Description

Technical Field

[0001] The invention relates to the technical field of slope repair equipment, and in particular to a slope repair equipment and a repair method for an open-pit mine dump. Background Art

[0002] The open-pit mine spoil dump is a designated place for stacking stripping materials during the open-pit mining process. After the mine is closed, the spoil dump can be transformed into a usable land resource through land reclamation and ecological restoration measures, which will help restore the ecological environment of the mining area. Among the slope restoration methods, soil spraying is one of the common methods. Soil spraying is to mix soil, grass seeds, fertilizers, water, etc. under the action of a stirring device, and send them to the spraying gun through a conveying system for spraying so that they are evenly covered on the slope surface.

[0003] The spraying angle and spraying distance of the spraying gun need to be controlled manually, but due to the large reaction force of the spraying gun, it is difficult to control it stably for a long time, which easily leads to uneven spraying coverage, resulting in uneven emergence of seedlings on the slope and difficulty in forming a complete vegetation coverage. In the subsequent slope where the vegetation is sparse, soil and water loss is prone to occur. The patent with the prior art announcement number CN115296522A discloses a mountain slope soil spraying device, which can realize automatic reciprocating spraying and control the number of spraying layers to ensure that the thickness of the substrate under the seeds is appropriate.

[0004] However, the prior art still has the following defects: since the entire spraying equipment remains stationary during operation and the internal pressure of the spraying gun is always kept constant, when the spraying distance of the spraying gun is short, the foreign soil sprayed by the spraying gun is in the form of a water column and cannot be dispersed in time. On the one hand, the large impact force will cause erosion of the slope soil and damage the slope structure. On the other hand, the foreign soil tends to flow downward on the slope quickly, resulting in waste of foreign soil materials and difficulty in achieving uniform coverage. Summary of the invention

[0005] In view of the fact that the existing technical problems exist in the process of automatic spraying of imported soil, the spray gun cannot change the problem of scouring the slope and uneven spraying, thus a slope repair equipment for open-pit mine spoil dump is proposed.

[0006] The purpose is to disturb the foreign soil sprayed by the spray gun through the spoiler component as the spraying angle is gradually reduced, thereby reducing the impact force on the slope and achieving uniform coverage of the slope by the foreign soil.

[0007] The technical solution of the present invention is a slope repair device for an open-pit mine dump, comprising a soil-injection spraying machine body and a spraying gun, a delivery pump pipe is arranged on the top of the soil-injection spraying machine body, the spraying gun is sealed and rotatably connected to the output end of the delivery pump pipe, and a spraying auxiliary mechanism is arranged between the soil-injection spraying machine body and the spraying gun;

[0008] The spraying auxiliary mechanism includes a frame fixedly connected to the top of the soil spraying machine body, and a horizontal plate movably connected to the top of the frame, one end of the horizontal plate is fixedly connected to the spraying gun, and a pushing sleeve and a positioning sleeve are sequentially arranged on the gun body of the spraying gun near the muzzle, the pushing sleeve is slidably connected to the spraying gun, the positioning sleeve is fixedly sleeved with the spraying gun, and the pushing sleeve is located between the positioning sleeve and the muzzle of the spraying gun;

[0009] The push sleeve is provided with a spoiler assembly, and the spoiler assembly is used to change the soil spraying range of the spraying gun;

[0010] A support frame is provided on the top of the horizontal plate at a position corresponding to the spray gun, and support plates are vertically slidably connected to the two symmetrical outer walls of the support frame. The upper end of the support plate is hingedly engaged with the positioning sleeve, and inclined guide plates are provided on the two symmetrical inner walls of the support frame. When the push sleeve contacts the guide plate, the spoiler assembly is driven to retract.

