a fixed connection with the spray bar fixing seat 11.

[0051] Example 2

[0052] like Figures 2 to 4 Based on embodiment 1, the spray bar fixing seat mounting structure further includes a crossbeam 2, which is used to fix the sprayer chassis 1. The crossbeam 2 has a through hole structure along the width direction of the sprayer chassis 1. The electric push rod 3 is installed inside the crossbeam 2, and the other end of the inner telescopic beam 4 extends out of the opening of the crossbeam 2.

[0053] The beneficial effect of adopting the preferred solution in the above embodiments is that the crossbeam 2 is fixed to the sprayer chassis 1, which can improve the structural strength of the sprayer chassis 1. The electric push rod 3 and the inner telescopic beam 4 are both installed on the crossbeam 2. The crossbeam 2 forms a closed installation space, which can protect the electric push rod 3 and ensure the normal operation of the electric push rod 3 and the normal extension and retraction of the inner telescopic beam 4.

[0054] Among them, the crossbeam 2 can be made of hollow aluminum alloy material to reduce weight and ensure structural strength.

[0055] Example 3

[0056] like Figures 2 to 6 Based on embodiments 1 and 2, the spray bar fixing seat mounting structure further includes a head end connector 5. The head end connector 5 includes a head end positioning seat 51 with one end connected to the piston end of the electric push rod 3 and a head end pin 52 with the middle end connected to the other end of the head end positioning seat 51. Both ends of the head end pin 52 are fixedly connected to the inner wall of the inner telescopic beam 4.

[0057] The beneficial effect of adopting the preferred solution in the above embodiments is that when connecting and installing the electric push rod 3 and the inner telescopic beam 4, the first end positioning seat 51 is connected to the piston end of the electric push rod 3, and then the first end pin 52 is connected to the first end positioning seat 51, and the first end pin 52 is fixedly connected to the inner telescopic beam 4.

[0058] When the electric push rod 3 drives the inner telescopic beam 4 to move, the pushing or pulling force of the electric push rod 3 is smoothly transmitted to the inner telescopic beam 4 through the first end connector 5.

[0059] As a specific embodiment of the above, the first-end positioning seat 51 can be installed by welding, screwing, or plugging. Furthermore, a through hole structure is provided at the other end of the first-end positioning seat 51 for the first-end pin 52 to pass through, thereby enabling the installation of the first-end pin 52.

[0060] As one of the parallel solutions in this embodiment, the cross-section of the first end pin 52 is circular, that is, the first end pin 52 is cylindrical. In order to alleviate the vibration that may be generated during the operation of the sprayer by the rotation of the first end pin 52 during the process of pushing or pulling the inner telescopic beam 4 by the electric push rod 3, the flexible connection is achieved, ensuring that the electric push rod 3 can smoothly drive the inner telescopic beam 4, so that the inner telescopic beam 4 can move smoothly.

[0061] As one of the parallel solutions in this embodiment, the cross-section of the first end pin 52 is polygonal, such as a triangle or quadrilateral. In this case, the side of the first end pin 52 forms a limit, so that the electric push rod 3, the first end pin 52 and the inner telescopic beam 4 cannot rotate relative to each other, ensuring that the electric push rod 3, the first end pin 52 and the inner telescopic beam 4 are always on the same straight line.

[0062] Example 4

[0063] like Figures 2 to 6 Based on embodiments 1-3, the first end connector 5 further includes two first end positioning blocks 53 and at least one positioning screw 54. The two first end positioning blocks 53 are respectively fixedly connected to the two opposite inner walls of the inner telescopic beam 4, and the two ends of the first end pin 52 are respectively inserted into the two first end positioning blocks 53. Each positioning screw 54 is threadedly connected to any one of the first end positioning blocks 53 and threadedly connected to the first end pin 52.

[0064] The beneficial effect of adopting the preferred solution in the above embodiments is that when connecting and installing the electric push rod 3 and the inner telescopic beam 4, the first end pin 52 passes through one of the first end positioning blocks 53, the other end of the first end positioning seat 51 and the other first end positioning block 53 in sequence, and then the positioning screws 54 are threaded and installed. Finally, the two first end positioning blocks 53 are fixedly connected to the two opposite inner walls of the inner telescopic beam 4.

