Description

Technical Field

[0001] This utility model relates to the field of shotcrete machinery and equipment technology, specifically to a hopper-feed shotcrete device. Background Technology

[0002] Existing Chinese patent document with application number 201821997380.0 discloses an automatic feeding shotcrete device, including a frame; a walking assembly disposed at the bottom of the frame; a shotcrete machine disposed on the frame, and a shotcrete pipe connected to the shotcrete machine disposed on the frame; and a tilting power assembly disposed between the hopper and the frame, the tilting power assembly driving the hopper to switch between the feeding and unloading positions. This automatic feeding shotcrete device has the following shortcomings:

[0003] 1) When the hopper is tilted to the unloading station to unload, blockages are likely to occur, resulting in incomplete unloading;

[0004] 2) The hopper is only equipped with one discharge port, and each time it is turned over, it only discharges material to one shotcrete machine, resulting in poor construction efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a hopper-loading shotcrete device that helps to prevent blockage and incomplete unloading.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A hopper-loaded shotcrete device includes a frame, a hopper, and a shotcrete machine. The shotcrete machine is mounted on the frame, and the hopper is tilted and mounted on the frame for dumping material into the inlet at the top of the shotcrete machine after loading. The frame is equipped with a tilting power mechanism for driving the hopper to switch between a loading position and a unloading position. The hopper-loaded shotcrete device also includes an elastic support seat for supporting the hopper when it is in the unloading position. The hopper is equipped with a vibrator, and the frame is equipped with a positioning part for positioning the bottom of the elastic support seat.

[0008] As a further improvement to the above technical solution:

[0009] The elastic support includes a barrel sleeve, an elastic element, and a support rod. The bottom end of the support rod is movably inserted into the barrel sleeve, and the top end is provided with a top support part for supporting the hopper. The elastic element is located inside the barrel sleeve and abuts against the barrel sleeve and the support rod. The positioning part is a positioning groove adapted to the bottom of the barrel sleeve.

[0010] The top support can be a flat surface, an arc surface, or a spherical surface.

[0011] The elastic element is a spring.

[0012] The frame has a support frame on one side of the shotcrete machine. The top of the support frame is higher than the feed inlet at the top of the shotcrete machine. One end of the hopper is hinged to the top of the support frame, and the other end has a support part for the elastic support seat to support it. The middle part has a hinge part. The turning power mechanism is a telescopic power mechanism with one end hinged to the frame and the other end hinged to the hinge part.

[0013] The telescopic power mechanism includes a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0014] The shotcrete machine and positioning part are located at both ends of the frame, and the tilting power mechanism is hinged to the middle of the frame.

[0015] The shotcrete machine is provided in at least two. The hopper has at least two discharge ports at one end above the support frame and a feed port at the top of the other end. Each discharge port is arranged in correspondence with the feed port at the top of each shotcrete machine. Each discharge port is provided with an openable and closable discharge gate.

[0016] The hopper has a feeding chamber and at least two distributing channels. The feeding port is located at the top of the feeding chamber, and each of the discharge ports is connected to one side of the feeding chamber through a distributing channel.

[0017] The frame is equipped with locking pins for locking the hopper when it is in the loading position.

[0018] Compared with the prior art, the advantages of this utility model are:

[0019] This novel hopper-loaded shotcrete device operates by having a concrete mixer truck / dump truck transport the shotcrete from the concrete mixing plant to the site, where it is directly unloaded into the hopper located at the loading station. Once the hopper is fully loaded, a tilting mechanism drives the hopper to tilt from the loading station to the unloading station. An elastic support seat is then positioned at the positioning point, supporting the hopper. Next, a vibrator is activated to vibrate the hopper, discharging the material into the feed inlet at the top of the shotcrete machine. The vibrator helps prevent blockages and incomplete unloading. During vibration unloading at the unloading station, the elastic support seat relieves the tilting mechanism of its power, reducing vibration-induced vibration effects. Furthermore, the elasticity of the support seat enhances the vibration effect of the hopper. Attached Figure Description

[0030] Figures 1 to 4This invention illustrates an embodiment of a hopper-feed shotcrete device. The hopper-feed shotcrete device of this embodiment includes a frame 1, a hopper 2, and a shotcrete machine 3. The shotcrete machine 3 is mounted on the frame 1. The hopper 2 is tilted and mounted on the frame 1 to pour material into the inlet at the top of the shotcrete machine 3 after feeding. The frame 1 is equipped with a tilting power mechanism 4 to drive the hopper 2 to switch between the feeding and unloading positions. The hopper-feed shotcrete device also includes an elastic support seat 5 for supporting the hopper 2 when it is in the unloading position. The hopper 2 is equipped with a vibrator 6, and the frame 1 is equipped with a positioning part 7 for positioning the bottom of the elastic support seat 5.

