Description

Technical Field

[0001] This utility model relates to the field of sprayer technology, and in particular to an adaptive balance spray bar holder and a sprayer. Background Technology

[0002] Large boom sprayers, designed to improve operational efficiency, typically have a wide spray width. The spraying element is mounted on a boom that extends along its length to both ends, and the boom is supported by a boom mount fixed to the chassis. Due to the long cantilever of the boom during deployment, coupled with uneven field conditions and mechanical vibrations, the boom tilts at a small angle (generally less than 5°) during both deployment and retraction. Consequently, when the boom retracts to the boom mount, the slightly tilted boom makes line contact with the mount, causing instability during boom retraction. Utility Model Content

[0003] This invention addresses the technical problem of unstable spray boom retrieval caused by the existing spray boom retraction being in a line contact state when it is retracted to the spray boom holder, and provides an adaptive balancing spray boom holder and sprayer.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] On one hand, this utility model provides an adaptive balance spray bar fixing base, including a vertically inclined vertical rod assembly, a horizontally arranged base assembly, and a rotating shaft assembly fixedly connected to one end of the base assembly, wherein the rotating shaft assembly is rotatably connected to the lower end of the vertical rod assembly.

[0006] The beneficial effects of this utility model are as follows: When the spray bar is retracted, the spray bar moves downward and is retracted guided by the vertical rod assembly. When the spray bar comes into contact with the base assembly, the base assembly is subjected to force under the action of the spray bar's own weight and rotates adaptively around the central axis of the rotating shaft assembly. This allows the base assembly to provide surface contact support for the spray bar, ensuring that the spray bar is stably supported. This improves the existing technical problem that the existing spray bar is in a line contact state when it is retracted to the spray bar fixing seat, resulting in unstable spray bar retraction.

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

[0008] Furthermore, the vertical rod assembly includes at least two spaced-apart No. 1 limiting plates, and the base assembly includes a connecting seat with a downward opening structure forming a mounting groove. The upper end of each No. 1 limiting plate extends into the mounting groove. The rotating shaft assembly is installed in the mounting groove, and its middle end is rotatably connected to the upper end of each No. 1 limiting plate, and both ends are fixedly connected to the connecting seat.

[0009] The beneficial effect of adopting the above-mentioned further solution is that when the base assembly is subjected to force and rotates adaptively with the rotating shaft assembly as the central axis, the connecting seat rotates simultaneously with the rotating shaft assembly as the central axis relative to each of the No. 1 limiting plates, so that the upper ends of each of the No. 1 limiting plates in the radial direction of the rotating shaft assembly can contact the bottom of the mounting groove. That is, each of the No. 1 limiting plates limits the rotation of the connecting seat, thereby controlling the angle of adaptive rotation of the base assembly and the spray bar supported by it, ensuring stable support after the spray bar is retracted, and controlling the adaptive rotation of the spray bar within a small angle.

[0010] Furthermore, the vertical rod assembly also includes a vertically inclined vertical plate, and the lower end of each of the first limiting plates is fixedly connected to the lower end of the vertical plate; the base assembly also includes a base, and one end of the connecting seat is detachably connected to one end of the base.

[0011] The beneficial effects of adopting the above-mentioned further solution are as follows: When the spray bar is retracted, the spray bar moves downward and is retracted with the vertical plate as a guide until the base and connecting seat support the spray bar. Under the action of the spray bar's own weight, the base assembly is subjected to force and rotates adaptively with the rotating shaft assembly as the central axis, so that the base assembly provides surface contact support for the spray bar, ensuring that the spray bar is supported stably. This improves the existing technical problem that the existing spray bar is in a line contact state when retracted to the spray bar fixing seat, which leads to unstable spray bar retraction.

[0012] Furthermore, a first limiting groove is provided on the side of the vertical plate near the base assembly, and the other end of the connecting seat extends into the first limiting groove. The upper side of the connecting seat forms an upper rotation space with the upper groove wall of the first limiting groove, and the lower side forms a lower rotation space with the lower groove wall of the first limiting groove.

