Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete spraying devices, in particular to a concrete feeding and spraying device. BACKGROUND

[0002] In related art, in the process of medium and large coal mine roadway supporting and spraying operation, the sprayed concrete is mixed and matched at the ground mixing station, and then transported to the spraying operation site by a self-unloading transport vehicle, and then manually or automatically fed to the spraying device.

[0003] At present, the automatic feeder for feeding the spraying device usually has a bin body for storing concrete, and can feed the concrete by turning the posture of the bin body. For example, Chinese patent application CN221144455U discloses a wet spraying machine with stirring, which discloses that the top edge of one side of the feeding hopper is hinged to the top edge of the stirring bin, and a turnover oil cylinder is connected between the bottom of the side of the feeding hopper and the stirring bin; when the turnover oil cylinder is elongated, it can drive the feeding hopper to turn in the direction of the stirring bin, thereby pouring the material into the stirring bin. In this arrangement, after the bin body completes a turnover and unloading, it must be reset and reloaded before the next feeding operation can be performed, and the volume of concrete that can be transported by the bin body in a single turnover is limited, resulting in low overall feeding efficiency, which affects the efficiency of the spraying operation of the spraying device. SUMMARY

[0004] In view of the above deficiencies in the prior art, the present application aims to provide a concrete feeding and spraying device to improve the feeding efficiency of the concrete feeding and spraying device.

[0005] To achieve the above-mentioned purpose, the present application provides a concrete feeding and spraying device, comprising: a machine body; a spraying device provided in the machine body and having a feeding port; a storage device comprising a storage bin provided on one side of the machine body, the storage bin having a storage tank for storing concrete, one end of the storage bin being provided with a discharge port communicating with the storage tank; a conveying device comprising a circulating conveying belt, one end of the conveying belt being provided in the machine body and being in butt joint with the feeding port, the other end of the conveying belt passing through the discharge port and extending above the tank bottom of the storage tank and being fixedly connected with the storage tank; and A material gathering device includes at least one material gathering mechanism, which includes a material gathering plate.

[0008] In one embodiment, the material gathering mechanism further includes a side plate disposed on the top side of the movable end, the side plate being able to abut against the side wall of the storage trough and being able to move toward the conveyor belt along with the material gathering plate.

[0009] In one embodiment, the storage tank extends through the end of the storage bin away from the discharge port.

[0010] In one embodiment, the shotcrete device and the storage bin are arranged at intervals along a first direction, the top of the shotcrete device is provided with the feed inlet, the height of the feed inlet in a second direction is greater than the height of the discharge outlet, the first direction and the second direction are perpendicular to each other, and the second direction is parallel to the vertical direction; The conveyor belt includes a first transport section and a second transport section connected in sequence. One end of the first transport section is located above the feed inlet, and the other end extends downward toward the storage bin in the first direction. One end of the second transport section is located outside the discharge outlet and is connected to the first transport section. The other end of the second transport section extends into and is fixed in the storage trough through the discharge outlet. The first transport section can rotate up and down around its end facing the feed inlet to drive the second transport section and the storage bin to move up and down.

[0011] In one embodiment, the conveying device further includes: A conveyor frame is movably disposed between the shotcrete device and the storage silo. One end of the conveyor support is rotatably mounted on the machine body facing the shotcrete device, and the other end is fixedly connected to the storage silo. The conveyor frame also has a through-groove at both ends, and the first transport section is disposed within the through-groove. A lifting mechanism is provided on the machine body and hinged to the second end. The lifting mechanism can drive the second end to rotate the storage bin up and down around the first end.

[0012] In one embodiment, the conveying device further includes a steering assembly, the steering assembly comprising: A steering wheel, the central axis of which extends along a third direction and is rotatably disposed outside the discharge port, the third direction being perpendicular to both the first and second directions, the conveyor belt being sleeved on the steering wheel, the steering wheel being used to guide the conveyor belt's transmission direction to divide the conveyor belt into a first transport section and a second transport section; and At least two pressure rollers are provided above the conveyor belt and abut against the top surface of the conveyor belt. The at least two pressure rollers are respectively provided on opposite sides of the discharge port in the third direction.

