Description

Technical Field

[0001] The utility model belongs to the technical field of lotus root harvesting equipment, and particularly relates to an obstacle-surmounting circular flushing type lotus root harvesting and fresh-keeping integrated machine structure. Background Art

[0002] Lotus root harvesting is one of the key links in the development of lotus root planting industry. At present, lotus root can be harvested by hand or by machine.

[0003] 1) Manual digging: Due to the harsh harvesting environment of lotus roots, especially in winter, lotus root farmers work in cold ice water, which is not only labor-intensive, but also inefficient, resulting in serious damage to the lotus roots and poor product quality;

[0004] 2) Mechanical digging. Currently, the mainstream mechanized lotus root digging equipment is mainly divided into floating and self-propelled types. The self-propelled type mainly adopts crawler-type walking and uses a high-flow hydraulic jet method. The sewage pump / clean water pump sends a high-pressure jet to the bottom of the lotus pond, flushing away the silt attached to the lotus roots. The lotus roots float to the surface with the help of buoyancy, and the lotus roots are harvested.

[0005] However, the existing flushing lotus root harvesting equipment usually adopts a rigid mobile chassis, which cannot effectively climb over obstacles with steep contact surfaces, and the use of external auxiliary equipment will greatly increase the working cost.

[0006] In addition, the lotus root harvesting equipment in the prior art usually does not have the function of preserving the lotus roots, and the harvested lotus roots require a lot of manpower and material resources for subsequent preservation. Utility Model Content

[0035] Furthermore, the flushing harvester group 1 includes a base 19, and the crawler walking mechanism 14 is installed on the left and right sides of the base 19; a digging mechanism 17 is provided below the base 19, and a support frame 18 is provided above it.

The drive motor 8 drives the rotating shaft 7 and the corresponding flushing nozzle to swing horizontally left and right through the synchronous belt 9.

[0036] Furthermore, the storage and preservation unit 2 includes a base 20, and the crawler walking mechanism 15 is installed on the left and right sides of the base 20; a lotus root storage box 13 is provided above the base 20, and a mud dripping mechanism 12 is provided on the top of the lotus root storage box 13, and a conveyor belt 11 is provided between the lotus root storage box 13 and the digging mechanism 17.

[0037] Furthermore, the water pump unit 3 includes a base three 21, and the crawler walking mechanism three 16 is installed on the left and right sides of the base three 21; a water pump and a water storage tank are provided above the base three 21, and the water pump is connected to the multiple flushing nozzles through a water supply pipe.

[0038] Furthermore, a gear motor mechanism 6 is provided between the support frame 18 and the base 19. The gear motor mechanism 6 includes a motor 1 fixed to the inner side of the support frame 18. The output end of the motor 1 is connected to a gear. The upper surface of the base 19 is provided with a rack meshing with the gear. The motor 1 drives the support frame 18 to move forward and backward relative to the base 19 to avoid obstacles through the coordination of the gear and rack.

[0039] Furthermore, the lower end of the conveyor belt 11 is adapted to the digging mechanism 17 , and the upper end of the conveyor belt 11 is opposite to the top entrance of the lotus root storage box 13 .

[0040] Furthermore, the mud dripping mechanism 12 includes a mud storage box and a plurality of spray holes, and the plurality of spray holes are evenly distributed directly above the lotus root storage box 13 .

[0042] Furthermore, a second motor is provided on the side of the conveyor belt 11, and the second motor is used to drive the conveyor belt 11 to move from bottom to top.

[0043] Furthermore, the plurality of flushing nozzles are installed at equal intervals in the horizontal direction below the front end of the support frame 18 .

[0044] Example 2. This embodiment provides a circular flushing lotus root harvesting and preservation integrated machine structure that can overcome obstacles, including a flexible crawler mobile chassis composed of three crawler sections. Each crawler chassis is equipped with a unit responsible for completing various functions, including a flushing harvesting unit, a storage and preservation unit, and a water pump unit. Each crawler section is connected by a shock absorber and a connecting plate, and the shock absorber can provide tension or pressure when overcoming obstacles.

[0045] Furthermore, each section of the crawler track is connected by a connecting plate, and the shock absorber is linked between the crawler track and the connecting plate by a pin. When the obstacle-surmounting circular flushing type lotus root harvester and fresh-keeping machine moves between adjacent lotus fields, it needs to cross the field. Because the uneven terrain causes a certain angle to be formed between each other's crawlers, the shock absorber will be subjected to tension or pressure, so that the adjacent crawlers will not form too large an angle with each other, thereby ensuring that the posture of the obstacle-surmounting circular flushing type lotus root harvester and fresh-keeping machine will not change too much and can smoothly overcome obstacles.

[0046] Furthermore, a gear motor mechanism, a rotating shaft mechanism, a drive motor, a synchronous belt and a flushing nozzle mechanism are provided on the crawler walking mechanism located in the front. When the lotus root harvesting operation is performed, the obstacle-surmounting circular flushing type lotus root harvesting and preservation integrated machine will use a high-pressure water gun to flush the lotus roots to the water surface, and then collect the lotus roots through the digging mechanism and transfer the lotus roots to the storage box. When the lotus root harvesting operation is performed, the flushing nozzle needs to be swung left and right to flush. When the flushing nozzle needs to be swung, the drive motor will continue to rotate, and the flushing nozzle rotating shaft will be driven to rotate through the synchronous belt, and then the flushing nozzle will be driven to swing left and right laterally, so as to achieve uniform flushing during operation;

[0047] When an obstacle appears in front, the gear motor mechanism drives the entire flushing device to retract backward through the rack mechanism to avoid touching the obstacle.

[0048] Furthermore, a dripping device and conveyor belt are installed on the second crawler track mechanism in the middle. This obstacle-surmounting circular flushing lotus root harvester and fresh-keeping machine uses mud coating to keep the lotus roots fresh. During operation, the conveyor belt collects the harvested lotus roots into a storage box, while the dripping device nozzle opens, evenly dripping the stored mud onto the lotus roots.

[0049] Furthermore, all parts of this application that are not described in detail are the same as the existing technology or are implemented using the existing technology.

[0050] In summary:

[0051] 1. The utility model provides a circular flushing lotus root harvesting and preservation integrated machine structure that can overcome obstacles. Through the flexible crawler mobile chassis composed of three-section crawler walking mechanism, connecting plates and shock absorbers, it can adapt to various terrains and realize the function of overcoming obstacles. At the same time, the flushing harvesting unit, storage and preservation unit, and water pump unit are integrated and installed on each section of the crawler walking mechanism, making it compact in structure and highly integrated, which can greatly improve the efficiency of lotus root harvesting and preservation and storage.

[0052] 2.
