[0040] In the following text, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary in nature rather than restrictive.
[0041] Refer to Figures 1-6 , which shows a wet spraying machine in a preferred embodiment of the present utility model, including:
[0042] A machine body 1, the machine body 1 having a mixing chamber 11;
[0043] A driving device 2, the driving device 2 being provided on the machine body 1, and the driving device 2 having an output end;
[0044] A stirring mechanism 3, the stirring mechanism 3 being provided in the mixing chamber 11, the stirring mechanism 3 being connected to the output end, and the stirring mechanism 3 being able to rotate with the output end;
[0045] A pump body 4, the pump body 4 being provided on the machine body 1, the inlet 41 of the pump body being communicated with the bottom of the mixing chamber 11, and the pump body 4 being used to provide liquid flow power;
[0046] A nozzle 5, the nozzle 5 being provided on the machine body 1, the inlet of the nozzle 5 being communicated with the outlet of the pump body 4, and the outlet of the nozzle 5 being communicated with the lower part of the mixing chamber 11.
[0047] In the wet spraying machine of the present utility model, during operation, the driving device 2 can be used to drive the stirring mechanism 3, so that the stirring mechanism 3 rotates in the mixing chamber 11 to realize stirring of the mixture in the mixing chamber 11. At the same time, the pump body 4 can be used to pump out the mixture in the mixing chamber 11 from the bottom and pump it to pass through the nozzle 5, and finally spray out through the nozzle 5, so that the mixture flows back from the lower part of the mixing chamber 11 to the mixing chamber 11. During the process of the mixture flowing back, the mixture flowing back at high speed can realize tumbling of the mixture located in the lower part of the mixing chamber, and cooperate with the stirring mechanism 3 to stir the mixture evenly, which can effectively avoid precipitation of grass seeds in the mixture, thereby facilitating improvement of the spraying uniformity of grass seeds.
[0048] See Figure 3 , in an embodiment, the extending direction of the outlet of the nozzle 5 is parallel to the rotation center line of the stirring mechanism 3. In this way, the mixture sprayed out through the nozzle 5 can be ejected along the direction parallel to the rotation center line of the stirring mechanism 3, and cooperate with the stirring mechanism 3 to realize dead-angle-free tumbling and stirring of the mixture in the mixing chamber 11, making the mixture stirring more uniform.
[0049] See Figure 4 , in an embodiment, the outlet diameter of the nozzle 5 is smaller than the inlet diameter 41 of the pump body to further increase the reflux flow rate of the mixture, improve the tumbling force on the mixture, and thus facilitate further improvement of the mixing uniformity of the mixture.
[0050] See Figure 4 , in an embodiment, the number of nozzles 5 is at least two, and at least two nozzles 5 are arranged at intervals along the direction perpendicular to the rotation center line of the stirring mechanism 3. In this way, the reflux flow rate of the mixture can be increased, the tumbling force can be improved, and thus the mixing uniformity and efficiency of the mixture can be improved.
[0051] In this embodiment, the number of nozzles 5 can be two, or one or three or more, and can be specifically set according to actual needs.
[0052] In an embodiment, both the pump body 4 and the nozzle 5 are located on the same side of the machine body 1 to shorten the length of the connecting pipeline between the outlet of the pump body 4 and the inlet of the nozzle 5, which is beneficial to reducing costs and facilitating installation. At the same time, it can also improve the space utilization rate on the same side of the machine body 1, which is beneficial to the compact structure setting of the wet spraying machine.
[0053] See Figure 5 , in an embodiment, the stirring mechanism 3 includes:
[0054] A stirring shaft 31, the stirring shaft 31 is rotatably arranged on the machine body 1, and the stirring shaft 31 is connected to the output end;
[0055] Multiple stirring blades 32 are arranged at intervals on the stirring shaft 31. The included angle between the stirring blade 32 and the stirring shaft 31 is 58°-62°, that is, the stirring blade 32 is inclined relative to the stirring shaft 31, and the inclination angle of the stirring blade 32 relative to the stirring shaft 31 is 58°-62°. Within this inclination angle range, the stirring blade 32 can generate a vortex phenomenon during the stirring process, making the stirring more sufficient and uniform, and effectively avoiding the precipitation of grass seeds in the mixture.
[0056] In one embodiment, the included angle between the stirring blade 32 and the stirring shaft 31 is 60°. Within this inclination angle, the stirring blade 32 can generate a more powerful vortex phenomenon during the stirring process, making the stirring more sufficient and uniform.
