The tilt angle is 40-75°. The upper part is equipped with a limiting structure (to block and limit the feeding car 2 at the high position, by blocking the feeding car 2 or the pulley 9, etc.).

[0021] The feeding trolley 2 is slidably mounted on the gantry frame 1, with open bottom and top. Located on the rear side (specifically, the adjacent rear side) of the gantry frame 1, it is a vertically arranged rectangular bucket, positioned along the front-to-back direction (the left and right sides are also positioned along the front-to-back direction). Its bottom is a conical structure (larger at the top and smaller at the bottom), and it has two pulleys 9 on each of its left and right sides. Specifically, a support 11 (specifically an angular structure) is located on the front side of the conical structure. The two pulleys 9 are respectively located at both ends of the first rotating shaft, which is coaxial with the first rotating shaft, which is positioned along the left-to-right direction and mounted on the support 11. The vertical beam of the gantry frame 1 opens inward (to the left or right) to form a groove 3 (slanted forward and upward) that cooperates with the pulleys 9. The pulleys 9 slide within the groove 3 on the corresponding side.

[0022] The lifting structure is used to drive the feeding vehicle 2 to slide upward along the chute 3, and it is specifically located between the top beam and the support 11.

[0023] The U-shaped plate 8 is fixed to the bottom of the feeding vehicle 2, located between two vertical beams. It is open to the front, and its top is fixed to the lower part of the conical structure. It includes a left arm (located along the front-rear direction, on the left side of the conical structure), a right arm (located along the front-rear direction, on the right side of the conical structure), and a rear arm (located along the left-right direction, on the rear side of the conical structure, between the rear ends of the left and right arms). The left and right arms are fixed to the left and right sides of the conical structure, respectively, and the rear arm is fixed to the rear side of the conical structure. Two sliding wheels 10 are provided at the bottom front end of each of the left and right arms of the U-shaped plate 8.

The two sliding wheels 10 are slidably positioned on the rear side of the two vertical beams.

[0024] The discharge chute 4 is hinged to the bottom of the feeding cart 2 and is arranged in the front-rear direction. Its front end extends forward relative to the bottom of the feeding cart 2 (preferably also extending forward relative to the U-shaped plate 8). Its front side is open, and its rear end is hinged to the front side of the rear arm of the U-shaped plate 8 (via a left-right rotating shaft). There are two discharge pulleys 5 on the left and right sides of its front part, which close the bottom of the feeding cart 2 and can be flipped downwards. It is located between the left and right arms of the U-shaped plate 8, and its left and right groove edges are located on the left and right sides of the bottom of the feeding cart 2, with the distance between them gradually decreasing from top to bottom.

Its rear end is connected to the front side of the chute 3 to form a Y-shaped groove. The front part of the discharge pulley 5 can be embedded into the rear ends of the left and right frame sides of the fixed frame 6.

[0026] The top of the cone hopper 7 is fixed to the fixed frame 6. It is located directly above the feed inlet of the mixing device (which is small, so it is necessary to set up the cone hopper 7). It is set in the front and back direction. Its top is rectangular. It has a structure that is larger at the top and smaller at the bottom. It is located in front of the feeding car 2 and adjacent to the front of the gantry frame 1. Specifically, it is a rectangular cone hopper.

[0027] Among them, two support frames 12 are used to support the fixed frame 6, which are located on the left and right sides of the fixed frame 6 between the fixed frame 6 and the ground, and are vertically arranged.

The front part of the discharge pulley 5 is embedded in the rear end of the left and right frame sides of the fixed frame 6. The discharge chute 4 is flipped downward and is set obliquely downward from back to front (the inclination angle is less than 15°). The gap between the front side of the bottom of the feeding cart 2 and the discharge chute 4 forms the discharge port. The front end of the discharge chute 4 is located adjacent to the rear upper part of the cone hopper 7. The material (flowing out from the bottom of the feeding cart 2) flows into the cone hopper 7 along the discharge chute 4.

[0031] In this embodiment of the present invention, the sliding pulley 10, the pulley 9, and the discharge pulley 5 are all single-sided T-shaped track wheels.

[0032] Example 2 See Figure 1-2 Example 2 provides a non-powered automatic material feeding lifting device, whose structure is basically the same as that of Example 1, except that the lifting feeding device in this example also includes a ground trough 15 that can accommodate the feeding cart 2. The ground trough 15 is specifically a rectangular trough arranged in the front-to-back direction. The lower part of the gantry frame 1 is located in the ground trough 15.

Both the support 11 and the top beam of the gantry frame 1 are equipped with wire rope pulleys. The wire rope of the lifting structure passes over the wire rope pulleys on the support 11. Specifically, a fixed pulley is provided at the middle and one end (left or right end) of the top beam, and a movable pulley is provided at the middle of the support 11. One end of the wire rope is fixed to the middle of the top beam, goes downwards and passes over the movable pulley, goes upwards and passes over the fixed pulley in the middle, runs left and right and passes over the fixed pulley at the end, and then goes downwards (along the outside of a vertical beam, where corresponding wire rope pulleys can be provided for guidance) to the corresponding winch.

[0034] Example 4 See Figure 3Example 4 provides a non-powered automatic feeding and lifting device, whose structure is basically the same as that of Example 1, except that: in this example, a rear crossbeam 13 is provided between the left and right arms of the U-shaped plate 8, and a front crossbeam 14 is provided on the lower side of the fixing frame 6.
