DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following further describes the present utility model with reference to the drawings:

[0030] A gob filling device proposed in this embodiment, as Figure 1As shown, the top of the outer wall of the hopper 6 is fixedly connected to the support 1. Inside the hopper 6, there are stirring rods and augers. The motor at the top of the hopper 6 can drive the stirring rods and augers to rotate. At the bottom of the hopper 6, there is a feeding pipe that can extend to the mined - out area of the iron ore to be filled in cooperation with the external pipeline. The stirring rods mix the fillers inside the hopper 6 and convey them to the mined - out area of the iron ore through the augers. At the same time, the external mortar is mixed with the fillers by a grouting pump and conveyed to the mined - out area of the iron ore for filling. At the end of the hopper 6, there is a feeding pipe 7. The bottom of the feeding pipe 7 is rotatably connected to the elbow 8. The elbow 8 can rotate along the feeding pipe 7 and can be connected to the external connecting pipes at different directions and angles.

[0031] As Figure 1 and Figure 2 shown, multiple support rods 2 are provided at the bottom end of the support 1. The support rods 2 are annularly distributed around the support 1 at equal angles. The bottom end of the support rod 2 is rotatably connected to the screw rod 4. The bottom of the screw rod 4 is threadedly connected to the base 5. When the screw rod 4 rotates, the screw rod 4 can rotate along the support rod 2 and move along the thread groove of the base 5, so as to adjust the height of a single group of support rods 2. An auxiliary structure 3 is provided in the middle of the screw rod 4. Personnel can rotate the screw rod 4 through the auxiliary structure 3 to adjust the height of a single group of support rods 2, which increases the torque for personnel to rotate the screw rod 4 and makes it easier to adjust the height of a single group of support rods 2.

[0032] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, the auxiliary structure 3 is composed of a connection component 301, a support component 302, a drive component 303 and a turning handle 304;

[0033] The connection component 301 is connected to the screw rod 4. A support component 302 is arranged on the outside of the connection component 301. A drive component 303 is arranged in the middle of the support component 302. A turning handle 304 is arranged on the outside of the right side of the support component 302.

[0034] As Figure 3 、 Figure 4 and Figure 5 shown, the connection component 301 includes a sleeve 3012 and a round block 3011. The sleeve 3012 is fixedly connected to the screw rod 4. The middle of the outer wall of the sleeve 3012 is fixedly connected to the round block 3011. When the round block 3011 rotates, it can drive the screw rod 4 to rotate through the sleeve 3012. A plurality of connection grooves 3013 are processed annularly at equal angles on the outside of the round block 3011 for connecting with the drive component 303;

[0035] The support component 302 includes a support base 3022 and a cylinder 3021. One side of the outer ring surface of the cylinder 3021 is fixedly connected to the support base 3022. Both sides of the cylinder 3021 are rotatably connected to the sleeve 3012. The support base 3022 can drive the cylinder 3021 to rotate along the sleeve 3012. The extended end of the support base 3022 is hinged to the handlebar 304. Both sides of the handlebar 304 are in interference fit with the support base 3022 and will not rotate along the hinge point of the support base 3022 without external force driving the handlebar 304. The handlebar 304 drives the cylinder 3021 to rotate through the support base 3022. A chute 3023 is machined at the top of the support base 3022;

[0036] The drive component 303 consists of a spring 3031, a slider 3032, a connecting block 3033, and a clamping block 3034. Both ends of the spring 3031 are fixedly connected to the connecting block 3033 and the inner wall of the support base 3022 respectively. The connecting block 3033 matches the inner cavity of the support base 3022, enabling the connecting block 3033 to slide in the inner cavity of the support base 3022. The upper end of the connecting block 3033 is fixedly connected to the slider 3032. The slider 3032 matches the chute 3023. The outer wall of the slider 3032 is relatively rough, increasing the friction force on the contact surface between the slider 3032 and the human hand, facilitating the person to drive the slider 3032. The slider 3032 can drive the connecting block 3033 to move, and the connecting block 3033 drives the spring 3031 to compress. The end of the connecting block 3033 is fixedly connected to the clamping block 3034. The connecting block 3033 can drive the clamping block 3034 to move. The clamping block 3034 has the same shape as the connecting groove 3013. The clamping block 3034 can match the connecting groove 3013 at the corresponding position of the round block 3011. When the clamping block 3034 separates from the connecting groove 3013 on the side adjacent to the clamping block 3034, the handlebar 304 drives the cylinder 3021 to rotate along the sleeve 3012. When the clamping block 3034 is connected to the connecting groove 3013 on the side adjacent to the clamping block 3034, the handlebar 304 drives the sleeve 3012 to rotate through the cylinder 3021.

[0037] Working principle:

[0038] When erecting the gob filling device, the operator rotates the handle 304 to make it parallel to the support base 3022. Then, the operator rotates the handle 304, and the handle 304 drives the cylinder 3021 to rotate through the support base 3022. Restricted by the clamping block 3034 and the connecting groove 3013, when the cylinder 3021 rotates, it drives the sleeve 3012 to rotate, and the sleeve 3012 drives the screw rod 4 to rotate. After the orientation of the handle 304 rotates to a certain direction, the operator can move the slider 3032. The slider 3032 drives the clamping block 3034 to disconnect from the connecting groove 3013 through the connecting block 3033. Subsequently, the handle 304 is pulled back to its initial position and the slider 3032 is released. The elastic force of the spring 3031 connects the clamping block 3034 with the corresponding connecting groove 3013. Continuing to pull the handle 304 to adjust the height of the support rod 2, affected by the weight of the device, the base 5 is closely attached to the ground, enabling the screw rod 4 to move along the thread groove of the base 5, thus realizing the adjustment of the height of a single set of support rods 2. In this way, the torque of the operator increases during the rotation of the screw rod 4, making it easier for the operator to adjust the height of a single set of support rods 2;

[0039] The mixing rod and the auger are driven to rotate by the motor at the top of the hopper 6. The filler inside the hopper 6 is transported to the iron ore gob through the feeding pipe in cooperation with the external pipeline. The mixing rod mixes the filler inside the hopper 6 and transports it to the iron ore gob through the auger. At the same time, the external mortar is mixed with the filler by the grouting pump and transported to the iron ore gob for filling.
