[0045] Reference Figures 1 to 4 , which is the first embodiment of the utility model, proposes a device for screening agricultural products, characterized in that it includes a frame 1, the frame 1 has a first mounting portion 101; a plurality of blanking plates 2, which are arranged on the frame 1 and are used to receive agricultural products of different sizes after screening; a rotating roller 3 has a plurality of receiving portions 301, the receiving portions 301 are evenly distributed along the axis of the rotating roller 3, the number of the rotating rollers 3 is consistent with the number of the blanking plates 2, the rotating roller 3 is rotatably arranged on the first mounting portion 101, and the receiving portions 301 are used to receive agricultural products after passing through the blanking plates 2; a plurality of casters 17 are arranged on the lower surface of the frame 1.
[0046] In this embodiment, the frame 1 is made of high-strength aluminum alloy, making it not only durable but also lightweight and easy to move. The first mounting portion 101 is secured to the frame 1 via precision bolts, ensuring a secure connection. Four blanking plates 2 are arranged at the same angle, allowing adjustment based on the characteristics of the agricultural product and its drop speed. The blanking plates 2 are attached to the frame 1 using a combination of slots and screws, making them easy to remove and clean. The rotating roller 3 is made of stainless steel, offering excellent corrosion and wear resistance. The receiving portion 301 is welded to the rotating roller 3, ensuring stable reception of agricultural products. Agricultural products include, but are not limited to, apples, oranges, and pears. The rotating roller 3 is mounted on the first mounting portion 101 via high-precision ball bearings, ensuring smooth rotation and low friction. The casters 17 are universal casters with brakes, with four evenly distributed at the four corners of the bottom of the frame 1. The caster 17's hub is made of high-strength engineering plastic, and the tire is made of wear-resistant rubber, adaptable to various floor conditions.
[0047] The advantage is that the frame 1 provides solid support for the entire device, ensuring that it will not shake or deform during movement and operation. The cooperation of the blanking plate 2 and the rotating roller 3 allows the screened agricultural products to slide to the corresponding positions in an orderly manner according to different sizes for collection. The setting of the casters 17 makes the entire device extremely maneuverable. At the agricultural product picking site, the device can be easily moved to the appropriate place according to the location and needs of the pickers. For example, in an orchard, when the pickers are picking in different fruit tree areas, the device can follow the movement at any time, and the picked agricultural products can be immediately screened and processed, which greatly improves work efficiency. At the same time, the brake function of the casters 17 can fix the device after it reaches the designated position to ensure the stability of the device during operation.
[0048] Furthermore, the supporting portion 301 has an abutting portion 3011 and also includes an abutting rod 4, one end of which is rotatably set on the frame 1 and is located between the axis of the blanking plate 2 and the rotating roller 3, and the other end of the abutting rod 4 abuts against the abutting portion 3011; the two ends of the first elastic member 5 are respectively connected to the abutting rod 4 and the frame 1, for providing a force for the other end of the abutting rod 4 to approach the blanking plate 2. After the rotating roller 3 rotates, the abutting portion 3011 abuts against or releases the abutment with the abutting rod 4.
[0049] In this embodiment, the abutment portion 3011 is a raised rubber block on the rotating roller 3. It has a certain degree of elasticity and can reduce the impact force when it contacts the abutment rod 4. The abutment rod 4 is a long rod made of solid steel. One end is mounted on the frame 1 via a flexible rotating shaft, allowing free rotation. The other end is designed into an arc shape to better fit the abutment portion 3011. The first elastic member 5 is a tension spring, with its two ends connected to the abutment rod 4 and the frame 1 respectively via hooks. When the rotating roller 3 rotates, the abutment portion 3011 and the abutment rod 4 constantly contact and separate. The spring will expand and contract according to the rotation, providing a corresponding elastic force.
[0050] The advantage is that during movement, the contact rod 4 and the first elastic member 5 can act as a buffer against uneven or vibrating surfaces, ensuring that the rotation of the rotating roller 3 is not excessively disturbed by external factors. Furthermore, during the screening of agricultural products, this structure can set the weight of the agricultural products required for a single flip, and flipping will occur once the weight reaches a certain level.