[0013] The beneficial effect of adopting the above-mentioned further solution is that when the connecting seat is subjected to the gravity of the spray bar and rotates adaptively with the rotating shaft assembly as the central axis, the other end of the connecting seat rotates in the first limiting groove, causing the groove wall of the first limiting groove to limit the rotation of the connecting seat. When the spray bar is tilted at a small angle, the connecting seat will rotate and maintain surface contact with the spray bar under the action of the gravity of the spray bar.

[0014] Furthermore, the base assembly is fixed with a second limiting plate, and the vertical rod assembly has a second limiting groove for the second limiting plate to extend into and rotate. The inner wall of the second limiting groove is used to limit the rotation of the second limiting plate.

[0015] The beneficial effect of adopting the above-mentioned further solution is that when the base assembly is subjected to force and rotates adaptively with the rotating shaft assembly as the central axis, the second limiting plate rotates in the second limiting groove. When the second limiting plate rotates to the extreme position, the inner wall of the groove of the second limiting groove limits the rotation of the second limiting plate, thereby restricting the base assembly from rotating adaptively within a very small angle range and ensuring that the base assembly provides stable support for the spray bar.

[0016] Furthermore, the rotating shaft assembly includes a bushing rotatably connected to the vertical rod assembly at its middle end, two sleeves respectively fitted onto both ends of the bushing, and two limiting bolts respectively passing through the two sleeves. Both sleeves are fixedly connected to the base assembly, and both limiting bolts are simultaneously connected to the bushing.

[0017] The beneficial effect of adopting the above-mentioned further solution is that when the base assembly rotates adaptively due to the gravity of the spray bar, the base assembly, bushing, and two sleeves rotate simultaneously relative to the vertical rod assembly with the bushing as the central axis.

[0018] Furthermore, the rotating shaft assembly also includes a fixed sleeve that is sleeved on and rotatably connected to the bushing, and the fixed sleeve is fixedly connected to the vertical rod assembly.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the fixed sleeve forms a rotational support for the bushing, so as to ensure that the bushing rotates smoothly and stably relative to the vertical rod assembly.

[0020] Furthermore, the side wall of the fixing sleeve is provided with an oil hole, and the oil hole is connected to an oil nozzle.

[0021] The beneficial effect of adopting the above-mentioned further solution is that it allows for lubrication of the rotating surfaces between the fixed sleeve and the bushing by adding grease through the grease fitting, thereby reducing friction during angle adjustment.

[0022] Furthermore, the vertical rod assembly and / or the base assembly are used to support a flexible plate connected to one side of the spray bar.

[0023] The beneficial effects of adopting the above-mentioned further solution are: by forming an elastic support for the spray bar through the flexible plate, a planar support structure for the spray bar is formed, while the impact of mechanical vibration transmission on the spray bar is reduced through the flexible plate.

[0024] On the other hand, this utility model provides a sprayer, including the aforementioned adaptive balance spray bar holder. Attached Figure Description

[0037] 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.

[0038] On the one hand, this utility model provides an adaptive balance spray bar fixing seat, as described below.

[0039] Example 1

[0040] like Figures 1 to 6 An adaptive balance spray bar mounting base includes a vertically inclined vertical rod assembly 1, a horizontally arranged base assembly 2, and a rotating shaft assembly 3 fixedly connected to one end of the base assembly 2. The rotating shaft assembly 3 is rotatably connected to the lower end of the vertical rod assembly 1.

[0041] The beneficial effects of this embodiment are as follows: When the spray bar is retracted, the spray bar moves downward and is retracted with the vertical rod assembly 1 as the guide. When the spray bar comes into contact with the base assembly 2, the base assembly 2 is subjected to force under the action of the spray bar's own weight and rotates adaptively with the rotating shaft assembly 3 as the central axis. This allows the base assembly 2 to provide surface contact support for the spray bar, ensuring that the spray bar is supported stably. This improves the existing technical problem that the existing spray bar is in a line contact state when it is retracted to the spray bar fixing seat, which leads to unstable spray bar retraction.

[0042] Based on the above embodiment, the vertical rod assembly 1 is a hollow rod-shaped structure to reduce weight and fuel consumption. Multiple nuts 113 are welded to the inner bottom of the vertical rod assembly 1, and each nut is threadedly connected to a screw 114, so that the vertical rod assembly 1 is fixedly installed by means of the screw 114 being threadedly connected to the nut 113.

