Description

Technical Field

[0001] The invention relates to the technical field of ecological restoration, and in particular to construction equipment and a construction method of an SPF high-performance spraying matrix. Background Art

[0002] SPF high-performance spraying matrix technology is widely used in ecological restoration projects such as road slopes, mine wounds, and river restoration. SPF high-performance spraying matrix is ​​a composite spraying matrix material with heat-refined high-performance spraying fiber as the main carrier, also known as "high-performance spraying matrix" or "SPF matrix".

[0003] During spraying, water is usually used as a carrier to mix grass seeds, flowers, trees and other seeds with fertilizers, polymer adhesives, and water retaining agents at one time. At the same time, a large amount of organic matter such as wood chips, paper fibers, cotton fibers, and straw that improve the soil can be mixed, and an appropriate amount of yellow loam, red loam, sandy loam, clay or some strongly weathered petrified soil is added. Stir evenly to form a large-proportion, high-concentration slurry, and then spray evenly onto the target slope. Since spraying requires the maximum soil particles to be less than or equal to 10mm, it is usually necessary to use a drum screen or a vibrating screen to screen the soil.

[0004] In the prior art, for example, the patent document with announcement number CN117859469B announces a soil spraying device for ecological restoration, and also discloses a technical solution for screening the soil using a screen plate and crushing large particles of soil. However, in actual application, the soil particles can easily clog the sieve holes on the screen plate, thereby causing the subsequent soil to be unable to pass through the sieve holes and fall into the box. At the same time, since there may be some stones in the soil, the material of the stones is hard and cannot be crushed by the crushing mechanism, and it will cause the equipment to get stuck.

[0029] Spraying construction: The vehicle moves the spraying mechanism to the slope surface to be sprayed, and evenly sprays the configured SPF high-performance spraying matrix onto the slope surface;

[0030] Covering maintenance: After spraying is completed, cover the slope with non-woven fabric for moisturizing maintenance.

[0031] Beneficial effects of the present invention:

[0032] (1) When the driving module of the present invention drives the grinding roller to move along the arc-shaped screen plate, the grinding roller can rotate accordingly. During the rotation of the grinding roller, each row of spray holes on the roller wall can correspond to each row of sieve holes on the arc-shaped screen plate in sequence. When the gas supply mechanism supplies gas to the grinding roller, as the gas is sprayed from the spray holes, an impact force can be simultaneously given to the soil blocked in the sieve holes, thereby achieving the effect of unblocking the sieve holes and avoiding clogging of the sieve holes. In this process, the gas sprayed from the sieve holes can also blow away the soil on the arc-shaped screen plate to avoid the phenomenon of soil particles gathering on the arc-shaped screen plate, further improving the grinding and screening effect, and allowing small particles of ground soil to be quickly discharged from the sieve holes;

[0033] (2) In the present invention, when some large-particle stones fall onto the arc-shaped screen plate, the stones cannot fall through the screen holes. Since the diameter of the stones is larger than the gap between the grinding roller and the arc-shaped screen plate, the stones can be pushed to one side edge of the arc-shaped screen plate as the grinding roller moves. At this time, as the gas is ejected from the nozzle hole, the stones can be pushed away from the arc-shaped screen plate under the impact of the gas. The present invention can effectively separate large-particle stones and avoid affecting the normal operation of the equipment.

[0034] (3) The outer wall of the grinding roller of the present invention is slidably fitted with the inner wall of the arc cover, so that when the grinding roller moves, exhaust can only be carried out through one or at most two rows of nozzles facing the notch of the arc cover, thereby increasing the exhaust pressure, so that the gas has a corresponding impact force, which can flush out the gas blocked in the sieve hole.

DETAILED DESCRIPTION

[0046] 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.

[0047] Example 1

[0048] See also Figure 1 As shown, the present invention is a construction equipment for SPF high-performance spraying matrix, including a vehicle body 1 for walking and displacement, on which a spraying mechanism for spraying the matrix is ​​fixedly arranged; specifically, in this embodiment, the vehicle body 1 drives the spraying mechanism to move to one side of the slope to be repaired, and during this process, the matrix is ​​evenly sprayed on the slope surface through the spraying mechanism.

[0049] In this embodiment, the spraying mechanism includes a material storage module 2, a grinding module 3, a mixing module 4 and a spraying module 5;

[0050] The material storage module 2 is arranged on the vehicle body 1 and is used to store the soil to be screened;

[0051] The grinding module 3 is arranged at the bottom of the storage module 2, and is used to grind the soil so that the soil particles meet the requirements of spraying; the soil in this embodiment is limited to dry soil, and the particle size of the required soil particles is less than or equal to 10mm;

[0052] The mixing module 4 is arranged at the bottom of the grinding module 3, and is used to uniformly mix the soil particles with the spraying matrix to form a high-concentration slurry; the spraying matrix in this embodiment is plant seeds, fertilizers, polymer adhesives, water retaining agents, water and other substances. This embodiment does not limit the specific raw materials of the spraying matrix, so as to meet the actual repair needs;

[0053] The spraying module 5 is arranged on one side of the mixing module 4, and is used to spray the mixed high-concentration slurry evenly onto the slope to be repaired;

[0054] It can be explained that, in this embodiment, the soil is first stored in the storage module 2, and the soil in the storage module 2 can fall into the grinding module 3 under the action of gravity. The soil particles are ground by the grinding module 3 so that the particle size of the soil particles meets the spraying requirements. After the grinding is completed, the soil that meets the particle diameter requirements falls into the mixing module 4 under the action of gravity. The soil is mixed with the spraying matrix through the mixing module 4 to form a high-concentration slurry, and finally it is evenly sprayed onto the slope to be repaired through the spraying module 5.

