Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0028] The core of the present application is to provide an additive adding device, which effectively lifts the liquid additive to the filling height by using a pump body, and the operation point of the control module is arranged at the top and bottom of the climbing ladder, so that the operator can directly control the pump body to fill the additive after observing the situation in the mixing tank at the top of the climbing ladder, and the pump body can also be controlled at the bottom of the climbing ladder to draw clean water to flush the whole device, avoiding the corrosion of the additive on the whole device, effectively improving the convenience of additive filling.
[0029] Another core of the present application is to provide a concrete mixer truck comprising the above-mentioned additive adding device, which has the same technical features and can solve the same technical problems.
[0030] Please refer to Figure 1 and Figure 2An admixture adding device for adding admixtures to a concrete mixer truck, comprising:
[0031] Pump body 1 is fixedly installed relative to the mixer truck. The water inlet end of pump body 1 is provided with water inlet pipe 3 for connecting to the admixture supply source. The water outlet end of pump body 1 is provided with water outlet pipe 2, which is connected to the water inlet end of the hopper 7 of the mixer truck.
[0032] The control module is electrically connected to the control terminal of the pump body 1. The control module has several sets of operating points, at least one set of operating points is close to the top of the climbing ladder 5 at the rear of the mixer truck, and at least one set of operating points is close to the bottom of the climbing ladder 5.
[0033] like Figure 1 As shown, an admixture adding device is installed at the rear end of the concrete mixer truck. The main body of the admixture adding device is a pump body 1, which is fixedly installed at the rear of the chassis beam of the mixer truck and electrically connected to the power supply system of the mixer truck. The power supply system of the mixer truck is used for power supply. A water outlet pipe 2 connects the water outlet of the pump body 1 and the water inlet of the hopper 7. A water inlet pipe 3 connects the water inlet of the pump body 1 and the admixture supply source. Two sets of control module operation points are set up. One set of operation points is located at the top of the climbing ladder 5, and the other set of operation points is located at the bottom of the climbing ladder 5.
[0034] The operating logic of the admixture addition device is as follows: When the mixer truck is transporting concrete or after arriving at the destination, the construction personnel will assess the concrete in the mixing tank. If it is determined that admixtures need to be added, the operator can move the admixture supply source to the rear of the truck, connect the water inlet pipe 3 to the admixture supply source, and move to the vicinity of the hopper 7 via the climbing ladder 5. The operator can observe the quality of the concrete in the mixing tank through the filling port of the hopper 7 and operate the control module at the top of the climbing ladder 5 to turn on the switch of the pump body 1. The pump body 1 starts to work, and the admixture is sucked into the pump body 1 through the water inlet pipe 3 and then sent to the water inlet of the hopper 7 through the water outlet pipe 2. The admixture flows into the mixing tank through the hopper 7. At the same time, the mixing tank is kept rotating rapidly to mix the concrete in the mixing tank. During the admixture addition process, the operator can stand at the top of the climbing ladder 5 and observe the concrete in the mixing tank through the filling port of the hopper 7.
[0035] When the concrete quality meets the requirements, the operator can manipulate the control module at the top of the climbing ladder 5 to turn off the switch of the pump body 1 and stop the addition of admixtures.
[0036] Additives are corrosive chemical agents. After addition, the injection pipeline needs to be cleaned to ensure the long-term use of the equipment.
[0037] When the admixture adding device is cleaned, the original admixture supply source can be replaced by a clean water tank, the operator directly stands on the ground, manipulates the control module at the bottom of the climbing ladder 5, opens the switch of the pump body 1, and clean water enters the pipeline for cleaning, so as to avoid that the admixture stays in the admixture adding device for a long time and causes corrosion of the pump body 1 or the pipeline.
[0038] In some embodiments, the control module is two sets of switches that are interlocked, one set of switches is fixedly arranged at the top end of the climbing ladder 5, and the other set of switches is fixedly arranged at the bottom end of the climbing ladder 5.
[0039] The control module adopts two sets of switches that are interlocked, directly controls the pump body 1, and the two sets of switches can control the pump body 1 at the same time and are interlocked, so as to avoid confusion of the control logic of the pump body 1, and the control module that is interlocked can effectively simplify the control logic and reduce the use cost.
