Description

Technical Field

[0001] The utility model belongs to the field of agricultural mechanical equipment, in particular to a water chestnut harvester. Background Art

[0002] Water chestnut, also known as Marti and water chestnut, is rich in starch and can be eaten raw, cooked, or used as medicine. It tastes sweet and can stimulate the appetite, detoxify, eliminate food stagnation, and strengthen the stomach. It is a common cooking ingredient and fruit south of the Qinling Mountains in China, and is also one of the main canned exports of China.

[0003] Water chestnuts are paddy field crops. The planting process is similar to rice planting. After the paddy field is filled with water, a rotary tiller is used to break up the soil about 10 cm thick on the surface of the paddy field and plant the seedlings. Water chestnuts grow in the alternating position of the soft mud layer and the hard mud layer of the paddy field, and the fruit drop depth is about 9-20 cm.

[0004] The existing Chinese patent CN106416576A discloses a water chestnut harvester, including a frame, a power device is installed above the front end of the frame, and a digging shovel device is installed below the front end of the frame, including a shovel blade, which is hingedly installed at the front end of the frame, and motors are installed on the left and right sides of the shovel blade to drive the shovel blade to change its angle; a separation device is installed in the middle of the frame, which is driven by a main shaft and a chain, and a plurality of rollers are installed on the chain. The main shaft is connected to the power device through a pulley device, and a flexible jacket is installed on the outer surface of the rollers. The spacing between the rollers can be adjusted according to the diameter of the water chestnut; a spraying device is arranged above the separation device in the middle of the frame, a crossbeam is installed at the upper end of the frame, a water inlet pipe is installed on the crossbeam, and a plurality of spray heads are connected below the water inlet pipe; walking wheels are installed below the frame, and a slide plate and a collecting device are installed at the rear end of the frame.

[0005] Although the above device improves the harvesting efficiency of water chestnuts, it is unable to break up the clay adhered to the surface of water chestnuts, resulting in a large amount of soil mixed in the collection box, occupying the collection space, accelerating the replacement frequency of the collection box, and affecting work efficiency. Therefore, it is improved. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0028] Example 1

[0029] refer to Figure 1-3 As shown, the utility model provides a water chestnut harvester, comprising: a frame 1, a mud discharge mechanism is arranged at the front end of the frame 1, a deep soil shoveling mechanism is arranged on the frame 1 at the rear end of the mud discharge mechanism, a conveying mechanism 16 is arranged on the frame 1 at the rear end of the deep soil shoveling mechanism, a clay crushing mechanism is arranged on the frame 1 above the front end of the conveying mechanism 16, a flushing mechanism is arranged on the frame 1 above the middle end of the conveying mechanism 16, a collecting box 2 is arranged on the frame 1 below the rear end of the conveying mechanism 16, and a walking mechanism is arranged at the bottom end of the frame 1.

[0030] As a preferred embodiment, the mud discharge mechanism comprises: a mounting frame 3, a plurality of first height adjustment holes 4 are provided on both sides of the mounting frame 3, the mounting frame 3 is bolted to the front end of the frame 1 through the first height adjustment holes 4, a blade cover 5 is fixed to the bottom end of the mounting frame 3, a spiral blade 6 is rotatably arranged in the blade cover 5, a certain gap is provided between the spiral blade 6 and the blade cover 5, the blade shaft of the spiral blade 6 is connected to the first motor 7 through a belt, and a first slide groove 8 is also provided on the side wall of the mounting frame 3, a lockable first diagonal support rod 9 is slidably arranged in the first slide groove 8, and the other end of the first diagonal support rod 9 is hinged to the frame 1. In this embodiment, the number of the first height adjustment holes 4 is three. Considering that the depth of water chestnuts in different fields may vary, the discharge depth of the mud discharge mechanism is set to three gears, and the discharge depth of the shallow soft mud is adjusted by adjusting the relative position of the mounting frame 3 and the first height adjustment hole 4. Driven by the first motor 7, the spiral blade 6 rotates to separate the shallow soft mud, including rice straw, stubble and other debris.

