Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for concrete mixer trucks, specifically to a concrete chute truck. Background Technology

[0002] Currently, during the pouring of municipal cement concrete pavements, due to the complex on-site construction environment, some poured pavements do not form heavy-duty roads for concrete mixer trucks to pass through. In this case, in order to meet the demand for concrete pouring, the conventional practice is to manually transport concrete using hand-operated or electric wheelbarrows. This method has a small wheelbarrow capacity, requires multiple loadings, and is inefficient; it is difficult to meet the demand for municipal cement concrete pavement pouring.

[0003] Chinese utility model patent with publication number CN215593590U discloses a concrete chute device for curbstone and edge stone backrest construction. The above technical solution uses the cooperation of bottom frame, top frame, vertical pipe, vertical rod, lock hole, locking mechanism, hopper, discharge pipe and guide ring to adjust the height and flow of discharge pipe. Combined with the use of wheels and pusher, it realizes convenient concrete pouring and reduces overflow.

[0004] However, the aforementioned chute trucks are not convenient for construction on specific municipal roads, resulting in situations where there are no roads available for concrete mixer trucks to pass through, or where there are roads but the mixer trucks cannot enter, or where the road surface cannot withstand the heavy pressure of the mixer trucks, lacking a complex construction environment, and not suitable for long-distance transport of concrete on heavy-duty roads where concrete mixer trucks have not yet been established.

The second chute assembly is installed in the first subframe body and is adapted to receive the concrete flowing down from the first chute. The third chute assembly is installed in the second subframe body, and the third chute assembly is adapted to receive the concrete flowing down from the second chute assembly. The first chute assembly, the second chute assembly, and the third chute assembly are arranged at an angle downwards and connected end to end in sequence.

[0007] Optionally, the first mounting frame includes a connecting frame horizontally connected to the middle of one side of the main frame and a hinge connected to the connecting frame near the receiving bin, and the bottom of the connecting frame is fixedly connected by a diagonal brace. The hinge includes two first sleeves symmetrically connected to the side of the connecting frame, a rotating shaft sleeved on the two first sleeves, and two second sleeves symmetrically connected to the top edge of the first chute. The two ends of the rotating shaft extend out of the corresponding first sleeve and are respectively sleeved on the corresponding second sleeve.

[0008] Optionally, the first angle adjustment structure includes a first hook connected to the outer wall of the receiving hopper, a first connecting chain, and a first bracket spanning across the first chute. The top end of the first connecting chain is hooked onto the first hook, and the bottom end of the first connecting chain is connected to the first bracket.

[0009] Optionally, the bottom side of the first chute is provided with two symmetrically arranged slides, which are inclined downwards and close together along the interior of the first chute.

[0010] Optionally, the receiving bin includes a square bin body and a prismatic bin body that are coaxially and integrally connected. The square bin body is inserted into the main frame body, and the prismatic bin body is located directly below the square bin body.

[0011] Optionally, the manual opening and closing valve includes a valve body installed on the bottom opening of the prismatic chamber and a valve installed on the valve body. The upper and lower ends of the valve body are respectively provided with an upper opening and a lower opening. The upper opening is connected to the bottom opening of the prismatic chamber, and the valve is installed on the lower opening.

[0012] Optionally, the valve includes two triangular hinge plates rotatably connected to both sides of the valve body, an arc-shaped door connected to the bottom end of the two triangular hinge plates, and a handle horizontally connected to the outside of the two triangular hinge plates, wherein the arc-shaped door is adapted to block the lower opening of the valve body.

[0013] Optionally, the triangular hinge plate is configured as a fan-shaped structure, and the top end of the triangular hinge plate is rotatably connected to the outer wall of the valve body by a pin and a fastening nut, and the bottom side of the triangular hinge plate is an arc-shaped structure.

[0014] Optionally, the main frame includes a base frame, four vertical frames connected around the base frame, and four wheels connected to the bottom of the base frame.

