Description

Technical Field

[0001] This invention relates to the field of harvester conveying devices, and more particularly to an agricultural machinery auxiliary delivery device. Background Technology

[0002] Vegetable harvesting and conveying equipment is a type of agricultural machinery specifically designed to improve vegetable harvesting efficiency and reduce manual labor intensity. This equipment typically integrates cutting, collecting, and conveying functions, enabling direct harvesting of vegetables in the field and transporting them to designated containers or vehicles, achieving seamless integration from the field to storage or processing.

[0003] While existing vegetable harvesting devices can effectively improve work efficiency and reduce manual labor intensity during harvesting operations, they still have some shortcomings in practical applications. In particular, when processing root vegetables or vegetables that grow close to the ground, they tend to bring a large amount of soil into the collection box, causing many inconveniences for subsequent processing and cleaning. Summary of the Invention

[0004] The purpose of this invention is to provide an agricultural machinery-assisted delivery device that can clean soil and other impurities from the surface of vegetables during transportation, thereby reducing the impurity content and facilitating subsequent processing.

[0005] To achieve the above objectives, the present invention provides an agricultural machinery auxiliary delivery device, including a base, a mobile track, and a storage component. The mobile track is disposed at the bottom of the base, and the storage component is disposed on the base. The device also includes a harvesting component and a conveying component. The conveying component includes a contact plate, a first rotating belt, multiple support plates, a second rotating belt, an adjuster, and a cleaning brush. The first rotating belt is disposed on one side of the base, and the contact plate is rotatably disposed at the bottom of the first rotating belt for placing vegetables harvested by the harvesting component onto one side of the first rotating belt. The second rotating belt is disposed on one side of the first rotating belt, and the multiple support plates are fixed to the second rotating belt. The rotation of the second rotating belt drives the support plates to push the harvested vegetables along the first rotating belt. The first and second rotating belts rotate at different speeds to rotate the vegetables during movement. The adjuster is slidably disposed above the second rotating belt, and the cleaning brush is connected to the output end of the adjuster.

[0006] The harvesting assembly includes a rotating rod, a cutting blade, a pusher plate, and a rotating motor. The rotating rod is rotatably mounted below the base, the cutting blade is fixed to the rotating rod, the pusher plate is fixed to the rotating rod, and the output end of the rotating motor is connected to the rotating rod.

[0007] The contact plate includes a contact plate body, a pull block, a pull rod, and a pull cylinder. The contact plate body is rotatably disposed on one side of the base, the pull block is slidably disposed on the contact plate body, and the pull rod is rotatably connected to the pull block and connected to the output end of the pull cylinder.

[0008] The contact plate body has multiple drainage holes, which are distributed on the contact plate body.

[0009] The support plate includes a support plate body, a sliding plate, and an elastic element. The sliding plate is slidably disposed within the support plate body, and the elastic element is disposed between the support plate body and the sliding plate.

[0010] The cleaning brush includes a brush body, a second support plate, a second elastic element, and a cleaning motor. The second support plate is slidably disposed on the adjuster, the second elastic element is disposed between the second support plate and the adjuster, the brush body is rotatably disposed on the second support plate, and the output end of the cleaning motor is connected to the brush body.

[0011] The conveying assembly further includes a fan and an air outlet plate. The air outlet plate has multiple air outlet holes and is fixed to one side of the support plate. The fan is connected to the air outlet plate.

[0012] The conveying assembly also includes two side plates, which are disposed on both sides of the first rotating belt to restrict the movement of the vegetables.

[0013] The conveying assembly further includes a collection box, which is located below the first rotating belt and has multiple discharge holes.

[0014] The collection box includes a collection box body, two triangular push plates, a push screw, and a push motor. The two triangular push plates are slidably disposed in the collection box body. The push screw has two opposite threads and is threadedly connected to the two triangular push plates. The output end of the push motor is connected to the push screw.

[0015] This invention discloses an agricultural machinery auxiliary delivery device. The mobile track is located at the bottom of the base, enabling the device to adapt to different farmland terrains and move and operate flexibly. The storage component is located on the base for temporarily storing harvested vegetables or other crops, facilitating subsequent centralized transportation or processing. The harvesting component is responsible for cutting and collecting the crops, neatly feeding them into the conveying component, thereby achieving automated connection from harvesting to conveying and improving overall operational efficiency.

[0016] The first rotating belt is located on one side of the base and serves as the main conveyor, responsible for transferring the harvested vegetables from the harvesting assembly to the subsequent processing area.

[0018] The second rotating belt is positioned on one side of the first rotating belt, and multiple support plates are evenly fixed to the second rotating belt. When the second rotating belt rotates, it drives the support plates to move synchronously, propelling the harvested vegetables forward along the direction of the first rotating belt.

