Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a rice processing and conveying device. Background Art

[0002] Rice is a finished product made from paddy rice after processes such as cleaning, husking, milling, and finishing. Rice contains nearly 64% of the nutrients in rice and more than 90% of the nutrients needed by the human body. It is also the staple food of people in most parts of my country. Rice is an indispensable part of people's life. Rice production is becoming more and more mechanized. In the process of processing paddy rice into rice, transporting rice is one of the necessary steps.

[0003] In the related art, a Chinese patent document with application number CN202322080007.6 proposes a conveying device for rice processing, which fixes different numbers of conveying tubes between the feed tube and the discharge tube with screws according to different conveying distances. While fixing, the first clamping block and the first clamping groove are clamped and fixed to each other, and the second clamping block and the second clamping groove are clamped and fixed to each other. Rice is put into the feed tube through the feed port, and the servo motor is turned on to drive the third rotating shaft to rotate. Under the action of the third rotating shaft, the second rotating shaft and the first rotating shaft are driven to rotate, so that the rice is moved to the discharge port under the action of the first conveying blade, the second conveying blade and the third conveying blade. During the conveying process, the fan can also be turned on so that the wind passes through the first blowing hole, the second blowing hole and the third blowing hole to cool the rice.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the device feeds rice into the device body through a feed pipe, and connects an external power supply of a servo motor. When the servo motor works, it drives the third rotating shaft to rotate, and the third rotating shaft drives the third conveying blade to rotate. The third conveying blade cooperates with the discharge pipe to convey the rice. However, since some broken rice is mixed in the rice, the conveying device does not pick out the broken rice during the rice conveying process, which affects the taste of the rice after the broken rice is processed. In view of this, a rice processing and conveying device is proposed to solve the above-mentioned problem. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 A rice processing and conveying device in this embodiment includes a conveying cylinder 1, a rotatable auger 2 is horizontally arranged in the conveying cylinder 1, a rotating motor 3 for driving the auger 2 to rotate is fixed on the conveying cylinder 1, a filter box 5 is fixed above the conveying cylinder 1, a feed inlet 6 is opened at the upper end of the filter box 5, a filter mechanism 7 is arranged in the filter box 5, and a discharge pipe 4 is arranged at one end of the conveying cylinder 1.

[0022] The filtering mechanism 7 includes a guide rod 705, an opening 704, a collecting box 701, a side box 712 and a second rotating shaft 709. Two guide rods 705 are obliquely arranged in the filter box 5, and a filter screen 706 is slidably installed on the guide rods 705. A rotatable second rotating shaft 709 is horizontally arranged in the filter box 5. One end of the second rotating shaft 709 is driven to rotate by an external motor. Two gears 708 are fixed on the second rotating shaft 709. A rack 710 meshing with the gear 708 is fixed at the lower end of the filter box 5. A plurality of clips are missing on the outer side of the gear 708. A spring 707 is sleeved on the guide rod 705, and both ends of the spring 707 are respectively fixed to the right side of the filter screen 706 and the right side wall of the inner cavity of the filter box 5.

[0023] The device starts an external motor, which drives the second shaft 709 to rotate, and the second shaft 709 drives the gear 708 to rotate, and the gear 708 engages with the rack 710 to drive the filter 706 to move to the left. At this time, the filter 706 pulls the spring 707. When the gear 708 rotates to the outside where the clip is missing, the gear 708 no longer engages with the rack 710, and the retractability of the spring 707 drives the filter 706 to retract to its initial state, and the filter 706 is screened in this reciprocating manner.

[0024] A side box 712 is fixed to one side of the filter box 5 , and an opening 704 is provided on one side of the filter box 5 to facilitate screening of qualified large logs to flow into the conveying cylinder 1 .

[0025] At the same time, one side of the guide rod 705 is fixed to the side wall of the inner cavity of the side box 712, the lower end of the side box 712 is connected to the upper end of the conveying cylinder 1, one end of the filter screen 706 is located in the side box 712, and the filter screen 706 is slidably connected to the opening 704. One end of the filter screen 706 is located in the side box 712, so that qualified large wood can fall into the side box 712, and unqualified rice can fall into the collection box 701 from the holes in the filter screen 706.

[0026] In addition, a collecting box 701 for collecting broken rice is slidably installed at the bottom of the inner side of the filter box 5. A through hole 711 is provided at the opening of the filter net 706. The guide rod 705 is slidably connected to the through hole 711 to increase the stability of the filter net 706 when swinging left and right.

[0027] See also Figure 2 The filtering mechanism 7 in this embodiment includes a first rotating shaft 702 . A rotatable first rotating shaft 702 is horizontally arranged in the filter box 5 . A plurality of fan blades 703 are fixed to the outside of the first rotating shaft 702 . The first rotating shaft 702 is located in the middle of the lower end of the feed port 6 .

[0028] The device allows rice to fall from the feed port 6 onto the fan blade 703 , and then the fan blade 703 evacuates and quantitatively distributes the fallen rice, and then the rice falls onto the screen, thereby preventing the rice from piling up on the filter screen 706 .

[0029] The working principle of the above embodiment is:

[0030] When broken rice in the rice needs to be screened, the rice first falls from the feed inlet 6 onto the fan blade 703, and then the fan blade 703 evacuates and quantitatively distributes the fallen rice, and then falls onto the sieve.

[0031] Then, the external motor is started to drive the second rotating shaft 709 to rotate, and the second rotating shaft 709 drives the gear 708 to rotate, and then the gear 708 engages with the rack 710 to drive the filter 706 to move to the left. At this time, the filter 706 pulls the spring 707. When the gear 708 rotates to the position where the outer side is missing, the gear 708 no longer engages with the rack 710, and the retraction of the spring 707 drives the filter 706 to retract to the initial state. In this way, the large wood of the filter 706 is screened, and the qualified rice falls into the side box 712 and flows into the conveying cylinder 1 for transportation, while the broken rice falls from the holes in the filter 706 into the collection box 701 for collection.
