the conveying belt 1 is used for conveying soil, and side baffles 1-1 are arranged on two sides of the conveying belt 1.
Specifically, soil falls into the conveyor belt 1 from the upstream end of the conveyor belt 1, and leaves the conveyor belt 1 from the downstream end of the conveyor belt 1, and enters the next stirring and mixing process. The side guards 1-1 serve to prevent soil on the conveyor belt 1 from laterally escaping the conveyor belt 1 and cooperate with the conveyor belt 1 to confine the soil in an area above the belt face of the conveyor belt 1.
The first and second flow dividing portions 2-1 and 2-2 each have a first end and two second ends extending from the first end to both sides downstream; an arc-shaped flow dividing surface 2-3 is formed between the first end and the two second ends, and the bottom ends of the flow dividing surfaces 2-3 are inserted into soil.
Specifically, the first diversion part 2-1 and the second diversion part 2-2 are fixed at a preset position, the conveying belt 1 carries soil to sequentially pass through the first diversion part 2-1 and the second diversion part 2-2, and in the process, the diversion surface 2-3 pushes the soil to two sides along the trend of the diversion surface 2-3 from the first end. At this time, after the soil passes through the first and second diverting portions 2-1 and 2-2, first and second grooves G1 and G2, which are flush with the first and second diverting portions 2-1 and 2-2, respectively, are formed. While the soil at both sides of the trench is limited by the side dams 1-1, the soil thickness at that location will increase.
Meanwhile, the part of the soil at the bottom of the groove is in an initial state, so that the soil is in an upper layer and a lower layer in the thickness direction.
The first spraying part 3-1, the second spraying part 3-2 and the third spraying part 3-3, wherein the first spraying part 3-1 is arranged in a first groove G1 formed after soil passes through the first diversion part 2-1, the second spraying part 3-2 is arranged in a second groove G2 formed after soil passes through the second diversion part 2-2, and the third spraying part 3-3 is arranged above the soil on two sides of the first groove G1 and the second groove G2.
Specifically, the first spray portion 3-1 and the second spray portion 3-2 spray the soil directly in the trench, which can spray directly to the surface of the soil under the soil in the trench range and the soil corresponding to both side inner wall portions of the trench. And the third spraying part 3-3 sprays corresponding to the soil surface at both sides of the groove.
By adopting the spraying mode, firstly, the first spraying part 3-1 and the second spraying part 3-2 can spray the soil, and secondly, the third spraying part 3-3 can directly spray the soil surface layer. The first spraying part 3-1, the second spraying part 3-2, the third spraying part 3-3, the first groove G1, the second groove G2 and the side baffle 1-1 are matched, so that the mixing efficiency of the environment-friendly repairing agent and soil is higher.
The first flow dividing parts 2-1 and the second flow dividing parts 2-2 are distributed on the conveying belt 1 in an upstream-downstream mode, the two first flow dividing parts 2-1 are distributed in parallel in the width direction of the conveying belt 1, and the second flow dividing parts 2-2 are located in the middle position between the two first flow dividing parts 2-1 in the width direction of the conveying belt 1.
Specifically, after the first and second diverting portions 2-1 and 2-2 are disposed as described above, when soil enters the second diverting portion 2-2, the soil between the two first grooves G1 is divided into two portions by the second diverting portion 2-2 and is guided to both sides by the two diverting surfaces 2-3 of the second diverting portion, respectively. In this process, the portion of the soil corresponding to the first trench G1 is refilled and surface spraying is performed after the backfilling. The soil between the two first grooves G1 is formed into second grooves G2 by the second flow dividing portion 2-2, and is sprayed in the grooves.
Through the mode that sprays in the groove, environmental protection repairing agent can spray the surface of lower floor's soil directly, and the environmental protection repairing agent of being convenient for more permeates whole soil horizon in thickness direction. Meanwhile, the interior of the upper soil is sprayed when spraying in the groove, so that the contact effect of the environment-friendly repairing agent and the upper soil in the spraying process is better, and the mixing effect of the soil and the environment-friendly repairing agent is improved. In addition, utilize the inslot to spray and combine the soil top layer to spray, on the one hand can make environmental protection repairing agent cover all soil in the whole width direction of conveyer belt 1, on the other hand the environmental protection repairing agent that the soil top layer sprayed can permeate upper soil after spraying, and then combine the inslot to spray, improve the effect that environmental protection repairing agent just permeated soil in the thickness direction. In addition, the combination of the displacement and movement effect of the upper soil in the width direction generated in the whole process of passing through the first diversion part 2-1 and the second diversion part 2-2 further improves the mixing effect of the environment-friendly restoration agent and the soil.
