Description

Technical Field

[0001] This utility model belongs to the field of unloading machine technology, specifically relating to a defrosting device for unloading machines. Background Technology

[0002] Existing long-distance transportation mostly uses railway transportation, which has a large single transport capacity and low cost. In the transportation of bulk materials (such as coal), in order to reduce environmental pollution during transportation, it is usually necessary to spray water to suppress dust. However, in cold environments, a frozen layer often forms on the edge of the carriage wall. While unloading machines can unload at high speed, frozen material cannot be unloaded effectively, thus affecting the unloading process and making it impossible to complete effective clearing.

[0003] Chinese patent CN113003247A discloses a negative pressure unloading machine using a material collector, which can transport materials over long distances and complete the unloading process. However, it cannot be used for unloading in situations with frozen layers.

[0004] Therefore, how to provide a defreezing device for unloading machines that can effectively break through the frozen layer to complete the unloading is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a defreezing device for unloading machines, which can remove the frozen layer without affecting unloading, thereby improving the applicability of the equipment.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a defreezing device for an unloading machine, comprising:

[0007] The lifting slide is used to connect to the unloading machine gantry. A vertical screw feeding mechanism is connected to the lifting slide, and the bottom of the vertical screw feeding mechanism is provided with a feeding port.

[0008] A feeding mechanism is installed at the bottom end of the lifting slide, and the feeding mechanism gathers the material and introduces it into the feed inlet;

[0009] The freezing head is located on one side of the lifting slide. Multiple telescopic control arms are hinged to the top two sides of the freezing head. The other ends of the multiple telescopic control arms are respectively hinged to the lifting slide and / or the feeding mechanism. The multiple telescopic control arms cooperate to control the lifting and tilting of the freezing head.

[0010] The beneficial effects of this utility model are: this device has both unloading and defreezing functions. It uses a defreezing head to break the frozen layer inside the truck bed. The defreezing head is controlled by multiple telescopic control arms, which can change the working position of the defreezing head. The defreezing head will not affect the normal unloading work when it is raised. After the defreezing head is lowered by the telescopic control arms, the frozen layer on the bottom and side walls of the truck bed is broken. At the same time, the broken material is pushed to the feeding mechanism. It is convenient to use and thus improves the practicality of the equipment.

[0011] Preferably, the feeding mechanism includes a collection tray, a transmission assembly, and a collection tray drive motor. The collection tray is rotatably connected to the bottom end of the lifting slide and is located at the feed inlet. The outer side wall of the collection tray is provided with drive teeth. The transmission assembly meshes with the drive teeth for transmission. A bracket for mounting the collection tray drive motor is fixed on the lifting slide. The bracket is located at the middle of the axial direction of the lifting slide.

[0012] The resulting technical effect is that the collection tray can gather materials together and introduce them into the feed inlet, and the subsequent vertical screw feeding mechanism completes the subsequent material transfer and unloading process. The collection tray is driven to rotate by a drive motor and transmission components.

[0013] Preferably, there are two telescopic control arms, one of which is hinged at the top of the lifting slide, and the other is hinged at the top of the seat frame. The bottom of the telescopic control arms is hinged to the two sides of the thawing head, and the top hinge points of the two telescopic control arms have a height difference.

[0014] The resulting technical effect is that the telescopic control arm not only supports the thawing head, but also changes the working position of the thawing head. The height misalignment of the top hinge point of the telescopic control arm is intended to deflect the thawing head and complete the thawing operation on the compartment wall.

[0015] Preferably, the telescopic control arm is a hydraulic telescopic arm.

[0016] The resulting technical advantages are: hydraulic drive has a large torque, is easy to control, has stable drive, is reliable in operation, and is suitable for harsh working environments.

[0017] Preferably, the freezing head includes a drive box, a roller rotating frame, and a freezing roller. The top of the drive box is provided with a lug for connecting a telescopic control arm. The roller rotating frame is fixed to the bottom of the drive box. The freezing roller is rotatably connected to the roller rotating frame. A hydraulic drive motor is provided inside the drive box. The output shaft of the hydraulic drive motor is connected to the freezing roller in a transmission manner.

[0018] The resulting technical effect is that the thawing roller can break up frozen materials on the bottom or side walls of the carriage over a large area in a flat plane. It is fast, efficient, and the hydraulic drive can provide a large rotational torque to meet the torque requirements of the thawing operation.

[0019] Preferably, the outer wall of the thawing roller is provided with a plurality of cutting teeth, which are arranged in a spiral pattern.

[0020] The resulting technical effect is that the spiral-shaped cutting teeth can improve the freezing efficiency and break through the hard frozen layer. Attached Figure Description
