[0023] In order to make the objectives, technical solutions and beneficial effects of the present utility model clearer and more understandable, the technical solutions in the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] In the embodiment of the present utility model, as Figures 1 - 3 shown, the concrete sampling and storage device includes: a cylinder body 1, a sampling assembly and a storage assembly; the cylinder body 1 has a chamber 101 with an opening at the top; the sampling assembly includes a hopper 2 and a first cover body 3, and the hopper 2 and the first cover body 3 are respectively provided with a sampling chamber 201 and a discharge port 4 that are connected and communicated to form a sampling channel; the storage assembly includes a plurality of stirring blades 5 and a second cover body 6, and the plurality of stirring blades 5 are arranged at intervals and rotatably on the second cover body 6; wherein, the first cover body 3 and the second cover body 6 are selectively and detachably arranged on the cylinder body 1 to close the chamber 101 and make the hopper 2 protrude outside the chamber 101 or make the stirring blades 5 extend into the chamber 101.

[0025] Specifically, in the embodiment of the present utility model, the cylinder body 1 has a chamber 101 with an upward opening for containing concrete. In order to facilitate viewing the situation of the concrete in the chamber 101, at least part of the surface of the cylinder body 1 is transparent, that is: a visible window is provided on the surface of the cylinder body 1; of course, a scale line can also be provided on one side of the visible window.

[0026] In the embodiment of the present utility model, the collection assembly includes a hopper 2 and a first cover body 3. The hopper 2 is used to extend into the concrete for sampling; at the same time, the hopper 2 is formed with a sampling chamber 201 to transfer the concrete; and the first cover body 3 is provided with a discharge port 4, and the discharge port 4 is connected and communicated with the above-mentioned sampling chamber 201 to form a sampling channel through which the concrete can flow out. Covering the first cover body 3 on the cylinder body 1 can connect the sampling channel with the chamber 101, so that the concrete after sampling can flow into the chamber 101 through the sampling channel.

[0027] In the embodiment of the present utility model, the storage assembly includes a plurality of stirring blades 5 and a second cover body 6. Covering the second cover body 6 on the cylinder body 1 enables the stirring blades 5 to rotatably extend into the chamber 101 to stir the concrete therein. During the process of sending for inspection, the concrete can be prevented from hardening before arrival by the stirring of the stirring blades 5.

[0028] In this embodiment, two sets of devices, namely a sampling component and a storage component, are alternately installed at the cylinder body 1, so as to form a sampling device for sampling concrete and a storage device for storing concrete. When used as a sampling device, the hopper 2 is located outside the chamber 101. The hopper 2 is tilted so that the concrete enters the chamber 101 through the sampling channel for short-term storage. When used as a storage device, the rotation of the stirring blades 5 can stir the concrete located in the chamber 101 to prevent it from hardening. The same cylinder body 1 is used for loading and unloading concrete in the two devices. On the one hand, the transfer process between sampling and storage can be omitted, which can not only shorten the inspection time, but also reduce the waste of concrete. On the other hand, one cylinder body 1 is saved, which is easy to carry. In addition, the first cover body 3 and the second cover body 6 are detachably connected to the cylinder body 1, which is convenient for disassembly and cleaning.

[0029] As Figure 2 shown, in one embodiment, the hopper 2 includes two side plates 202 arranged oppositely, and a transverse plate 203 connecting the two side plates 202. The two side plates 202 are sealed at the bottom by an arc-shaped plate 204. One end of the arc-shaped plate 204 is connected to the bottom of the transverse plate 203, and the other end is connected to the top of the side plate 202, for enclosing and forming the sampling bin 201. Specifically, in order to facilitate the collection of concrete, in this embodiment, the hopper 2 is defined as being composed of two side plates 202, a transverse plate 203 and an arc-shaped plate 204. The two side plates 202 are arranged oppositely and have a first end face and a second end face arranged oppositely. The first end faces of the two are hermetically connected by the transverse plate 203, and the second end faces of the two are hermetically connected by the arc-shaped plate 204, and the arc-shaped plate 204 extends after bending to be hermetically connected to the lower end of the transverse plate 203, so as to form the sampling bin 201, so as to facilitate the quantitative excavation of concrete. In addition, the setting of the arc-shaped plate 204 can reduce the adhesion of concrete, and the hopper 2 can be tilted during sampling. Preferably, a plurality of saw teeth 205 are provided at one end of the arc-shaped plate 204 facing away from the transverse plate 203. Preferably, the transverse plate 203 is fixed to the first cover body 3, and a notch is provided thereon for communicating the sampling bin 201 and the discharge port 4.

[0030] As Figure 3 shown, in one embodiment, the second cover body 6 is provided with a driving component for driving a plurality of the stirring blades 5 to rotate synchronously. The driving component includes a driving gear 7 and a plurality of driven gears 8. The driving gear 7 is rotatably arranged on the second cover body 6, and the plurality of driven gears 8 are meshed with the driving gear 7 and are respectively connected to a plurality of the stirring blades 5. Specifically, in order to drive a plurality of stirring blades 5 to rotate synchronously, in this embodiment, a driving gear 7 and a plurality of driven gears 8 are arranged on the second cover body 6. The driving gear 7 is driven by a motor to rotate at the second cover body 6, and the plurality of driven gears 8 are meshed with the driving gear 7 for transmitting power to each stirring blade 5 to make it rotate. AsFigure 1 , Figure 3 As shown in Figure 3 , in this embodiment, in order to facilitate the display of each part of the driving component, the housing structure for protecting the driving component is omitted here.

[0031] As Figure 1 shown, in one embodiment, the stirring blade 5 includes a rotating shaft 501 connecting the driven gear 8, and a plurality of stirring parts 502 arranged at intervals around the rotating shaft 501. The stirring parts 502 are of a spiral structure, and both ends thereof extend towards both ends of the rotating shaft 501 respectively. Specifically, in order to improve the stirring uniformity of the concrete in the cylinder 1, in this embodiment, by defining that the stirring blade 5 includes a rotating shaft 501 and a plurality of stirring parts 502, the rotating shaft 501 is used to connect to the corresponding driven gear 8, and the plurality of stirring parts 502 are arranged around the axis of the rotating shaft 501 at intervals to improve the stirring force of the stirring blade 5. Further, the above-mentioned stirring parts 502 are of a spiral type, and both ends thereof are respectively fixed at both ends of the rotating shaft 501, so that the middle part of the entire stirring blade 5 is in an outward-expanded state, improving the stirring force. At the same time, the hollow stirring blade 5 is also convenient for flushing and reduces the cleaning dead angle.

[0032] As Figure 3 shown, in one embodiment, the second cover 6 is provided with a water injection port 9 for injecting a fixed amount of water into the cylinder 1 when stirring the concrete to prevent it from hardening. Of course, the water injection port 9 can be sealed by a sealing cover to prevent the concrete from popping out from the water injection port 9.

[0033] In one embodiment, the inner surfaces of the first cover 3 and the second cover 6 have a first thread structure, and the outer surface of the cylinder 1 has a second thread structure. The two thread structures cooperate so that the corresponding cover can be detachably covered on the cylinder 1 to achieve the purpose of quick installation and quick disassembly.