[0011] By adopting the above technical scheme, the conveying pump in the main body of the foreign soil spraying machine can convey the mixed foreign soil into the conveying pump pipe, and spray the foreign soil onto the slope of the open-pit mine spoil dump through the nozzle of the spraying gun. As the spraying angle of the spraying gun gradually decreases, the pushing sleeve follows the spraying gun to descend and contact the guide plate, and the pushing sleeve moves toward the muzzle end of the spraying gun, which can drive the spoiler component to retract, interfere with the path of the foreign soil sprayed by the spraying gun, and change the foreign soil originally sprayed by the spraying gun from a water column shape to a fan shape, thereby reducing the soil scouring on the slope without reducing the injection flow rate. At the same time, the foreign soil is sprayed onto the slope in a fan shape, which can prevent the foreign soil from flowing downward quickly on the slope, reduce material waste and achieve uniform coverage.

[0012] Furthermore, the spoiler assembly includes a support ring fixedly sleeved on the gun body near the muzzle end of the spray gun, two spoiler plates are symmetrically hinged on the support ring, a connecting rod is slidably connected to the side of the spoiler away from the muzzle of the spray gun, the other end of the connecting rod is hinged to the outer wall of the push sleeve, and two guide wheels are symmetrically rotatably connected to the outer wall of the push sleeve.

[0013] By adopting the above technical scheme, two spoilers are respectively arranged on the upper and lower sides of the muzzle of the spray gun. When the spraying angle of the spray gun decreases, the guide wheel can roll in contact with the guide plate to move the push sleeve toward the muzzle of the spray gun, and the spoiler is driven to rotate by the connecting rod. When the distance on the right side of the two spoilers is smaller than the diameter range of the water column-shaped guest soil sprayed by the spray gun, the moving range of the sprayed guest soil can be changed to change it into a fan shape.

[0014] Furthermore, an anti-overflow cover is fixedly sleeved on the gun body at the muzzle end of the spray gun. The anti-overflow cover has a U-shaped structure and is made of flexible rubber material. The edges of the two spoilers on the facing sides are respectively fixedly connected to the openings on both sides of the anti-overflow cover.

[0015] By adopting the above technical solution, the anti-overflow cover can shield the other sides of the two spoilers, preventing part of the foreign soil from overflowing through the sides under the action of the spoiler, thereby avoiding the waste of foreign soil resources.

[0016] Furthermore, a plurality of reset members are connected to the push sleeve and the positioning sleeve in a ring array.

[0017] By adopting the above technical solution, when the guide wheel is not in contact with the guide plate, the reset member can drive the pushing sleeve to approach the side of the positioning sleeve, so that the right sides of the two spoilers maintain the maximum distance, avoiding interference with the water column-shaped foreign soil sprayed by the spray gun, so that the spray gun maintains its spraying ability and sprays foreign soil on the distant slope.

[0018] Furthermore, a swing mechanism is provided on the spraying auxiliary mechanism, and the swing mechanism includes a servo motor fixedly arranged through the horizontal plate, the output end of the servo motor extends to directly below the horizontal plate, and the output end of the servo motor is connected to a driving shaft via a coupling, and the other end of the driving shaft is fixedly connected to a gear, and a driving seat with an arc-shaped cross-section is slidably provided on the frame along the vertical direction, the inner arc surface of the driving seat is connected to an inner gear ring, the gear is meshed with the inner gear ring, and the inner arc surface of the driving seat located inside the inner gear ring is provided with a limiting motion groove for limiting the motion of the driving shaft, and the end of the driving shaft away from the servo motor movably extends into the limiting motion groove.

[0019] By adopting the above technical solution, the servo motor drives the driving shaft to rotate, and one end of the driving shaft is always in sliding contact with the limiting motion groove, so that the gear and the inner gear ring are engaged to drive the horizontal plate to swing back and forth in the horizontal direction toward one end of the frame, thereby driving the spray gun to automatically swing in the horizontal direction.

[0020] Furthermore, a plurality of brackets are fixedly connected to the lower end of the horizontal plate, the drive shaft movably penetrates the brackets, and the drive shaft is rotatably connected to the brackets via bearings.

[0021] By adopting the above technical solution, the bracket is used to limit the rotation of the drive shaft to enable it to rotate smoothly.

