It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0021] Example 1

[0022] like Figure 1-3 As shown, the utility model is a foam lightweight soil batching mechanism for roadbed construction, including a vertically arranged shell body 1, the shell body 1 is funnel-shaped, a discharge pipe is arranged at the lower part of the shell body 1, the discharge pipe is provided with a solenoid valve, a spiral 3 extends into the discharge pipe, a main shaft 2 is vertically arranged in the shell body 1, and a power mechanism is connected to the upper end, a spiral 3 is vertically fixedly sleeved on the outer wall of the main shaft 2, a matching cylinder 4 is vertically sleeved outside the spiral 3, the lower end of the matching cylinder 4 is fixedly connected to the inner wall of the shell body 1 through a connecting rod, the upper and lower ends of the spiral 3 extend to the outside of the matching cylinder 4 respectively, a stirring mechanism is connected to the outer side wall of the upper part of the main shaft 2, the stirring mechanism includes an L-shaped stirring rod 10 fixedly installed on the upper part of the outer side wall of the main shaft 2, a plurality of twigs are horizontally fixedly installed on the outer side wall of the stirring rod 10, a feed hopper 5 is fixedly connected to the upper end surface of the shell body 1, and a Crushing roller 6, which can crush the ingredients and assist in feeding. The crushing roller 6 is connected to a driving mechanism, which includes a second motor 11 fixedly installed horizontally on the upper end face of the shell 1. The shafts of the two crushing rollers 6 at the same end respectively penetrate the feed hopper 5. The shafts of the two crushing rollers 6 are located outside the feed hopper 5 and are fixedly sleeved with gears 12. The two gears 12 are meshed and connected. The output shaft of the second motor 11 is fixedly connected to the shaft of one of the crushing rollers 6. A transport device 7 fixedly connected to the feed hopper 5 is obliquely arranged above the feed hopper 5. Baffles 8 are fixedly installed at equal intervals on the crawler surface of the transport device 7. The device can prevent the ingredients from sliding downward through the transport device 7 with the baffles 8 to ensure the stability of the ingredients in transportation. At the same time, a screw 3 is arranged to cooperate with a matching cylinder 4 to optimize the batching effect.

[0023] Example 2

[0024] like Figure 1-3As shown, the power mechanism includes a first motor 9 vertically fixedly installed on the upper end surface of the shell 1. The output shaft of the first motor 9 rotates and passes through the upper wall of the shell 1 and is fixedly connected to the main shaft. The first motor 9 of the power mechanism adopts a servo motor that can rotate forward and reversely. The forward rotation of the first motor 9 can drive the screw 3 to rotate forward. The cooperation of the matching cylinder 4 can transport the lower ingredients in the shell 1 upward from the inside of the matching cylinder 4, while the ingredients outside the matching cylinder 4 move downward, so as to realize the upper and lower circulation mixing of the ingredients. The reverse rotation of the first motor 9 can drive the screw 3 to rotate reversely, drive the ingredients to move downward, promote discharge, and avoid blockage.

[0025] Working principle:

[0026] When in use, the control starts the transport device 7, the second motor 11 and the first motor 9, and controls the first motor 9 to rotate forward. The second motor 11 drives the gear 12 directly connected thereto and the crushing roller 6 to rotate, and indirectly drives another crushing roller 6 to rotate synchronously through the transmission of the gear 12. The first motor 9 indirectly drives the screw 3 and the stirring rod 10 to rotate forward through the transmission of the main shaft 2, and pours the ingredients onto the crawler of the transport device 7. The crawler sends the ingredients upward into the feed hopper 5, which is crushed by the crushing roller 6 and then enters the shell 1 for mixing and stirring. At the same time, the screw 3 continuously transports the ingredients at the bottom of the shell 1 from the matching cylinder 4 upward to achieve circular mixing. After mixing, the solenoid valve can be opened and the first motor 9 can be controlled to rotate in the opposite direction, driving the screw 3 to rotate in the opposite direction to send the ingredients out.