[0013] In one embodiment, the conveying device further includes a baffle assembly, which includes at least two baffle plates. The at least two baffle plates are spaced apart in the third direction. One end of each baffle plate is fixedly disposed on the top side of the first conveying section, and the other end extends to the top side of the second conveying section and extends between at least two pressure rollers.

[0015] This invention provides a concrete feeding and spraying equipment, which has the following advantages compared with the prior art: The conveying device of the concrete feeding and shotcreting equipment of this invention includes a circulating conveyor belt. One end of the conveyor belt can connect with the inlet of the shotcreting device, and the other end can pass through the outlet of the storage silo and extend into the storage tank inside the storage silo. Compared with the scheme of intermittently feeding the shotcreting device by flipping the silo body to alternate between flipping unloading and resetting loading postures, the storage silo of this concrete feeding and shotcreting equipment does not need to move relative to the shotcreting device. Instead, it can form a conveying path that can circulate between the shotcreting device and the storage silo by using the conveyor belt extending into the storage tank. This allows the concrete material in the storage tank to be continuously transported to the shotcreting device by the conveyor belt, thereby improving the feeding efficiency of the concrete feeding and shotcreting equipment.

[0016] Furthermore, this concrete feeding and spraying equipment also has at least one material gathering mechanism installed within the storage tank. The material gathering plate of the material gathering mechanism can be laid flat above the bottom of the storage tank together with the conveyor belt, thereby cooperating to carry all the concrete material entering the storage tank. In addition, the material gathering plate can also be flipped towards the conveyor belt to guide the concrete material on the material gathering plate to move towards the conveyor belt, so that the concrete material in the storage tank is gathered on the conveyor belt. This allows the concrete feeding and spraying equipment to transport as much concrete material in the storage tank as possible to the spraying device through the cooperation of the material gathering device and the conveyor belt, further ensuring the carrying capacity of the conveyor belt for the concrete material in the storage device.

Detailed Implementation

[0019] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0020] It should be understood that the terms "before," "after," etc., are used in this invention to describe various types of information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, "before" information can also be called "after" information, and "after" information can also be called "before" information, without departing from the scope of this invention.

[0021] like Figures 1 to 2As shown, a concrete feeding and spraying equipment 100 according to an embodiment of the present invention includes a body 10, a spraying device 30, a storage device 40, a conveying device 20, and a material gathering device 50. The spraying device 30 is located on the body 10 and has a feed inlet. The storage device 40 includes a storage bin 41 located on one side of the body, the storage bin 41 having a storage trough 411 for storing concrete material, and a discharge port 412 communicating with the storage trough 411 at one end of the storage bin 41. The conveying device 20 includes a circulating conveyor belt 21, one end of which is located on the body and connected to the feed inlet, and the other end of which passes through the discharge port. 412, and extends above the bottom of the storage trough 411, and is fixedly connected to the storage trough 411; the material gathering device 50 includes at least one material gathering mechanism 51, the material gathering mechanism 51 includes a material gathering plate 511, the material gathering plate 511 is movably arranged in the storage trough 411, at least one material gathering plate 511 is arranged in parallel with a portion of the conveyor belt 21 extending into the storage trough 411, so as to be laid flat above the bottom of the storage trough 411, and each material gathering plate 511 can be flipped toward the conveyor belt 21 to guide the concrete material on the material gathering plate 511 toward the conveyor belt 21, so that the concrete material in the storage trough 411 gathers on the conveyor belt 21.

