Description

Technical Field

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

[0002] In 2023, the global industrial tomato plantation area reached 4.5 million mu (approximately 1.2 million mu), with China accounting for approximately 27%. This cultivated area has steadily increased year by year, and the demand for harvesting machinery has also increased. Currently, the main technical difficulty in commercial tomato harvesters lies in the vibratory separation of the fruit vines. The performance of the vibratory separation mechanism directly affects the overall harvested trash content, loss rate, and breakage rate. Common types of vibratory separation mechanisms used in conventional harvesters are:

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

[0004] This is a forced separation mechanism. As the machine travels along the rows, the comb teeth penetrate the tomato vines, forcibly pulling the fruit off the branches and separating the fruit from the stems. This separation process causes significant damage to the tomato fruit, and it only separates the fruit, while the stems remain in the field, requiring further work to remove them.

[0005] (2) Drum type separation mechanism:

[0006] The tomato vines are fed into an inclined drum-type separation device. The drum rotates, repeatedly lifting and lowering the vines, causing the fruit to fall off and separate. However, this separation mechanism cannot guarantee effective separation. When the drum rotates too fast or too slow, the separation is unsatisfactory. Too slow results in incomplete separation; too fast results in incomplete separation, and the separated fruit does not have time to fall and is thrown into the field along with the tomato vines, resulting in harvest losses.

[0007] (3) Vibration separation mechanism:

[0008] Vibratory separation mechanisms are mostly rotary mechanisms, ensuring unidirectional rotation while achieving periodic speed variations. The inertial force generated by these speed variations causes the tomatoes to fall. Therefore, varying the speed can be used to achieve different separation effects, while also facilitating continuous operation. This type of machine is most widely used in tomato combine harvesters.

[0103] The specific workflow is as follows:

[0104] 1. The harvested tomato plants (with tomatoes), tomatoes (highly mature and have fallen off the vines), and the mulch / drip tape mixture are transported backward from the primary conveyor belt 1. When passing through the gap between the primary conveyor belt 1 and the secondary conveyor belt 2, the highly mature tomatoes that have separated from the tomato vines fall from here to the fruit belt 9 and continue to be transported backward.

[0105] 2. The tomato plants (with tomatoes) and the mixture of mulch film and drip irrigation tape are continuously transported backward via the secondary conveyor belt 2, wherein the mulch film and drip irrigation tape are 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, separating the tomatoes from the tomato vines. The tomatoes fall from the gaps between the lower stripping fingers 6 onto the fruit belt 9 and continue to be transported backward. The tomato vines slide along the lower stripping fingers 6 onto the vine belt 10 and continue to be transported backward.

[0107] The separation system provided by the utility model 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 fall directly from this gap to the fruit belt 9 without passing through the vibrating roller. This diversion reduces the vibration separation pressure, reduces the risk of blockage, and improves the separation efficiency. At the same time, this part of the tomatoes avoids being beaten by the vibrating rod, reducing the breakage rate.

[0109] 2. Multiple rows of barbed teeth 2-1 are added to the secondary conveyor belt 2 to guide impurities such as the mulch film / drip irrigation tape to the anti-entanglement roller 4. The anti-entanglement roller 4 rotates to wrap the mulch film / drip irrigation tape into the anti-entanglement roller groove 4-1, which is convenient for regular cleaning. The unique barbed teeth can ensure that impurities such as the 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, forming the upper boundary of the tomato plants' movement and preventing them from becoming entangled in the vibrating roller 8. The lower fingers 6 are staggered with long fingers 6-1 and short fingers 6-2. The fingers are densely arranged at the front to prevent the tomato plants from sagging through the gaps between the fingers, which would prevent the vibrating rod 8-1 from working effectively and causing incomplete tomato separation. The fingers are sparsely arranged at the rear, prompting the separated tomatoes to fall quickly. This effectively solves the problem of incomplete separation of tomatoes from tomato vines and low separation efficiency.

[0111] 4. The vibrator 7 primarily consists of three pendulums 7-2 of identical shape and mass. The relative angles of the pendulums 7-2 are maintained constant by a synchronous belt 7-3 and synchronous pulley 7-4. During operation, a hydraulic motor drives the drive wheel 7-5 to rotate. Transmission via the synchronous belt 7-3 causes the pendulums 7-2 to rotate at high speed, generating a periodically varying force. This provides a periodically varying acceleration to the vibrator 7, which is then transmitted to the vibrating roller 8 via the bracket 7-1, ultimately manifesting as the vibration of the vibrating roller 8. During the vibration process, the vibrating rod 8-1 strikes the tomato vines in the channel, causing them to fall off. The tomatoes then fall through the gaps in the lower shedding fingers 6 into the fruit belt. The tomato vines then slide along the lower shedding fingers 6 and fall into the vine belt, achieving fruit and vine separation.

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

[0113] 5. The vibrating roller 8 primarily consists of vibrating rods 8-1. The number of vibrating rods has been increased based on the transmission structure. The original vertical structure has been adjusted to a 15-degree angle, with adjacent rows staggered and stepped. This effectively reduces the vibrating rods' striking angle and minimizes tomato damage. Furthermore, the vibrating rods are made of fiberglass and high-pressure resin, which provides a certain degree of elasticity and reduces tomato damage. Anti-tangling tape 8-2 prevents impurities such as drip irrigation tape and ground film from getting entangled in the gaps between adjacent vibrating rods. Synchronous rubber discs 8-3 are fixed to facilitate maintenance and replacement.

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

[0115] It should be noted that all electronic components involved in the present invention adopt existing technologies, and the above components are electrically connected to the controller, and the control circuits between the controller and the components are existing technologies.