The top of the diversion surface 2-3 is an arc surface extending outwards from the bottom of the diversion surface, the top of the diversion surface is located outside the soil, and the top of the first end of the diversion surface 2-3 is an arc structure extending upwards from the bottom of the diversion surface.
Specifically, in the process that the soil passes through the first and second diverting portions 2-1 and 2-2, the first ends of the first and second diverting portions 2-1 and 2-2 cut the soil and guide the cut soil to the outside by the diverting surface 2-3. Meanwhile, in the process of guiding the soil, the top end of the diversion surface 2-3 is in an outwards turned arc-shaped structure relative to the bottom end, so that the soil is better pressed, and the soil is better gathered. In addition, the top of the first end of the diversion surface 2-3 is in an arc-shaped structure which is turned outwards upwards relative to the bottom of the diversion surface, so that soil is better pressed when the soil is cut, and a better cutting diversion effect on the soil is achieved. In addition, in the upper soil divided by the dividing surfaces 2-3, the width of the top is smaller than that of the bottom, so that the soil at the top can be prevented from falling off, and the forming effect of the first groove G1 and the second groove G2 is improved.
The second ends of the first flow dividing portion 2-1 and the second flow dividing portion 2-2 extend downstream to form a shielding portion 4 parallel to the side baffle plate 1-1.

Further, a converging portion 5 is disposed between the downstream ends of the two shielding portions 4 corresponding to each of the first flow dividing portions 2-1, the downstream end of the converging portion 5 is located in the middle of the two upstream ends of the conveyor belt 1 in the width direction, and an arc-shaped converging surface 5-1 is formed between the upstream end and the two downstream ends of the converging portion 5.
Specifically, the converging portion 5 is used for guiding the soil in the process of being split by the second splitting portion 2-2 after the soil passes through the shielding plate on the first splitting portion 2-1, so that the soil on both sides of the first trench G1 is converged together and enters both side regions of the second splitting portion 2-2. Meanwhile, the confluence part 5 also plays a role in forming triangular supports on the downstream ends of the two shielding parts 4 so as to improve stability of the shielding parts, and limit and guide upper soil on two sides of the first groove G1 better.
Furthermore, the two opposite converging surfaces 5-1 of the converging portions 5 are disposed corresponding to the two diverging surfaces 2-3 of the second diverging portion 2-2, respectively. After the arrangement is made, the converging surface 5-1 is matched with the flow dividing surface 2-3 of the second flow dividing part 2-2, the morphology of soil between the flow dividing surface 2-3 of the second flow dividing part 2-2 and the corresponding converging surface 5-1 is changed, the first groove G1 is continuously backfilled, and in the process, the backfilled soil is better mixed with the environment-friendly restoration liquid sprayed by the first spraying part 3-1. Meanwhile, the second flow dividing part 2-2 enables the soil to form a second groove G2, the position of the second groove G2 is matched with the position of the first groove G1, the soil is better covered in the width direction of the conveying belt 1, and the covering effect on spraying in a soil groove is improved. So as to improve the mixing effect of the environment-friendly restoration agent and the soil. In particular, under the action of the second flow dividing part 2-2 and the converging part 5, the soil can displace and move in the width direction of the conveyor belt 1, and the soil can be more fully mixed with the environment-friendly restoration agent sprayed by the first spraying part 3-1 and the third spraying part 3-3 corresponding to the first spraying part 3-1.
The two sides of the second flow dividing part 2-2 are respectively provided with a flow guiding part 6, the flow guiding parts 6 are positioned between the first flow dividing part 2-1 and the side baffle plates 1-1 in the width direction, the flow guiding parts 6 comprise a first part 6-1 which is parallel to the shielding part 4 and is arranged in a matching way, and a second part 6-2 which extends from the first part 6-1 to the upstream direction, the upstream end of the second part 6-2 is connected to the side baffle plates 1-1, the second part 6-2 is arranged corresponding to two opposite converging surfaces 5-1 in the converging parts 5, and the second part 6-2 and the converging surfaces 5-1 are arranged in a matching way in the height direction.
