Description

Technical Field

[0001] This utility model relates to the field of spray device technology, specifically to a portable, mobile, ultra-low volume spray device. Background Technology

[0002] Ultra-low volume spraying devices are application equipment that uses special atomization technology to convert liquid pesticides into ultra-fine droplets with a diameter of 5-50 micrometers. Their core features are "low liquid pesticide usage and high droplet coverage". With the advantages of strong droplet suspension, wide diffusion range and high adhesion efficiency, they are widely used in public health, agricultural plant protection, environmental disinfection and other fields.

[0003] In existing technologies, spraying devices are needed to spray pesticides on specific areas to achieve the purposes of pest and disease control, disinfection, or plant maintenance. Ultra-low volume (ULV) spraying technology is advantageous because it produces fine atomized pesticide particles and covers a wide area. However, it currently has some drawbacks: traditional ULV spraying devices are generally large and heavy, and their movement relies heavily on bottom rollers. However, in complex environments with limited space, such as field paths and narrow corridors, the roller spacing of ULV spraying devices is usually too wide, making it difficult for the equipment to pass smoothly. This limits the portability and mobility of ULV spraying devices and affects their normal operation. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a portable mobile ultra-low volume spraying device, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a portable mobile ultra-low volume spraying device, including a spraying capacity shell and a handle set on the spraying capacity shell. A tightening cap is fixedly sleeved on one side of the upper end of the spraying capacity shell. A hose is fixedly installed on the lower side of one side of the spraying capacity shell. A spray gun head assembly is fixedly installed on the upper end of the hose. A base plate is fixedly installed on the lower end of the spraying capacity shell. An adjustable distance moving component is provided on the lower end of the base plate. The adjustable movement component includes a support rod, and a fixing block is fixedly installed on one side of the support rod near both ends. The fixing block is fixedly connected to both sides of the base plate near both ends.

[0006] Furthermore, a support block is fixedly connected to the other side of the support rod near the center, a track groove is provided at the bottom of the base plate, a crossbeam is fixedly connected to the inside of the track groove near the center, a bearing sleeve is fixedly fitted inside one of the support blocks, a double-acting screw is fixedly fitted inside the inner ring of the bearing sleeve, and a handle is fixedly installed at one end of the double-acting screw.

[0007] Furthermore, movable semicircular blocks are rotatably sleeved at both ends of the outer side of the bidirectional lead screw, and the upper ends of the movable semicircular blocks are respectively fixedly connected to a first support rod and a second support rod.

[0008] Furthermore, brackets are fixedly installed at both ends of the first and second support rods, a roller is rotatably sleeved at the lower end of the bracket, and a sliding block is fixedly installed at the upper end of the bracket.

[0009] Furthermore, the sliding block is slidably sleeved inside the track groove of the base plate, and a guide rod is slidably sleeved inside the sliding block.

[0010] Furthermore, one end of the guide rod is fixedly sleeved inside the crossbeam rod, and the other end of the guide rod is fixedly sleeved inside one side of the support rod near both ends.

[0011] The technical solution provided by this utility model has the following advantages compared with the known prior art: This invention utilizes an adjustable moving component to rotate a handle, which in turn rotates a bidirectional lead screw, causing two movable semicircular blocks to move closer together. This, in turn, causes the first support rod, the second support rod, and the two sets of brackets to move closer together, ultimately reducing the distance between the rollers. This allows the roller width to adapt to the width of passageways in various narrow scenarios, enabling ultra-low volume spraying equipment to pass smoothly in complex environments with limited space, such as field paths and narrow corridors. It effectively reduces the constraints on the portability and mobility of ultra-low volume spraying equipment caused by environmental limitations, and avoids preventing the ultra-low volume spraying equipment from failing to operate normally.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0016] The present invention will be further described below with reference to the embodiments. Example 1:

