Technical Field

[0001] This utility model belongs to the technical field of fruit sorting equipment, specifically relating to a grading device for selecting Wogan oranges. Background Technology

[0002] Wogan mandarin oranges are a hybrid citrus variety that has become increasingly popular with consumers in recent years due to their thin peel, juiciness, and sweet-sour taste. Wuming District in Nanning City is a major production area for Wogan mandarin oranges, with a planting area of ​​460,000 mu (approximately 30,000 hectares) and an annual output of 1.5 million tons, accounting for more than 20% of the national planting area and output. Wogan mandarin oranges are graded mainly according to fruit diameter, commonly divided into three categories: large, medium, and small. Grading is done primarily by machine, supplemented by manual grading.

[0003] Chinese patent document CN209663758U discloses a grading machine for Wogan oranges used in agricultural production and processing. It includes a gradually opening multi-cavity spiral screen, a main shaft, a front support, a rear support, a lower opening guide tube, a buffer separator, and a speed-regulating motor. A long brush is added. The main shaft is connected to the inner side of the gradually opening multi-cavity spiral screen via a connecting rod. The front and rear supports are respectively connected to the two ends of the main shaft via bushings. The lower opening guide tube is connected to the front support and fits over the feed inlet end of the gradually opening multi-cavity spiral screen. The buffer separator and the long brush are both connected between the front and rear supports, with the long brush positioned above the buffer separator. The speed-regulating motor is connected to the main shaft at the rear support end via a belt. This invention provides a Wogan orange grading machine for agricultural production and processing that is simple to operate, produces good grading results, and requires fewer consumables.

[0004] In the above-mentioned patented technical solution, when the feed inlet of the gradually opening multi-cavity spiral screen tube rotates once, it will scoop the tangerines in the lower opening guide tube into the tube. The tangerines will roll to the appropriate-sized long opening and fall out, thus achieving grading. However, when this device is in use, the feed capacity of the feed inlet is limited, and the spiral screen tube used has the problem of a small screening capacity, which affects the grading efficiency. Utility Model Content

[0005] This invention provides a grading device for selecting Wogan oranges to solve the above-mentioned technical problems.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] A grading device for selecting Wogan oranges includes: a trough-shaped body, a drive unit and a receiving trough respectively disposed on the outside of the body, and a plurality of screening cylinders spaced apart inside the body; the drive unit can rotate the screening cylinders relative to the body via a transmission mechanism, the receiving trough is in communication with the inside of the screening cylinders, and the device further includes: a push plate disposed at the bottom of the trough of the body; a protective sleeve disposed on the push plate; the protective sleeve is located near the side of each screening cylinder away from the feeding end; there is a gap between the protective sleeve and the screening cylinder to avoid affecting the normal operation of the screening cylinders.

[0008] Furthermore, the sheath is made of a soft material and its length is greater than or equal to the length of the screening cylinder.

[0009] Furthermore, the pusher plate is inclined and is set from high to low along the direction of fruit movement, with an inclination angle of 10-20°.

[0010] Furthermore, the grading device also includes a collection trough located on the outside of the machine body and connected to the collection area formed by the last screening cylinder and the machine body.

[0011] Furthermore, the grading device also includes: a material guiding assembly, comprising: a material guiding trough, which is connected to the end of the machine body that is not equipped with a collection trough; a material guiding belt, which is disposed on the material guiding trough; a material guiding device; and a screening cylinder.

Detailed Implementation

[0027] To facilitate a better understanding of this utility model, the following examples are provided in conjunction with the accompanying drawings. These examples fall within the protection scope of this utility model, but do not limit the protection scope of this utility model.

[0028] Example 1

[0029] like Figures 1-4As shown, a grading device for selecting Wogan oranges includes: a trough-shaped machine body 1, a drive device 11 and a receiving trough 12 respectively disposed on the outside of the machine body 1, and a plurality of screening cylinders 2 spaced apart inside the machine body 1; the drive device 11 can rotate the screening cylinders 2 relative to the machine body 1 via a transmission mechanism, and the receiving trough 12 is in communication with the inside of the screening cylinders 2; the device also includes: a push plate 13 disposed at the bottom of the trough of the machine body 1; a protective sleeve 14 disposed on the push plate 13; the protective sleeve 14 is close to the side of each screening cylinder 2 away from the feeding end 01; there is a gap between the protective sleeve 14 and the screening cylinder 2 to avoid affecting the normal operation of the screening cylinder 2.

[0030] like Figures 1-2 As shown, the sheath 14 is made of soft material and its length is greater than or equal to the length of the screening cylinder 2.

[0031] like Figures 1-2 As shown, the push plate 13 is set at an angle, and is set from high to low along the direction of fruit movement, with an angle of 10-20°.

[0032] like Figures 1-2 As shown, the grading device also includes a collection tank 15, which is located on the outside of the machine body 1 and is connected to the collection area 16 formed by the last screening cylinder 2 and the machine body 1.

[0033] Several screening cylinders are provided, spaced apart along the direction in which the Wogan mandarins are transported. Several screening holes are distributed along the length and circumference of the screening cylinders, with the diameter of the screening holes increasing from small to large according to the direction of the fruit's movement. During the grading process, Wogan mandarins with a diameter smaller than the corresponding screening hole diameter will fall into the receiving trough under that screening cylinder; Wogan mandarins with a diameter larger than the corresponding screening hole diameter will be stuck on the screening hole and continue to rotate with the screening cylinder. They will then fall down under the action of the push plate and enter the next screening hole for grading.

