Description

Technical Field

[0001] The invention relates to the technical field of rice production devices, in particular to a rice flattening device for rice production. Background Art

[0002] The rice paving device for rice production is a mechanical device used to pave rice during the rice production process. The device usually includes a feed frame, a paving mechanism, a shaking mechanism and a support structure. The feed frame is used to receive and temporarily store rice, and its design is usually convenient for the uniform distribution and flow of rice. The paving mechanism is responsible for paving the rice in the feed frame to ensure that the rice can be evenly distributed during the subsequent processing to avoid local accumulation or vacancies. The shaking mechanism helps the rice to be looser and more uniform during the paving process by vibration or shaking. This mechanism usually works in conjunction with the paving mechanism to improve the paving effect. The support structure is used to support and fix the entire device to ensure its stability and durability. In addition, some advanced paving devices are also equipped with an automatic control system, which can automatically adjust the paving speed and shaking force according to production needs to improve production efficiency and product quality. The rice paving device for rice production is one of the important equipment in the rice processing production line. Its performance and quality are of great significance to ensure the smooth progress of rice production and improve product quality.

[0003] For example, the Chinese authorized patent "A rice flattening device for rice production" with announcement number CN118637391B includes a first feed frame and a hopper. Four groups of first springs are fixedly connected to the bottom end of the first feed frame, and the bottom end of the first spring is fixedly connected to the top of the fixed frame. The first springs are located at the four corners of the first feed frame, and the bottom end of the fixed frame is fixedly connected to a support column. The hopper is located directly below the fixed frame. A flattening mechanism is provided on the first feed frame, and the flattening mechanism is used to flatten the rice in the first feed frame. A first shaking mechanism is provided at the bottom end of the first feed frame, and the first shaking mechanism is used to shake the rice in the first feed frame. A second shaking mechanism is provided on the fixed frame. Through the structural design of the flattening mechanism, the rice poured into the first feed frame can be flattened to avoid the occurrence of excessively high rice piles in some parts.

[0004] Although the above-mentioned prior art can level the rice, in the process of transporting the rice to the rice bin, on the one hand, the agglomerated rice is not easy to pass through the screen, and over time, a blockage is formed at the front end of the leveling mechanism, which not only affects the rice leveling effect, but also causes additional workload. On the other hand, the traditional rice leveling structure has a poor coverage area. Although there will be no rice piles, the surface is still uneven after the rice is leveled. Therefore, it does not meet the existing needs. In this regard, we propose a rice leveling device for rice production. Summary of the invention

[0013] Preferably, a rice-leveling net is provided inside the rice-laying mechanism, three rice-leveling nets are provided, and the rice-leveling nets are engaged with the rice-laying mechanism.

[0014] Preferably, an arc-shaped baffle is provided at the upper end at the middle position of the feeding cavity, and both ends of the arc-shaped baffle are fixed to the V-shaped groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention is provided with a reciprocating swinging rice-spreading mechanism. During the rice-spreading process, rice enters the rice-spreading mechanism through a flexible rice-feeding sleeve. By turning on the driving motor, the output shaft of the driving motor drives the sector gear to rotate. When the outer gear ring of the sector gear contacts the first rack at the upper end of the interior of the transmission frame, the rotational motion is converted into linear motion under the meshing action, so that the transmission frame moves to one side, and then drives the rice-spreading mechanism to move to one side through the movable frame, so that the moving area is spread with rice. During the movement, the transmission gear inside the transmission seat at the bottom of the movable frame is combined with the second rack on the inner side of the side plate. Similarly, the movable frame forms the rotation of the transmission gear during the movement, thereby driving the upper active sector bevel gear to rotate. When the gear ring of the active sector bevel gear meshes with the driven bevel gear, it drives the connecting shaft to rotate, so that the rice-spreading mechanism swings in one direction. With the continuous rotation of the transmission gear, the gear of the active sector bevel gear After the ring loses engagement with the driven bevel gear, the torsion spring quickly swings and resets in the other direction, forming a high-frequency swing of the rice-spreading mechanism in turn. At the same time, a three-layer rice-leveling net is provided inside the rice-spreading mechanism, which can quickly and evenly distribute the rice entering the rice-spreading mechanism from the flexible rice feeding sleeve, ensuring that the rice discharged from the rice-spreading mechanism can maintain a uniformly dispersed discharging state. As the fan-shaped gear continues to rotate, the outer gear ring of the fan-shaped gear and the first rack at the lower end of the transmission frame form the rice-spreading mechanism, and similarly drive the rice-spreading mechanism to move to the other side through the movable frame. At the same time, the rice-spreading mechanism still maintains high-frequency swing during the movement toward the other side. Under the reciprocating reset of the rice-spreading mechanism, combined with the rice-spreading method of constantly swinging to level the rice, the rice can be evenly spread layer by layer on the upper end of the rice bin, so that accumulation and waste of rice can be avoided during the spreading process, thereby improving the efficiency and quality of rice spreading.

