DETAILED DESCRIPTION

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0026] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0028] In one embodiment, see Figure 1 and Figure 2 , a spraying machine for gardening and tree maintenance is provided, comprising a frame base 11, a paint rack 12 arranged on the frame base 11, and a paint kettle 13 installed on the paint rack 12;

[0029] The output end of the coating kettle 13 is provided with a flow divider pump 14, the output end of the flow divider pump 14 is divided into a plurality of flow divider pipe groups 15, the output end of the flow divider pipe group 15 is externally connected to a turnover pipe group 16 and a spray assembly 17 installed on the pipe end of the turnover pipe group 16;

[0030] The frame base 11 is also provided with a front frame base 21 and a front support bar 22 mounted on the front frame base 21, a spray base 23 is provided on the front support bar 22, a support bracket 24 is installed at the outer end of the spray base 23, and the spray assembly 17 is mounted on the support bracket 24;

[0031] The spraying base 23 is provided with a pushing assembly 25, and the support bracket 24 is slidably installed on the pushing assembly 25. A lifting bracket 26 is provided on the plate surface of the front support bar 22, and the spraying base 23 is installed on the lifting bracket 26. A lifting drive member 27 is provided on the side edge of the front support bar 22, and the lifting drive member 27 drives the spraying base 23 to move along the lifting bracket 26.

[0032] The frame base 11 is made of durable metal material, with good load-bearing capacity and stability, ensuring the stability of the entire sprayer during movement. The paint rack 12 is fixed on the frame base 11 to support and fix the paint kettle 13. The bottom of the paint kettle 13 is equipped with a stirring device to ensure that the paint remains uniform during storage and avoids precipitation. The diverter pump 14 is the core component of paint delivery, and its output end is divided into several diverter pipe groups 15 through a precisely designed diverter device. Each diverter pipe group 15 can independently control the flow rate to meet the spraying needs of different trees. The turnover pipe group 16 is a bridge connecting the diverter pipe group 15 and the spraying assembly 17. It is made of flexible material, which is convenient for flexible arrangement and adapting to complex and changeable working environments. The spraying assembly 17 is provided with a nozzle and a regulating valve, which can accurately control the spraying pressure and range to ensure that the paint is evenly covered on the surface of the tree. The support frame 24 is designed with a slide rail and a locking mechanism, so that the spraying assembly 17 can be freely adjusted in the horizontal direction, which is convenient for accurate spraying of different parts of the tree. The front support rail 22 and the front frame base 21 form a stable support frame, providing reliable support for the spray base 23 and all the components thereon. The push assembly 25 adopts an electric or pneumatic push rod, and by controlling the extension and retraction of the push rod, the support bracket 24 and the spray assembly 17 can be quickly moved in the horizontal direction, which is convenient for adjusting the spray position. The lifting bracket 26 is made of high-strength steel to ensure stability during the lifting process. The lifting drive 27 is used to realize the smooth lifting and lowering of the spray base 23 and its load in the vertical direction to meet the spraying requirements of different heights.

[0033] This embodiment realizes the rapid and uniform distribution of paint through the design of the diverter pump 14 and multiple diverter tube groups 15, and greatly improves the flexibility and efficiency of the spraying operation by combining the movable spraying components and the lifting system. The precise control and flexible adjustment capabilities of the spraying components ensure that the paint can evenly cover the surface of the tree, reduce waste, and improve the maintenance effect. The electric or pneumatically driven lifting and pushing system, as well as the easy-to-operate control system, enable operators to quickly get started, reduce the difficulty of operation, and improve work safety.

[0034] In one embodiment, see Figure 1 , Figure 2 and Figure 4 This embodiment is a further design of the above embodiment. On this basis, the specific implementation structure of the spraying base 23 and the support bracket 24 is designed as follows:

[0035] The main body of the spray base 23 is a spray substrate 31, and the tail end of the spray substrate 31 is provided with a rear plate frame 32 and a turnover box 33 installed on the rear plate frame 32, and the rear side of the turnover box 33 is provided with a plurality of secondary output valves 34, and the top of the turnover box 33 is provided with a plurality of turnover joints 35; the diversion pipe group 15 is connected to the turnover box 33 through the secondary output valve 34, and the input end of the turnover pipe group 16 is connected to the corresponding turnover joint 35.

