Technical Field

[0001] This utility model relates to the technical field of fruit grading and sorting machines, and more specifically, to a damage-resistant fruit grading and sorting machine. Background Technology

[0002] The damage-resistant fruit grading and sorting machine is a device used to grade and sort fruits while effectively preventing damage to the fruits. It uses soft conveyor belts, buffer devices, rubber pads and other components to reduce collisions and friction between the fruits and the equipment, reduce the risk of fruit damage, and treat the fruits gently to avoid damage caused by rough operation.

[0003] Utility model patent CN222535541U discloses a fruit sorting device. This device includes a support column, a first housing fixedly connected to the upper surface of the support column, a feed inlet on one outer surface of the first housing, four discharge outlets on the upper surface of the first housing, a guide plate fixedly connected to the upper surface of the first housing, guide tubes fixedly connected to the inner surfaces of the four discharge outlets, a guiding mechanism fixedly connected to the lower end of each guide tube, and a transmission mechanism fixedly connected to the lower part of the first housing. Through the arrangement of the guiding mechanism and the transmission mechanism, fully automatic fruit sorting is achieved, enabling multi-stage sorting and improving efficiency.

[0004] Although the fruit sorting device is convenient for multi-stage fruit sorting and has high efficiency, it still has the following problems in actual use: the guide tube is relatively high, and the sorted fruits are easily damaged as they flow through the guide tube to the guide plate. Therefore, we propose a damage-resistant fruit grading and sorting machine. Utility Model Content

[0005] In view of the aforementioned defects or shortcomings of existing technologies that make fruits easily damaged by drops, it is desirable to provide a fruit grading and sorting machine that prevents damage.

[0006] In a first aspect, this application provides a damage-resistant fruit grading and sorting machine, comprising a machine body. Inside the machine body, near the front feed hopper, an inclined feed belt is fixedly installed. From front to back, a plurality of fruit screening components are arranged sequentially near the higher end of the feed belt. Each fruit screening component includes a fruit screening belt in the shape of an inverted trapezoidal ring. A plurality of screening slots are evenly spaced on the fruit screening belt. A collection box assembly is installed on the inner side of each fruit screening belt. The collection box assembly includes a box body installed on the inner side wall of the machine body. A conveyor belt for outputting fruit is provided at the bottom of the box body. An outlet extending beyond the side wall of the machine body is fixedly installed on one side of the outer wall of the box body. A gear that meshes with the conveyor belt is provided on the outer side wall of the box body away from the outlet. A plurality of gears are coaxially connected through the same shaft. The machine body also has a transmission group for simultaneously driving the feed belt and the plurality of fruit screening belts to rotate. The transmission group includes a plurality of transmission belts and a transmission motor fixedly installed on the outer side wall of the machine body.

[0007] According to the technical solution provided in the embodiments of this application, the inclination angle of the feed belt is 15°-30°, and a number of equally spaced pallets are fixed on the feed belt. The feed belt has a first transmission roller that is rotatably inserted between two opposite side walls of the machine body at both ends. One of the first transmission rollers is coaxially connected to a drive wheel at the end near the drive motor. The output shaft of the drive motor and the drive wheel are coaxially connected.

[0008] In this setup, the feed belt drives the fruit upwards through drive wheels and rollers to enter the fruit screening assembly for screening, and the tray ensures that the fruit will not roll off.

[0009] According to the technical solution provided in the embodiments of this application, each of the fruit screening belts is provided with at least four second transmission rollers. The second transmission rollers are rotatably inserted between two opposite side walls of the machine body. The two diagonally opposite second transmission rollers in each of the fruit screening belts are coaxially connected to a transmission wheel at the end near the transmission motor.

[0010] In this setup, power is provided by a drive motor, which then drives the entire transmission assembly through a drive wheel connection.

[0011] According to the technical solution provided in the embodiments of this application, the drive wheel is connected to the frontmost drive wheel inside the fruit screening belt via a drive belt, and the two drive wheels that are close to each other at an angle inside the two adjacent fruit screening belts are connected via a drive belt.

[0012] In this setup, the transmission connection between the drive wheels drives the operation of the entire transmission assembly without affecting the transmission of the fruit on the feed belt.