[0016] 2. The present invention is provided with an anti-caking feeding mechanism. After the staff pours the rice into the rice storage box, under the guidance of the V-shaped groove, the rice can be continuously gathered toward the bottom center until it enters the feeding chambers on both sides. During the operation of the driving motor on one side, the driving pulley on its output shaft drives the first driving pulley to rotate under the transmission of the first driving belt. The first driving pulley drives the second driving pulley equipped with the driven gear to rotate under the meshing action of the driving gear at the front end. The shaft inside the second driving pulley is fixed to the conveying shaft of the feeding mechanism on one side, so that the corresponding spiral conveying blades rotate During the operation of the driving motor on the other side, the active pulley on the output shaft drives the rotating shaft of the second transmission pulley under the action of the first transmission belt, thereby realizing the rotation of the conveying shaft in the feeding mechanism on the other side. On the one hand, the spiral conveying blades on both sides rotate in opposite directions, and can continuously push the rice entering the feeding chamber toward the center. On the other hand, the spacing of the spiral conveying blades decreases from the side close to the transmission mechanism to the other side, continuously squeezing the rice being conveyed, thereby crushing the clumped rice and keeping it in a dispersed and independent state after entering the rice spreading mechanism through the flexible rice feeding sleeve.

[0017] 3. The present invention arranges a scattering mechanism inside the rice storage box. The second transmission pulley in the transmission mechanism on one side drives the driven pulley to rotate forwardly through the second transmission belt during the rotation process, thereby realizing that the scattering shafts on the two groups of outer scattering mechanisms drive the scattering rods to rotate forwardly. Due to the lack of reversing of the gear ring, the second transmission pulley in the transmission mechanism on the other side drives the driven pulley to rotate reversely through the second transmission belt during the rotation process, thereby realizing that the scattering shafts on the other two groups of inner scattering mechanisms drive the scattering rods to rotate reversely, forming that the rotation directions of adjacent scattering mechanisms are opposite, and the scattering rods on adjacent scattering mechanisms are staggered, ensuring that the scattering mechanism can fully and evenly cover every corner in the rice storage box during the rotation process, thereby improving the scattering effect, avoiding the generation of dead angles in the scattering process, and ensuring that the rice can be fully scattered. By arranging a scattering mechanism inside the rice storage box, effective scattering of the rice can be achieved. When the rice enters the rice storage box, the breaking rod will continuously stir and break the rice due to the rotation of the breaking shaft, so as to prevent the rice from forming lumps or clusters during storage. The setting of the breaking mechanism helps to improve the fluidity of the rice. When the rice is effectively broken up, the gaps between its particles increase, allowing the rice to flow more smoothly during transportation, reducing the risk of blockage and stagnation.

At the same time, the sliding limit design of the movable frame 9, the transmission frame 21 and the displacement driving mechanism 7 ensures the stability and accuracy of the rice-laying mechanism 9 during the movement.

[0022] See also Figure 3 , Figure 4A sector gear 20 is provided inside the transmission frame 21, and the shaft at the outer end of the sector gear 20 is rotatably connected to the displacement driving mechanism 7. The upper and lower ends of the inner cavity of the transmission frame 21 are provided with a first rack 19, and the first rack 19 is meshed with the sector gear 20.

A rice-leveling net 18 is provided inside the rice spreading mechanism 9. Three rice-leveling nets 18 are provided, and the rice-leveling nets 18 are engaged with the rice spreading mechanism 9. Through the rotation of the driving motor 11 and the meshing action of the sector gear 20 and the first rack 19, the rotational motion is converted into a linear motion of the transmission frame, thereby driving the rice spreading mechanism 9 to move back and forth.

The three-layer rice-leveling net 18 design inside the rice spreading mechanism 9 enables the rice entering from the flexible rice feeding sleeve 17 to be quickly and evenly distributed. This ensures that the rice discharged from the rice spreading mechanism 9 can remain evenly dispersed, avoiding accumulation and waste.

[0023] See also Figure 4 , Figure 5 and Figure 6 A second rack 22 is installed at the lower end of the inner side of the side plate 6, and a transmission gear 25 is rotatably installed on the outer side of the lower end of the transmission seat 23, and the transmission gear 25 is meshingly connected with the second rack 22.

