Description

Technical Field

[0001] This invention belongs to the field of jujube harvesting machine technology, and in particular relates to a jujube harvesting head for a jujube harvester and a jujube harvester constructed therefrom. Background Technology

[0002] The traditional method of harvesting jujubes is to collect them after they fall to the ground. Specifically, after the jujubes ripen, they naturally dry on the tree. At this time, external disturbances cause a large number of jujubes to fall. The jujubes are then knocked down to the ground and collected by a jujube harvesting machine. Most existing jujube harvesting machines use a wind-powered system to create negative pressure, which allows the suction head on the suction pipe to suck up the jujubes from the ground. This method has low collection efficiency. Furthermore, during the suction process, a large amount of debris such as leaves, branches, roots, and stones are sucked in. These debris needs to be separated later by a separation device. During separation, the jujubes impact the separation mechanism under the suction force, which can damage some of the jujubes. Moreover, this separation method can only separate large particles of debris; some small particles still mix with the jujubes and enter the harvesting basket, resulting in incomplete cleaning. Therefore, improvements are necessary. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the existing technology by providing a jujube harvesting head for a jujube harvester and a jujube harvester composed therefrom, which has the characteristics of effectively cleaning up the debris mixed in the jujubes, making the collected jujubes cleaner, and effectively improving the collection efficiency.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a jujube harvesting head for a jujube harvester, which includes a head support and a wind system, wherein the head support is provided with a first blower mechanism, a second blower mechanism, a separation mechanism, a third blower mechanism and a jujube collecting mechanism; The wind power system is connected to the first air blowing mechanism, the second air blowing mechanism and the third air blowing mechanism respectively and provides air power to them respectively; The first blower is mounted at the front end of the head bracket and is used to clean up light debris on the ground; The second blower mechanism is located behind the first blower mechanism and below the separation mechanism, and is used to loosen the dates and debris on the ground. The separation mechanism has a drive chain, separation claws, and separation baffles. The drive chain reciprocates during operation. The separation claws are fixedly arranged on the drive chain and move together with it. The separation claws are used to grab long strip-shaped debris on the ground and place the grabbed long strip-shaped debris on the drive chain. The separation baffles work in conjunction with the separation claws to separate the long strip-shaped debris to the outside of the machine head support. The air outlet on the third blower mechanism is positioned opposite the jujube collecting mechanism, and is used to apply airflow to make the jujubes on the ground roll onto the jujube collecting mechanism; The jujube collecting mechanism is used to collect jujubes that are rolled over by the wind force of the third blower mechanism.

The jujube collecting head separates debris from the ground through its first blower mechanism, second blower mechanism and separation mechanism, and uses the third blower mechanism to roll the jujubes on the ground onto the jujube collecting mechanism. The jujube collecting frame is connected to the outer frame and moves synchronously with it; the jujube transporting mechanism is connected to the jujube collecting mechanism to transport the jujubes into the jujube collecting frame.

[0018] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention. The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] See the example. Figures 2 to 3 The image shows a jujube harvesting head for a jujube harvester, comprising a head support 10 and a wind power system. The wind power system is a fan capable of providing high-volume airflow, connected to various blower mechanisms via air ducts to provide airflow to the blower mechanisms. The fan is concealed inside the outer frame 50 to avoid external interference. The bottom of the head support 10 has a skid 11, which allows for smoother movement of the head support 10 on the ground. The head support 10 is equipped with a first blower mechanism, a second blower mechanism, a separation mechanism, a third blower mechanism, and a jujube collecting mechanism.

[0020] The first blower mechanism is located at the front end of the head support 10 and is used to clean up light debris on the ground. Specifically, the first blower mechanism consists of an air supply pipe 30 and a fan cover 31. The air supply pipe 30 is connected to the air duct of the wind power system and has two air outlets in opposite positions. The fan cover 31 is located on the air outlets and has a certain tilt angle relative to the ground, which is generally between 30° and 45°. During operation, the air is blown out from the fan cover 31, which can blow away some light debris on the ground, such as leaves and weeds.

