Description

Technical Field

[0001] The utility model belongs to the field of rice conveyors, and particularly relates to a rice conveyor with adjustable conveying speed. Background Art

[0002] A rice conveyor is a device used to transport rice from one location to another. It typically consists of one or more conveyor belts, driven by an electric motor or other power source, to move rice along a predetermined path. Rice conveyors are primarily used in rice processing and packaging to improve production efficiency and automation. They can move rice between different workstations, such as from cleaning to grinding or from grinding to packaging. This reduces manual handling and labor intensity, improving production speed and quality.

[0003] Existing rice conveyors, when screening impurities, mostly use belt conveyors to transport rice. Although the belt conveyor can transport rice quickly and in large quantities, it still has certain practical defects in actual rice transportation. Specifically, the existing rice conveyor lacks a limiter on the top, which causes the rice to easily pile up too high during transportation. If the rice on the conveyor piles too high, it may cause the rice to overflow and scatter to the ground. At the same time, excessive rice accumulation may cause unstable conveying flow. When the rice piles too high, intermittent increases in rice flow may occur, resulting in uneven transportation. Therefore, to address the above problems, a rice conveyor with adjustable conveying speed is proposed. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example

[0024] Depend on Figure 1-4 Provided is a rice conveyor with adjustable conveying speed, comprising a conveyor frame 1;

[0025] Two panels 2 are mounted in parallel on the conveyor frame 1, and a belt conveyor wheel 3 is provided between the two panels 2;

[0026] Two collecting assemblies 4 are respectively provided on both sides of the belt conveyor wheel 3, and the two adjacent collecting assemblies 4 on the same side are arranged as a group;

[0027] The upper end surfaces of the two panels 2 are vertically assembled with a gantry 5, and the gantry 5 is assembled with a height limiting component 6;

[0028] The height limiting assembly 6 includes a positioning seat 61 arranged on the gantry 5, an adjusting plate 62 is installed on the side of the positioning seat 61, a threaded screw 65 is rotatably provided on the adjusting plate 62, and a slider seat 66 is slidably engaged on the outside of the threaded screw 65, a connecting block 67 is provided on the side of the slider seat 66, and a base 69 is installed on the side of the connecting block 67, a connecting plate 610 is vertically provided on the base 69, and a pressure plate 611 is vertically provided at the bottom of the connecting plate 610, and the pressure plate 611 is vertically provided on the upper end surface of the belt conveyor wheel 3.

[0029] In this embodiment, the user can control the rice conveying flow rate by controlling the limit height of the rice and cooperating with the transmission of the belt conveyor wheel 3, so that the rice conveyed in a single time can always be within the limited threshold. The user can also control the conveying speed of the belt conveyor wheel 3, and then cooperate with the flow limit of the height limiting component 6 to complete the stable control of the rice conveying flow rate. At the same time, the base 69 is used to drive the pressure plate 611 to move its position, so as to keep the rice at an appropriate stacking height during transportation and ensure the uniform transportation of the rice; it helps to improve the efficiency and stability of the belt conveyor wheel 3 and reduce downtime and production delays.

[0030] Specifically, refer to Figure 4 The pressing plate 611 is made entirely of rubber, and the bottom of the pressing plate 611 has rounded corners and an arc edge.

[0031] In this embodiment, the pressing plate 611 is made of rubber, which has soft properties and can adapt to the shape and height changes of rice. When the rice is piled too high, the pressing plate 611 can adapt to the limit height by pressing down and prevent the rice from being transported too high. At the same time, the rounded corners at the bottom can reduce the friction between the pressing plate 611 and the rice, thereby protecting the integrity and quality of the rice.

[0032] Specifically, refer to Figure 4 A threaded hole is provided on the connecting block 67, and the base 69 is detachably arranged on the side of the connecting block 67 by means of bolts.

[0033] In this embodiment, the base 69 is detachably provided on the connecting block 67, so that the connecting plate 610 and the pressure plate 611 can be disassembled and replaced together with the base 69 as a whole. When the cross-sectional size of the belt conveyor pulley 3 changes under different requirements, the user can change the length of the pressure plate 611, thereby making the height limit assembly 6 adaptable to the use of different models of belt conveyor pulleys 3. At the same time, the detachable bolt method is simple and fast.

[0034] Specifically, refer to Figure 4The adjustment plate 62 is set in a C shape. The top of the adjustment plate 62 is equipped with a bearing seat 63. A bearing is provided in the bearing seat 63. The top of the threaded screw 65 is rotatably connected to the bearing. The bottom of the adjustment plate 62 is equipped with a reciprocating motor 64. The output end of the reciprocating motor 64 is connected to the threaded screw 65.

