Description

Technical Field

[0001] The invention relates to the technical field of vegetation restoration, in particular to a seed layer spraying device for vegetation restoration in abandoned soil fields. Background Art

[0002] When restoring vegetation on abandoned soil sites, the seed layer spraying method is often required. This is an effective vegetation restoration technology. By spraying a mixture of grass seeds, fertilizers and adhesives, the adhesive can help seeds adhere to the soil surface and reduce seed loss, helping to quickly cover exposed soil and promote plant growth.

[0003] Seed layer spraying requires the use of special spraying equipment to spray the mixture evenly on the soil surface. The spraying should be as uniform as possible to ensure the coverage of the seeds. The advantages of seed layer spraying include rapid construction, relatively low cost, and effective prevention of soil erosion and improvement of soil quality. However, it is necessary to select appropriate technologies and materials based on specific environmental conditions and vegetation restoration goals. At this stage, sprayers are generally used for seed layer spraying. Sprayers are usually equipped with large storage boxes that can load a large amount of seed mixture at one time. The equipment is mechanically driven to spray the seed mixture evenly on the soil surface, which is suitable for large-scale waste soil sites.

[0004] At present, the existing sprayers generally spray the seed mixture in the storage box onto the soil surface of the abandoned soil field through the nozzle. However, the abandoned soil field is usually not flat, but has an undulating slope. The sprayer staying on the slope will tilt, which may easily cause the center of gravity of the sprayer to become unstable and fall over, making it inconvenient to spray the seed layer on the abandoned soil field with a slope. Therefore, it does not meet the existing needs. We have proposed a seed layer spraying device for vegetation restoration in abandoned soil fields. Summary of the Invention

[0016] The present invention has the following beneficial effects:

[0017] 1. The seed layer spraying device for restoring vegetation in abandoned soil fields uses a water pump to suck the seed mixture in the storage box into the spray gun through the first pipe and the second pipe, so that the seed mixture is sprayed on the soil surface of the abandoned soil field through the spray gun. In addition, the motor drives the wire sleeve to rotate, and the threaded rod cooperates with the thread of the wire sleeve, so that the threaded rod drives the stirrer to rotate in the storage box and lift and lower at the same time, thereby stirring the seed mixture in the storage box, avoiding sedimentation or uneven distribution of the seed mixture, and making the seed spraying more uniform;

[0018] At the same time, the motor also drives the mounting base to rotate back and forth within a half-circle range, so that the mounting base drives the spray gun to swing within a half-circle range, thereby expanding the spraying range of the seed mixture, and the sprayer is stopped on the spoil field, so that the sprayer fully sprays the seed mixture on a certain area of ​​the spoil field, and then the sprayer is moved to other locations for spraying;

[0019] When the seed sprayer stays on the slope, the support frame is supported on the slope by the telescopic parts according to the inclination of the slope, and the lower end of the seed sprayer is lifted up until the seed sprayer returns to a horizontal state, making the seed sprayer more stable and not easy to tip over, thereby facilitating the spraying of seed layers on the abandoned soil field with a slope, and solving the problem as much as possible of the existing seed sprayer, which generally sprays the seed mixture in the storage box to the soil surface of the abandoned soil field through the nozzle. However, the abandoned soil field is usually not flat, but has an undulating slope. The seed sprayer staying on the slope will tilt, which may easily cause the center of gravity of the seed sprayer to be unstable and tip over, making it inconvenient to spray the seed layer on the abandoned soil field with a slope.

[0020] 2. The seed layer spraying device for restoring vegetation in abandoned soil fields is designed to rotate the knob to drive the first rack to slide up and down. The first half gear is engaged with the first rack to rotate the first half gear, thereby driving the spray gun to rotate up and down. The spraying direction of the spray gun can be adjusted by changing the up and down angles of the spray gun, thereby facilitating the adjustment of the spraying range of the seed mixture. It is particularly suitable for the spraying range of the sprayer on the slope.

