Description

Technical Field

[0001] The invention belongs to the technical field of concrete processing, and in particular relates to a feeding device for coconut shell fiber reinforced coral aggregate concrete. Background Art

[0002] With the development of social economy, more and more resources are being developed on islands. However, since the islands and reefs are located near the coast and far from the inland, transportation is inconvenient and the resources on the islands are limited, if buildings are built on the islands, a series of issues such as construction cost, source of building materials, and construction period must be considered, which brings certain difficulties to development and construction. Therefore, coconut shell fiber reinforced coral aggregate concrete, which can be prepared with local materials, is widely welcomed. However, when coconut shell fiber reinforced coral aggregate concrete is laid at a large depth, the concrete has a large downward acceleration and is prone to segregation. Summary of the invention

[0003] In view of this, the present invention discloses a coconut shell fiber reinforced coral aggregate concrete feeding device, which aims to solve the problem that when coconut shell fiber reinforced coral aggregate concrete is fed at a large depth, the concrete has a large downward acceleration and is prone to segregation.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] A feeding device for coconut shell fiber reinforced coral aggregate concrete comprises a feeding hopper and a plurality of buffer boxes, wherein the buffer boxes are hollow, and an annular connecting seat is arranged in the buffer box, and a conical groove is provided on the connecting seat, and a coaxially arranged material pipe is connected to the inner wall of the connecting seat, and the top end surface of the material pipe is flush with the conical groove; an annular supporting frame is fixed on the connecting seat, and movable plates are symmetrically hinged on both sides of the supporting frame, and adjusting plates are symmetrically hinged on the other two sides of the supporting frame, and grooves are provided on both sides of the movable plate, and mounting blocks are horizontally slidably connected in the grooves, and elastic supporting parts are provided between the mounting blocks and the grooves, and a closing plate that abuts against the adjusting plate is hinged at the end of the mounting block, and a supporting airbag is provided between the mounting block and the closing plate; a limiting structure for limiting the movable plate and the adjusting plate is provided on the connecting seat; the bottom of the material pipe is detachably connected to the adjacent buffer box, and a material pipe is also connected between the feeding hopper and the adjacent buffer box.

[0006] In this solution, a corresponding number of buffer boxes are installed according to the depth. When concrete falls into the buffer box through the material pipe, it is received by the inclined movable plate and the adjustment plate, so as to gradually slow down the gravitational potential energy of the concrete. Compared with the prior art, there is no need to lay a long horizontal pipe to slow down the acceleration of the concrete when it is transported downward, which saves space and also reduces the segregation of concrete. In addition, in this solution, according to the specifications of the concrete, the deceleration efficiency can be adjusted by changing the inclination of the adjustment plate and the movable plate; when the inclination of the adjustment plate changes, the mounting blocks at both ends of the movable plate move toward the adjustment plate under the action of the elastic support and fit with it. At this time, by inflating the support airbag, the closing plate is pushed to fit closely with the adjustment plate, so that the adjustment plate, the movable plate, and the closing plate form a relatively closed area, so that the fallen concrete can slide into the conical groove and enter the material pipe, and thus be transported to the next buffer box.

[0007] Furthermore, the side walls of the buffer box are rotatably connected to vertically arranged slide rails, and latches are arranged between the slide rails and the buffer box. The slide rails are slidably connected to slide seats, and latches are also arranged between the slide seats and the slide rails. The bottom of the material pipe is sleeved with an annular connecting plate, and the connecting plate and the adjacent slide seats are detachably connected with length-adjustable support rods; the bottom of the connecting seat is ball-jointed to a plurality of fixing rods, and the fixing rods are coaxially slidably connected to adjusting rods, the ends of the adjusting rods are ball-jointed to the adjacent side walls of the buffer box, and the fixing rods are provided with locking pins for limiting the sliding of the adjusting rods.

[0008] In this solution, the position of the material pipe at the bottom in the buffer box can be changed by rotating the slide rail, sliding the slide seat and adjusting the length of the support rod, thereby avoiding continuous accumulation of concrete at the same position of the adjustment plate and the movable plate, preventing concrete blockage. In addition, by removing the locking pin, the adjustment rod can slide relative to the fixed rod, thereby adjusting the position of the connecting seat, thereby adjusting the horizontal position of the material pipe, which can save the need to lay horizontal pipes.

[0009] Furthermore, the limiting structure includes four sliding grooves opened on the connecting seat, the sliding grooves are all facing the axis of the connecting seat, the supporting seats are slidably connected in the sliding grooves, the supporting seats are provided with limiting pins for limiting their sliding, the movable plate and the adjusting plate are hinged with support rods, and the support rods are hinged to the corresponding support seats.

[0010] In this solution, by sliding the support seat, the support seat can drive the adjustment plate and the movable plate to deflect through the support rod, so as to change the angle of the adjustment plate and the movable plate.

[0011] Furthermore, a filling airbag is provided at the bottom of the mounting block, and the filling airbag is communicated with an adjacent supporting airbag.

[0012] Furthermore, a vibration generating device is provided below the connecting seat.

[0013] Furthermore, an anti-corrosion protective layer is provided at the hinges between the movable plate, the adjustment plate and the connecting seat.

[0014] Furthermore, rubber layers are provided at the edges of the adjusting plate, the movable plate, the mounting block and the closing plate.

