Description

Technical Field

[0002] The carbohydrates in rice are mainly starch, and the protein it contains is mainly glutenin, followed by rice gelatin and globulin. The biological value of its protein and the proportion of amino acid are higher than those of cereal crops such as wheat, barley, millet and corn. Rice is a finished product made from paddy rice after processes such as cleaning, husking, milling and finishing.

[0003] During the rice processing, the unprocessed rice needs to be taken out from the storage bin and then moved to the downward process for processing. Generally, the valve at the bottom of the storage bin is opened to allow the rice to fall into a collection box, but it is inconvenient to accurately control the amount of rice taken out. When a certain amount of rice is taken out, the valve is closed, and a portion of the rice will fall out during this process. When the rice is discharged, the discharge port is higher than the collection box, so the rice will collide with the collection box during the discharge process, causing the rice to splash everywhere, which will affect the accuracy of the discharge.

[0015] S1: First place the collection box under the mounting frame, and make the feed pipe inside the collection box;

[0016] S2: The distance between the first barrier bin and the second barrier bin is adjusted by operating the quantitative distance adjusting member, so as to control the amount of single material discharge;

[0017] S3: The second baffle plate blocks the rice inside the support frame by operating the alternating baffles, so that the first baffle plate loses its ability to block the rice above the second baffle bin, and the rice is discharged through the discharge pipe;

[0018] S4: The buffering feeding unit operates to change the position of the feeding pipe so that the feeding pipe rises slowly as the rice accumulates inside the collecting box. At the same time, the rice falling into the feeding pipe is buffered to prevent the rice discharged from the feeding pipe from having a large impact force and causing rice grains to splash.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By setting a quantitative distance adjustment member and rotating the adjusting screw, the first movable slider limited by the measuring limit rod is moved in the vertical direction along the adjusting screw by rotating the adjusting screw, so that the first bellows telescopic tube is extended or contracted, and the second bellows telescopic tube is also contracted with the movement of the second barrier chamber. Then, the amount of rice that can be placed in the first bellows telescopic tube is calculated according to the scale line on the measuring limit rod and the inner diameter of the first bellows telescopic tube, so as to accurately control the amount of single material discharge;

[0021] 2. By setting an alternating shielding member, the telescopic cylinder is started, and the extension of the telescopic cylinder causes the pull connecting rod to drive the first piston rod to move, so that the second baffle plate is moved to the top of the first corrugated telescopic tube. As the telescopic cylinder continues to extend, the aqueous solution inside the first piston sleeve enters the second piston sleeve through the connecting hose, so that the second piston rod moves relative to the second piston sleeve in a direction away from the second baffle bin, so that the first baffle plate loses its shielding of the bottom of the first corrugated telescopic tube. After the second baffle plate completely blocks the top of the first corrugated telescopic tube, the first baffle plate loses its shielding of the bottom of the first corrugated telescopic tube, preventing the rice inside the first corrugated telescopic tube from continuously falling into the first corrugated telescopic tube during the discharge process, thereby further improving the accuracy of material discharge;

[0022] 3. By setting a buffer discharge unit, when the telescopic cylinder is fully extended, the output end of the telescopic cylinder squeezes the push plate, so that the first contact piece contacts the second contact piece, so that the motor is powered on and operates. When the motor is operating, the second movable slider can move up along the reciprocating screw rod, so that the discharge pipe moves up as the rice accumulates in the collecting box. In this process, the rotating gear rotates along the positioning rack, and the stirring plate rotates with the rotation of the rotating shaft, so as to buffer the rice falling from the third corrugated telescopic tube into the discharge pipe, prevent the rice discharged through the discharge pipe from splashing due to the large impact force generated by the collection box when falling into the collection box, and also increase the fluidity of the rice in the discharge pipe.

[0036] In this embodiment: first, the collecting box is placed below the mounting frame plate 317, and the discharge pipe 306 is located inside the collecting box. Then, the distance between the first barrier bin 301 and the second barrier bin 302 is adjusted by operating the quantitative distance adjusting member to control the amount of single discharge. Then, the second barrier plate 328 is operated to block the rice inside the support frame 1 through the operation of the alternating shielding member, so that the first barrier plate 327 loses the shielding of the rice above the second barrier bin 302. At this time, the rice will be discharged through the discharge pipe 306. During this process, the buffer discharge unit operates to change the position of the discharge pipe 306 through the buffer discharge unit, so that the discharge pipe 306 slowly rises as the rice accumulates inside the collecting box. At the same time, the rice falling into the discharge pipe 306 is buffered to prevent the rice discharged from the discharge pipe 306 from having a large impact force and causing rice grains to splash.