[0035] In this embodiment, the bearings arranged in the bearing seat 63 can cooperate with the rotation of the threaded screw 65, so that the threaded screw 65 can rotate more smoothly when driven by the reciprocating motor 64. When in use, the user connects the reciprocating motor 64 to a power source. At this time, the reciprocating motor 64 is electrically driven to rotate, and at the same time drives the threaded screw 65 to rotate synchronously.

[0036] Specifically, refer to Figure 4 Two side limit columns 68 are provided on the adjustment plate 62. The two side limit columns 68 are respectively provided on one side of the slider seat 66 and pass through the slider seat 66 at the same time. The length of the pressure plate 611 is adapted to the width of the belt conveyor wheel 3.

[0037] In this embodiment, when the threaded screw 65 is rotating, the threaded screw 65 is limited by the side limit column 68, and can drive the connecting block 67 and the base 69 to perform radial lifting movement. Through the connection between the base 69 and the connecting plate 610, the pressure plate 611 is finally driven to perform lifting movement. Since the size of the pressure plate 611 is adapted to the transverse width of the belt conveyor wheel 3, the set pressure plate 611 can be completely fitted and tightly pressed against the surface of the belt conveyor wheel 3. When the user needs to stop conveying rice for a short time, the user can use the tight contact between the pressure plate 611 and the belt conveyor wheel 3 to make the rice blocked by the pressure plate 611 on the belt conveyor wheel 3 and stay for a short time, thereby avoiding stopping the belt conveyor wheel 3 as a whole and improving the conveying efficiency.

[0038] Specifically, refer to Figure 1-3 The collecting assembly 4 includes a side seat 41 arranged on the enclosure 2, and a mounting block 42 is provided on the upper end surface of the side seat 41. An adjusting rod 43 is slidably inserted into the mounting block 42. The ends of the two adjusting rods 43 on the same side are connected with a baffle 44. The baffle 44 is fitted on the upper end surface of the belt conveyor wheel 3, and a plurality of partition plates 45 are provided on the side of the baffle 44 along its horizontal direction.

[0039] In this embodiment, in actual use, the user pushes the adjustment rods 43 provided on both sides of the belt conveyor wheel 3, thereby allowing the baffle 44 and the partition plate 45 to move in opposite directions. At this time, the baffle 44 and the partition plate 45 block the rice, so that when the rice is conveyed on the belt conveyor wheel 3, it can be prevented from sliding off the upper end surface of the belt conveyor wheel 3, thereby preventing the rice from falling, thereby further improving the stable transportation of the rice.

[0040] Furthermore, by changing the spacing between the two baffles 44, the single conveying area of ​​the belt conveyor wheel 3 can also be adjusted, and the height of the pressure plate 611 can be moved downward to control the conveying flow rate. When the spacing between the two baffles 44 is reduced, the height of the pressure plate 611 is limited. At this time, the single conveying area of ​​the belt conveyor wheel 3 is reduced, and the single conveying flow rate is reduced. Similarly, when the spacing between the baffles 44 is expanded, the single conveying flow rate becomes larger.

[0041] It should be noted that the belt conveyor wheel 3 is an existing mature belt conveyor, and its conveying speed control method and circuit control are common knowledge in this field. It is only used without modification, so the control method and circuit connection are not described in detail.

[0042] The rice conveyor with adjustable conveying speed of the utility model:

[0043] Step 1: When the user is conveying rice, the rice is poured onto the belt conveyor wheel 3, and then the reciprocating motor 64 is connected to a power source. At this time, the reciprocating motor 64 is driven to rotate, and at the same time, the threaded screw 65 is driven to rotate synchronously. The threaded screw 65 is limited by the side limit column 68, and then the connecting block 67 and the base 69 are driven to perform radial lifting movement. The base 69 and the connecting plate 610 are connected to finally drive the pressing plate 611 to perform lifting movement. The user can control the number of rotations of the threaded screw 65 to control the descending height of the pressing plate 611, thereby completing the height limit of the rice conveying.

[0044] Step 2: When limiting the height of rice, the user pushes the adjustment rods 43 provided on both sides of the belt conveyor wheel 3, thereby allowing the baffle 44 and the partition plate 45 to move in opposite directions. At this time, the baffle 44 and the partition plate 45 prevent the rice from sliding off the upper end surface of the belt conveyor wheel 3 when being conveyed on the belt conveyor wheel 3, thereby preventing it from falling, thereby further improving the stable conveying of rice. At the same time, the two baffles 44 with variable spacing can also adjust the single conveying area of ​​the belt conveyor wheel 3, and cooperate with the downward movement of the pressure plate 611 to achieve control of the conveying flow rate.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
