Description

Technical Field

[0001] The present invention relates to the technical field of sprayers, and in particular to an adaptive balanced spray boom fixing seat and a sprayer. Background Art

[0002] In order to improve the working efficiency, large-scale boom sprayers generally have a large spray width. The spray parts are installed on the boom and extend to both ends of the boom along the length direction. The boom is supported on the boom fixing seat, and the boom fixing seat is fixed on the chassis. Due to the long boom cantilever, the bumpy field during operation, and mechanical vibration, the boom will tilt at a small angle (generally less than 5°) during the expansion and contraction process. Therefore, when the boom is retracted to the boom fixing seat, the boom tilted at a small angle is in line contact with the boom fixing seat, causing the boom to be unstable when retracted. Summary of the invention

[0003] Aiming at the technical problem that the existing spray boom is in a linear contact state when being recovered on a spray boom fixing seat, resulting in unstable recovery of the spray boom, the present invention provides an adaptive balanced spray boom fixing seat and a sprayer.

[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 an adaptive balanced spray boom fixing seat, including a vertically inclined vertical rod assembly, a laterally 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 effect of the present invention is that when the spray boom is recovered, the spray boom is moved downward and recovered with the vertical rod assembly as the guide. When the spray boom abuts against the base assembly downward, the base assembly is subjected to force under the action of the spray boom's own gravity and adaptively rotates with the rotating shaft assembly as the central axis, so that the base assembly supports the spray boom in a surface contact manner, ensuring that the spray boom is supported stably, thereby improving the existing technical problem that the spray boom is in a line contact state when it is recovered to the spray boom fixing seat, resulting in unstable spray boom recovery.

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

[0008] Furthermore, the vertical rod assembly includes at least two spaced-apart No. 1 limit plates, and the base assembly includes a connecting seat, which has a lower opening structure and forms a mounting groove, and the upper end of each No. 1 limit plate extends into the mounting groove; the rotating shaft assembly is installed in the mounting groove, and its middle end is simultaneously rotatably connected to the upper end of each No. 1 limit plate, and its two ends are fixedly connected to the connecting seat.

[0009] The beneficial effect of adopting the above further scheme is that when the base assembly is subjected to force and adaptively rotates with the rotating shaft assembly as the central axis, the connecting seat simultaneously rotates with the rotating shaft assembly as the central axis relative to each No. 1 limit plate, so that the upper ends of each No. 1 limit plate along the radial direction of the rotating shaft assembly can contact the bottom of the installation groove, that is, each No. 1 limit plate limits the rotation of the connecting seat to control the angle of adaptive rotation of the base assembly and the spray boom supported by it, ensure stable support of the spray boom after being recovered, and control the adaptive rotation of the spray boom within a smaller angle.

[0010] Furthermore, the vertical rod assembly also includes a vertically inclined vertical plate, and the lower end of each of the No. 1 limit 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 effect of adopting the above further scheme is that when the spray boom is recovered, the spray boom is moved downward and recovered with the vertical plate as the guide, until the base and the connecting seat support the spray boom at the same time. Under the action of the spray boom's own gravity, the base assembly is subjected to force and adaptively rotates with the rotating shaft assembly as the central axis, so that the base assembly supports the spray boom in surface contact, ensuring that the spray boom is supported stably, thereby improving the existing technical problem that the spray boom is in a line contact state when it is recovered to the spray boom fixing seat, resulting in unstable spray boom recovery.

[0012] Furthermore, a No. 1 limit groove is opened on one side of the vertical plate close to the base assembly, and the other end of the connecting seat extends into the No. 1 limit groove. The upper side of the connecting seat and the upper groove wall of the No. 1 limit groove form an upper rotation space, and the lower side and the lower groove wall of the No. 1 limit groove form a lower rotation space.

[0013] The beneficial effect of adopting the above further scheme is that when the connecting seat is subjected to the gravity of the spray boom and adaptively rotates with the rotating shaft assembly as the central axis, the other end of the connecting seat rotates in the No. 1 limiting groove, so that the groove wall of the No. 1 limiting groove limits the rotation of the connecting seat. When the spray boom is tilted at a small angle, the connecting seat will rotate under the action of the gravity of the spray boom and maintain surface contact with the spray boom.

[0014] Furthermore, the base assembly is fixed with a No. 2 limit plate, and the vertical rod assembly is provided with a No. 2 limit slot for the No. 2 limit plate to extend into and rotate, and the inner wall of the slot of the No. 2 limit slot is used to limit the rotation of the No. 2 limit plate.