[0021] 3. The seed layer spraying device for restoring vegetation in abandoned soil fields arranges a counterweight at the bottom of the sprayer to lower the center of gravity of the sprayer. When the telescopic part pushes the end of the sprayer upward, the angle between the telescopic part and the sprayer changes, so that the second half gear and the sprayer rotate relative to each other, and the second half gear is engaged with the gear, so that the gear drives the second rack to move backward, and then the second rack pushes the connecting rod to push the counterweight backward, thereby moving the overall center of gravity of the sprayer backward. Not only that, through the coordinated use of the slide groove and the counterweight, the counterweight is lowered while moving backward, and the greater the inclination of the slope, the greater the rotation angle of the second half gear relative to the sprayer, and the greater the backward movement distance of the counterweight, which effectively lowers the overall center of gravity of the sprayer, thereby making the sprayer more stable on the slope.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1: This example aims to solve the problem that the existing spraying machine generally sprays the seed mixture in the storage box to the soil surface of the spoil field through the nozzle. However, the spoil field is usually not flat, but has an undulating slope. The spraying machine that stays on the slope will tilt, which may cause the center of gravity of the spraying machine to become unstable and fall over, making it inconvenient to spray the seed layer on the spoil field with a slope. Please refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 7 and Figure 8 A seed layer spraying device for vegetation restoration in abandoned soil fields includes a seed sprayer 100 and a storage box 110 arranged on the upper side of the seed sprayer 100. An agitator 120 is arranged inside the storage box 110. The storage box 110 is configured as a square box body. The total length of the stirring rod arranged at the lower end of the agitator 120 is less than the shorter inner side length of the storage box 110 to prevent the agitator 120 from colliding with the inner wall of the storage box 110. The agitator 120 is used to stir the seed mixture in the storage box 110 to prevent the seed mixture from settling or becoming uneven.

[0033] A shell 130 is fixedly installed on the upper side of the storage box 110, and a motor 140 is fixedly installed on the inside of the shell 130. The motor 140 is used to drive the agitator 120 to rotate. A wire sleeve 141 is rotatably arranged inside the shell 130, and a bearing 142 is provided in an interference sleeve at the lower end of the wire sleeve 141. The bearing 142 is fixedly installed on the inner side of the storage box 110, and the inner ring of the bearing 142 is fixedly fitted with the outer wall of the wire sleeve 141. The outer ring of the bearing 142 is fixedly fitted with the inner wall of the storage box 110. A threaded rod 143 is fixedly connected to the upper end of the agitator 120, and the threaded rod 143 is threadedly connected to the inner side of the wire sleeve 141.

[0034] The output shaft of the motor 140 rotates back and forth between 0 degrees and 180 degrees, and the wire sleeve 141 rotates. The threaded rod 143 cooperates with the threaded wire sleeve 141 to make the agitator rise and fall. At the same time, since the resistance to the relative rotation of the threaded rod 143 and the wire sleeve 141 is greater than the resistance of the seed mixture exerted on the agitator 120, the agitator 120 rotates while rising and falling. A limiting rod 144 is fixedly installed on the inner wall of the storage box 110. The limiting rod 144 is set to a round rod. The limiting rod 144 is slidably inserted into the lower end of the agitator 120, so that the rotation or lifting of the agitator 120 is more stable.

[0035] The upper end of the housing 130 is rotatably provided with a mounting base 150, which is also driven by a motor 140. The motor 140 is provided with a double-headed motor having two output shafts. The output shaft at the lower end of the motor 140 is transmission-connected to the silk sleeve 141, and the output shaft at the upper end of the motor 140 is transmission-connected to the mounting base 150. A spray gun 160 is provided on the side of the mounting base 150. The spray gun 160 is used to spray the seed mixture. A connecting pipe 170 is plugged into the side of the storage box 110. One end of the connecting pipe 170 is provided on the storage box 110. Internally, the other end of the connecting pipe 170 is connected to the spray gun 160, and a water pump 180 is connected to the middle of the connecting pipe 170. The connecting pipe 170 includes a first pipe 171 inserted into the side of the storage box 110, and a second pipe 172 connected to the spray gun 160. The first pipe 171 is set as a hard pipe and the second pipe 172 is set as a hose to prevent the second pipe 172 from obstructing the movement of the spray gun 160. The first pipe 171 is connected to the second pipe 172, and the water pump 180 is connected to the middle of the first pipe 171.

