Description

Technical Field

[0001] The utility model relates to the technical field of slope regreening, in particular to a relay-type spraying device. Background Art

[0002] Slope greening projects have garnered increasing attention in recent years. However, traditional manual planting methods are unsuitable for high slopes due to their high risks and costs. Consequently, sprayers, as a more efficient and safe seeding device, have gained widespread use in greening projects. However, common sprayers currently available often suffer from poor mixing performance and short seeding distances.

[0003] Spray seeding requires that seeds, fertilizers, substrates and other materials be mixed in a certain proportion, and the degree of mixing is required to be high. When the spray seeding machine has insufficient stirring capacity, the degree of material mixing cannot meet the spraying requirements, which may cause uneven spraying, or the material to settle and clog in the pipeline. In addition, the spraying distance of a general spray seeding machine is relatively short, usually within tens of meters. For large or long-distance spraying areas, the equipment needs to be frequently moved to complete the operation, which not only reduces work efficiency, but also may affect the quality of spraying due to factors such as vibration during the movement of the equipment. If materials are transported over long distances, the degree of material mixing will change during the transportation process, affecting the quality of spraying. Therefore, how to provide a spray seeding machine with strong mixing ability and multiple stirring capabilities, long pumping distance, and large spray coverage is an urgent problem to be solved by people in this field.

[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] In order to better describe and illustrate the embodiments of the present application, reference may be made to one or more drawings, but the additional details or examples used to describe the drawings should not be considered as limiting the scope of the utility model invention of the present application, any of the currently described embodiments or preferred methods.

[0031] In the description of the present invention, it should be noted that the terms "length", "width", "up", "down", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate that the device referred to must have a specific orientation or operate in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0033] Current sprayers have a relatively short spraying range, typically within a few dozen meters. For large or long-distance seeding, frequent equipment movement is required. This not only reduces efficiency but can also affect seeding quality due to vibrations during movement. When transporting materials over long distances, the mixing ratio can change, affecting seeding quality.

[0034] In view of this, the utility model provides a relay type spraying device. Figure 1-6 For an embodiment of the relay type spraying device provided by the present invention, please refer to Figure 1-6 The relay-type spraying device 100 includes a pumping system 1, a plurality of large relay devices 2, a plurality of small relay devices 3, and a plurality of rotary spraying operation units 4.

[0035] Specifically, the pumping system 1 includes a mixing device 11 and a first pump 12. The mixing device 11 has a mixing box 112 and a first drive mechanism 113 and a stirring blade 1133 disposed therein. The first drive mechanism 113 generally uses a motor as a driving member, whose drive shaft is connected to the main rotating shaft via a gear transmission. The stirring blade 1133 is connected to the main rotating shaft. By driving the main rotating shaft and the stirring blade 1133 to rotate, the materials in the mixing box 112, such as seeds, fertilizers, substrates, etc., are mixed. The mixing box 112 is provided with an inlet 112a and a discharge port 112b at the top and bottom, respectively. The lower discharge port 112b is connected to the first pump 12. Each large relay device 2 is preferably located on a separate platform along the slope. Each large relay device 2 comprises a second pump 21, a first mixing tank 23, and a plurality of agitators 24 within the first mixing tank 23. The discharge port 12a of the first pump 12 is connected to the second pump 21 via a feed pipe 5, and the discharge port of the second pump 21 is connected to the first mixing tank 23. Each small relay device 3 is preferably distributed along the same platform along the slope. Each small relay device 3 comprises a third pump 31, a second mixing tank 33, and an agitator 24 within the second mixing tank 33. The discharge port of the first mixing tank 23 is connected to the third pump 31, and the discharge port of the third pump 31 is connected to the second mixing tank 33. Each rotary spraying unit 4 is located on each large relay device 2 and each small relay device 3, respectively. Each rotary spraying unit 4 comprises a fourth pump 41 and a second drive mechanism 42. The second drive mechanism 42 is used to drive the fourth pump 41 to rotate. The discharge ports of the first mixing tank 23 and the second mixing tank 33 are connected to the respective fourth pumps 41. It should be understood that the first mixing tank 23 has multiple discharge ports. Furthermore, it should be noted that the feed pipe 5 connecting the first pump 12 and the second pump 21 is a rigid pipe, referred to as a pumping pipe, while the feed pipe 5 connecting the discharge port of the first mixing tank 23 and the third pump 31 is a flexible pipe, referred to as a delivery pipe. Rigid pipes are less susceptible to clogging, facilitating material pumping when there is a large height difference.

[0036] In the technical solution of the present invention, the material is preliminarily mixed by the pumping system 1, and then the large relay device 2 is used to pump the material to various platforms on the slope, and the small relay device 3 is used to continue pumping the material to other positions on the slope. The relay device can further mix the material and spray the final mixed material to various parts of the slope through the rotary spraying operation unit 4, which greatly improves the work efficiency and further improves the spraying quality.

[0037] For initial mixing of materials, see Figure 2 In one embodiment of the present invention, the first drive mechanism 113 includes a first motor 1131 and a first rotating shaft 1132. The first motor 1131 is connected to the first rotating shaft 1132 via a chain and a driven gear to increase the torque of the first rotating shaft 1132. Each stirring blade 1133 is fixedly connected to the first rotating shaft 1132 and is arranged at an angle relative to the radial direction of the first rotating shaft 1132, thereby stirring the material in the mixing box 112. In addition, to facilitate loading, a ladder 1121 and a pedestrian platform 1122 are provided on the surface of the mixing box 112 to facilitate workers to deliver materials.

