[0001] The utility model relates to the technical field of conveying equipment, in particular to a conveying mechanism capable of adjusting the conveying speed. Background Art

[0002] Ball mill steel balls are the medium for grinding materials in ball mill equipment, and the grinding effect is produced by the collision and friction between the steel balls and the materials.

[0003] Steel balls can be produced by rolling with a rotary forging machine: the round steel bar is heated in a heating furnace and then rolled into a ball through three main processes: cutting, forming and rounding. Generally, one steel ball is produced for each rotation of the roller. This method has high production efficiency and the surface quality of the steel balls produced is guaranteed.

[0004] The steel balls processed by the rotary cutting and rolling forging machine are transported to the starting end of the conveyor through the conveyor mechanism, and then transported upward to the quenching equipment by the conveyor. Figure 1 As shown, it includes a support frame 1, on which a guide groove body 2 is arranged. The guide groove body 2 is inclined, and the upper end of the guide groove body 2 is close to the discharge port of the rotary cutting and rolling forging machine, and the lower end of the guide groove body 2 is close to the starting end of the conveyor. When the steel ball rolls on the guide groove body 2, it rolls from the upper end of the guide groove body 2 to the lower end of the guide groove body 2.

[0005] Affected by the load performance of the conveyor, the capacity of the quenching equipment and the production rhythm, it is necessary to adjust the transmission speed of the steel balls on the transmission mechanism in order to adjust the number of steel balls transmitted on the conveyor and the amount of steel balls transmitted by the conveyor to the quenching equipment, so as to adapt to the load performance of the conveyor, the capacity of the quenching equipment and the production rhythm.

[0006] However, the current conveying mechanism cannot adjust the conveying speed of the steel balls, which reduces the flexibility of use.

[0007] Therefore, how to adjust the conveying speed of the steel balls on the conveying mechanism in order to improve the flexibility of use is a technical problem that needs to be solved at present. Utility Model Content

[0008] In view of the above-mentioned deficiencies in the prior art, the utility model provides a conveying mechanism with adjustable conveying speed. The utility model can adjust the conveying speed of the steel balls on the conveying mechanism, thereby improving the use flexibility.

[0012] Furthermore, the mounting frame includes two mounting plates, the guide groove body is arranged between the two mounting plates, the avoidance groove is arranged at the upper ends of the two mounting plates, the elastic member is arranged on the side where the two mounting plates are close to each other, and the turntable is arranged on the side where the two mounting plates are far away from each other.

[0013] Furthermore, the mounting plate is detachably connected to the guide slot body.

[0014] Furthermore, a handle is provided at one end of the slide rod.

[0015] Furthermore, a dovetail long groove is provided on the adjusting rod, the long side direction of the dovetail long groove is parallel to the axial direction of the adjusting rod, and the dovetail long groove is slidably matched with the adjusting block.

[0016] The utility model has the beneficial effects:

[0017] 1. In the present invention, the height of the adjusting rod can be adjusted by adjusting the height of the height adjustment component, changing the angle between the first connecting rod and the second connecting rod, changing the spacing between two adjacent sliding sleeves, changing the spacing between two adjacent chains, and adjusting the density of the chain, thereby changing the contact area between the chain and the steel ball. When the contact area between the steel ball and the chain is smaller, it means that the steel ball is less blocked by the chain, which can increase the transmission speed of the steel ball, thereby adjusting the transmission speed of the steel ball on the transmission mechanism, and improving the flexibility of use.

It is worth noting that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0045] Example:

[0046] like Figure 2-Figure 9 As shown, a conveying mechanism with adjustable conveying speed includes a support frame 1, a guide slot body 2 is welded and fixed on the support frame 1, and the guide slot body 2 is inclined.

[0047] A mounting frame is provided at the upper end of the guide slot body 2. The mounting frame includes two mounting plates 4, and the guide slot body 2 is provided between the two mounting plates 4.

[0048] The mounting plate 4 is detachably connected to the guide slot body 2. For example, the mounting plate 4 can be fixed to the guide slot body 2 using screws, and after the screws are removed, the mounting plate 4 and the guide slot body 2 can be separated.

[0049] The two mounting plates 4 are rotatably connected to the same slide bar 5. A handle 5-1 is welded and fixed to one end of the slide bar 5. A worker can drive the slide bar 5 to rotate relative to the mounting plate 4 by rotating the handle 5-1.

