Therefore, the transport direction of the conveyor belt is limited. And the conveyor belt can only run in a straight line, and the method is useless against the complicated current situations of horizontal and vertical corners and the like actually encountered in a construction site.
The movable soil transporting vehicle has the advantages of flexible transportation direction and capability of transporting soil from a low position to a high position. On one hand, however, the moving earth-moving vehicle needs manual participation, and the conveying efficiency is low; on the other hand, since the mobile earth-moving vehicle must have a road on which it can travel, the mobile earth-moving vehicle cannot carry out, for example, an operation of transporting the soil under the ground to the ground.
In summary, the existing soil transporting manner cannot satisfy the requirements of automation of the transporting process and flexibility of the transporting direction at the same time, and therefore, a soil transporting machine with automation of the transporting process and flexibility of the transporting direction is urgently needed.

Detailed Description
For a better understanding of the present invention, reference will now be made in detail to the present embodiments of the invention, which are illustrated in the accompanying drawings.
Example one
Referring to fig. 1 to 5, in the present embodiment, a pipe-line earth mover is provided. The pipeline earth moving machine comprises a feeding device 2, a pushing system 1 and a conveying pipeline 3, wherein the feeding device 2 and the pushing system 1 are used for injecting soil into the conveying pipeline 3, and the conveying pipeline 3 defines a moving path of the soil.
Specifically, the feeding device 2 comprises a feeding channel 21 and a feeding member 22, and the pushing system 1 comprises a pushing member 11 and a power mechanism.
Wherein, be equipped with the feed inlet on feed channel 21's the lateral wall, the feed inlet communicates with feed channel 21's inner chamber, and feeding member 22 communicates with the feed inlet on the feed channel 21, and the soil that gets into feeding member 22 is poured into feed channel 21 inner chamber from the feed inlet.
Wherein the outlet of the feeding channel 21 is communicated with the inlet of the conveying pipe 3, preferably, the outlet of the feeding channel 21 is detachably connected with the inlet of the conveying pipe 3 (for example, detachably connected by a flange), and the inner cavity of the feeding channel 21 is communicated with the inner cavity of the conveying pipe 3.
Wherein the pusher 11 is slidably arranged in the feed channel 21, the pusher 11 dividing the feed channel 21 into a front feed channel region in front thereof and a rear feed channel region in rear thereof. And the impeller 11 is arranged to prevent the soil in the front feed channel region from flowing to the rear feed channel region, i.e. the shape and size of the impeller 11 are designed to ensure that the soil in the front side of the impeller 11 does not enter the rear side of the impeller. In the present invention, the side of the pusher 11 close to the conveying pipe 3 is regarded as the front of the pusher 11, and the side of the pusher 11 far from the conveying pipe 3 is regarded as the rear of the pusher 11, that is, the conveying direction of the soil is the direction from the rear to the front.
The power mechanism is connected with the pushing piece 11 to drive the pushing piece 11 to reciprocate between two sides below the feeding hole, soil can fall into an inner cavity of the feeding channel 21 from the feeding hole when the pushing piece 11 moves backwards, and the pushing piece 11 compresses and pushes the soil below the feeding hole when the pushing piece 11 moves forwards.
Therefore, the pipeline earth moving machine of the embodiment innovatively adopts the conveying pipeline 3 to convey the soil, and adopts the reciprocating motion of the pushing piece 11 to continuously compress and push the newly injected soil, so as to push the soil in the conveying pipeline 3 to move forwards. On one hand, the power mechanism provides power for the pushing piece 11 to push the soil in the conveying pipeline 3 forwards, the conveying process does not need human participation, and the automation degree is high; on the other hand, the extension direction of the conveying pipeline 3 can be flexibly set according to the actual working condition, so that the conveying direction of the pipeline earth transporter is flexible, for example, when the soil needs to be transported to a high place from a low place, the upward transportation which cannot be realized by the conveying belt is completed by a large height, and the like. Simultaneously, the pipeline earth moving machine of this embodiment need not the walking road like the earth moving vehicle, and the pipeline earth moving machine is lower to the requirement that sets up the region, and the suitability is stronger.
