Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, specifically to a rapid unloading device for concrete transport tank trucks. Background Technology

[0002] With the construction industry developing at a rocket-like pace, the demand for concrete has exploded. Traditional transportation methods have quickly become inadequate, failing to meet the requirements of large-scale, high-efficiency construction. Concrete mixer trucks have ushered in a new era of construction transportation. They cleverly incorporate a rotary mixing device on the tank, maintaining mixing throughout the transportation process to ensure that the concrete arrives at the construction site with excellent performance and in good condition.

[0003] Currently, some existing concrete truck unloading devices use a single pushing or distributing method for unblocking. When the concrete experiences varying degrees of blockage, it is difficult to respond flexibly, resulting in a slow or even halted unloading process. In view of this, we propose a rapid unloading device for concrete trucks. Utility Model Content

[0004] The main objective of this invention is to provide a rapid unloading device for concrete transport trucks, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a rapid unloading device for concrete transport trucks, comprising a vehicle body, a tank body mounted on the vehicle body, a support frame fixedly connected to the vehicle body, and an adjustment structure mounted on the support frame. The adjustment structure includes:

[0006] An electric cylinder base is fixedly connected to the outer wall of the support frame, and a guide column is fixedly connected to the outer wall of the support frame;

[0007] A lifting plate is fixedly connected to the output end of the electric cylinder base, and a mounting rod is fixedly connected to the bottom of the lifting plate;

[0008] A hexagonal nut is threaded onto the outer wall of the mounting rod, and a drain block is sleeved on the outer wall of the mounting rod;

[0009] A hinge rod is hinged to the top of the lifting plate, and a fixing block is hinged to the end of the hinge rod away from the lifting plate. A drain rod is fixedly connected to the outer wall of the fixing block.

[0010] Preferably, the inner wall of the lifting plate is slidably connected to the outer wall of the guide column, and two sets of guide columns are provided, which are used to lift the lifting plate by means of an electric cylinder seat.

[0011] Preferably, a feeding hopper is fixedly connected to the inner wall of the support frame, and a receiving hopper is fixedly connected to the inner wall of the support frame.

[0012] Preferably, the outer wall of the unclogging rod is slidably connected to the inner wall of the feeding hopper, and the outer wall of the unclogging rod is slidably connected to the inner wall of the support frame.

[0013] Preferably, the support frame is provided with an adjustment component, the adjustment component includes a support arm, the inner wall of the support arm is rotatably connected to a synchronous shaft, and the top of the synchronous shaft is fixedly connected to a hopper.

[0014] Preferably, a synchronization disc is fixedly connected to the outer wall of the synchronization shaft, an adjustment seat is fixedly connected to the top of the support arm, a fixing rod is slidably connected to the inner wall of the adjustment seat, and an actuating disc is fixedly connected to the top of the fixing rod.

[0015] This utility model provides a rapid unloading device for concrete transport trucks. It has the following beneficial effects:

[0016] (1) The concrete transport truck rapid unloading device drives the lifting plate through the electric cylinder base to drive the mounting rod and the unblocking block to move up and down reciprocally. When descending, the bottom plane of the unblocking block pushes the material; when rising, the top inclined plane divides the material, realizing the dual-mode switching of pushing / dividing. This effectively solves the problem of low unloading efficiency caused by the traditional unloading device relying on only a single action to unblock, greatly improving the unblocking capacity of concrete during the unloading process and ensuring smooth unloading.

[0017] (2) The concrete truck rapid unloading device can move the fixed bar away from the directional hole by moving the dial, thereby releasing the limit on the synchronous disc, so that the synchronous disc can be rotated easily, driving the synchronous shaft and the unloading hopper to rotate synchronously, and changing the concrete unloading position. Compared with some existing devices with fixed unloading positions, it greatly improves the adaptability of the device and meets the needs of different unloading scenarios.

[0027] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0029] Please see Figures 1-7This utility model proposes a rapid unloading device for a concrete transport truck, including a vehicle body 1, a tank body 2 mounted on the vehicle body 1, and a support frame 3 fixedly connected to the vehicle body 1. The vehicle body 1, tank body 2, and support frame 3 are existing technologies and will not be described in detail. A feeding hopper 5 is fixedly connected to the inner wall of the support frame 3, and the outlet of the feeding hopper 5 is located inside the tank body 2, allowing material to enter the tank body 2 through the feeding hopper 5. A receiving hopper 6 is fixedly connected to the inner wall of the support frame 3, located below the tank body 2. When the tank body 2 discharges material, the concrete can fall into the receiving hopper 6 and then onto the discharge hopper 73. An adjustment structure 4 is provided on the support frame 3, including an electric cylinder base 41. The electric cylinder base 41 is fixedly connected to the outer wall of the support frame 3, and a guide column is fixedly connected to the outer wall of the support frame 3. 42. A lifting plate 43 is fixedly connected to the output end of the electric cylinder base 41. The lifting plate 43 is raised and lowered by the electric cylinder base 41. The inner wall of the lifting plate 43 is slidably connected to the outer wall of the guide column 42. Two sets of guide columns 42 are provided to guide the lifting plate 43. An installation rod 44 is fixedly connected to the bottom of the lifting plate 43. A hexagonal nut 45 is threadedly connected to the outer wall of the installation rod 44. The installation rod 44 has some threads, and the hexagonal nut 45 is threadedly connected to the threads. A drain block 46 is sleeved on the outer wall of the installation rod 44. Two sets of hexagonal nuts 45 are provided and distributed on both sides of the drain block 46. The top of the drain block 46 has a slope, while the bottom is flat. The drain block 46 is fixed by the two sets of hexagonal nuts 45.