After passing through the second part 6-2, the soil forms a third groove G3 between the first part 6-1 and the side baffle 1-1, and a fourth spraying part 3-4 which is arranged in a matching manner with the first spraying part 3-1 and the second spraying part 3-2 is arranged in the third groove G3.
Specifically, the diversion parts 6 are matched with the second diversion parts 2-2 to guide the upper soil positioned at two sides of the first groove G1 to a position between the two diversion parts 6 and the opposite sides of the second separation part; on the one hand, the upper soil on two sides of the first groove G1 can be sprayed in the groove by forming a third groove G3 and arranging a fourth spraying part 3-4; on the other hand, three upper soil areas divided by the two first diversion portions 2-1 can be guided, and when the first trench G1 is backfilled, half of the upper soil outside the first trench G1 is backfilled by the upper soil matching between the two first trenches G1. At this time, all upper soil layers in the width direction of the conveying belt 1 are enabled to send movement, the contact effect of the environment-friendly repairing agent and the soil is improved, and meanwhile, the infiltration effect of the environment-friendly repairing agent is improved by utilizing the movement of the soil.

Specifically, the first cover 7-1 and the second cover 7-2 prevent the soil from being excessively deposited when the soil is split by the first split portion 2-1 and the second split portion 2-2. Meanwhile, the top of the shunted soil can be smoothed out. In addition, the smoothed soil is stable, and the formed stability of the first groove G1 and the second groove G2 is improved. The first split portion 2-1, the shielding portion 4, the converging portion 5, the second split portion 2-2, and the flow guiding portion 6 are fixed to the first cover 7-1 and the second cover 7-2, respectively.

The surface of the conveyer belt 1 is provided with pushing plates 1-3 at equal intervals, and the pushing plates 1-3 are positioned in the soil at the lower layer and are used for better conveying the soil. When the pushing plate 1-3 is positioned on the top belt surface of the conveyor belt 1, the pushing plate 1-3 is positioned in the lower soil and below the first and second diverting portions 2-1 and 2 in the height direction. The pushing plate 1-3 can prevent the lower soil from stagnating caused by the resistance formed when the first diversion part 2-1 and the second diversion part 2-2 divert the upper soil, ensure that the soil is effectively conveyed, and obtain the effect of being well sprayed with the environment-friendly repairing agent. Meanwhile, due to the fact that the pushing plate 1-3 is matched with the limiting effect of the side baffle plate 1-1 on the lower layer soil, when the upper layer soil is shunted, the lower layer soil can keep good integrity, and therefore the lower layer soil is better contacted and permeated by the environment-friendly repairing agent.
A feed hopper 1-2 is arranged above the upstream end of the conveyor belt 1, and materials fall onto the conveyor belt 1 from the feed hopper 1-2.
The feeder 8 comprises a transmission belt and feeding plates 8-1 fixed on the transmission belt, and the distance between two adjacent feeding plates 8-1 is the same as the distance between two adjacent pushing plates 1-3 on the transmission belt 1. Wherein the soil spreading plate 8-2 is fixed on the feeding plate 8-1 of the feeder 8 corresponding to the first diverting part 2-1. The soil spreading plate 8-2 is arranged on one side surface of the downstream of the feeding plate 8-1 in the rotation direction of the transmission belt, two soil spreading plates 8-2 are arranged in the length direction of the feeding plate 8-1, the two soil spreading plates 8-2 are oppositely arranged, and the distance between the inner side end of the soil spreading plate 8-2 and the feeding plate 8-1 is larger than the distance between the outer side end of the soil spreading plate 8-2 and the feeding plate 8-1, so that the soil spreading plate 8-2 is obliquely arranged in the length direction of the soil spreading plate; at the same time, the spreading plate 8-2 is also arranged in its height direction so as to be inclined forward with respect to its bottom end. The soil spreading plate 8-2 is used for spreading upper soil so that the soil passes through the first diversion part 2-1 more uniformly, and meanwhile, the soil pushing function is also realized.
The first spraying part 3-1, the second spraying part 3-2 and the third spraying part 3-3 are respectively provided with a group corresponding to the first flow dividing part 2-1 and the second flow dividing part 2-2 and are jointly installed on the spraying pipeline, and the fourth spraying part 3-4 is also installed on the spraying pipeline corresponding to the second flow dividing part 2-2.
