Abstract

The invention relates to the field of agricultural machines, in particular to a water chestnut excavator, which consists of a hand tractor, a ploughing device, a transmission device, a rotary cutting and crushing device and a tail wheel device. The hand tractor is used for providing power; the ploughing device turns over soil on a sunned land to excavate water chestnuts growing under soil out; the rotary cutting and crushing device consists of a first rotary cutting shaft, a second rotary cutting shaft, harrow knives, a first support and a second support, and is connected with the ploughing device through the first supporting and connected with the tail wheel device through the second support; and the two adjacent harrow knives on the first rotary cutting shaft and the second rotary cutting shaft form a 120-degree included angle, and the harrow knives crush the soil turned over by the ploughing device constantly to expose the excavated water chestnuts from crushed oil. The water chestnut excavator can solve the problems of high labor intensity and low yield rate of the conventional artificial water chestnut harvest method, and the large-scale planting and high-efficiency harvest of the water chestnuts are realized.

Description

A kind of water chestnut digger

Technical field

The present invention relates to agricultural mechanical field, specifically a kind of water chestnut digger.

Background technology

The water chestnut mouthfeel is sweet crisp, and is nutritious, contains rich in protein, vitamin, carotin etc., and both edible can be used as medicinal material again, was popular seasonal product.Eleocharis perennial herb water plants, happiness are born in the pond or cultivate in the paddy field, and it mainly is grown in the mud in southern paddy field in China, and be cold winter the season of the water chestnut of gathering.At present, the gather method of water chestnut of people is manually to gather, cold weather, the implant mass that labour intensity is big, the factors such as efficient is low of gathering have restricted water chestnut.Therefore, the method for the existing water chestnut of manually gathering no longer satisfies people's production demand, presses for the high motorisation unit of a kind of efficient of gathering, promptly a kind of water chestnut digger.

Summary of the invention

Embodiment

The present invention is further detailed explanation below in conjunction with accompanying drawing.

As shown in Figure 1, a kind of water chestnut digger of the present invention, its device that plows is by first plough body 3, second plough body 6, the first plough body angle demodulator 5, the second plough body angle demodulator 7, the first plough body depth control device 17 and the second plough body depth control device 16 are formed, the first plough body angle demodulator 5 is in order to regulate the angle of first plough body 3, the second plough body angle demodulator 7 is in order to regulate the angle of second plough body 6, the first plough body depth control device 17 is in order to regulate the degree of depth that first plough body 3 plows, the second plough body depth control device 16 is in order to regulate the degree of depth that second plough body 6 plows, this device can open the soil behind roasting field, and the water chestnut that is grown under the soil is rolled up.

As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, transmission device is by power take-off 2, first chain-wheel mechanism, bevel gears, second chain-wheel mechanism, first driven shaft 29, second driven shaft 14 is formed, first chain-wheel mechanism comprises semicircle sprocket wheel 1, semicircle sprocket wheel 2 20, first sprocket wheel 15, chain 1, during use, semicircle sprocket wheel 1 and semicircle sprocket wheel 2 20 is connected by key with power take-off 2 earlier, then, connect by bolt 1 between semicircle sprocket wheel 1 and the semicircle sprocket wheel 2 20, and then symmetrical clamping is on power take-off 2, like this, be easy to loading and unloading, easy to operate; Bevel gears comprises large conical gear 21 and small conical gear 22, and this mechanism can be converted into the rotation of second driven shaft 14 around the x direction around the rotation of y direction with first driven shaft 29; Second chain-wheel mechanism comprises second sprocket wheel 24, the 3rd sprocket wheel 25, the 4th sprocket wheel 27 and chain 29, and this mechanism can give the rotary-cut breaker with transmission of power.

As Fig. 1, Fig. 3 and shown in Figure 4, the rotary-cut breaker is by the first rotary-cut axle 26, the second rotary-cut axle 28, rake cutter 10, first support 8, second support 11 is formed, wherein, the rotary-cut breaker links to each other with the device that plows by first support 8, link to each other with tail-pulley device by second support 11, become 120 ° of angles to arrange between the adjacent two rake cuttves 10 on the first rotary-cut axle 26 and the second rotary-cut axle 28, and can control the spacing of harrowing cutter 10 by the bolt of regulating on the rake cutter 10 2 23, also can suitably increase the quantity of rake cutter 10 according to the actual conditions of soil, the soil that the rotary-cut breaker can open the device that plows is constantly broken, and the water chestnut that rolls up is exposed from the soil of fragmentation.

As shown in Figure 1, tail-pulley device is made up of tail wheel mechanism 12, tail wheel mechanism height adjuster 13, regulate the height of tail wheel mechanism 12 by tail wheel mechanism height adjuster 13, and the rotary-cut breaker is connected by pin with tail-pulley device, has promptly regulated the height of rotary-cut breaker.

Adopt technique scheme, water with the field bleeds off earlier, roasting then field, when gathering water chestnut, device will plow earlier, transmission device, the rotary-cut breaker is connected with hand tractor successively with tail-pulley device, be assembled into a kind of water chestnut digger, drive it into field again, growing state according to water chestnut, by the first plough body angle demodulator first plough body is adjusted to suitable angle, by the second plough body angle demodulator second plough body is adjusted to suitable angle, by the first plough body depth control device first plough body is adjusted to suitable height, by the second plough body depth control device second plough body is adjusted to suitable height, by tail wheel mechanism height adjuster the rotary-cut breaker is transferred to suitable height again.During work, to open through the soil behind the roasting field by the device that plows earlier, the water chestnut that is grown under the soil is rolled up, then, constantly broken by the rotary-cut breaker soil that device opens that will plow again, make to roll up the water chestnut that comes and from the soil of fragmentation, expose, the water chestnut that the staff will expose is picked up and gets final product, if the distribution density of water chestnut is bigger, the spacing that operating personnel can dwindle the rake cutter by the bolt of regulating on the rake cutter two increases rake cutter quantity and gets final product.
