Description

Technical Field

[0001] This invention relates to the field of pineapple harvesting equipment, and in particular to a self-propelled clamping and breaking pineapple harvester. Background Technology

[0002] Pineapple, a tropical fruit, is widely cultivated in nearly 70 countries and regions due to its unique taste and nutritional value, accounting for approximately 5% of the world's annual fruit production. While agricultural machinery has been widely adopted in the cultivation of various fruits and crops, pineapple harvesting remains primarily manual. Farmers use knives to cut the pineapples one by one, picking the ripe fruit and placing them in baskets they carry or transporting them to designated locations. This is because pineapples are mainly grown in mountainous and hilly areas with complex terrain and rugged roads. Furthermore, pineapple harvesting is highly seasonal, with a harvest period of only about two weeks. Currently, apart from a few orchards equipped with semi-mechanized auxiliary devices, manual harvesting is the primary method. The labor required for the entire harvesting operation accounts for 40% of the total pineapple production cost in the short term. Researching and developing pineapple harvesting machinery and equipment is crucial for alleviating labor shortages, stabilizing harvesting quality, reducing labor intensity, lowering operating costs, and improving harvesting efficiency. Therefore, designing a self-propelled clamping and breaking pineapple harvester to achieve mechanized pineapple harvesting is of great significance. Summary of the Invention

[0038] In this embodiment, the walking device 6 is a tracked walking mechanism, which is driven by a walking motor.

[0039] This embodiment of a self-propelled clamping and breaking pineapple harvester employs two sets of harvesting units, designed for two rows of planted pineapples. During harvesting, both rows of pineapples are harvested simultaneously. During operation, the tracked walking mechanism is located on both sides of the two rows of pineapples. The walking mechanism is controlled by a walking motor, so that the two sets of harvesting units of the harvesting device are respectively positioned above the two rows of planted pineapples, thereby achieving simultaneous harvesting of the two rows of pineapples.

[0040] The working process of this self-propelled clamping and breaking pineapple harvester is as follows:

[0041] (1) Control the harvester to walk in the pineapple field by the walking motor, walk to the starting point of pineapple harvesting, and at the same time control the position of the tracked walking mechanism so that the tracked walking mechanism is located on both sides of the two rows of pineapples planted.

[0042] (2) Control the telescopic electric cylinder to drive the picking installation plate to rise and fall, thereby adjusting the picking height so that the stem below the pineapple fruit is located in the passage of the picking rack.

[0043] (3) Start the main transmission motors of the two picking units, and drive the main conveyor belt to move through the first sprocket chain transmission mechanism; start the swing motors of the two picking units, and drive the picking units to swing left and right through the crank connecting rod assembly;

[0044] (4) Control the walking motor to make the tracked walking mechanism move forward; when the picking unit approaches the pineapple fruit, the pineapple stem enters the channel under the action of the flared mouth. At the same time, the pineapple fruit will enter between the main conveyor belt and the auxiliary conveyor belt. The pineapple fruit will squeeze the auxiliary conveyor belt, so that the auxiliary conveyor belt moves to the appropriate position under the combined action of the pineapple fruit and the spring; while the pineapple fruit is conveyed backward by the main conveyor belt, and with the cooperation of the main conveyor belt and the auxiliary conveyor belt, it is clamped and conveyed backward; during this process, when the picking unit sways left and right, the pineapple stem is broken, realizing the picking of the pineapple fruit; the picked pineapple fruit continues to be conveyed backward by the main conveyor belt and the auxiliary conveyor belt.

[0045] (5) The horizontal conveying device receives the pineapple fruits picked by the picking device and, under the restriction of the baffle, conveys them backward to the lifting conveying device; the lifting conveying device lifts the pineapple fruits under the action of the partition and conveys them to the collecting device.

[0046] (6) The harvester moves forward continuously to achieve continuous harvesting of pineapples; when the collection device is full, control the harvester to reach the designated unloading location, open the back door of the collection box, unload the harvested pineapple fruits, and continue the pineapple harvesting operation after unloading.

[0047] (7) After the pineapple harvesting operation is completed, turn off the main conveyor motor and control the telescopic electric cylinder to reset; then control the harvester to leave the pineapple field to complete the work.

[0048] This embodiment of a self-propelled clamping and breaking pineapple harvester uses a main conveyor belt and a secondary conveyor belt to clamp the pineapple, and the left and right swaying of the swing mechanism causes the stem at the lower end of the pineapple fruit to break, thus harvesting the pineapple; it can solve the problem of time-consuming and labor-intensive manual harvesting of pineapples.

[0049] This embodiment of a self-propelled clamping and breaking pineapple harvester can meet the mechanized harvesting needs of pineapples in different parts of the field, greatly reducing labor intensity and improving the efficiency of pineapple harvesting.
