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 an abandoned soil field. Background Art

[0002] When restoring vegetation on abandoned landfills, 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, help quickly cover exposed soil and promote plant growth.

[0003] Seed layer spraying requires the use of special spraying equipment to evenly spray the mixture 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 quick construction, relatively low cost, and effective prevention of soil erosion and improvement of soil quality. However, it is necessary to select appropriate technology and materials according to 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 onto the soil surface, which is suitable for large areas of abandoned 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 a 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 tip 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 vegetation restoration in the abandoned soil field 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, so as to stir the seed mixture in the storage box, avoid precipitation or uneven distribution of the seed mixture, and make the seed spraying more uniform;

[0018] At the same time, the motor also drives the mounting seat to reciprocate within a half-circle range, so that the mounting seat 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 abandoned soil field, so that the sprayer fully sprays the seed mixture on a certain area of ​​the abandoned soil field, and then the sprayer is moved to other positions for spraying;

[0019] When the seed sprayer stays on the slope, according to the inclination of the slope, the support frame is supported on the slope by the telescopic parts, 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 of existing seed sprayers as much as possible. Generally, the seed mixture in the storage box is sprayed onto the soil surface of the abandoned soil field through a 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 used. By turning the knob, the first rack is driven to slide up and down. The first half gear is engaged with the first rack, so that the first half gear rotates, thereby driving the spray gun to rotate up and down. It is convenient to adjust the spraying direction of the spray gun by changing the up and down angles of the spray gun, thereby facilitating the adjustment of the spraying range of the seed mixture, which is particularly suitable for the spraying range of the seed sprayer on the slope.

[0021] 3. The seed layer spraying device for restoring vegetation in abandoned soil fields lowers the center of gravity of the seed sprayer by arranging a counterweight at the bottom of the seed sprayer. When the telescopic member lifts the end of the seed sprayer upward, the angle between the telescopic member and the seed sprayer changes, so that the second half gear and the seed sprayer rotate relative to each other, and the second half gear engages 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 seed sprayer backward. Moreover, 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 seed sprayer, and the greater the backward movement distance of the counterweight, which effectively reduces the overall center of gravity of the seed sprayer, thereby making the seed sprayer more stable on the slope.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0032] Embodiment 1: This embodiment aims to promote the solution of the existing spraying machine, 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 spraying machine staying on the slope will tilt, which may easily cause the center of gravity of the spraying machine to be unstable and fall over, making it inconvenient to spray the seed layer on the abandoned soil 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 arranged in 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 inner side 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, and 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 reciprocates between 0 and 180 degrees, and the wire sleeve 141 rotates. The threaded rod 143 cooperates with the threaded thread of the wire sleeve 141 to make the agitator rise and fall. At the same time, since the resistance of the relative rotation between the threaded rod 143 and the wire sleeve 141 is greater than the resistance of the seed mixture on the agitator 120, the agitator 120 rotates while rising and falling. A limit rod 144 is fixedly installed on the inner wall of the storage box 110. The limit rod 144 is set to a round rod. The limit rod 144 is slidably inserted at 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 seat 150, which is also driven by a motor 140. The motor 140 is provided as a double-headed motor with 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 seat 150. A spray gun 160 is provided on the side of the mounting seat 150, and 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, and 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 configured as a hard pipe, and the second pipe 172 is configured 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 arranged at the bottom of the seed sprayer 100. The telescopic part 200 is arranged 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 arranged at the upper end of the telescopic part 200. The rotating shaft 202 is rotatably inserted into the inner side of the seed sprayer 100. The telescopic end of the telescopic part 200 is arranged downward, and the support frame 201 is arranged 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 seed sprayer 100. When the seed sprayer 100 stays on the slope, one end of the seed sprayer 100 provided with the telescopic part 200 is always facing the direction of the lower 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 agitator 120 to rotate in the storage box 110 and lift and lower at the same time, so as to stir the seed mixture in the storage box 110, avoid precipitation or uneven distribution of the seed mixture, and make the seed spraying more uniform;

[0038] At the same time, the motor 140 also drives the mounting seat 150 to reciprocate within a half-circle range, so that the mounting seat 150 drives the spray gun 160 to swing within a half-circle range, thereby expanding the spraying range of the seed mixture, and the seed sprayer 100 is stopped on the abandoned soil field, so that the seed sprayer 100 fully sprays the seed mixture on a certain area of ​​the abandoned soil field, and then the seed sprayer 100 is moved to other positions 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 abandoned soil field with a slope, and solving the problem as much as possible that the existing seed sprayer generally sprays the seed mixture in the storage box onto the soil surface of the abandoned soil field through a 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 can 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.

[0040] Embodiment 2: This embodiment is intended to promote the solution of the problem that it is inconvenient to adjust the spraying direction of the spray gun 160 by changing the up and down angle of the spray gun 160, thereby easily affecting the spraying range of the seed mixture. This embodiment is an improvement made on the basis of Embodiment 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 a 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. A groove body used in conjunction 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 seat 150 , and the lower end of the knob 193 is located on the inner side of the mounting seat 150 , and the lower end of the knob 193 is rotatably inserted into the top of the first rack 191 .

[0042] In the present 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 a 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 arranged on the inner side of the seed sprayer 100, and the gear 211 is meshed with the second half gear 210. A second rack 212 is slidably arranged on the inner side of the seed sprayer 100, and the second rack 212 is meshed with the gear 211. A second slider 213 is fixedly installed on the upper side of the second rack 212. A groove body used in conjunction with the second slider 213 is opened on the inner side of the seed sprayer 100, and the second slider 213 is slidably inserted in the groove body in the seed sprayer 100, and the second slider 213 is arranged as a trapezoidal block to prevent the second rack 212 from detaching from the seed sprayer 100.

[0044] A counterweight 220 is slidably arranged on the inner side of the seed sprayer 100, and 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 for use with the counterweight 220 is provided on the inner side of the seed sprayer 100, and the counterweight 220 is slidably arranged in the slide groove 221, and the bottom of the slide groove 221 is inclined downwardly arranged away from the end of the second rack 212, and a connecting rod 222 is arranged on the outer side of the second rack 212, and one end of the connecting rod 222 is rotatably connected to the counterweight 220 by rivets.

[0045] A fixing block 230 is slidingly provided on the side of the second half gear 210, and a fixing rod 231 is threadedly connected to the side of the seed sprayer 100. The end of the fixing rod 231 is rotatably connected to the fixing block 230, and a tooth groove that can mesh with the second half gear 210 is provided on the side of the fixing 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. The third rack 235 and the fourth rack 236 are respectively meshed 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 seed sprayer 100, the center of gravity of the seed sprayer 100 is lowered, and when the telescopic member 200 pushes the end of the seed sprayer 100 upward, the angle between the telescopic member 200 and the seed sprayer 100 is changed, so that the second half gear 210 and the seed sprayer 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, and the rotation of the second half gear 210 is limited, thereby limiting the activity of the telescopic member 200, so that the telescopic member 200 supports the seed sprayer 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 mesh with the third rack 235. At the same time, the lower sides of the first moving gear 233 and the second moving gear 234 mesh 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 enlarged 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 seed 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 seed sprayer 100, and the greater the backward movement distance of the counterweight block 220, which effectively reduces the overall center of gravity of the seed sprayer 100, thereby making the seed sprayer 100 more stable when on the slope.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0050] The above is only a preferred embodiment of the present invention. 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 the scope of protection of the present invention.