[0043] Example 2

[0044] like Figures 5 to 10 Based on embodiment 1, the vertical rod assembly 1 includes at least two spaced-apart first limiting plates 12, and the base assembly 2 includes a connecting seat 22, which has a downward opening structure and forms an installation groove 221. The upper end of each first limiting plate 12 extends into the installation groove 221. The rotating shaft assembly 3 is installed in the installation groove 221, and its middle end is rotatably connected to the upper end of each first limiting plate 12. Both ends of the shaft are fixedly connected to the connecting seat 22.

[0045] The beneficial effect of adopting the preferred solution in the above embodiments is that when the base assembly 2 is subjected to force and rotates adaptively with the rotating shaft assembly 3 as the central axis, the connecting seat 22 rotates simultaneously with the rotating shaft assembly 3 as the central axis relative to each of the first limiting plates 12, so that the upper ends of each of the first limiting plates 12 in the radial direction of the rotating shaft assembly 3 can contact the bottom of the mounting groove 221. That is, each of the first limiting plates 12 limits the rotation of the connecting seat 22 (this limit is the first limit), so as to control the angle of adaptive rotation of the base assembly 2 and the spray bar supported by it, ensuring stable support after the spray bar is retracted, and controlling the adaptive rotation of the spray bar within a small angle.

[0046] At the same time, at least two spaced No. 1 limit plates 12 support the rotating shaft assembly 3 simultaneously, which can ensure the support stability of the rotating shaft assembly 3, thereby ensuring the support stability of the spray bar by the cantilever structure formed by the base assembly 2 relative to the vertical rod assembly 1.

[0047] Based on the above embodiments, such as Figure 8 Along the width direction of the connecting seat 22 (i.e., the horizontal extension direction perpendicular to the length direction of the base assembly 2), both ends of the upper side of the first limiting plate 12 are downwardly inclined slope structures, forming a slope 122. The inclination angle of the slope 122 relative to the horizontal plane is 1°-10°. When the connecting seat 22 rotates simultaneously with each first limiting plate 12 about the central axis of the rotating shaft assembly 3, the slope 122 rotates towards the bottom of the mounting groove 221, and the downwardly inclined slope 122 can relatively increase the rotatable angle of the connecting seat 22.

[0048] like Figure 9 and Figure 10 An observation hole 223 with at least one through-hole for communicating with the mounting groove 221 is provided on the upper side of the connector 22 to reduce the weight of the connector 22 and reduce mechanical energy consumption.

[0049] As a specific embodiment of the above, each of the first limiting plates 12 is arranged at intervals along the length direction of the base assembly 2.

[0050] Example 3

[0051] like Figure 9 and Figure 10 Based on embodiments 1 and 2, the vertical rod assembly 1 further includes a vertically inclined vertical plate 11, and the lower end of each first limiting plate 12 is fixedly connected to the lower end of the vertical plate 11; the base assembly 2 further includes a base 21, and one end of the connecting seat 22 is detachably connected to one end of the base 21.

[0052] The beneficial effect of the preferred solution in the above embodiments is that when the spray bar is retracted, the spray bar moves downward and is retracted with the vertical plate 11 as the guide. The base 21 and the connecting seat 22 support the spray bar at the same time. Under the action of the spray bar's own weight, the base assembly 2 is subjected to force and rotates adaptively with the rotating shaft assembly 3 as the central axis, so that the base assembly 2 provides surface contact support for the spray bar, ensuring that the spray bar is supported stably. This improves the existing technical problem that the existing spray bar is in a line contact state when it is retracted to the spray bar fixing seat, resulting in unstable spray bar retraction.

[0053] Based on the above embodiment, multiple nuts 113 are welded to the bottom inner side of the vertical plate 11, and each screw 114 is connected to the bottom of the vertical plate 11 to realize the installation of the vertical plate 11.

[0054] A bent plate 23 is fixed at one end of the connecting seat 22 and the base 21 that abuts against each other. The two bent plates 23 abut against each other and can be welded together at the same time.

[0055] As a parallel arrangement, both curved plates 23 are simultaneously equipped with connecting bolts 24. The connecting bolts 24 are fitted with washers, and the rods are threaded with nuts to achieve a detachable connection between the connecting seat 22 and the base 21.

