[0053] Specifically, the delivery pump in the guest soil spraying machine body 1 can deliver the mixed guest soil into the delivery pump pipe, and spray the guest soil to the slope of open pit dump through the nozzle of spraying gun 2, as the spraying angle of spraying gun 2 gradually decreases, push sleeve 5 follows spraying gun 2 and contacts with guide plate 11, push sleeve 5 moves to the muzzle end of spraying gun 2, which can drive turbulence component 7 to fold, and the path of the guest soil sprayed by spraying gun 2 is disturbed, so that the water column shape of the guest soil is changed into fan shape, without reducing the injection flow, the soil erosion on the slope surface is reduced, and the guest soil sprayed on the slope surface in fan shape can avoid flowing down quickly, reduce material waste and achieve uniform coverage.

[0058] With reference to Figures 3-5 , a plurality of reset members I 12 are connected in an annular array between the push sleeve 5 and the positioning sleeve 6.

[0059] Specifically, when the guide wheel 10 does not contact the guide plate 11, the reset member I 12 can drive the push sleeve 5 to move closer to one side of the positioning sleeve 6, so that the right sides of the two spoiler plates 72 maintain the maximum distance, avoiding interference with the water column-shaped guest soil sprayed by the spray seeding gun 2, so that the spray seeding gun 2 maintains the spraying ability and sprays the guest soil to the distant slope.

[0060] It can be understood that the reset member I 12 can be one of a spring, an elastic rope, an elastic band and the like which can automatically contract and recover after stretching.

[0062] Specifically, the servo motor 131 drives the drive shaft 132 to rotate, and the end of the drive shaft 132 is always in sliding contact with the limiting movement groove 136, so that the gear 133 is engaged with the inner tooth ring 135 to drive the horizontal plate 4 to reciprocally swing in the horizontal direction towards one end of the rack 3, thereby automatically swinging the spray seeding gun 2 in the horizontal direction.

[0063] The limiting movement groove 136 is in the shape of a waist hole in the left visual plane, and the inner tooth ring 135 is the same shape as the limiting movement groove 136.

Figure 9 The lower end of the supporting rod 152 penetrates through the sliding sleeve 151 and is rotatably connected with a jacking wheel 157, the shaft wall of the driving shaft 132 is eccentrically sleeved with a driving roller 137, and the jacking wheel 157 is rollingly connected with the roller wall of the driving roller 137. The spraying and seeding gun 2 comprises a T-shaped pipe which is sealingly and rotatably connected with the conveying pump pipe, the upper end of the T-shaped pipe is sealingly and rotatably connected with two elbow pipes on the two sides thereof in a symmetrical manner, the right ends of the two elbow pipes are sealingly and fixedly connected with a spray pipe, and the two elbow pipes are fixedly connected with a handle.

[0076] Specifically, when the electric push rod 156 retracts to drive the support rod 152 to move to reduce the spray angle of the spray seeding gun 2, the jacking wheel 157 moves synchronously with the support rod 152, at this time, the position of the contact point of the jacking wheel 157 with the driving roller 137 changes, the up-down change amplitude of the contact point increases, thereby making up for the decrease of the up-down swing amplitude of the spray seeding gun 2 at a small angle, ensuring that the spray seeding gun 2 sprays the same amount of customer soil on the same area of the slope in the same unit time, and further improving the spraying uniformity. The rest of the structure is the same as that of example 2.

[0077] In summary, the working principle of the present application is as follows:

[0078] The customer soil spraying machine body 1 is moved to the side of the slope of the open-pit dump, and after the soil, grass seeds, fertilizers, water and the like are mixed in the customer soil spraying machine body 1, the customer soil is delivered to the spray seeding gun 2 through the delivery pump. The servo motor 131 drives the driving shaft 132 and the gear 133 to rotate, the gear 133 meshes with the inner tooth ring 135 to drive the horizontal plate 4 to horizontally reciprocate, and the driving roller 137 cooperates with the jacking wheel 157 to drive the nozzle end of the spray seeding gun 2 to reciprocate up and down, thereby making the port of the spray seeding gun 2 displace in a wave shape, realizing automatic customer soil spraying on the slope. The electric push rod 156 drives the sliding sleeve 151 and the support rod 152 to move, so as to change the spray angle of the spray seeding gun 2, thereby realizing automatic spraying on the entire slope. When the spray angle of the spray seeding gun 2 is low, the guide wheel 10 and the guide plate 11 roll in contact, so as to move the push sleeve 5 to the nozzle end of the spray seeding gun 2. The connecting rod 73 drives the spoiler 72 to rotate, and when the distance between the right sides of the two spoilers 72 is smaller than the diameter range of the water column-shaped customer soil sprayed by the spray seeding gun 2, the moving range of the sprayed customer soil can be changed to a fan shape, so as to avoid soil erosion on the nearby slope, and the fan-shaped customer soil is beneficial to covering on the slope and avoiding rapid downward flow.

[0079] Example 4, refer to Figures 1-9 The present application provides a method for repairing the slope of an open-pit dump, and the use method of the method comprises the following steps:

[0080] S1, the soil, grass seeds, fertilizers, water and the like are sequentially poured into the storage tank of the customer soil spraying machine body 1 according to the proportion, and the stirring system in the storage tank stirs and mixes them uniformly to form customer soil;

[0081] S2, the delivery pump of the customer soil spraying machine body 1 delivers the customer soil to the delivery pump pipe, and sprays it on the slope of the open-pit dump through the nozzle of the spray seeding gun 2;

[0082] S3, the servo motor 131 rotates, drives the gear 133 to move on the inner tooth ring 135 to make the horizontal plate 4 horizontally reciprocate, the driving roller 137 drives the jacking wheel 157 to move up and down to make the nozzle of the spray seeding gun 2 reciprocate up and down, the nozzle of the spray seeding gun 2 reciprocates in a wave shape to automatically and uniformly spray the customer soil on the slope surface;

[0083] S4, the controller controls the electric push rod 156 to extend and retract to drive the sliding sleeve 151 to move, changes the nozzle angle of the spray seeding gun 2, and makes the spray seeding gun 2 automatically complete the customer soil spraying on the whole slope surface.
