Technical Field

[0001] The utility model relates to the technical field of mixer trucks, in particular to a discharging system of a mixer truck. Background Art

[0002] The discharging system of an existing concrete mixer truck (referred to as a mixer truck) is mainly used to guide the concrete material in the mixer truck to the outside. The existing mixer truck discharging system mainly consists of a discharging hopper, an open metal sliding hopper, a support arm, a locking support arm, a telescopic adjustment rod, etc. After the concrete flows out of the tank body, it is collected by the discharging hopper and flows into the sliding hopper below from the outlet below the discharging hopper. The sliding hopper is fixed under the discharging hopper by the support arm, with a rotating shaft mechanism in the middle to adjust the angle. The telescopic adjustment rod adjusts the tilt angle, and the locking support arm locks the position of the sliding hopper to guide the concrete to the place where it needs to be discharged. However, the existing mixer truck discharging system has the following technical problems:

[0003] 1. The existing mixer truck discharging system consists of a discharging hopper, a sliding hopper, a support arm, a locking arm, a telescopic adjustment rod, etc., which has a complex structure, a bulky structure and high cost;

[0004] 2. Before unloading concrete, the angle of the sliding hopper needs to be adjusted to the position where the concrete needs to be unloaded by using the support arm, locking arm and telescopic adjustment rod. This process is complicated and time-consuming.

[0005] 3. The open structure of the sliding hopper is prone to concrete leakage during the unloading process, causing the concrete to spill everywhere;

[0006] 4. During the concrete unloading process, some concrete will stick to the metal slide hopper, which is not easy to clean. Utility Model Content

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0027] Reference Figures 1 to 2 The utility model provides a discharging system for a mixer truck, comprising: a tank body 1, a mixing drum, a discharging hopper 2, a rubber hose 3, a control system and a fixed rope hook 6;

[0028] The mixing drum is arranged inside the tank body 1, and the control system is connected to the mixing drum for controlling the mixing drum;

[0029] A concrete outlet is provided at the rear end of the tank body 1, and the discharge hopper 2 is fixed to the outside of the tank body 1, and the feed port of the discharge hopper 2 is located below the concrete outlet. One end of the rubber hose 3 is installed at the discharge port of the discharge hopper 2, and a traction part 3-1 is provided on the outer side wall of the other end of the rubber hose 3. The traction part 3-1 is provided with an opening, and the hook at one end of the fixed rope hook 6 is hung on the opening of the traction part 3-1.

[0030] Among them, in this application, it is necessary to control the rotation of the mixing drum through a control system so that the concrete in the tank body 1 is discharged from the concrete outlet and falls into the discharge hopper 2, and then falls from the discharge hopper 2 into the rubber hose 3 and falls at a preset position; the tank body 1, the mixing drum (not shown in the figure) and the control system (not shown in the figure) are all existing technologies, and their specific structure and working principle will not be described in detail here.

[0031] It should be noted that the amount of concrete discharged is the largest when the rubber hose 3 of the present application is in a vertical state. When the vertical line is used as the center line, the greater the angle at which the other end of the rubber hose 3 swings to the left or right, the smaller the amount of concrete discharged.

[0032] When the unloading position is on the ground or the pump truck receiving hopper 5 is just above the rubber hose 3, there is no need to adjust the inclination of the rubber hose 3. At this time, the rubber hose 3 is set vertically. The operator controls the mixing drum to rotate so that the concrete in the tank body 1 is discharged from the concrete outlet and falls into the discharge hopper 2. Then, it falls from the discharge hopper 2 into the rubber hose 3 and directly falls on the ground or the receiving port of the pump truck receiving hopper 5.

[0033] When the unloading position is around the rubber hose 3, that is, the pump truck receiving hopper 5 is not located directly above the rubber hose 3, it is necessary to adjust the inclination of the rubber hose 3. At this time, the rubber hose 3 is connected to the pump truck receiving hopper 5 through the fixed rope hook 6, and the other end of the rubber hose 3 is aligned with the receiving port of the pump truck receiving hopper 5, and the unloading operation can be carried out;

[0034] Specifically, the material receiving hopper 5 of the pump truck includes a material receiving hopper 5-1 and a material receiving handle 5-2; the material receiving handle 5-2 is fixedly arranged on one side above the material receiving hopper 5-1, and the material receiving handle 5-2 is arranged away from the rubber hose 3, and the hook at one end of the fixed rope hook 6 is hung on the opening of the traction part 3-1, and the rope body of the fixed rope hook 6 passes above the material receiving hopper 5-1, and the other end of the fixed rope hook 6 is tied to the material receiving device 5 to align the rubber hose 3 with the material receiving port of the material receiving hopper 5-1.

