Technical Field
[0001] The present application relates to the technical field of sand making equipment, and specifically discloses a feed regulating device for a sand making machine. Background Art
[0002] Sand making machine is a machine used to crush hard ore materials. It is widely used in artificial sand making. There are mainly vertical shaft sand making machine and horizontal sand making machine. The rotor axle of the horizontal sand making machine is set horizontally, and the entire equipment occupies a small area, so it is widely used.
[0003] The feed port of an existing sand making machine is usually located at the top of the machine, and ore materials are fed into the sand making machine through the feed port, and the ore materials are crushed by the crushing mechanism equipped in the sand making machine. However, during feeding, since the ore materials are fed from the feed port and fall directly into the crushing mechanism inside the sand making machine through free fall, the ore materials before crushing fall directly onto the crushing mechanism. If this continues for a long time, it is easy to damage the crushing mechanism and other structures inside the sand making machine, affecting the normal crushing of the ore materials, and easily causing the sand making machine to malfunction, resulting in equipment damage and increasing the workload of equipment maintenance, affecting the service life of the sand making machine and the operation of production work. Therefore, in view of this, the inventor provides a feed adjustment device for a sand making machine to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to solve the problem that when a traditional sand making machine is being fed, the ore material is easily dropped directly onto the crushing mechanism of the sand making machine during free fall motion, which can easily cause the sand making machine to be smashed and malfunction, thus affecting the production operation of the sand making machine.
[0005] In order to achieve the above-mentioned purpose, the basic scheme of the present invention provides a feed adjustment device for a sand making machine, comprising a feed port provided at the top of the sand making machine and a feed piece installed at the feed port, the feed port comprising a first inclined slot provided at the top of the sand making machine and inclined downward, and a second inclined slot connected to the bottom of the first inclined slot and inclined downward, the inclination directions of the first inclined slot and the second inclined slot are opposite, the crushing mechanism is located at the bottom end of the second inclined slot, the feed piece comprises a first feed roller group rotatably connected to the inner wall of the sand making machine and located above the bottom inclined surface of the first inclined slot, and a second feed roller group rotatably connected to the inner wall of the sand making machine and located on the bottom inclined surface of the second inclined slot, both the first feed roller group and the second feed roller group can be used to support and convey ore materials, and an adjustment mechanism for adjusting the inclination angle of the second feed roller group is also installed on the outside of the sand making machine.
[0006] The principles and effects of this basic solution are:
[0007] 1. Compared with the prior art, the present invention sets the feed port of the sand making machine as a broken line connecting structure of the first inclined slot and the second inclined slot, so that the ore material is decelerated after passing through two slopes and a direction turn before being crushed, avoiding direct free fall and hitting the crushing mechanism, which not only better protects the structure of the sand making machine, but also reduces the feeding speed, avoids blockage at the crushing mechanism, and makes the structure run more stably. At the same time, by setting the first feed roller group and the second feed roller group, it is convenient to support the ore material to roll along the first inclined slot and the second inclined slot to the crushing mechanism, making feeding more convenient, and solving the problem that when feeding the traditional sand making machine, the ore material is easily dropped directly onto the crushing mechanism of the sand making machine during free fall, which easily causes the sand making machine to be hit and malfunction, affecting the production and operation of the sand making machine.
[0008] 2. Compared with the prior art, the present invention adjusts the inclination direction of the second feed roller group by setting an adjustment mechanism, thereby adjusting the opening width of the second chute near the bottom outlet of the crushing mechanism, which is convenient for adjusting the feed amount and controlling the particle size of the fed ore material.
[0009] Furthermore, the first feed roller assembly includes a plurality of first support rollers, each of which is rotatably connected to the inner walls of the sand making machine at both ends and is linearly arranged along the bottom side of the first chute opening. Adjacent first support rollers are tangentially connected to each other, and each first support roller is also tangentially connected to the bottom side of the first chute opening. The first support rollers are arranged on the first chute opening to facilitate receiving ore materials that fall on the bottom side of the first chute opening and redirecting the ore materials toward the second chute opening in the inclined direction of the first chute opening. The tangential connections between the first support rollers and between the first support rollers and the first chute opening prevent the ore materials from falling into the gap between the first support rollers and the bottom side of the first chute opening, thereby affecting the normal rotation of the first support rollers.
[0010] Furthermore, the second feed roller group includes a head-end support roller, a tail-end support roller, and a plurality of second support rollers disposed between the head-end support roller and the tail-end support roller. Joint plates parallel to the inclination direction of the second inclined notch are symmetrically mounted on the inner walls of both sides of the sand making machine. The ends of the head-end support roller, the ends of the tail-end support roller, and the ends of the second support roller are rotatably connected between the inner sides of the joint plates, and the outer sides of the joint plates are in contact with the inner walls of the sand making machine. The provision of the joint plates facilitates the installation and fixation of the second feed roller group, allowing the head-end support roller, the tail-end support roller, the second support roller, and the joint plates to form an integral structure, thereby improving the stability of the structure and making it more compact.