[0013] According to the technical solution provided in the embodiments of this application, the width of the sieve grooves on the sieve belts distributed from front to back increases sequentially;

[0014] In this setup, the trough width increases sequentially to ensure that fruits of different sizes enter different boxes, achieving the purpose of multi-level grading and screening.

[0015] According to the technical solution provided in the embodiments of this application, anti-pinch rollers are provided between the feeding belt and the foremost screening belt and between each two adjacent screening belts, and the apex of the anti-pinch roller and the top surface of the screening belt are located on the same horizontal plane. The anti-pinch roller is rotatably inserted between two opposite side walls of the machine body.

[0016] In this setup, the anti-pinch roller, with its apex and the top surface of the screening belt on the same horizontal plane, ensures that the fruit will not get stuck between the screening components and will not hinder the transfer of the fruit.

[0017] According to the technical solution provided in the embodiments of this application, the size of the box is smaller than the inner size of the fruit screening belt, and the width of the top opening of the box is adapted to the distance between the two second transmission rollers at the two ends of the inner top of the fruit screening belt.

[0018] In this setup, the box is fixed inside the fruit screening assembly and will not affect the linkage effect of the transmission group with the device.

[0019] According to the technical solution provided in the embodiments of this application, the inner side wall of the box is covered with a soft rubber pad of a suitable size, a number of equally spaced rubber blocks are fixed on the conveyor belt, and an output shaft and a conveyor motor coaxially connected to a shaft connecting a number of gears are fixedly installed on the outer side wall of the machine body.

[0020] In this setup, soft rubber pads and rubber blocks ensure that the fruit will not be damaged after falling from the sieve into the box.

[0021] According to the technical solution provided in the embodiments of this application, a guide plate with an inclined arrangement and baffles installed on both sides is fixedly connected to the side of the discharge port away from the box body, and the angle between the guide plate and the horizontal ground is 30°-45°.

[0022] In this setup, a guide plate with a baffle ensures that the fruit does not fall directly from the discharge port to the ground and be damaged.

[0023] In summary, this technical solution specifically discloses a damage-preventing fruit grading and sorting machine, which includes a feeding belt, a fruit screening belt, a fruit screening trough, a collection box assembly, a conveyor belt, a guide plate, and a transmission group. After the fruit enters the device through the feeding hopper, it is first conveyed to the top surface of multiple fruit screening belts by the feeding belt to achieve automatic fruit feeding. The feeding belt and the fruit screening belt are driven by a set of motors through the transmission group to achieve multi-functional linkage, saving costs. The fruit enters the corresponding box through the fruit screening trough with progressively increasing trough width on the top surface of the fruit screening belt to achieve multi-stage grading. The fruit entering the box is protected from damage by soft rubber pads and rubber blocks. Finally, the fruit in the box is automatically and without damage discharged by the conveyor belt under the guidance of the guide plate. Attached Figure Description

[0038] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] Please see Figures 1-6 The damage-resistant fruit grading and sorting machine includes a body 1. Inside the body 1, near the front feed hopper 11, an inclined feed belt 2 is fixedly installed. From front to back, several fruit screening components 3 are arranged sequentially near the higher end of the feed belt 2. Each fruit screening component 3 includes an inverted trapezoidal ring-shaped fruit screening belt 31 with several equally spaced screening grooves 32. A collection box assembly 4 is installed inside each fruit screening belt 31. The collection box assembly 4 includes a box 40 installed on the inner wall of the body 1, with a bottom section... There is a conveyor belt 42 for outputting the fruit. A discharge port 46 extending out of the side wall of the machine body 1 is fixedly installed on one side outer wall of the box body 40. A gear 44 that meshes with the conveyor belt 42 is provided on the side wall of the box body 40 away from the discharge port 46. Several gears 44 are coaxially connected through the same shaft. A transmission group 6 for simultaneously driving the feed belt 2 and several fruit screening belts 31 to rotate is also installed inside the machine body 1. The transmission group 6 includes several transmission belts 64 and a transmission motor 61 fixedly installed on the outer wall of the machine body 1.

[0041] Furthermore, such as Figure 3 As shown, the width of the sieve grooves 32 on several fruit screening belts 31 distributed from front to back increases sequentially. The sieve grooves 32 with the width increasing sequentially from near the feed belt 2 ensure that larger fruits will not enter the box 40 that collects smaller fruits in front, thus playing a role in grading and screening.