[0015] Optionally, a support beam is also horizontally connected to the side of the main frame away from the connecting frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In the technical solution of this utility model, the concrete chute truck includes a main frame, a first sub-frame, a second sub-frame, a receiving bin, a manual opening and closing valve, a first chute assembly, a second chute assembly, and a third chute assembly. When a concrete transport truck delivers concrete to the receiving bin of the concrete chute truck, the receiving bin is connected to the top of the main frame and serves to receive and temporarily store the concrete. When it is necessary to deliver the concrete to a designated location, the manual opening and closing valve is operated. The manual opening and closing valve is installed at the bottom of the receiving bin. By manually opening the valve, the concrete in the receiving bin flows downward under the action of gravity. The top of the first chute in the first chute assembly is rotatably connected to a first mounting frame, which is installed on one side of the main frame. The first chute is inclined downward and extends to the other side of the receiving bin and the manual opening and closing valve, so that the concrete flowing out of the receiving bin can smoothly enter the first chute. A first angle adjustment structure is installed between the receiving bin and the first chute, with its top end connected to the side wall of the receiving bin and its other end connected across the lower side of the first chute. By adjusting the first angle adjustment structure, the tilt angle of the first chute can be changed to adapt to different construction needs and control the flow speed and direction of concrete. When long-distance concrete transportation is required, considering the complex on-site construction environment during the pouring of municipal cement concrete pavement, some poured pavement does not form a heavy-duty road for concrete mixer trucks. Since the first chute assembly, second chute assembly, and third chute assembly are tilted downwards and connected end to end, the second chute assembly and the third chute assembly can be used. The second chute assembly receives the concrete flowing down from the first chute, and the third chute assembly receives the concrete flowing down from the second chute. In this way, long-distance concrete transportation can be completed through segmented combination.

[0017] 2. This concrete chute truck features an independent main frame, facilitating flexible movement on the construction site. It can transport concrete from the receiving point to different construction locations, reducing transfer steps and improving construction efficiency. The manually operated valve allows for manual control of concrete discharge according to the construction progress, making operation simple and easy to master. Construction personnel can open or close the valve at any time as needed, precisely controlling the concrete output. The design of the first chute assembly increases the adaptability of the device. The rotating connection between the first chute and the first mounting frame, along with the first angle adjustment structure, makes the angle of the first chute adjustable. In different construction scenarios, such as conveying concrete to higher locations or long-distance horizontal transport, the angle of the first chute can be adjusted to meet requirements, expanding the applicability of this concrete chute truck.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0023] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0024] Please see Figure 1-7As shown, this utility model embodiment provides a concrete chute truck, which includes a main frame 1, a receiving bin 2, a manual opening and closing valve 3, a first chute assembly 4, a first auxiliary frame 8, a second auxiliary frame 8, a second chute assembly 5, and a third chute assembly 6, wherein: The concrete chute truck has an independent main frame 1, which facilitates flexible movement on the construction site and can transport concrete from the receiving point to different construction locations, reducing transfer links in the concrete transportation process and improving construction efficiency. The receiving bin 2 is connected to the top of the main frame 1 and is used to receive and store concrete transported by the tanker truck. The manual opening and closing valve 3 is installed at the bottom of the receiving bin 2 and is used to open and close the receiving bin 2. The first chute assembly 4 includes a first mounting frame 41, a first chute 42, and a first angle adjustment mechanism. The entire structure 43 has a first mounting bracket 41 installed on one side of the main frame 1, the top of the first chute 42 rotatably connected to the first mounting bracket 41, a first angle adjustment structure 43 installed between the receiving bin 2 and the first chute 42, the first mounting bracket 41 and the top of the first chute 42 are hinged together, the first chute 42 is inclined downward and extends to the other side of the receiving bin 2 and the manual opening and closing valve 3, the top of the first angle adjustment structure 43 is connected to the side wall of the receiving bin 2, and the other end is connected across the lower side of the first chute 42.

[0025] Since the first chute assembly 4, the second chute assembly 5, and the third chute assembly 6 are inclined downwards and connected end to end, and the second chute assembly 5 is installed inside the first sub-frame 7, the second chute assembly 5 is suitable for receiving the concrete flowing down from the first chute 42; the third chute assembly 6 is installed inside the second sub-frame 8, and the third chute assembly 6 is suitable for receiving the concrete flowing down from the second chute assembly 5, long-distance concrete transportation can be completed through segmented assembly.

[0026] Specifically, in this embodiment, the concrete transport truck delivers concrete to the receiving hopper 2 of the concrete chute truck. The receiving hopper 2 is connected to the top of the main frame 1 and serves to receive and temporarily store concrete. When concrete needs to be delivered to a designated location, the manual opening and closing valve 3 is operated. The manual opening and closing valve 3 is installed at the bottom of the receiving hopper 2. By manually opening the valve, the concrete in the receiving hopper 2 flows downward under the action of gravity. The top of the first chute 42 in the first chute assembly 4 is rotatably connected to the first mounting frame 41, which is installed on one side of the main frame 1. The first chute 42 is inclined downward and extends to the other side of the receiving hopper 2 and the manual opening and closing valve 3, so that the concrete flowing out of the receiving hopper 2 can smoothly enter the first chute 42. The first angle adjustment structure 43 is installed between the receiving hopper 2 and the first chute 42, with its top end connected to the side wall of the receiving hopper 2 and its other end connected across the lower side of the first chute 42. By adjusting the first angle adjustment structure 43, the inclination angle of the first chute 42 can be changed, thereby adapting to different construction needs and controlling the flow speed and direction of concrete.