[0011] Furthermore, the outer side of one end of the combined plate is provided with a mounting shaft coaxially arranged with the head end support roller, and the mounting shaft is rotatably connected to the side wall of the sand making machine. The adjusting mechanism includes an adjusting link symmetrically located on the outer side of both ends of the sand making machine and coaxially connected to the mounting shaft and the tail end support roller at both ends, an arc-shaped through groove symmetrically arranged on the side walls of both ends of the sand making machine, and a sliding column which is located between the outer side of the combined plate and the inner side of the adjusting link and coaxially arranged with the tail end support roller and can slide in the arc-shaped through groove. The end at which the sliding column is connected to the adjusting link is provided with a material baffle symmetrically located on the outer side of the sand making machine and used to prevent ore materials from leaking out of the arc-shaped through groove. It also includes an electric telescopic rod hinged between the middle part of the outer side of any adjusting link and the outer side of one end of the sand making machine and a controller for electrically controlling the electric telescopic rod. By setting the mounting shaft and the sliding column, the combined plate is connected and installed with the adjusting link, and the rotation of the combined plate and the entire second feed roller group and the adjusting link around the mounting shaft and the head end support roller is realized at the same time. By setting the telescopic adjustment of the electric telescopic rod, the adjusting link is driven to swing around the mounting shaft, thereby driving the overall structure of the combined plate connected and installed with the adjusting link and the second feed roller group to swing and adjust synchronously, thereby achieving the purpose of adjusting the width of the bottom end outlet of the second inclined slot.
[0012] Furthermore, the retaining plate is an arc-shaped structure proportional to the shape of the arc-shaped slot, with the ratio of the retaining plate to the arc-shaped slot being 2.5. By defining the retaining plate's shape, the retaining plate can completely block and seal the arc-shaped slot when the adjustment link rotates to any angle. This allows for adjustment of the tail end support roller angle while preventing leakage of ore materials. The structure is simple and easy to use.
[0013] Furthermore, an articulated seat is provided on the outer side of one end of the sand making machine and is located above the arc-shaped through groove, and an end of the electric telescopic rod away from the adjusting connecting rod is hinged to the articulated seat. By arranging the articulated seat, the installation and use of the electric telescopic rod are facilitated. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0020] A feed regulating device for a sand making machine, for example Figure 1 and Figure 2 As shown: it includes a feed port provided at the top of the sand making machine 1 and a feed part installed at the feed port, the feed port includes a first inclined slot 2 provided at the top of the sand making machine 1 and inclined downward, and a second inclined slot 3 connected to the bottom of the first inclined slot 2 and inclined downward, the inclination directions of the first inclined slot 2 and the second inclined slot 3 are opposite, wherein the first inclined slot 2 is inclined to the lower left, and the second inclined slot 3 is inclined to the lower right, and the crushing mechanism 14 is located at the bottom end of the second inclined slot 3, the feed part includes a first feed roller group rotatably connected to the inner wall of the sand making machine 1 and located above the bottom inclined surface of the first inclined slot 2 and a second feed roller group rotatably connected to the inner wall of the sand making machine 1 and located on the bottom inclined surface of the second inclined slot 3, both the first feed roller group and the second feed roller group can be used to support and convey ore materials, and an adjustment mechanism for adjusting the inclination angle of the second feed roller group is also installed on the outside of the sand making machine 1.
[0021] Among them, such as Figure 1 and Figure 2 As shown, the first feed roller group includes more than ten first support rollers 4 whose ends are rotatably connected to the inner walls of both sides of the sand making machine 1 and are linearly arranged along the bottom side of the first inclined slot 2. Two adjacent first support rollers 4 are tangentially connected, and the first support rollers 4 are also tangentially connected to the bottom side of the first inclined slot 2.
[0022] Among them, such as Figure 1 and Figure 2As shown, the second feed roller group includes a head end support roller 5, a tail end support roller 6 and more than ten second support rollers 7 arranged between the head end support roller 5 and the tail end support roller 6. Two joint plates 8 parallel to the inclination direction of the second inclined slot 3 are symmetrically installed on the inner walls of both sides of the sand making machine 1. The two ends of the head end support roller 5, the two ends of the tail end support roller 6 and the two ends of the second support roller 7 are respectively rotatably connected between the inner sides of the joint plates 8, and the outer side surfaces of the joint plates 8 are fitted and connected to the inner wall of the sand making machine 1.