In the present embodiment, the conveying pipe 3 comprises a transverse conveying section 31, an upwardly extending vertical conveying section 32 and a curved transition section 33 connected therebetween, preferably, the axis of the transverse conveying section 31 is perpendicular to the axis of the vertical conveying section 32. Thereby transporting the soil from a lower location to a higher location. Compared with the mode of conveying by a conveyor belt and a soil transporting vehicle, the pipeline soil transporting machine is particularly suitable for being arranged underground. Moreover, the whole conveying pipeline 3 can be in a linear or bent shape in the axial direction so as to adapt to a conveying path required by actual working conditions.
Of course, the pipe-line earth moving machine of the present invention can transport the earth from a lower position to a higher position, but is not limited thereto, and the transport pipe 3 can be set to have different extending directions according to different transport requirements, so as to transport the earth in different directions (including horizontal, upward and downward). Also, the pipe earth moving machine of the present invention is not limited to be disposed underground.
Further, the inner cavity of the feeding channel 21 is cylindrical, the inner cavity of the conveying pipeline 3 is also cylindrical, and the inner diameters of the feeding channel and the conveying pipeline are equal or close to each other, so that the conveying fluency of the soil is improved. Preferably, the horizontal conveying section 31 and the vertical conveying section 32 of the conveying pipeline 3 are both formed by detachably connecting a plurality of round pipes.
Further, in this embodiment, the feeding member 22 is a hopper, and an outlet of the hopper is communicated with a feeding port on a side wall of the feeding channel 21, and preferably, the hopper is integrated with the feeding channel 21, and the hopper is a trapezoidal hopper. Of course, the invention is not limited thereto, the hopper may be conical in shape, and the charging member 22 is not limited thereto.
Further, in the present embodiment, the area of the feeding channel 21 located at the rear of the pushing member 11 is communicated with the outside air (for example, one end of the feeding channel 21 far from the conveying pipe 3 is open, and a gap is formed between the part of the power mechanism inserted into the feeding channel 21 and the feeding channel 21; or an air inlet hole is provided on the side wall of the feeding channel 21, and the air inlet hole is located at the rear side of the pushing member 11 moving to the rearmost limit position). The pushing piece 11 is provided with a one-way communication mechanism, the one-way communication mechanism only allows air behind the pushing piece 11 to enter the front feeding channel area of the pushing piece 11 in the backward moving process of the pushing piece 11, and air and soil on two sides of the pushing piece 11 are not allowed to flow through the one-way communication mechanism in the forward moving process of the pushing piece 11. The advantages of the above arrangement are: after the soil is compressed and pushed, a compression area A is formed on one side, close to the pushing piece 11, of the soil, negative pressure is formed in the compression area A due to the fact that the pushing piece 11 moves like a piston, energy loss can be brought to the formation of the negative pressure, on the other hand, the soil pushed forwards is sucked backwards, forward transportation of the soil is not facilitated, and conveying efficiency is reduced. The one-way communication mechanism is arranged, so that in the process that the pushing piece 11 moves backwards, air which forms a high-pressure area (relative to the compression area A) at the rear side of the pushing piece due to the communication with outside air enters the compression area A in front of the pushing piece, the problem of negative pressure of the compression area A is solved, the energy consumption is reduced, and the conveying efficiency is improved.
