Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a concrete on-site bin-type dynamic intelligent weighing device. Background Art

[0002] The on-site measurement of concrete mainly uses a weighbridge for weighing. To accurately measure the pouring volume of concrete, the concrete transport vehicle needs to be weighed once when entering and leaving the site. However, at present, general construction sites use spot-check methods, and sometimes the concrete transport vehicle is only weighed once when entering the site, resulting in a large amount of concrete loss, causing significant economic losses and incorrect calculation of the concrete pouring volume, and unable to accurately measure. Content of the Utility Model

[0003] The purpose of the utility model is to provide a concrete on-site bin-type dynamic intelligent weighing device to solve the problem of accurately measuring the concrete volume of the concrete transport vehicle discharging on-site.

[0012] Furthermore, for the concrete on-site bin-type dynamic intelligent weighing device provided by the utility model, the bin body is an open trough shape.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The in-situ concrete bin-type dynamic intelligent weighing device provided by the utility model can unload the concrete slurry in the concrete transport vehicle into multiple weighing bins for bin filling and automatically weigh the filled weighing bins. After calculating the total weight, the concrete volume unloaded by the concrete transport vehicle is calculated according to the formula of volume = weight / density, so as to measure the concrete volume unloaded by the concrete transport vehicle on site, improve the accuracy of the concrete volume measurement during the unloading of the concrete transport vehicle, and avoid the problems of major economic losses caused by the failure to unload, incomplete unloading of the concrete transport vehicle, and only weighing when entering the site but not weighing when leaving the site, resulting in concrete loss and measurement errors.

[0026] The following describes the present utility model in detail with reference to the accompanying drawings: According to the following description, the advantages and features of the present utility model will be clearer. It should be noted that the drawings are all in a very simplified form and use non-precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present utility model.

[0027] Please refer to Figures 1 to 6 , an embodiment of the present utility model provides a concrete on-site bin-type dynamic intelligent weighing device 100, including:

[0028] A conveyor belt mechanism 110, which is arranged horizontally or inclined relative to the horizontal plane. Among them, the conveyor belt mechanism 110 can adopt any known technology, including but not limited to a drive shaft 111 and a conveyor belt 112 in the shape of an endless track driven by it, that is, only two key components, the drive shaft 111 and the conveyor belt 112, constituting the conveyor belt mechanism 110 are exemplified in the figure. The conveyor belt can be a rubber belt structure or a chain structure. Among them Figure 2 An inclined conveyor belt mechanism 110 relative to the horizontal plane is exemplified, Figure 1 A horizontally arranged conveyor belt mechanism 110 is exemplified, Figure 3 Two conveyor belts 112 with a chain structure are exemplified in

[0029] Weighing bins 120, which are multiple and are arranged around the conveyor belt mechanism 110. The weighing bin 120 includes a bin body 121 and a weighing meter 122 thereon. The weighing meter 122 is located at the bottom of the bin body 121. When the conveyor belt 112 is a chain structure, there are more than two to enable the weighing bin 120 to run smoothly on the conveyor belt mechanism 110.

[0030] Please refer to Figures 1 to 2 , an embodiment of the present utility model also provides a concrete on-site bin-type dynamic intelligent weighing method. By using the above-mentioned concrete on-site bin-type dynamic intelligent weighing device 100, the following steps can be included:

[0031] Step 401, arrange the concrete on-site bin-type dynamic intelligent weighing device 100 at the concrete pumping truck, and align the pumping chute 300 of the concrete pumping truck below the discharge end of the conveyor belt mechanism 110.

[0032] Step 402, park the concrete transport vehicle at the concrete on-site bin-type dynamic intelligent weighing device 100, and align the chute 200 of the concrete transport vehicle with the weighing bin 120 at the filling end of the conveyor belt mechanism 110.

[0033] Step 403: Discharge the concrete slurry in the concrete transport vehicle into the aligned weighing bin 120 through the chute 200. When the weighing bin 120 is filled up to the maximum limit at most, stop filling the current weighing bin 120, start the conveyor belt mechanism 110 to move the filled weighing bin 120 forward, move the next empty weighing bin 120 to the filling end and align it with the chute 200 position of the concrete transport vehicle as the current weighing bin 120, and continue to fill the current weighing bin 120 through the chute 200. After all the concrete slurry in the concrete transport vehicle is discharged, when the weighing bin 120 filled with concrete slurry is stable on the conveyor belt mechanism 110, use the weighing meter 122 to read the weight of the concrete slurry in each stable weighing bin 120 respectively and calculate the total weight, and calculate the cubic meters of concrete discharged by the concrete transport vehicle according to the formula volume = weight / density, where the volume is in cubic meters. Among them Figures 1 to 2 12 weighing bins 120 are exemplified. 4 are arranged above the conveyor belt 112, 4 are arranged below, and 2 are arranged at each of the two end corners, but it is not limited to this. At this time, the weight of the weighing bin 120 above the conveyor belt 112 at the discharge end that is not currently being filled with concrete slurry can be read. Since there is an impact force when the weighing bin 120 being filled with concrete slurry is filled through the chute 200, the weighing is inaccurate at this time, so the weighing bin 120 being filled with concrete slurry is not read to avoid measurement errors.

