Description

Technical Field

[0001] The utility model mainly relates to the technical field of agricultural machinery, in particular to a melon harvester. Background Art

[0002] The melon-beating machine is mainly used for harvesting seeds of gourds, melons, seed melons and other melons. It can harvest various melon crops growing on the ground. The working principle of the melon-beating machine is to crush the melons after picking them and then remove the seeds.

[0003] When the melon-beating machine is in operation, multiple mechanisms need to cooperate to complete the picking and seeding of the melons. In the prior art, the overall structural layout of the melon-beating machine is not compact and reasonable enough, and the efficiency of picking and seeding the melons is low and the effect is poor.

[0004] The picking of melons is generally achieved by using the melon-picking mechanism of the cutting table. During the picking process, the melon-picking teeth are inserted into the melons to drive the melon-picking movement. Therefore, some branches and vines are carried along with the melons during the actual picking process. If these branches and vines are not cut off and handled in time, it is easy to affect the subsequent operation efficiency and seed collection effect.

[0005] In the prior art, after the melons are initially crushed, they are sent to a screening structure to separate the melon pulp and the seeds. In the screening structure, only a rotatable stirring shaft is often provided, while the screen is fixed, which leads to low screening efficiency, poor effect, and easy clogging of the screen.

[0036] refer to Figure 1 As shown, it is a schematic diagram of the overall structure of a melon harvester provided in this embodiment.

[0037] The melon harvester of the present embodiment mainly comprises a vehicle body, a cutting platform 1 is arranged at the front of the vehicle body, and a melon collecting mechanism 2 is arranged at the rear of the cutting platform 1.

[0038] The harvesting platform 1 is used to pick the melons on the ground and transport them to the melon collection mechanism 2 at the rear.

[0039] refer to Figure 2 , Figure 3 As shown, the cutting platform 1 includes a vine beating assembly 11, a melon picking assembly 13, a melon stripper 15, a vine pulling assembly 14 and a cutting platform conveyor belt 16. The vine beating assembly 11 is located at the front end, and the main shaft drives multiple swing belts to rotate so that the vines are separated from the melons. Melon separators 12 are provided at both ends of the vine beating assembly 11. The melon separators 12 separate the rows and make the melons on the edge move inward for easy picking. The melon picking assembly 13 is located at the rear of the vine beating assembly 11. The melon picking assembly 13 is mainly driven by the main shaft to rotate the melon picking teeth. During the rotation, the melon picking teeth are inserted into the melons to pick up the melons. At the same time, as the melon picking assembly 13 rotates, the melons are brought to the upper rear part along with the rotation of the main shaft. The melon stripper 15 is located at the upper rear part of the melon picking assembly 13. The melon stripper 15 is composed of a plurality of arc-shaped bars, and the gaps between the bars can allow the melon picking teeth to pass through. When the melons pass through the melon stripper 15, they fall off the melon picking teeth due to the obstruction of the bars and fall into the melon collecting mechanism 12 at the rear.

[0040] In this embodiment, a knife-flinging assembly 21 and a seedling-pulling assembly 14 are provided for cleaning the branches and seedlings carried by the melon-pulling device. Specifically, the knife-flinging assembly 21 is provided at the front lower part of the melon-pulling collection mechanism 2 and is located behind the melon-pulling assembly 13. The knife-flinging assembly 21 is a plurality of groups, which are arranged in sequence and spaced along the axial direction to ensure that the length direction of the melon-pulling assembly 13 can be covered. The knife-flinging assembly 21 is mainly used to cut off the branches and seedlings carried by the melon-pulling device through the blade when the melon-pulling assembly 13 drives the melon-pulling movement to avoid entanglement, and also facilitates the subsequent work of the seedling-pulling assembly 14.

[0041] refer to Figure 4 The structure of the blade-flinging assembly 21 mainly includes a transmission box 211, in which a power shaft 212 and an output shaft are arranged, and both ends of the power shaft 212 extend out of the transmission box 211. The power shaft 212 and the output shaft are connected by bevel gears to achieve reversal, and a blade 213 is installed on the output shaft. The power shaft 212 is arranged to have both ends extending in order to connect the blade-flinging assemblies 21 together and rotate synchronously. The power shafts 212 of the blade-flinging assemblies 21 are connected by couplings, and the power shaft 212 of the outermost blade-flinging assembly 21 is connected to the driving sprocket. When the blade 213 rotates, the branches and seedlings can be cut off to avoid entanglement of the branches and seedlings.