[0051] Furthermore, the first mounting portion 101 has a ratchet 6 and also includes a pawl 7, one end of the pawl 7 is rotatably set at one end of the rotating roller 3, and the other end of the pawl 7 is engaged with the ratchet 6; the two ends of the second elastic member 8 are respectively connected to the pawl 7 and the rotating roller 3, for providing a force for the other end of the pawl 7 to approach the ratchet 6.
[0052] In this embodiment, the ratchet teeth 6 on the first mounting portion 101 are precision-machined metal teeth, evenly distributed and angled to ensure tight engagement with the pawl 7. The pawl 7 is made of high-strength alloy steel, one end of which is mounted to the end of the rotating roller 3 via a reliable pin, allowing for flexible rotation. The second elastic member 8 is a torsion spring, mounted on the rotating shaft between the pawl 7 and the rotating roller 3. The torsional force of the spring ensures that the pawl 7 always tends to engage with the ratchet teeth 6.
[0053] The advantage is that when the device is moved or shaken by external factors, the coordination between the pawl 7 and the ratchet 6 prevents the rotating roller 3 from accidentally reversing, ensuring stable operation of the device under all circumstances. Especially during frequent movement and repositioning of the device, there is no need to worry about the position of the rotating roller 3 shifting, thus ensuring accurate and stable screening. Furthermore, this structure eliminates the need to readjust the position of the rotating roller 3 after moving to a different work location, allowing immediate resumption of work, significantly improving work efficiency.
[0054] Furthermore, it also includes a feeding device 9, which is arranged on the frame 1; a screening device 10 is arranged on the frame 1, located at the rear section of the feeding device 9, and is used to screen the agricultural products after passing through the feeding device 9.
[0055] In this embodiment, the feeding device 9 utilizes a motorized conveyor belt made of wear-resistant rubber with anti-slip ribs to prevent agricultural products from slipping during loading. The motor is a highly efficient, energy-saving DC motor, which drives the conveyor belt via a chain drive. The screening device 10, located at the rear end of the feeding device 9, consists of multiple stainless steel screens of varying apertures. These screens are mounted on the frame 1 via slots and can be replaced according to the specific agricultural product screening requirements. The screens are connected by damping springs to reduce the transmission of vibrations during the screening process to the frame 1.
[0056] The advantage is that the automatic loading function of the loading device 9, combined with the device's mobility, allows loading and screening of agricultural products anytime and anywhere at the harvesting site. For example, in the fields, pickers can place agricultural products directly on the conveyor belt, and the device can automatically complete the subsequent screening work, eliminating the need for manual transportation to a fixed screening location. The screening device 10 can accurately classify agricultural products according to size and can quickly adapt to the screening needs of different types of agricultural products when moved to different areas for operation, thereby improving work flexibility and efficiency.
[0057] Furthermore, it also includes a cleaning device 11, which is arranged on the feeding device 9; a drying device 12 is arranged on the feeding device 9, located at the rear section of the cleaning device 11, for drying the agricultural products after passing through the cleaning device 11.
[0058] In this embodiment, the cleaning device 11 consists of multiple high-pressure nozzles evenly distributed above the feeding device 9 and connected to a water source via a water pipe. The nozzles can adjust the angle and pressure of the water spray to meet the cleaning requirements of different agricultural products. The drying device 12 consists of multiple hot air blowers mounted on a bracket above the feeding device 9. The hot air blowers blow hot air evenly toward the agricultural products through air ducts. The temperature of the hot air blowers can be adjusted according to the characteristics of the agricultural products.
[0059] The advantage is that the combination of the cleaning device 11 and the drying device 12 allows the agricultural products to be cleaned and dried immediately after screening, preserving their freshness and quality. Furthermore, because the device is mobile, these processes can be completed at the harvest site, reducing the risk of secondary contamination and spoilage during transportation. For example, after harvesting, vegetables can be cleaned and dried directly in the field before being packaged and stored, significantly increasing the added value and market competitiveness of the agricultural products.
[0060] Furthermore, the feeding device 9 has a first angle with the ground, the first angle is α, and also includes a feeding frame 13, which is arranged at the end of the feeding device 9 away from the screening device 10; the transition plate 14 is arranged on the frame 1, located between the feeding device 9 and the screening device 10.
