Description

Technical Field

[0001] The present invention relates to the technical field of sprayers, and in particular to a spray rod fixing seat installation structure and a sprayer. Background Art

[0002] Most of the spray boom mounts on the market are fixed. The spray boom is installed on the spray boom mount. The spray boom has only two use states: extended to the working position for work and retracted to the retracted position. The spray boom can only be retracted to a fixed position. However, as sprayers become larger and smarter, the size of the sprayer increases, the number of installed equipment increases, and the space occupied by the sprayer increases. The spray boom in the retracted state exceeds the road transportation width, which is not convenient for road transportation. Summary of the invention

[0003] The present invention provides a spray boom fixing seat installation structure and a spray machine, which can realize the spray boom to any length extension and retraction through the movement of the spray boom fixing seat, thereby improving the technical problem that the spray boom in a contracted state exceeds the road transportation width and is inconvenient for road transportation.

[0004] The technical solution of the present invention to solve the above technical problems is as follows:

[0005] On the one hand, the present invention provides a spray rod fixing seat installation structure, including an electric push rod for installation on a spray machine chassis and an inner telescopic beam having one end connected to a piston end of the electric push rod, the other end of the inner telescopic beam being used to connect to the spray rod fixing seat, and the piston end of the electric push rod being telescopic along the width direction of the spray machine chassis.

[0006] The beneficial effects of the present invention are as follows: during use, the inner telescopic beam is pushed to move by the extension and retraction of the electric push rod, thereby driving the spray rod fixing seat and the spray rod installed on the spray rod fixing seat to move, completing the extension or retraction action of the spray rod relative to the spray machine body, and through the setting of the electric push rod, the spray rod and the spray rod fixing seat can perform accurate extension or retraction actions of any length within the travel range of the electric push rod, solving the problem that the mechanical limit has only two limit modes of maximum and minimum, and improving the technical problem that the spray rod limited to the retracted state exceeds the road transportation width during actual use, which is inconvenient for road transportation.

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

[0008] Furthermore, it also includes a crossbeam, which is used to be fixed to the chassis of the sprayer, and the crossbeam is a through-hole structure along the width direction of the chassis of the sprayer, the electric push rod is installed in the crossbeam, and the other end of the inner telescopic beam extends out of the opening of the crossbeam.

[0009] The beneficial effect of adopting the above further scheme is that the crossbeam is fixed to the chassis of the sprayer, which can improve the structural strength of the chassis of the sprayer, and the electric push rod and the inner telescopic beam are both installed on the crossbeam, and the crossbeam relatively 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 connecting piece, 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 shaft with a middle end connected to the other end of the head end positioning seat, and both ends of the head end pin shaft are fixedly connected to the inner wall of the inner telescopic beam.

[0011] The beneficial effect of adopting the above further scheme is: when the electric push rod and the inner telescopic beam are connected and installed, the first end positioning seat is connected to the piston end of the electric push rod, and then 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 head-end connecting member also includes two head-end positioning blocks and at least one positioning screw, the two head-end positioning blocks are respectively fixedly connected to the two opposite inner walls of the inner telescopic beam, and the two ends of the head-end pin shaft are respectively inserted into the two head-end positioning blocks, and each positioning screw is threadedly connected to any head-end positioning block and threadedly connected to the head-end pin shaft.

[0013] The beneficial effect of adopting the above further scheme is: when the electric push rod and the inner telescopic beam are connected and installed, the head end pin shaft is passed through one of the head end positioning blocks, the other end of the head end positioning seat and the other head end positioning block in turn, and then each positioning screw is threadedly connected and installed, and finally the two head end positioning blocks are fixedly connected to the two opposite inner walls of the inner telescopic beam respectively.

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

[0015] The beneficial effect of adopting the above further scheme is: when the electric push rod and the crossbeam are connected and installed, the tail end positioning seat is connected to the body of the electric push rod, and then the tail end pin shaft is connected to the tail end positioning seat, and the tail end pin shaft is connected to the crossbeam, so as to realize the positioning installation of the electric push rod and keep the position of the electric push rod fixed during use.

