DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] In the present device, the so-called rotational connection means that the bearing is baked and installed on the shaft, and a spring retaining ring groove is provided on the shaft or the shaft hole. The axial fixation of the bearing is achieved by clamping an elastic retaining ring in the retaining ring groove to achieve rotation; the so-called hinged connection means a connection method that is movable on connecting parts such as hinges, pin shafts, and short shafts.

[0020] The present utility model will be described in detail below with reference to the accompanying drawings.

[0021] Embodiment 1:

[0022] The following combines the attached Figures 1-4This embodiment describes a precast concrete unit weight detection device, including: a mixing device 1, a sampling pipe 2 is connected to the side wall within the maximum mixing volume range of the mixing device 1, a concrete pump 3 is provided in the middle of the sampling pipe 2, the end of the sampling pipe 2 is connected to a scraper 4, the lower surface of the scraper 4 is in contact with the upper edge of the unit weight container 5, the unit weight container 5 is located on the upper surface of a mass sensor 6, the upper surface of the mass sensor 6 is connected to a clamping strip 7, the clamping strip 7 is slidably connected to a clamping groove 8 on the lower surface of the unit weight container 5, the lower surface of the mass sensor 6 is connected to a turntable 9, the shaft end of the turntable 9 is rotatably connected to a frame 10, the frame 10 is connected to the sides of the mixing device 1 and the concrete pump 3, and the shaft end of the turntable 9 is connected to a power mechanism 11;

[0023] When the concrete is being mixed, the concrete pump 3 is turned on, and the concrete pump 3 transports the concrete in the mixing device 1 to the unit weight container 5 through the sampling pipe 2. The power mechanism 11 is turned on, and the power mechanism 11 rotates the unit weight container 5 through the turntable 9, the mass sensor 6, and the clamping strip 7. After the unit weight container 5 is evenly filled with concrete, the concrete pump 3 is turned off, and the clamping strip 7 levels the upper part of the unit weight container 5. The excess concrete is thrown out under the centrifugal force during the rotation of the unit weight container 5. At this time, the reading of the mass sensor 6 divided by the unit weight container 5 is the real-time unit weight of the concrete. When replacing the unit weight container 5, it can be pulled out along the clamping strip 7, which is convenient and fast.

[0024] The lower surface of the scraper 4 is connected to a scraping blade 12, the scraping blade 12 is inclined and in contact with the outer side wall of the unit weight container 5, and the rotation direction of the turntable 9 is the same as the inclined direction of the scraping blade 12 from top to bottom;

[0025] When the unit weight container 5 rotates, the scraping blade 12 scrapes off the concrete adhering to the surface of the outer side wall of the unit weight container 5. The concrete that is scraped off but does not directly fall is guided to the lower part by the inclined scraping blade 12 and then drops, completing the cleaning.

[0026] Both ends of the clamping groove 8 are provided with chamfers;

[0027] It is convenient for the clamping strip 7 to slide in.

[0028] The axis of the sampling pipe 2 is not concentric with the unit weight container 5;

[0029] Concentricity will cause a cleaning dead angle for the scraper 4.

[0030] A through hole 13 is provided in the clamping strip 7, ball head sliders 14 are slidably connected to both ends of the through hole 13, a spring 15 in a compressed state is provided between the two ball head sliders 14, and a hemispherical groove 16 is provided on the inner wall of the clamping groove 8, and the ball head of the ball head slider 14 can coincide with the hemispherical groove 16;

[0031] When the ball head slider 14 contacts the inner wall of the card slot 8, the ball head slider 14 slides into the through hole 13. When the ball head slider 14 slides into the hemispherical groove 16, under the action of the spring 15, the ball head slider 14 is stuck into the hemispherical groove 16 to make the bulk density container 5 more stable and the cleaning effect better.

[0032] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.