[0023] Among them, such as Figure 1 and Figure 2 As shown, the outer side of the left end of each joint plate 8 is provided with a mounting shaft 15 which is coaxially arranged with the head end support roller 5, and the mounting shaft 15 is rotatably connected to the side wall of the sand making machine 1, as shown in FIG. Figure 3 As shown, the adjustment mechanism includes an adjustment link 9 symmetrically located on the outside of the front and rear ends of the sand making machine 1 and coaxially connected to the mounting shaft 15 and the tail end support roller 6 at the left and right ends respectively, an arcuate through groove 10 symmetrically arranged on the side walls of the front and rear ends of the sand making machine 1, and a sliding column that can slide in the arcuate through groove 10 and is arranged between the outer side of the joint plate 8 and the inner side of the adjustment link 9 and coaxially arranged on the tail end support roller 6. The end of the sliding column connected to the adjustment link 9 is provided with a baffle plate 11 symmetrically located on the outside of the sand making machine 1 and used to prevent the ore material from leaking out from the arcuate through groove 10. It also includes an electric telescopic rod 12 hinged between the outer middle part of the outer side of the adjustment link 9 located on the outer side surface of the front end of the sand making machine 1 and the outer side surface of the front end of the sand making machine 1, and a controller for electrically controlling the electric telescopic rod 12, and the controller includes but is not limited to a PLC controller.
[0024] Among them, such as Figure 1 and Figure 3 As shown, the baffle plate 11 is an arc-shaped structure that is proportional to the shape of the arc-shaped through groove 10. The shape ratio of the baffle plate 11 to the arc-shaped through groove 10 is 2.5. The structural centers of the baffle plate 11 and the arc-shaped through groove 10 are both the axis of the mounting shaft 15.
[0025] Among them, a hinge seat 13 located above the arc-shaped through groove 10 is provided on the outer side of the front end of the sand making machine 1, and the end of the electric telescopic rod 12 away from the adjusting connecting rod 9 is hinged to the hinge seat 13.
[0026] In the specific implementation process of the present invention, the blanking width of the bottom port of the second inclined slot 3 is first adjusted according to the actual working conditions. When the tail end support roller 6 is located at the lowest end of the arc-shaped through slot 10, the blanking width of the bottom port of the second inclined slot 3 is the largest. When the tail end support roller 6 is located at the highest end of the arc-shaped through slot 10, the blanking width of the bottom port of the second inclined slot 3 is the smallest. When adjusting the blanking width of the bottom port of the second inclined slot 3, the controller controls the electric telescopic rod 12 to extend, thereby driving the adjusting connecting rod 9, the joint plate 8 and the second feed roller group to rotate clockwise, and the sliding column slides downward along the arc-shaped through slot 10, thereby increasing the blanking width of the bottom port of the second inclined slot 3. Conversely, when the electric telescopic rod 12 contracts, the blanking width of the bottom port of the second inclined slot 3 is adjusted to be smaller.
[0027] After the required discharge width of the bottom port of the second chute 3 is adjusted according to the actual working conditions, the crushing mechanism 14 is started, and the ore material that needs to be sand-made is fed into the first chute 2. After entering the first chute 2, the ore material falls on the first support roller 4, and rolls toward the lower left along the inclination direction of the first feed roller group and then falls on the second support roller 7, and then rolls toward the lower right along the inclination direction of the second feed roller group and then falls on the crushing mechanism 14 located at the bottom port of the second chute 3. After the ore material is crushed by the crushing mechanism 14, it falls to the bottom of the sand making machine 1 below the crushing mechanism 14 for aggregation. After the sand making is completed, the obtained ore sand is collected and output.
[0028] Compared with the prior art, the present invention sets the feed port of the sand making machine 1 as a broken line connecting structure of the first inclined slot 2 and the second inclined slot 3, so that the ore material can be decelerated after passing through two slopes and a direction turning before being crushed, avoiding direct free fall and hitting the crushing mechanism 14, which can not only better protect the structure of the sand making machine 1, but also reduce the feeding speed, avoid blockage at the crushing mechanism 14, and make the structure run more stably. At the same time, by providing the first feeding roller group and the second feeding roller group, it is convenient to support the ore material to roll along the first inclined slot 2 and the second inclined slot 3 to the crushing mechanism 14, making feeding more convenient, and solving the problem that in the traditional sand making machine 1, when feeding, the ore material is easily dropped directly onto the crushing mechanism 14 of the sand making machine 1 during free fall motion, which easily causes the sand making machine 1 to be hit and malfunction, thereby affecting the production operation of the sand making machine 1;
[0029] By setting the electric telescopic rod 12 and the adjusting connecting rod 9, the inclination direction of the second feed roller group is adjusted, thereby adjusting the opening width of the bottom outlet of the second inclined slot 3 close to the crushing mechanism 14, which facilitates the adjustment of the feed amount and the control of the particle size of the fed ore material.
[0030] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention.