[0021] The second blower mechanism is located behind the first blower mechanism and below the separation mechanism. It is used to loosen the dates and debris on the ground. Specifically, the second blower mechanism includes an air supply pipe 32 and an air outlet 33. One end of the air supply pipe 32 is connected to the air duct on the wind power system, and the other end is connected to the air outlet 33. The air outlet 33 is located at the bottom side of the head support 10. The air outlet 33 blows air to loosen the ground and can also carry away some small stones and mud on the ground.

[0022] The separation mechanism includes a transmission chain 20, a separation claw 21, a separation baffle 22, and a separation roller 23. The two ends of the transmission chain 20 are respectively sleeved on the separation roller 23. Driven by the separation roller 23, it will reciprocate during operation. The transmission chain 20 has transmission rods 25 arranged at equal intervals. The distance between the transmission rods 25 is greater than the long diameter of the jujube, so that the jujube can fall back to the ground from the distance after being grabbed by the separation claw 21. Separating claws 21 are typically arranged in groups of three to six, with the number determined by the width of the transmission chain 20, usually in groups of four or five. They are sequentially and fixedly arranged on the transmission chain 20 and move in tandem with it. Separating baffles 22 are located on the machine head support 10, and to save space, they are generally fixed to the skids 11 of the machine head support 10. During use, the separating baffles 22 and separating claws 21 work together, with the separating claws 22 passing through the gaps between them during movement. When the separating claws 21 grab long, narrow objects (such as branches or long roots) on the ground, they are transmitted through the transmission chain 20 to the separating baffles 22, where they break due to the combined force and fall outside the machine head support 10. Simultaneously, the separating claws 21 also loosen the soil upon contact with the ground. To prevent the tips of the separating claws 21 from damaging the jujubes, a soft rubber sleeve is wrapped around the front end of the separating claws 21. The top of the machine head support 10 has an air outlet 24 connected to the wind system. The air outlet 24 is located above the transmission rod 25, and its airflow can be transmitted to the transmission rod 25 to make it easier for the dates to fall from the gaps between the transmission rods 25. It should be noted that the separating roller 23 can obtain power directly by connecting to the drive motor to drive the conveyor chain 20 to rotate, or the ends of the separating roller 23 and the ends of the rotating shaft of the date collecting turntable 41 can be set as gear structures so that they mesh with each other, and the rotation of the rotating shaft drives the separating roller 23 to rotate.

[0023] The air outlet of the third blower mechanism is positioned opposite the jujube collecting mechanism, and is used to apply airflow to make the jujubes on the ground roll onto the jujube collecting mechanism. The third blower mechanism includes an air supply duct 34, an air supply box 35, and an air regulating plate 36. One end of the air supply duct 34 is connected to the air duct on the wind power system, and the other end is connected to the air supply box 35. The four sides of the air supply box 35 are sealed, and the top is covered by a cover plate 39. An air supply outlet 37 is opened at the bottom. The air regulating plate 36 and the bottom surface of the air supply box 35 form an air outlet 38. The air outlet 38 and the air supply outlet 37 are connected. 7 is connected and positioned opposite to the jujube collecting plate 40 on the jujube collecting mechanism; the air regulating plate 36 is a rotatable structure. Specifically, the rear end of the air regulating plate 36 is hinged to the bottom of the air supply box 35, and its upper end face has a fixed seat 361. A hook 362 is connected to the fixed seat 361. There is a through-hole on the cover plate. The upper end of the hook 362 extends through the air outlet 38 and the through-hole of the cover plate 39 to the outside of the air supply box 35. The upper end of the hook 362 is a threaded part, and an adjusting ball 363 is screwed onto the threaded part. The lower part of the adjusting ball 362 contacts the cover plate 39. When it is necessary to reduce the opening of air outlet 38, the hook 362 is moved upward by rotating the adjusting ball 363. This movement causes the air regulating plate 36 to rotate upward, thus reducing the opening of air outlet 38. When it is necessary to increase the opening of air outlet 38, the hook 362 is moved downward by rotating the adjusting ball 363 in the opposite direction. This movement causes the air regulating plate 36 to rotate downward, thus increasing the opening of air outlet 38.

