Description

Technical Field

[0001] This invention relates to the field of jujube feeding technology, specifically to an automatic feeding device for jujube processing and sorting. Background Technology

[0002] Before processing and sorting, jujubes need to be fed to a certain height using an inclined belt conveyor with a feed hopper. Because of their smooth surface, jujubes are prone to rolling during the feeding process and may even roll off the conveyor belt. Existing technologies often use multiple equally spaced push plates on the conveyor belt to solve this problem.

[0003] However, in the actual feeding process, because the plastic baskets containing red dates are quite heavy, it is difficult to keep them at a fixed height for a long time. Workers usually use a burst of force to lift and flip the plastic baskets, and then pour the red dates into the feeding hopper. During this process, due to the height difference, the red dates collide with the inner wall of the feeding hopper. At the same time, due to the large amount of material fed at once, the red dates will not be discharged from the discharge port of the feeding hopper in time, but will be discharged in batches under the push of the belt conveyor. During this process, the red dates piled up in the middle and upper layers will have too many unnecessary collisions and frictions with the moving push plate and the surrounding red dates, which can easily damage their skin and reduce the yield rate. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic feeding device for processing and sorting jujubes, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic feeding device for processing and sorting jujubes, comprising a belt conveyor, wherein multiple push plates are equidistantly installed on the conveyor belt of the belt conveyor, and further comprising: A feeding assembly is installed on the belt conveyor. The feeding assembly includes a feeding bin fixedly installed on the belt conveyor. A guide plate is provided inside the feeding bin. A support seat is rotatably installed on the feeding bin. A pair of first vertical rods and a pair of second vertical rods are symmetrically arranged on the support seat. Limit rods are provided on the opposite sides of the first vertical rods and the second vertical rods.

[0006] Preferably, the guide plate is fixedly installed inside the feed hopper, and a baffle is fixedly installed on the feed hopper.

[0007] Preferably, the guide plate is rotatably disposed inside the feeding hopper, and the feeding hopper is provided with an adjustment component; The adjustment assembly includes a mounting rod fixedly installed inside the feed hopper, and a torsion spring is provided on the mounting rod. The two ends of the torsion spring abut against the opposite surfaces of the baffle and the guide plate, respectively.

[0008] Preferably, at least one buffer plate is installed on the guide plate, and the buffer plate is made of a flexible material.

[0009] Preferably, the number of buffer plates is set to two, and their cross-section is triangular, with the buffer plate closer to the baffle having a larger thickness.

[0010] Preferably, the support base has a placement groove for placing a plastic frame, the limiting rod on the first vertical rod has a first height relative to the groove surface of the placement groove, the limiting rod on the second vertical rod has a second height relative to the groove surface of the placement groove, and the first height is less than the second height.

[0011] Preferably, the support base is provided with an interceptor plate.

[0012] Preferably, the support base is provided with a support plate, and in the initial state, the support plate abuts against the baffle.

[0013] Preferably, a handle is fixedly connected to the support base.

[0014] Preferably, each of the limiting rods is rotatably connected to a rubber roller.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention adopts the technical means of combining the guide plate and the support seat. When it is necessary to feed the material, the plastic basket containing the red dates is placed on the support plate first, and then the plastic basket is rotated at a constant speed to pour the red dates into the feeding bin. With the inclined guide plate, the red dates are slowly fed into the conveyor belt of the belt conveyor, which can effectively reduce the probability of damage to the skin of the red dates during the feeding process.

[0016] (2) The present invention uses a combination of limiting rod and guide plate to reduce the height difference of the jujubes during the entire feeding process, reduce the kinetic energy when they collide with the feeding plate 202, and further reduce the probability of damage to the jujube skin.

[0017] (3) The present invention adopts the technical means of combining guide plate and buffer plate. By using the rotating guide plate and the buffer plate of different thickness, the red dates can be fed into the conveyor belt in batches, which can effectively reduce the wear frequency when the red dates are fed, improve the practicality of the device, and improve the uniformity of feeding, further improving the practicality of the device.

