Description

[0002] Lotus root is an important aquatic vegetable in China, with high economic benefits, wide planting area and broad industrial prospects. However, due to its harsh growth environment, easy to break and no obvious distribution pattern under the mud, it is difficult to harvest mechanically. At present, it mainly relies on manual harvesting, but the high cost, high labor intensity and high dependence on personnel proficiency of manual harvesting have limited the development of the lotus root industry.

[0003] At present, the lotus root harvester used in the prior art can be applied to the mechanized harvesting of lotus roots. The main working principle of the lotus root harvester is to flush the soil around the lotus root with a high-pressure water gun, so that the lotus root floats to the surface for easy collection. Specifically, the high-pressure water pump in the machine generates a strong water flow, which is sprayed onto the soil around the lotus root through a high-pressure nozzle, flushing the soil away, separating the lotus root from the soil, and then floating to the surface.

[0050] See also Figure 1-9 The present invention provides a technical solution: the adaptive lotus root harvester of the present invention mainly includes a crawler walking device 1, a load-bearing plate 2, a jet device 3, a double-chain transmission connecting rod device 4, an auxiliary lifting device 5, a conveying device 6, a cleaning device 7, a storage box 8, and a debris barrier net 9.

[0051] The walking device 1 is mainly composed of a base 1-1, a traveling motor 1-2, a driving wheel 1-3, a driven wheel 1-4, a tensioning wheel 1-5, a crawler track 1-6, and a shaping plate 1-7. A load-bearing plate 2 is welded on the base 1-1 to provide support. The driving wheel 1-3 is coaxially connected to the traveling motor 1-2 on the base. The driving wheel 1-3, the driven wheel 1-4 and the tensioning wheel 1-5 are connected to the shaping plate 1-7 bolted to both sides of the base 1-1. The crawler track 1-6 is meshed and connected with the tensioning wheel 1-5, the driving wheel 1-3 and the driven wheel 1-4 respectively. A double-row roller chain crawler track is adopted, and the driving wheel 1-3 and the driven wheel 1-4 are wound with the crawler track 1-6 to realize the movement and steering of the lotus root digger. The double-row roller chain crawler track of the present invention uses four driving forces, can pass through any road conditions in all terrains, and is more suitable for walking in the complex environment of lotus ponds.

[0052] like Figure 1As shown, the jet device 3 is connected to the front end of the load-bearing plate 2, and the multi-hole row nozzle 3-3 is controlled by the hydraulic adjustment rod 3-2 to be lowered and inserted into the mud layer. The debris blocking net 9 is preferably made of plastic. The debris blocking net 9 is welded to the column on the load-bearing plate 2 and is located above the jet device 3. It can block water plants, garbage, etc. floating on the surface of the lotus field. It can enclose a space for the floating lotus roots during harvesting, which is conducive to the interference-free operation of the double-chain transmission connecting rod device 4 and the auxiliary lifting device 5 to avoid interference from external factors. The double-chain transmission connecting rod device 4 and the auxiliary lifting device 5 then cooperate to fish out the lotus roots and send them to the self-rotating connecting rod 3-4 of the conveying device 3. The lotus roots are transported by the conveyor belt 6-3 and sent to the storage box 2 after being cleaned by the cleaning device 7 welded to the connecting rod bracket 6-5, so as to realize the collection, cleaning and storage of lotus roots. The storage box 8 is located at the rear end of the lotus root digging machine and is fixed to the lifting regulator 6-2 by buckles.

[0053] Specifically, the jet device 3 is mainly composed of a fixed plate 3-1, a hydraulic adjustment rod 3-2, a multi-hole row nozzle 3-3, a water pipe a3-4, a diverter 3-5, a hydraulic pump 3-6 and a water pump a3-7.

[0054] Among them, as a further improvement, the hydraulic adjustment rod 3-2 is hingedly installed on the fixed plate 3-1, and the fixed plate 3-1 is welded on the load-bearing plate 2; the connecting rod assembly 3-8 is also hingedly installed on the fixed plate 3-1, and the hydraulic adjustment rod 3-2 is connected to the hydraulic pump 3-6. Multiple groups of the hydraulic adjustment rods 3-2 drive the movable part of the connecting rod assembly 3-8, and the multi-hole row nozzle 3-3 is installed at the output part of the connecting rod assembly 3-8. The hydraulic pump 3-6 is used to control the extension and retraction of the hydraulic adjustment rod 3-2. Since multiple hydraulic adjustment rods 3-2 are set, the upper and lower heights and angles of the connecting rod assembly 3-8 can be adjusted, and the multi-hole row nozzle 3-3 can be raised and lowered accordingly to loosen the deep soil.

[0055] In a further scheme, the multi-porous row nozzle 3-3 is a plate-like shovel-shaped structure, and the spray hole of the nozzle is arranged at the bottom outer end of the shovel-shaped structure. This structure is firstly easier to insert into the mud of the lotus pond, and the structural strength can be guaranteed. It is not easy to bend and break during the stress process. When the shovel-shaped structure of the nozzle is inserted into the mud, water is sprayed, which can flush out the mud around the lotus root, thereby making the lotus root float.