[0015] The beneficial effect of adopting the above further scheme is that when the base assembly is subjected to force and adaptively rotates with the rotating shaft assembly as the central axis, the No. 2 limit plate rotates in the No. 2 limit groove, and when the No. 2 limit plate rotates to the extreme position, the inner wall of the groove of the No. 2 limit groove limits the rotation of the No. 2 limit plate, so as to limit the adaptive rotation of the base assembly within a very small angle range, thereby ensuring that the base assembly provides stable support for the spray boom.

[0016] Furthermore, the rotating shaft assembly includes a shaft sleeve whose middle end is rotatably connected to the vertical rod assembly, two sleeves respectively sleeved on both ends of the shaft sleeve, and two limiting bolts respectively passed through the two sleeves, the two sleeves are fixedly connected to the base assembly, and the two limiting bolts are simultaneously connected to the shaft sleeve.

[0017] The beneficial effect of adopting the above further solution is that when the base assembly is adaptively rotated by the gravity of the spray rod, the base assembly, the shaft sleeve and the two sleeves simultaneously rotate relative to the vertical rod assembly with the shaft sleeve as the central axis.

[0018] Furthermore, the rotating shaft assembly also includes a fixing sleeve which is sleeved and rotatably connected to the shaft sleeve, and the fixing sleeve is fixedly connected to the vertical rod assembly.

[0019] The beneficial effect of adopting the above further solution is that the fixing sleeve forms a rotation support for the shaft sleeve to ensure smooth and stable rotation of the shaft sleeve relative to the vertical rod assembly.

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

[0021] The beneficial effect of adopting the above further solution is that grease can be added through the grease nozzle to lubricate the rotating curved surface between the fixed sleeve and the shaft sleeve, thereby reducing the friction of angle adjustment.

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

[0023] The beneficial effect of adopting the above further solution is: by forming an elastic support effect on the spray rod through the flexible plate, forming a planar support structure for the spray rod, and at the same time reducing the impact of mechanical vibration transmission on the spray rod through the flexible plate.

[0024] On the other hand, the present invention provides a sprayer, comprising the adaptive balancing spray boom fixing seat. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] 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.

[0038] In one aspect, the present invention provides an adaptive balancing spray boom fixing seat, as described in detail below.

[0039] Example 1

[0040] like Figures 1 to 6An adaptive balanced spray boom fixing seat 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, and the rotating shaft assembly 3 is rotatably connected to the lower end of the vertical rod assembly 1.

[0041] The beneficial effect of this embodiment is that when the spray boom is recovered, the spray boom moves downward and is recovered guided by the vertical rod assembly 1. When the spray boom downwardly abuts against the base assembly 2, the base assembly 2 is subjected to force and adaptively rotates with the rotating shaft assembly 3 as the central axis under the action of the spray boom's own gravity, so that the base assembly 2 supports the spray boom in a surface contact manner, ensuring that the spray boom is supported stably, thereby improving the existing technical problem that the spray boom is in a line contact state when it is recovered to the spray boom fixing seat, resulting in unstable spray boom recovery.

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

[0043] Example 2

[0044] like Figures 5 to 10 On the basis of Example 1, the vertical rod assembly 1 includes at least two spaced-apart No. 1 limit plates 12, and the base assembly 2 includes a connecting seat 22, the connecting seat 22 is a lower opening structure and forms a mounting groove 221, and the upper end of each No. 1 limit plate 12 extends into the mounting groove 221; the rotating shaft assembly 3 is installed in the mounting groove 221, and its middle end is simultaneously rotatably connected to the upper end of each No. 1 limit plate 12, and its two ends are fixedly connected to the connecting seat 22.

[0045] The beneficial effect of adopting the preferred scheme in the above embodiment is that when the base assembly 2 is subjected to force and adaptively rotates with the rotating shaft assembly 3 as the center axis, the connecting seat 22 rotates simultaneously with the rotating shaft assembly 3 as the center axis relative to each No. 1 limit plate 12, so that the upper ends of each No. 1 limit plate 12 along the radial direction of the rotating shaft assembly 3 can contact the bottom of the mounting groove 221, that is, each No. 1 limit plate 12 forms a limit on the rotation of the connecting seat 22 (the limit is the first limit), so as to control the angle of adaptive rotation of the base assembly 2 and the spray boom supported by it, ensure stable support of the spray boom after being recovered, and control the adaptive rotation of the spray boom within a smaller angle.