[0034] The drive unit can be a motor, which drives the sieving cylinder to rotate through existing transmission methods such as belt drive. When the tangerines pass through the sieving cylinder, those with a diameter smaller than the diameter of the sieving holes on the sieving cylinder will enter the corresponding receiving trough, while those with a diameter larger than the diameter of the sieving holes will enter the next sieving cylinder for grading, thus realizing the grading operation.

[0035] The push plate is set with a certain degree of inclination, which makes it easy for the Wogan oranges falling on the push plate to roll from high to low. When the size of the screening hole of the screening cylinder is larger than the diameter of the Wogan orange, the fruit will fall into the corresponding receiving trough. The current machine body, screening cylinder, push plate and other parts are mostly made of stainless steel and other metal materials. During the screening process, scratches and collisions may cause damage to the peel. The protective sleeve covers the push plate to prevent the peel of the Wogan oranges from being scratched during the screening process, which would affect the appearance of the Wogan oranges.

[0036] Each set of push plates and each set of sieving cylinders are set slightly inclined along the direction of the fruit's movement; so that when the fruit falls from the previous sieving cylinder to the push plate, due to the height difference of the inclination, and under the weight of the fruit and the speed of its forward movement, it can easily enter the next sieving cylinder for grading.

[0037] In operation, first start the drive unit and pour the Wogan oranges to be sorted into the feeding end. The oranges roll onto the push plate of the initial section and then come into contact with the screening cylinder. When the fruit diameter is smaller than the screening hole, it will fall into the receiving trough, thus screening out the first type of Wogan oranges. Fruits with a diameter larger than the screening hole will continue to move forward as the screening hole rotates, and then fall off the first screening cylinder due to the action of the second push plate, and then roll to the second screening cylinder. When the fruit diameter is smaller than the screening hole at that point, the fruit will fall into the corresponding receiving trough, thus screening out the second type of Wogan oranges. When the fruit diameter is larger than the screening hole at that point, it will continue to move forward as the screening hole rotates, and then fall off the second screening cylinder due to the action of the third push plate, and then roll to the third screening cylinder. When the fruit diameter is smaller than the screening hole at that point, the fruit will fall into the corresponding receiving trough, thus screening out the third type of Wogan oranges. During screening, the appropriate number of screening cylinders and screening holes can be selected according to the defined fruit diameter range.

[0038] Example 2

[0039] like Figures 1-2 As shown, the grading device also includes: a material guiding assembly 3, comprising: a material guiding trough 31, which is connected to the end of the machine body 1 that is not equipped with a collection trough 15; a material guiding belt 32, which is disposed on the material guiding trough 31; and a material guiding device 33, which is disposed on the outside of the material guiding trough 31 and is connected to the material guiding belt 32 in a transmission manner; the end of the material guiding belt 32 is close to the screening cylinder 2.

[0040] like Figures 1-2 As shown, the guide belt 32 is inclined to the ground and connects to the machine body 1, with the end near the screening cylinder 2 at a lower position.

[0041] like Figures 1-2 As shown, the inclination angle between the guide belt 32 and the horizontal plane is 10-20°.

[0042] like Figures 1-2 As shown, the top of the guide belt 32 is provided with a protective layer 34; the protective layer 34 is made of soft material and its length and width are the same as the length of the guide belt 32.

[0043] The material guiding device can be a motor, which drives the material guiding belt to move through existing transmission methods such as belt drive.

[0044] In existing screening methods, Wogan oranges are directly poured into the feeding end, and the screening cylinder is used to screen the fruit. However, there is no external power to transport the Wogan oranges during this process. When the amount of fruit is large, they may stagnate on the push plate and affect the screening. Therefore, a material guiding component is installed. In use, the Wogan oranges to be sorted are first poured into the feeding end, and then the material guiding device is started to make the guide belt rotate, thereby moving the Wogan oranges towards the screening cylinder. Since the Wogan oranges on the screening cylinder have a certain speed, they can roll onto the screening cylinder, which facilitates the grading operation and avoids the accumulation of Wogan oranges on the push plate when there is a large amount of fruit, which would affect the grading operation.

[0045] Example 3

[0046] like Figures 1-3 As shown, the grading device also includes a controller 4, which is connected to the drive device 11 and the feeding device 33 for control.

[0047] The controller is connected to the drive unit and the material guide unit respectively, which makes it easy to control the start and stop of the drive unit and the material guide unit as needed during the grading operation.

[0048] like Figure 4 As shown, to prevent the graded tangerines from flowing out of the receiving trough during use, a rotating shaft is not suitable inside the screening cylinder to prevent the tangerines from being damaged by impact. Therefore, a slider 23 is installed on the end of the screening cylinder near the receiving trough. A groove is provided at the corresponding position of the machine body. The slider is engaged in the groove so that the screening cylinder can rotate stably when the drive device is running. Several sliders can be arranged at intervals. A soft, arc-shaped receiving member 21 can also be installed inside the screening cylinder to prevent the tangerines from falling to the bottom of the screening cylinder. The receiving member is inclined, with the end near the receiving trough in a low position and connected to the receiving trough. To ensure the stability of the receiving member, a support rod 22 is provided at its bottom. A groove is provided at the bottom of the screening cylinder corresponding to the support rod 22. The bottom of the support member is engaged in the groove so that the support rod does not move with the screening cylinder when the screening cylinder rotates. The support member can stably receive the graded tangerines and finally slide them into the receiving trough. Several support rods can be arranged at intervals along the length of the support member.