[0018] (4) The present invention adopts a rotating feeding method, which is easier and less labor-intensive than the traditional lifting and tilting method, and can reduce the workload of workers. Attached Figure Description

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1 Please see Figure 1-2 This embodiment provides a technical solution: an automatic feeding device for processing and sorting jujubes, including a belt conveyor 100, on which multiple push plates 101 are equidistantly installed, characterized in that it further includes: The feeding assembly 200 is mounted on the belt conveyor 100. The feeding assembly 200 includes a feed bin 201 fixedly mounted on the belt conveyor 100. A guide plate 202 is provided inside the feed bin 201. A support base 203 is rotatably mounted on the feed bin 201. A pair of first vertical rods 204 and a pair of second vertical rods 205 are symmetrically arranged on the support base 203. Limit rods 206 are provided on opposite sides of the first vertical rods 204 and second vertical rods 205. The guide plate 202 is fixedly installed in the feeding hopper 201. A baffle 207 is fixedly installed on the feeding hopper 201. A support plate 2032 is provided on the support base 203. In the initial state, the support plate 2032 abuts against the baffle 207. A handle 209 is fixedly connected to the support base 203. A rubber roller 2061 is rotatably connected to each limiting rod 206. A placement groove for placing a plastic frame is opened on the support base 203. The limiting rod 206 on the first vertical rod 204 has a first height relative to the groove surface of the placement groove. The limiting rod 206 on the second vertical rod 205 has a second height relative to the groove surface of the placement groove, and the first height is less than the second height.

[0023] The working principle of this embodiment is as follows: First, start the conveyor belt 100. Then, push the plastic basket containing red dates, opening upwards, into the placement slot on the upper side of the support base 203. The first vertical rod 204, in conjunction with the second vertical rod 205, limits the position of the plastic basket. Next, grasp the handle 209 and rotate it upwards at a uniform speed, causing the support base 203 and the plastic basket on it to rotate synchronously. This slowly pours the red dates from the plastic basket into the feeding hopper 201, ensuring even feeding and reducing unnecessary squeezing and friction between the red dates. The red dates fall onto the guide plate 202 and slide down the gap between the guide plate 202 and the feeding hopper 201 onto the conveyor belt. On the conveyor belt of the conveyor 100, as the plastic frame rotates to face downwards, because the first height is less than the second height, and the first height is set to be slightly greater than the height of the plastic basket, the frame near the second vertical rod 205 will detach from the placement groove under the action of gravity. This causes the entire plastic basket to rotate around the limiting rod 206 on the first vertical rod 204 as the fulcrum, until the frame on the other side of the plastic basket hits the limiting rod 206 on the second vertical rod 205, creating an instantaneous vibration. This vibration can shake off the dates stuck in the plastic basket, ensuring the smooth progress of the entire feeding process.

[0024] Optionally, a servo motor can be installed on the feed hopper to drive the support base 203 to rotate, further improving the stability of the feeding process.

[0025] Optionally, a rubber roller 2061 is rotatably connected to each limit rod 206. The rubber roller 2061 can be used to reduce friction when loading and unloading plastic crates, thereby improving the speed and convenience of loading and unloading.

[0026] Optionally, a support plate 2032 is provided on the support base 203. In the initial state, the support plate 2032 abuts against the baffle 207. The support plate 2032 can stabilize the support base in a horizontal position, facilitating the loading and unloading of the plastic basket.

[0027] Beneficial effects: This embodiment uses a combination of guide plate 202 and support base 203. When feeding is required, the plastic basket containing red dates is first placed on the support base 203, and then the plastic basket is rotated at a constant speed to pour the red dates into the feed hopper 201. With the inclined guide plate 202, the red dates are slowly fed onto the conveyor belt of the belt conveyor, which can effectively reduce the probability of damage to the skin of the red dates during the feeding process.

[0028] Example 2 Please see Figure 3-5 This embodiment provides another technical solution: an automatic feeding device for processing and sorting jujubes, including a belt conveyor 100, on which multiple push plates 101 are equidistantly installed, characterized in that it further includes: A feeding assembly 200 is mounted on a belt conveyor 100. The feeding assembly 200 includes a feeding bin 201 fixedly mounted on the belt conveyor 100. A guide plate 202 is disposed within the feeding bin 201. A support base 203 is rotatably mounted on the feeding bin 201. A pair of first vertical rods 204 and a pair of second vertical rods 205 are symmetrically arranged on the support base 203. Limit rods 206 are provided on opposite sides of the first vertical rods 204 and second vertical rods 205. The guide plate 202 is rotatably mounted within the feeding bin 201. An adjusting assembly 208 is disposed on the feeding bin 201. The adjusting assembly 208 includes a mounting rod 2081 fixedly mounted within the feeding bin 201. A torsion spring 2082 is disposed on the mounting rod 2081. The two ends of the torsion spring 2082 abut against the opposite surfaces of a baffle 207 and a guide plate 202, respectively. At least one buffer plate 2021 is installed on the support, and the buffer plate 2021 is made of flexible material. There are two buffer plates 2021, and their cross-sections are triangular. The buffer plate 2021 on the side closer to the baffle 207 is thicker. The support base 203 has a placement groove for placing a plastic frame. The limiting rod 206 on the first vertical rod 204 has a first height relative to the groove surface of the placement groove, and the limiting rod 206 on the second vertical rod 205 has a second height relative to the groove surface of the placement groove. The first height is limited to the second height. An intercepting plate 2031 is provided on the support base 203. A support plate 2032 is provided on the support base 203. In the initial state, the support plate 2032 abuts against the baffle 207. A handle 209 is fixedly connected to the support base 203. A rubber roller 2061 is rotatably connected to each limiting rod 206.

