A rotating shaft is installed on the vehicle body at the middle position of the tractor body, a swing arm extending backward is rotatably installed on the rotating shaft, a mounting vertical plate is arranged at the end of the swing arm, and an electromagnetic chuck is installed on the mounting vertical plate.

[0006] Moreover, the tractor body is an autonomous navigation tractor body, and two driving wheels connected with a differential are arranged at the bottom of the autonomous navigation tractor body, and the rotating shaft is located directly above the middle position between the two driving wheels.

[0007] Moreover, the tail-suction mechanism further includes a deviation correction spring, deviation correction springs are symmetrically and obliquely pulled on both sides of the swing arm, and connecting rods are symmetrically arranged on the vehicle body of the tractor body, and the ends of each deviation correction spring are fixed on the connecting rods.

[0008] Moreover, the electromagnetic chucks are 1-4 arranged at intervals on the mounting vertical plate.

[0009] Moreover, the tail-suction mechanism further includes a metal proximity switch sensor, and a metal proximity switch sensor is arranged at the middle part of the mounting vertical plate.

[0010] Moreover, a protective cover is further included, and a protective cover placed above the rotating shaft and the deviation correction spring is arranged on the tractor body.

[0011] The advantages and beneficial effects of the utility model are:

[0012] 1. This tail-suction tractor realizes the automatic transfer of an autonomous navigation tractor by changing the existing form of manually connecting and disconnecting the tractor and the material truck to a form of connecting and disconnecting the material truck by an electromagnetic chuck. Since there is no need for manual operation, it saves labor and greatly improves the towing efficiency.

[0013] 2. This tail-suction tractor is designed with a deviation-correcting spring to ensure that the swing arm is always in the center position of the tractor, guaranteeing the smooth adsorption of the electromagnetic chuck to the material truck and the reliability of the material truck during towing movement.

[0014] 3. This tail-suction tractor is designed with a metal proximity switch sensor to detect the distance of the material truck to be adsorbed. When the preset distance is reached, the electromagnetic chuck is energized to achieve the adsorption of the material truck.

[0015] 4. The structure of this utility model is designed scientifically and reasonably, with the advantages of simple structure, labor-saving, improved towing efficiency, and easy implementation. It is a tail-suction tractor with high innovation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following further details the present utility model through specific embodiments. The following embodiments are only descriptive and not restrictive, and the protection scope of the present utility model cannot be limited thereby.

[0023] A tail-suction tractor, comprising a tractor body 3, the tractor body being an autonomous navigation tractor body. At the bottom of the autonomous navigation tractor body, there are two drive wheels 11 connected to a differential. The innovation lies in that: at the center position directly above the drive wheels of the tractor (the position between the centers of the two drive wheels), there is a tail-suction mechanism 1. The tail-suction mechanism includes a rotating shaft 8, a swing arm 6, a mounting vertical plate 5, and an electromagnetic chuck 4. At the middle position of the tractor body, a rotating shaft is installed on the vehicle body, which is directly above the middle position between the two drive wheels. A swing arm extending backward is rotatably installed on the rotating shaft. At the end of the swing arm, there is a mounting vertical plate, and an electromagnetic chuck is installed on the mounting vertical plate. In this embodiment, the electromagnetic chucks are 2 spaced apart on the mounting vertical plate.

[0024] In order to prevent the swing arm from shifting and affecting the adsorption of the electromagnetic chuck to the material vehicle, the tail-suction mechanism further includes a deviation-correcting spring 7. Deviation-correcting springs are symmetrically and obliquely pulled on both sides of the swing arm. Connecting rods 9 are symmetrically arranged on the vehicle body of the tractor body, and the ends of each deviation-correcting spring are fixed on the connecting rods. The setting of this deviation-correcting spring can keep the swing arm in the middle position all the time.

[0025] In order to avoid sundries falling in and affecting the work of the deviation-correcting spring and the rotating shaft, it further includes a protective cover 2. A protective cover covering the rotating shaft and the deviation-correcting spring is arranged on the tractor body.

[0026] The tail-suction mechanism further includes a metal proximity switch sensor 10. A metal proximity switch sensor is arranged in the middle of the mounting vertical plate, that is, between the two electromagnetic chucks.

[0027] During operation, the tractor retreats, and the metal proximity switch sensor detects the distance from the material vehicle. When the detected distance meets the set adsorption distance, the electromagnetic chuck is powered on to achieve the adsorption connection to the material vehicle; when the material vehicle is towed in place, the electromagnetic chuck is powered off to achieve the separation of the tractor and the material vehicle, thus realizing the purpose of automatically transporting the material vehicle by this tail-suction tractor and greatly improving the transportation efficiency.

[0028] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art can understand that: without departing from the spirit and scope of the present invention and the appended claims, various substitutions, changes, and modifications are possible. Therefore, the scope of the present invention is not limited to the content disclosed in the embodiments and drawings.