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

[0047] Based on the above embodiments, Figure 8 , along the width direction of the connection 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 No. 1 limit plate 12 are inclined downwardly, forming an inclined surface 122, and the inclined surface 122 has an inclination angle of 1°-10° relative to the horizontal plane. When the connection seat 22 rotates relative to each No. 1 limit plate 12 at the same time with the rotating shaft assembly 3 as the central axis, on the contrary, the inclined surface 122 rotates toward the bottom of the installation groove 221, and the downwardly inclined inclined surface 122 can relatively expand the rotatable angle of the connection seat 22.

[0048] like Fig. 9 and Fig.10 At least one observation hole 223 communicating with the mounting groove 221 is provided through the upper side of the connecting seat 22 to reduce the weight of the connecting seat 22 and reduce mechanical energy consumption.

[0049] As a specific solution of the above embodiment, the No. 1 limiting plates 12 are arranged at intervals along the length direction of the base assembly 2 .

[0050] Example 3

[0051] like Fig. 9 and Fig.10 On the basis of embodiments 1 and 2, the vertical rod assembly 1 also includes a vertically inclined vertical plate 11, and the lower end of each No. 1 limit plate 12 is fixedly connected to the lower end of the vertical plate 11; the base assembly 2 also 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 adopting the preferred scheme in the above embodiment is that when the spray rod is recovered, the spray rod is moved downward and recovered with the vertical plate 11 as the guide, until the base 21 and the connecting seat 22 support the spray rod at the same time. Under the action of the spray rod's own gravity, the base assembly 2 is subjected to force and adaptively rotates with the rotating shaft assembly 3 as the central axis, so that the base assembly 2 supports the spray rod in a surface contact manner, ensuring that the spray rod is supported stably, thereby improving the existing technical problem that the spray rod is in a line contact state when it is recovered to the spray rod fixing seat, resulting in unstable recovery of the spray rod.

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

[0054] A bent plate 23 is fixed to one end where the connecting seat 22 and the base 21 abut 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 solution, the two bent plates 23 are simultaneously installed with connecting bolts 24 , the connecting bolts 24 are sleeved with washers, and the rods are threadedly connected 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 plugging, snapping, etc.

[0057] A nylon plate is also fixedly connected to one side of the bent plate 23 on the connecting seat 22 close to the vertical plate 11 to achieve surface contact abutment with the spray rod.

[0058] Example 4

[0059] like Figure 6 , Fig. 9 as well as Fig.10 On the basis of embodiments 1-3, a first limiting groove 111 is opened on one side of the vertical plate 11 close to 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 and the upper groove wall of the first limiting groove 111 form an upper rotation space, and the lower side and the lower groove wall of the first limiting groove 111 form a lower rotation space.

[0060] The beneficial effect of adopting the preferred scheme in the above embodiment is that when the connecting seat 22 is subjected to the gravity of the spray boom and adaptively rotates with the rotating shaft assembly 3 as the central axis, the other end of the connecting seat 22 rotates in the No. 1 limiting groove 111, so that the groove wall of the No. 1 limiting groove 111 limits the rotation of the connecting seat 22 (this limit is the second limit), and when the spray boom is tilted at a small angle, the connecting seat 22 will rotate under the action of the gravity of the spray boom to maintain surface contact with the spray boom.

[0061] At the same time, 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, so that the width of the entire sprayer is reduced, which is convenient for road transportation.

[0062] On the basis of the above-mentioned embodiment, 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 Fig. 9 and Fig.10 On the basis of 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, and 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 scheme in the above embodiment is that when the base assembly 2 is subjected to force and adaptively rotates with the rotating shaft assembly 3 as the central axis, the No. 2 limit plate 222 rotates in the No. 2 limit groove 121, and when the No. 2 limit plate 222 rotates to the extreme position, the inner wall of the groove of the No. 2 limit groove 121 limits the rotation of the No. 2 limit plate 222 (this limit is the third limit) to limit the adaptive rotation of the base assembly 2 within a very small angle range, thereby ensuring that the base assembly 2 provides stable support for the spray rod.

[0066] As a specific scheme of the above embodiment, when the base assembly 2 is in a horizontal state, the No. 2 limit plate 222 extending into the No. 2 limit groove 121 faces the bottom of the No. 2 limit groove 121; when the base assembly 2 rotates relative to the vertical rod assembly 1, the No. 2 limit plate 222 rotates from the bottom of the No. 2 limit groove 121 toward the inner wall of the slot opening of the No. 2 limit groove 121, and the inner wall at the slot opening of the No. 2 limit groove 121 limits the rotation of the No. 2 limit plate 222.