[0029] The working principle of this embodiment is as follows: First, start the conveyor belt 100. Then, push the plastic basket containing red dates, opening upwards, into the placement slot on the upper side of the support base 203. The first vertical rod 204, in conjunction with the second vertical rod 205, limits the position of the plastic basket. Next, grasp the handle 209 and rotate it upwards at a uniform speed, causing the support base 203 and the plastic basket on it to rotate synchronously. This slowly pours the red dates from the plastic basket into the feeding hopper 201, ensuring even feeding and reducing unnecessary squeezing and friction between the red dates. The red dates fall onto the guide plate 202 and slide down the gap between the guide plate 202 and the feeding hopper 201 onto the conveyor belt. On the conveyor belt of the conveyor 100, as the plastic frame rotates to face downwards, because the first height is less than the second height, and the first height is set to be slightly greater than the height of the plastic basket, the frame near the second vertical rod 205 will detach from the placement groove under the action of gravity. This causes the entire plastic basket to rotate around the limiting rod 206 on the first vertical rod 204 as the fulcrum, until the frame on the other side of the plastic basket hits the limiting rod 206 on the second vertical rod 205, creating an instantaneous vibration. This vibration can shake off the dates stuck in the plastic basket, ensuring the smooth progress of the entire feeding process.

[0030] Meanwhile, during the jujube falling process, the guide plate 202, being a rotating device, works in conjunction with the torsion spring 2082 to provide some protection. The initial tilt angle of the guide plate 202 is relatively small, reducing the height difference between the falling jujubes and minimizing the probability of damage. As the plastic basket rotates, the second vertical rod 205 contacts and presses against the guide plate 202, causing it to rotate. The torsion spring 2082 deforms, providing space for more jujubes to enter. Simultaneously, as the tilt angle increases, the jujubes remaining on the guide plate 202 gradually roll off and fall evenly onto the conveyor belt, effectively preventing unnecessary damage caused by jujube accumulation. After the plastic basket is emptied, the support base 203 rotates in the opposite direction, resetting the plastic basket, which is then removed. The guide plate 202 also resets under the elastic force of the torsion spring 2082, allowing the next basket of jujubes to be loaded. This cycle repeats continuously, completing the loading process.

[0031] Optionally, two buffer plates 2021 are provided, with a triangular cross-section. The buffer plate 2021 closer to the baffle 207 is thicker. This design provides better protection for the dates. The difference in thickness between the two buffer plates allows the dates piled on them to be fed in batches as the guide plate 202 rotates. The buffer plate 2021 further from the baffle 207, being thinner, receives priority feeding of dates as the guide plate 202 rotates. The thicker buffer plate 2021 slows down the feeding process, further reducing friction between the dates and between the dates and the baffle 207. This batch feeding also improves the uniformity of the feeding, preventing excessive accumulation of dates on a single baffle 207 and enhancing the practicality of the device.

[0032] Optionally, a rubber roller 2061 is rotatably connected to each limit rod 206. The rubber roller 2061 can be used to reduce friction when loading and unloading plastic crates, thereby improving the speed and convenience of loading and unloading.

[0033] Optionally, the buffer plate 2021 can be made of rubber and other abrasion-resistant flexible materials to further enhance its protective function.

[0034] Beneficial effects: This embodiment employs a combination of a guide plate 202 and a support base 203. When feeding is required, the plastic basket containing red dates is first placed on the support base 203, and then the basket is rotated at a uniform speed to pour the red dates into the feed hopper 201. With the inclined guide plate 202, the red dates are slowly fed onto the conveyor belt of the belt conveyor, which can effectively reduce the probability of damage to the skin of the red dates during the feeding process. Furthermore, with the limit rod 206 pushing the guide plate 202 to rotate, the falling height of the red dates can be reduced throughout the feeding process, further reducing the probability of damage to the skin of the red dates. Moreover, with the use of buffer plates 2021 of different thicknesses, the red dates are fed onto the conveyor belt in batches, which can effectively reduce the wear frequency of the red dates during feeding and improve the practicality of this device.