[0022] Optionally, the bottom of the machine body 10 may be equipped with a walking device, which may be a track or a set of wheels, etc., and may be driven by a hydraulic drive device to enable the concrete feeding and spraying equipment 100 to move flexibly relative to the ground. A storage trough 411 is formed inside the storage bin 41. After the sprayed concrete material is mixed according to the specified ratio, it can enter the storage trough 411 through the opening at the top of the storage trough 411. The spraying device 30 may be configured as a rotor-type spraying machine, which can receive the concrete material conveyed to it from the storage bin 41 by the conveying device 20 and use it to spray concrete outwards. The conveying device 20 may be configured as a belt conveyor line, which may consist of a single conveyor belt 21 and can continuously convey the concrete material from its inlet end 212a to its outlet end 211a; in other embodiments, the conveying device 20 may also be formed by multiple belt conveyor mechanisms connected sequentially. Specific implementation methods can be set according to actual needs and are not limited here.

[0023] In some embodiments, the concrete feeding and shotcreting equipment 100 of this invention is further provided with a negative pressure dust collector, a cable reel device, a quick-setting agent addition device, an electromagnetic starter, and an electrical control system. The negative pressure dust collector is used to operate synchronously during the shotcreting operation of the shotcreting device 30 to remove dust, thereby helping to purify the environment of the construction site; the cable reel device includes a drive motor and a reel, the drive motor can drive the reel to rotate in a forward or reverse direction to reel in and unwind the cable, and the quick-setting agent addition device is used to add quick-setting agent.

[0024] Furthermore, the storage tank 411 is provided with a material gathering mechanism 51. The material gathering plate 511 of the material gathering mechanism 51 can move toward the conveyor belt 21 by flipping, so that the concrete material stored in the storage tank 411 is gathered onto the conveyor belt 21 and further transported by the conveyor belt 21 to its discharge end 211a, so as to enter the shotcrete device 30 through the discharge end 211a of the conveying device 20.

[0025] Understandably, compared to existing solutions that use a rotating hopper to alternate between unloading and reloading, thus intermittently feeding the shotcrete device 30, the storage hopper 41 of this concrete feeding shotcrete equipment 100 does not need to move relative to the shotcrete device 30. Instead, it can utilize the conveyor belt 21 extending into the storage tank 411 to form a conveying path that can circulate between the shotcrete device 30 and the storage hopper 41. This allows the conveyor belt 21 to continuously transport the concrete material in the storage tank 411 to the shotcrete device 30, thereby improving the feeding efficiency of the concrete feeding shotcrete equipment 100.

[0026] Furthermore, the concrete feeding and spraying equipment 100 also has at least one material gathering mechanism 51 movably installed in the storage tank 411. The material gathering plate 511 of the material gathering mechanism 51 can be laid flat above the bottom of the storage tank 411 together with the conveyor belt 21, so as to jointly carry all the concrete material entering the storage tank 411. In addition, the material gathering plate 511 can also be flipped towards the conveyor belt 21 to guide the concrete material on the material gathering plate 511 to move towards the conveyor belt 21, so that the concrete material in the storage tank 411 is gathered on the conveyor belt 21. This allows the concrete feeding and spraying equipment 100 to transport the concrete material in the storage tank 411 to the spraying device 30 as much as possible through the cooperation of the material gathering device 50 and the conveyor belt 21, further ensuring the carrying capacity of the conveyor belt 21 for the concrete material in the storage device 40.

[0027] like Figure 1 , Figure 3 as well as Figure 4 As shown, the conveyor belt 21 extends to the end of the storage trough 411 away from the discharge port 412. At least one material gathering plate 511 is provided on each of the opposite sides of the conveyor belt 21. The material gathering plate 511 has a connecting end and a movable end. The connecting end is rotatably disposed on the side of the conveyor belt 21, and the top surface of the material gathering plate 511 can be flush with the top surface of the conveyor belt 21. The material gathering mechanism 51 also includes a driving member 512, which is disposed on the bottom side of the material gathering plate 511 and connected to the movable end to drive the movable end to rotate up and down around the connecting end.

