DETAILED DESCRIPTION

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.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0020] See also Figure 1 to Figure 10 In an embodiment of the present invention, a feed-assisted high-steep slope soil grassing spraying device includes: a spraying machine body 1, a filter plate 12, a stirring component, a pushing member 29 and a driving mechanism.

[0021] The sprayer body 1 is integrated with a mixing box 2, and a crushing assembly for crushing the foreign soil is arranged on the upper part of the mixing box 2, and the crushing assembly includes a crushing box 9 fixedly installed on the upper part of the mixing box 2, and a crushing body 10 is arranged in the crushing box 9, and the crushing body 10 is connected to an electric telescopic rod 11 arranged outside the mixing box 2; a discharge port 1002 is also arranged on the upper part of the crushing body 10, and the foreign soil enters the upper part of the discharge port 1002 and can enter between the crushing body 10 and the side wall of the crushing box 9; further, a first crushing surface 901 is arranged on the inner wall of the crushing box 9, and a plurality of groups of second crushing surfaces 1001 parallel to each other are arranged on the crushing body 10, and the plurality of groups of the second crushing surfaces 1001 The distance from the first crushing surface 901 is gradually shortened from top to bottom; the filter plate 12 is arranged on the upper part of the mixing box 2, and a plurality of filter holes are arranged on the filter plate 12; when in use, the guest soil to be crushed is poured into the discharge port 1002, and then the electric telescopic rod 11 is controlled to move, and the electric telescopic rod 11 can drive the crushing body 10 to reciprocate in the crushing box 9, so as to utilize the interaction force between the first crushing surface 901 and the second crushing surface 1001 to squeeze and crush the guest soil, so that the block structure in the guest soil can be broken into particles, so that the guest soil can be evenly mixed with various materials such as plant seeds, water retaining agents, adhesives, etc., and at the same time, avoid the guest soil with too large a diameter from clogging the nozzle on the sprayer body 1.

[0022] Among them, since the distance between multiple groups of second crushing surfaces 1001 and the first crushing surface 901 is gradually shortened from top to bottom, when the second crushing surface 1001 of the uppermost layer moves to the second crushing surface 1001 of the lowermost layer, it can achieve step-by-step crushing through cooperation with the first crushing surface 901. On the one hand, the particle size of the crushed guest soil can be gradually reduced, thereby meeting production needs and preventing the nozzle from being blocked during the mixed spraying process due to the large diameter of the guest soil particles. On the other hand, it can reduce the load of the electric telescopic rod 11 to a certain extent to prevent the guest soil from being directly crushed to a predetermined particle size, resulting in excessive load.

[0023] See also Figure 3~Figure 4, the stirring assembly is arranged in the mixing box 2, and the stirring assembly can stir the mixture entering the mixing box 2, wherein a circulating pump 8 is also arranged outside the mixing box 2, and the circulating pump 8 can pump the material located at the bottom of the mixing box 2 to the top of the mixing box 2; the stirring assembly includes a driving motor 3 fixedly installed on the side of the mixing box 2, and the output shaft of the driving motor 3 is connected to a rotating member 4 rotatably installed in the mixing box 2; a plurality of groups of deflection plates 5 are equidistantly arranged on the rotating member 4 at a circumferential distance, and the deflection plate 5 is connected to the mixing box 2 through an abutment structure, and when the rotating member 4 rotates, the abutment structure can drive the deflection plate 5 to deflect, and the abutment structure includes a trigger shaft 6 connected to the rotating shaft of the deflection plate 5, and the trigger shaft 6 is non-coaxial with the rotating shaft of the deflection plate 5; the abutment structure also includes abutment members 7 equidistantly arranged in the mixing box 2 at a circumferential distance, and the abutment member 7 cooperates with the trigger shaft 6 to drive the deflection plate 5 to deflect.

[0024] The crushed foreign soil can fall onto the filter plate 12 and pass through the filter hole into the mixing box 2. At this time, the driving motor 3 is controlled to work, and the rotating member 4 connected to the output shaft of the driving motor 3 makes a circular motion, thereby driving the deflection plate 5 to make a circular motion. In the initial stage of the circular motion of the deflection plate 5, under the action of the fluid resistance in the mixing box 2, the deflection plate 5 can be tangent to the concentric circle coaxial with the rotating member 4, and when the trigger shaft 6 abuts against the abutment 7, the deflection plate 5 can be driven to deflect toward the outside of the rotating member 4, and reset after the trigger shaft 6 is separated from the abutment 7, that is, the deflection plate 5 can reciprocate during the circular motion. In this process, on the one hand, the rotation of multiple groups of deflection plates 5 can be used to stir and mix the materials in the mixing box 2, thereby improving the mixing degree between the materials. On the other hand, the reciprocating deflection of the deflection plate 5 itself can increase the turbulence in the mixing box 2, thereby avoiding the precipitation of foreign soil in the mixture, thereby further improving the mixing degree between the materials.