[0022] Further, the horizontal plate is provided with a rectangular sliding opening, the sliding opening is provided with a supporting mechanism, the supporting mechanism includes a sliding sleeve slidably connected in the sliding opening, a support rod is provided in the sliding sleeve, a guide frame is fixedly connected to the gun body of the spray gun, a guide wheel is limitedly and rollingly connected in the guide frame, a hinge seat is connected to the lower end of the guide wheel, an upper end of the support rod passes through the sliding sleeve and is detachably connected to the hinge seat, an electric push rod is connected to the side of the sliding opening close to the muzzle of the spray gun, and an output end of the electric push rod is fixedly connected to the sliding sleeve;

[0023] A controller is installed on the top of the main body of the soil spraying machine, and the controller is connected with the electric push rod signal.

[0024] By adopting the above technical solution, when the horizontal plate drives the spray gun to swing horizontally, the controller can control the electric push rod to extend or retract at a fixed time, and the sliding sleeve drives the support rod to move synchronously when it moves horizontally in the sliding mouth, so that the guide wheel and the guide frame cooperate to drive the spray gun body to rotate, thereby automatically changing the spray angle of the spray gun and completing the soil spraying coverage of the inclined surface of the entire slope.

[0025] Furthermore, the lower end of the support rod passes through the sliding sleeve and is rotatably connected to a lifting wheel, a driving roller is eccentrically sleeved on the shaft wall of the driving shaft, and the lifting wheel is rollingly connected to the roller wall of the driving roller;

[0026] A second reset member is commonly connected between the support rod and the sliding sleeve.

[0027] By adopting the above technical solution, when the driving shaft rotates, the contact point between the driving roller and the lifting wheel changes back and forth up and down, and the second reset member drives the lifting wheel to always contact the driving roller, so that when the driving roller rotates, the lifting wheel drives the support rod to move vertically synchronously, so that the spray gun can perform a small vertical reciprocating swing during the horizontal reciprocating swing, and the muzzle end of the spray gun can move in a wave-like manner, which can help to improve the uniformity of the coverage of the imported soil on the slope.

[0028] Furthermore, the driving roller is in a truncated cone-shaped structure, and the large end of the driving roller is arranged toward the muzzle of the spraying gun.

[0029] With the above technical solution, when the electric push rod contracts and drives the support rod to move so that the spray gun reduces the spray angle, the lifting wheel moves synchronously with the support rod, and the contact point position of the lifting wheel and the driving roller changes at this time, and the up and down change amplitude of the contact point increases, thereby compensating for the reduction of the up and down swing amplitude of the spray gun at a small angle, ensuring that the spray gun sprays the same volume of foreign soil on the slope of the same area in the same unit time, further improving the spraying uniformity. The rest of the structure is the same as that of the embodiment.

[0030] Another object of the present invention is to provide a method for repairing the slope of an open-pit mine dump, the purpose of which is to automatically and evenly spray the imported soil on the slope of the open-pit mine dump.

[0031] To achieve the above object, the present invention provides the following technical solution: a method for using an open-pit mine spoil dump slope repair device, comprising the following steps:

[0032] S1. Pour soil, grass seeds, fertilizer, water, etc. into the storage tank of the main body of the guest soil sprayer in order according to the proportion, and the stirring system in the storage tank stirs and mixes them evenly to form guest soil;

[0033] S2. The conveying pump of the main body of the imported soil spraying machine conveys the imported soil into the conveying pump pipe, and sprays it onto the slope of the open-pit mine dump through the nozzle of the spraying gun;

[0034] S3, the servo motor rotates, driving the gear to move on the inner gear ring to make the horizontal plate swing back and forth horizontally, and the driving roller drives the lifting wheel to move up and down to make the muzzle of the spray gun move up and down. The muzzle of the spray gun makes a wave-like reciprocating motion, and the slope is automatically and evenly sprayed with foreign soil;

[0035] S4. The controller controls the extension and retraction of the electric push rod, drives the sliding sleeve to move, changes the nozzle angle of the spray gun, and enables the spray gun to automatically complete the spraying of the foreign soil on the entire slope.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. When the spray gun lowers its angle to spray the soil on the nearby slope, the guide wheel contacts the guide plate and drives the push sleeve, which reduces the gap between the two spoiler openings and disturbs the soil sprayed from the spray gun, changing it from a water column to a fan shape, thereby reducing the impact on the slope and achieving dispersed spraying, improving the uniformity of spraying, and reducing material waste.