[0057] Of course, in other embodiments, the included angle between the stirring blade 32 and the stirring shaft 31 can be 58°, 59°, 61°, 62°, and the stirring can also be made more sufficient and uniform.
[0058] See Figure 5 , in one embodiment, the stirring blade 32 has a first connection hole that axially penetrates the stirring blade 32;
[0059] The stirring mechanism 3 further includes:
[0060] A connecting ring 33 is sleeved on the outer periphery of the stirring shaft 31. The connecting ring 33 has a second connection hole that axially penetrates the connecting ring 33;
[0061] A fastener 34, the head of the fastener 34 abuts against the side of the stirring blade 32 facing away from the connecting ring 33, and the rod portion of the fastener 34 sequentially passes through the first connection hole and the second connection hole;
[0062] A fastening nut 35 is screwed onto the rod portion of the fastener 34, and the fastening nut 35 abuts against the side of the connecting ring 33 facing away from the stirring blade 32. In this way, during installation, the stirring blade 32 can be reliably connected to the connecting ring 33 through the cooperation of the fastener 34 and the fastening nut 35, thereby realizing the reliable fixation of the stirring blade 32 on the stirring shaft 31, reducing the installation difficulty of the stirring blade 32, and making the installation of the stirring blade 32 more convenient.
[0063] Of course, in other embodiments, the stirring blade 32 can also be fixed to the stirring shaft 31 by welding.
[0064] In one embodiment, the connecting ring 33 is integrally provided with the stirring shaft 31, that is, the connecting ring 33 and the stirring shaft 31 are made by an integral molding method, so as to improve the connection reliability between the connecting ring 33 and the stirring shaft 31. At the same time, the connecting ring 33 and the stirring shaft 31 are free of connecting parts, which simplifies the structure and can further reduce costs.
[0065] In other embodiments, the connecting ring 33 is welded to the stirring shaft 31, which can also improve the connection reliability between the connecting ring 33 and the stirring shaft 31.
[0066] In one embodiment, the number of the first connection holes, the second connection holes, the fasteners 34 and the fastening nuts 35 is at least two. The rod parts of the plurality of fasteners 34 pass through the aligned first connection holes and second connection holes one by one, and the plurality of fastening nuts 35 are screwed to the rod parts of the corresponding fasteners 34 one by one, so as to further improve the connection stability between the stirring blade 32 and the connecting ring 33, so that the stirring blade 32 is more reliably fixed on the stirring shaft 31.
[0067] See Figure 6 , in one embodiment, the wet spraying machine further includes:
[0068] A valve body 6, the inlet of the valve body 6 is communicated with the outlet of the pump body 4, the first outlet of the valve body 6 is communicated with the inlet of the nozzle 5, and the valve body 6 is used to control the on-off between the inlet of the valve body 6 and the first outlet of the valve body 6 and the on-off between the inlet of the valve body 6 and the second outlet of the valve body 6;
[0069] A spray gun 7, the spray gun 7 is arranged outside the machine body 1, and the inlet of the spray gun 7 is communicated with the second outlet of the valve body 6. That is, by controlling the valve body 6 to make the inlet of the valve body 6 communicate or disconnect from the first outlet of the valve body 6, the communication or disconnection between the nozzle 5 and the inlet 41 of the pump body can be realized. At the same time, by controlling the valve body 6 to make the inlet of the valve body 6 communicate or disconnect from the second outlet of the valve body 6, the communication or disconnection between the spray gun 7 and the inlet 41 of the pump body can be realized. When the spray gun 7 is communicated with the inlet 41 of the pump body, the pump body 4 can be used to pump the uniformly mixed mixture to the spray gun 7, and finally spray it on the surface of the working soil through the spray gun 7 to form a soft and stable covering layer covering the grass seeds. Among them, since the nozzle 5 and the spray gun 7 share the same pump body 4, the utilization rate of the pump body 4 can be improved, and at the same time, it is also beneficial to reduce costs.
[0070] See Figure 3, in one embodiment, the machine body 1 further has an installation cavity 12. The installation cavity 12 and the mixing cavity 11 are arranged in sequence along the length direction of the machine body 1. The driving device 2 and the pump body 4 are both located in the installation cavity 12. Since the installation cavity 12 and the mixing cavity 11 are arranged along the length direction of the machine body 1, the space utilization rate in the length direction of the machine body 1 can be improved, and the space in the width direction or height direction of the machine body 1 will not be occupied, which is more conducive to the overall compact setting of the wet spraying machine.
