Description

Technical Field

[0001] The utility model belongs to the technical field of concrete production equipment, and in particular relates to concrete preparation and production equipment. Background Art

[0002] Recycled concrete refers to the waste concrete blocks that have been crushed, cleaned, and graded, mixed with grading in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel, and then adding cement, water, etc. to stir to generate new concrete. Recycled concrete has been widely used in daily life and production. When the existing mixing device stirs recycled concrete, the mixing shaft always rotates in one direction to stir the concrete in the device, resulting in low mixing efficiency, long mixing time, and uneven mixing. Therefore, it is necessary to design a concrete preparation and production equipment. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1-4 As shown, a concrete preparation and production equipment comprises a base 1 and a mixing barrel 2, the mixing barrel 2 is installed on the upper side of the base 1, the mixing barrel 2 is funnel-shaped as a whole, a feed inlet is opened on the upper side of the mixing barrel 2, a feed hopper 3 is connected to the upper side of the feed inlet, and a vertical mixing device is installed inside the mixing barrel 2;

[0020] The vertical stirring equipment includes a conveying pipe 4, which is vertically installed on the inner side of the stirring barrel 2. A connecting bracket 5 fixedly connected to the inner wall of the stirring barrel 2 is installed on the outer side of the conveying pipe 4. An auger 6 matching the conveying pipe 4 and rotatably connected to the stirring barrel 2 is installed on the inner side of the conveying pipe 4. A motor 7 is installed on the lower side of the base 1. The output end of the motor 7 is transmission-connected to the auger 6, and a horizontal stirring assembly is installed on the side of the auger 6.

[0021] When the utility model is in use, processed concrete raw materials, sand, cement, water, etc. are added from the feed hopper 3 to the inner side of the mixing barrel 2, and then the motor 7 is driven to rotate the auger 6, and the auger 6 continuously transports the concrete raw materials inside the mixing barrel 2 to the upper side of the conveying pipe 4, and flows from the outer side of the conveying pipe 4 to the bottom of the mixing barrel 2, realizing up and down tumbling, and the horizontal stirring component can stir the concrete raw materials horizontally.

[0022] The cooperation between the conveying pipe 4 and the auger 6 allows the concrete to be rolled up and down inside the mixing barrel 2 for mixing, so that the concrete can be mixed both horizontally and vertically inside the mixing barrel 2, thereby improving the mixing efficiency, shortening the concrete mixing time, and making the concrete mixing more uniform to improve the quality of concrete production.

[0023] The horizontal stirring assembly includes a stirring rod 8, which is fixedly connected to one side of the auger 6. A support rod 9 is also fixedly installed on the upper side of the auger 6. A transmission rod 10 rotatably connected to the support rod is vertically installed at one end of the support rod 9. A stirring plate 11 is fixed to the lower side of the transmission rod 10. A gear 12 is concentrically fixed to the upper side of the transmission rod 10. A gear ring 13 matching the gear 12 is fixedly installed on the upper inner wall of the stirring barrel 2, and the gear ring 13 and the gear 12 are meshed with each other.

[0024] The stirring rod 8 can stir the concrete inside the mixing barrel 2 in the horizontal direction when the auger 6 rotates. When the auger 6 rotates, the support rod 9 drives the transmission rod 10 and the stirring plate 11 to revolve around the auger 6. The cooperation between the gear 12 and the ring gear 13 enables the stirring plate 11 to rotate simultaneously when revolving around the outer side of the conveying pipe 4, and the superimposed stirring effect ensures that the concrete is evenly mixed in a local horizontal range, thereby controlling the flow, heat exchange and uniform mixing of the concrete.

[0025] A scraper 14 is installed on the side of the auger 6 . The scraper 14 and the connecting bracket 5 do not interfere with each other. The scraper 14 abuts against the inner wall of the mixing barrel 2 and is transmission-connected to the auger 6 .

[0026] The scraper 14 can rotate along with the auger 6 when it rotates, and can prevent the concrete inside the mixing barrel 2 from sticking to the inner wall of the mixing barrel 2 when the mixing equipment is working, thereby improving the mixing efficiency. At the same time, the scraper 14 can scrape off the concrete stuck to the inside of the mixing barrel 2, making it convenient for the staff to clean the mixing barrel 2 and reducing the staff's workload.

[0027] A discharge port 15 is provided at the lower side of the mixing barrel 2, and a discharge baffle 17 is installed on the outer side of the discharge port 15 for sliding up and down. A control rod 18 is hinged on the side of the base 1, and a pull rod 19 is hinged on one end of the control rod 18, and the other end of the pull rod 19 is transmission connected to the discharge baffle 17. A discharge hopper 16 is installed at the lower side of the discharge port 15, which is lower than the discharge port 15 and tilted downward on the outer side.

[0028] When the mixing of the concrete inside the mixing barrel 2 is completed, only one end of the control rod 18 needs to be pressed downward, and the other end of the control rod 18 can drive the pull rod 19 upward to lift the discharge baffle 17 upward, and the concrete can flow out of the discharge hopper 16. The staff only needs to move one end of the control rod 18 upward, and the other end of the control rod 18 can drive the pull rod 19 downward to lower the discharge baffle 17, and the concrete inside the mixing barrel 2 stops being discharged.

[0029] The discharge damper 17 with upper and lower switches has high flexibility in controlling concrete discharge and is convenient for adjusting the concrete flow rate. The discharge hopper 16 below the discharge port 15 can effectively prevent the discharge damper 17 from being closed when the discharge port 15 is blocked by concrete, thereby improving the reliability of the equipment.

[0030] An observation window is provided on the side of the mixing barrel 2, and an inspection door 20 is hingedly connected to the outer side of the observation window.

[0031] When the utility model works normally, the inspection door 20 is in a closed state, and the inspection door 20 can be opened to facilitate cleaning or inspection of the inside of the mixing barrel 2, thereby improving the convenience of using the equipment.

[0032] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