[0017] Reference Figures 1 to 4 This is the first embodiment of the present invention, disclosing a portable mobile ultra-low volume spraying device, including a spraying capacity housing 1 and a handle 2 disposed on the spraying capacity housing 1. A tightening cap 3 is fixedly fitted to one side of the upper end of the spraying capacity housing 1. A hose 4 is fixedly installed on the lower side of one side of the spraying capacity housing 1. A spray nozzle assembly 5 is fixedly installed at the upper end of the hose 4. A base plate 6 is fixedly installed at the lower end of the spraying capacity housing 1. An adjustable movement assembly 7 is provided at the lower end of the base plate 6. The spraying capacity housing 1 serves as a liquid storage container. The tightening cap 3 at the upper end is used to seal the liquid storage space and facilitates the operator to open and add liquid. When the device is started, it functions like a miniature pump. The system generates negative pressure or pressure to discharge the liquid medicine inside the spray volume housing 1 through the lower side hose 4. The liquid medicine is then transported along the hose 4 to the upper spray gun head assembly 5. The spray gun head assembly 5 has a built-in atomizing structure, such as a high-speed airflow nozzle or an ultrasonic vibration module, which atomizes the liquid medicine into ultra-low volume droplets of 10-50 microns. At the same time, by holding the spray gun head assembly 5, the spray direction and angle are controlled so that the droplets can evenly cover the target area to achieve the purpose of pest and disease control, disinfection and sterilization, or plant maintenance. The ultra-low volume spray device is an existing technology and will not be described in detail here. Common ultra-low volume spray device models include Dalian Huamu's HM-MD1 and HMWZB-5. The adjustable movement assembly 7 includes a support rod 71. Fixing blocks 61 are fixedly installed on one side of the support rod 71 near both ends. The fixing blocks 61 are fixedly connected to both sides of the base plate 6 near both ends. Four fixing blocks 61 are fixedly connected to the four opposite corners of the outer side of the base plate 6. A support block 72 is fixedly connected to the other side of the support rod 71 near the center. A track groove 62 is opened at the bottom of the base plate 6. A crossbeam rod 63 is fixedly connected to the center of the track groove 62. A bearing sleeve 73 is fixedly fitted inside one of the support blocks 72. A double-acting screw 711 is fixedly fitted inside the inner ring of the bearing sleeve 73. The outer side of one end of the double-acting screw 711 rotates simultaneously with the inner ring of the bearing sleeve 73, and the inner ring rotates inside the outer ring of the bearing sleeve 73. A handle 712 is fixedly installed on one end of the double-acting screw 711.

[0018] The outer sides of the double-acting screw 711 are rotatably fitted with movable semicircular blocks 79 at both ends. The upper ends of the movable semicircular blocks 79 are respectively fixedly connected to the first support rod 76 and the double-acting screw 711. The first support rod 76 and the second support rod 710 are both fixedly installed with brackets 74. The lower end of the bracket 74 is rotatably fitted with a roller 75. The upper end of the bracket 74 is fixedly installed with a sliding block 77. The sliding block 77 is slidably fitted inside the track groove 62 of the base plate 6.

[0019] When using the ultra-low volume spraying equipment, if it needs to be used in complex environments with limited space, such as field paths or narrow corridors, the operator drives the bidirectional lead screw 711 to rotate by turning the handle 712. Since the threads at both ends of the bidirectional lead screw 711 are opposite in direction, and movable semicircular blocks 79 are respectively rotatably sleeved at both ends on its outer side, the two movable semicircular blocks 79 will move relatively closer or further away along the lead screw during rotation. As the two movable semicircular blocks 79 move, the fixedly connected first support rod 76 and second support rod 710 will also move relatively closer or further away. This causes the two sets of supports 74 to move, while the sliding block 77 at the upper end of the support 74 slides in the track groove 62 of the base plate 6. At the same time, the crossbeam 63 limits the sliding of the sliding block 77, thereby adjusting the distance between the two sets of rollers 75. This allows for the adjustment of the width distance between the rollers 75 that move the ultra-low volume spraying equipment, making it adaptable to complex environments with limited space, such as different field paths and narrow corridors. This effectively prevents the ultra-low volume spraying equipment from being unable to move smoothly, thereby reducing restrictions on the portability and mobility of the ultra-low volume spraying equipment and avoiding any impact on its normal operation. Example 2:

[0020] Reference Figure 3 and Figure 4This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a guide rod 78 is slidably sleeved inside the sliding block 77. One end of the guide rod 78 is fixedly sleeved inside the crossbeam rod 63, and the other end of the guide rod 78 is fixedly sleeved inside one side of the support rod 71 near both ends.

[0021] In use, the sliding block 77 can slide along the guide rod 78. One end of the guide rod 78 is fixed inside the crossbeam rod 63, and the other end is fixed on one side of the support rod 71 near both ends. This structure provides a stable guiding effect for the movement of the sliding block 77, roller 75, bracket 74, and other structures. When the sliding block 77 needs to move, its movement trajectory is restricted by the guide rod 78, and it can only slide along the axial direction of the guide rod 78. Since the two ends of the guide rod 78 are fixedly connected to the crossbeam rod 63 and the support rod 71 respectively, the position of the guide rod 78 itself remains stable, thereby ensuring that the sliding block 77 will not deviate or shake during the sliding process.

[0022] The remaining structure is the same as that in Example 1.

[0023] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