[0025] See also Figure 5~Figure 8, the pushing members 29 are provided with multiple groups along the width direction of the filter plate 12. It should be noted that the cross section of the pushing members 29 is a diamond-shaped structure. When the pushing members 29 move, they can drive the foreign soil that falls into the filter plate 12 to move laterally. At the same time, when the foreign soil abuts against the side of the pushing members 29, a force along the width direction of the filter plate 12 can be generated. Based on the above process, it is not difficult to conclude that when the pushing members 29 push the foreign soil particles to move on the filter plate 12, they can not only move along the length direction of the filter plate 12, but also move along the width direction of the filter plate 12, so that the foreign soil can move in multiple directions on the filter plate 12. The contact probability between the foreign soil and the filter holes is improved, the filtering speed is improved, and the foreign soil particles that are still in a larger particle size after being crushed can be removed through the filtering holes; the driving mechanism is arranged on the mixing box 2 and connected to the pushing member 29, and the driving mechanism includes a transverse movement component and a lifting component. When the pushing member 29 moves to the end of the stroke, the transverse movement component can drive the pushing member 29 to move along the width direction of the filter plate 12, and the lifting component can drive the pushing member 29 to perform a lifting action; the transverse movement component includes a linear drive module 13 installed on the side of the mixing box 2, The linear drive module 13 is provided with two groups of transverse shafts 15, and transverse members 16 are slidably installed on the two groups of transverse shafts 15, and the transverse members 16 are slidably connected with the pushing members 29; the transverse movement assembly also includes a limiting structure and a trigger structure connecting the linear drive module 13 and the transverse member 16, and the limiting structure cooperates with the trigger structure to drive the pushing member 29 to move along the width direction of the filter plate 12 when the transverse member 16 moves to the end of the stroke, and the trigger structure includes a trigger plate 22 arranged on both sides of the mixing box 2, and the trigger plate 22 is provided with an inclined surface 2201, which is rotatably installed on the The trigger wheel 21 on the transverse member 16 is adapted to the inclined surface 2201; the limiting structure includes a retaining member 17 symmetrically arranged on the transverse member 16, and two groups of grooves 1701 are arranged on the retaining member 17; the limiting structure also includes a connecting frame 20 connected to the linear drive module 13, and a locking rod 18 adapted to the groove 1701 is slidably installed on the connecting frame 20, and a limiting ring 1801 is arranged at one end of the locking rod 18, and a columnar spring 19 is sleeved on the locking rod 18, one end of the columnar spring 19 is connected to the connecting frame 20, and the other end is connected to the limiting ring 1801.

[0026] In the initial state, the locking rod 18 is in one of the grooves 1701. At this time, the elastic force provided by the columnar spring 19 can stabilize the position of the retaining member 17, thereby stabilizing the position of the transverse member 16 relative to the transverse axis 15, thereby improving the stability of the push member 29 when it moves along the length direction of the filter plate 12. When the push member 29 moves to the end of the stroke, the trigger wheel 21 located in front of the push member 29 in the movement direction can abut against the inclined surface 2201 on one group of trigger plates 22. At this time, under the cooperation of the inclined surface 2201 and the trigger wheel 21, the transverse member 16 can be driven to move along the length direction of the transverse axis 15, and the locking rod 18 can be separated from the original groove 1701 and combined with another group of grooves 1701, so as to realize the transverse member 16 again. Locking, and the significance of the above arrangement is that: since multiple groups of pushing members 29 are arranged at equal intervals and there is a gap between two adjacent groups of pushing members 29, when the pushing members 29 move, some foreign soil particles are accumulated between the two adjacent groups of pushing members 29, and when the pushing members 29 move to the end of the stroke, multiple foreign soil particle belts can be formed on the filter plate 12, and the movement distance of the transverse moving member 16 along the transverse axis 15 is half of the width of the pushing member 29, so that after the position is switched, the middle position of the pushing member 29 can be directly opposite to the middle of the gap between the two adjacent pushing members 29, and when the pushing member 29 moves in the reverse direction, it can drive the foreign soil particle belt to move in the reverse direction, so that this part of the foreign soil particles can pass through the filter hole, thereby improving the overall filtering effect of the foreign soil.