[0019] To improve stability during transport and facilitate the removal of impurities from the vegetable surface, the first and second rotating belts are set to rotate at different speeds. This speed difference design allows the vegetables to rotate during transport.

[0020] The regulator is slidably positioned above the second rotating belt, and its position can be adjusted according to actual operational needs to control the spacing or pressure between the support plates, adapting to crops of different sizes or types. The cleaning brush is connected to the output end of the regulator and can clean dirt and other impurities from the surface of the vegetables during transport, thereby reducing the impurity content and facilitating subsequent processing.

[0029] See also Figures 1-4This invention provides an agricultural machinery auxiliary delivery device, including a base 101, a mobile track 102, and a storage component 103. The mobile track 102 is disposed at the bottom of the base 101, and the storage component 103 is disposed on the base 101. It also includes a harvesting component 104 and a conveying component. The conveying component includes a contact plate 106, a first rotating belt 107, multiple support plates 108, a second rotating belt 109, an adjuster 110, and a cleaning brush 111. The first rotating belt 107 is disposed on one side of the base 101, and the contact plate 106 is rotatably disposed at the bottom of the first rotating belt 107 for conveying the harvesting component 104. The harvested vegetables by the harvesting assembly 104 are placed on one side of the first rotating belt 107, and the second rotating belt 109 is disposed on one side of the first rotating belt 107. A plurality of the support plates 108 are fixed on the second rotating belt 109. The second rotating belt 109 rotates, causing the support plates 108 to push the harvested vegetables along the first rotating belt 107. The rotation speeds of the first rotating belt and the second rotating belt 109 are different to drive the vegetables to rotate during the movement. The regulator 110 is slidably disposed above the second rotating belt 109, and the cleaning brush 111 is connected to the output end of the regulator 110.

[0030] In this embodiment, the mobile track 102 is disposed at the bottom of the base 101, enabling the device to adapt to different farmland terrains and move and operate flexibly. The storage component 103 is disposed on the base 101 for temporarily storing harvested vegetables or other crops, facilitating subsequent centralized transportation or processing. The harvesting component 104 is responsible for cutting and collecting the crops, neatly feeding them into the conveying component, thereby achieving automated connection from harvesting to conveying and improving overall operational efficiency.

[0031] The first rotating belt 107 is located on one side of the base 101 and serves as the main conveying carrier, responsible for transferring the harvested vegetables from the harvesting assembly 104 to the subsequent processing area.

[0032] The contact plate 106 is rotatably mounted at the bottom of the first rotating belt 107, which can maintain a certain degree of contact with the ground during operation, ensuring that the harvested vegetables can be smoothly guided to one side of the first rotating belt 107, and avoiding leakage or jamming.

[0033] The second rotating belt 109 is disposed on one side of the first rotating belt 107, and a plurality of the support plates 108 are evenly fixed on the second rotating belt 109. When the second rotating belt 109 rotates, it drives the support plates 108 to move synchronously, pushing the harvested vegetables forward along the direction of the first rotating belt 107.

[0034] To improve stability during transport and facilitate the removal of impurities from the vegetable surface, the rotational speeds of the first rotating belt 107 and the second rotating belt 109 are set differently. This speed difference design allows the vegetables to rotate during movement.

[0035] The regulator 110 is slidably disposed above the second rotating belt 109, and its position can be adjusted according to actual operational needs to control the spacing or pressure between the support plates 108, adapting to crops of different sizes or types. The cleaning brush 111 is connected to the output end of the regulator 110, and can clean dirt and other impurities from the surface of the vegetables during the conveying process, thereby reducing the impurity content and facilitating subsequent processing.

[0036] The harvesting assembly includes a rotating rod 112, a cutting blade 113, a pusher plate 114, and a rotating motor 115. The rotating rod 112 is rotatably disposed below the base 101, the cutting blade 113 is fixed on the rotating rod 112, the pusher plate 114 is fixed on the rotating rod 112, and the output end of the rotating motor 115 is connected to the rotating rod 112.

[0037] At least one cutting blade 113 is fixedly mounted on the rotating rod 112 along its axial direction. The cutting blade 113 is made of high-strength, wear-resistant material and has a sharp cutting edge, which can efficiently cut crop stems or other plant parts. According to actual operation needs, multiple cutting blades 113 can be arranged on the rotating rod 112 to achieve simultaneous cutting of crops of different heights or densities, thereby improving operation efficiency.

[0038] In addition, at least one push plate 114 is fixedly provided on the rotating rod 112. The push plate 114 has an arc-shaped or inclined structure and is located behind or to the side of the cutting blade 113. When the rotating rod 112 rotates, the push plate 114 rotates synchronously with it and pushes the cut vegetables backward onto the contact plate 106 during the cutting process for further processing.