[0016] Furthermore, the tail end connecting member also includes two tail end positioning blocks respectively fixedly connected to the two opposite side walls of the beam, a gasket sleeved on one end of the tail end pin shaft and a positioning pin inserted into one end of the tail end pin shaft, one end of the tail end pin shaft simultaneously passes through the tail end positioning seat, the beam 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 beam, the positioning pin is located on the outer side of the side wall of the beam, and the other end of the tail end pin shaft abuts against the other tail end positioning block.

[0017] The beneficial effect of adopting the above further scheme is: when the electric push rod and the inner telescopic beam connected as one are inserted into the cross beam from the open end of the cross beam at the same time, the electric push rod can be fixedly installed. At this time, one end of the tail end pin shaft is passed through the tail end positioning seat, the cross beam and the two tail end positioning blocks at the same time, and a gasket is put on the end of the tail end pin shaft extending out of the side wall of the cross beam, and the positioning pin is inserted.

[0019] The beneficial effect of adopting the above further scheme is: in the process of realizing the movement of the inner telescopic beam by the electric push rod, each guide plate always supports the inner telescopic beam to ensure the movement stability of the inner telescopic beam, and utilizes multiple guide plates spaced apart along the length direction of the beam to form a guiding and limiting effect, thereby ensuring the linear movement of the inner telescopic beam and further ensuring the stable movement of the spray rod fixing seat.

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

[0021] The beneficial effect of adopting the above further scheme is: 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 direction of the beam under the drive of the electric push rod, reduces the resistance caused by friction, and thus improves the operation efficiency of the entire system; at the same time, the nylon plate serves as a buffer layer, which can effectively prevent the inner telescopic beam from directly colliding or wearing with the guide plate during movement, so as to extend the service life of the inner telescopic beam and the guide plate, and can also avoid component damage or performance degradation caused by long-term friction.

[0022] Furthermore, each guide plate is installed with at least one pressure screw, the head of each pressure screw is pressed against the guide plate, the rod of each pressure screw passes through the guide plate and the side wall of the beam at the same time, and is threadedly connected with a nut, which abuts against the outer wall of the beam.

[0023] The beneficial effect of adopting the above further scheme is: before installing the inner telescopic beam, the guide plate is first installed on the inner wall of the beam. During the installation process, the rod of each pressure screw is simultaneously passed through the through holes reserved in the guide plate and the side wall of the beam, and then the nut is tightened, so that the pressure screw can apply pressure to the guide plate through the nut.

[0024] On the other hand, the present invention provides a sprayer, comprising the above-mentioned spray rod fixing seat installation structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0043] On the one hand, the present invention provides a spray boom fixing seat installation structure, which is described in detail below.

[0044] Example 1

[0045] like Figures 1 to 4 A spray rod fixing seat installation structure includes an electric push rod 3 for installation on a spray machine 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 rod fixing seat 11, and the piston end of the electric push rod 3 is telescopic along the width direction of the spray machine chassis 1.

[0046] The beneficial effect of this embodiment is that during use, the inner telescopic beam 4 is pushed to move by the extension and retraction of the electric push rod 3, thereby driving the spray rod fixing seat 11 and the spray rod installed on the spray rod fixing seat 11 to move, completing the extension or retraction action of the spray rod relative to the spray machine body, and through the setting of the electric push rod 3, the spray rod and the spray rod fixing seat 11 can perform accurate extension or retraction actions of any length within the travel range of the electric push rod 3, solving the problem that the mechanical limit has only two maximum and minimum limit modes, and improving the technical problem that the spray rod limited to the retracted state exceeds the road transportation width during actual use, which is not convenient for road transportation.

[0047] In this embodiment, an electric push rod 3 is used to drive the telescopic structure instead of manually stretching it, thereby solving the problem that the telescopic structure is difficult to push because the structure does not move for a long time or the structure is relatively large, and the electric push rod 3 can stop accurately at any point within the travel range.

