[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides an adjustable feeder for a fruit and vegetable sorting machine, including a frame 1 with four crossbeams 1a on the frame 1; Conveying mechanism 2 is mounted on four crossbeams 1a; The power mechanism 3 is mounted on the two lower crossbeams 1a and connected to the conveying mechanism 2; The feeding assembly 4 and the material distribution assembly 5 are respectively installed on the two upper crossbeams 1a, with the material distribution assembly 5 located below the feeding assembly 4; The unloading rack 6 is located at the top of the frame 1; Mounting plate 7 is set inside frame 1 and below material distribution component 5. Several material distribution racks 8 are set on mounting plate 7. Both the unloading rack 6 and the mounting plate 7 are inclined. The feeding rack 6 is used to spread the fruits and vegetables flat and guide them to be conveyed to the bottom of the conveying mechanism 2; the conveying mechanism 2 is used to convey the fruits and vegetables to one side; the feeding component 4 can support the bottom of the fruits and vegetables and divide them according to their particle size during the conveying process; the dividing component 5 can guide the divided fruits and vegetables to the corresponding dividing rack 8 to complete the feeding.

[0017] Specifically, refer to Figure 2 The conveying mechanism 2 includes a bearing 21, a rotating rod 22, a transmission wheel 23, and a conveyor belt 24. There are eight shaft seats 21 in total, which are installed on the four crossbeams 1a respectively. The installation is secured by bolts and other means. The shaft seats 21 provide rotation support points for the rotating rod 22. The rotating parts such as bearings are installed inside, which can effectively reduce the friction when the rotating rod 22 rotates, ensure the smooth rotation of the rotating rod 22, and thus ensure the stable operation of the conveying mechanism 2. The rotating rod 22 is inserted into the front and rear bearings 21 at its front and rear ends respectively, and is adapted to the rotating parts inside the bearings 21 to achieve stable rotation; a number of transmission wheels 23 are sleeved on the outer wall of the rotating rod 22 at a certain interval, and the transmission wheels 23 are fixed to the rotating rod 22 by means of key connection or other means to ensure that the power can be efficiently transmitted to the transmission wheels 23. The drive wheel 23 is sleeved on the outer wall of the rotating rod 22 and rotates together with the rotating rod 22. Its function is to drive the conveyor belt 24 to move. The size and spacing of the drive wheel 23 are designed according to the specifications of the conveyor belt 24 and the conveying requirements to ensure a tight fit with the conveyor belt 24 and avoid slippage. The conveyor belt 24, fitted onto four opposing drive wheels 23, is made of wear-resistant, non-slip rubber or polyurethane material. This material not only adapts to the environment of fruit and vegetable transportation, reducing damage to the fruits and vegetables, but also has a long service life. The conveyor belt 24 achieves a cyclical conveying action through the rotation of the drive wheels 23. The fruits and vegetables fall into the gap between the two conveyor belts 24 and are conveyed to one side by the friction between them and the conveyor belts 24. This structure cleverly utilizes the gap to achieve the initial bearing and guiding of the fruits and vegetables.