[0039] The rotary motor 115 serves as the power source for the harvesting assembly. Its output end is fixedly connected to one end of the rotating rod 112 via a coupling or transmission mechanism, driving the rotating rod 112 and its cutting blade 113 and push plate 114 to rotate at high speed. The rotary motor 115 can be selected as either a hydraulic motor or an electric motor according to actual needs, possessing good starting performance and speed regulation functions. This allows operators to adjust the cutting speed according to different crop types and growth stages, improving equipment adaptability and operational efficiency.

[0040] The contact plate 106 includes a contact plate body 116, a pull block 117, a pull rod 118, and a pull cylinder 119. The contact plate body 116 is rotatably disposed on one side of the base 101. The pull block 117 is slidably disposed on the contact plate body 116. The pull rod is rotatably connected to the pull block 117 and connected to the output end of the pull cylinder 119.

[0041] The contact plate body 116 has a plurality of holes 120, which are distributed on the contact plate body 116.

[0042] The contact plate body 116 is rotatably mounted on one side of the base 101 via a rotating shaft structure, allowing it to swing and adjust within a certain angle range. This allows the contact plate body 116 to be rotated after vegetables enter it, placing them onto the support plate 108 of the second rotating belt 109 for further transport. The drain holes 120 screen off dirt, debris, and other impurities adhering to the vegetables, providing initial cleaning.

[0043] The support plate 108 includes a support plate body 121, a sliding plate 122 and an elastic element 123. The sliding plate 122 is slidably disposed within the support plate body 121, and the elastic element 123 is disposed between the support plate body 121 and the sliding plate 122.

[0044] The support plate 108 includes a support plate body 121, a sliding plate 122, and an elastic element 123. The support plate body 121 is fixedly mounted on the second rotating belt 109 and serves as the main structural component for supporting and guiding the movement of crops. Its overall design is strip-shaped or arc-shaped, and it has good mechanical strength and wear resistance, enabling it to withstand the impact and friction generated by materials during continuous conveying.

[0045] A groove or guide cavity is provided inside the support plate body 121, through which the sliding plate 122 can slide along the length or perpendicular direction of the support plate body 121. The outer end face of the sliding plate 122 is used to contact the crops during the conveying process and generate a pushing force on its surface, propelling the vegetables forward along the first rotating belt 107. The design of the sliding plate 122 gives the support plate 108 a certain degree of buffering and adaptability during the pushing process, and can adjust its height or angle according to the size of the crops, avoiding obstruction of equipment operation due to material accumulation or jamming.

[0046] Specifically, when encountering large or stacked vegetables during the conveying process, the sliding plate 122 experiences an upward reaction force under manual operation, overcoming the elastic force of the elastic element (such as a compression spring or rubber pad) and sliding upward along the guide groove inside the support plate body, thereby achieving height adaptive adjustment. When the material volume is small or after passing through, the sliding plate is manually pushed back to its initial position. This structure is equivalent to a mechanical floating pusher, which can provide a buffer stroke (e.g., 5~15mm) in the vertical direction, preventing the rigid pusher from causing overload of the transmission system or damage to the vegetables due to excessive resistance.

[0047] The cleaning brush 111 includes a brush body 124, a second support plate 125, a second elastic element 126, and a cleaning motor 127. The second support plate 125 is slidably disposed on the adjuster 110, and the second elastic element 126 is disposed between the second support plate 125 and the adjuster 110. The brush body 124 is rotatably disposed on the second support plate 125, and the output end of the cleaning motor 127 is connected to the brush body 124.

[0048] The second support plate 125 is slidably mounted along the length of the adjuster 110 via a sliding structure, allowing the cleaning brush 111 to be laterally adjusted according to its actual working position to meet the cleaning needs of different areas. As a key component connecting the brush body 124 and the adjuster 110, the second support plate 125 possesses excellent mechanical strength and wear resistance, and can withstand the friction and vibration impacts generated during continuous operation.

[0049] A second elastic element 126, preferably a compression spring, torsion spring, or hydraulic buffer device, is provided between the second support plate 125 and the adjuster 110. Its function is to provide a certain elastic support force, allowing the brush body 124 to automatically adjust the contact pressure with the surface being cleaned within a certain range. When encountering unevenness or protruding foreign objects, the second elastic element 126 can act as a buffer to prevent damage to the brush body 124 or the conveying components due to overload, while also improving the consistency and stability of the cleaning effect.

[0050] The brush body 124 is rotatably mounted on the second support plate 125 via bearings or a rotating shaft, enabling it to rotate at high speed around its own axis, thereby enhancing cleaning efficiency and effectively removing impurities adhering to vegetables. The cleaning motor 127 serves as the drive source, its output end connected to the brush body 124 via a coupling, gear drive, or belt drive, driving the brush body 124 to operate continuously. The cleaning motor 127 can be a DC motor, AC motor, or hydraulic motor, and has a speed control function to flexibly control the rotation speed of the brush body 124 according to different cleaning intensity requirements.