[0050] A plurality of sliding sleeves 6 are sleeved on the sliding rod 5. In this embodiment, five sliding sleeves 6 are provided, and the five sliding sleeves 6 are all arranged between the two mounting plates 4. The sliding sleeve 6 can slide along the axial direction of the sliding rod 5. When the sliding rod 5 is rotated, the sliding rod 5 can also rotate in the inner cavity of the sliding sleeve 6. The chains 3 are welded and fixed on the five sliding sleeves 6.

[0051] Among two adjacent sliding sleeves 6 , one sliding sleeve 6 is rotatably connected to the lower end of the first connecting rod 7 , and the other sliding sleeve 6 is rotatably connected to the lower end of the second connecting rod 8 . The upper ends of the first connecting rod 7 and the second connecting rod 8 are rotatably connected to the same adjustment block 9 .

[0052] The five sliding sleeves 6 need to be used in conjunction with four adjusting blocks 9, and the four adjusting blocks 9 are slidably connected to the same adjusting rod 10 along the axial direction of the adjusting rod 10. For details, see Fig. 9 A dovetail long groove 10-1 is provided on the adjusting rod 10, and the long side direction of the dovetail long groove 10-1 is parallel to the axial direction of the adjusting rod 10, see Figure 8 The dovetail long groove 10-1 is slidably matched with the adjusting block 9. The adjusting rod 10 is arranged parallel to the sliding rod 5.

[0053] A height adjustment component is provided on the mounting frame, and the height adjustment component is used to adjust the height of the adjustment rod 10.

[0054] The height adjustment assembly includes a rotating disk 11 and an elastic member 12 .

[0055] A rotating disk 11 is welded and fixed at both ends of the slide bar 5, and the two mounting plates 4 are arranged between the two rotating disks 11. The arrangement of the two rotating disks 11 can prevent the slide bar 5 from moving axially relative to the mounting plate 4, so that the slide bar 5 can only rotate relative to the mounting plate 4, preventing the slide bar 5 from axially moving when rotating, and improving the reliability of the slide bar 5 when rotating.

[0056] The turntable 11 is provided with a plurality of adjustment slots of different depths. Figure 7 There are four adjustment grooves on the turntable 11, which are respectively marked as the first adjustment groove 11-1, the second adjustment groove 11-2, the third adjustment groove 11-3, and the fourth adjustment groove 11-4. The depth of the first adjustment groove 11-1 is greater than the depth of the second adjustment groove 11-2, the depth of the third adjustment groove 11-3, and the depth of the fourth adjustment groove 11-4.

[0057] The upper ends of the two mounting plates 4 are provided with avoidance grooves 4-1. The depth of the avoidance grooves 4-1 is greater than the depth of the largest adjustment groove. In this embodiment, the depth of the avoidance grooves 4-1 is greater than the depth of the first adjustment groove 11-1. When the adjustment rod 10 enters the adjustment grooves of different depths, it will not be hindered by the avoidance grooves 4-1.

[0058] The elastic member 12 can be a spring. The two mounting plates 4 are both provided with an elastic member 12 on the side close to each other, one end of the elastic member 12 is welded and fixed to the mounting plate 4, and the other end of the elastic member 12 is welded and fixed to the slide bar 5, and the elastic member 12 is used to pull the adjustment rod 10 downward.

[0059] The conveying mechanism of this embodiment with adjustable conveying speed needs to be placed between the rotary cutting and rolling forging machine and the conveyor when in use, and the upper end of the guide groove body 2 needs to be placed at the discharge port of the rotary cutting and rolling forging machine, and the lower end of the guide groove body 2 needs to be placed at the starting end of the conveyor. The red-hot steel ball 13 processed by the rotary cutting and rolling forging machine directly enters the guide groove body 2, and the steel ball 13 entering the guide groove body 2 rolls downward along the inclined direction of the guide groove body 2 into the conveyor under the action of inertia, and then is transported to the quenching equipment by the conveyor.

[0060] When the steel ball 13 enters the guide groove 2, it will be blocked by the chain 3. Figure 4 The larger the contact area between the steel ball 13 and the chain 3, the greater the resistance of the steel ball 13 by the chain 3, which can reduce the transmission speed of the steel ball 13; see Figure 5 The smaller the contact area between the steel ball 13 and the chain 3 is, the smaller the resistance of the steel ball 13 by the chain 3 is, and the transmission speed of the steel ball 13 can be increased.