[0038] 2. The automatic spraying of the spray gun can be realized through the extension and retraction of the gear, the inner gear ring and the electric push rod. At the same time, the rotation of the driving roller can make the spray gun reciprocate up and down when it reciprocates horizontally, so that the spray gun moves in a wave shape, which is beneficial to improve the spraying uniformity and coverage of the guest soil.

[0039] 3. The driving roller is set in a truncated cone shape, so that when the spray gun lowers the spray angle, the driving roller drives the lifting wheel to move up and down over a larger distance, compensating for the up and down swing amplitude of the spray gun, which can further improve the spraying uniformity of the guest soil.

[0051] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0052] Example 1, reference Figure 1-Figure 5, which is the first embodiment of the present invention, provides an open-pit mine dump slope repair equipment, including a soil-injecting machine body 1 and a seeding gun 2, a delivery pump pipe is arranged on the top of the soil-injecting machine body 1, the seeding gun 2 is sealed and rotatably connected to the output end of the delivery pump pipe, and a seeding auxiliary mechanism is arranged between the soil-injecting machine body 1 and the seeding gun 2; the seeding auxiliary mechanism includes a frame 3 fixedly connected to the top of the soil-injecting machine body 1, and a horizontal plate 4 movably connected to the top of the frame 3, one end of the horizontal plate 4 is fixedly connected to the seeding gun 2, and a pushing sleeve 5 and a positioning sleeve 6 are arranged on the gun body of the seeding gun 2 near the muzzle in sequence Sleeve 6, the pushing sleeve 5 is slidably connected to the spray gun 2, the positioning sleeve 6 is fixedly sleeved with the spray gun 2, and the pushing sleeve 5 is located between the positioning sleeve 6 and the muzzle of the spray gun 2; a spoiler assembly 7 is arranged on the pushing sleeve 5, and the spoiler assembly 7 is used to change the foreign soil spraying range of the spray gun 2; a support frame 8 is arranged on the top of the horizontal plate 4 corresponding to the position of the spray gun 2, and support plates 9 are vertically slidably connected to the two symmetrical outer walls of the support frame 8, and the upper end of the support plate 9 is hinged with the positioning sleeve 6, and inclined guide plates 11 are arranged on the two symmetrical inner walls of the support frame 8. When the pushing sleeve 5 contacts the guide plate 11, the spoiler assembly 7 is driven to retract.

[0053] Specifically, the conveying pump in the main body 1 of the foreign soil spraying machine can convey the mixed foreign soil into the conveying pump pipe, and spray the foreign soil onto the slope of the open-pit mine spoil dump through the nozzle of the spraying gun 2. As the spraying angle of the spraying gun 2 gradually decreases, the pushing sleeve 5 follows the spraying gun 2 to descend and contact the guide plate 11, and the pushing sleeve 5 moves toward the muzzle end of the spraying gun 2, which can drive the spoiler component 7 to retract, interfere with the path of the foreign soil sprayed by the spraying gun 2, and change the foreign soil originally sprayed by the spraying gun 2 from a water column shape to a fan shape, thereby reducing the scouring of soil on the slope without reducing the injection flow rate. At the same time, the foreign soil is sprayed onto the slope in a fan shape, which can prevent the foreign soil from flowing downward quickly on the slope, reduce material waste and achieve uniform coverage.

[0054] Reference Figure 3-Figure 5 The spoiler assembly 7 includes a support ring 71 fixedly sleeved on the gun body of the spray gun 2 near the muzzle, and two spoiler plates 72 are symmetrically hinged on the support ring 71. The side of the spoiler plate 72 away from the muzzle of the spray gun 2 is slidably connected to a connecting rod 73, and the other end of the connecting rod 73 is hinged to the outer wall of the pushing sleeve 5, and the outer wall of the pushing sleeve 5 is symmetrically rotatably connected to two guide wheels 10.