[0027] The concrete first chute truck has an independent main frame 1, which facilitates flexible movement on the construction site and can transport concrete from the receiving point to different construction locations, reducing transfer links in the concrete transportation process and improving construction efficiency. The manual opening and closing valve 3 allows for manual control of concrete discharge according to the construction progress, making operation simple and easy to master. Construction personnel can open or close the valve at any time according to actual needs, precisely controlling the concrete output. The design of the first chute assembly 4 increases the adaptability of the device. The rotatable connection between the first chute 42 and the first mounting frame 41, as well as the first angle adjustment structure 43, make the angle of the first chute 42 adjustable. In different construction scenarios, such as conveying concrete to higher locations or long-distance horizontal transport, the requirements can be met by adjusting the angle of the first chute, expanding the applicability of this concrete first chute truck.

[0028] The downward-sloping design of the first chute 42 ensures that concrete flows smoothly from the receiving hopper 2 to the construction point, reducing blockages and residues during transport and improving reliability. The second chute assembly 5 is installed inside the first sub-frame 7, with one side of the second chute assembly 5 positioned at the bottom of the first chute 42 to receive the concrete flowing in. The third chute assembly 6 is installed inside the second sub-frame 8, with one side of the third chute assembly 6 positioned at the bottom of the second chute assembly 5 to receive the concrete flowing in, thus enabling segmented long-distance transport.

[0029] Understandably, depending on the construction length of the municipal road, multiple sub-frames can be sequentially connected to the main frame 1 of the concrete chute truck. Each sub-frame is equipped with a chute assembly, thus enabling long-distance concrete transportation by receiving the concrete from the previous section layer by layer.

[0030] Preferably, by reasonably adjusting the angle of the first chute 42, the flow rate of the concrete can be controlled, preventing segregation caused by excessively fast flow, thus ensuring the quality of the concrete and improving construction quality. The use of this device reduces the manual handling of concrete, lowering the labor intensity and safety risks for construction workers. It also avoids problems such as concrete spillage that may occur during manual handling, helping to maintain a clean and safe construction site.

[0031] Please see Figure 6 As shown, in a preferred embodiment of the present invention, the first mounting frame 41 includes a connecting frame 411 and a hinge 412. The connecting frame 411 is horizontally connected to the middle of one side of the main frame 1, and the hinge 412 is connected to the side of the connecting frame 411 near the receiving bin 2. The bottom of the connecting frame 411 is fixedly connected by a diagonal brace 4111. The hinge 412 includes two first sleeves 4121, a rotating shaft 4122, and two second sleeves 4123. The two first sleeves 4121 are symmetrically connected to the sides of the connecting frame 411. The rotating shaft 4122 is sleeved on the two first sleeves 4121. The two second sleeves 4123 are symmetrically connected to the top edge of the first chute 42. The two ends of the rotating shaft 4122 extend out of the corresponding first sleeve 4121 and are respectively sleeved on the corresponding second sleeve 4123.

[0032] Specifically, in the technical solution of this embodiment, the connecting frame 411 is horizontally connected to the middle of one side of the main vehicle frame 1, and its bottom is fixedly connected by the diagonal brace 4111 to enhance the stability of the connecting frame 411 and ensure that the first mounting bracket 41 can be firmly installed on the main vehicle frame 1. The hinge 412 is located on the side of the connecting frame 411 near the receiving bin 2, wherein two first sleeves 4121 are symmetrically connected to the side of the connecting frame 411, and the rotating shaft 4122 is sleeved on the two first sleeves 4121 to form a rotatable connecting structure; two second sleeves 4123 are symmetrically connected to the top edge of the first chute 42, and the two ends of the rotating shaft 4122 extend out of the corresponding first sleeves 4121 and are respectively sleeved on the corresponding second sleeves 4123, thereby connecting the top of the first chute 42 and the first mounting bracket 41 in a hinged manner through the hinge 412. In this way, the first chute 42 can be adjusted in angle around the rotation axis 4122 within a certain range. Under the action of the first angle adjustment structure 43, it can be stably fixed at different tilt angles to meet the requirements of the first chute angle under different construction scenarios.

[0033] Therefore, the structural design of the hinge 412 ensures that the connection between the first chute 42 and the first mounting frame 41 is firm and reliable, and can remain stable during frequent angle adjustments and concrete conveying, without affecting construction efficiency and quality due to loose connection.