[0035] Optionally, one end of the rubber hose 3 is sleeved and installed at the discharge port of the discharge hopper 2 , and a hoop 4 is sleeved on one end of the rubber hose 3 to fix the rubber hose 3 on the discharge hopper 2 .

[0036] Among them, the rubber hose 3 can be fixed on the discharge hopper 2 only by the hoop 4. When the rubber hose 3 needs to be replaced, the hoop 4 can be directly loosened to remove the rubber hose 3. The operation is simple and easy to replace. Moreover, the rubber hose 3 used in this application is low in price, which can reduce the cost of use.

[0037] Optionally, the cross section of the rubber hose 3 is circular or elliptical.

[0038] Among them, when the cross-section of the rubber hose 3 is circular, the shape of the discharge port of the discharge hopper 2 is also circular, and the cross-sectional shape of the rubber hose 3 is adapted to the shape of the discharge port of the discharge hopper 2, which is convenient for installation; when the cross-section of the rubber hose 3 is elliptical, the shape of the discharge port of the discharge hopper 2 is also elliptical, and the cross-sectional shape of the rubber hose 3 is adapted to the shape of the discharge port of the discharge hopper 2, which is convenient for installation; therefore, in this application, the cross-sectional shape of the rubber hose 3 can be selected according to the shape of the discharge port of the discharge hopper 2, which has wide versatility.

[0039] Optionally, the diameter of the rubber hose 3 is 0.4 m-0.5 m.

[0040] Among them, the limitation of the diameter size of the rubber hose 3 can make the rubber hose 3 of this size fully discharge the concrete. If the size of the rubber hose 3 is too large, it is inconvenient to operate. If the diameter size of the rubber hose 3 is too small, the concrete cannot be fully discharged, the discharge time is long, and the efficiency is low.

[0041] Optionally, the length of the rubber hose 3 is 1.2 m-1.5 m.

[0042] Among them, the length of the rubber hose 3 is limited so that when the unloading position is on the ground, the hose is at a certain distance from the inside, so that the rubber hose 3 is not too close to the ground, causing the concrete to be unable to be discharged. It is also necessary to adjust the inclination angle of the other end of the rubber hose 3 or move the position of the mixer truck, which is troublesome to operate.

[0043] Working principle:

[0044] When the unloading position is the ground or the pump truck receiving hopper 5 is directly below the rubber hose 3, there is no need to adjust the inclination angle of the rubber hose 3. The rubber hose 3 is in a vertical state. The control system controls the rotation of the mixing drum so that the concrete in the tank body 1 flows out from the concrete outlet and falls into the discharge hopper 2. Then, it falls from the discharge hopper 2 into the rubber hose 3 and falls on the ground or the pump truck receiving hopper 5 to complete the unloading of the concrete.

[0045] When the unloading position is the pump truck receiving hopper 5 and the pump truck receiving hopper 5 is not directly below the rubber hose 3, use the fixed rope hook 6, hook one end of the fixed rope hook 6 on the opening of the traction part 3-1, and tie the other end of the fixed rope hook 6 to the pump truck receiving hopper 5. At this time, the rubber hose 3 is aligned with the receiving hopper of the pump truck receiving hopper 5, and the control system controls the rotation of the mixing drum so that the concrete in the tank body 1 flows out from the concrete outlet and falls into the discharge hopper 2, and then falls from the discharge hopper 2 into the rubber hose 3 and falls into the pump truck receiving hopper 5 to complete the unloading of the concrete.

[0046] It should be noted that not all steps and modules in the above processes and system structure diagrams are required, and certain steps or modules can be omitted according to actual needs. The execution order of each step is not fixed and can be adjusted as needed. The system structure described in the above embodiments can be a physical structure or a logical structure, that is, some modules may be implemented by the same physical entity, or some modules may be implemented by multiple physical entities, or may be implemented by certain components in multiple independent devices.