[0028] Specifically, in this embodiment, the material gathering plates 511 of the two material gathering mechanisms 51 and the portions of the conveyor belt 21 extending into the storage trough 411 both extend along the first direction, and the two material gathering plates 511 are respectively disposed on opposite sides of the first conveying section in the third direction. By extending the portion of the conveyor belt 21 into the storage trough 411 in the first direction to the end of the storage trough 411 away from the discharge port 412, the conveyor belt 21 can fully contact the concrete material entering the storage trough 411, and the concrete material can be continuously conveyed in the storage trough 411. Furthermore, the two side walls of the storage trough 411 are spaced apart from the conveyor belt 21 on both sides in the third direction, which allows the storage trough 411 to have a larger capacity. On this basis, each side wall of the storage trough 411 is provided with at least one material gathering mechanism 51 between it and the conveyor belt 21. With this arrangement, the material gathering plates 511 of the multiple material gathering mechanisms 51 can work together with the conveyor belt 21 to flatten the bottom of the storage trough 411, so that a portion of the concrete material entering the storage trough 411 can fall directly onto the conveyor belt 21.

[0029] Furthermore, a driving member 512 is provided between the material gathering plate 511 and the bottom of the storage trough 411. The bottom of the driving member 512 is fixedly connected to the bottom of the storage trough 411, and the output end of the driving member 512 is hinged to the material gathering plate 511. With this configuration, driven by the driving member 512, the material gathering plates 511 of the two material gathering mechanisms 51 can rotate from a state where they are flush with the top surface of the first conveying part to a state where they are inclined relative to the top surface of the first conveying part. This allows the concrete material located on both sides of the feed end 212a in the storage trough 411 to be gathered to the feed end 212a in the middle of the storage trough 411, so that the concrete material entering the storage trough 411 can be conveyed to the shotcrete device 30 via the conveyor belt 21 as much as possible.

[0030] The material gathering mechanisms 51, located on both sides of the conveyor belt 21, can simultaneously rotate toward the conveyor belt 21, so that the concrete material on both sides of the conveyor belt 21 gathers onto the conveyor belt 21 at the same time. Alternatively, the material gathering mechanisms 51 located on both sides of the conveyor belt 21 can also rotate alternately toward the conveyor belt 21. This allows for the continuous pouring of concrete material onto the conveyor belt 21 through the alternating operation of the two material gathering mechanisms 51, which is beneficial for the continuous feeding of concrete material from the conveyor belt 21 to the shotcrete device 30. At the same time, it can also avoid the situation where the concrete material on the conveyor belt 21 accumulates excessively due to the simultaneous rotation of the two material gathering mechanisms 51.

[0031] like Figure 4As shown, the material gathering plate 511 of this embodiment includes a base plate 511a and a connecting plate 511b. The base plate 511a is movably disposed in the material storage tank 411 and spaced apart on one side of the conveyor belt 21. The driving member 512 is telescopically disposed on the bottom side of the base plate 511a and hinged to the base plate 511a. One end of the connecting plate 511b is located on the top side of the base plate 511a and is connected to the base plate 511a through a flexible connector 511c. The other end of the connecting plate 511b protrudes toward the conveyor belt 21 and is connected to the top of the side of the conveyor belt 21.

[0032] Specifically, both the base plate 511a and the connecting plate 511b can be made of steel. The flexible connector 511c can be specifically configured as a connecting rubber plate, the two ends of which can be detachably connected to the base plate 511a and the connecting plate 511b respectively by bolts. The connecting plate 511b can be fitted to the top side of the base plate 511a and serve as an extension of the base plate 511a toward the conveyor belt 21, so that the end of the material gathering plate 511 can be connected and aligned with the top side of the conveyor belt 21, and the two can work together to bear the concrete material. Furthermore, since the connecting plate 511b is connected to the base plate 511a via the connecting rubber plate, the connecting rubber plate can have both flexible and elastic connection functions. This allows it to undergo elastic deformation when the connecting plate 511b comes into contact with the side of an external structure such as the conveyor belt 21, causing the connecting plate 511b to fold at a certain angle relative to the base plate 511a. This ensures that the connecting plate 511b remains aligned with the side of the conveyor belt 21 during folding, without causing damage to the conveyor belt 21 or the connecting plate 511b.