[0055] Specifically, the two spoilers 72 are respectively arranged on the upper and lower sides of the muzzle of the spray gun 2. When the spraying angle of the spray gun 2 is reduced, the guide wheel 10 can roll in contact with the guide plate 11, so that the push sleeve 5 moves toward the muzzle of the spray gun 2, and the spoiler 72 is driven to rotate through the connecting rod 73. When the distance between the right sides of the two spoilers 72 is smaller than the diameter range of the water column-shaped guest soil sprayed by the spray gun 2, the moving range of the sprayed guest soil can be changed to change it into a fan shape.

[0056] Reference Figure 4-Figure 5 An anti-overflow cover 74 is fixedly sleeved on the gun body at the muzzle end of the spray gun 2. The anti-overflow cover 74 is U-shaped and made of flexible rubber. The edges of the two spoilers 72 facing each other are fixedly connected to the openings on both sides of the anti-overflow cover 74.

[0057] Specifically, the anti-overflow cover 74 can shield the remaining sides of the two spoiler plates 72 to prevent part of the foreign soil from overflowing through the sides under the action of the spoiler, thereby avoiding waste of foreign soil resources.

[0058] Reference Figure 3-Figure 5 A plurality of reset members 12 are connected to the push sleeve 5 and the positioning sleeve 6 in a circular array.

[0059] Specifically, when the guide wheel 10 is not in contact with the guide plate 11, the reset member 12 can drive the pushing sleeve 5 to approach the side of the positioning sleeve 6, so that the right sides of the two spoilers 72 maintain the maximum distance, avoiding interference with the water column-shaped foreign soil sprayed by the spray gun 2, so that the spray gun 2 maintains its spraying ability and sprays foreign soil on the distant slope.

[0060] It is understandable that the reset member 12 can be a spring, an elastic rope, an elastic band, or any other object that can automatically shrink and recover after being stretched.

[0061] Example 2, reference Figure 6-Figure 8 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a swing mechanism 13 is arranged on the spraying auxiliary mechanism, and the swing mechanism 13 includes a servo motor 131 fixedly arranged through the horizontal plate 4, the output end of the servo motor 131 extends to the bottom of the horizontal plate 4, and the output end of the servo motor 131 is connected to a driving shaft 132 through a coupling, and the other end of the driving shaft 132 is fixedly connected to a gear 133, and a driving seat 134 with an arc-shaped cross section is slidably arranged on the frame 3 along the vertical direction, and an inner gear ring 135 is connected to the inner arc surface of the driving seat 134, and the gear 133 is meshed with the inner gear ring 135, and a limiting motion groove 136 for limiting the motion of the driving shaft 132 is opened on the inner arc surface of the driving seat 134 located inside the inner gear ring 135, and the end of the driving shaft 132 away from the servo motor 131 is movably extended into the limiting motion groove 136.

[0062] Specifically, the servo motor 131 drives the driving shaft 132 to rotate, and one end of the driving shaft 132 is always in sliding contact with the limiting motion groove 136, so that the gear 133 is engaged with the inner gear ring 135 to drive the horizontal plate 4 to swing back and forth in the horizontal direction toward one end of the frame 3, thereby driving the spray gun 2 to automatically swing in the horizontal direction.

[0063] Among them, the limiting movement groove 136 is a waist-shaped hole structure from the left-view plane perspective, and the inner gear ring 135 has the same shape as the limiting movement groove 136, and the cross-sectional curvature of the driving seat 134 is adapted to the swing curvature of the right end of the horizontal plate 4, so that the gear 133 can always maintain meshing with the inner gear ring 135. When the gear 133 moves in the horizontal part of the inner gear ring 135, the inner gear ring 135 is limited by the frame 3 and cannot move horizontally, and the horizontal plate 4 is forced to swing horizontally. When the gear 133 moves in the arc part of the inner gear ring 135, the inner gear ring 135 performs vertical displacement on the frame 3, thereby realizing that the gear 133 and the inner gear ring 135 cooperate to drive the horizontal plate 4 to swing back and forth horizontally.