[0040] In some embodiments, the control module is a handheld controller, and the handheld controller is electrically connected to the control end of the pump body 1 through wired transmission or wireless transmission.
[0041] The handheld controller can obtain more operation points, and the operator can control the pump body 1 at multiple positions, and the handheld controller with wireless connection can break away from the restriction of the wire harness on the operation points, so that the control module has stronger flexibility.
[0042] In some embodiments, the water inlet end of the pump body 1 is further provided with an auxiliary water inlet pipe 4, and the auxiliary water inlet pipe 4 is communicated with the water supply system of the mixing truck.
[0043] The auxiliary water inlet pipe 4 is added, so that the admixture adding device can be directly connected to the water supply system of the mixing truck, and after the admixture is filled, the water storage of the water supply system can be used to flush the admixture adding device, thereby improving the use convenience of the device.
[0044] In some embodiments, a control valve 6 is further included and connected in series in the auxiliary water inlet pipe 4.
[0045] The control valve 6 is added in the auxiliary water inlet pipe 4, so that the communication between the admixture adding device and the water supply system of the mixing truck can be manually cut off, and the effect of the water pressure in the water supply system of the mixing truck on the pump body 1 is avoided.
[0046] However, before the admixture adding device is flushed, the control valve 6 should be opened first, so that the pump body 1 is communicated with the water supply system of the mixing truck, the pump body 1 can draw the water storage in the water supply system, and then flush the admixture adding device. The waste water generated by flushing still enters the hopper 7 through the water outlet pipe 2 and then enters the mixing tank.
[0047] In some embodiments, a water mixing valve is further included, two water inlet ends of the water mixing valve are communicated with the water inlet pipe 3 and the auxiliary water inlet pipe 4 respectively, and a water outlet end of the water mixing valve is communicated with the water inlet end of the pump body 1.
[0048] By adding the water mixing valve, the pump body 1 can simultaneously extract liquid from the admixture supply source and the vehicle-mounted water supply system through the water inlet pipe 3 and the auxiliary water inlet pipe 4 respectively, i.e. the admixture is extracted from the admixture supply source, and the clean water is extracted from the vehicle-mounted water supply system, the clean water is mixed with the admixture, and then is added to the hopper 7 and the mixing tank through the water outlet pipe 2, and is mixed with the concrete in the mixing tank, and by adjusting the water mixing ratio of the water mixing valve, the mixing ratio of the clean water and the admixture can be adjusted, so that the admixture does not need to be diluted in advance before being added, the difficulty of adding the admixture is reduced, and the adding efficiency is improved.
[0049] In some embodiments, a check valve is further included, which is connected in series at the water inlet end communicated with the auxiliary water inlet pipe 4 of the water mixing valve, so as to prevent the admixture from entering the vehicle-mounted water supply system through the water mixing valve.
[0050] It is worth noting that since the clean water in the vehicle-mounted water supply system cannot enter the water inlet pipe 3 under the action of the pump body 1, after the admixture is added, the water inlet pipe 3 should be communicated with the clean water source, and then the pump body 1 is started to flush the water mixing valve and the water inlet pipe 3, so as to prevent the admixture from remaining in the water mixing valve and the water inlet pipe 3.
[0051] In some embodiments, a solvent bucket and a fixing mechanism for fixing the solvent bucket are further included, the solvent bucket is used for storing and supplying the admixture, and the fixing mechanism is fixed relative to the concrete mixer truck.
[0052] In actual use, the driver of the concrete mixer truck will carry one or more water buckets as the solvent bucket to store or dilute the admixture.
[0053] In addition, the pump body 1 is preferably but not limited to an impeller pump and a plunger pump, and the water outlet pipe 2, the water inlet pipe 3 and the auxiliary water inlet pipe 4 are preferably but not limited to rubber pipes, plastic pipes and PVC pipes.
[0054] In addition to the admixture adding device disclosed in the above embodiments, the utility model further provides a concrete mixer truck including the admixture adding device, and the structures of other parts of the concrete mixer truck can refer to the prior art, which will not be described herein.
[0055] The embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same or similar parts of each embodiment can be referred to each other.
[0056] The above has carried out the detailed introduction to the admixture adding device and the concrete mixer truck provided by the utility model. The principle and implementation mode of the utility model are described by applying specific examples in this paper, and the above embodiment description is only used for helping to understand the method and core idea of the utility model.