[0037] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 The quantitative distance adjusting part includes a first corrugated telescopic tube 303 installed at the bottom of the first blocking chamber 301 and connected to the top of the second blocking chamber 302, a measuring limit rod 310 is installed on the inner side of the C-type side connecting frame 307, and the inner side of the C-type side connecting frame 307 is rotatably connected with an adjusting screw 312 arranged side by side with the measuring limit rod 310 through a bearing, and a first movable sliding block 311 movably sleeved on the measuring limit rod 310 and the adjusting screw 312 is installed on the outer wall of the second blocking chamber 302, and a second corrugated telescopic tube 304 connected to the top of the mounting frame plate 317 is installed at the bottom of the second blocking chamber 302.

[0038] In this embodiment, before the rice is unloaded, the adjusting screw rod 312 is rotated first, and the first movable slider 311 limited by the measuring limit rod 310 is moved vertically along the adjusting screw rod 312 by rotating the adjusting screw rod 312, so that the first bellows telescopic tube 303 is extended or contracted, and the second bellows telescopic tube 304 is also contracted with the movement of the second blocking chamber 302, and then the first bellows telescopic tube 303 is calculated according to the scale line on the measuring limit rod 310 and the inner diameter of the first bellows telescopic tube 303. The amount of rice that can be placed inside the contraction tube 303 can be used to accurately control the amount of material discharged at a single time. When the rice passes through the first barrier chamber 301 and falls into the first corrugated telescopic tube 303, the first barrier plate 327 will block the rice inside the first corrugated telescopic tube 303. Subsequently, the second barrier plate 328 can be used to block the top of the first barrier chamber 301 through alternating shielding parts, and at the same time, the first barrier plate 327 loses its shielding of the rice inside the first corrugated telescopic tube 303, thereby achieving accurate control of the amount of rice discharged.

[0039] Please refer to Figure 3 The first movable slider 311 is provided with a threaded hole matching the adjusting screw rod 312 and a through hole matching the measuring limit rod 310. The measuring limit rod 310 is provided with scale lines, and the zero scale line on the measuring limit rod 310 is aligned with the bottom of the first blocking chamber 301.

[0040] In this embodiment: by setting this structure, when the adjusting screw rod 312 rotates relative to the C-shaped side connecting frame 307, the first movable slider 311 drives the second blocking chamber 302 to move, so as to control the distance between the second blocking chamber 302 and the first blocking chamber 301, thereby adjusting the internal space of the first corrugated telescopic tube 303, and then calculating the amount of rice that can be stored in the first corrugated telescopic tube 303 according to the distance between the first blocking chamber 301 and the second blocking chamber 302.

[0041] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 The alternating shielding member includes a C-shaped side connecting frame 307 installed on the top of the first blocking chamber 301, a telescopic cylinder 309 is installed on the side of the C-shaped side connecting frame 307 away from the first blocking chamber 301, a first plug rod 323 extending to the outside of the first blocking chamber 301 is provided on the second blocking plate 328, an output end of the telescopic cylinder 309 is connected to a pull-in connecting rod 325 slidably connected to the first plug rod 323, a first piston sleeve 324 is installed at the bottom of the first plug rod 323, a first piston rod 320 extending to the outside of the first piston sleeve 324 and connected to the pull-in connecting rod 325 is installed inside the first piston sleeve 324, and the first piston rod 320 is connected to the outside of the first piston sleeve 324. 0 is provided with a first return spring 326 connected to the first piston sleeve 324, a second piston sleeve 331 is installed on the top of the second blocking chamber 302, a second piston rod 329 extending to the outside of the second piston sleeve 331 is inserted into the interior of the second piston sleeve 331, the second piston rod 329 is provided with a second return spring 330 connected to the second piston sleeve 331, a connecting hose 319 connected to the second piston sleeve 331 is provided at one end of the first piston sleeve 324 close to the first blocking chamber 301, and a second insertion rod 336 extending to the outside of the second blocking chamber 302 and connected to the second piston rod 329 is provided on the first blocking plate 327.