[0048] The inner telescopic beam 4 may be a square steel beam structure with a hollow interior and 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 spray machine chassis 1 on the horizontal plane, so as to ensure that the installation of the electric push rod 3 does 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 is bent laterally to be fixedly connected to the spray boom fixing seat 11, thereby achieving a fixed connection with the spray boom fixing seat 11.

[0051] Example 2

[0052] like Figures 2 to 4 On the basis of Example 1, the spray rod fixing seat installation structure also includes a crossbeam 2, which is used to be fixed to the sprayer chassis 1, and the crossbeam 2 is a through hole structure along the width direction of the sprayer chassis 1, the electric push rod 3 is installed in 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 embodiment is that the crossbeam 2 is fixed to the sprayer chassis 1, which can improve the structural strength of the sprayer chassis 1, and the electric push rod 3 and the inner telescopic beam 4 are both installed on the crossbeam 2, and the crossbeam 2 relatively 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] The crossbeam 2 may be made of a hollow aluminum alloy material to reduce weight and ensure structural strength.

[0055] Example 3

[0056] like Figures 2 to 6 On the basis of Examples 1 and 2, the spray rod fixing seat installation structure also includes a head end connecting member 5, the head end connecting member 5 includes a head end positioning seat 51 having one end connected to the piston end of the electric push rod 3 and a head end pin shaft 52 having a middle end connected to the other end of the head end positioning seat 51, and both ends of the head end pin shaft 52 are fixedly connected to the inner wall of the inner telescopic beam 4.

[0057] The beneficial effect of adopting the preferred scheme in the above embodiment is that when the electric push rod 3 and the inner telescopic beam 4 are connected and installed, the first end positioning seat 51 is connected to the piston end of the electric push rod 3, and then the first end pin shaft 52 is connected to the first end positioning seat 51, and the first end pin shaft 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 thrust or pull of the electric push rod 3 is smoothly transmitted to the inner telescopic beam 4 through the head end connecting piece 5 .

[0059] As a specific solution of the above embodiment, the head end positioning seat 51 can be installed by welding, screwing, plugging, etc. A through hole structure is provided at the other end of the head end positioning seat 51 for the head end pin shaft 52 to pass through, so as to install the head end pin shaft 52.

[0060] As one of the parallel schemes of this embodiment, the cross-section of the first end pin shaft 52 is circular, that is, the first end pin shaft 52 is cylindrical, so that when the electric push rod 3 pushes or pulls the inner telescopic beam 4, the vibration that may be generated during the operation of the sprayer is alleviated through the rotation of the first end pin shaft 52, thereby achieving a flexible connection, ensuring that the electric push rod 3 drives the inner telescopic beam 4 smoothly, so that the inner telescopic beam 4 moves smoothly.

[0061] As one of the parallel solutions of this embodiment, the cross section of the head end pin 52 is polygonal, such as a triangle, a quadrilateral, etc. At this time, the side of the head end pin 52 is used to form a limit, so that the electric push rod 3, the head end pin 52 and the inner telescopic beam 4 cannot rotate relative to each other, ensuring that the electric push rod 3, the head end pin 52 and the inner telescopic beam 4 are always located on the same straight line.

[0062] Example 4

[0063] like Figures 2 to 6 On the basis of Examples 1-3, the head-end connecting member 5 also includes two head-end positioning blocks 53 and at least one positioning screw 54. The two head-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 head-end pin shaft 52 are respectively inserted into the two head-end positioning blocks 53. Each positioning screw 54 is threadedly connected to any head-end positioning block 53 and is threadedly connected to the head-end pin shaft 52.

[0064] The beneficial effect of adopting the preferred scheme in the above embodiment is that when the electric push rod 3 and the inner telescopic beam 4 are connected and installed, the head end pin shaft 52 is passed through one of the head end positioning blocks 53, the other end of the head end positioning seat 51 and the other head end positioning block 53 in turn, and then each positioning screw 54 is threadedly connected and installed, and finally the two head end positioning blocks 53 are fixedly connected to the two opposite inner walls of the inner telescopic beam 4 respectively.

