Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and particularly to a lotus root conveying device and a lotus root digging machine thereof. Background Art

[0002] In agricultural production, lotus root, as an important aquatic economic crop, has special requirements for mechanized operation in its harvesting process. Lotus root production involves multiple links, including tillage of planting fields, planting of lotus roots, field management, and harvesting of lotus roots. Among them, the difficulty of lotus root harvesting has always restricted the further development of the lotus root industry. For a long time, lotus root farmers have mainly relied on manual or mechanical digging for lotus root harvesting, and then manually collect, transport, and clean the lotus roots floating on the water surface. Such traditional processing methods are inefficient and have numerous procedures.

[0003] With the development of agricultural mechanization, equipment such as lotus root digging machines has gradually been applied to lotus root harvesting. However, existing devices still have significant deficiencies in aspects such as adaptability to complex terrains, cleaning efficiency, and automation level.

[0004] The conveying devices of existing lotus root digging machines generally adopt wheeled or tracked moving mechanisms, which are prone to problems such as slipping and vehicle sinking in complex terrains such as lotus root pond sludge and shallow water areas. In addition, the soil and impurities attached to the surface of lotus roots usually need to be manually cleaned a second time. Existing cleaning devices mostly adopt single water washing or simple drum friction, and have poor cleaning effects on stubborn dirt in grooves and gaps, and cause serious waste of water resources. At the same time, the power systems of traditional conveying devices are scattered, and functional modules such as cleaning and transportation lack coordinated drive design, resulting in high energy consumption and high maintenance costs.

A rear conveyor belt 7 is connected between the front roller 23 and the rear roller 25.

[0024] A rear conveyor belt 7 is provided between two groups of vertical plates 6 on the frame 1. A collection box 5 is provided at the rear part of the frame 1, and the collection box 5 is located at the lower rear of the rear conveyor belt 7.

[0025] A driving unit for simultaneously driving the front conveyor belt 13 and the rear conveyor belt 7 is provided on the corresponding upright frame 21. The driving unit includes a second servo motor 8 fixed on the corresponding upright frame 21, a driving gear 36 fixed after the second motor shaft 37 at the output end of the second servo motor 8 extends into the corresponding upright frame 21, a driven gear 38 and a first side belt pulley 45 fixed after one end of a driving rotating shaft 39 extends into the corresponding upright frame 21, and a second side belt pulley 43 fixed by a connecting shaft 42 after one end of the front roller 23 penetrates through the corresponding vertical plate 6; The driving gear 36 meshes with the driven gear 38, and the first side belt pulley 45 is connected to the second side belt pulley 43 by a first side belt 44.

[0027] Moreover, the front conveyor belt 13 drives the roller cleaning assembly through the side drive assembly to clean the lotus roots. The side drive assembly includes a first side gear 53 and a third side pulley 65 fixed after the first cleaning roller shaft penetrates and extends out of the funnel 15, a second side gear 56 fixed after the second cleaning roller shaft penetrates and extends out of the funnel 15, a fourth side pulley 55 fixed after the driven rotating shaft penetrates and extends out of the rotating frame 18, a third side gear 60 and a fifth side pulley 57 installed on the side of the funnel 15 by a movable pin shaft 66, and a drive shaft 51 arranged in the middle of the water collecting cylinder 14. A second side belt 54 is connected between the third side pulley 65 and the fourth side pulley 55, the first side gear 53 meshes with the second side gear 56, and the second side gear 56 meshes with the third side gear 60. A sixth side pulley 58 is fixed after the drive shaft 51 extends out of the water collecting cylinder 14, and a third side belt 59 is connected between the fifth side pulley 57 and the sixth side pulley 58. The spiral blade 40 is fixed on the drive shaft 51.

[0028] The first side gear 53 and the second side gear 56 have the same size, so that the first cleaning roller 17 and the second cleaning roller 16 rotate at the same speed. The second side gear 56 is larger than the third side gear 60 in size, and the fifth side pulley 57 is larger than the sixth side pulley 58 in size, so that the drive shaft 51 can drive the spiral blade 40 to rotate at a high speed, thereby increasing the force of the water flow sprayed by the nozzle 48.

[0029] At the same time, the side drive assembly drives the spiral blade 40 in the water collecting cylinder 14 to rotate, so that the water flow sprayed by the jet water flow cleaning pipe 12 cleans the lotus roots on the front conveyor belt 13.

