DETAILED DESCRIPTION
[0028] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0029] Embodiment 1:

[0031] A soil foundation concrete preparation device comprises a mobile support 10 and a preparation tank 20 fixed in the mobile support 10.
[0032] By providing a mobile bracket, the preparation tank can be driven to move within a short distance, so that the position of the prepared concrete can be adjusted at any time at the construction site.
[0033] A feeding box 30 is also provided above the preparation tank 20, and a mixing assembly is provided on one side of the feeding box 30. The mixing assembly includes a power mechanism 40 provided on one side of the feeding box 30 and a mixing mechanism cooperating with the power mechanism 40. The mixing mechanism is located in the preparation tank 20 and can be extended and retracted outward with the power mechanism 40 as the center axis.
[0034] The mixing mechanism includes an axis component 50 fixedly connected to the output end at the bottom of the power mechanism 40, and an equal number of telescopic pillars 501 are distributed in a ring at the top and bottom of the axis component 50, and a scraper 502 is fixedly provided between two telescopic pillars 501 located on the same horizontal base surface, and a plurality of groups of stirring paddles 503 are equidistantly provided on the inner side of the scraper 502 from top to bottom.
[0035] The mixing mechanism also includes a telescopic driving component arranged in the top end of the shaft component 50, and the telescopic driving component includes a rotating motor 504 fixedly arranged in the shaft component 50, and the output end of the rotating motor 504 is fixedly sleeved with a first bevel gear 505, and a screw 506 is rotatably provided at a fixed end position in the telescopic support 501 at the top of the shaft component 50, and a second bevel gear 507 meshing with the first bevel gear 505 is fixedly sleeved at one end of the screw 506 close to the shaft component 50, and a driving member 508 fixedly connected to the telescopic end of the telescopic support 501 is also threadedly sleeved on the outer periphery of the screw 506.
[0036] By driving the shaft component 50 through the power mechanism 40, the scraper 502 and the stirring paddle 503 can be driven to rotate, so that the soil-based concrete raw materials in the preparation tank 20 can be stirred and mixed. In the process of rotation, the rotating motor 504 can be used to drive the screw 506 to rotate, thereby driving the telescopic support 501 to move, so that the scraper 502 and the stirring paddle 503 are telescoped outward with the shaft component 50 as the center axis, so that the stirring range can be adjusted, or the stirring range can be kept in a changing state at all times, which can avoid the occurrence of stirring dead corners, so that the sand and gravel raw materials in the preparation tank 20 can be fully mixed together, which can improve the overall concrete preparation effect.
[0037] The scraper 502 is arranged parallel to the inner wall of the preparation tank 20, and the telescopic support 501 can make the scraper 502 collide with the inner wall of the preparation tank 20 when it is in the longest extension state.
[0038] After the preparation is completed, by making the telescopic support 501 in the longest extended state, the scraper 502 can come into contact with the inner wall of the preparation tank 20, and then rotate it to scrape off the concrete adhering to the inner wall of the preparation tank 20 and discharge it through the outlet at the bottom, which can not only reduce the waste of concrete, but also prevent the concrete adhering to the inner wall of the preparation tank 20 from becoming solid and difficult to clean after a period of time.

[0043] The power mechanism 40 is a double-axle asynchronous motor, which is one of the existing motors. The output end of the motor has a faster rotation speed than the output end of the top, so that the material discharge time will not be as fast as the stirring speed.

A feed baffle 603 is fixedly provided at the bottom of the drive shaft 60 and is in contact with the bottom of the annular feed trough 301. The cross-sectional area of the feed baffle 603 is larger than the cross-sectional area of the feed hole 302, and the number of the feed baffles 603 is the same as the number of the feed holes 302.
[0045] By providing a feeding box 30 above the preparation tank 20, concrete admixtures or other small amounts of raw materials can be placed in the feeding box 30. As the power mechanism works, the driving shaft 60 in the feeding box 30 can be driven to rotate at the same time, and the diameter of the second pulley 601 is made larger than the diameter of the first pulley 401. The shaft component 50 can be rotated for multiple circles before the driving shaft 60 rotates one circle. When the driving shaft 60 rotates, the bottom discharge baffle 603 can be driven to rotate. When the discharge baffle 603 does not overlap with the discharge hole 302, the concrete admixtures or raw materials in the feeding box 30 can fall into the preparation tank 20. In the process of preparing soil-based concrete, concrete admixtures or supplementary raw materials can be added in small amounts multiple times, which can improve the mixing effect.
[0046] The driving shaft 60 is also fixed with a plurality of groups of anti-blocking scrapers 602 that contact the inner wall of the annular material discharge chute 301 , and the anti-blocking scrapers 602 are distributed in an annular shape with the driving shaft 60 as the central axis.
[0047] By fixing an anti-blocking scraper 602 on the outer periphery of the driving shaft 60 , the concrete admixture or raw material in the feeding box 30 can be scraped into the annular feeding trough 301 as the driving shaft 60 rotates, which facilitates feeding and prevents the feeding hole 302 from being blocked.