[0038] If the mixing box 112 is located at the bottom of a slope, the first pump 12 needs to have a better conveying capacity. Figure 3 In one embodiment of the present invention, the first pump 12 is provided with a material storage space 12a, and the material outlet of the mixing box 112 is connected to the material storage space. The first pump 12 is a plunger pump, which has two plungers 122 movably arranged in a plunger cylinder 121 and a bend pipe 123 that can be steered. The plungers 122 can reciprocate within the plunger cylinder 121, causing the volume of the sealed working chamber to change to achieve material suction and pressure. When one of the two plunger cylinders 121 has fully drawn material from the material storage space 12a, the other just presses the drawn material into the pipeline and pumps it out from the material outlet 12b of the first pump 12, thus completing one feeding. A second motor 124 is provided at the bend 123, and the second motor 124 is connected to the bend 123 via a gear transmission. After completing one feeding, the second motor 124 drives the bend 123 to rotate, switching the interface of the bend 123 from the plunger cylinder 121 to another plunger cylinder 121. After connecting to the other plunger cylinder 121, the material continues to be drawn from the storage space 12a, and the plunger cylinder 121 that is full of material presses the material into the bend 123 and pumps it out from the discharge port 12b of the first pump 12, thereby realizing cyclic feeding. It should be noted that common driving modes of plunger pumps include manual drive, hydraulic drive, motor drive and pneumatic drive, which will not be described in detail here.

[0039] To facilitate the control of the second motor 124, in one embodiment of the present invention, the first pump 12 also includes a controller. The second motor 124 is usually a servo motor. When the two plungers 122 complete the operation, the controller transmits a signal to the second motor 124. The second motor 124 drives the bent pipe 123 to rotate, and the cylinder ports of the two plunger cylinders 121 are turned and connected, thereby realizing the reciprocating circulation of the two plungers 122.

[0040] After the initial mixing of the materials, for the convenience of spraying, please refer to Figure 4 In one embodiment of the present utility model, the large relay device 2 also includes a first water tank 22, the second pump 21 is a centrifugal pump and is interlocked with the first water tank 22. A solenoid valve is provided at the water outlet of the first water tank 22. When the material enters the feeding pipe 5, the controller of the large relay device 2 receives a signal and transmits it to the solenoid valve and the centrifugal pump. The solenoid valve channel is opened, and the water in the first water tank 22 flows through the solenoid valve through the water outlet and enters the feed port of the centrifugal pump. At the same time, the centrifugal pump is started and starts to pump water. When the material enters the feed port of the centrifugal pump through the feeding pipe 5, the sensor receives a signal, the controller of the large relay device 2 receives a signal and transmits it to the solenoid valve and the agitator 24 in the first mixing box 23. The solenoid valve channel is closed, and the centrifugal pump pumps the material into the first mixing box 23 through the feed port. At the same time, the agitator 24 starts to stir the material.

[0041] Likewise, see Figure 5 The small relay device 3 also includes a second water tank 32, and the third pump 31 is a centrifugal pump and is interlocked with the second water tank 32. A solenoid valve is provided at the water outlet of the second water tank 32. When the material enters the feeding pipe 5, the controller of the small relay device 3 receives a signal and transmits it to the solenoid valve and the centrifugal pump. The solenoid valve channel is opened, and the water in the second water tank 32 flows through the solenoid valve through the water outlet and enters the feed port of the centrifugal pump. At the same time, the centrifugal pump is started and starts to pump water. When the material is transported into the feed port of the centrifugal pump through the feeding pipe 5, the controller of the small relay device 3 receives a signal and transmits it to the solenoid valve and the agitator 24 in the second mixing box 33. The solenoid valve channel is closed, and the centrifugal pump pumps the material into the second mixing box 33 through the feed port, and the agitator 24 starts to stir the material.

[0042] See also Figure 6It should be noted that, to further mix the materials after transportation, in one embodiment of the present invention, the agitator 24 includes a third motor 241 and a plurality of vertically arranged paddles 242. The third motor 241 is connected to the plurality of paddles 242 via a gear transmission to drive them to rotate and further mix the materials. When the controller of the large relay device 2 receives a signal and transmits it to the solenoid valve and centrifugal pump, or when the materials and water enter the feed port of the first mixing box 23 or the second mixing box 33, the third motor 241 synchronously drives the paddles 242 to rotate, thereby stirring the materials and water in the box.

[0043] To enable the small relay device 3 to be transported, please refer to Figure 4 In one embodiment of the present invention, the first mixing box 23 has a plurality of discharge ports, which are respectively connected to the feed ports of the plurality of third pumps 31 through the feeding pipes 5.

[0044] To facilitate the installation of the jet grouting unit 4, please refer to Figure 5 In one embodiment of the present invention, each rotary spraying operation unit 4 is respectively installed at the discharge port of the first mixing box 23 and the second mixing box 33, and the feed port of the fourth pump 41 is directly connected to the discharge port of the first mixing box 23 or the second mixing box 33.

[0045] To achieve the spraying of mixed materials, please refer to Figure 5 In one embodiment of the present invention, the fourth pump 41 is a jet pump, and the second drive mechanism 42 includes a fourth motor 421 and a fifth motor 422. When the material in the first mixing box 23 or the second mixing box 33 reaches a set amount, the jet pump extracts the mixed material and sprays it outward. At the same time, the fourth motor 421 drives the jet pump to rotate along its circumference, and the fifth motor 422 drives the nozzle 412 of the jet pump to rotate up and down. It should be noted that the fourth motor 421 is connected to the base 411 of the jet pump via a gear transmission to drive the jet pump to rotate, and the fifth motor 422 is connected to the nozzle 412 of the jet pump via a rotating wheel to cause it to rotate up and down. A limit plate is provided at the nozzle 412, and the nozzle 412 moves within the limit slot of the limit plate.

[0046] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the concept of the present application, and these modifications and improvements fall within the scope of protection of the present application.