[0056] The double-chain drive connecting rod device mainly consists of a bracket 4-1, a gear 4-2, a drive chain a 4-3, a lifting connecting rod 4-4, and a linkage buckle 4-5. The auxiliary lifting device mainly consists of a "Lv"-shaped bracket 5-1, a wedge-shaped cushion block 5-2, and a drive chain 5-3. The bracket 4-1 is connected to 4 drive motors by screws and is coaxially connected to 4 gears 4-2 respectively. The upper and lower gears 4-2 form a group and mesh with the drive chain a 4-3. The holes on both sides of the lifting connecting rod 4-4 are coaxially connected to the linkage buckle 4-5 by bolts. The linkage buckle 4-5 is respectively fixed to the same position of the left and right drive chains a 4-3 by buckling. The tail of the lifting connecting rod 4-4 is placed on the wedge-shaped cushion block 5-2 to ensure that the harvested lotus roots will not fall. Four shaft-end connecting gears are installed on the "Lv"-shaped bracket 5-1 and mesh with the drive chain 5-3. The upper and lower gears form a group, and the lower gear is coaxially connected to the drive motor. The wedge-shaped cushion block 5-2 is buckled and connected to the drive chain 5-3.

[0057] The transmission device 6 mainly consists of a turbo screw rod lifting mechanism 6-1, a lifting regulator 6-2, a conveyor belt 6-3, a connecting rod 6-4, a connecting rod bracket 6-5, a drive chain c 6-6, a transmission wheel 6-7, a load-bearing triangular bearing 6-8, and a sensor 6-9. Interleaved transmission gears are installed on the connecting rod 6-4 for the drive chain c 6-6 to mesh. Two of the transmission wheels 6-7 are coaxially connected to independent motors to make the connecting rod 6-4 spin. A load-bearing triangular bearing 6-8 is provided below the spinning connecting rod 6-4, which is welded to the connecting rod bracket 6-5 to improve the load-bearing capacity of the connecting rod 6-4. The turbo screw rod lifting mechanism 6-1 is placed on the load-bearing plate 2 on both sides of the conveyor belt 6-3 and is connected to the lifting regulator 6-2, while the connecting rod bracket 6-5 is welded to the lifting regulator 6-2. Thus, the turbo screw rod lifting mechanism 6-1 can receive the signal from the sensor 6-9 to control the lifting of the entire collection platform so that it is 5 cm above the water surface.

[0058] The cleaning device 7 includes a fixed bracket 7-1, a sprayer 7-2, a water pipe b 7-3, and a water pump b 7-4. The fixed bracket 7-1 is welded to the sprayer 7-2 and the lifting regulator 6-2 respectively. The sprayer 7-2 is connected to the water pump b 7-4 inside the base through the water pipe b 7-3.

[0059] Combined with the above examples, the working principle of the adaptive lotus root harvesting machine of the present invention is briefly described as follows:

[0060] When the lotus root digger enters the working area, the turbine screw lifting mechanism 6-1 receives the signal from the sensor 6-9 to control the transmission platform to be 5 cm above the water surface, and the hydraulic pump 3-6 drives the hydraulic adjustment rod 3-2 to lower the multi-hole row nozzle 3-3 into the mud layer. The water pump a3-7 absorbs water through the water pipe a3-4 to the diverter 3-5 and then transmits water to the multi-hole row nozzle 3-3 through the water pipe a3-4, spraying high-pressure water to disperse the mud layer. When the lotus root digger moves forward, the multi-hole row nozzle 3-3 acts as a shovel to loosen the deeper mud layer, making it easier for the lotus root to float. The lotus root floats to the working area of ​​the lotus root digging machine harvesting device, and the driving motor controls the gear 4-2 to rotate. The transmission chain a4-3 engages with it to transmit the lifting link 4-4 to make an elliptical motion to pick up the lotus root on the water surface. The wedge-shaped pad 5-2 holds the lifting link 4-4 to prevent the lotus root from falling easily. As the lifting link 4-4 enters the transmission area, it intersects with the spinning link 6-4 during movement, leaving the lotus root on the spinning link 6-4. The lotus root is sent to the conveyor belt 6-3 by its spinning motion, and the water pump b7-4 absorbs water and transports it to the sprinkler 7-2 through the water pipe b7-3 to flow out and flush the lotus root. After cleaning and pretreatment, it is sent to the storage box 8.

[0061] The method for using the adaptive lotus root harvester of the present invention comprises the following steps:

[0062] Step 1: Preparation: Use the controller to start the travel motor 1-2, so that it drives the driving wheel 1-3 to rotate, and the driving wheel 1-3 is meshed with the tensioning wheel 1-5 and the driven wheel 1-4 and the crawler 1-6, so that the crawler 1-6 is wound, and the lotus root digger moves into the lotus field and walks to the working area. The driving motor starts the turbine screw lifting mechanism 6-1, so that the collection platform is located 5cm above the water surface, and the rear hydraulic pump 3-6 drives the hydraulic adjustment rod 3-2 to lower the multi-hole row nozzle 3-3 into the mud layer;

[0063] Step 2: Excavation work: Water pump a3-7 sucks water and sends it to the multi-hole row nozzle 3-3 to spray high-pressure water to disperse the mud layer. The walking device 1 continues to run, and the lotus root digger moves forward, so that the multi-hole row nozzle 3-3 is immersed in the deeper mud layer area, making it easy for the lotus root to float to the water surface.

[0064] Step 3: Harvesting and storage: The harvesting device drives the motor to work and transmit, and the lifting connecting rod 4-4 cooperates with the wedge-shaped pad 5-2 to make an elliptical motion, and the lotus roots are picked out and interlaced with the fixed spinning connecting rod 6-4, so as to collect the lotus roots and transfer them to the spinning connecting rod 6-4. The connecting rod 6-4 spins and transports the lotus roots to the conveyor belt 6-3, and after preliminary cleaning by the sprayer 7-2, they are transferred to the storage box 8.

[0065] Step 4: End of operation: After the collection is completed, the hydraulic pump 3-6 drives the hydraulic adjustment rod 3-2 to lift and retract the multi-hole row nozzle 3-3, and the lotus root digger moves out of the operation area and automatically goes ashore.