[0064] It is understandable that, referring to Figure 6 A roller is connected to the bottom surface of the right end of the horizontal plate 4, and an arc groove is opened on the top surface of the frame 3. The frame 3 can provide support for the horizontal plate 4 through the cooperation of the roller and the arc groove, and at the same time, the movement of the horizontal plate 4 can be more stable.

[0065] Reference Figure 8 A plurality of brackets 14 are fixedly connected to the lower end of the horizontal plate 4, and a driving shaft 132 movably penetrates the bracket 14, and the driving shaft 132 is rotatably connected to the bracket 14 through a bearing.

[0066] Specifically, the bracket 14 is used to limit the rotation of the driving shaft 132 to enable it to rotate smoothly.

[0067] Reference Figure 1 and Figure 8 A rectangular sliding opening 41 is provided on the horizontal plate 4, and a supporting mechanism 15 is arranged on the sliding opening 41. The supporting mechanism 15 includes a sliding sleeve 151 slidably connected in the sliding opening 41, and a support rod 152 is arranged in the sliding sleeve 151. A guide frame 153 is fixedly connected to the gun body of the spraying gun 2, and a guide wheel 154 is limitedly and rollingly connected in the guide frame 153. The lower end of the guide wheel 154 is connected to a hinge seat 155, and the upper end of the support rod 152 passes through the sliding sleeve 151 and is detachably connected to the hinge seat 155. An electric push rod 156 is connected to the side of the sliding opening 41 close to the muzzle of the spraying gun 2, and the output end of the electric push rod 156 is fixedly connected to the sliding sleeve 151; a controller is installed on the top of the main body 1 of the soil spraying machine, and the controller is connected to the electric push rod 156 by signal.

[0068] Specifically, when the horizontal plate 4 drives the spray gun 2 to swing horizontally, the controller can control the electric push rod 156 to extend or retract at a fixed time, and the sliding sleeve 151 drives the support rod 152 to move synchronously when moving horizontally in the sliding mouth 41, so that the guide wheel 154 and the guide frame 153 cooperate to drive the gun body of the spray gun 2 to rotate, thereby automatically changing the spraying angle of the spray gun 2 and completing the soil spraying coverage of the inclined surface of the entire slope.

[0069] When the spray gun 2 is working, the controller controls the electric push rod 156 to extend or retract at fixed set time intervals, and the sliding sleeve 151 cooperates with the support rod 152 to change the angle of the spray gun 2.

[0070] Among them, refer to Fig. 9 The upper end of the support rod 152 and the lower end surface of the hinge seat 155 are both provided with locking holes, and the locking holes of the support rod 152 and the hinge seat 155 are fastened together by bolts and nuts. When the support rod 152 is not connected to the hinge seat 155, the connection between the driving mechanism 13 and the supporting mechanism 15 and the spray gun 2 can be cancelled. At this time, the spray gun 2 can be manually controlled to spray the foreign soil, ensuring applicability in complex slope environments.

[0071] It is understandable that, referring to Figure 2 The spray gun 2 includes a T-shaped tube that is sealed and rotatably connected to the delivery pump pipe, and the upper end of the T-shaped tube is symmetrically connected to curved tubes on both sides, and the right ends of the two curved tubes are sealed and fixedly connected to a nozzle, and a handle is fixedly connected between the two curved tubes. When the support rod 152 is not connected to the hinge seat 155, the movement of the spray gun 2 can be controlled by the handle. The rest of the structure is the same as that of the embodiment 1.

[0072] Example 3, reference Figure 8 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the lower end of the support rod 152 passes through the sliding sleeve 151 and is rotatably connected to the lifting wheel 157, the shaft wall of the driving shaft 132 is eccentrically sleeved with a driving roller 137, and the lifting wheel 157 is rollingly connected to the roller wall of the driving roller 137; a reset member 158 is commonly connected between the support rod 152 and the sliding sleeve 151.

[0073] Specifically, when the driving shaft 132 rotates, the contact point between the driving roller 137 and the lifting wheel 157 changes back and forth up and down, and the reset member 158 drives the lifting wheel 157 to always contact with the driving roller 137, so that when the driving roller 137 rotates, the lifting wheel 157 drives the support rod 152 to move vertically synchronously, so that the spray gun 2 can perform a small vertical reciprocating swing during the horizontal reciprocating swing, and the muzzle end of the spray gun 2 can move in a wave-like manner, which can help to improve the uniformity of the cover of the imported soil on the slope.