[0031] As a preferred embodiment, the frame 1 is provided with a plurality of second height adjustment holes 10, and the deep soil shoveling mechanism comprises: a rake body 11, the rear end of the rake body 11 is fixed to the second height adjustment hole 10 by bolts, the front end of the rake body 11 is rotatably provided with a tooth rake 12, the two side ends of the rake body 11 are symmetrically provided with a plurality of limit holes 13, the two side ends of the tooth rake 12 are symmetrically provided with angle adjustment holes 14 corresponding to the limit holes 13, the limit holes 13 are bolted with second diagonal braces 15, and the other end of the second diagonal braces 15 is bolted to the corresponding angle adjustment hole 14. When working, the tooth rake 12 needs to shovel into the deep soil to harvest water chestnuts, and the forward resistance it encounters will be greater than that of the rake body 11. Therefore, a tooth gap is provided between the tooth rakes 12, and the width of the tooth gap is made smaller than the minimum thickness of the water chestnut, so that the soil passes through the tooth gap position, thereby reducing the resistance encountered by the tooth rake 12. Although water chestnuts are mainly concentrated in the soil layer of 9 to 20 cm deep, the soil depth of water chestnuts in each field is different. In actual use, the shoveling angle and the soil penetration depth of the tooth rake 12 are adjusted through the angle adjustment hole 14 and the second height adjustment hole 10 according to the conditions of different fields.

[0032] As a preferred embodiment, the transmission mechanism 16 includes: a chain conveyor belt, a roller is arranged between the chain conveyor belts, the chain conveyor belt is a double-row chain, the roller is connected between the double-row chains, and under the rotation of the sprocket, the double-row chain will drive the roller to move forward together, and a second motor 17 is arranged in the frame 1, and the sprocket of the chain conveyor belt is transmission-connected to the second motor 17. It should be noted here that the roller on the chain conveyor belt has a certain gap, and the gap is smaller than the minimum thickness of the water chestnut, so that the mixed soil can leak out from the gap.

[0033] As a preferred embodiment, the clay crushing mechanism includes: a roller 18, on which a number of arc-shaped protrusions 19 are evenly distributed, and the roller shaft of the roller 18 is connected to the third motor 20 through a belt. There is a certain gap between the clay crushing mechanism and the transmission mechanism below, and the size of the gap is determined according to the size of the water chestnut, so only larger clay blocks will be broken, and the water chestnuts will be safely transported from the bottom of the clay crushing mechanism. Considering that water chestnuts will stick together in larger clay blocks, if the rotation speed of the roller 18 is too fast, the water chestnuts therein will be damaged. Therefore, the roller 18 should be kept rotating at a low speed, and the hardness of the clay is lower than that of the water chestnut, so a lower rotation speed can crush the clay wrapped outside the water chestnut. Furthermore, the arc-shaped protrusions 19 on the roller 18 are not sharp, which can minimize the damage to the water chestnut.

[0034] As a preferred embodiment, the flushing mechanism includes: a support base 21, the support base 21 is fixed on the frame 1, a water tank 22 is fixed on the support base 21, and a high-pressure nozzle is arranged at the bottom of the water tank 22. Because the clay is very sticky, after the clay is crushed, there will still be clay attached to the water chestnuts, so it needs to be flushed again to further remove the clay.

[0035] As a preferred embodiment, a shaft 23 is fixed on the frame 1 above the rear end of the conveying mechanism 16, and a soft brush 24 is provided at the lower end of the shaft 23. The soft brush 24 can further scrub the water chestnuts conveyed, thereby obtaining relatively pure fruits.

[0036] As a preferred embodiment, the walking mechanism includes: walking wheels 25, and the walking wheels 25 are driven by a driving motor. A handle 26 is fixed to the rear end of the frame 1. The harvesting worker can control the walking direction of the machine through the handle 26 and move forward steadily under the drive of the driving motor.

[0037] As a preferred embodiment, a battery is arranged in the frame 1, and the battery is used to supply power to the first motor 7, the second motor 17, the third motor 20 and the driving motor.
