Crawler-type harvester for cyperus esculentus

Abstract

The invention relates to a crawler-type harvester for cyperus esculentus. According to the technical scheme, a soil crushing and feeding device driven by an engine, a lifting and conveying device, anupper layer vibrating screen, an auger-type soil throwing and crushing device, a lower layer vibrating screen, a horizontal conveying vibrating screen and a material receiving and lifting mechanism are arranged on a frame; a feeding end of the soil crushing and feeding device is connected with a feeding end of the lifting and conveying device; a discharge end of the lifting and conveying device isconnected with a feeding end of the upper layer vibrating screen; a discharge end of the lower layer vibrating screen is connected with a feeding end of the horizontal conveying vibrating screen; a discharge end of the horizontal conveying vibrating screen is connected with a feeding hole of the material receiving and lifting mechanism; a discharge hole of the material receiving and lifting mechanism is connected with a feeding hole of the upper part of a harvesting box; and a travelling mechanism is a travelling crawler arranged at two sides of a chassis. The crawler-type harvester has a wide application range, integrates multiple functions of excavating and soil crushing, root crushing, separating, screening and recycling, is suitable for high-efficiency harvesting of the cyperus esculentus, is easy to move, and has a great popularization prospect.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a crawler-type bean harvester. Background technique [0002] In the past, manual excavation was generally required when digging oily bean, which was labor-intensive and inefficient. There are some rhizome excavators on the market now, which greatly improves the efficiency of excavation and reduces labor intensity, such as the "oil sand bean combine harvester" with the application number "201320772694.1" that the inventor applied for earlier, but due to its structural The problem is that the scope of application is small, it can only be used for one kind of root crops, and the yield is low, often making the fruit leak from the gap, the screening effect is not ideal, causing serious economic losses, and because it is traction, when When the fruit is harvested to a certain weight, the front is light and the rear is heavy, and the front is tilted. Therefore, 1 mu of land needs to unload the...

[0002] In the past, manual excavation was generally required when digging oily beans, which was labor-intensive and inefficient

There are some rhizome excavators on the market now, which greatly improves the efficiency of excavation and reduces labor intensity, such as the "oil sand bean combine harvester" of "201320772694.1" that the inventor applied for earlier, but due to its structural The problem is that the scope of application is small, it can only be used for one kind of root crops, and the yield is low, often making the fruit leak from the gap, the screening effect is not ideal, causing serious economic losses, and because it is traction, when When the fruit is harvested to a certain weight, the front is light and the rear is heavy, and the front is tilted. Therefore, it is necessary to unload the fruit 3-4 times per mu of land, the work efficiency is low, and the use effect is not satisfactory.

The application number is "201620865285.X" for "a self-propelled shallow rhizome combine harvester", but in the process of use, it is difficult to adapt to small grain crops, the yield is low, the screening effect is not ideal, and the separation is not clean. The use effect is unsatisfactory, causing serious economic losses. Although the "self-propelled small particle root crop combine harvester" applied by the applicant with the application number "201710786754.8" has extended the screening length, due to the large number of screens and the The position is high, causing the machine to vibrate greatly, and it cannot be used at all in practice. Fast harvesting, improving the screening effect and yield of small-grain root crop fruits have become a fantasy, and it is impossible to apply it in practice. The applicant's previous application number is "A self-propelled small particle root crop harvester" of "2018205160320" has solved the above problems to the greatest extent, but in the actual application process, there are still the following problems: 1. The unit harvesting area is small, and the maximum unit harvesting area needs to be increased. The direct way is to increase the harvesting width of the harvester, but after the width increases, its weight will increase, and it also needs matching power. Because of its walking mechanism, the road wheel has weak grip and limited power, and the form of the road wheel is difficult. Satisfied; this limits the overall width and weight of the machine, resulting in a small unit harvesting area; 2. Due to the existence of the material receiving lifting mechanism, the overall height is high. If the overall height exceeds 4.8m when transported by truck, the lowest level of road height limit It is also 4.5m, and the height limit of most highways is 4.2m, which makes it impossible to transfer; 3. The vibration mode of the upper double-layer vibrating screen and the lower double-layer vibrating screen is: the vibrating arm drives the upper double-layer vibrating screen to vibrate, and then passes through the upper part. The vibration of the double-layer vibrating screen drives the vibration of the lower double-layer vibrating screen. The force of the lower layer needs to pass through the body of the upper double-layer vibrating screen and then be transmitted downward, resulting in a large force on the upper double-layer vibrating screen, high vibration force, and high energy consumption. It is easy to be damaged and has a short service life; 4. During the screening process, larger and harder soil clods are difficult to break, especially in the northern cold and frozen soil areas and areas with hard soil clods, it is difficult to obtain a net yield of Shadou. ensure