[0065] When the electric push rod 3 and the inner telescopic beam 4 need to be installed on the cross beam 2, the electric push rod 3 and the inner telescopic beam 4 connected as one are inserted into the cross beam 2 from the open end of the cross beam 2 at the same time, and finally the electric push rod 3 is fixedly installed and the inner telescopic beam 4 is connected to the spray rod fixing seat 11.

[0066] As a specific solution of the above embodiment, a threaded hole is opened on the side wall of at least one head end positioning block 53 , and a socket corresponding to the threaded hole is opened on the side of the head end pin shaft 52 to realize the installation of the positioning screw 54 .

[0067] As one of the specific solutions, at least one positioning screw 54 is threadedly connected to one of the head end positioning blocks 53. Only one positioning screw 54 is shown in the figure, but there may also be two, three, or four positioning screws.

[0068] As a second specific solution, at least one positioning screw 54 is threadedly connected to the two head end positioning blocks 53 , and the number of the positioning screws 54 on each head end positioning block 53 can be one, two, three, four, etc.

[0069] Example 5

[0070] like Figure 1 , Figure 3 , Figure 4 , Figure 7 as well as Figure 8 On the basis of Examples 1-4, the spray rod fixing seat installation structure also includes a tail end connecting member 6, which includes a tail end positioning seat 61 connected to the body of the electric push rod 3 at one end and a tail end pin shaft 62 connected to the other end of the tail end positioning seat 61 at the middle end, and both ends of the tail end pin shaft 62 are connected to the cross beam 2.

[0071] The beneficial effect of adopting the preferred scheme in the above embodiment is that when the electric push rod 3 and the cross beam 2 are connected and installed, the tail end positioning seat 61 is connected to the body of the electric push rod 3, and then the tail end pin shaft 62 is connected to the tail end positioning seat 61, and the tail end pin shaft 62 is connected to the cross beam 2, so that the positioning installation of the electric push rod 3 can be achieved, and the position of the electric push rod 3 during use can be kept fixed.

[0072] As a specific solution of the above embodiment, the tail end positioning seat 61 can be installed by welding, screwing, plugging, etc. A through hole structure is provided at the other end of the tail end positioning seat 61 for the tail end pin shaft 62 to pass through, so as to install the tail end pin shaft 62.

[0073] As one of the parallel schemes of this embodiment, the cross-section of the tail pin 62 is circular, that is, the tail pin 62 is cylindrical, so that when the electric push rod 3 pushes or pulls the inner telescopic beam 4, the vibration that may be generated during the operation of the sprayer and the electric push rod 3 is alleviated through the rotation of the tail pin 62, thereby achieving a flexible connection, ensuring that the electric push rod 3 drives the inner telescopic beam 4 smoothly, and the inner telescopic beam 4 moves smoothly.

[0074] As one of the parallel solutions of this embodiment, the cross section of the tail pin 62 is polygonal, such as a triangle, a quadrilateral, etc. At this time, the side of the tail pin 62 is used to form a limit, so that the electric push rod 3, the tail pin 62 and the crossbeam 2 cannot rotate relative to each other.

[0075] Example 6

[0076] like Figure 1 , Figure 3 , Figure 4 , Figure 7 as well as Figure 8 On the basis of Examples 1-5, the tail end connector 6 also includes two tail end positioning blocks 63 respectively fixedly connected to the two opposite side walls of the beam 2, a gasket 64 sleeved on one end of the tail end pin shaft 62, and a positioning pin 65 inserted into one end of the tail end pin shaft 62. One end of the tail end pin shaft 62 passes through the tail end positioning seat 61, the beam 2 and one of the tail end positioning blocks 63 at the same time. One of the tail end positioning blocks 63 is located on the inner side of the side wall of the beam 2, the positioning pin 65 is located on the outer side of the side wall of the beam 2, and the other end of the tail end pin shaft 62 abuts against the other tail end positioning block 63.