[0042] Furthermore, such as Figure 2 As shown, anti-pinch rollers 5 are provided between the feeding belt 2 and the frontmost fruit screening belt 31, as well as between every two adjacent fruit screening belts 31. The apex of the anti-pinch roller 5 and the top surface of the fruit screening belt 31 are on the same horizontal plane. The anti-pinch roller 5 is rotatably inserted between the two opposite side walls of the machine body 1 to ensure that the anti-pinch roller 5 will not affect the transmission of the fruit on the feeding belt 2 and the fruit screening belt 31, and can prevent the fruit from getting stuck in the gap or falling out of the gap.

[0043] In this example, such as Figure 2As shown, the preferred inclination angle of the feed belt 2 is 15°. Several equidistantly arranged trays 21 are fixed on the feed belt 2. Both ends of the feed belt 2 are equipped with first transmission rollers 22 that are rotatably inserted between the two opposite side walls of the machine body 1. One of the first transmission rollers 22 is coaxially connected to a drive wheel 63 at the end near the drive motor 61. The output shaft of the drive motor 61 and the drive wheel 62 are coaxially connected. The 15° feed belt 2 drives the fruit into the subsequent grading and screening process. The trays 21 ensure that the fruit will not roll off the feed belt. The first transmission rollers 22 fix the feed belt 2 inside the machine body 1.

[0044] Furthermore, such as Figure 2 As shown, each screening belt 31 is equipped with at least four second transmission rollers 33. The second transmission rollers 33 are rotatably inserted between two opposite side walls of the machine body 1. Two of the second transmission rollers 33 at opposite corners in each screening belt 31 are coaxially connected to a transmission wheel 62 at the end near the drive motor 61. The entire device is driven by the drive motor 61 to drive the transmission wheel 62, the driving wheel 63 and the driven wheel 66. The second transmission rollers 33 play a role in stabilizing the entire transmission device.

[0045] Furthermore, such as Figure 3 As shown, the drive wheel 63 is connected to the front drive wheel 62 inside the frontmost screening belt 31 via a drive belt 64. The two drive wheels 62 that are close to each other at an angle inside the two adjacent screening belts 31 are connected via a drive belt 64. The drive motor 61 drives the feed belt 2 and the drive belt 64 simultaneously through the drive wheel 63 and the drive wheel 62, and the two do not interfere with each other.

[0046] In this example, such as Figure 4 As shown, the size of the box 40 is smaller than the inner size of the fruit screening belt 31, and the width of the top opening of the box 40 is matched with the distance between the two second transmission rollers 33 at the two ends of the inner top of the fruit screening belt 31. The box 40 is fixed in the fruit screening assembly 3 to prevent the fruit from falling due to instability of the box 40, and it will not affect the transmission of the transmission group 6 to the overall device.

[0047] Furthermore, such as Figure 4 As shown, the inner wall of the box 40 is covered with a soft rubber pad 41 of a suitable size, and a number of rubber blocks 43 arranged at equal intervals are fixed on the conveyor belt 42. The outer wall of the machine body 1 is fixedly installed with an output shaft and a conveyor motor 45 coaxially connected to a shaft that connects to a number of gears 44. The soft rubber pad 41 and the rubber blocks 43 ensure that the fruit will not be broken or damaged during the screening process.

[0048] It is worth mentioning that, such as Figure 1As shown, a guide plate 47 with an inclined setting and baffles installed on both sides is fixedly connected to the side of the discharge port 46 away from the box body 40. The angle between the guide plate 47 and the horizontal ground is preferably 30°. The guide plate 47 plays the role of guiding the fruit to roll out of the device and can prevent the fruit from falling directly from the discharge port 46 and causing damage.

[0049] Finally, it should be noted that the material transfer motor 45, transmission motor 61, and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0050] Working principle: When using the damage-resistant fruit grading and sorting machine of this embodiment, first connect the drive motor 61 and the material conveying motor 45 to the external power supply, and guide the fruit from the feed hopper 11 into the machine body 1 so that it rolls onto the feed belt 2. The fruit will be transmitted to the top surface of the screening belt 31 under the transmission of the transmission group 6. Then, the fruit will be screened by multiple screening belts 31 with progressively increasing width of the screening groove 32 and enter the corresponding box 40 respectively. Finally, the fruit in the box 40 will be discharged through the guide plate 47 under the drive of the material conveying belt 42.
