Description

Technical Field

[0001] The utility model relates to the technical field of road machinery and equipment, in particular to a high modulus agent feeding machine. Background Art

[0002] High modulus agent is a black granular solid. It is very easy to use. When the asphalt mixture is heated to 170-180 degrees, the high modulus agent can be directly added into the mixing. Adding high modulus agent to asphalt mixed aggregate can improve the high temperature stability of asphalt mixed aggregate and effectively prevent the formation of road rutting.

[0003] For example, a device for feeding anti-rutting agent disclosed in the patent authorization announcement number CN 209812849 U, referring to Figure 1 As shown, a hose is connected to the discharge pipe of the device, and the high modulus agent is delivered to the asphalt mixing bin through the hose.

[0004] This hose structure is suitable for delivering granular materials on the ground to a mixing bin at a higher position, and its use cost is low. However, the weight of the high modulus agent delivered to the mixing bin needs to be controlled according to the requirements. When the weight of the high modulus agent delivered to the mixing bin meets the requirements, the delivery needs to be stopped immediately. At this time, the material still being delivered in the hose will fall down due to the stop. The material will accumulate at the lower end of the hose, which may make it difficult to start the hose the next time it absorbs the material. In addition, the material falling down will also collide with the hose, affecting the stability of the hose. Summary of the invention

[0005] In view of the problems pointed out in the background technology, the utility model proposes a high modulus agent feeding machine to solve the above technical problems.

[0006] The technical solution of the utility model is achieved in this way:

[0007] A high modulus agent feeding machine, comprising a storage bin,

[0008] It also includes a transfer bin, a hose spiral feeding device, a screw feeding device, and a recovery pipe;

[0009] The transfer bin is arranged above the storage bin, and an openable and closable recovery port is arranged at the bottom of the transfer bin, one end of the recovery pipe is connected to the recovery port, and the other end of the recovery pipe extends into the storage bin;

[0010] The hose spiral feeding device can deliver the materials in the storage bin into the transfer bin;

[0011] The screw feeding device can deliver the materials in the transfer bin into the asphalt mixing bin.

[0012] The utility model is further configured that the hose spiral feeding device comprises a fixed tube, a hose, a conveying shaft, a spiral coil, and a motor;

[0013] The fixed tube is fixedly arranged on the transfer bin, and is provided with a discharge port facing the transfer bin. A rotatable conveying shaft is arranged inside one end of the fixed tube, and the motor is used to drive the conveying shaft to rotate. One end of the hose is connected to the other end of the fixed tube, and the other end of the hose extends into the storage bin. The spiral coil is arranged in the hose, and one end of the spiral coil is fixedly connected to the conveying shaft, and the conveying shaft can drive the spiral coil to rotate.

[0014] The utility model is further configured that the screw feeding device comprises a straight pipe, a screw, and a motor;

[0015] The straight pipe is arranged obliquely, the lower end of the straight pipe extends into the bottom of the transfer bin, and a second discharge port is arranged on the side wall of the upper end of the straight pipe;

[0016] The screw is rotatably arranged inside the straight pipe, and the second motor is used to drive the screw to rotate.

[0017] The utility model is further configured such that a baffle of a pull-out structure is provided at the recovery port.

[0018] By adopting the above technical solution, when the materials in the transfer bin need to be cleaned, the baffle can be pulled outward to open the recovery port, and the materials in the transfer bin enter the recovery pipe through the recovery port and then fall into the storage bin.

[0019] The utility model is further configured that a feeding port is provided on the material storage bin, and a rotatable cutting knife is provided at the feeding port.

[0020] By adopting the above technical solution, the bagged materials can be directly put into the feeding port, the cutting knife cuts the bag, and the materials in the bag flow out and enter the discharge bin.

[0021] The utility model is further configured that a carrier plate which can be elastically moved up and down is provided at the feeding port, a slot corresponding to the cutting knife is provided on the carrier plate, and when the carrier plate moves to the upper position, the cutting knife is located at the lower side of the carrier plate.

[0022] The utility model is further configured that a spring is provided on the lower side of the carrier plate, the upper end of the spring is fixedly connected to the carrier plate, and the lower end of the spring is fixedly connected to the wall of the feeding port.

[0023] The utility model is further configured that the carrier plate is provided with a plurality of through holes.

[0024] The utility model is further configured that the edge of the carrier plate is spaced apart from the wall of the feeding port.

[0025] By adopting the above technical solution, the carrier plate can play the role of carrying the bag. Normally, the carrier plate rises to the upper side of the cutting knife. When the bag is placed on the carrier plate, the carrier plate moves downward under the action of the gravity of the bag, and the bag contacts the cutting knife and is cut open. As the material in the bag falls out into the storage bin, the carrier plate gradually rises.

[0026] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0027] The high modulus agent feeder provided by the utility model uses a combination of a hose spiral feeding device and a screw feeding device to add high modulus agent to an asphalt mixing bin at a higher position. The hose spiral feeding device is first used to feed the material on the ground to the transfer bin (the hose spiral feeding device has a simple structure and is easy to set up. The installation environment basically does not affect the installation of the hose spiral feeding device, which is convenient for feeding the material into the transfer bin at a higher position). Then, the material in the transfer bin is fed into the asphalt mixing bin through the screw feeding device (when the screw feeding device is started or stopped, the transported material will also start or stop accordingly, which is convenient for controlling the transported material).
