[0030] These terms are mainly used to better describe the present application and its embodiments, and are not used to limit that the indicated device, element or component must have a specific orientation, or be constructed and operated in a specific orientation. And, in addition to being able to be used to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present application can be understood according to the specific situation.

[0031] A fruit and vegetable weighing, grading and feeding machine provided by the present invention is located between the loading machine and the weighing and packaging machine in the packaging and conveying line of fruit and vegetable materials. Usually, the feeding machine is arranged below the outlet of the loading machine. The fruit and vegetable materials on the loading machine are conveyed to the feeding machine and then fed to the weighing machine through the fine feeding belt 7 or the coarse feeding belt 8. To further understand the solution of the present invention, specific embodiments will be described.

[0032] Embodiment 1

[0033] Combined withFigures 1-4 As shown in the figure, a fruit and vegetable weighing and grading feeder provided in this embodiment includes a fine feeding belt 7 and a thick feeding belt 8 adjacent to it. The feeding and conveying directions of the fine feeding belt 7 and the thick feeding belt 8 are the same, and the fine feeding belt 7 and the thick feeding belt 8 are driven by different driving components, and fruit and vegetable materials 9 can be conveyed respectively thereon, and all convey the materials 9 into the weighing hopper of the weighing machine. The difference is that, in comparison, the conveyor belt of the thick feeding belt 8 is wider and can convey more fruit and vegetable materials for rough feeding; while the conveyor belt of the fine feeding belt 7 is narrower and usually conveys only one fruit and vegetable material each time for fine feeding.

[0034] Generally, when the weight of the material 9 in the weighing hopper of the weighing machine is far from meeting the weighing requirement, the thick feeding belt 8 runs, and more materials 9 are conveyed to the weighing hopper through the thick feeding belt 8, so that the fruits and vegetables in the weighing hopper quickly approach the weighing requirement. When the fruits and vegetables in the weighing hopper are close to but do not meet the weighing requirement, the thick feeding belt 8 stops feeding, and the fine feeding belt 7 starts feeding. The fruits and vegetables fall into the weighing hopper one by one through the fine feeding belt 7 until the fruits and vegetables in the weighing hopper meet the weighing requirement, and the fine feeding belt 7 stops feeding. Subsequently, the weighing hopper opens to let the fruits and vegetables fall into the packaging box, and the weighing hopper closes again to enter the next feeding.

[0035] The fruit and vegetable weighing and grading feeder in this embodiment further includes a paddle assembly. The paddle assembly includes a paddle 5 and a driving member 1. The paddle 5 is arranged at the material outlet of the thick feeding belt 8, and the paddle 5 is connected to the driving output end of the driving member 1. The driving member 1 is used to drive the paddle 5 to move to correspondingly open or close the material outlet of the thick feeding belt 8.

[0036] When the weight of the material 9 in the weighing hopper is far from meeting the weighing requirement and the thick feeding belt 8 runs for rough feeding, the driving member 1 controls the paddle 5 not to block the material outlet of the thick feeding belt 8, so that the material outlet of the thick feeding belt 8 is opened, and thus rough feeding is carried out. When the fruits and vegetables in the weighing hopper are close to but do not meet the weighing requirement, the driving member 1 controls the paddle 5 to block the material outlet of the thick feeding belt 8, so that the material outlet of the thick feeding belt 8 is closed, the thick feeding belt 8 stops running, and the fine feeding belt 7 starts running for feeding.

[0037] If the paddle 5 is not arranged at the material outlet of the thick feeding belt 8, when the feeding of the thick feeding belt 8 ends, although the fruits and vegetables in the weighing hopper are close to but have not yet met the weighing requirement at this time, the feeding needs to be controlled by the fine feeding belt 7 to weigh accurately. However, in many cases, although the feeding of the thick feeding belt 8 ends and the conveyor belt of the thick feeding belt 8 stops running, some fruits and vegetables located at the material outlet of the thick feeding belt 8 will still fall into the weighing hopper under the influence of inertia or other external factors, affecting the weighing accuracy and easily resulting in an overweight situation.

[0038] In this embodiment, a deflector 5 is provided at the material outlet of the rough feeding belt 8. When the rough feeding of the rough feeding belt 8 ends and the fine feeding belt 7 is required to control the weighing accuracy during feeding, the driving member 1 controls the deflector 5 to block the material outlet of the rough feeding belt 8, closing the material outlet of the rough feeding belt 8, and timely blocking the fruit and vegetable materials at the material outlet of the rough feeding belt 8 to prevent them from falling into the weighing hopper. The weighing accuracy is controlled by fine feeding through the fine feeding belt 7, making the weighing more accurate and avoiding overweighing.

[0039] As a preferred embodiment, the deflector 5 is an elastic deflector. When the deflector 5 blocks the fruit and vegetable materials, using an elastic deflector provides buffering for the fruits and vegetables, avoiding collisions between the deflector 5 and the fruits and vegetables and damaging the fruits. More specifically, the elastic deflector is made of silica gel material, and the lower end of the elastic deflector is divided into several comb teeth, making the buffering performance of the deflector 5 better, and having better protection for medium and small fruits.