Through the meshing of the transmission gear 25 with the second rack 22, and the meshing of the active sector bevel gear 26 with the driven bevel gear 27, high-frequency swing of the rice-laying mechanism 9 during movement is achieved. This swing mechanism ensures that the rice spreading mechanism can evenly and efficiently cover the entire rice spreading area, avoids the accumulation and waste of rice during the spreading process, and improves the efficiency and quality of rice spreading.

This automatic reset function ensures the continuity and stability of the rice spreading mechanism during the swinging process, and further improves the rice spreading effect.

[0024] See also Figure 1 and Figure 7, a driving pulley 29 is rotatably installed at the lower end of the transmission mechanism 10, and the driving pulley 29 is keyed to the output shaft of the drive motor 11, a second transmission pulley 33 is rotatably installed at the upper end of the transmission mechanism 10, and a driven pulley 35 is rotatably installed at the front and rear of the upper end of the transmission mechanism 10, and the driven pulley 35 is connected to the second transmission pulley 33 through a second transmission belt 36; a first transmission pulley 30 is rotatably installed at the middle position of the transmission mechanism 10 on one side, and the first transmission pulley 30 is connected to the driving pulley 29 through a first transmission belt 31, a driving gear 32 is installed at the front end of the first transmission pulley 30, and the front end of the second transmission pulley 33 is fixed A driven gear 34 is installed, and the driven gear 34 is meshed with the driving gear 32; the second drive pulley 33 inside the transmission mechanism 10 on the other side is directly connected to the driving pulley 29 through the first transmission belt 31, and the transmission mechanism on one side realizes the reversal from the driving pulley 29 to the second drive pulley 33 through the meshing of the first drive pulley 30, the driving gear 32 and the driven gear 34, and the transmission mechanism on the other side directly transmits the power of the driving pulley 29 to the second drive pulley 33 through the first transmission belt 31, which reduces the complexity and cost of the device, while improving the reliability and stability of the transmission, and realizes the synchronous driving of the feeding mechanism 4, the scattering mechanism 5 and the rice spreading mechanism 9. This linkage transmission effect not only improves the working efficiency of the entire device, but also ensures the coordination between the various mechanisms, thereby realizing the effective flattening and scattering of rice.

[0025] See also Figure 1 , Figure 2 and Figure 3 The two groups of feeding mechanisms 4 include a conveying shaft 12, and the conveying shaft 12 is rotatably connected to the rice storage box 1. A plurality of spiral conveying blades 13 are arranged on the outside of the conveying shaft 12, and the spacing of the spiral conveying blades 13 gradually decreases from one side close to the transmission mechanism 10 to the other side. The conveying shaft 12 on the feeding mechanism 4 is respectively fixed to the output shaft on the second transmission pulley 33 in the two groups of transmission mechanisms 10 through a coupling. Since the spiral conveying blades 13 on both sides rotate in opposite directions, the rice entering the feeding cavity 16 can be continuously pushed toward the center. On the other hand, the spacing of the spiral conveying blades 13 decreases from one side close to the transmission mechanism to the other side, and the rice being transported is continuously squeezed, thereby crushing the agglomerated rice, so that it can remain dispersed and independent after entering the rice spreading mechanism 9 through the flexible rice feeding sleeve 17, thereby improving the fluidity of the rice and reducing the risk of blockage and stagnation.

[0026] See also Figure 1 , Figure 2 and Figure 3The four groups of scattering mechanisms 5 include a scattering shaft 14, and the scattering shaft 14 is rotatably connected to the rice storage box 1. The outside of the scattering shaft 14 is provided with three annularly distributed scattering rods 15, and the scattering rods 15 on two adjacent groups of scattering mechanisms 5 are staggered. The shaft of the driven pulley 35 in the transmission mechanism 10 on one side is fixed to the scattering shafts 14 of the two outer groups of scattering mechanisms 5 through a coupling, and the shaft of the driven pulley 35 in the transmission mechanism 10 on the other side is fixed to the scattering shafts 14 of the two inner groups of scattering mechanisms 5 through a coupling. The rotation directions of adjacent scattering mechanisms 5 are opposite, and the scattering rods 15 on adjacent scattering mechanisms 5 are staggered, ensuring that the scattering mechanism 5 can fully and evenly cover every corner in the rice storage box during the rotation process, thereby improving the scattering effect, avoiding dead angles during the scattering process, and ensuring that the rice can be fully scattered.