[0015] Other advantages, objectives and features of the present invention will be described in the following description and will be apparent to those skilled in the art to some extent, or those skilled in the art may be taught from the practice of the present invention. The objectives and other advantages of the present invention may be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] like Figures 1 to 3 As shown:

[0022] A coconut shell fiber reinforced coral aggregate concrete feeding device, comprising a feed hopper 1 and a plurality of buffer boxes 2, wherein the buffer boxes 2 are hollow, and an annular connecting seat is arranged in the buffer box 2, and a conical groove is provided on the connecting seat, and a coaxially arranged material pipe 3 is connected to the inner wall of the connecting seat, and the top end surface of the material pipe 3 is flush with the conical groove; an annular support frame 4 is fixed on the connecting seat, and movable plates 5 are symmetrically hinged on both sides of the supporting frame 4, and adjustment plates 6 are symmetrically hinged on the other two sides of the supporting frame 4, and grooves are provided on both sides of the movable plate 5, and mounting blocks 7 are horizontally slidably connected in the grooves, and elastic support members 8 are provided between the mounting blocks 7 and the grooves, and a closing plate 9 that abuts against the adjustment plate 6 is hinged at the end of the mounting block 7, and a supporting airbag 10 is provided between the mounting block 7 and the closing plate 9; a limiting structure for limiting the movable plate 5 and the adjustment plate 6 is provided on the connecting seat; the bottom of the material pipe 3 is detachably connected to the adjacent buffer box 2, and a material pipe 3 is also connected between the feed hopper 1 and the adjacent buffer box 2.

[0023] In this scheme, a corresponding number of buffer boxes 2 are installed according to the depth, and the buffer boxes 2 are fixed to the outside. When concrete falls into the buffer box 2 through the material pipe 3, it is received by the inclined movable plate 5 and the adjustment plate 6, so as to gradually slow down the gravitational potential energy of the concrete. Compared with the prior art, there is no need to lay a long horizontal pipeline to slow down the acceleration of the concrete when it is transported downward, which saves space and also reduces the segregation of concrete. In addition, in this scheme, according to the specifications of the concrete, the deceleration efficiency can be adjusted by changing the inclination of the adjustment plate 6 and the movable plate 5; when the inclination of the adjustment plate 6 changes, the mounting blocks 7 at both ends of the movable plate 5 move toward the adjustment plate 6 under the action of the elastic support member 8 and fit with it. At this time, by inflating the support airbag 10, the closing plate 9 is pushed to fit closely with the adjustment plate 6, so that the adjustment plate 6, the movable plate 5, and the closing plate 9 form a relatively closed area, so that the fallen concrete can slide into the conical groove and enter the material pipe 3, so as to be transported to the next buffer box 2. In order to enhance stability, a latch may be provided between the mounting block 7 and the movable plate 5 to prevent the mounting block 7 from shaking.

[0024] In this embodiment, the side walls of the buffer box 2 are rotatably connected with vertically arranged slide rails 11, and latches are arranged between the slide rails 11 and the buffer box 2 (conventional technical means, so not drawn in the figure), the slide rails 11 are slidably connected with slide seats 12, and latches are also arranged between the slide seats 12 and the slide rails 11, and the bottom of the material pipe 3 is sleeved with an annular connecting plate 13, and the connecting plate 13 and the adjacent slide seats 12 are detachably connected with length-adjustable support rods 14; the bottom of the connecting seat is ball-jointedly connected with a plurality of fixing rods 15, and the fixing rods 15 are coaxially slidably connected with adjusting rods 16, and the ends of the adjusting rods 16 are ball-jointedly connected with the adjacent side walls of the buffer box 2, and the fixing rods 15 are provided with locking pins for limiting the sliding of the adjusting rods 16 (conventional technical means, so not drawn in the figure).

[0025] In this solution, by rotating the slide rail 11, sliding the slide seat 12 and adjusting the length of the support rod 14, the position of the material pipe 3 at the bottom in the buffer box 2 can be changed, thereby avoiding continuous accumulation of concrete at the same position of the adjustment plate 6 and the movable plate 5, and preventing concrete blockage. In addition, by removing the locking pin, the adjustment rod 16 can slide relative to the fixed rod 15, thereby adjusting the position of the connecting seat, thereby adjusting the horizontal position of the material pipe 3, which can save the need to lay horizontal pipelines.

[0026] In this embodiment, the limiting structure includes four sliding grooves opened on the connecting seat, and the sliding grooves are all facing the axis of the connecting seat. The support seats 17 are slidably connected in the sliding grooves, and the support seats 17 are provided with limiting pins for limiting their sliding. The movable plate 5 and the adjustment plate 6 are both hinged with support rods 18, and the support rods 18 are hinged to the corresponding support seats 17.

[0027] In this solution, by sliding the support seat 17, the support seat 17 can drive the adjustment plate 6 and the movable plate 5 to deflect through the support rod 18, so as to change the angle of the adjustment plate 6 and the movable plate 5.

[0028] In this embodiment, a filling airbag is provided at the bottom of the mounting block 7 , and the filling airbag is communicated with the adjacent supporting airbag 10 .

[0029] By providing a filling air bag, the vacant space at the bottom of the mounting block 7 is filled to prevent concrete from overflowing.

[0030] In this embodiment, a vibration generating device is provided below the connecting seat, so as to make the connecting seat vibrate, thereby preventing the accumulation of concrete from clogging the conical groove and the material pipe 3.

[0031] In this embodiment, an anti-corrosion protective layer is provided at the hinges between the movable plate 5, the adjustment plate 6 and the connecting seat.

[0032] In this embodiment, a rubber layer is provided at the edges of the adjusting plate 6, the movable plate 5, the mounting block 7 and the closing plate 9, so that the fitting parts of the adjusting plate 6, the movable plate 5, the mounting block 7 and the closing plate 9 are more tightly connected to prevent concrete from overflowing.

[0033] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
