Description

Technical Field

[0001] The present invention relates to the technical field of nut processing, and more particularly to a feeding device and a feeding method for nut processing. Background Art

[0002] Nuts, as the name suggests, are a type of fruit with a hard, usually closed shell. They contain an edible part, primarily a seed or kernel. These seeds or kernels are not only delicious but also highly nutritious. They are rich in protein, fat, minerals, and various vitamins, and have numerous health benefits. For example, protein contributes to muscle growth and repair, while fat provides energy and maintains cell structure. Minerals such as magnesium and potassium are essential for bone health, while vitamins such as vitamin E and B vitamins contribute to antioxidant activity and metabolism. The design of the feeder is particularly critical in the processing of nuts. The feeder is the front end of the entire processing line, responsible for evenly and efficiently delivering the nuts to subsequent processing stages. A well-designed feeder can significantly improve processing efficiency, reduce breakage and waste during nut transportation, and thus ensure the quality of the final product.

[0003] According to the patent document: CN118618796A, a feeding device for nut processing and a feeding method thereof are disclosed, including a transmission mechanism, the transmission mechanism also includes a bottom plate, the top of the bottom plate is fixedly connected to a support frame 1, before using the device, the device is installed in the required position, the walnuts to be transmitted are placed in the feed pipe, and the power of the power motor is turned on, as the power motor drives the transmission column 2 to rotate, the transmission column 2 drives the transmission belt to rotate synchronously, so that the friction wheel installed on the outer wall of the transmission belt contacts the friction plate, and the friction force generated by the contact between the friction wheel and the friction plate will force the slide bar to move along the inner wall of the sliding track toward the mounting frame, forcing the rotating plate to form a shape as shown in FIG. Figure 5 The shape shown forms a receiving groove between the rotating plate and the conveyor belt. At this time, the walnuts on the inner wall of the feeding tube enter the receiving groove through the rotating baffle.

In addition, the kernels inside smaller nuts may not be fully mature, resulting in uneven kernel quality, which in turn affects the taste and nutritional value of the final product, affecting the quality and taste of the final product.

At the same time, the shaking of the screen 2424 can also effectively prevent the nuts from clogging the screen holes during the screening process, thereby improving the screening effect.

[0042] like Figure 10 As shown, the defective material conveying mechanism 4 includes a defective material conveying frame 41, and the left side of the rear side of the defective material conveying frame 41 is fixedly connected to the longitudinal conveying platform 47. The left side of the rear side of the defective material conveying frame 41 aligned with the longitudinal conveying platform 47 is hollowed out, and a conveying frame side groove 49 is opened on the front side of the defective material conveying frame 41. Both sides of the left side of the front side of the defective material conveying frame 41 are fixedly connected to hydraulic push rod connecting plates 43, and the front and rear sides of the inner sides of the two hydraulic push rod connecting plates 43 are fixedly connected to hydraulic push rod connecting blocks 44. The inner walls of the two hydraulic push rod connecting blocks 44 are fixedly connected to hydraulic push rods 45, and the rear ends of the hydraulic push rods 45 extend to the defective material conveying frame 4 1, the inner wall of the defective material conveying frame 41 is slidably connected with multiple material receiving boxes 46, and the right side of the inner wall of the conveying frame side groove 49 opened on the front side of the defective material conveying frame 41 is slidably connected with a push plate 410, the rear side of the push plate 410 extends to the inner wall of the defective material conveying frame 41 and the left side is attached to the right side of the rightmost material receiving box 46, the front side of the left side of the push plate 410 is fixedly connected with a spring 48, the left end of the spring 48 is fixedly connected to the right side of the right hydraulic push rod connecting plate 43, the leftmost material receiving box 46 is aligned with the longitudinal conveying platform 47 fixed on the left side of the rear side of the defective material conveying frame 41, and the front side of the leftmost material receiving box 46 is attached to the rear end of the hydraulic push rod 45;

[0043] The smaller nuts slide into the leftmost receiving box 46 through the defective material unloading inclined plate 23. When the leftmost receiving box 46 is full of smaller nuts, the hydraulic push rod 45 is started, pushing the leftmost receiving box 46 to slide backward until it is pushed to the top of the longitudinal conveying platform 47 and is conveyed to the next processing link through the longitudinal conveying platform 47. At the same time, the spring 48 is compressed to prepare for the reset of the push plate 410. When the leftmost receiving box 46 is pushed away, the spring 48 releases energy, pushing the push plate 410 to move to the left, and then pushing the remaining receiving boxes 46 to slide to the left in turn, so that the next receiving box 46 moves to the leftmost position and continues to receive the smaller nuts that have slipped through the defective material unloading inclined plate 23. In this way, the entire device can automatically and continuously complete the collection and conveying of smaller nuts, greatly improving the processing efficiency and degree of automation. The design of the entire defective material conveying mechanism 4 realizes the rapid collection and automatic box changing of smaller nuts, thereby improving the efficiency and degree of automation of nut processing.