[0042] In this embodiment: when the rice fills the first bellows telescopic tube 303, the telescopic cylinder 309 is started, and the extension of the telescopic cylinder 309 causes the pull-in connecting rod 325 to drive the first piston rod 320 to move. At this time, the first piston rod 320 will cause the first piston sleeve 324 to move toward the first blocking chamber 301 through the first return spring 326, so that the second blocking plate 328 is moved to the top of the first bellows telescopic tube 303. As the telescopic cylinder 309 continues to extend, the second blocking plate 328 is blocked by the inner wall of the first blocking chamber 301, so that the first piston rod 320 can move relative to the first piston sleeve 324 with the push of the pull-in connecting rod 325, so that the aqueous solution inside the first piston sleeve 324 enters the second piston sleeve 331 through the connecting hose 319, so that the second piston rod 329 moves relative to the second piston sleeve 331 in a direction away from the second blocking chamber 302. The rice in the storage bin 2 is moved so that the first baffle plate 327 loses its covering on the bottom of the first bellows telescopic tube 303, so that the rice in the first bellows telescopic tube 303 falls into the second bellows telescopic tube 304 through the second baffle chamber 302, so that the second baffle plate 328 completely covers the top of the first bellows telescopic tube 303, and then the first baffle plate 327 loses its covering on the bottom of the first bellows telescopic tube 303, preventing the rice in the first bellows telescopic tube 303 from continuously falling into the first bellows telescopic tube 303 during the discharge process, thereby further improving the accuracy of material discharge. Similarly, when the telescopic cylinder 309 contracts, the first baffle plate 327 first blocks the bottom of the first bellows telescopic tube 303, and then the second baffle plate 328 loses its covering on the top of the first bellows telescopic tube 303, so that the rice in the storage bin 2 falls into the first bellows telescopic tube 303 through the first baffle chamber 301.

[0043] Please refer to Figure 5 , Figure 8 The first blocking chamber 301 and the second blocking chamber 302 are both provided with through holes with a diameter equal to the inner wall diameter of the first corrugated telescopic tube 303 , and the diameters of the first blocking plate 327 and the second blocking plate 328 are both equal to the inner wall diameter of the first corrugated telescopic tube 303 .

[0044] In this embodiment, this structure is provided to shield the bottom of the first bellows telescopic tube 303 when the first blocking plate 327 moves below the first bellows telescopic tube 303 .

[0045] Please refer to Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Fig. 9The buffer unloading unit includes a connecting bin 321 installed on the inner side of the C-shaped side connecting frame 307, a push plate 322 is slidably connected to the inner side of the connecting bin 321, a first contact piece 332 located on the inner side of the connecting bin 321 is provided on one side of the push plate 322, a second contact piece 333 at the same horizontal height as the first contact piece 332 is provided on the inner wall of the connecting bin 321, a third return spring 334 connected to the push plate 322 is provided on the inner wall of the connecting bin 321, a motor 318 is installed on the top of the mounting frame plate 317, and a reciprocating screw rod is connected to the output end of the motor 318 316, a third corrugated telescopic tube 305 connected to the top of the feed tube 306 is installed at the bottom of the mounting frame plate 317, a second movable slider 315 movably sleeved on the reciprocating screw 316 is installed on the outer wall of the feed tube 306, a rotating coupling 313 penetrating to the outside of the feed tube 306 is installed inside the feed tube 306, slave gears 314 are installed at both ends of the rotating coupling 313, a positioning rack 308 meshing with the slave gear 314 is installed on the inner side of the support frame 1, and a stirring plate 335 located on the inner side of the feed tube 306 is provided on the rotating coupling 313.

[0046] In this embodiment: when the telescopic cylinder 309 is fully extended, the output end of the telescopic cylinder 309 squeezes the push plate 322, so that the first contact piece 332 contacts the second contact piece 333, so that the motor 318 is powered on and operated. When the motor 318 is in operation, the second movable slider 315 can be moved up along the reciprocating screw rod 316, so that the discharge pipe 306 is moved up as the rice accumulates in the collection box. In this process, the rotating gear 314 rotates along the positioning rack 308, and the stirring plate 335 rotates with the rotation of the rotating shaft 313, so as to buffer the rice falling from the third corrugated telescopic tube 305 into the discharge pipe 306, prevent the rice discharged through the discharge pipe 306 from splashing due to the large impact force generated by the collection box when falling into the collection box, and also increase the fluidity of the rice in the discharge pipe 306.

[0047] Please refer to Figure 5 , Figure 6 , Fig. 9 The motor 318 is electrically connected to the second contact piece 333 through a wire, and the first contact piece 332 is electrically connected to the external power supply through a wire.

