Description

Technical Field

[0001] The invention relates to the technical field of tomato harvesting, and in particular to a tomato harvesting fruit vine vibration separation system and a tomato harvester. Background Art

[0002] In 2023, the global industrial tomato area will be 4.5 million mu, of which China will account for about 1.2 million mu, accounting for 27%. The planting area has been growing steadily year by year, and the demand for harvesting machinery has been increasing year by year. At present, the main technical difficulties of commercial tomato harvesters are concentrated on the vibration separation of fruit vines. The performance of the fruit vine vibration separation mechanism is the direct cause of the whole machine's harvest impurity rate, loss rate, and breakage rate. The following are common vibration separation structures of traditional machines:

[0003] (1) Driven comb-tooth separation mechanism:

[0004] This is a forced separation mechanism. When the machine moves along the ridge, the comb teeth are inserted into the tomato vines, forcibly pulling the fruits off the branches, and separating the fruits from the stems. The separation process of this model causes great damage to the tomato fruits, and it only separates the fruits, while the stems are still growing in the ground. Removing them requires other follow-up work.

[0005] (2) Drum type separation mechanism:

[0006] The fruit vines are sent to the inclined drum separation device. The drum rotates and lifts and drops the tomato vines several times, so that the fruits fall off and the fruits are separated. This separation mechanism cannot guarantee the separation effect during the separation of fruit vines. When the drum rotates too fast or too slow, the separation effect is not ideal. If the speed is too slow, the separation is incomplete; if the speed is too fast, the separated fruits will not have time to fall and will be thrown into the field together with the tomato vines, resulting in harvest losses.

[0007] (3) Vibration separation mechanism:

[0008] Most vibration separation mechanisms are rotating mechanisms, which ensure unidirectional rotation while achieving periodic changes in speed. The inertial force generated by the change in speed causes the tomato fruits to fall off. Therefore, different separation effects can be achieved by changing the speed of the rotation, and continuous operation can be easily achieved. This type of machine is most widely used in the field of tomato combine harvesters. Summary of the invention

[0009] The invention provides a tomato harvesting fruit vine vibration separation system and a tomato harvester, aiming to solve the problems in the prior art.

[0010] The technical solution of the present invention to solve the above technical problems is as follows:

The tomato plants (with tomatoes) and the mixture of ground film / drip irrigation tape are continuously transported backwards via the secondary conveyor belt 2, wherein the ground film / drip irrigation tape is wound around the anti-winding roller 4 under the action of the teeth on the secondary conveyor belt 2 and the rotation of the anti-winding roller 4.

[0106] 3. The tomato plants (with tomatoes) are transported backward along the channel between the upper grille 5 and the lower stripping fingers 6. During the process, they are vibrated and beaten by the vibrating rods on the vibrating rollers 8 to separate the tomatoes from the tomato vines. The tomatoes fall from the gaps between the lower stripping fingers 6 to the fruit belt 9 and continue to be transported backward. The tomato vines slide along the lower stripping fingers 6 to the vine belt 10 and continue to be transported backward.

[0107] The separation system provided by the present invention has the following advantages:

[0108] 1. The conveyor belt is divided into a primary conveyor belt 1 and a secondary conveyor belt 2, with a gap reserved in the middle. Tomatoes that are more mature and have been separated from the tomato vines do not need to pass through the vibration roller and fall directly from here to the fruit belt 9. This can be diverted in advance, reduce the vibration separation pressure, reduce the risk of blockage, and improve the separation efficiency. At the same time, this part of the tomatoes can avoid being beaten by the vibration rod, reducing the breakage rate.

[0109] 2. Multiple rows of barbed teeth 2-1 are added to the secondary conveyor belt 2 to play a guiding role, thereby improving the conveying efficiency of tomato plants. At the same time, impurities such as mulch film / drip irrigation tape are guided to the anti-entanglement roller 4. The anti-entanglement roller 4 rotates to wrap the mulch film / drip irrigation tape around the anti-entanglement roller groove 4-1, which is convenient for regular cleaning. The unique barbed teeth can ensure that impurities such as mulch film / drip irrigation tape are brought to the anti-entanglement roller 4 and not taken away.

[0110] 3. The upper grid 5 is arranged in an array, which is the upper boundary of the tomato plant movement, preventing the tomato vine from being entangled on the vibrating roller 8. The lower fingers 6 are staggered and stepped by long fingers 6-1 and short fingers 6-2. The front fingers are densely arranged to prevent the tomato plant from sagging from the gaps between the fingers, which causes the vibrating rod 8-1 to not work effectively and cause incomplete tomato separation. The rear fingers are sparsely arranged to promote the rapid drop of the separated tomatoes. This effectively solves the problem of incomplete separation of tomatoes and tomato vines and low separation efficiency.

[0111] 4. The vibrator 7 is mainly composed of three pendulums 7-2 with exactly the same shape and mass. The relative angle of the pendulum 7-2 is kept unchanged by the synchronous belt 7-3 and the synchronous pulley 7-4. The hydraulic motor drives the driving wheel 7-5 to rotate during operation. The pendulum 7-2 is driven by the synchronous belt 7-3 to rotate at high speed to generate a periodically changing force, which provides a periodically changing acceleration to the vibrator 7, which is transmitted to the vibration roller 8 through the bracket 7-1, and finally manifested as the rotation and vibration of the vibration roller 8. During the vibration process, the vibration rod 8-1 knocks the tomato vines in the channel to make the tomatoes fall off. The tomatoes fall into the fruit belt through the gap of the lower finger 6, and the tomato vines slide along the lower finger 6 and fall into the vine belt to achieve fruit vine separation.

[0112] The double pendulum vibrator is upgraded to a three-pendulum structure, which reduces the mass of a single pendulum while increasing stability. The original gear drive of the pendulum is upgraded to a synchronous belt drive, which reduces costs and can absolutely guarantee the relative angle of the pendulum, ensuring the balance performance of the system. At the same time, it has a certain overload protection function to prevent damage to the mechanical structure.

[0113] 5. The vibration roller 8 is mainly composed of vibration rods 8-1. The number of vibration rods is increased on the basis of the transmission structure. The original vertical structure is adjusted to a 15-degree structure. The two adjacent rows are staggered and stepped to effectively reduce the vibration rod knocking angle and reduce tomato damage. At the same time, the vibration rod material is upgraded to glass fiber + high-pressure resin, which has a certain elasticity to reduce tomato damage. The anti-entanglement belt 8-2 prevents the impurities such as drip irrigation tape / ground film left behind from being entangled in the gap between adjacent vibration rods. The synchronous rubber disc 8-3 fixed structure improves the convenience of maintenance and replacement.

[0114] The present invention solves the problem of high tomato breakage rate and reduces the loss rate; at the same time, the present invention also solves the problem of incomplete separation of tomatoes and tomato vines and low separation efficiency in the existing mechanism, reduces the loss rate and improves the harvesting efficiency; in addition, the present invention also solves the problem that the separation mechanism is easily damaged by grass and is difficult to repair and replace.
