Description

Technical Field

[0002] Slope greening projects have received more and more attention in recent years. However, for high slopes, traditional artificial planting methods are not applicable due to their high risks and high costs. Therefore, in the development of greening construction, sprayers have been widely used as a more efficient and safe seeding device. However, the common sprayers often have problems such as poor mixing ability and short spraying distance.

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

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0024] The spraying distance of current sprayers 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 spraying quality due to factors such as vibration during the movement of the equipment. If materials are transported over long distances, the mixing degree of the materials will change during the transportation process, affecting the spraying quality.

[0025] In view of this, the present invention 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.

[0026] 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 driving mechanism 113 and a stirring blade 1133 disposed therein. The first driving mechanism 113 generally uses a motor as a driving member, and its driving shaft is connected to the main rotating shaft through 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 upper and lower parts of the mixing box 112 are respectively provided with a feed port 112a and a discharge port 112b, and the lower discharge port 112b is connected to the first pump 12. Each large relay device 2 is preferably arranged on each platform of the slope. Each large relay device 2 has a second pump 21, a first mixing box 23 and a plurality of stirrers 24 arranged in the first mixing box 23. The discharge port 12a of the first pump 12 is connected to the second pump 21 through the feeding pipe 5, and the discharge port of the second pump 21 is connected to the first mixing box 23. Each small relay device 3 is preferably distributed along the same platform of the slope. Each small relay device 3 has a third pump 31, a second mixing box 33 and a stirrer 24 arranged in the second mixing box 33. The discharge port of the first mixing box 23 is connected to the third pump 31, and the discharge port of the third pump 31 is connected to the second mixing box 33. Each rotary spraying operation unit 4 is respectively arranged on each large relay device 2 and each small relay device 3. Each rotary spraying operation unit 4 has a fourth pump 41 and a second driving mechanism 42. The second driving mechanism 42 is used to drive the fourth pump 41 to rotate. The discharge ports of the first mixing box 23 and the second mixing box 33 are respectively connected to each fourth pump 41. It should be understood that the first mixing box 23 has multiple discharge ports, which are arranged at the top of the box in this embodiment. In addition, it should be noted that the feeding pipe 5 connecting the first pump 12 and the second pump 21 is a rigid pipe, called a pumping pipe, and the feeding pipe 5 connecting the discharge port of the first mixing box 23 and the third pump 31 is a hose, called a conveying pipe. The rigid pipe is not easy to be blocked, which is conducive to the material pumping work when the height difference is large.

[0027] 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 to pump the material to other positions on the slope. The relay device can further mix the material, and the final mixed material is sprayed to various places on the slope through the rotary spraying operation unit 4, which greatly improves the work efficiency and further improves the spraying quality.

[0028] For initial mixing of materials, refer to Figure 2 In one embodiment of the present invention, the first driving 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 through a chain and a driven gear transmission to increase the torque of the first rotating shaft 1132. Each stirring blade 1133 is fixedly connected to the first rotating shaft 1132. The stirring blade 1133 is inclined relative to the radial direction of the first rotating shaft 1132, so that the material in the mixing box 112 can be stirred. In addition, in order to facilitate material loading, a ladder 1121 and a pedestrian platform 1122 are also provided on the surface of the mixing box 112 to facilitate workers to deliver materials.

[0029] 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 leads to the material storage space. The first pump 12 is a plunger pump, which has two plungers 122 movably arranged in the plunger cylinder 121 and a bend pipe 123 that can be steered. The plunger 122 can reciprocate in the plunger cylinder 121, so that the volume of the sealed working chamber changes to achieve material suction and pressure. When one of the two plunger cylinders 121 is fully pumped from the material storage space 12a, the other just presses the pumped material into the pipeline and pumps it out from the material outlet 12b of the first pump 12, that is, one feeding is completed. A second motor 124 is provided at the bend 123, and the second motor 124 is connected to the bend 123 through a gear transmission. After completing one feeding, the second motor 124 drives the bend 123 to rotate, and switches 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, so as to realize 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.

[0030] 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 to realize the reciprocating movement of the two plungers 122.

[0031] After the material is initially mixed, for easy spraying, please refer to Figure 4 In one embodiment of the present invention, the large-scale 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-scale 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 turned on 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-scale relay device 2 receives the 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, and the agitator 24 starts to mix the material.

[0032] Likewise, see Figure 5 The small relay device 3 also includes a second water tank 32. 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 turned on 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 mix the material.

When the controller of the large relay device 2 receives a signal and transmits it to the solenoid valve and the 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 to stir the materials and water in the box.

[0034] 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 .

It should be noted that the fourth motor 421 is connected to the base 411 of the jet pump through 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 through a rotating wheel drive to make it rotate up and down. A limit plate is provided at the nozzle 412, and the nozzle 412 moves in the limit slot of the limit plate.