[0067] When the No. 2 limit plate 222 is damaged, or the inner wall at the slot of the No. 2 limit groove 121 cannot limit the rotation of the No. 2 limit plate 222, when the No. 2 limit plate 222 rotates out of the No. 2 limit groove 121, each No. 1 limit plate 12 can abut against the bottom of the installation slot 221 (that is, the No. 1 limit plate 12 abuts against the connecting seat 22), forming a first limit.

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

[0069] The observation hole 223 is opened toward 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 On the basis of embodiments 1-5, the rotating shaft assembly 3 includes a sleeve 31 whose middle end is rotatably connected to the vertical rod assembly 1, two sleeves 32 respectively sleeved at both ends of the sleeve 31, and two limit bolts 33 respectively penetrated through the two sleeves 32, the two sleeves 32 are fixedly connected to the base assembly 2, and the two limit bolts 33 are simultaneously connected to the sleeve 31.

[0072] The beneficial effect of adopting the preferred solution in the above embodiment is that when the base assembly 2 is adaptively rotated by the gravity of the spray rod, the base assembly 2, the sleeve 31 and the two sleeves 32 simultaneously rotate relative to the vertical rod assembly 1 with the axis of the sleeve 31 as the center axis.

[0073] Based on the above embodiment, one sleeve 32 is fixedly connected to the base 21 and penetrates one end of the connecting seat 22 ; the other sleeve 32 is fixedly connected or penetrates 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 pressed against the connecting seat 22 to form an installation limit for the other sleeve 32 .

[0075] During installation, first insert another sleeve 32 into the other end of the connecting seat 22; then insert the other end of the connecting seat 22 into the No. 1 limiting groove 111, and make the No. 1 limiting plate 12 extend into the installation groove 221; then, insert the shaft sleeve 31, and connect the other sleeve 32 and the shaft sleeve 31 for limiting by one of the limiting bolts 33; then, insert one of the sleeves 32 fixedly connected to the base 21 into the shaft sleeve 31, and connect one of the sleeves 32 and the shaft sleeve 31 for limiting by another limiting bolt 33; finally, fix the connecting seat 22 and the base 21.

[0076] Example 7

[0077] like Figures 5 to 7 On the basis of embodiments 1-6, the rotating shaft assembly 3 further includes a fixing sleeve 34 which is sleeved and rotatably connected to the shaft sleeve 31 , and the fixing sleeve 34 is fixedly connected to the vertical rod assembly 1 .

[0078] The beneficial effect of adopting the preferred solution in the above embodiment is that the fixing sleeve 34 forms a rotation support for the shaft sleeve 31 to ensure that the shaft sleeve 31 rotates smoothly and stably relative to the vertical rod assembly 1.

[0079] Based on the above embodiment, the two sleeves 32 are respectively abutted against the two ends of the fixing sleeve 34 , and the fixing sleeve 34 is fixedly connected to each of the first limiting plates 12 .

[0080] Example 8

[0081] like Figures 5 to 7 On the basis of embodiments 1-7, an oil hole is formed through the side wall of the fixing sleeve 34, and the oil hole is connected to the oil nozzle 4.

[0082] The beneficial effect of adopting the preferred solution in the above embodiment is that by adding grease through the grease nozzle 4, the rotating curved surface between the fixed sleeve 34 and the shaft sleeve 31 is lubricated to reduce the friction of angle adjustment.

[0083] Example 9

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

[0085] The beneficial effect of adopting the preferred solution in the above embodiment is that the flexible plate 5 forms an elastic support for the spray rod, forming a planar support structure for the spray rod, while the flexible plate 5 reduces the impact of mechanical vibration transmission on the spray rod.

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

[0087] Specifically, at least two flexible boards 5 are disposed on the base 21 and the connecting base 22 ; and a plurality of flexible boards 5 are fixed on one side of the vertical board 11 close to the base 21 .

[0088] In another aspect, the present invention provides a sprayer, as described in detail below.

When retracting, the spray rod slides and retracts along the vertical plate 11 until the bottom of the spray rod abuts against the base 21 and the connecting seat 22. Under the gravity of the spray rod, the connecting seat 22 adaptively rotates with the fixing sleeve 34 as the central axis, so that the spray rod and the flexible plate 5 on the base assembly 2 are in a linear contact support state, thereby ensuring the support stability.