[0027] Through the above-mentioned arrangement, the movement of the pushing member 29 can drive the foreign soil particles to move along the length and width directions of the filter plate 12, and make the foreign soil particles have a tendency to roll in multiple directions. Under this tendency, the contact probability between the foreign soil particles and the filter holes can be increased to improve the filtering effect, and when the pushing member 29 moves in the reverse direction, the position of the pushing member 29 can be switched, so that when it moves in the reverse direction, it can push the foreign soil particles to move in the reverse direction, so that this part of the foreign soil particles can pass through the filter holes, thereby improving the overall filtering effect of the foreign soil.

[0028] See also Figure 5 , Figure 7~Figure 9The lifting assembly includes a follower 14 connected to the linear drive module 13, and the follower 14 is also provided with a slide groove 1401. A slider 25 is slidably installed in the slide groove 1401, and the slider 25 is also connected to a connecting shaft 24. The connecting sleeve 23 fixedly connected to the pushing member 29 can slide on the connecting shaft 24; the lifting assembly also includes a jacking kit arranged on the mixing box 2, and the jacking kit is adapted to the convex shaft 26 connected to the slider 25. The jacking kit includes a guide member 27 fixedly installed on the mixing box 2, and a guide surface 2702 is provided on the guide member 27, and a deflection member 28 is rotatably installed on the guide member 27; the end of the deflection member 28 away from the guide member 27 is located at the lower part of the rotating shaft of the convex shaft 26; the guide member 27 is also provided with an abutment portion 2701, and the abutment portion 2701 is adapted to the side wall of the deflection member 28.

[0029] When the pushing member 29 moves to the end of the stroke, the cam 26 will also abut the deflection member 28. At this time, since the end of the deflection member 28 away from the guide member 27 is at the lower part of the rotating shaft of the cam 26, and the side wall of the deflection member 28 abuts against the abutment portion 2701, the cam 26 can enter the guide member 27 through the guidance of the deflection member 28 and move through the guide surface 2702. At this time, the cam 26 drives the pushing member 29 to move upward through the slider 25, the connecting shaft 24 and the connecting sleeve 23, so that the pushing member 29 can be separated from the filter plate 12, and when the cam 26 moves to the end of the guide member 27 away from the deflection member 28, the pushing member 29 will be reset under the action of gravity, and at the same time, the pushing member 29 switches to the other side of the foreign soil particle belt, and cooperates with the position switching of the pushing member 29, so that when the pushing member 29 moves in the reverse direction, it can drive the foreign soil particle belt to move in the reverse direction.

[0030] Furthermore, when the pushing member 29 moves in the reverse direction and the convex shaft 26 abuts against the deflection member 28 again, the deflection member 28 can deflect upward, and after the deflection member 28 is separated from the convex shaft 26, the deflection member 28 can automatically reset under the action of gravity.

[0031] Through the above arrangement, when the pushing member 29 moves to the end of the stroke, it can also perform a lifting action and switch from one side of the foreign soil to the other side, so that when the pushing member 29 moves in the reverse direction, it can also drive the foreign soil particles to move in the reverse direction, thereby driving the foreign soil particles to move in the reverse direction, further increasing the rate at which the foreign soil particles pass through the filter holes.

[0032] The spraying method of the high steep slope soil grassing spraying device based on feed-assisted spraying comprises the following steps: Step 1: dump the foreign soil into the crushing assembly, and the crushing assembly crushes the foreign soil, and the crushed foreign soil falls onto the filter plate 12; Step 2: Control the driving mechanism to drive the pusher 29 to move along the length direction of the filter plate 12, so that the foreign soil particles can pass through the filter holes; Step 3: When the push member 29 moves to the end of the stroke, the push member 29 can move along the width direction of the filter plate 12, and at the same time, the push member 29 performs a lifting action to move to the other side of the foreign soil, so that when the push member 29 moves in the reverse direction, it can continue to drive the foreign soil to move; Step 4: Control the stirring component to stir the mixture entering the mixing box 2; Step 5: Start the spraying machine body 1 and start spraying.