[0034] Please see Figure 6 As shown, in a preferred embodiment of the present invention, the first angle adjustment structure 43 includes a first hook 431, a first connecting chain 432 and a first bracket 433. The first hook 431 is connected to the outer wall of the receiving bin 2, the first bracket 433 is connected across the first chute 42, the top end of the first connecting chain 432 is hooked on the first hook 431, and the bottom end of the first connecting chain 432 is connected to the first bracket 433.

[0035] Specifically, in this embodiment, the first hook 431 is firmly connected to the outer wall of the receiving hopper 2, serving as a fixed fulcrum for the entire first angle adjustment structure 43 and providing a stable reference for subsequent connections. The first bracket 433 spans and connects to the first chute 42. In this way, the first bracket 433 can adjust its position and posture accordingly as the angle of the first chute 42 changes, ensuring close following and coordinated action with the first chute 42. The top end of the first connecting chain 432 is hooked onto the first hook 431, and the bottom end is connected to the first bracket 433. The first connecting chain 432 adopts a flexible connection method, allowing the first chute 42 to adjust its angle around the rotation axis 4122 within a certain range, while adapting to different angle requirements by changing the length of the first connecting chain 432.

[0036] When it is necessary to adjust the inclination angle of the first chute 42, the operator can do so by increasing or decreasing the length of the first connecting chain 432. For example, when it is necessary to increase the inclination angle of the first chute 42, the first connecting chain 432 can be loosened appropriately, so that the first chute 42 rotates downward around the rotation axis 4122 under its own weight or external force (such as the impact force of concrete flow) until the desired angle is reached; conversely, if it is necessary to decrease the inclination angle, the first connecting chain 432 is tightened, pulling the first chute 42 to rotate upward.

[0037] The design of the first angle adjustment structure 43 is simple and intuitive to operate. Operators only need to adjust the length of the first connecting chain 432 to change the angle of the first chute 42, without the need for complicated tools or mechanical devices. This reduces the difficulty of operation and the professional skills required of operators, improves construction efficiency, and enables construction personnel to quickly respond to on-site needs and adjust the angle of the first chute in a timely manner to adapt to different construction conditions.

[0038] Please see Figure 6 As shown, in a preferred embodiment of the present invention, two symmetrically arranged slide plates 421 are provided inside the bottom side of the first chute 42, and the two slide plates 421 are inclined downward and close to each other along the inside of the first chute 42.

[0039] After the concrete is discharged from the receiving hopper 2 through the manually operated valve 3, it enters the first chute 42. Inside the first chute 42, the concrete falls onto two symmetrical, downwardly inclined, and closely spaced chute plates 421. Due to the inclination and proximity of the chute plates 421, the concrete, under its own weight, flows downward along the surface of the chute plates 421 and toward the center, eventually being discharged from the outlet of the first chute 42 and flowing to the designated construction location.

[0040] Thus, the symmetrical arrangement of the chute 421 provides a relatively concentrated and stable flow channel for the concrete. This structure guides the concrete to be evenly distributed at the bottom of the first chute 42 and keeps it in a relatively stable state during flow, reducing segregation that may occur due to flow dispersion, ensuring the quality of the concrete during transportation, and improving the stability of construction quality.

[0041] Please see Figure 4 As shown, in another preferred embodiment of the present invention, the receiving bin 2 includes a square bin body 21 and a prismatic bin body 22 that are coaxially and integrally connected. The square bin body 21 is inserted into the main frame body 1, and the prismatic bin body 22 is located directly below the square bin body 21.

[0042] When a concrete truck delivers concrete to receiving silo 2, the concrete first enters the square silo 21. Since the square silo 21 and the rhomboid silo 22 are coaxially connected, the concrete briefly accumulates within the square silo 21 before smoothly flowing into the rhomboid silo 22 below. The shape of the rhomboid silo 22 allows the concrete to evenly accumulate towards the center within it and flow downwards under gravity, eventually reaching the bottom of receiving silo 2, preparing it for subsequent discharge via the manually operated valve 3.

[0043] Please see Figure 5 As shown, in another preferred embodiment of this utility model, the manual opening and closing valve 3 includes a valve body 31 and a valve 32. The valve body 31 is installed on the bottom opening of the prismatic chamber 22, and the valve 32 is installed on the valve body 31. The upper and lower ends of the valve body 31 are respectively provided with an upper opening 311 and a lower opening 312. The upper opening 311 is connected to the bottom opening of the prismatic chamber 22, and the valve 32 is installed on the lower opening 312.