[0024] The jujube collecting mechanism is used to collect jujubes that are blown by the airflow from the third blower mechanism. The mechanism includes a collecting plate 40, a collecting turntable 41, and a collecting motor. The collecting plate 40 is located at the bottom of the machine head support 10. The collecting motor is connected to the collecting turntable 41 and can drive it to rotate. The collecting turntable 41 has rotating plates 42 distributed on it. The rotating plates 42 work in conjunction with the collecting plate 40 to collect the jujubes on the collecting plate 40. During operation, under the force of the airflow from the third blower 38, the jujubes roll onto the collecting plate 40. When the rotating plate 42 rotates to the position of the collecting plate 40, it carries away the jujubes from the collecting plate 40 and temporarily stores them in the jujube storage chamber formed by the rotating plate 42 and the inner wall of the collecting turntable 41. When the rotating plate 42 rotates to the falling section, the jujubes automatically fall onto the jujube transport mechanism of the jujube harvester.

[0025] See Figures 1 to 4 A jujube harvester includes an outer frame 50 and a jujube harvester head powered by a drive mechanism, an operating table, a jujube transport mechanism, a walking mechanism 52, a jujube collection frame 53, and a lifting mechanism. The operating table is located inside the outer frame 50 and is used to control the movement of the walking mechanism 52, control the jujube harvester head to perform jujube harvesting operations, control the jujube transport mechanism to transport the jujubes into the jujube collection frame 53, and control the lifting mechanism to lift the jujube harvester head.

[0026] The walking mechanism 52 is a tracked chassis, and the bottom of the outer frame 50 is fixedly connected to the tracked chassis. The walking mechanism is driven by the tracked chassis, which makes the movement more stable.

[0027] The jujube harvester head separates debris from the ground through its first blower mechanism, second blower mechanism, and separation mechanism, and uses the third blower mechanism to roll the jujubes on the ground onto the jujube collection mechanism.

[0028] The jujube transport mechanism comprises a first conveying device 70 and a second conveying device 71. The first conveying device includes a conveyor cover 701, a first drive motor, a conveyor belt 702, a first conveyor roller 703, and a conveyor plate 704. Both ends of the conveyor belt 702 are respectively fitted onto the first conveyor roller 703, which is positioned at both ends of the conveyor cover 701. The drive motor is connected to the first conveyor roller 703 to drive its rotation. The conveyor plate 704 is mounted on the conveyor belt 702 and cooperates with the jujube collection mechanism to transport the jujubes; that is, jujubes falling from the turntable 42 will fall onto the conveyor plate 704. The jujube-felling opening 705 of the conveyor cover 701 has an exhaust vent 706, which is connected to a wind system to blow away dust falling from the jujube-felling opening 705 and adhering to the surface of the jujubes. The second conveying device 71 includes a second drive motor, a conveying chain 711, a second conveying roller 712, a conveying rod 713, and a side baffle 714. The second conveying roller 712 is respectively disposed at both ends of the side baffle 714. The second drive motor is connected to the second conveying roller 712 and controls its rotation. The two ends of the conveying chain 711 are respectively sleeved on the second conveying roller 712. The conveying rod 713 is arranged on the conveying chain 711 to form a date feeding channel. The date feeding channel has an inlet located directly below the date outlet 705 of the first conveying device 70, and its outlet located directly above the date receiving frame 53. In this way, the dates transported to the date outlet will automatically fall into the date receiving frame 53 under the drive of the conveying rod 713.

[0029] The jujube collecting frame 53 is connected to the outer frame 50 and moves synchronously with it. Specifically, the front end of the jujube collecting frame 53 is fixed to the outer frame 50 through a connecting seat, and its bottom has rollers. When the outer frame 50 moves, the jujube collecting frame 53 will move together.

[0030] The lifting mechanism includes a lifting frame 60, a lifting seat 61, and a lifting cylinder 62. The lifting frame 60 is fixedly connected to the outer frame 50. The lifting cylinder 62 is installed inside the lifting frame 60, and its cylinder rod is connected to the lifting seat 61. The lifting seat 61 is connected to the head support 10 to control the up and down lifting of the jujube harvesting head. In use, the height of the jujube harvesting head can be adjusted by adjusting the lifting seat 61, so as to make better movement after the jujube harvesting work is completed.

[0031] The walking mechanism 52 is now widely used. Its other structures and principles are the same as those of existing technologies, so they will not be described in detail here.