[0033] like Figure 4 As shown, the material gathering mechanism 51 of this embodiment of the invention also includes a side plate 513 disposed on the top side of the movable end. The side plate 513 can abut against the side wall of the material storage trough 411 and can move towards the conveyor belt 21 along with the material gathering plate 511. With this configuration, the side plate 513 can prevent the concrete material on the material gathering plate 511 from tilting towards the end of the material gathering plate 511 away from the conveyor belt 21 when it is flipped, so as to ensure the gathering effect of the material gathering mechanism 51 on the concrete material.

[0034] like Figure 1 As shown, in this embodiment of the invention, the storage trough 411 extends through the end of the storage bin 41 away from the discharge port 412. By making the storage trough 411 extend through the side of the storage bin 41 away from the discharge port 412, the top and one side of the storage bin 41 can be open, thus facilitating the direct unloading of concrete material into the storage trough 411 by dump trucks.

[0035] like Figure 1 , Figure 2 as well as Figure 8As shown, in this embodiment of the invention, the shotcrete device 30 and the storage bin 41 are arranged at intervals along a first direction. The top of the shotcrete device 30 is provided with a feed inlet. The height of the feed inlet in a second direction is greater than the height of the discharge port 412. The first direction and the second direction are perpendicular to each other, and the second direction is parallel to the vertical direction. The conveyor belt 21 includes a first transport section 211 and a second transport section 212 connected in sequence. One end of the first transport section 211 is located above the feed inlet, and the other end extends towards the storage bin 41 and downwards in the first direction. One end of the second transport section 212 is located outside the discharge port 412 and is connected to the first transport section 211. The other end of the second transport section 212 extends into and is fixed in the storage tank 411 through the discharge port 412. The first transport section 211 can rotate up and down around its end facing the feed inlet to drive the second transport section 212 and the storage bin 41 to move up and down.

[0036] In some embodiments, the conveying device 20 may be an integral belt conveyor mechanism. For example, such as Figure 2 and Figure 3 As shown, the conveying device 20 of this embodiment includes a driving wheel, a driven wheel, and a conveyor belt 21. The driving wheel is rotatably mounted on the machine body 10, the driven wheel is rotatably mounted on the storage tank 411, and the conveyor belt 21 passes through the discharge port 412. The two ends of the conveyor belt 21 are respectively sleeved on the driving wheel and the driven wheel.

[0037] Furthermore, the concrete feeding and spraying equipment 100 of this embodiment of the invention also includes a steering component 22. The steering component 22 is located outside the discharge port 412 and abuts against the conveyor belt 21. The steering component 22 is used to guide the transmission direction of the conveyor belt 21 to divide the conveyor belt assembly into a first transport section 211 and a second transport section 212. With this arrangement, the first transport section 211 and the second transport section 212 are seamlessly connected, which is beneficial for the compact arrangement of the conveying device 20 and facilitates the synchronous adjustment of the transport efficiency of the first transport section 211 and the second transport section 212.

[0038] The conveying device 20 also includes a drive structure for rotating the drive wheel. This drive structure may include, but is not limited to, a hydraulic motor, a reducer, and a sprocket and chain structure. The output end of the hydraulic motor is connected to the input end of the reducer. The output end of the reducer is connected to the drive wheel via the sprocket and chain structure to drive the drive wheel to rotate around a third direction, which in turn drives the driven wheel to rotate synchronously around the third direction via the conveyor belt 21. Specifically, the sprocket and chain structure includes a drive sprocket, a transmission chain, and a driven sprocket. The drive sprocket is installed at the output end of the reducer, the driven sprocket is coaxially connected to the drive wheel, and the two ends of the transmission chain are respectively sleeved on the drive sprocket and the driven sprocket. Optionally, a protective cover may also be installed on the outside of the sprocket and chain structure to improve the protection performance of the drive structure.

