Description

Technical Field

[0001] The utility model belongs to the technical field of walnut processing, and specifically relates to a feeding machine for walnut processing. Background Technique

[0002] Walnuts, together with almonds, cashews, and hazelnuts, are known as the world's four famous dried fruits. Walnut kernels are rich in nutrients, containing 15-20 grams of protein per 100 grams, relatively more fat, 10 grams of carbohydrates, and various trace elements and minerals such as calcium, phosphorus, and iron essential for the human body, as well as various vitamins such as carotene and riboflavin, which are beneficial to the human body and are one of the nut foods deeply loved by the common people; a feeding machine is required during the production and processing of walnuts.

[0003] After retrieval, CN213529569U discloses a feeding machine for walnut processing, which controls the sliding of a baffle through the meshing of a worm and a worm gear, so that the baffle can not only continuously slide to adjust the discharging rate of walnuts, but also adjust the opening size of the discharging chute, making it easy to control the discharging rate of the feeding machine.

[0004] The walnuts that do not pass through the sieve in this feeding machine will accumulate on the sieve.

A magnetic attraction plate is fixedly connected to the outer wall of the baffle. A magnet is fixedly connected to the outer wall of the box body.

[0010] As a preferred embodiment of the present invention, the uniform feeding mechanism includes a transmission belt rotatably connected to the output end of the motor. A rotating rod is rotatably connected to the end of the transmission belt away from the motor. A rotating push rod is fixedly connected to the outer wall of the rotating rod.

[0011] As a preferred embodiment of the present invention, the number of the screening plates is two. The screening plates are distributed symmetrically left and right inside the screening frame. The state of the screening plates is an inclined state and in a triangular shape.

[0012] As a preferred embodiment of the present invention, the bottom end of the extrusion block is provided with an inclined surface. The top end of the force-bearing rod is provided with an inclined surface. The inclined surfaces provided are in abutting and matching relationship.

[0017] In this utility model, the output end of the motor will drive the connecting rotating rod to rotate, thereby driving the extrusion block to rotate. During the rotation of the extrusion block, it will contact and exert an extrusion force on the stress rod. The stressed rod will drive the screening box to move to the left. When the screening box moves, it can drive the sliding rod and the connecting plate to move. When the connecting plate moves, it can drive the first spring to stretch. When the extrusion block continues to rotate and no longer contacts the stress rod, the first spring can rebound and reset to push the screening box to reset. By repeating this process, the screening box can be driven to move back and forth left and right, thus generating a vibration effect to screen the walnuts inside to select the appropriate size for conveying operations. When there are too many larger walnuts accumulated inside the screening box, the magnetic attraction plate can be directly pulled upward to drive the baffle plate to move upward, thereby opening the discharge through groove opened on the outer wall of the box until the magnetic attraction plate is moved to the bottom of the magnet for magnetic attraction fixation. In this way, the larger walnuts accumulated on the screening plate will roll to both sides along the inclination angle of the screening plate, thus discharging from the screening box. In this way, it is not necessary for workers to manually pick up the walnuts, greatly improving the discharge speed and further enhancing the efficiency of subsequent feeding work.

[0018] In this utility model, the output end of the motor drives the conveyor belt to rotate, thereby driving the rotating rod and the rotating push rod to rotate. During the rotation of the rotating push rod, it will contact and exert an extrusion force on the stress plate. The stressed plate will drive the sliding plate to move to the left. At the same time, during the movement of the sliding plate, the second spring will be stretched. At this time, the discharge hole opened at the top of the sliding plate will be exposed, and in this way, the walnuts will be evenly discharged through this discharge hole, preventing the discharge hole from being blocked due to a large number of walnuts discharging simultaneously. After one discharge, the sliding plate is driven to reset by the rebound of the second spring, thereby driving the discharge hole to move to the inner wall of the chute until the next push for discharging. By repeating this process, uniform discharging is achieved.

Specific implementation manners

[0027] To make the purposes, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0028] As Figures 1 to 5 shown, a feeding machine for walnut processing includes a box body 1, support legs 2 fixedly connected to the bottom end of the box body 1, a screening and discharging mechanism 31 is arranged inside the box body 1, a uniform feeding mechanism 32 is arranged below the screening and discharging mechanism 31. The screening and discharging mechanism 31 includes a first support plate 311 fixedly connected to the outer wall of the box body 1, a motor 312 is fixedly connected to the outer wall of the first support plate 311, the output end of the motor 312 is fixedly connected to a connecting rotating rod 313, the end of the connecting rotating rod 313 far from the motor 312 is fixedly connected to an extrusion block 314, a stress rod 315 movably penetrates through the outer wall of the box body 1, one end of the stress rod 315 is fixedly connected to a screening frame 316, a screening plate 317 is fixedly connected to the inner wall of the screening frame 316, a sliding rod 318 is fixedly connected to the end of the screening frame 316 far from the stress rod 315, a connecting plate 319 is fixedly connected to the end of the sliding rod 318 far from the screening frame 316, a first spring 3110 is fixedly connected to the outer wall of the end of the connecting plate 319 close to the sliding rod 318, the end of the first spring 3110 far from the connecting plate 319 is fixedly connected to the outer wall of the box body 1, a discharge through groove is formed in the outer wall of the box body 1, a limit chute 3111 is formed in the inner wall of the discharge through groove, a baffle 3112 is slidably connected to the inner wall of the limit chute 3111, a magnetic attraction plate 3113 is fixedly connected to the outer wall of the baffle 3112, and a magnet 3114 is fixedly connected to the outer wall of the box body 1.