[0055] See also Figure 2-Figure 4 The grinding module 3 includes an arc-shaped screen plate 301 arranged between the material storage module 2 and the mixing module 4, and a plurality of screening groups are arranged on the arc-shaped screen plate 301 in a circumferential array, each screening group includes a plurality of sieve holes 303, and a grinding roller 304 is arranged on the arc-shaped screen plate 301 in a rolling manner, and the grinding roller 304 is connected to a driving module that drives it to reciprocate along the inner surface of the arc-shaped screen plate 301; specifically, the soil in the material storage module 2 falls onto the arc-shaped screen plate 301, and the grinding roller 304 is driven by the driving module to reciprocate along the inner surface of the arc-shaped screen plate 301 to grind the soil particles, and the ground small particles of soil can pass through the sieve holes 303 and fall into the mixing module 4 to be mixed with the spraying matrix.

[0056] In this embodiment, the grinding roller 304 is a hollow structure, and a plurality of jet groups are arranged in a circumferential array on the roller wall of the grinding roller 304, each jet group includes a plurality of jet holes 311, and the grinding roller 304 is connected to a gas delivery mechanism, and the gas delivery mechanism is used to deliver gas to the grinding roller 304; it can be explained that when the driving module drives the grinding roller 304 to move along the arc-shaped screen plate 301, the grinding roller 304 can rotate accordingly, which can be referred to Figure 5During the rotation of the grinding roller 304, each row of spray holes 311 on the roller wall can correspond to each row of sieve holes 303 on the arc sieve plate 301 in sequence, and then when the gas supply mechanism supplies gas to the grinding roller 304, as the gas is sprayed from the spray holes 311, an impact force can be simultaneously given to the soil blocked in the sieve holes 303, thereby achieving the effect of unblocking the sieve holes 303 and avoiding the clogging of the sieve holes 303. In this process, the gas sprayed from the sieve holes 303 can also blow away the soil on the arc sieve plate 301 to avoid the aggregation of soil particles on the arc sieve plate 301, further improving the grinding and screening effect, and allowing the ground small particles of soil to be quickly discharged from the sieve holes 303.

[0057] It should also be noted that when some large-particle stones fall onto the curved screen plate 301, the stones cannot pass through the screen holes 303 and fall down. Since the diameter of the stones is larger than the gap between the grinding roller 304 and the curved screen plate 301, the stones can be pushed to one side edge of the curved screen plate 301 along with the movement of the grinding roller 304. For details, please refer to Figure 7 At this time, as the gas is ejected from the nozzle 311, the stones can be pushed away from the arc screen plate 301 under the impact of the gas. This embodiment can effectively separate large-particle stones and avoid affecting the normal operation of the equipment.

[0060] See also Figure 2-Figure 3 The mixing module 4 includes a mixing box 401 arranged at the bottom of the arc-shaped screen plate 301, and the mixing box 401 is fixed on the vehicle body 1, wherein a spiral stirring blade 403 is rotatably arranged in the mixing box 401, and the spiral stirring blade 403 is fixed to the output end of the second motor 402 fixedly arranged on the outside of the mixing box 401; it can be explained that when the soil and the spraying matrix are added to the mixing box 401, the second motor 402 is started to drive the spiral stirring blade 403 to rotate, so as to mix the soil and the spraying matrix;

[0061] It should be noted that the horizontal projection area of ​​the arc sieve plate 301 is smaller than the area of ​​the top opening end of the mixing box 401. When adding a spraying matrix other than soil, it can be added through the gap between the arc sieve plate 301 and the top opening end of the mixing box 401.

[0062] In this embodiment, in order to improve the screening efficiency of the curved screen plate 301, please refer to Figure 2-Figure 3 , slide rails 405 are fixedly arranged on both sides of the open end of the mixing box 401, and L-shaped brackets 406 are arranged on both sides of the storage box 201, one side of the L-shaped bracket 406 is fixed to the storage box 201 and the arc-shaped screen plate 301, and the L-shaped brackets 406 on both sides are slidably connected to the slide rails 405, wherein a vibrating cylinder 409 is fixedly arranged on one side of the mixing box 401, and the driving end of the vibrating cylinder 409 is fixed to the L-shaped bracket 406; it can be explained that, in this embodiment, the vibrating cylinder 409 drives the L-shaped bracket 406 to slide back and forth on the slide rail 405, and the L-shaped bracket 406 can synchronously drive the storage box 201 and the arc-shaped screen plate 301 to vibrate synchronously, which can improve the falling efficiency of the soil in the storage box 201 on the one hand, and accelerate the falling of the soil through the sieve hole 303 on the other hand, thereby improving the discharge efficiency.