[0074] It is understandable that the second reset member 158 can be a spring, an elastic rope, an elastic band, or another object that can automatically shrink and recover after being stretched.

[0075] Reference Fig. 9 The driving roller 137 is in a truncated cone shape, and the large end of the driving roller 137 is arranged toward the muzzle of the spraying gun 2.

[0076] Specifically, when the electric push rod 156 contracts and drives the support rod 152 to move so that the spray gun 2 reduces the spray angle, the lifting wheel 157 moves synchronously with the support rod 152. At this time, the contact point position of the lifting wheel 157 and the driving roller 137 changes, and the up and down change amplitude of the contact point increases, thereby compensating for the reduction of the up and down swing amplitude of the spray gun 2 at a small angle, ensuring that the spray gun 2 sprays the same volume of foreign soil on the slope of the same area in the same unit time, further improving the spraying uniformity. The rest of the structure is the same as that of Example 2.

[0077] Comprehensive examples 1-3, the working principle of the present invention:

[0078] The main body 1 of the soil-injection spraying machine is moved to the side of the slope of the open-pit mine dumping ground. After the soil, grass seeds, fertilizer, water, etc. are mixed in the main body 1 of the soil-injection spraying machine, the soil-injection spraying machine is transported to the spraying gun 2 through the delivery pump. The servo motor 131 drives the driving shaft 132 and the gear 133 to rotate. The gear 133 engages with the inner gear ring 135 to drive the horizontal plate 4 to swing back and forth horizontally. At the same time, the driving roller 137 cooperates with the lifting wheel 157 to drive the muzzle end of the spraying gun 2 to reciprocate up and down, thereby causing the port of the spraying gun 2 to move in a wave shape, realizing automatic soil spraying on the slope, and the sliding sleeve 15 is driven by the electric push rod 156. 1. The movement of the support rod 152 can change the spraying angle of the spray gun 2, thereby realizing automatic spraying of the entire slope. When the spraying angle of the spray gun 2 is low, the guide wheel 10 rolls in contact with the guide plate 11, so that the push sleeve 5 moves toward the muzzle of the spray gun 2, and the spoiler 72 is driven to rotate through the connecting rod 73. When the distance between the right sides of the two spoilers 72 is smaller than the diameter range of the water column-shaped guest soil sprayed by the spray gun 2, the movement range of the sprayed guest soil can be changed to change it into a fan shape, thereby avoiding soil scouring on the nearby slope. At the same time, the fan-shaped guest soil is conducive to covering the slope and avoiding rapid downward flow.

[0079] Example 4, reference Figure 1-Figure 9 , which is a fourth embodiment of the present invention, provides a method for using a method for repairing a slope of an open-pit mine dump, comprising the following steps:

[0080] S1, pouring soil, grass seeds, fertilizer, water, etc. into the storage tank of the guest soil spraying machine body 1 in order according to the proportion, and the stirring system in the storage tank stirs and mixes them evenly to form guest soil;

[0081] S2, the delivery pump of the main body 1 of the imported soil spraying machine delivers the imported soil into the delivery pump pipe, and sprays it onto the slope of the open-pit mine dump through the nozzle of the spraying gun 2;

[0082] S3, the servo motor 131 rotates, driving the gear 133 to move on the inner gear ring 135 to make the horizontal plate 4 swing back and forth horizontally, and the driving roller 137 drives the lifting wheel 157 to move up and down to make the muzzle of the spraying gun 2 move up and down, and the muzzle of the spraying gun 2 makes a wave-like reciprocating motion, so as to automatically and evenly spray the soil on the slope surface;

[0083] S4, the controller controls the electric push rod 156 to extend and retract, driving the sliding sleeve 151 to move, changing the nozzle angle of the spray gun 2, so that the spray gun 2 automatically completes the spraying of the foreign soil on the entire slope.