[0027] Working principle: When in use, after the staff pours the rice into the rice storage box 1, the rice is continuously gathered toward the bottom center under the guidance of the V-shaped groove 2. During the operation of the driving motor 11, the second transmission pulley 33 in the transmission mechanism 10 on one side drives the driven pulley 35 to rotate forward through the second transmission belt 36 during the rotation process, thereby realizing that the scattering shafts 14 on the two groups of outer scattering mechanisms 5 drive the scattering rods 15 to rotate forward. Due to the lack of reversing of the gear ring, the second transmission pulley 33 in the transmission mechanism 10 on the other side drives the driven pulley 35 to rotate in the opposite direction through the second transmission belt 36 during the rotation process, thereby realizing that the scattering shafts 14 on the other two groups of inner scattering mechanisms 5 drive the scattering rods 15 to rotate in the opposite direction. The rotation directions of adjacent scattering mechanisms 5 are opposite, and the scattering rods 15 on adjacent scattering mechanisms 5 are staggered, ensuring that the scattering mechanism 5 can fully and evenly cover every corner in the rice storage box 1 during the rotation process, avoiding dead angles during the scattering process, ensuring that the rice can be fully scattered until the rice enters the feeding chamber 16 on both sides. During the operation of the driving motor 11 on one side, the driving pulley 29 on its output shaft drives the first driving pulley 30 to rotate under the transmission of the first transmission belt 31, and the first driving pulley 30 drives the second driving pulley 33 equipped with a driven gear 34 to rotate under the meshing action using the driving gear 32 at the front end. The shaft inside the second driving pulley 33 is fixed to the conveying shaft 12 of the feeding mechanism 4 on one side, so as to realize the rotation of the corresponding spiral conveying blade 13. During the operation of the driving motor 11 on the other side, the driving pulley 29 on the output shaft drives the second driving pulley 33 rotating shaft under the action of the first transmission belt 31, thereby realizing the rotation of the conveying shaft 12 in the feeding mechanism 4 on the other side. On the one hand, the spiral conveying blades 13 on both sides rotate in opposite directions, and can continuously push the rice entering the feeding chamber 16 toward the center; on the other hand, the spacing of the spiral conveying blades 13 decreases from one side close to the transmission mechanism 10 to the other side, and continuously squeezes the rice being transported, so as to crush the lumped rice, and the rice that has been broken up will enter the flexible rice delivery sleeve 17 through the feeding chamber 16. After the rice enters the flexible rice delivery sleeve 17, it will enter the rice spreading mechanism 9. At this time, the rice uniformity net 18 inside the rice spreading mechanism 9 will quickly and uniformly spread the rice. The output shaft of the driving motor 11 drives the sector gear 20 to rotate. When the outer gear ring of the sector gear 20 contacts the first rack 19 at the upper end of the transmission frame 21, the rotational motion is converted into linear motion under the meshing action, so that the transmission frame 21 moves to one side. Then, the rice spreading mechanism 9 is driven to move to one side through the movable frame 8, and the rice is spread flat in the moving area. During the movement, the transmission gear 25 inside the transmission seat 23 at the bottom of the movable frame 8 is combined with the second rack 22 inside the side plate 6. Similarly, the movable frame 8 forms a rotation of the transmission gear 25 during the movement, thereby driving the upper active sector bevel gear 26 to rotate.When the toothed ring of the active sector bevel gear 26 meshes with the driven bevel gear 27, the connecting shaft is driven to rotate, thereby realizing the rice-laying mechanism 9 to swing in one direction. As the transmission gear 25 rotates continuously, after the toothed ring of the active sector bevel gear 26 loses meshing with the driven bevel gear 27, the rice-laying mechanism 9 is quickly swung and reset in the other direction under the action of the torsion spring 28. The high-frequency swing of the rice-laying mechanism 9 is formed in sequence, and at the same time, a three-layer rice-leveling net 18 is provided inside the rice-laying mechanism 9, which can make the rice entering the rice-laying mechanism 9 from the flexible rice-feeding sleeve 17 be quickly evenly distributed, ensuring that the rice discharged from the rice-laying mechanism 9 can maintain a state of uniformly dispersed discharging. As the sector gear 20 continues to rotate, the outer toothed ring of the sector gear 20 contacts the first rack 19 at the lower end of the transmission frame 21, and similarly drives the rice-laying mechanism 9 to move to the other side through the movable frame 8. At the same time, the rice-laying mechanism 9 still maintains a high-frequency swing during the movement to the other side. Under the reciprocating movement of the rice-spreading mechanism 9, in combination with the rice-spreading method of constantly swinging the rice, the rice can be evenly spread layer by layer on the upper end of the rice bin.