[0077] The beneficial effect of adopting the preferred scheme in the above embodiment is that when the electric push rod 3 and the inner telescopic beam 4 connected as one are simultaneously inserted into the beam 2 from the open end of the beam 2, the electric push rod 3 can be fixedly installed. At this time, one end of the tail end pin shaft 62 is simultaneously passed through the tail end positioning seat 61, the beam 2 and the two tail end positioning blocks 63, and the gasket 64 is sleeved on the end of the tail end pin shaft 62 extending out of the side wall of the beam 2, and the positioning pin 65 is inserted.

[0078] During use, the electric push rod 3 is positioned and installed by the tail end pin shaft 62 to keep the position of the electric push rod 3 fixed during use.

[0079] As a specific solution of the above embodiment, through holes are opened on two opposite side walls of the cross beam 2, and the two tail end positioning blocks 63 are both through hole structures for the rod portion of the tail end pin shaft 62 to pass through.

[0080] The tail pin 62 is in a “T” shape, 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 surface of one of the tail positioning blocks 63 .

[0081] Example 7

[0082] like Figures 4 to 6 On the basis of embodiments 1-6, it also includes a plurality of guide plates 7 fixedly connected to the inner wall of the beam 2, the plurality of guide plates 7 are spaced apart along the length direction of the beam 2, and each inner wall around the beam 2 is fixedly connected to a plurality of guide plates 7, and the other side of each guide plate 7 away from the beam 2 abuts against the outer wall of the inner telescopic beam 4.

[0083] The beneficial effect of adopting the preferred scheme in the above embodiment is that in the process of realizing 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, and utilizes the multiple guide plates 7 distributed at intervals along the length direction of the cross beam 2 to form a guiding and limiting effect, thereby ensuring the linear movement of the inner telescopic beam 4, and further ensuring the stable movement of the spray rod fixing seat 11.

[0084] As a specific solution of the above embodiment, the cross section of the beam 2 is a rectangular ring structure, forming four inner walls of upper, lower, left and right, and a plurality of guide plates 7 are fixedly connected to the four inner walls.

[0085] On the same inner wall of the cross beam 2 , such as the upper inner wall, at least two guide plates 7 are arranged at intervals along the length direction of the cross beam 2 .

[0086] Example 8

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

[0088] The beneficial effect of adopting the preferred scheme in the above embodiment is that by providing the nylon plate 71, the friction between the inner telescopic beam 4 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, reduces the resistance caused by friction, and thus improves the operation efficiency of the entire system; at the same time, the nylon plate 71 serves as a buffer layer, which can effectively prevent the inner telescopic beam 4 from directly colliding or wearing with the guide plate 7 during movement, so as to extend the service life of the inner telescopic beam 4 and the guide plate 7, and can also avoid component damage or performance degradation caused by long-term friction.

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

[0090] Furthermore, the low friction property of the nylon plate 71 helps to reduce the noise generated by the inner telescopic beam 4 during movement.

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

[0092] Example 9

[0093] like Figures 4 to 6On the basis of Examples 1-8, each guide plate 7 is installed with at least one pressure screw 8, the head of each pressure screw 8 is pressed against the guide plate 7, the rod of each pressure screw 8 passes through the side wall of the guide plate 7 and the beam 2 at the same time, and is threadedly connected with a nut 81, which abuts against the outer wall of the beam 2.

[0094] The beneficial effect of adopting the preferred scheme in the above embodiment is that before installing the inner telescopic beam 4, the guide plate 7 is first installed on the inner wall of the beam 2. During the installation process, the rod of each pressure screw 8 is simultaneously passed through the through holes reserved in the guide plate 7 and the side wall of the beam 2, and then the nut 81 is tightened, so that the pressure screw 8 can apply pressure to the guide plate 7 through the nut 81.

[0095] As a specific solution of the above embodiment, a countersunk hole is opened on the guide plate 7 for the head of the pressure screw 8 to enter, and after the nylon plate 71 is fixed to the side of the guide plate 7, the nylon plate 71 will not bulge due to the head of the pressure screw 8, thereby affecting the movement of the inner telescopic beam 4.

[0096] In another aspect, the present invention provides a sprayer, as described in detail below.