[0061] In this embodiment, the feeding device 9 forms a first angle α with the ground. This angle, determined through extensive testing and optimization, ensures smooth movement of agricultural products under gravity while preventing them from sliding down too quickly and potentially being damaged. The feeding frame 13 is welded from stainless steel and has a trumpet-shaped design, facilitating the loading of agricultural products. The transition plate 14, a smooth aluminum alloy plate, is installed at an angle between the feeding device 9 and the screening device 10 and bolted to the frame 1, allowing for adjustment as needed.
[0062] The advantage lies in the appropriate angle and design of the loading frame 13 and transition plate 14, which allow agricultural products to smoothly enter the device from the picking point for processing. As the device moves to different locations, the coordination of these components ensures that agricultural products can always smoothly enter the screening device 10 from the loading device 9, regardless of changes in terrain or location. For example, in a mountainous orchard, even if the ground has a certain slope, the device can adjust its position and the angle of the transition plate 14 to ensure normal transportation and screening of agricultural products.
[0063] Furthermore, it also includes a flattening brush 15, which is arranged on the feeding device 9 and located in front of the cleaning device 11, and first contacts with the agricultural products.
[0064] In this embodiment, the leveling brush 15 is composed of soft nylon bristles of moderate length, effectively leveling the produce without damaging it. The bristles are secured to a brush holder via a slot, which is mounted on the feeding device 9 via an adjustable bracket, allowing the height of the bristles to be adjusted according to the thickness and size of the produce.
[0065] The advantage is that the leveling brush 15 also plays a vital role during the movement of the device, ensuring that the produce is evenly distributed during the loading process, regardless of the device's operating position or angle. Especially in different picking environments, where the placement of produce may be uneven, the leveling brush 15 can automatically adjust to ensure more uniform cleaning and subsequent processing, improving the processing quality of the entire device. For example, in areas where a large amount of produce is piled up, the leveling brush 15 can flatten the produce, ensuring that every piece of produce is fully cleaned and processed.
[0066] Furthermore, the screening device 10 includes a first mounting frame 1001, which is arranged on the frame 1 and located at the rear end of the feeding device 9; there are a number of rollers 1002, and the rollers 1002 are arranged on the first mounting frame 1001 for relative rotation and relative sliding, and the spacing between adjacent rollers 1002 gradually increases from one end of the first mounting frame 1001 close to the feeding device 9 to the other end.
[0067] In this embodiment, the first mounting frame 1001 is welded from high-strength aluminum alloy profiles, offering excellent stability and corrosion resistance. The roller 1002 is a specially surface-treated steel cylinder, mounted on the first mounting frame 1001 via a precision slideway and gear mechanism for relative rotation and sliding. The slideway and gears are lubricated to ensure smooth rotation and sliding. The spacing between adjacent rollers 1002 can be adjusted to accommodate the screening needs of agricultural products of varying sizes.
[0068] The advantage is that this movable and adjustable screening device 10 can be flexibly adjusted to the size of the actual produce at different picking sites. For example, in different orchards or farmlands, faced with different varieties and sizes of produce, the spacing between rollers 1002 can be adjusted with simple operations without having to replace the equipment, thereby improving screening accuracy and efficiency. Furthermore, the structural stability of the device ensures that screening accuracy is not affected during movement, ensuring that each screening achieves the desired effect.
[0069] Furthermore, the drying device 12 includes a second mounting frame 1201, which is arranged on the feeding device 9; there are a number of drying fans 1202, which are evenly arranged on the second mounting frame 1201, located above the feeding device 9, and the wind direction is toward the feeding device 9.
[0070] In this embodiment, the second mounting bracket 1201 is made of sturdy stainless steel and bolted to the loading device 9. It is designed to withstand the vibration and wind generated by the operation of the drying fan 1202. The drying fan 1202 is a small fan with multiple adjustable power levels. The fan blades are optimized to produce uniform hot air. The fan is connected to a controller via electrical wiring, and the air speed and temperature can be adjusted according to the moisture content of the produce and the drying requirements.
[0071] The drying device 12's portability and adjustability allow it to achieve optimal drying results in a variety of environments. At the harvest site, the humidity of produce can vary due to weather and environmental fluctuations. Adjusting the parameters of the drying fan 1202 can meet the drying requirements in various situations. Furthermore, when the device is moved to a different location, it can quickly adapt to the new environment, providing stable drying service for produce and ensuring that the produce does not deteriorate due to excess moisture during storage and transportation.