[0042] Figure 2 The seedling pushing assembly 14 shown in the figure is located above the melon stripping device 15, and the cutting table conveyor belt 16 is located in front of the seedling pushing assembly 14. The seedling pushing assembly 14 is composed of a main shaft and a plurality of shifting plates installed on the main shaft. The structural design of the melon stripping device 15 allows some branches and seedlings to move to the top of the melon stripping device 15 along with the melon picking teeth during melon stripping. At this time, the branches and seedlings can be pushed to the cutting table conveyor belt 16 in front by rotating the shifting plates and discharged through the cutting table conveyor belt 16.

[0043] The beaten melon collection mechanism 2 of the present embodiment mainly comprises a collection bin and an auger arranged in the bin. The beaten melons dropped from the melon remover 15 roll into the collection bin and are transported to the conveying trough 3 by the auger.

[0044] The conveying trough 3 is arranged obliquely behind the beaten melon collection mechanism 2. The conveying trough 3 passes under the vehicle cab and is used to convey the beaten melons backward to the feeding mechanism 4.

[0045] The feeding mechanism 4 of this embodiment refers to Figure 5 As shown, a feed box is included, the bottom of which is an inclined surface adapted to the conveying trough 3 in order to save space. A melon cutting shaft and a melon pressing shaft are provided inside the feed mechanism 4 for preliminary cutting of the melons, which are then fed to the screening mechanism 5 through the outlet at the bottom.

[0046] refer to Figure 6As shown, the screening mechanism 5 is located below the feeding mechanism 4, and it includes two sets, working together. The screening mechanism 5 includes a rotating screen 51 (the steel ring of the rotating screen 51 in the figure only shows a partial structure, and the rotating screen 51 can also adopt a fish scale screen cylinder structure), a screening and stirring shaft 52 is arranged inside the rotating screen 51, and a screening and discharging auger 53 is arranged below the rotating screen 51. In this embodiment, the rotating screen 51 and the screening and stirring shaft 52 rotate synchronously and in opposite directions. Through the relatively rotating rotating screen 51 and the screening and stirring shaft 52, the crushed melons can be further crushed when entering the rotating screen 51, so that the melon pulp and melon seeds are separated, and then fall through the holes or gaps on the rotating screen 51 to the screening and discharging auger 53 below, and are transported to the cleaning mechanism 6 through the screening and discharging auger 53.

[0047] In the above structure, a large gear ring 55 is provided on the outer ring of one end of the rotary screen 51, a power sprocket is provided at one end of the screening and stirring shaft 52, and an intermediate sprocket 58 is provided at the other end. The intermediate sprocket 58 is connected to the transition sprocket 57 through a chain. The transition sprocket 57 is coaxially arranged with the pinion 56, and the pinion 56 is meshed with the large gear ring 55. This structure enables the screening and stirring shaft 52 to drive the intermediate sprocket 58 to rotate when it rotates, and finally drives the pinion 56 to rotate, and drives the large gear ring 55 to rotate through the pinion 56, thereby driving the rotary screen 51 to rotate. In order to ensure the stability of the movement of the rotary screen 51, a tugboat 54 can be provided to support the rotary screen 51.

[0048] In this embodiment, a cleaning mechanism 6 is arranged on the outside of each screening mechanism 5. The cleaning mechanism 6 mainly includes a cylinder and an auger. The cylinder has an opening for the pulp liquid to flow out and only the melon seeds remain in the cylinder. The seeds are transported to the transverse conveying mechanism 7 by the auger. Finally, the melon seeds cleaned by the cleaning mechanisms 6 on both sides are transported to the vertical conveying mechanism 8 through the transverse conveying mechanism 7. A silo 9 is arranged on one side of the vertical conveying mechanism 8, and the vertical conveying mechanism 8 is used to transport the melon seeds to the silo 9.