[0029] Furthermore, the number of the screening plates 317 is two. The screening plates 317 are symmetrically distributed inside the screening frame 316 in a left-right symmetrical structure. The screening plates 317 are in an inclined state and in a triangular shape. In this way, the walnuts that have not passed through will accumulate at the bottom of the screening plates 317 through the inclination angle of the screening plates 317. In this way, when the baffle 3112 is directly opened later and combined with the vibration of the screening frame 316, automatic discharging can be achieved, without the need for subsequent manual picking by the staff, improving work efficiency.

[0030] Furthermore, the bottom end of the extrusion block 314 is provided with an inclined surface, and the top end of the force-bearing rod 315 is provided with an inclined surface. The inclined surfaces provided by both are fitted together. Through the inclined surfaces provided by both, the force-bearing rod 315 can be subjected to extrusion force, so as to ensure the left-right reciprocating movement of the screening frame 316 and thus generate a vibration effect to achieve the screening operation.

[0031] Furthermore, the outer wall of the screening frame 316 is fitted with the inner wall of the box body 1, so as to ensure the tight fit between the outer wall of the screening frame 316 and the inner wall of the box body 1, and thus ensure the stability of the screening frame 316 during the movement process.

[0032] The uniform feeding mechanism 32 includes a transmission belt 321 rotatably connected to the output end of the motor 312. One end of the transmission belt 321 away from the motor 312 is rotatably connected to a rotating rod 322. A rotating push rod 323 is fixedly connected to the outer wall of the rotating rod 322. A guide plate 324 is fixedly connected to the inner wall of the box body 1. A through chute is opened on the outer wall of one end of the guide plate 324 away from the inner wall of the box body 1. A sliding plate 325 is slidably connected to the inner wall of the through chute. A second spring 326 is fixedly connected to the outer wall of one end of the sliding plate 325 away from the through chute. One end of the second spring 326 away from the sliding plate 325 is fixedly connected to a second support plate 327. One end of the second support plate 327 away from the second spring 326 is fixedly connected to the outer wall of the box body 1. A force-bearing plate 328 is fixedly connected to the top end of the sliding plate 325.

[0033] Furthermore, the inner wall of the through chute opened on the outer wall of one end of the guide plate 324 is fitted with the outer wall of the sliding plate 325, so as to ensure the tight fit between the outer wall of the sliding plate 325 and the inner wall of the through chute, and thus ensure the stability of the sliding plate 325 during the movement process.

[0034] Furthermore, one side outer wall of the sliding plate 325 away from the through chute movably penetrates through the inner wall of the box body 1. A plurality of discharge holes are opened at the top end of the sliding plate 325. The discharge holes are evenly and equidistantly distributed at the top end of the sliding plate 325. Through the left-right reciprocating movement of the sliding plate 325, the discharge holes opened on the sliding plate 325 can achieve intermittent and continuous uniform feeding, preventing the blockage of the discharge chute caused by a large number of walnuts during the discharging process.

[0035] The implementation principle of a feeding machine for walnut processing in this embodiment is as follows: First, start the motor 312, and then put walnuts into the screening box 316 in the box body 1. The output end of the motor 312 will drive the connecting rotating rod 313 to rotate, thereby driving the extrusion block 314 to rotate. During the rotation of the extrusion block 314, it will contact and exert an extrusion effect on the stress rod 315. The stressed rod 315 subjected to extrusion will drive the screening box 316 to move to the left. When the screening box 316 moves, it can drive the sliding rod 318 and the connecting plate 319 to move. When the connecting plate 319 moves, it can drive the first spring 3110 to stretch. As the extrusion block 314 continues to rotate and no longer contacts the stress rod 315, the first spring 3110 at this time can rebound and reset to push the screening box 316 to reset. Repeating this way can drive the screening box 316 to move left and right reciprocally, thereby generating a vibration effect to screen out walnuts of appropriate size inside for conveying operation. When there are too many larger walnuts accumulated inside the screening box 316, the magnetic attraction plate 3113 can be directly pulled upward to drive the baffle 3112 to move upward, thereby opening the discharge through groove opened on the outer wall of the box body 1 until the magnetic attraction plate 3113 is moved to the bottom of the magnet 3114 for magnetic attraction and fixing. In this way, the larger walnuts accumulated on the screening plate 317 will roll to both sides through the inclination angle of the screening plate 317, thereby discharging from the screening box 316. In this way, it is not necessary for workers to manually pick up the walnuts, greatly improving the discharge speed and further improving the efficiency of the subsequent feeding work.

[0036] The walnuts after screening will fall into the guide plate 324, and the walnuts will be conveyed to the slide plate 325 through the guide plate 324. At this time, the output end of the motor 312 drives the transmission belt 321 to rotate, thereby driving the rotating rod 322 and the rotating push rod 323 to rotate. During the rotation of the rotating push rod 323, it will contact and exert an extrusion effect on the stress plate 328. The stressed plate 328 subjected to extrusion will drive the slide plate 325 to move to the left. At the same time, during the movement of the slide plate 325, the second spring 326 will be stretched. At this time, the discharge hole opened at the top of the slide plate 325 will leak, so that the walnuts will be evenly discharged through this discharge hole, preventing the discharge hole from being blocked due to a large number of walnuts discharging at the same time. After one discharge, the slide plate 325 is driven to reset by the rebound of the second spring 326, thereby driving the discharge hole to move to the inner wall of the chute until the next push for discharging. Repeating this way can achieve uniform discharging.