[0056] As a parallel solution, the two bent plates 23 can also be detachably connected by means of plugging, snapping, etc.

[0057] A nylon plate is also fixedly connected to the curved plate 23 on the side of the connecting seat 22 near the vertical plate 11 to achieve surface contact with the spray bar.

[0058] Example 4

[0059] like Figure 6 , Figure 9 as well as Figure 10 Based on embodiments 1-3, a first limiting groove 111 is provided on the side of the vertical plate 11 near the base assembly 2, and the other end of the connecting seat 22 extends into the first limiting groove 111. The upper side of the connecting seat 22 forms an upper rotation space with the upper groove wall of the first limiting groove 111, and the lower side forms a lower rotation space with the lower groove wall of the first limiting groove 111.

[0060] The beneficial effect of adopting the preferred solution in the above embodiments is that when the connecting seat 22 is subjected to the gravity of the spray bar and rotates adaptively about the central axis of the rotating shaft assembly 3, the other end of the connecting seat 22 rotates in the first limiting groove 111, causing the groove wall of the first limiting groove 111 to limit the rotation of the connecting seat 22 (this limiting is the second limiting). When the spray bar is tilted at a small angle, the connecting seat 22 will rotate and maintain surface contact with the spray bar under the action of the gravity of the spray bar.

[0061] Meanwhile, by extending the other end of the connecting seat 22 into the first limiting groove 111, the length of the cantilever structure formed by the base assembly 2 relative to the vertical rod assembly 1 is shortened, thereby reducing the width of the entire sprayer and facilitating road transportation.

[0062] Based on the above embodiments, the lower end of each No. 1 limiting plate 12 is fixedly connected to the lower groove wall of the No. 1 limiting groove 111.

[0063] Example 5

[0064] like Figure 9 and Figure 10 Based on embodiments 1-4, the base assembly 2 is fixed with a second limiting plate 222, and the vertical rod assembly 1 is provided with a second limiting groove 121 for the second limiting plate 222 to extend into and rotate. The inner wall of the groove of the second limiting groove 121 is used to limit the rotation of the second limiting plate 222.

[0065] The beneficial effect of adopting the preferred solution in the above embodiments is that when the base assembly 2 is subjected to force and rotates adaptively with the rotating shaft assembly 3 as the central axis, the second limiting plate 222 rotates in the second limiting groove 121, and when the second limiting plate 222 rotates to the limit position, the inner wall of the groove of the second limiting groove 121 limits the rotation of the second limiting plate 222 (this limit is the third limit), so as to restrict the base assembly 2 from rotating adaptively within a very small angle range and ensure that the base assembly 2 provides stable support for the spray bar.

[0066] As a specific embodiment of the above, when the base assembly 2 is in a horizontal state, the second limiting plate 222 extending into the second limiting groove 121 faces the bottom of the second limiting groove 121; when the base assembly 2 rotates relative to the vertical rod assembly 1, the second limiting plate 222 rotates from the bottom of the second limiting groove 121 toward the inner wall of the opening of the second limiting groove 121, until the inner wall at the opening of the second limiting groove 121 limits the rotation of the second limiting plate 222.

[0067] When the second limiting plate 222 is damaged, or the inner wall at the opening of the second limiting groove 121 cannot limit the rotation of the second limiting plate 222, when the second limiting plate 222 rotates out of the second limiting groove 121, each first limiting plate 12 can abut against the bottom of the mounting groove 221 (that is, the first limiting plate 12 abuts against the connecting seat 22), forming the first limit.

[0068] Based on the above embodiment, both inclined surfaces 122 are connected to the opening of the second limiting groove 121.

[0069] The observation hole 223 is opened towards the second limiting groove 121 so as to observe the second limiting plate 222 extending into the second limiting groove 121.

[0070] Example 6

[0071] like Figures 6 to 10 Based on embodiments 1-5, the rotating shaft assembly 3 includes a bushing 31 rotatably connected to the vertical rod assembly 1 at its middle end, two sleeves 32 respectively sleeved at both ends of the bushing 31, and two limiting bolts 33 respectively passing through the two sleeves 32. Both sleeves 32 are fixedly connected to the base assembly 2, and both limiting bolts 33 are simultaneously connected to the bushing 31.