[0018] Specifically, refer to Figure 2 The power mechanism 3 includes a support plate 31, a DC controller 32, a DC motor 33, a sprocket 34, and a chain 35; There are two support plates 31, which are fixed to the top of the two lower crossbeams 1a respectively. They are installed by welding or bolting to provide a stable mounting carrier for the DC controller 32 and the DC motor 33. The support plates 31 have sufficient strength to withstand the weight of the motor and other components and the vibration generated during the operation of the equipment, so as to ensure the stable operation of the power mechanism 3. The DC controller 32 is installed on the top of one of the support plates 31 and is electrically connected to the DC motor 33. Its core function is to precisely control the speed of the DC motor 33. By adjusting the motor speed, it can flexibly adapt to the conveying needs of different fruits and vegetables. For example, for easily damaged soft fruits and vegetables such as strawberries, the conveying speed can be reduced to reduce damage; for hard fruits and vegetables such as apples, the speed can be appropriately increased to improve the screening efficiency. A DC motor 33 is mounted on top of another support plate 31 and works in conjunction with a DC controller 32. Its output end is connected to a sprocket 34 to provide power to the conveying mechanism 2. The motor is selected to have good speed regulation performance and stable torque to ensure that the conveying mechanism 2 can operate stably and continuously. Two sprockets 34 are respectively installed at the output end of the DC motor 33 and on the outer wall of one of the rotating rods 22, and are connected by a chain 35 for transmission. The tooth shape and size of the sprockets 34 are precisely designed to ensure good meshing with the chain 35 and efficient power transmission. Chain 35 connects two sprockets 34, transmitting the power of DC motor 33 to rotating rod 22, thereby driving the conveying mechanism 2 to run; the transmission method of sprockets 34 and chain 35 has advantages such as accurate transmission ratio, high efficiency, and adaptability to harsh environments. Fruit and vegetable processing environments contain certain moisture and impurities, and the transmission is less affected by them.

[0019] Specifically, refer to Figure 3 The feeding assembly 4 includes a support base 41, an insert rod 43, and a material distribution bar 44. The outer wall of the support base 41 is provided with a support hole 42, and the support hole 42 extends downward to form a number of accommodating cavities. There are six support bases 41, which are respectively installed on the two upper crossbeams 1a and fixed by bolts and other means, providing a support base for the insertion rod 43 and the material distribution bar 44. The support base 41 has support holes 42 on its outer wall and several accommodating cavities extending downward. The number and spacing of the accommodating cavities are designed according to the common fruit and vegetable screening particle size requirements, providing multiple positions for adjusting the position of the material distribution bar 44. The insert rod 43 is inserted into the support holes 42 on the front and rear support seats 41 respectively. It is made of high-strength metal rod to ensure that it has sufficient strength to support the material distribution strip 44 and withstand the force generated when the fruit and vegetable are distributed. By inserting the insert rod 43 into different accommodating cavities, the position of the material distribution strip 44 can be changed, thereby adjusting the size of the fruit and vegetable sieve. The material separating bars 44 are arranged on three insert rods 43, and their number is equal to that of the conveyor belt 24. The spacing between two adjacent material separating bars 44 gradually increases along the conveying direction. When fruits and vegetables are conveyed by the conveying mechanism 2, when they reach the position of the material separating bar 44 corresponding to their particle size, they will pass through the gap between the two relative material separating bars 44 under the action of gravity, thus achieving preliminary screening according to particle size. This design with gradually changing spacing can adapt to the sequential screening of fruits and vegetables of different particle sizes. Small-sized fruits and vegetables are screened first, and large-sized fruits and vegetables are screened later, which can effectively avoid the occurrence of blockage.

[0020] Specifically, refer to Figure 4 The material distribution component 5 includes a support frame 51, a support rod 53, and a guide plate 54; The support frame 51 is installed on the two upper crossbeams 1a respectively. It adopts a J-shaped plate structure and has good structural strength and load-bearing capacity. Several load-bearing holes 52 are opened on its outer wall. The distribution spacing of the load-bearing holes 52 is adapted to the material distribution requirements, which provides conditions for the position adjustment of the support rod 53. The support rod 53, several of which are slidably inserted into the front and rear support holes 52, are made of metal rods or high-strength plastic rods to ensure that they have sufficient strength to support the guide plate 54; by changing the position of the support rod 53 inserted into different support holes 52, the guiding range formed by two adjacent guide plates 54 can be adjusted, thereby adapting to the precise falling of fruits and vegetables of different particle sizes into the corresponding material distribution rack 8 after screening. The guide plate 54 is set on the outer wall of the support rod 53. It adopts a wing-shaped structure on both sides to guide the fruits and vegetables. When the fruits and vegetables pass through two adjacent dividing strips 44, they will fall on the guide plate 54 and fall into the corresponding dividing rack 8 under the guidance of the guide plate 54 to complete the feeding, ensuring the accuracy of the feeding.

