Description

Technical Field

[0001] This utility model relates to the technical field of rice conveying mechanisms, specifically a rice conveying mechanism for a rice processing production line. Background Technology

[0002] In the rice production process, raw rice needs to be transported to a cylindrical primary cleaning screen and a vibrating screen to remove large particles of impurities such as straw and sand. After steps such as destoning, magnetic separation, dehulling, rice separation, milling, and polishing, white rice is produced. During the rice transportation process, a scraper conveyor is used. A scraper conveyor generally consists of a shell, an inlet, an outlet, a scraper chain, and a drive module. In use, rice enters through the inlet, and the drive module drives the scraper chain to rotate, causing the scraper chain to disperse the rice under the squeezing action of the inner wall of the shell and discharge it from the outlet.

[0003] As can be seen from the above, the existing scraper conveyors used for rice conveying have the following defects when in use: After rice enters the scraper conveyor, although the scrapers on both sides can push the rice out smoothly, a lot of rice will remain in the middle of the scraper chain. The scrapers have difficulty pushing out the rice in this position, resulting in residual material in this position. If the residual material is not discharged in time, bacteria will grow, resulting in damage to the quality of the rice. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rice conveying mechanism for a rice processing production line, which allows residual rice remaining in the box to be discharged smoothly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rice conveying mechanism for a rice processing production line, comprising a scraper conveyor, a drive structure connected to the outside of the scraper conveyor, multiple scraper chains connected to the inside of the scraper conveyor, an inlet connected to the top of the scraper conveyor housing, and an outlet connected to the bottom of the scraper conveyor. The bottom of the scraper conveyor housing is connected to two symmetrically arranged base plates, both of which are rotatably connected to the scraper conveyor housing. A push structure is connected to the bottom of each base plate, and side baffle structures are fixedly connected to both sides of each base plate.

[0006] Furthermore, the pushing structure includes an electric actuator, the top of which is rotatably connected to the base plate.

[0007] Furthermore, the side baffle structure is composed of a thickened plate and an L-shaped outer side plate. The thickened plate is fixedly connected to the bottom of the base plate, and the outer wall of the thickened plate is fixedly connected to the L-shaped outer side plate. The inner wall of the L-shaped outer side plate is slidably connected to the outer wall of the scraper conveyor housing.

[0008] Furthermore, the scraper conveyor is fixedly connected to the bottom of both ends with a U-shaped base, and two brackets are fixedly connected to the top surface of the base. The bottom of the two electric push rods is rotatably connected to the top surface of the brackets.

[0009] Furthermore, the top surface of the base is also connected to a receiving box for receiving excess material, and the opening of the receiving box is located below the end of the two base plates away from the hinge.

[0010] Furthermore, the outer wall of the L-shaped outer side plate is connected with fasteners for securing the L-shaped outer side plate.

[0011] Furthermore, the fastener is a bolt rod, which passes through the L-shaped outer side plate and is threadedly connected to the housing of the scraper conveyor.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model replaces the original sealed bottom of the scraper conveyor with two symmetrically rotatable bottom plates, so that the bottom plates can be tilted after opening, so that the residual material can be smoothly discharged, avoiding the accumulation of residual material and the inability to clean the inside, which would cause the rice to mold and affect subsequent batches. The structure is simple, easy to operate and highly practical. 2. By setting up the thickened plate and the L-shaped outer plate, when the bottom plate is opened, the thickened plate and the L-shaped outer plate unfold with the bottom plate to discharge the excess material. This setting can prevent the excess material from spilling from both sides of the bottom plate at the moment the bottom plate is opened. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] like Figures 1 to 5 As shown, a rice conveying mechanism for a rice processing production line includes a scraper conveyor 1, a drive structure 2 connected to the outside of the scraper conveyor 1, multiple scraper chains 11 connected to the inside of the scraper conveyor 1, an inlet 3 connected to the top of the scraper conveyor 1 housing, and an outlet 10 connected to the bottom of the scraper conveyor 1. Two symmetrically arranged base plates 4 are connected to the bottom of the scraper conveyor 1 housing, and both base plates 4 are rotatably connected to the scraper conveyor 1 housing. A push structure is connected to the bottom of the base plate 4, and side baffle structures 5 are fixedly connected to both sides of the base plate 4.