Further, in the present embodiment, the one-way communication mechanism includes a gas injection hole 12 and a baffle 13, the gas injection hole 12 is disposed on the pushing member 11 and communicates with the feeding passage areas on both sides thereof, the baffle 13 is movably connected to the pushing member 11 between two positions of closing the gas injection hole 12 and opening the gas injection hole 12, and the baffle 13 is connected to the front side of the pushing member 11, that is, the connecting position of the actuating mechanism of the baffle 13 and the pushing member 11 is on the opposite side of the pushing member 11, and the direction of the above movement of the baffle 13 is parallel to the extending direction of the gas injection hole 12, wherein "parallel" is not limited to two directions being identical, but may be substantially the same. Therefore, when the pushing member 11 moves forward, the soil collides against the stopper 13 to exert a backward force on the stopper 13, and the stopper 13 moves backward to abut against the front end surface of the pushing member 11 to close the gas injection hole 12, so that neither soil nor air can pass through the gas injection hole 12. When the pushing member 11 moves backward, since the air pressure behind the pushing member 11 is higher than that in front of the pushing member, the air behind the pushing member 11 enters the air injection hole 12 to push the blocking piece 13 to move forward, the air injection hole 12 is opened, and the air in the high-pressure area enters the compression area a.
More specifically, in the present embodiment, pushing element 11 is vertically connected with sliding rod 14, where the "vertical connection" is not limited to be an included angle of 90 °, and an included angle between pushing element 11 and sliding rod 14 may be exactly 90 ° or about 90 °. The sliding rod 14 is provided with a limiting part 15, and the baffle piece 13 is slidably sleeved on a rod section of the sliding rod 14 between the pushing piece 11 and the limiting part 15, so that it can be understood that the pushing piece 11 limits a limit position of the baffle piece 13 moving backwards, and in the limit position, the baffle piece 13 is located at a position for closing the gas injection hole 12; the limiting portion 15 limits the limit position of the forward movement of the blocking sheet 13, and it can be understood that, in the practical application process, the air behind the pushing member 11 only needs to push the blocking sheet 13 a little distance away, so that the air in the high pressure region can enter the compression region a, that is, the gas injection hole 12 is considered to be opened, and the limiting portion 15 is used for preventing the blocking sheet 13 from being separated from the sliding rod 14 due to an excessively large movement distance. The sliding rod 14 may be a bolt screwed on the pushing member 11, and the head of the bolt forms the limiting portion 15.
Of course, the manner of connecting the flap 13 to the pusher 11 is not limited to this embodiment, and in other embodiments, the flap 13 may be rotatably connected to the pusher 11 between two positions of closing the gas-injection hole 12 and opening the gas-injection hole 12, that is, the flap 13 opens and closes the gas-injection hole 12 by rotating. For example, the top of the flap 13 may be rotatably connected to the pusher 11 by a hinge, or the top of the flap 13 may be riveted to the pusher 11 (the flap 13 may be deformed, and after the top end is fixed, air pushes the flap 13 to be bent, so that the gas injection hole 12 is opened).
Preferably, the plurality of gas injection holes 12 are arranged in a ring shape, and the plurality of baffles 13 are provided in one-to-one correspondence with the plurality of gas injection holes 12. Thus, arranging a plurality of small gas-injection holes 12 with respect to one large gas-injection hole 12 makes it possible to make the baffle 13 smaller in volume and more easily pushed open, and at the same time, to more effectively and quickly eliminate the negative pressure phenomenon in the compression region A.
Further, the position at which the pushing of the pusher 11 is stopped, i.e., the position of the stroke end of the pusher 11 located on the front side below the feed port, determines the position of the compression zone a. In the present embodiment, when the compression region a is located only in the feed passage 21, reinforcing ribs including a longitudinal rib 23 extending in the axial direction of the feed passage 21 and an annular rib 24 extending around the circumferential direction of the feed passage 21 are provided on the outer circumferential wall of the feed passage 21.
Of course, without being limited thereto, in other embodiments, when the portion of the conveying pipe 3 connected to the feed channel 21 is the compression zone a, the outer peripheral wall of the compression zone a is provided with reinforcing ribs including a longitudinal rib 23 extending in the axial direction of the compression zone a and an annular rib 24 extending around the circumferential direction of the compression zone a.