[0021] Specifically, refer to Figure 4 The bearing rod 53 is provided with limiting seats 9 at both ends, which are in contact with the bottom wall of the inner cavity of the bearing frame 51. Their function is to prevent the bearing rod 53 from rotating in the bearing hole 52, keep the guide plate 54 in a horizontal state, ensure that the guide plate 54 guides the fruits and vegetables in a stable and accurate direction, and avoid the guide plate 54 from tilting due to the rotation of the bearing rod 53, which would affect the accuracy of the fruits and vegetables falling into the sorting rack 8.

[0022] Specifically, refer to Figure 1 The frame 1 is equipped with a fixed frame 10 located above the conveyor mechanism 2; two threaded rods 11 are respectively threaded to the top of the fixed frame 10; and guide frames 12 are rotatably sleeved on the outer walls of the two threaded rods 11 at both ends. The guide frames 12 have toothed structures and the number of toothed structures is equal to that of the conveyor belts 24. The toothed structures can guide the fruits and vegetables falling on the conveyor belts 24 to the two opposite conveyor belts 24 to prevent the fruits and vegetables from stacking. The height and angle of the guide frames 12 can be adjusted by rotating the threaded rods 11 to adapt to the guidance needs of different fruits and vegetables.

[0023] Working principle During the fruit and vegetable conveying stage, in the power mechanism 3, the DC controller 32 controls the DC motor 33 to start, and the sprocket 34 at the output end of the motor rotates. This rotation is caused by the chain 35 to drive the sprocket 34 on the rotating rod 22 to rotate, which in turn causes the rotating rod 22 to rotate. The transmission wheel 23 on the rotating rod 22 drives the conveyor belt 24 to circulate. The fruits and vegetables are placed on the unloading rack 6 and, relying on the inclination angle of the unloading rack 6 and their own weight, they are laid flat and slide towards the conveying mechanism 2, falling into the gap between the two conveyor belts 24. Under the action of the friction of the conveyor belts 24, they are conveyed to one side. During the fruit and vegetable screening stage, the feeding component 4 plays a role in the conveying process. As the spacing between adjacent dividing strips 44 gradually increases in the reverse direction of the conveying, the fruits and vegetables are conveyed with the conveyor belt 24. Fruits and vegetables with smaller particle sizes first reach the position of the dividing strip 44 with a spacing that can accommodate their passage. Under the action of gravity, they pass through the gap between two relative dividing strips 44, achieving preliminary screening. Fruits and vegetables with larger particle sizes continue to be conveyed with the conveyor belt 24 until they reach the position of the dividing strip 44 with the corresponding spacing to complete screening. At the same time, the spacing of the dividing strips 44 can be changed by adjusting the position of the insertion rod 43 in the receiving cavity of the support seat 41 to adapt to the screening requirements of different fruit and vegetable particle sizes and flexibly adjust the screening range. During the material collection stage, the fruits and vegetables screened by the feeding component 4 fall onto the guide plate 54 of the feeding component 5. Guided by the guide plate 54, they fall into the corresponding feeding rack 8 to complete the feeding. By adjusting the position of the guide plate (54) left and right (changing the position of the bearing rod 53 in the bearing hole 52 of the bearing rack 51), the guiding range formed by the guide plate 54 can be adjusted so as to adjust the falling position according to the size of the fruit particles, ensuring that fruits and vegetables of different particle sizes fall accurately into the corresponding feeding rack 8. In addition, the guide rack 12 in the frame 1 guides the fruits and vegetables falling on the conveyor belt 24 to the gap of the conveyor belt 24 through the toothed structure to prevent the fruits and vegetables from stacking and ensure smooth conveying and screening process.