[0030] In this utility model, the lifting plate 43 drives the mounting rod 44 to move synchronously, so that the unblocking block 46 can perform unblocking work in the receiving hopper 6. When the unblocking block 46 descends, the bottom plane of the unblocking block 46 pushes the concrete to facilitate the concrete leaving the receiving hopper 6. When the unblocking block 46 rises, the inclined surface at the top of the unblocking block 46 distributes the concrete. By switching between pushing and distributing modes, the problem of low unblocking efficiency of single action is solved, and the unblocking efficiency is improved. The top of the lifting plate 43 is hinged to a hinge rod 47, and the end of the hinge rod 47 away from the lifting plate 43 is hinged to a fixing block 48. The outer wall of the fixing block 48 is fixedly connected to an unblocking rod 49. When the lifting plate 43 moves back and forth, the hinge rod 47 will drive the fixing block 48 to move. The movement of the fixing block 48 will drive the unblocking rod 49 to slide on the support frame 3, so that the unblocking rod 49 will move back and forth in the feeding hopper 5 to perform unblocking work in the feeding hopper 5.

[0031] Furthermore, the outer wall of the unclogging rod 49 is slidably connected to the inner wall of the feeding hopper 5, and the outer wall of the unclogging rod 49 is slidably connected to the inner wall of the support frame 3. The support frame 3 is provided with an adjustment component 7, which includes a support arm 71. A synchronous shaft 72 is rotatably connected to the inner wall of the support arm 71. A feeding hopper 73 is fixedly connected to the top of the synchronous shaft 72. A synchronous disc 74 is fixedly connected to the outer wall of the synchronous shaft 72. An adjustment seat 75 is fixedly connected to the top of the support arm 71. A fixing rod 76 is slidably connected to the inner wall of the adjustment seat 75. A lever is fixedly connected to the top of the fixing rod 76. The moving disc 77 and the synchronous disc 74 have directional holes. The fixing rod 76 can pass through the directional holes. By making the fixing rod 76 pass through the adjusting seat 75 and the synchronous disc 74 at the same time, the synchronous disc 74 is fixed, and the angle of the hopper 73 is fixed. The adjusting seat 75 and the actuating disc 77 are elastically connected by a compression spring. By moving the actuating disc 77, the fixing rod 76 is driven away from the directional hole, releasing the limiting state of the synchronous disc 74, which makes it convenient to rotate the synchronous disc 74, drive the synchronous shaft 72 and the hopper 73 to rotate synchronously, and make it convenient to change the position of the concrete discharge.

[0032] During use, the lifting plate 43 is reciprocated and raised by the electric cylinder base 41 during the unloading process. The lifting plate 43 drives the mounting rod 44 to move up and down synchronously, causing the unblocking block 46 to reciprocate and raise. When the unblocking block 46 descends, the bottom plane of the unblocking block 46 pushes the concrete to facilitate the concrete leaving the receiving hopper 6. When the unblocking block 46 rises, the inclined surface at the top of the unblocking block 46 divides the concrete. By switching between the pushing and dividing modes, the problem of low unblocking efficiency of single action is solved, and the unblocking efficiency is improved.

[0033] When the device is feeding, in order to prevent the material from clogging the feeding hopper 5, we can start the electric cylinder base 41 to make the lifting plate 43 reciprocate. In conjunction with the hinge rod 47, the fixed block 48 will move. The movement of the fixed block 48 will cause the unblocking rod 49 to slide on the support frame 3, so that the unblocking rod 49 will reciprocate in the feeding hopper 5 to unblock the feeding hopper 5.

[0034] By moving the actuating disc 77, the fixed rod 76 is driven away from the directional hole, releasing the limiting state of the synchronous disc 74, making it convenient for us to rotate the synchronous disc 74, driving the synchronous shaft 72 and the discharge hopper 73 to rotate synchronously, making it convenient for us to change the position of concrete discharge and improving the adaptability of the device.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