[0044] In addition, the present invention also relates to a feeding device for nut processing and a feeding method thereof, comprising the following steps:

[0045] Step 1: Nuts are poured into the storage bin 2414 and enter the distributing and unloading assembly 2416 through the storage bin discharge funnel 2415. The motor 24169 is started, and the turntable 24170 and the second turntable 24172 rotate, driving the columnar transverse rod 24173, the roller 24174 and the baffle 24175 to rotate synchronously. The baffle 24175 intermittently guides the nuts to the discharge bin 24178 to prevent blockage and ensure that the nuts enter the next stage evenly and orderly.

[0046] Step 2: Nuts fall from the discharge bin 24178 onto the screening material discharge plate 2423. The fourth turntable 24215 is driven by the second crawler 24177, causing the second transmission shaft 24213, the transmission shaft 24211, and the third crawler 24212 to rotate. The third crawler 24212 drives the second columnar transverse rod 2429 and the diamond-shaped stop block 24216 to rotate. The stop block hits the disc 2428, causing the inverted L-shaped shaking block 2425 to shake inside the L-shaped side rod 2426. As a result, the screen 2424 shakes, screening the nuts. Small nuts pass through the screen 2424 and reach the residual material discharge plate 21. Large nuts remain on the screening material discharge plate 2423 and slide to the conveying mechanism 3 for processing.

[0047] Step 3: After screening, the smaller nuts slide along the defective material discharge inclined plate 23 to the leftmost receiving box 46 of the defective material conveying mechanism 4. When the receiving box 46 is full, the hydraulic push rod 45 is activated to push the receiving box 46 to slide backward to the longitudinal conveying platform 47, and then the nuts are conveyed to the next processing link through the longitudinal conveying platform 47.

[0048] Step 4: The spring 48 is compressed to prepare for the return of the push plate 410. When the leftmost receiving box 46 is pushed away, the spring 48 releases energy, pushing the push plate 410 to the left, and then pushing the remaining receiving boxes 46 to slide to the left in turn, so that the next receiving box 46 moves to the leftmost position to continue to receive the smaller nuts that have fallen. This process realizes the automatic collection and continuous transmission of smaller nuts, significantly improving processing efficiency and automation level.

[0049] The working principle of the present invention is as follows: when in use, nuts enter the unloading slant plate 24161 through the storage bin unloading funnel 2415, the motor 24169 is started, the output end of the motor 24169 drives the turntable 24170 to rotate, the turntable 24170 drives the second turntable 24172 to rotate through the crawler 24171, and then drives the columnar transverse rod 24173 to rotate, the rotation of the columnar transverse rod 24173 drives the roller 24174 and the baffle 24175 on the outer wall of the roller 24174 to rotate synchronously, and the rotation of the roller 24174 is realized. The rotating baffle 24175 intermittently discharges the falling nuts into the discharge bin 24178, and the nuts continue to be discharged from the bottom of the discharge bin 24178 to the top of the screening material discharge plate 2423. At this time, the two fourth turntables 24215 drive the two second transmission shafts 24213 to rotate synchronously through the transmission action of the second crawler 24177, and then drive the transmission shaft 24211 and the third crawler 24212 to rotate, so that the second columnar transverse rod 2429 rotates, and the second columnar transverse rod 2429 rotates. The two diamond-shaped blocks 24216 on the outer wall of 29 rotate synchronously and continuously resist the disc 2428, so that the disc 2428 drives the inverted L-shaped shaking block 2425 to shake back and forth on the inner wall of the L-shaped side rod 2426. The inverted L-shaped shaking block 2425 drives the screen 2424 to shake back and forth through the screening material discharge plate 2423, screening the nuts falling from the top of the screening material discharge plate 2423. The smaller nuts are screened to the bottom of the screen 2424 and fall on the residual material discharge plate 21 and pass through the residual material. The material discharge inclined plate 23 slides into the material receiving box 46 of the defective material conveying mechanism 4. When the material receiving box 46 is full of smaller nuts, the hydraulic push rod 45 is activated to push the material receiving box 46 to slide backward to the top of the longitudinal conveying platform 47, and is conveyed to the next processing link through the longitudinal conveying platform 47. The larger nuts continue to stay on the top of the screening material discharge plate 2423 and gradually slide to the transmission mechanism 3. Under the action of the transmission mechanism 3, the larger nuts are orderly conveyed to the next process for further processing.