[0061] In this embodiment, the density of the chains 3 can be adjusted by adjusting the distance between two adjacent chains 3, thereby adjusting the contact area between the chains 3 and the steel balls 13. Figure 4 The smaller the distance between adjacent chains 3 and the denser the chains 3 are, the greater the contact area between the chains 3 and the steel balls 13 will be; see Figure 5 The larger the distance between adjacent chains 3 is, the looser the chains 3 are, which will reduce the contact area between the chains 3 and the steel balls 13.

[0062] When adjusting the distance between two adjacent chains 3, the height of the adjusting rod 10 can be adjusted by the height adjustment component. The higher the height of the adjusting rod 10, the larger the distance between the adjusting rod 10 and the sliding rod 5, the smaller the angle between the first connecting rod 7 and the second connecting rod 8, the smaller the distance between two adjacent sliding sleeves 6, and the smaller the distance between two adjacent chains 3.

[0063] For example, in this embodiment, because the depth of the first adjustment groove 11-1 is greater than the depth of the second adjustment groove 11-2 and the depth of the third adjustment groove 11-3 and the depth of the fourth adjustment groove 11-4, when the end of the adjusting rod 10 is located in the avoidance groove 4-1 and the first adjustment groove 11-1, the height of the adjusting rod 10 is the lowest, and the distance between the adjusting rod 10 and the slide bar 5 is the smallest, and the angle between the first connecting rod 7 and the second connecting rod 8 is the largest, the distance between two adjacent sliding sleeves 6 is the largest, and the distance between two adjacent chains 3 is the largest; when the end of the adjusting rod 10 is located in the avoidance groove 4-1 and the fourth adjustment groove 11-4, the height of the adjusting rod 10 is the highest, and the distance between the adjusting rod 10 and the slide bar 5 is the largest, and the angle between the first connecting rod 7 and the second connecting rod 8 is the smallest, the distance between two adjacent sliding sleeves 6 is the smallest, and the distance between two adjacent chains 3 is the smallest.

[0064] When using the height adjustment assembly to adjust the height of the adjustment rod 10, the worker first needs to overcome the elastic force of the elastic member 12 to lift the adjustment rod 10; then the worker rotates the slide bar 5, and the slide bar 5 drives the turntable 11 to rotate, so that the adjustment groove of the appropriate depth is rotated to a position connected with the avoidance groove 4-1; then the worker puts the adjustment rod 10 into the avoidance groove 4-1 and the current adjustment groove, and the elastic force of the elastic member 12 pulls the adjustment rod 10 to prevent the adjustment rod 10 from escaping from the avoidance groove 4-1 and the adjustment groove upward, and the groove wall of the avoidance groove 4-1 can prevent the turntable 11 and the slide bar 5 from rotating, so as to stabilize the current height of the adjustment rod 10 and complete the adjustment of the height of the adjustment rod 10.

[0065] In addition, during the process of adjusting the height of the adjusting rod 10, the angle between the first connecting rod 7 and the second connecting rod 8 changes. Since the adjusting block 9 can slide along the axial direction of the adjusting rod 10, and the sliding sleeve 6 mounted on the sliding rod 5 can slide along the axial direction of the sliding rod 5, the adjusting block 9 and the sliding sleeve 6 can slide to adapt to the height change of the adjusting rod 10.

[0066] It can be seen from the above description that in the transmission mechanism of the present embodiment with adjustable transmission speed, the height of the adjusting rod 10 can be adjusted by adjusting the height of the height adjustment component, the angle between the first connecting rod 7 and the second connecting rod 8 can be changed, the spacing between two adjacent sliding sleeves 6 can be changed, the spacing between two adjacent chains 3 can be changed, and the density of the chains 3 can be adjusted, thereby changing the contact area between the chains 3 and the steel balls 13. When the contact area between the steel balls 13 and the chains 3 is smaller, it means that the steel balls 13 are blocked less by the chains 3, and the transmission speed of the steel balls 13 can be increased, thereby achieving the adjustment of the transmission speed of the steel balls 13 and improving the flexibility of use.

[0067] The conveying mechanism with adjustable conveying speed in this embodiment is a purely mechanical structure and is stable and reliable in use.

[0068] The height adjustment component of the present embodiment has a simple structure, which can further simplify the overall structure of the conveying mechanism with adjustable conveying speed of the present embodiment, making it easier to assemble and maintain, and more stable and reliable to use.

[0069] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