[0030] The water collecting cylinder 14 is fixed to the side of the corresponding rotating frame 18 by a fixing frame 50, and a bearing seat 64 is further provided on the fixing frame 50, and a bearing sleeved on the drive shaft 51 is provided in the bearing seat 64.

The outer side end of the water collecting cylinder 14 is communicated with the jet water flow cleaning pipe 12 by a water guide pipe 49.

[0031] In addition, to achieve the above object, the present invention further provides a lotus root digging machine, including the lotus root conveying device described above.

[0032] Specifically, when in use, the first servo motor 22 fixed on the corresponding bracket 4 at the front is used as the power source. The first motor shaft at the output end of the first servo motor 22 is connected to the first top pulley 31. Through the transmission of the first top pulley 31, the second top pulley 34, the intermediate pulley 29, and the bottom pulley 33, as well as the first belt 27, the second belt 30, and the third belt 32, the bottom rotating shaft 19 is driven to rotate synchronously, and then the spiral walking blade 3 fixed on the bottom rotating shaft 19 rotates to realize the walking of the device on the lotus pond sludge; After the lotus root conveying device enters the water surface of the lotus pond, the floating drum 2 is stably installed at the bottom of the frame 1, so that the device has good floating stability on the water surface, ensuring that the overall performance of the device will not be affected by the shaking or displacement of the floating drum 2 during the movement and operation; At this time, the spiral walking blade 3 rotates, enabling the lotus root conveying device to move on the water surface of the lotus pond; By the telescopic movement of the hydraulic cylinder 9, the rotating frame 18 is pushed to rotate around the active rotating shaft 39, realizing the rotation of the rotating frame assembly to adjust the angles of components such as the front conveyor belt 13. Until the funnel 15 moves upward from the water and collects the lotus roots floating on the water surface in the funnel 15, then, the second servo motor 8 on the corresponding vertical frame 21 is used as the power. The second motor shaft 37 at the output end of the second servo motor 8 fixedly drives the driving gear 36, and the driving gear 36 meshes with the driven gear 38 on the active rotating shaft 39 to drive the active rotating shaft 39 to rotate, thereby driving the front conveyor belt 13 to operate; Meanwhile, the first side pulley 45 on the active rotating shaft 39 is connected to the second side pulley 43 on the front roller 23 through the first side belt 44 to drive the rear conveyor belt 7 to operate, realizing the front and rear transmission of the lotus roots.

[0033] When the front conveyor belt 13 operates, the side driving assembly drives the roller cleaning assembly to work. The fourth side pulley 55 on the driven rotating shaft is connected to the third side pulley 65 on the first cleaning roller shaft through the second side belt 54 to drive the first cleaning roller 17 to rotate. The first side gear 53 on the first cleaning roller 17 meshes with the second side gear 56 on the second cleaning roller 16 to drive the second cleaning roller 16 to rotate. The second rubber protrusions 61 on the surfaces of the first cleaning roller 17 and the second cleaning roller 16 are used to initially clean the lotus roots, and the initially cleaned lotus roots fall onto the front conveyor belt 13; (as Figure 13 shown, both the front conveyor belt 13 and the rear conveyor belt 7 rotate clockwise, the first cleaning roller 17 rotates clockwise, and the second cleaning roller 16 rotates counterclockwise).

[0034] When the first cleaning roller 17 and the second cleaning roller 16 are initially cleaning the lotus roots, the hydraulic cylinder 9 works, which can cause the funnel 15 to be repeatedly lifted and lowered, and thus the lotus roots in the funnel 15 can repeatedly enter and exit the water surface, so as to use the pond water in the lotus pond to repeatedly clean the lotus roots; At the same time, the side driving assembly also drives the spiral blade 40 in the water collecting cylinder 14 to rotate. The inner side end of the water collecting cylinder 14 is open. Under the rotation of the spiral blade 40, the water is squeezed into the water guide pipe 49 through the inner side end of the water collecting cylinder 14, and the water in the water collecting cylinder 14 is transported to the jet water cleaning pipe 12 through the water guide pipe 49, and then the water is sprayed out by the nozzle 48 to further clean the lotus roots on the front conveyor belt 13.

[0035] The cleaned lotus roots are transported to the rear conveyor belt 7 through the front conveyor belt 13 and finally fall into the collection box 5 at the rear of the frame 1 for collection.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention.