[0036] The spraying substrate 31 constitutes a plate as a support platform for the entire spraying system, and a turnover box 33 is installed on the rear plate frame 32, which is an intermediate storage and distribution device. The design of the turnover box 33 takes into account the storage and distribution of paint, and a number of secondary output valves 34 are set on the rear side of the box. These output valves can accurately control the flow of paint, ensure that the paint enters the turnover box 33 smoothly from the diversion pipe group 15, and adjust the output to different spraying components 17 as needed. The setting of the secondary output valve 34 not only improves the distribution efficiency of the paint, but also enhances the flexibility and controllability of the system. Several turnover joints 35 are configured on the top of the box body of the turnover box 33. These joints serve as the input end of the turnover pipe group 16 to achieve smooth transmission of paint from the turnover box 33 to the spraying component 17. The design of the turnover joint 35 takes into account the needs of quick connection and disconnection, which is convenient for replacing the paint or maintaining the system as needed during the operation. In this way, the diverter pipe set 15 is connected to the turnover box 33 through the secondary output valve 34, and the input end of the turnover pipe set 16 is connected to the corresponding turnover joint 35, forming a complete and efficient paint transmission and distribution system. This design not only improves the utilization rate of the paint, but also ensures the stability and continuity of the spraying operation.

[0037] The support frame 24 includes a support base plate 41 and a support main plate 42 arranged on the support base plate 41, and a rear support plate 44 and a front support plate 43 are arranged on the support main plate 42. The spray assembly 17 includes a plurality of spray gun barrels 45 and a coating nozzle 46 installed on the barrel end of the spray gun barrel 45. The support base plate 41 serves as the installation base of the entire support frame 24, and a rear support plate 44 and a front support plate 43 are arranged on the support main plate 42. These two components together provide reliable support for the spray assembly 17. The rear support plate 44 is located at the rear of the support main plate 42, and is mainly used to support and fix the rear of the spray gun barrel 45 to ensure that it will not shake or fall off during operation. The front support plate 43 is located at the front of the support main plate 42, and cooperates with the rear support plate 44 to jointly realize the comprehensive support of the spray assembly 17. The spray gun barrel 45 serves as a conveying channel for the paint, and its design takes into account the flow and pressure requirements of the paint to ensure that the paint can be output evenly and stably. The coating nozzle 46 is installed at the barrel end of the spray gun barrel 45 and is used to spray the coating evenly on the surface of the tree.

[0038] Several barrel fixing blocks 47 are installed on the support main board 42, and the spray gun barrel 45 is inserted and installed in the corresponding barrel fixing blocks 47; several barrel mounting sleeves 48 are also provided on the rear support plate 44, and the barrel body of the barrel fixing block 47 is inserted into the barrel mounting sleeve 48 and connected to the pipeline of the corresponding turnover pipe group 16 through the diversion valve 49. In order to firmly install the spray gun barrel 45 on the support main board 42, several barrel fixing blocks 47 are installed on the support main board 42. These fixing blocks have slots matching the spray gun barrel 45, so that the spray gun barrel 45 can be inserted and installed in the corresponding barrel fixing blocks 47 to achieve stable fixation. Several barrel mounting sleeves 48 are also provided on the rear support plate 44. These mounting sleeves are used in conjunction with the barrel fixing blocks 47 to further enhance the stability of the spray gun barrel 45. The diversion valve 49, as a control component for the flow of paint, can accurately adjust the flow and pressure of the paint to ensure that the paint can enter the spray gun barrel 45 and spray out smoothly according to the predetermined requirements.

[0039] See also Figure 4 and Figure 5The spraying base 23 is not only a supporting platform for the spraying assembly 17, but also responsible for realizing its movement in the horizontal direction. The spraying base 23 includes a bottom plate slider 52 arranged on the surface of the spraying substrate 31, and a push slide rail 51 is arranged at the bottom of the supporting base plate 41. The push slide rail 51 is slidably mounted on the bottom plate slider 52. These slide rails match the bottom plate slider 52, so that the support bracket 24 can slide smoothly along the spraying substrate 31. The design of the push slide rail 51 takes into account the load capacity and sliding smoothness, ensuring that the support bracket 24 can move stably during the operation. The spraying base 23 also includes a driving wheel 53 installed on the surface of the spraying substrate 31 and a push transmission belt 54 arranged on the driving wheel 53. The driving wheel 53 is arranged on the side edge of the bottom plate slider 52. The bottom of the supporting base plate 41 is fixedly connected to the belt surface of the push transmission belt 54 through the clamping fixing sheet 56. The bottom of the spraying substrate 31 is provided with a push motor 55 for driving the driving wheel 53. The push transmission belt 54 is wound around the driving wheel 53 to form a continuous transmission path. The bottom of the supporting base plate 41 is fixedly connected to the belt surface of the push transmission belt 54 through the clamping fixing plate 56. In this way, when the driving wheel 53 rotates, the push transmission belt 54 will drive the supporting base plate 41 and the supporting bracket 24 and the spray assembly 17 thereon to move together.