[0065] When it is necessary to install the electric push rod 3 and the inner telescopic beam 4 on the crossbeam 2, the electric push rod 3 and the inner telescopic beam 4, which are connected as one unit, are simultaneously inserted into the crossbeam 2 from the open end of the crossbeam 2. Finally, the electric push rod 3 is fixedly installed, and the inner telescopic beam 4 is connected to the spray bar fixing seat 11.

[0066] As a specific embodiment of the above, a threaded hole is provided on the side wall of at least one head positioning block 53, and an insertion hole corresponding to the threaded hole is provided on the side of the head pin 52, so as to realize the installation of the positioning screw 54.

[0067] As one of the specific solutions, at least one positioning screw 54 is threaded onto one of the head positioning blocks 53. Only one positioning screw 54 is shown in the figure, but there can also be two, three, or four, etc.

[0068] As a second specific solution, at least one positioning screw 54 is threaded onto each of the two end positioning blocks 53. The number of positioning screws 54 on each end positioning block 53 can be one, two, three, or four, etc.

[0069] Example 5

[0070] like Figure 1 , Figure 3 , Figure 4 , Figure 7 as well as Figure 8 Based on embodiments 1-4, the spray bar fixing seat mounting structure further includes a tail end connector 6. The tail end connector 6 includes a tail end positioning seat 61 with one end connected to the electric push rod 3 body and a tail end pin 62 with the middle end connected to the other end of the tail end positioning seat 61. Both ends of the tail end pin 62 are connected to the crossbeam 2.

[0071] The beneficial effect of adopting the preferred solution in the above embodiments is that when connecting and installing the electric push rod 3 and the crossbeam 2, the tail end positioning seat 61 is connected to the body of the electric push rod 3, and then the tail end pin 62 is connected to the tail end positioning seat 61 and the tail end pin 62 is connected to the crossbeam 2, so as to realize the positioning and installation of the electric push rod 3 and keep the position of the electric push rod 3 fixed during use.

[0072] As a specific embodiment of the above, the tail end positioning seat 61 can be installed by welding, screwing, or plugging. Furthermore, a through hole structure is provided at the other end of the tail end positioning seat 61 for the tail end pin 62 to pass through, thereby enabling the installation of the tail end pin 62.

[0073] As one of the parallel solutions in this embodiment, the cross-section of the tail pin 62 is circular, that is, the tail pin 62 is cylindrical. In order to alleviate the vibration that may be generated during the operation of the sprayer and the electric push rod 3 by rotating the tail pin 62 during the process of pushing or pulling the inner telescopic beam 4 through the electric push rod 3, so as to achieve a flexible connection, ensure the smooth drive of the electric push rod 3 to the inner telescopic beam 4, and enable the inner telescopic beam 4 to move smoothly.

[0074] As one of the parallel solutions in this embodiment, the cross-section of the tail pin 62 is polygonal, such as a triangle or quadrilateral. In this case, the side of the tail pin 62 forms a limit, preventing relative rotation between the electric push rod 3, the tail pin 62, and the crossbeam 2.

[0075] Example 6

[0076] like Figure 1 , Figure 3 , Figure 4 , Figure 7 as well as Figure 8 Based on embodiments 1-5, the tail end connector 6 further includes two tail end positioning blocks 63 that are respectively fixedly connected to the two opposite side walls of the crossbeam 2, a washer 64 sleeved on one end of the tail end pin 62, and a positioning pin 65 inserted into one end of the tail end pin 62. One end of the tail end pin 62 passes through the tail end positioning seat 61, the crossbeam 2, and one of the tail end positioning blocks 63. One of the tail end positioning blocks 63 is located on the inner side of the side wall of the crossbeam 2, and the positioning pin 65 is located on the outer side of the side wall of the crossbeam 2. The other end of the tail end pin 62 abuts against the other tail end positioning block 63.

[0077] The beneficial effect of adopting the preferred solution in the above embodiments is that the electric push rod 3 and the inner telescopic beam 4, which are connected as a whole, can be fixedly installed by inserting them into the crossbeam 2 from the open end of the crossbeam 2. At this time, one end of the tail pin 62 is passed through the tail positioning seat 61, the crossbeam 2 and the two tail positioning blocks 63 at the same time, and the gasket 64 is sleeved on the end of the tail pin 62 that extends out of the side wall of the crossbeam 2, and the positioning pin 65 is inserted.

[0078] During use, the electric push rod 3 is positioned and installed using the tail pin 62 to keep the electric push rod 3 in a fixed position during use.

[0079] As a specific embodiment of the above, through holes are provided on the two opposite side walls of the crossbeam 2, and both tail end positioning blocks 63 are through hole structures so that the rod part of the tail end pin 62 can pass through.