[0039] In some embodiments, the conveying device 20 may also be equipped with multiple flat idlers, which are spaced apart between the driving wheel and the driven wheel and arranged sequentially along the conveying path of the conveying device 20. The conveyor belt 21 is sleeved on the multiple flat idlers. This arrangement allows the flat idlers to support the conveyor belt 21, which is beneficial for the smooth conveying of concrete. Furthermore, the conveying device 20 may also be equipped with multiple deflection rollers, which are symmetrically installed in pairs on opposite sides of the conveyor belt 21 in the third direction to prevent the conveyor belt 21 from deviating during operation, thus preventing it from failing to convey concrete to the shotcrete device 30.

[0040] Specifically, such as Figure 2 , Figure 3 as well as Figure 5 As shown, the steering assembly 22 of this embodiment includes a steering wheel 221 and at least two pressure rollers 222. The central axis of the steering wheel 221 extends along a third direction and is rotatably disposed on the outside of the discharge port 412. The third direction is perpendicular to the first direction and the second direction. The conveyor belt 21 is sleeved on the steering wheel 221. The pressure rollers 222 are disposed above the conveyor belt 21 and abut against the top surface of the conveyor belt 21. At least two pressure rollers 222 are respectively disposed on opposite sides of the discharge port 412 in the third direction.

[0041] Optionally, the steering wheel 221 has a roller structure extending in a third direction. Two mounting seats are spaced apart on the outer side of the storage bin 41 in a third direction. The bearings at both ends of the steering wheel 221 are respectively mounted on the two mounting seats, so that the steering wheel 221 is rotatably mounted on the outer side of the storage bin 41 and can move synchronously with the storage bin 41. Since the first conveying section is inclined and the second conveying section is usually horizontal, the included angle between them is an obtuse angle. Therefore, by using the steering wheel 221 to redirect the transmission direction of the conveyor belt 21, it can be ensured that the conveying device 20 can transport the concrete material in the storage bin 41 to the shotcrete device 30.

[0042] Furthermore, by providing a pressure roller 222 on the top side of the conveyor belt 21, the pressure roller 222 can press the conveyor belt 21 at the connection between the first and second conveying sections, ensuring that the conveyor belt 21 at the bend can operate normally. This allows the conveyor belt 21 to smoothly transport the concrete to the shotcrete device 30 without causing a large accumulation of concrete at the bend between the first and second conveying sections. Moreover, since at least two pressure rollers 222 of the steering assembly 22 are respectively located on opposite sides of the discharge port 412 in a third-order direction, space can be left between the at least two pressure rollers 222 for the concrete to pass through, thus preventing the pressure rollers 222 from obstructing the transport of concrete. Optionally, the two pressure rollers 222 are coaxially arranged, and the two pressure rollers 222 are respectively located at both ends of the same rotating shaft. The two ends of the rotating shaft are respectively connected to bearings with seats. The two bearings with seats are fixedly arranged on the outside of the storage bin 41, so that the pressure rollers 222 are rotatably installed on the outside of the storage bin 41 and can move synchronously with the storage bin 41.

[0043] like Figure 2 , Figure 6 as well as Figure 7 As shown, the conveying device 20 of this embodiment further includes a baffle assembly 23, which includes at least two baffle plates 231. The at least two baffle plates 231 are spaced apart in a third direction. One end of each baffle plate 231 is fixedly disposed on the top side of the first conveying section 211, and the other end extends to the top side of the second conveying section 212 and extends between at least two pressure rollers 222. This arrangement can prevent concrete material on the conveyor belt 21 from tilting to both sides by the baffle plates 231, thereby reducing the risk of concrete material falling out of the conveying device 20 during the conveying process.