[0036] A telescopic part 200 is provided at the bottom of the sprayer 100. The telescopic part 200 is set as an electric telescopic rod, or as a hydraulic rod. A support frame 201 is installed at the bottom of the telescopic part 200. A rotating shaft 202 is provided at the upper end of the telescopic part 200. The rotating shaft 202 is rotatably inserted into the inner side of the sprayer 100. The telescopic end of the telescopic part 200 is set downward, and the support frame 201 is set as a "U"-shaped rod with an opening downward. The middle part of the support frame 201 is fixedly connected to the telescopic end of the telescopic part 200, and in the initial state, the bottom of the support frame 201 is higher than the ground of the waste soil field to avoid obstruction to the travel of the sprayer 100. When the sprayer 100 stays on the slope, one end of the sprayer 100 provided with the telescopic part 200 is always facing the lower direction of the slope.

[0037] In this embodiment: by using the water pump 180, the seed mixture in the storage box 110 is sucked into the spray gun 160 through the first pipe 171 and the second pipe 172, so that the seed mixture is sprayed on the soil surface of the abandoned soil field through the spray gun 160. In addition, the motor 140 drives the wire sleeve 141 to rotate, and the threaded rod 143 cooperates with the thread of the wire sleeve 141, so that the threaded rod 143 drives the stirrer 120 to rotate in the storage box 110 and rise and fall at the same time, thereby stirring the seed mixture in the storage box 110, avoiding sedimentation or uneven distribution of the seed mixture, and making the seed spraying more uniform;

[0038] At the same time, the motor 140 also drives the mounting base 150 to rotate back and forth within a half-circle range, so that the mounting base 150 drives the spray gun 160 to swing within a half-circle range, thereby expanding the spraying range of the seed mixture, and the sprayer 100 is stopped on the spoil field, so that the sprayer 100 fully sprays the seed mixture on a certain area of ​​the spoil field, and then the sprayer 100 is moved to other locations for spraying;

[0039] When the seed sprayer 100 stays on the slope, according to the inclination of the slope, the support frame 201 is supported on the slope by the telescopic part 200, and the lower end of the seed sprayer 100 is lifted up until the seed sprayer 100 returns to a horizontal state, so that the seed sprayer 100 is more stable and not easy to tip over, thereby facilitating the spraying of the seed layer on the sloped spoil field, and solving the problem as much as possible of the existing seed sprayer, which generally sprays the seed mixture in the storage box to the soil surface of the spoil field through the nozzle. However, the spoil field is usually not flat, but has an undulating slope. The seed sprayer staying on the slope will tilt, which may easily cause the center of gravity of the seed sprayer to be unstable and tip over, making it inconvenient to spray the seed layer on the sloped spoil field.

[0040] Example 2: This example is intended to solve the problem that it is inconvenient to adjust the spraying direction of the spray gun 160 by changing the up and down angles of the spray gun 160, thereby easily affecting the spraying range of the seed mixture. This example is an improvement made on the basis of Example 1. For details, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 7 、 Figure 8 One end of the spray gun 160 located inside the mounting seat 150 is fixedly connected to the first half gear 190, and the first half gear 190 is rotatably set inside the mounting seat 150. A first rack 191 is also slidably inserted inside the mounting seat 150, and the first rack 191 is meshed with the first half gear 190. A first slider 192 is fixedly installed on the outside of the first rack 191, and a groove body for use with the first slider 192 is opened on the inside of the mounting seat 150. The first slider 192 is slidably inserted in the groove body of the mounting seat 150, and the first slider 192 is set as a trapezoidal block to prevent the first rack 191 from detaching from the mounting seat 150.

[0041] A knob 193 is threadedly connected to the upper side of the mounting base 150 , and the lower end of the knob 193 is located on the inner side of the mounting base 150 , and the lower end of the knob 193 is rotatably inserted into the top of the first rack 191 .

[0042] In this embodiment: turning the knob 193 drives the first rack 191 to slide up and down, and the first half gear 190 is engaged with the first rack 191, so that the first half gear 190 rotates, thereby driving the spray gun 160 to rotate up and down, so that the spraying direction of the spray gun 160 can be adjusted by changing the up and down angles of the spray gun 160, thereby facilitating the adjustment of the spraying range of the seed mixture, which is particularly suitable for the spraying range of the seed sprayer 100 on the slope.