[0040] In one embodiment, see Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 This embodiment is a further design of the above embodiment. On this basis, the specific implementation structure of the front support bar 22 and the lifting drive member 27 is designed as follows:

[0041] The main body of the front support fence 22 is the front fence main frame plate 61, which is the front support structure of the entire spraying system. It is not only required to have sufficient strength and stability, but also to have good anti-deformation ability to meet the needs of long-term operation in complex outdoor environments. The lifting bracket 26 includes lifting rails 62 arranged on both sides of the front fence main frame plate 61 and a lifting frame plate 63 installed between the lifting rails 62. Its design takes into account the load capacity and sliding smoothness to ensure that the lifting frame plate 63 can move smoothly on the track. The lifting frame plate 63 is installed between the lifting rails 62 to carry the spraying substrate 31 and the spraying components 17 thereon.

[0042] The lifting drive member 27 includes a driven top wheel 73, a driving bottom wheel 82 and a traction belt 74, wherein the traction belt 74 is connected between the driven top wheel 73 and the driving bottom wheel 82; both ends of the lifting frame plate 63 are connected to the belt body of the traction belt 74 through the traction seat 64. A top wheel support 71 and a top wheel support shaft 72 installed on the top wheel support 71 are provided at the top of the plate end of the front support rail 22, and the driven top wheel 73 is installed on the top wheel support shaft 72; a bottom wheel support 81 is provided at the bottom of the plate end of the front support rail 22, a synchronous shaft 83 is provided between the bottom wheel supports 81, the driving bottom wheel 82 is installed at both ends of the synchronous shaft 83, and a shaft mounting sleeve 84 is also provided on the synchronous shaft 83; a power motor 86 is provided on the other side of the plate body of the front support rail 22, a power wheel 85 is installed on the shaft mounting sleeve 84, and a driving transmission member 87 is provided at the driving end of the power motor 86, and a notch is provided on the plate body of the front support rail 22, and the driving transmission member 87 passes through the notch and is connected to the power wheel 85.

[0043] The traction belt 74 is connected between the driven top wheel 73 and the driving bottom wheel 82 to form a continuous transmission path. The two ends of the lifting frame plate 63 are connected to the belt body of the traction belt 74 through the traction seat 64. In this way, when the driving bottom wheel 82 rotates, the traction belt 74 will drive the lifting frame plate 63 and the spraying substrate 31 thereon to move up and down together.

[0044] The top wheel support 71 arranged at the top of the plate end of the front support fence 22 is made of high-strength alloy material. The bottom wheel support 81 at the bottom of the plate end of the front support fence 22 is also made of high-strength alloy material and is fixed on the plate body of the front support fence 22 through precision welding technology. The two ends of the synchronous shaft 83 and the driving bottom wheel 82 are connected to the synchronous shaft 83 through precision bearings to ensure stability and durability during rotation. The shaft mounting sleeve 84 is made of wear-resistant and corrosion-resistant materials, and its inner diameter is matched with the outer diameter of the synchronous shaft 83 through precision machining to reduce friction resistance during rotation. The power wheel 85 is installed on the shaft mounting sleeve 84 and connected to the shaft mounting sleeve 84 through precision bearings. In this way, when the power motor 86 drives the power wheel 85 to rotate by driving the transmission member 87, it can ensure the synchronous rotation of the synchronous shaft 83 and the driving bottom wheel 82, thereby realizing the smooth transmission of the traction belt 74. In addition, reinforcing ribs and support frames can also be set on the plate body of the front support fence 22 to enhance its overall rigidity and anti-deformation ability.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
