[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0022] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0023] See also Figure 1 , which shows a structural schematic diagram of an embodiment of the ball-making disk scooping device of the utility model, comprising: a base rod 1, which is arranged near the ball-making disk; an electric telescopic structure 2, one end of which is fixed to the top end of the base rod, and the other end is a telescopic end, and points to the inside of the ball-making disk; a ball-scooping structure 3, one end of which is movably connected to the bottom end of the base rod, and the other end is movably connected to the telescopic end of the electric telescopic structure; wherein, the base rod 1, the electric telescopic structure 2 and the ball-scooping structure 3 form a triangular structure, and the electric telescopic structure serves as the hypotenuse of the triangle. When the length of the electric telescopic structure changes, it will drive the ball-scooping structure to move up and down.

[0024] In a further embodiment, in order to facilitate the catching of large balls in different positions, the device of this embodiment also includes: a horizontal steering mechanism (wrapped inside the locking structure and therefore not shown), the horizontal steering mechanism is a bearing structure, the outer ring of the bearing is fixedly connected to the ground or a fixed bracket, and the inner ring of the bearing is fixedly connected to the base rod, which is used to drive the base rod to rotate horizontally, so that the electric telescopic structure and the ball catching structure fixed to the base rod can pivot horizontally with the base rod.

[0025] In a further embodiment, in order to cooperate with the horizontal steering mechanism, the device of this embodiment also includes: a locking structure 4, which is divided into two parts, and is in the shape of a flange. The upper and lower flanges are fixedly connected to the outer ring of the bearing and the base rod respectively, and locking holes are arranged on the disk surface of the upper and lower flanges.

[0026] For details, see Figure 2The locking structure 4 is composed of two upper and lower flanges. The upper flange 4-1 is fixedly connected to the base rod and can rotate with the base rod. The lower flange 4-2 is fixedly connected to the outer ring of the bearing of the horizontal steering mechanism and cannot rotate. The upper and lower flanges are provided with locking holes of the same size, number and corresponding positions. When the locking members are used to pass through the locking holes on the upper and lower flange surfaces in sequence to connect the upper and lower flanges together, the lower flange cannot rotate, thereby limiting the relative rotation of the upper flange, and further limiting the position and angle of the ball scooping structure relative to the ball making disk; for example: the ball scooping mechanism and the rotation tangent direction of the ball making disk are at an acute angle (0°~90°), so that the large balls at different positions in the ball making disk are guided by the ball scooping structure and roll off the ball making disk.

[0027] In a further embodiment, in order to cooperate with the locking structure, the device of this embodiment also includes: a locking member, which is L-shaped or T-shaped and is used to pass through the locking hole on the lower upper flange to lock the rotation angle of the horizontal steering structure.

[0028] For details, please refer to Figure 3 and Figure 4 The locking piece must not only be able to pass through the locking holes in sequence, but also needs to maintain the locking state of the upper and lower flanges. Therefore, one end of the locking piece needs to have an L-shaped head or a T-shaped head for clamping on the upper flange surface.

[0029] In a further embodiment, the electric telescopic structure includes: a hydraulic pump 2-1 and a hydraulic rod 2-2; wherein the hydraulic pump 2-1 is airtightly connected to the hydraulic rod 2-2 to control the extension and retraction of the hydraulic rod 2-2 to change the length of the electric telescopic structure.

[0030] In further embodiments, see Figure 5 The electric telescopic structure also includes: a dust cover 5, which is elastic and is sleeved on the outside of the hydraulic rod to isolate dust.

[0031] In a further embodiment, in order to cooperate with the hydraulic pump, the device of the utility model also includes: a telescopic switch 6, which is electrically connected to the hydraulic pump and is used to control the working state of the hydraulic pump, wherein the working state includes pumping hydraulic oil into the hydraulic rod and pumping hydraulic oil out of the hydraulic rod.

[0032] For details, see Figure 5 The telescopic switch is in the shape of a circular ring. When it is rotated clockwise, it controls the hydraulic pump to pump hydraulic oil out of the hydraulic rod to control the hydraulic rod to retract. When it is rotated counterclockwise, it controls the hydraulic pump to pump hydraulic oil into the hydraulic rod to control the hydraulic rod to extend.

[0033] In a further embodiment, the ball scooping structure includes: a rake head 3-1 and a rake rod 3-2; wherein the rake head 3-1 is fixedly connected to one end of the rake rod 3-2, and the other end of the rake rod 3-2 is movably connected to the bottom end of the base rod 1. The rake teeth spacing of the rake head is 5-10mm; and the length of the rake head is 30-100cm.

[0034] In an optional embodiment, in order to smoothly guide the large balls to roll, the spacing between the rake teeth gradually decreases from one side of the rake head to the other side. More specifically, the spacing between the rake teeth close to the center of the ball-making disk is larger than the spacing between the rake teeth close to the edge of the ball-making disk. It can be understood that the smaller the spacing between the rake teeth, the smaller the rolling resistance for guiding the raw balls to roll, and the easier it is to guide the large balls to roll.

[0035] In one application scenario, the use of the large ball scooping device of the pelletizing disk of the utility model includes: a worker stands near the pelletizing disk and controls the rotation of the ball scooping device, and controls the extension and retraction of the hydraulic rod to adapt to the height of the slag, thereby scooping large balls at different positions on the pelletizing disk.

[0036] In another application scenario, the use of the ball-making disk large ball scooping device of the utility model includes: manually locking the locking structure through a locking piece so that the ball scooping structure forms a certain angle with the rotation direction of the ball-making disk, thereby scooping the large balls in the fixed position.

[0037] The utility model can effectively avoid the accumulation of large balls in the ball making disk, can adapt to the height of the slag in the ball making disk to scoop up large balls at different positions, and is provided with a locking structure to fix the ball scooping position, which is convenient for off-shift work.