[0043] Embodiment 3: This embodiment is intended to further promote the solution of the problem that although the spraying machine 100 is kept level on the slope by using the telescopic member 200, the overall center of gravity of the spraying machine 100 is increased, which is likely to have an adverse effect on the stability of the spraying machine 100. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 and Figure 8A second half gear 210 is fixedly installed on the top of the telescopic member 200, and the rotating shaft 202 is fixedly inserted at the center of the second half gear 210. A gear 211 is also rotatably provided on the inside of the seed sprayer 100, and the gear 211 is engaged with the second half gear 210. A second rack 212 is slidingly provided on the inside of the seed sprayer 100, and the second rack 212 is engaged with the gear 211. A second slider 213 is fixedly installed on the upper side of the second rack 212. A groove body for use with the second slider 213 is opened on the inside of the seed sprayer 100. The second slider 213 is slidably inserted in the groove body in the seed sprayer 100, and the second slider 213 is set as a trapezoidal block to prevent the second rack 212 from detaching from the seed sprayer 100.

[0044] A counterweight 220 is slidingly provided on the inside of the seed sprayer 100. The counterweight 220 is located at the bottom of the seed sprayer 100, thereby lowering the center of gravity of the seed sprayer 100 and making the seed sprayer 100 more stable. A slide groove 221 is provided on the inside of the seed sprayer 100 for use with the counterweight 220. The counterweight 220 is slidingly provided in the slide groove 221, and the bottom of the slide groove 221 is tilted downward away from the end of the second rack 212. A connecting rod 222 is provided on the outside of the second rack 212, and one end of the connecting rod 222 is rotatably connected to the counterweight 220 by rivets.

[0045] A fixed block 230 is slidingly provided on the side of the second half gear 210, and a fixed rod 231 is threadedly connected to the side of the sprayer 100. The end of the fixed rod 231 is rotatably connected to the fixed block 230, and a tooth groove that can mesh with the second half gear 210 is provided on the side of the fixed block 230 close to the second half gear 210.

[0046] A connecting plate 232 is fixedly installed at the end of the second rack 212, and a first moving gear 233 and a second moving gear 234 are rotatably installed on the side of the connecting plate 232. A third rack 235 is fixedly installed on the inner side of the sprayer 100, and a fourth rack 236 is also slidably arranged on the inner side of the sprayer 100. The third rack 235 is arranged above the first moving gear 233 and the second moving gear 234, and the fourth rack 236 is arranged below the first moving gear 233 and the second moving gear 234, and the third rack 235 and the fourth rack 236 are respectively engaged with the upper and lower sides of the first moving gear 233 and the second moving gear 234, and the other end of the connecting rod 222 is rotatably connected to the fourth rack 236 by a rivet.

[0047] In this embodiment: by arranging a counterweight block 220 at the bottom of the spraying machine 100, the center of gravity of the spraying machine 100 is lowered. When the telescopic member 200 pushes the end of the spraying machine 100 upward, the angle between the telescopic member 200 and the spraying machine 100 changes, so that the second half gear 210 and the spraying machine 100 rotate relative to each other, so that the second half gear 210 is meshed with the gear 211, so that the gear 211 drives the second rack 212 to move backward, and by rotating the fixing rod 231, the fixing block 230 is pushed to engage with the second half gear 210, limiting the rotation of the second half gear 210, thereby limiting the activity of the telescopic member 200, so that the telescopic member 200 supports the spraying machine 100 more stably;

[0048] The second rack 212 pushes the connecting plate 232, so that the connecting plate 232 drives the upper sides of the first moving gear 233 and the second moving gear 234 to engage with the third rack 235. At the same time, the lower sides of the first moving gear 233 and the second moving gear 234 engage with the fourth rack 236, so that the moving distance of the fourth rack 236 is greater than the moving distance of the second rack 212. Therefore, this amplified moving distance is transmitted to the counterweight block 220 through the connecting rod 222, so that the counterweight block 220 can be moved in a shorter limited space. , the moving distance of the counterweight block 220 is greater, so that the counterweight block 220 is moved into place, thereby moving the overall center of gravity of the sprayer 100 backward. Not only that, through the coordinated use of the slide groove 221 and the counterweight block 220, the counterweight block 220 is lowered while moving backward, and the greater the inclination of the slope, the greater the rotation angle of the second half gear 210 relative to the sprayer 100, and the greater the backward movement distance of the counterweight block 220, which effectively lowers the overall center of gravity of the sprayer 100, thereby making the sprayer 100 more stable when on the slope.

[0049] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
