Description

Technical Field

[0001] This utility model relates to the field of agricultural technology and is a fruit and vine separation device for processing tomato harvesters. Background Technology

[0002] Currently, the separating roller devices in tomato harvesters all use finger-shaped teeth. When the separating roller device vibrates, the finger-shaped teeth do not have very good wrapping properties, so some vines fall off along with the fruit. Furthermore, because the finger-shaped teeth are relatively hard, they can damage the fruit. In addition, most processing tomato cultivation in China uses a plastic film mulch and drip irrigation system. When the vines fall into the field, the plastic film and drip irrigation tape enter the field along with the vines, causing varying degrees of environmental pollution. Summary of the Invention

[0003] This utility model provides a fruit vine separation device for a tomato harvester, which overcomes the shortcomings of the prior art. It can effectively solve the problem that fruit vines fall with the fruit during the operation of the existing separation roller device, resulting in a large amount of impurities in the processed tomatoes during the harvesting process.

[0004] The technical solution of this utility model is implemented as follows: a fruit and vine separation device for a tomato harvester mainly includes harvesting teeth, a harvesting platform, a fruit and vine conveying chain, a frame, a separation roller device, a fruit and vine conveying device, a fruit sieve, a fruit conveying device, a fan, a fruit lifting conveying device, and a mulch film roller. The harvesting platform includes a power output device, a drive shaft, a driven shaft, and a fruit and vine conveying chain, with harvesting teeth installed at the front of the harvesting platform. The fruit and vine conveying chain moves through the drive shaft and the driven shaft, and a vibrator is installed inside the shaft. A separation roller device is located between the fruit and vine conveying chain and the fruit and vine conveying device. Below the separation roller device is the fruit conveying device, which has a three-stage conveyor chain, with a fan installed in the first stage of the conveyor chain. The fruit and vine conveying device is located behind the separation roller device.

[0005] As a further improvement to this invention, to reduce the impurity rate during seedling separation, the separating roller device has hook-shaped teeth and finger-shaped teeth on its surface, with silicone soft sleeves at the front ends of the finger-shaped teeth and hook-shaped teeth. The hook-shaped teeth and finger-shaped teeth are alternately and staggeredly distributed on a power shaft with an eccentric vibrating block. A spring is installed above and below the driven shaft, and these two springs are placed inside the frame. When the finger-shaped teeth and hook-shaped teeth move to be parallel to the end of the seedling conveyor chain, the distance between them and the seedling conveyor chain is 20mm. The two ends of the separating roller device are placed on the frame, and the separating roller device is connected to the frame by springs.

[0006] As a further improvement to this invention, to reduce the impurity rate in the fruit conveying device, a fruit strainer is distributed below the fruit vine conveyor chain and the separating roller device. The strainer holes are designed to be circular, taking advantage of the shape of the tomatoes being processed and their good flexibility. The size of the strainer holes is determined to be 100mm based on its longitudinal dimension. This distribution and shape minimize the impurity rate and damage rate of the fruit.

[0007] As a further improvement to this invention, to reduce the impurity rate in the fruit conveying device and achieve high efficiency and energy saving, an axial flow fan is installed in the first section of the fruit conveyor chain. This fan is fixed above the frame of the first section of the fruit conveyor chain via a connecting frame. The axial flow fan has low noise and small size, but a large working area. This fan can effectively blow away debris, leaves, and some of the film during the process.

[0008] As a further improvement to this utility model, to reduce the impact of plastic film on tomato harvesters and the environment, a plastic film roller is installed at the tail of the fruit vine conveying device frame. This roller is fixed on the connecting frame at the tail of the frame, located diagonally below the connecting shaft of the fruit vine conveying device, and anti-detachment structures are evenly distributed on the roller.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] like Figures 2-9 As shown, this utility model discloses a fruit and vine separation device for a tomato harvester, mainly comprising harvesting teeth 10, a harvesting platform 8, a fruit and vine conveying chain 9, a frame 3, a separation roller device 1, a fruit and vine conveying device 4, a fruit sieve 14, a fruit conveying device 7, a fan 12, a fruit lifting conveying device 2, and a mulch film roller 5. The harvesting platform 8 includes a power output device, a drive shaft, a driven shaft, and the fruit and vine conveying chain 9. Harvesting teeth 10 are installed in front of the harvesting platform 8, through which tomato vines are harvested. The harvested vines then enter the fruit and vine conveying chain 9 via the harvesting platform 8. The fruit and vine conveying chain 9 moves via the drive shaft and the driven shaft, causing some vibration and separating a small amount of fruit from the vines. Below the separation roller device 1 is the fruit conveying device 7, which has a three-stage conveying chain. The fan 12 is installed in the first stage of the fruit conveying chain 701. The fruit and vine conveying device 4 is located behind the separation roller device 1.

[0023] like Figures 4-6As shown, the surface of the separating roller device 1 is equipped with hook-shaped teeth 106 and finger-shaped teeth 104. The front ends of the finger-shaped teeth 104 and hook-shaped teeth 106 are fitted with silicone soft sleeves 105, and the drive shaft 101 contains an eccentric vibrating block 108. The hook-shaped teeth 106 and finger-shaped teeth 104 are alternately and staggeredly distributed on the drive shaft 101 with the eccentric vibrating block 108. A spring 109 is installed above and below the drive shaft 101, and these two springs 109 are placed inside the frame 3. When the finger-shaped teeth 104 and hook-shaped teeth 106 move to be parallel to the end of the fruit seedling conveyor chain 9, their distance from the fruit seedling conveyor chain 9 is 20mm. The two ends of the separating roller device 1 are placed on the frame 3, and the separating roller device 1 is connected to the frame 3 by the springs 109. When the fruit and vine mixture enters between the hook-shaped teeth 106 and the finger-shaped teeth 104, the power shaft 101 will generate centrifugal force due to the eccentric vibrating block 108, and then vibrate under the action of the spring 109 to separate the fruit and vine, thereby reducing the impurity rate during the separation of the fruit and vine.

[0024] like Figure 7 As shown, the fruit sieve 14 is distributed below the fruit vine conveyor chain 9 and the separating roller device 1. The shape of the sieve holes 141 is designed to be circular, which is more suitable for processing tomatoes and has better flexibility. The size of the sieve holes 141 is determined to be 100mm based on its longitudinal dimension. This distribution and shape minimize the impurity rate and damage rate of the fruit.

[0025] like Figure 8 As shown, an axial flow fan 12 is installed in the first fruit conveyor chain 701. The fan 12 is fixed above the frame of the first fruit conveyor chain 701 via a connecting frame. The fan 12 can effectively blow away debris, leaves, and some film during the process, thereby reducing the impurity content in the fruit conveying device and achieving high efficiency and energy saving.

[0026] like Figure 9 As shown, a plastic film roller 5 is installed at the tail of the machine frame 303. The plastic film roller 5 is fixed on the connecting frame of the tail of the machine frame 303 and is located diagonally below the connecting shaft of the fruit seedling conveying device 4. Anti-detachment structures 501 are evenly distributed on the plastic film roller 5 to reduce the impact of the plastic film on the tomato harvester and the environment.
