DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying 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.

[0025] Reference Figure 1-7 A lifting device for rice processing includes a support base 1, two guide support plates 2 are fixedly arranged on the upper end surface of the support base 1, the cross-section of the guide support plate 2 is J-shaped, a rice lifting component is arranged between the two guide support plates 2, and a rice storage box 3 is arranged on the rice lifting component.

[0026] The rice lifting assembly includes a transmission gear 4 rotatably arranged between two guide support plates 2, two transmission gears 4 are provided, a chain 5 is connected between the two transmission gears 4, a connecting frame 6 is fixedly provided on the chain 5, and a connecting plate 7 is fixedly provided on the connecting frame 6. A plug rod 8 is fixedly provided on the connecting plate 7, two plug rods 8 are provided, a push rod 9 is fixedly provided on the plug rod 8, one end of the push rod 9 is fixedly connected to the connecting plate 7, and an end of the plug rod 8 away from the connecting plate 7 is provided with an external thread, a servo motor 10 is fixedly provided on one of the guide support plates 2, and the output end of the servo motor 10 is connected to a transmission gear 4. A plug pipe 11 is fixedly provided on the rice storage box 3, two plug pipes 11 are provided, and the two plug pipes 11 correspond to the positions of the two plug rods 8 respectively, and the two plug rods 8 are respectively inserted in the two plug pipes 11. The insertion rods 8 are sleeved with nuts 12, which are connected to the insertion rods 8 by threads, and one end of the nuts 12 is placed on the end of the insertion tube 11 on the rice storage box 3. The lower end surface of the rice storage box 3 is fixed with casters 13, and two hand push handles 130 are fixed on the rice storage box 3 in sequence. A limit position assembly is provided on the guide support plate 2. The hand push handles 130 and casters 13 are provided to facilitate the movement of the rice storage box 3.

[0027] In this example: first, the rice storage box 3 is pushed to one side of the connecting plate 7, and the insertion rod 8 on the rice storage box 3 is inserted into the insertion tube 11 on the rice storage box 3, and then the nut 12 is threadedly connected to the insertion rod 8, so that the rice storage box 3 is fixedly connected to the insertion rod 8, and then the rice to be processed is added to the rice storage box 3. After the rice in the rice storage box 3 is added in an appropriate amount, the servo motor 10 is started. The start of the servo motor 10 drives the transmission gear 4 connected thereto to rotate, and the rotation of the transmission gear 4 drives the rotation of another transmission gear 4 through the chain 5. The chain 5 passes through the connecting frame 6 during the rotation process. The connecting plate 7 is driven to move upward along the guide support plate 2, and the movement of the connecting plate 7 drives the rice storage box 3 connected to the rice storage box 3 to move. When the rice storage box 3 moves to the curved portion at the top of the guide support plate 2, the rice storage box 3 will tilt along the curvature of the top of the guide support plate 2. When the rice storage box 3 is tilted to a certain angle, the rice in the rice storage box 3 will be poured into the rice processing equipment for processing. After the rice in the rice storage box 3 is poured out, the servo motor 10 is started in reverse to restore the rice storage box 3 to its original position, and the above steps are repeated to lift the rice to be processed and add it into the rice processing equipment.

[0028] The setting of the rice lifting component replaces the traditional rice lifting method which needs to be completed by a conveyor belt, which can avoid the rice rolling on the conveyor belt during the lifting process and causing the rice to be accumulated at the feeding place of the conveyor belt; in addition, the rice lifting component can also lift the rice to be processed in batches to the rice processing equipment for processing, which can speed up the lifting efficiency of the rice.

[0029] The limiting assembly includes a fixed block 14 fixedly arranged on the guide support plate 2, a limiting telescopic rod 15 fixedly arranged on the fixed block 14, a limiting block 16 fixedly arranged on the top of the limiting telescopic rod 15, a coil spring 17 sleeved on the limiting telescopic rod 15, and two ends of the coil spring 17 are fixedly connected to the fixed block 14 and the limiting block 16 respectively.

[0030] In this example: when the rice storage box 3 moves along the guide support plate 2, when the top end of the rice storage box 3 is placed on the limit block 16, the limit block 16 is forced to squeeze the limit telescopic rod 15 and the coil spring 17, the limit telescopic rod 15 is forced to contract, and the coil spring 17 is forced to deform, thereby limiting the rice storage box 3 from continuing to move along the support plate 2. When the limit telescopic rod 15 contracts to the maximum value, the limit block 16 prevents the rice storage box 3 from continuing to move along the support plate 2.

[0031] The setting of the limit assembly can not only limit the moving range of the rice storage box 3, but also provide a buffer for the rice storage box 3 when limiting the moving range, thereby preventing the rice storage box 3 from directly hitting the limit block 16 and causing damage to the rice storage box 3.

[0032] A buffer assembly is provided on the support base 1, and the buffer assembly includes a buffer rod 18 fixedly provided on the support base 1, and the positions of the buffer rod 18 and the connecting plate 7 correspond to each other. A buffer block 19 is fixedly provided on the top of the buffer rod 18, and a buffer spring 20 is sleeved on the buffer rod 18. The two ends of the buffer spring 20 are fixedly connected to the buffer block 19 and the support base 1 respectively.

[0033] In this example: when the rice storage box 3 is in the process of restoring its original position and is about to restore to the bottom of its stroke, the connecting plate 7 will first be pressed against the top of the buffer block 19, and the buffer block 19 will be contracted by force, and the buffer spring 20 will be deformed by force, thereby reducing the downward movement speed of the rice storage box 3 on the connecting plate 7. The setting of the buffer assembly can reduce the downward movement speed of the rice storage box 3, thereby reducing the inertia of the rice storage box 3 when it moves down to the ground, thereby reducing the problem of the rice storage box 3 being damaged by the large inertia when it moves down to the ground.

[0034] A tensioning assembly is provided between the two guide support plates 2, and the tensioning assembly includes a fixing frame 21 fixedly provided on one guide support plate 2, a tensioner 22 fixedly provided on the fixing frame 21, a tensioning gear 23 fixedly provided on the tensioner 22, and the tensioning gear 23 connected to the chain 5. The setting of the tensioning assembly can ensure that the chain 5 between the two transmission gears 4 is always kept in a taut state, and prevent the chain 5 between the two transmission gears 4 from becoming loose and causing the chain 5 to fall off from between the two transmission gears 4.