[0031] In operation, a concrete mixer truck / dump truck transports the shotcrete from the concrete mixing plant to the site and unloads it directly into the hopper 2 located at the loading station. Once the hopper 2 is filled to the required level, the tilting power mechanism 4 drives the hopper 2 to tilt from the loading station to the unloading station. The elastic support seat 5 is then positioned on the positioning part 7 and supports the hopper 2. Next, the vibrator 6 is activated to vibrate the hopper 2, discharging the material from the hopper 2 into the feed inlet at the top of the shotcrete machine 3. The vibrator 6, which causes the hopper 2 to vibrate and unload, helps prevent blockages and incomplete unloading. During the vibration unloading at the unloading station, the hopper 2 is supported by the elastic support seat 5. This not only relieves the power of the tilting power mechanism 4, reducing its impact from vibration, but also, due to its elasticity, helps improve the vibration effect of the hopper 2.

[0032] Furthermore, such as Figure 2 As shown, in this embodiment, the elastic support base 5 includes a barrel sleeve 51, an elastic element 52, and a support rod 53. The bottom end of the support rod 53 is movably inserted into the barrel sleeve 51, and the top end is provided with a top support portion 531 for supporting the hopper 2. The elastic element 52 is disposed inside the barrel sleeve 51 and abuts against the barrel sleeve 51 and the support rod 53. The positioning portion 7 is a positioning groove adapted to the bottom of the barrel sleeve 51. When the hopper 2 vibrates and unloads at the unloading station, the bottom of the elastic support base 5 is positioned in the positioning groove, and the top support portion 531 supports the hopper 2. After the hopper 2 has finished unloading, under the action of the tilting power mechanism 4 assisting in tilting the hopper 2, the barrel sleeve 51 is removed from the positioning groove, thereby removing the elastic support base 5. In this way, under the downward driving action of the tilting power mechanism 4, the hopper 2 can be tilted down to the loading station.

[0033] Furthermore, in this embodiment, the top support 531 is a top support plane, which can increase the top support area by supporting the hopper 2. Of course, in other embodiments, the top support 531 can also be an arc surface or a spherical surface.

[0034] Furthermore, in this embodiment, the elastic element 52 is a spring. Of course, in other embodiments, the elastic element 52 may also be a rubber pad, etc.

[0035] Furthermore, in this embodiment, the frame 1 is provided with a support frame 11 on one side of the shotcrete machine 3. The top of the support frame 11 is higher than the feed inlet at the top of the shotcrete machine 3. One end of the hopper 2 is hinged to the top of the support frame 11, and the other end has a support portion 21 for the elastic support seat 5 to support it. A hinge portion 22 is provided in the middle. The tilting power mechanism 4 is a telescopic power mechanism that is hinged at one end to the frame 1 and at the other end to the hinge portion 22. The overall structure is reasonably arranged to meet the requirements of feeding the hopper 2 at the feeding station and unloading it at the unloading station. Preferably, the shotcrete machine 3 and the positioning part 7 are distributed at both ends of the frame 1, and the tilting power mechanism 4 is hinged to the middle of the frame 1.

[0036] Furthermore, in this embodiment, the telescopic power mechanism includes a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0037] Furthermore, such as Figure 3 As shown, in this embodiment, the shotcrete machine 3 has at least two (two are used as an example in this embodiment). The hopper 2 has at least two discharge ports 23 at one end above the support frame 11, and a feed port 24 at the top of the other end. Each discharge port 23 is arranged in a one-to-one correspondence with the feed port at the top of each shotcrete machine 3. Each discharge port 23 is equipped with an openable and closable discharge gate 8. Since the hopper 2 has at least two discharge ports 23, when the hopper 2 is in the unloading position in the upward tilted state, each discharge port 23 corresponds to the feed port at the top of each shotcrete machine 3, realizing the unloading of multiple shotcrete machines 3, which improves construction efficiency.

[0038] Furthermore, such as Figure 4 As shown, in this embodiment, the hopper 2 has a feeding chamber 25 and at least two distributing channels 26. The feeding port 24 is located at the top of the feeding chamber 25, and each discharge port 23 is connected to one side of the feeding chamber 25 through a distributing channel 26. Preferably, when the hopper 2 is in the loading position, the end of the distributing channel 26 near the feeding chamber 25 is lower than the other end, which facilitates material storage in the feeding chamber 25. When the hopper 2 is in the unloading position, the end of the distributing channel 26 near the feeding chamber 25 is higher than the other end, which facilitates material unloading.

[0039] Furthermore, in this embodiment, the frame 1 is provided with a locking pin 9 for locking the hopper 2 when it is in the feeding position. Locking the hopper 2 with the locking pin 9 when it is in the feeding position helps to stabilize the feeding process. Specifically, the hopper 2 is provided with a locking hole 27. When the hopper 2 is in the feeding position, the locking hole 27 corresponds to the locking pin 9, and the locking pin 9 can be inserted into the locking hole 27 to lock the hopper 2.

[0040] Specifically, the vibrator 6 is a conventional component that can be purchased from the market and installed on the hopper 2 with bolts.

[0041] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