[0051] The conveying assembly also includes a fan 128 and an air outlet plate 129. The air outlet plate 129 has a plurality of air outlet holes 130. The air outlet plate 129 is fixed to one side of the support plate 108. The fan 128 is connected to the air outlet plate 129.

[0052] The conveying assembly also includes a fan 128 and an air outlet plate 129. The air outlet plate 129 has multiple evenly distributed air outlet holes 130. The air outlet holes 130 can be designed in various forms such as circular, elliptical, or strip-shaped according to actual needs to achieve reasonable airflow distribution. The air outlet plate 129 is fixedly installed on one side of the support plate 108, preferably located near the first rotating belt 107. It has an internal air duct structure connected to the fan 128, so that airflow can be transported from the fan 128 through the air duct to each air outlet hole 130, and finally evenly blown onto the surface of the vegetables during the conveying process. The fan 128, as an airflow power source, is connected to the air outlet plate 129 through an air duct or direct connection, and can generate airflow with a certain pressure to assist in cleaning and stabilize the conveying process. Specifically, as the vegetables are pushed along the first rotating belt 107 by the support plate 108, the fan 128 continuously blows out airflow through the air outlet plate 129, which can blow off the dust, debris and other impurities attached to the surface of the vegetables, thus playing a further cleaning role.

[0053] The conveying assembly also includes two side plates 131, which are disposed on both sides of the first rotating belt 107 to restrict the movement of the vegetables.

[0054] The conveying assembly also includes two side plates 131, symmetrically arranged on both sides of the first rotating belt 107 and extending a certain length along the conveying direction. The side plates 131 are made of lightweight, high-strength materials, such as aluminum alloy or engineering plastics, and have good wear resistance and corrosion resistance. Their main function is to limit the lateral movement of vegetables during conveying, preventing them from falling off the edge of the first rotating belt 107 or deviating from the predetermined path, thereby improving the stability and safety of the conveying process.

[0055] The conveying assembly also includes a collection box, which is located below the first rotating belt, and the first rotating belt has multiple discharge holes.

[0056] The conveying assembly also includes a collection box, which is located below the first rotating belt and is used to receive materials that fall off the conveyor belt, such as impurities, broken leaves, or small particles that fall off the surface of vegetables.

[0057] Multiple discharge holes are provided on the upper surface or edge area of ​​the first rotating belt. These discharge holes are evenly distributed at a certain interval, and their size is designed according to the type of crop being processed and the size of the impurity particles. This ensures that impurities fall smoothly without causing whole vegetables or other crops to pass through the holes and fall in. When the first rotating belt is running, as the vegetables move on its surface, smaller impurities such as soil and debris attached to them will gradually sink due to vibration or airflow and fall into the collection box below through the discharge holes, thus achieving the initial screening and cleaning function of the materials.

[0058] The collection box includes a collection box body 132, two triangular push plates 133, a push screw 134, and a push motor 135. The two triangular push plates 133 are slidably disposed within the collection box body 132. The push screw 134 has two opposite threads and is threadedly connected to the two triangular push plates 133. The output end of the push motor 135 is connected to the push screw 134.

[0059] The collection box body 132 is a container with a closed structure, typically made of metal sheet or high-strength plastic, with internal space used to store impurities or waste falling from the first rotating belt. Its top opening faces the discharge hole area of ​​the first rotating belt to ensure that the material can fall accurately into the box; the bottom is equipped with an openable discharge door or sliding cover for easy periodic cleaning.

[0060] Two triangular push plates 133 are symmetrically slidably disposed on the two side guide rails inside the collection box body 132. Their cross-sections are inverted "V" or triangular structures, and they can move relative to each other in the horizontal direction inside the box. The main function of the triangular push plates 133 is to gather the material falling into the box towards the center and push it towards the discharge port when discharge is required, thereby improving discharge efficiency and preventing material accumulation and blockage.

[0061] The pusher plates are arranged symmetrically. They are positioned on the path of the material after cutting. Although their linear velocity is the same as that of the cutting blade, they do not have sharp edges, have a smooth surface, and have an elastic coating (such as rubber), so they will not damage the cut vegetables during the gentle pushing process. The push screw 134 passes through the middle of the collection box body 132 and has two threads in opposite directions, which respectively engage with the threaded holes on the two triangular push plates 133. When the push screw 134 rotates, because the two threads are in opposite directions, the two triangular push plates 133 will move synchronously inward or outward under the drive of the screw, realizing the pushing or dispersing operation of materials.

[0062] The drive motor 135 is fixedly installed on one side of the collection box body 132, and its output end is connected to one end of the drive screw 134 through a coupling or gear transmission mechanism to drive it to rotate.

[0063] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