Further, in the present embodiment, the axial length of the pusher 11 is set to: when the pushing piece 11 moves to the stroke end point of the front side below the feeding hole, the pushing piece 11 can completely cover the feeding hole. Therefore, the pipeline earth moving machine can continuously inject soil into the feeding hole, when the pushing piece 11 moves forwards under the feeding hole, the soil can fall onto the pushing piece 11, when the pushing piece 11 returns backwards, the soil on the pushing piece 11 can fall into the conveying channel below the feeding hole, and the newly injected soil is used as the soil for the pushing piece 11 to compress and push when the pushing piece 11 moves forwards next time. Thus, if the axial length of the pusher 11 needs to be large enough so that the soil does not fall to the rear side of the pusher 11 during forward movement of the pusher 11.
Preferably, the pushing member 11 is cylindrical, the gas injection hole 12 and the baffle 13 are both arranged on the bottom of the pushing member, and the baffle 13 is connected to the outer surface of the bottom of the pushing member, that is, the surface facing the conveying pipeline 3. The pushing piece 11 is arranged in a cylindrical shape, so that the stability of the pushing piece 11 in the moving process is guaranteed, and the quality of the pushing piece 11 is reduced. More preferably, the pusher 11 is directly a piston.
Preferably, the pusher 11 has a reciprocating cycle of 10s, with uninterrupted continuous reciprocating motion.
In addition, the present invention is not limited to the above-mentioned one-way communication mechanism, and in other embodiments, there may be a gap between the pushing member 11 and the inner wall of the feeding channel 21, so that air behind the pushing member 11 enters the front feeding channel region of the pushing member 11 through the gap during the backward movement of the pushing member 11. It should be emphasized that since soil is a solid, having a much larger particle size than the gas molecules in air, the presence of a small gap between the pusher member 11 and the inner wall of the feed channel 21 is not permeable to soil, i.e., the gap is sized to not allow solid soil to pass through but air to pass through. Of course, the mode of setting the gap and the mode of setting the one-way communication mechanism can be adopted simultaneously.
Further, in the embodiment, the power mechanism comprises an extension bar 16, the extension bar 16 is used for outputting power, the free end of the extension bar 16 is connected with the pushing member 11 through a position compensation connecting piece, in the embodiment, the free end of the extension bar 16 is connected with the barrel bottom of the pushing member 11, and the connecting position and the arrangement position of the baffle 13 are located on two opposite surfaces of the barrel bottom, namely the free end of the extension bar 16 is connected with the inner surface of the barrel bottom. Therefore, the position of the extension rod 16 and the position of the pushing piece 11 do not need to be accurately aligned, the position compensation connecting piece can make up for the position error of the extension rod and the pushing piece, the installation difficulty is reduced, and the cost is further reduced.
In particular, the position-compensating connection is a pin or cardan shaft, i.e. the free end of the projecting rod 16 is connected to the pusher 11 via a pin or cardan shaft. Of course, the invention is not limited to this, and in other embodiments, the protruding rod 16 and the pushing member 11 may be fixedly connected by welding or the like.
Further, the power mechanism is a hydraulic transmission system, the hydraulic transmission system comprises a motor, a pump 17, a hydraulic jack 18, a reaction device 19, an oil tank and an oil pipe, the oil tank is connected with the hydraulic jack 18 through the oil pipe to form a loop, the pump 17 is arranged on the oil pipe, the motor is connected with the pump 17, and one end, far away from the pushing piece 11, of the hydraulic jack 18 is connected with the reaction device 19. The piston rod of the hydraulic jack 18 is the above-mentioned extension bar 16. Of course, without limitation, a hydraulic transmission system using a hydraulic cylinder may be used instead. In other embodiments, the power mechanism may also be a pneumatic transmission system, an electric push rod, a linear stepping motor, etc.
Further, the feeding device 2 further comprises a traveling mechanism 25, and the traveling mechanism 25 is fixed at the lower part of the feeding channel 21.
Further, the pushing system 1 further comprises a power cabinet, and the power cabinet is connected with the motor and used for supplying power.