[0040] Specifically, the deflector 5 is connected to the support rod 4, and one end of the support rod 4 is connected to the driving output end of the driving member 1. The driving member 1 drives the deflector 5 to rotate reciprocally around the support rod 4. As a further improvement, the driving member 1 is a cylinder, the driving output end of the cylinder is a push rod 2, one end of the push rod 2 is movably connected to one end of the rotating rod 3, and the other end of the rotating rod 3 is fixedly connected to the support rod 4. The driving member 1 is arranged on the mounting side plate 6, and the mounting side plate 6 is located on the frame of the feeder. The frame is a bracket for fixedly installing the feeder. The rotating rod 3 is also movably connected to the mounting side plate 6. For the convenience of description, the movable connection point between the push rod 2 and the rotating rod 3 is the movable connection point A, and the movable connection point between the rotating rod 3 and the mounting side plate 6 is the movable connection point B.

[0041] When weighing starts, the rough feeding belt 8 runs for rough feeding. The cylinder controls the push rod 2 to retract, and the rotating rod 3 rotates simultaneously at the movable connection point A and the movable connection point B. The rotating rod 3 drives the deflector 5 to rotate through the support rod 4, making the lower end of the deflector 5 (illustrated in the middle view direction) move away from the material outlet of the rough feeding belt 8, opening the material outlet of the rough feeding belt 8, and thus performing rough feeding. When the fruits and vegetables in the weighing hopper are close to but do not reach the weighing requirement, the cylinder controls the push rod 2 to push out. The rotating rod 3 drives the deflector 5 to rotate back through the support rod 4, making the lower end of the deflector 5 close to the material outlet of the rough feeding belt 8, closing the material outlet of the rough feeding belt 8, stopping the operation of the rough feeding belt 8, and starting the operation of the fine feeding belt 7 for feeding until the weighing requirement is met. Figure 1 When the fruits and vegetables in the weighing hopper are close to but do not reach the weighing requirement, the cylinder controls the push rod 2 to push out. The rotating rod 3 drives the deflector 5 to rotate back through the support rod 4, making the lower end of the deflector 5 close to the material outlet of the rough feeding belt 8, closing the material outlet of the rough feeding belt 8, stopping the operation of the rough feeding belt 8, and starting the operation of the fine feeding belt 7 for feeding until the weighing requirement is met.

[0042] Preferably, the mounting side plate 6 is arranged between the thin feeding belt 7 and the thick feeding belt 8. The mounting side plate 6 is used to support components such as the driving member 1 on the one hand, and is also used to separate the thin feeding belt 7 and the thick feeding belt 8 to prevent interference of the fruit and vegetable materials conveyed on the thin feeding belt 7 and the thick feeding belt 8. Of course, in other embodiments, the mounting side plate 6 can also be arranged at other positions, and a side plate can be additionally arranged between the thin feeding belt 7 and the thick feeding belt 8.

[0043] Combined with Figure 4 As shown, the material conveying surface of the thin feeding belt 7 is higher than that of the thick feeding belt 8, which can effectively prevent the fruit and vegetable materials on the thick feeding belt 8 from falling onto the thin feeding belt 7 and affecting the thin feeding.

[0044] In this embodiment, a flap assembly is provided. The flap 5 in the flap assembly is arranged at the material outlet of the thick feeding belt 8. After the thick feeding is completed and during the thin feeding process, the flap 5 closes the material outlet of the thick feeding belt 8 to prevent the fruit and vegetable materials at the material outlet of the thick feeding belt 8 from falling into the weighing hopper and affecting the weighing accuracy.

[0045] Embodiment 2

[0046] In the fruit and vegetable weighing and grading feeder provided in this embodiment, the driving member 1 is a motor, and the motor is connected to one end of the support rod 4. The motor is fixedly installed on the frame of the feeder, and the motor drives the support rod 4 to rotate reciprocally.

[0047] Specifically, during thick feeding, the motor drives the support rod 4 to rotate, and the support rod 4 drives the flap 5 to rotate, so that the lower end of the flap 5 moves away from the material outlet of the thick feeding belt 8, and the material outlet of the thick feeding belt 8 is opened. When the thick feeding is completed and the thin feeding starts, the motor drives the flap 5 to rotate back through the support rod 4, so that the lower end of the flap 5 approaches the material outlet of the thick feeding belt 8, and the material outlet of the thick feeding belt 8 is closed.

[0048] The other structures of the fruit and vegetable weighing and grading feeder in this embodiment are the same as those in Embodiment 1.

[0051] To Figure 1It will be described that in this embodiment, the cylinder is arranged in the up and down direction and is disposed above the support rod 4. A bracket can be installed on the frame of the feeder to fix the cylinder. Guide holes in the up and down direction are provided at the connections of the two ends of the support rod 4 with the side plates. The driving output end of the cylinder is connected to the middle position of the support rod 4. When the cylinder drives the support rod 4 to move upward, the paddle 5 leaves the material outlet of the rough feeding belt 8, opening the material outlet of the rough feeding belt 8; when the cylinder drives the support rod 4 to move downward, the paddle 5 approaches the material outlet of the rough feeding belt 8, closing the material outlet of the rough feeding belt 8.