[0044] Optionally, the baffle plate 231 may include a baffle side plate, a pressure plate, and a rubber baffle. The pressure plate is located on the opposing sides of the two baffle side plates, and the rubber baffle is disposed between the baffle side plates and the pressure plate. The pressure plate can press and fix the rubber baffle to the inner side of the baffle side plate by bolts. The rubber baffle is made of rubber and its bottom can contact the conveyor belt, thereby reducing wear on the conveyor belt 21 caused by the baffle plate 231. Furthermore, the rubber baffle has a slotted hole for bolts to pass through. By removing or loosening the bolts, the rubber baffle between the baffle side plate and the pressure plate can be unlocked, and the height of the rubber baffle relative to the conveyor belt 21 can be adjusted by the slotted hole and the bolts. With this configuration, when the bottom of the rubber baffle wears due to long-term contact with the conveyor belt 21, resulting in a gap between its bottom and the conveyor belt 21, the height of the rubber baffle can be readjusted to ensure that the baffle plate 231 can abut against the conveyor belt 21, thus ensuring the baffle plate 231's baffle-blocking effect.

[0045] Furthermore, in some embodiments, the baffle side plate, pressure plate and rubber baffle are all bent upward at the end near the storage bin 41, so that the baffle plate 231 has a larger baffle area at the end facing the storage bin 41, thereby improving the baffle plate 231's baffle effect.

[0046] like Figures 1 to 2 as well as Figures 6 to 7 As shown, the conveying device 20 of this embodiment of the invention also includes a conveyor frame 60 and a lifting mechanism. The conveyor frame 60 is movably disposed between the shotcrete device 30 and the storage bin 41. One end of the conveying bracket facing the shotcrete device 30 is rotatably disposed on the machine body 10, and the other end is fixedly connected to the storage bin 41. The conveyor frame 60 is also provided with a mounting groove 61 through both ends, and the first transport part 211 is disposed in the mounting groove 61. The lifting mechanism is disposed on the machine body 10 and hinged to the second end. The lifting mechanism can drive the second end to drive the storage bin 41 to rotate up and down around the first end.

[0047] Specifically, in this embodiment, the machine body 10 is provided with a hinge seat, which is located on the side of the shotcrete device 30 facing the storage bin 41; the first end of the conveying bracket is provided with a hinge hole, which allows it to be rotatably connected to the hinge seat, so that the second end of the conveying bracket can rotate around the first end. The lifting mechanism can be set as a lifting cylinder, whose output end is connected to the conveyor frame 60 in a transmission manner. With this configuration, the output end of the lifting mechanism can extend upward to drive the second end of the first conveying part of the conveyor frame 60 and the conveying device 20 to rotate upward relative to the machine body 10. At this time, the second end of the conveyor frame 60 can drive the storage bin 41 connected to it to move upward, thereby lifting the storage bin 41 off the ground, so that the storage device 40 and the material gathering device 50 and the second transport part 212 inside it can all move together with the concrete feeding shotcrete equipment 100.

[0048] Of course, the output end of the lifting mechanism can be retracted downwards to drive the second end of the first conveying part of the conveyor frame 60 and the conveying device 20 to rotate downwards relative to the machine body 10. At this time, the second end of the conveyor frame 60 can drive the storage bin 41 connected to it to move downwards, so that the storage bin 41 can fall to the ground, so as to convey the mixed concrete material to the storage bin 41.

[0049] like Figure 5As shown, the storage device 40 of this embodiment of the invention further includes a material gate assembly 42, which includes a drive mechanism 421 and a cover plate 422. The drive mechanism 421 is located outside the storage silo 41 and above the discharge port 412. The cover plate 422 is located outside the storage silo 41 and is connected to the drive mechanism 421 for transmission, so as to be movably disposed above the second transport section 212. The cover plate 422 can move toward or away from the second transport section 212 under the drive of the drive mechanism 421 to cover or open the discharge port 412. The drive mechanism 421 may be, but is not limited to, a linear motor, a telescopic cylinder, etc. The shape of the cover plate 422 is adapted to the discharge port 412, or the area of ​​the cover plate 422 is larger than the area of ​​the discharge port 412, to ensure that the cover plate 422 can properly cover the discharge port 412 and can open the discharge port 412 so that the conveyor belt 21 can carry the concrete material in the storage silo 41 out of the storage silo 41.

[0050] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