[0017] like Figures 1 to 5 As shown, when the rice conveying mechanism of the rice processing production line of this utility model needs to clean the residual material at the bottom of the scraper conveyor 1, the pushing structure can be activated to extend and retract, thereby driving the bottom plate 4 to open with the end hinge. After the two symmetrically arranged bottom plates 4 are opened, the bottom plates 4 are in an inclined state and separate from the scraper chain 11. At this time, the bottom plates 4 can guide the residual material to slide out, thereby cleaning the residual material remaining on the inner wall of the bottom plates 4.

[0018] By changing the original sealed state of the scraper conveyor 1 to two symmetrically rotatable bottom plates 4, the bottom plates 4 can be tilted after opening, so that the residual material can be smoothly discharged, avoiding the accumulation of residual material inside the machine, which may cause the rice to mold and affect subsequent batches.

[0019] It is worth noting that when the bottom plate 4 is joined, the bottom of the bottom plate 4 and the scraper conveyor 1 should be sealed to prevent the rice from being exposed.

[0020] like Figure 2 and Figure 3 As shown, the pushing structure includes an electric actuator 8, the top of which is rotatably connected to the base plate 4.

[0021] Specifically, when the base plate 4 needs to be rotated, the electric actuator 8 can be activated. The output end of the electric actuator 8 retracts, causing the base plate 4 to rotate and open. The top and bottom ends of the electric actuator 8 are rotatably connected, which ensures that the electric actuator 8 can smoothly open the base plate 4.

[0022] After the base plate 4 is assembled, the electric push rod 8 acts as a support, pressing the base plate 4 against the bottom of the housing to prevent the base plate 4 from rotating and loosening.

[0023] like Figure 4 and Figure 5As shown, the side baffle structure 5 is composed of a thickened plate 51 and an L-shaped outer plate 52. The thickened plate 51 is fixedly connected to the bottom of the base plate 4, and the outer wall of the thickened plate 51 is fixedly connected to the L-shaped outer plate 52. The inner wall of the L-shaped outer plate 52 is slidably connected to the outer wall of the scraper conveyor 1.

[0024] Specifically, in order to prevent rice from scattering from both sides after the bottom plate 4 is opened, when the bottom plate 4 is opened, the thickening plate 51 and the L-shaped outer side plate 52 are simultaneously unfolded, so that the thickening plate 51 and the L-shaped outer side plate 52 unfold with the bottom plate 4 to discharge the excess material.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the scraper conveyor 1 has U-shaped bases 9 fixedly connected to the bottom of both ends. Two brackets 7 are fixedly connected to the top surface of the bases 9, and the bottom of the two electric push rods 8 are rotatably connected to the top surface of the brackets 7.

[0026] Specifically, the base 9 ensures that the base plate 4 has enough space to unfold, and the bracket 7 ensures the stable installation of the electric actuator 8.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the top surface of the base 9 is also connected to a receiving box 6 for receiving excess material. The opening of the receiving box 6 is located below the end of the two base plates 4 away from the hinge.

[0028] Specifically, the receiving box 6 ensures that the discharged excess material is collected. It is worth noting that the end of the L-shaped outer panel 52 is also located inside the opening of the receiving box 6, thus preventing the excess material discharged from the L-shaped outer panel 52 from falling outside the receiving box 6.

[0029] like Figure 3 and Figure 4 As shown, the outer wall of the L-shaped outer side plate 52 is connected to fasteners 12 for securing the L-shaped outer side plate 52.

[0030] Specifically, the L-shaped outer side plate 52 can be further restricted by the fastener 12 to prevent damage to the supporting force of the electric push rod 8, which could cause the base plate 4 to open suddenly.

[0031] like Figure 3 and Figure 4 As shown, the fastener 12 is a bolt rod, which passes through the L-shaped outer plate 52 and is threadedly connected to the housing of the scraper conveyor 1.

[0032] Specifically, by setting bolt rods on fastener 12, the bolt rods can be threadedly connected to the housing of scraper conveyor 1 on the outer wall of L-shaped outer plate 52, thus ensuring the overall stability of base plate 4.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