[0072] The beneficial effect of adopting the preferred solution in the above embodiments is that when the base assembly 2 rotates adaptively due to the gravity of the spray bar, the base assembly 2, the bushing 31, and the two sleeves 32 simultaneously rotate relative to the vertical rod assembly 1 with the axis of the bushing 31 as the central axis.

[0073] Based on the above embodiment, one sleeve 32 is fixedly connected to the base 21 and the sleeve 32 passes through one end of the connecting seat 22; the other sleeve 32 is fixedly connected to or passes through the other end of the connecting seat 22.

[0074] Based on the above embodiment, another sleeve 32 is in the shape of a stepped shaft, with its small diameter end passing through the other end of the connecting seat 22, and its large diameter end shoulder abutting against the connecting seat 22 to form an installation limit for the other sleeve 32.

[0075] During installation, first insert another sleeve 32 through the other end of the connecting seat 22; then insert the other end of the connecting seat 22 into the first limiting groove 111, and let the first limiting plate 12 extend into the mounting groove 221; then insert the bushing 31, and connect the other sleeve 32 and the bushing 31 to limit the position using one of the limiting bolts 33; then insert one of the sleeves 32 fixedly connected to the base 21 into the bushing 31, and connect one of the sleeves 32 and the bushing 31 to limit the position using another limiting bolt 33; finally, fix the connecting seat 22 and the base 21 together.

[0076] Example 7

[0077] like Figures 5 to 7 Based on embodiments 1-6, the rotating shaft assembly 3 further includes a fixed sleeve 34 that is sleeved and rotatably connected to the bushing 31, and the fixed sleeve 34 is fixedly connected to the vertical rod assembly 1.

[0078] The beneficial effect of adopting the preferred solution in the above embodiments is that the fixed sleeve 34 forms a rotational support for the bushing 31, so as to ensure that the bushing 31 rotates smoothly and stably relative to the vertical rod assembly 1.

[0079] Based on the above embodiment, the two sleeves 32 respectively abut against the two ends of the fixed sleeve 34. And the fixed sleeve 34 is also fixedly connected to each of the first limiting plates 12.

[0080] Example 8

[0081] like Figures 5 to 7 Based on embodiments 1-7, the side wall of the fixing sleeve 34 is provided with an oil hole, and the oil hole is connected to an oil nozzle 4.

[0082] The advantage of adopting the preferred solution in the above embodiments is that it allows for lubrication of the rotating surface between the fixed sleeve 34 and the bushing 31 by adding grease through the grease nipple 4, thereby reducing friction during angle adjustment.

[0083] Example 9

[0084] like Figure 1 and Figure 2Based on embodiments 1-8, the vertical rod assembly 1 and / or the base assembly 2 are used to support a flexible plate 5 connected to one side of the spray bar.

[0085] The beneficial effect of adopting the preferred solution in the above embodiments is that, while forming a planar support structure for the spray bar by using the flexible plate 5 to provide elastic support for the spray bar, the flexible plate 5 also reduces the impact of mechanical vibration transmission on the spray bar.

[0086] The flexible plate 5 can be made of nylon and can be installed and fixed by bolts.

[0087] Specifically, at least two flexible plates 5 are provided on both the base 21 and the connecting seat 22; and multiple flexible plates 5 are fixed on the side of the vertical plate 11 near the base 21.

[0088] On the other hand, this utility model provides a sprayer, as detailed below.

[0089] Example 10

[0090] A sprayer includes an adaptive balancing spray boom mounting base as described in Examples 1-9, a chassis, and a spray boom. A vertical plate 11 is fixedly connected to the chassis by a screw 114, and the spray boom is slidably mounted on the vertical plate 11. When retracting, the spray boom slides and retracts along the vertical plate 11 until its bottom abuts against the base 21 and the connecting seat 22. Under the weight of the spray boom, the connecting seat 22 rotates adaptively about the fixing sleeve 34 as its central axis, so that the spray boom and the flexible plate 5 on the base assembly 2 are in a line contact support state, ensuring support stability.