[0080] The tail pin 62 is T-shaped, and the T-shaped end is the other end of the tail pin 62, so that after the tail pin 62 is installed, the T-shaped end of the tail pin 62 abuts against the side of one of the tail positioning blocks 63.

[0081] Example 7

[0082] like Figures 4 to 6 Based on embodiments 1-6, it also includes multiple guide plates 7 fixedly connected to the inner wall of the crossbeam 2. The multiple guide plates 7 are distributed at intervals along the length direction of the crossbeam 2, and multiple guide plates 7 are fixedly connected to each inner wall around the crossbeam 2. The side of each guide plate 7 away from the crossbeam 2 abuts against the outer wall of the inner telescopic beam 4.

[0083] The beneficial effect of adopting the preferred solution in the above embodiments is that during the movement of the inner telescopic beam 4 by the electric push rod 3, each guide plate 7 always supports the inner telescopic beam 4 to ensure the movement stability of the inner telescopic beam 4. The multiple guide plates 7 distributed at intervals along the length direction of the crossbeam 2 form a guiding and limiting function to ensure the linear movement of the inner telescopic beam 4, thereby ensuring the stable movement of the spray bar fixing seat 11.

[0084] As a specific embodiment of the above, the cross-section of the beam 2 is a rectangular ring structure, forming four inner walls: upper, lower, left, and right. Each of the four inner walls is fixedly connected with multiple guide plates 7.

[0085] On the same inner wall of the crossbeam 2, such as on the upper inner wall, at least two guide plates 7 are provided at intervals along the length of the crossbeam 2.

[0086] Example 8

[0087] like Figures 4 to 6 Based on embodiments 1-7, each guide plate 7 is provided with a nylon plate 71 on the other side of the inner telescopic beam 4, and the nylon plate 71 abuts against the outer wall of the inner telescopic beam 4.

[0088] The beneficial effects of adopting the preferred solution in the above embodiments are that by setting the nylon plate 71, the friction between it and the inner telescopic beam 4 can be reduced, which helps the inner telescopic beam 4 to move more smoothly along the length direction of the crossbeam 2 under the drive of the electric push rod 3, reducing the resistance caused by friction, thereby improving the operating efficiency of the entire system; at the same time, the nylon plate 71, as a buffer layer, can effectively prevent the inner telescopic beam 4 from directly colliding or wearing with the guide plate 7 during the movement, so as to extend the service life of the inner telescopic beam 4 and the guide plate 7, and also avoid component damage or performance degradation caused by long-term friction.

[0089] The introduction of nylon plate 71 further enhances the supporting effect of guide plate 7 on inner telescopic beam 4. Due to the elasticity and wear resistance of nylon plate 71, it can provide more uniform support force during the movement of inner telescopic beam 4, thereby further ensuring the movement stability and straightness of inner telescopic beam 4.

[0090] Furthermore, the low friction properties of the nylon plate 71 also help reduce the noise generated by the inner telescopic beam 4 during movement.

[0091] The nylon plate 71 can be specifically fixed to the guide plate 7 by adhesive bonding.

[0092] Example 9

[0093] like Figures 4 to 6Based on embodiments 1-8, each guide plate 7 is equipped with at least one pressure screw 8. The head of each pressure screw 8 is pressed against the guide plate 7, and the shank of each pressure screw 8 passes outward through both the guide plate 7 and the side wall of the crossbeam 2, and is threaded with a nut 81. The nut 81 abuts against the outer wall of the crossbeam 2.

[0094] The beneficial effect of adopting the preferred solution in the above embodiments is that, before installing the inner telescopic beam 4, the guide plate 7 is first installed on the inner wall of the crossbeam 2. During the installation process, the rods of each pressure screw 8 pass outward through the through holes reserved in the guide plate 7 and the side wall of the crossbeam 2 at the same time. Then, the nut 81 is tightened, and the pressure screw 8 can apply pressure to the guide plate 7 through the nut 81.

[0095] As a specific embodiment of the above, a countersunk hole is provided on the guide plate 7 to allow the head of the pressure screw 8 to enter, so that after the nylon plate 71 is fixed to the side of the guide plate 7, the nylon plate 71 will not cause the head of the pressure screw 8 to protrude, thus affecting the movement of the inner telescopic beam 4.

[0096] On the other hand, this utility model provides a sprayer, as detailed below.