[0044] When concrete needs to be discharged, the operator manually opens valve 32. At this time, the lower opening 312 of valve body 31 opens, and the concrete, under the action of gravity, passes through the bottom opening of the prismatic silo 22, the upper opening 311 and the lower opening 312 of valve body 31 in sequence, and is finally discharged into the first chute 42. When concrete discharge is paused, the operator manually closes valve 32, so that the lower opening 312 of valve body 31 is closed, and the concrete stops being discharged from receiving silo 2 and remains inside receiving silo 2.

[0045] The design of the manually operated valve 3 ensures that the discharge of concrete is completely controlled by the operator. The valve 32 is installed on the lower opening 312 of the valve body 31, and the flow of concrete can be started and stopped with a simple opening and closing action. This direct and precise control method ensures that concrete is accurately discharged when needed, avoiding unnecessary waste. At the same time, it can also flexibly adjust the supply of concrete according to the construction progress and demand, improving the flexibility and efficiency of construction.

[0046] Please see Figure 5 As shown, in another preferred embodiment of the present invention, the valve 32 includes an arc-shaped door 321, two triangular hinge plates 322 and a handle 323. The two triangular hinge plates 322 are rotatably connected to both sides of the valve body 31. The arc-shaped door 321 is connected to the bottom end of the two triangular hinge plates 322. The handle 323 is horizontally connected to the outside of the two triangular hinge plates 322. The arc-shaped door 321 is adapted to block the lower opening 312 of the valve body 31.

[0047] When it is necessary to close valve 32, force is applied by handle 323, causing the two triangular hinge plates 322 to rotate inward toward the valve body 31, while driving the arc-shaped door 321 to move to the lower opening 312 of valve body 31 and fit tightly against the lower opening 312, thereby blocking the discharge channel of concrete.

[0048] When valve 32 needs to be opened, the handle 323 is operated in the opposite direction, causing the triangular hinge plate 322 to rotate outward of the valve body 31, which drives the arc-shaped door 321 away from the lower opening 312, opening the discharge channel of concrete, so that the concrete can be discharged smoothly under the action of gravity.

[0049] Please see Figure 5 As shown, in another preferred embodiment of the present invention, the triangular hinge plate 322 is configured as a fan-shaped structure, and the top end of the triangular hinge plate 322 is rotatably connected to the outer wall of the valve body 31 through the pin 3221 and the fastening nut 3222. The bottom side of the triangular hinge plate 322 is an arc-shaped structure.

[0050] Thus, the top of the triangular hinge plate 322 is rotatably connected to the outer wall of the valve body 31 via a pin 3221 and a fastening nut 3222. This connection method ensures the rotational stability of the triangular hinge plate 322. When the valve 32 is closed, the arc-shaped door 321 can tightly fit against the lower opening 312 of the valve body 31, thereby effectively preventing concrete leakage and improving the valve's sealing performance. The bottom side of the triangular hinge plate 322 has an arc-shaped structure, which matches the shape of the arc-shaped door 321, allowing the arc-shaped door 321 to fit against the lower opening 312 more smoothly when closed, further enhancing the sealing effect.

[0051] Please see Figure 7 As shown, in another preferred embodiment of the present invention, the main frame 1 includes a base frame 11, four vertical frames 12 vertically connected around the base frame 11, and four wheels 13 connected to the bottom of the base frame 11.

[0052] At the construction site, by pushing or pulling the main frame 1, the traveling wheels 13 come into contact with the ground and roll, allowing the entire first concrete chute truck to move flexibly on the ground and easily move it to different construction locations.

[0053] When concrete conveying operations are required, the main frame 1 is moved to the designated position, ensuring that the bottom frame 11 is placed stably on the ground and the vertical frame 12 remains vertical, providing stable support for the receiving bin 2 and other components.

[0054] Please see Figure 7 As shown, in another preferred embodiment of this utility model, a support beam is also horizontally connected to the side of the main frame 1 away from the connecting frame 411.

[0055] The support beam is usually firmly fixed to the designated position of the main frame 1 by welding, bolting or other means to ensure that it forms an integral structure with the main frame 1. The support beam can also be used to increase the overall stability of the main frame 1.

[0056] Please see Figure 1 As shown, considering the convenience of manufacturing concrete chute trucks, the main frame 1, the first sub-frame 7, and the second sub-frame 8 in this embodiment are basically similar in structure, except that the receiving bin 2 and the manual opening and closing valve 3 are not required on the top of the first sub-frame 7 and the second sub-frame 8. In this way, the height of the first sub-frame 7 and the second sub-frame 8 is lower than that of the main frame 1, reducing the manufacturing material cost.

[0057] Correspondingly, the structures of the first chute assembly 4, the second chute assembly 5, and the third chute assembly 6 are basically the same.