[0034] In step 403, after the weighing bin 120 filled with concrete slurry is weighed, it can be continuously conveyed forward to the discharge end through the conveyor belt mechanism 110 and turned down at the corner of the conveyor belt mechanism 110 to discharge into the pumping chute 300 for use by the concrete pump truck. At this time, the concrete slurry discharged by one concrete transport vehicle can be weighed and discharged immediately by moving the position directly through the conveyor belt mechanism 110 to the discharge end after weighing, or after all the concrete slurry of one concrete transport vehicle is unloaded and filled in multiple weighing bins 120, it can be continuously moved through the conveyor belt mechanism 110 to the discharge end in sequence to discharge into the pumping chute 300.

[0035] The on-site concrete bin-type dynamic intelligent weighing device 100 provided by the embodiment of the utility model is composed of a conveyor belt mechanism 110 and a plurality of weighing bins 120 arranged around the conveyor belt mechanism 110, and has the advantages of simple structure, convenient transmission, filling and discharging control of the weighing bins 120. The conveyor belt mechanism 110 is arranged obliquely relative to the horizontal plane, which can change the heights of the weighing bins 120 at the filling end and the discharging end, so as to facilitate the filling of the weighing bin 120 at the filling end by a concrete transport vehicle through a chute 200, and facilitate the downward turning and discharging of the weighing bin 120 at the discharging end along the corner of the conveyor belt 112 into a pumping chute 300 of a concrete pumping vehicle, meeting the matching layout requirements of the concrete transport vehicle and the concrete pumping vehicle at the construction site. The concrete transport vehicle is a concrete mixer truck.

[0036] The on-site concrete bin-type dynamic intelligent weighing device 100 and method provided by the embodiment of the utility model can discharge the concrete slurry in the concrete transport vehicle into a plurality of weighing bins 120 for bin filling and automatically weigh the filled weighing bins 120. After calculating the total weight, the concrete volume discharged by the concrete transport vehicle is calculated according to the formula of volume = weight / density, so as to measure the concrete volume discharged by the concrete transport vehicle on site, improve the accuracy of the concrete volume measurement during the discharging of the concrete transport vehicle, and avoid the problems of significant economic losses caused by the loss of concrete slurry and measurement errors due to the non-discharging, incomplete discharging of the concrete transport vehicle, and only weighing when entering the site and not weighing when leaving the site.

[0037] Please refer to Figures 1 to 2 , in order to ensure the stability of each weighing bin 120 during the circular transmission movement on the conveyor belt mechanism 110, the on-site concrete bin-type dynamic intelligent weighing device 100 and method provided by the embodiment of the utility model may further include:

[0038] An elastic member 130 is connected between two adjacent weighing bins 120. By connecting two adjacent weighing bins 120 through the elastic member 130, when the weighing bins 120 are transmitted and moved on the upper and lower surfaces of the conveyor belt 112 of the conveyor belt mechanism 110, the elastic member 130 is in a reset state, reducing the gap between two adjacent weighing bins. At the corners at both ends of the conveyor belt 112, since the gap between the two weighing bins 120 becomes larger, the elastic member 130 is in a stretched state at this time, so as to ensure the stability of the connection between two adjacent weighing bins 120, improve the integrity of the 12 weighing bins 120 on the conveyor belt 112, and avoid the risk of tipping over. That is, all the weighing bins 120 on the conveyor belt 112 are connected to each other in pairs through the elastic member 130.

[0039] To prevent the concrete slurry discharged from the chute 200 from leaking outside the weighing bin 120 during the switching of the weighing bins 120, which may pollute the environment or leak onto the conveyor belt 112 and affect the transmission performance of the conveyor belt mechanism 110, for the concrete on-site bin-divided dynamic intelligent weighing device 100 and method provided by the embodiments of the present invention, the elastic member 130 is rubber or other stretchable flexible materials. At this time, since the rubber is a continuous body without gaps, the leaked slurry is supported by the rubber, thereby protecting the conveyor belt 112 and preventing the slurry from leaking outside the device 100 to pollute the environment.

[0040] To ensure the stable connection between the weighing bins 120 and the integrity of all the weighing bins 120 on the conveyor belt 112, for the concrete on-site bin-divided dynamic intelligent weighing device 100 and method provided by the embodiments of the present invention, the elastic member 130 can be a spring. The spring is a tension spring, and each connection node is not limited to one.

[0041] To weigh the concrete slurry in the bin body 121, for the concrete on-site bin-divided dynamic intelligent weighing device 100 and method provided by the embodiments of the present invention, the weighing meter 122 can be a force measuring sensor such as a pressure sensor. The pressure sensor can be placed on the inner surface of the bottom of the bin body 121, embedded in the bottom of the bin body 121, or placed on the outer surface of the bottom of the bin body 121.

[0042] Please refer to Figures 4 to 6 , to facilitate the filling of the concrete slurry, for the concrete on-site bin-divided dynamic intelligent weighing device 100 and method provided by the embodiments of the present invention, the bin body 121 can be an open trough shape, that is, the cross-sectional shape of the bin body 121 is an inverted trapezoid.

[0043] The present invention is not limited to the above specific embodiments. Obviously, the above-described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention. Those skilled in the art can make other levels of modifications and changes to the present invention. Thus, if these modifications and changes of the present invention are within the scope of the claims of the present invention, the present invention also intends to include these modifications and changes.