[0048] In this embodiment, by providing this structure, the motor 318 is operated when the second contact piece 333 contacts the first contact piece 332 , thereby controlling the operation timing of the motor 318 .

[0049] Please refer to Figure 7 The diameter of the stirring plate 335 is smaller than the top diameter of the discharge pipe 306 .

[0050] In this embodiment, this structure is provided to prevent the stirring plate 335 from rotating and causing the rice to get stuck between the stirring plate 335 and the discharge pipe 306, thereby achieving the goal of buffering the falling rice without affecting the discharge of the rice.

[0051] Please refer to Figure 7 , Fig. 9 The second movable slider 315 is provided with a crescent pin matching the reciprocating screw rod 316 , and the length of the positioning rack 308 is equal to the length of the third corrugated telescopic tube 305 .

[0052] In this embodiment: by setting this structure, the feed tube 306 moves along with the second movable slider 315 when the reciprocating screw 316 rotates, so as to adjust the distance between the feed tube 306 and the bottom of the collecting box, thereby preventing the accuracy of rice falling into the collecting box from being affected due to the long distance between the feed tube 306 and the bottom of the collecting box.

[0053] In combination with the above-mentioned precise feeding device for rice processing, a precise feeding method for rice processing is provided, which specifically comprises the following steps:

[0054] S1: First, place the collection box below the mounting frame 317, and make the feed pipe 306 located inside the collection box;

[0055] S2: Rotate the adjusting screw rod 312, and by rotating the adjusting screw rod 312, the first movable slider 311 limited by the measuring limit rod 310 moves in the vertical direction along the adjusting screw rod 312, so that the first bellows telescopic tube 303 is extended or contracted, and the second bellows telescopic tube 304 is also contracted with the movement of the second blocking chamber 302. Then, the amount of rice that can be placed in the first bellows telescopic tube 303 is calculated according to the scale line on the measuring limit rod 310 and the inner diameter of the first bellows telescopic tube 303, so as to accurately control the amount of single feeding. When the rice passes through the first blocking chamber 301 and falls into the first bellows telescopic tube 303, the first blocking plate 327 will block the rice in the first bellows telescopic tube 303;

[0056] S3: When the rice fills the first bellows telescopic tube 303, the telescopic cylinder 309 is started, and the extension of the telescopic cylinder 309 causes the pull rod 325 to drive the first piston rod 320 to move. At this time, the first piston rod 320 causes the first piston sleeve 324 to move toward the first blocking chamber 301 through the first return spring 326, so that the second blocking plate 328 is moved to the top of the first bellows telescopic tube 303. As the telescopic cylinder 309 continues to extend, the second blocking plate 328 is blocked by the inner wall of the first blocking chamber 301, so that the first piston rod 320 can move relative to the first piston sleeve 324 with the push of the pull rod 325, so that the aqueous solution inside the first piston sleeve 324 is passed through the connecting hose 3 19 enters the second piston sleeve 331, so that the second piston rod 329 moves relative to the second piston sleeve 331 in the direction away from the second blocking chamber 302, so that the first blocking plate 327 loses its shielding of the bottom of the first bellows telescopic tube 303, so that the rice inside the first bellows telescopic tube 303 passes through the second blocking chamber 302 and falls into the second bellows telescopic tube 304, so that after the second blocking plate 328 completely blocks the top of the first bellows telescopic tube 303, the first blocking plate 327 loses its shielding of the bottom of the first bellows telescopic tube 303, preventing the rice inside the first bellows telescopic tube 303 from continuously falling into the first bellows telescopic tube 303 during the discharge process, thereby further improving the accuracy of material discharge;

[0057] S4: When the telescopic cylinder 309 is fully extended, the output end of the telescopic cylinder 309 squeezes the push plate 322, so that the first contact piece 332 contacts the second contact piece 333, so that the motor 318 is powered on and operated. When the motor 318 is in operation, the second movable slider 315 can be moved up along the reciprocating screw rod 316, so that the discharge pipe 306 is moved up as the rice accumulates in the collection box. In this process, the rotating gear 314 rotates along the positioning rack 308, and the stirring plate 335 rotates with the rotation of the rotating shaft 313, so as to buffer the rice falling from the third corrugated telescopic tube 305 into the discharge pipe 306, prevent the rice discharged through the discharge pipe 306 from splashing due to the large impact force generated by the collection box when falling into the collection box, and also increase the fluidity of the rice in the discharge pipe 306.
