DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 , Figure 2 , Figure 3 The utility model provides a technical solution: a distributor for a roasted sand storage tank, comprising a distributor base 1 and a distributor device 2.

[0022] A rotating groove 14 is provided on the top surface of the distributor base 1, and the distributor device 2 is rotatably connected to the rotating groove 14 of the distributor base 1. The distributor base 1 is provided with a motor 11, and a gear ring 23 is fixedly sleeved on the outer side surface of the distributor device 2. The driving end of the motor 11 is meshed with the gear ring 23 through a gear.

[0023] The bottom surface of the material distributor 2 is provided with a material feeding protrusion 25 , and the bottom surface of the distributor base 1 is provided with a material discharge trough 13 for connecting the material feeding protrusion 25 , and a flip cover 12 is provided at the material discharge trough 13 .

[0024] The flip cover 12 is provided at the bottom surface of the distributor base 1 and the material discharge chute 13, and one end of the flip cover 12 is hinged to the side wall of the material discharge chute 13. When the material feeding protrusion 25 descends and inserts into the material discharge chute 13, the material feeding protrusion 25 pushes the flip cover 12 downward, and when the material feeding protrusion 25 rises upward, the flip cover 12 returns to its position and buckles to prevent the material from being spilled.

[0025] The flip cover 12 needs to be able to bear a large weight, because the feeding protrusion 25 is always connected to the feeding trough 24, and the feeding trough 24 is always sleeved on the outer wall of the feeding pipe 28, so when the feeding protrusion 25 is in the feeding state, the rotating block 22 rotates, and the material will flow into the rotating trough 14 of the distributor base 1. When there is material on the top surface of the flip cover 12, the flip cover 12 is not affected, until the feeding protrusion 25 is inserted into the corresponding feeding trough 13, the material on the top surface of the flip cover 12 will also flow into the pipeline.

[0026] It should be noted here that if Figure 2 As shown, a mounting groove is also provided at the connection position between the top of the feed chute 13 and the bottom surface of the distributor base 1, and the mounting groove is used to install the flip cover 12 so that the connection of the flip cover 12 is flush with the bottom surface of the distributor base 1 to avoid protrusion causing the feed protrusion 25 to get stuck when rotating.

[0027] Furthermore, the material dividing device 2 includes an upper box body 21 and a rotating block 22. A hydraulic cylinder 27 is provided in the upper box body 21. The driving end of the hydraulic cylinder 27 passes through the bottom surface of the upper box body 21 and is fixedly connected to the top surface of the rotating block 22. The bottom surface of the rotating block 22 is provided with the feeding protrusion 25. The top surface of the rotating block 22 is provided with a material passing groove 24, and the material passing groove 24 is connected to the bottom surface of the feeding protrusion 25.

[0028] Wherein, the rotating tank 14 is as follows Figure 1 As shown, a stepped design can be adopted. A portion of the rotating trough 14 close to the bottom surface is a lifting portion, the cross-sectional diameter of the lifting portion is consistent with the cross-sectional diameter of the rotating block 22, and the depth is equal to the thickness of the feed protrusion 25. A portion of the rotating trough 14 close to the top is a limiting portion, and the cross-sectional diameter of the limiting portion is slightly smaller than the cross-sectional diameter of the rotating block 22. This design can limit the lifting height of the rotating block 22, and avoid the feed protrusion 25 being unable to accurately align with the feed trough 13 due to a long path. Because the side wall of the rotating trough 14 of the distributor base 1 will inevitably have dirt due to long-term use, resulting in jamming or reduced movement accuracy, in this application, the lifting range of the rotating block 22 is limited by setting the depth of the lifting portion of the rotating trough 14 to be equal to the thickness of the feed protrusion 25, thereby avoiding the above-mentioned problems.

[0029] A material passing pipe 28 is disposed in the upper box body 21 , the top end of the material passing pipe 28 passes through the top surface of the upper box body 21 , and the bottom end of the material passing pipe 28 passes through the bottom surface of the upper box body 21 and is inserted into the material passing groove 24 .

[0030] The bottom end position of the feed pipe 28 is as follows Figure 1 As shown, it is necessary to keep the bottom end of the material passing pipe 28 in the material passing groove 24 at all times, so as to avoid material splashing on the one hand and bear part of the torque on the other hand.

[0031] Furthermore, the bottom surface of the upper box body 21 is provided with a plurality of positioning rods, and the top surface of the rotating block 22 is provided with a plurality of limiting grooves for inserting the positioning rods. The driving end of the hydraulic cylinder 27 cannot withstand excessive torque, so a plurality of positioning rods are evenly arranged along the circumferential direction on the bottom surface of the upper box body 21, and the plurality of positioning rods simultaneously share the torque, which can protect the normal operation of the hydraulic cylinder 27 to a great extent.

[0032] Furthermore, the bottom surface of the rotating block 22 is provided with a plurality of positioning protrusions 26 for inserting into the feeding trough 13. The positioning protrusions 26 are completely consistent in shape and size with the feeding protrusions 25, and the positioning protrusions 26 and the feeding protrusions 25 are evenly arranged along the circumferential direction on the bottom surface of the rotating block 22, and the number and arrangement positions of the feeding trough 13 are also consistent with the positions of the positioning protrusions 26 and the feeding protrusions 25. The positioning protrusions 26 can scrape off a portion of the material remaining on the bottom surface of the rotating trough 14 of the distributor base 1, and can also allow the rotating block 22 to maintain horizontal rotation.

[0033] Furthermore, the top of the feed pipe 28 is connected to a rotary joint 3 through a pipeline. A rotary joint refers to a pipe connection device, and the connected pipes can rotate relatively, which can be used to transmit various media such as gas, liquid, oil, etc., with a compact design structure and a flange connection. The top of the rotary joint 3 is connected to a main silo, and the main silo connects the material to the structure of the present application through the rotary joint 3 for material distribution.

[0034] Furthermore, the upper box body 21 includes a rotating box 211 and an upper box cover 212, and the upper box cover 212 is detachably connected to the top surface of the rotating box 211. Because the upper box body 21 is provided with multiple components, the upper box body 21 adopts a split design so that the staff can flexibly disassemble and assemble the internal components.

[0035] Working principle:

[0036] First, turn on the motor 11 to rotate the feed protrusion 25 to the top of one of the discharge troughs 13, then turn on the hydraulic cylinder 27 to insert the feed protrusion 25 into the discharge trough 13, and the feed protrusion 25 pushes the flip cover 12 downward to open the discharge valve of the main silo, and the material enters the feed pipe 28 through the rotary joint 3.

[0037] At this time, the corresponding material discharge chute 13 needs to be replaced, and the hydraulic cylinder 27 is turned on to lift the material feeding protrusion 25. After the rotating block 22 rises to the top, the motor 11 is turned on to control the upper box 21 to drive the rotating block 22 to rotate, so that the material feeding protrusion 25 is transferred to the next material discharge chute 13.
