Adjustable potato digging and conveying shovel

Abstract

The invention discloses an adjustable potato digging and conveying shovel which comprises a digging and conveying piece, an adjusting mechanism and a device support. The digging and conveying piece ismainly composed of a digging piece, a conveying piece, a pre-tightening spring, a vertical adjusting rod, a fixed sleeve and a digging piece installing pin shaft, wherein the pre-tightening spring and the vertical adjusting rod are connected with the digging piece and the conveying piece. The adjusting mechanism is mainly composed of a vertical shaft, a left stand column, a right stand column, acompression spring, an adjusting transverse rod, a servo motor and a cam and boss matched pair matched with the servo motor. The device support is mainly composed of a three-point hanging flange, a flange base, an upper support and a lower support. The digging and conveying mechanism is connected with the adjusting mechanism. The adjusting mechanism is connected with the device support. By means of the shovel, the problem is solved that a conventional digging shovel is consistent in digging depth and difficult to adjust on the two sides, so potato fruits on a slope are left and injured; meanwhile, by means of the shovel, the dug broken soil and potato fruits are further separated conveniently later through the conveying piece; the shovel is simple in structure and particularly suitable forharvesting potatoes in terrains with irregular planting soil gradients in China.

Description

technical field [0001] The invention relates to an adjustable potato excavating and conveying shovel, which belongs to the field of agricultural machinery and is especially suitable for potato planting land with uneven and irregular slopes. Background technique [0002] Agricultural land is the cornerstone of the healthy growth of crops and the basic material and object of labor for human survival. my country is a large agricultural country, with arable land area of ​​about 2.024 billion mu, accounting for about 20.9% of the total land area. Land resources are abundant, and land resources can be divided into plateaus, mountains, hills, plains, and basins according to terrain. The distribution of various land resources varies. Among them, the area of ​​mountains and hills accounts for about 43% of the total area, mainly distributed in the southwest, southeast and northwest regions of China. Due to the extremely uneven distribution of water resources in our country and the gre...

Problems solved by technology

However, these three provinces are located in the southwestern region, and potatoes are mostly planted in mountainous or hilly areas. The land in these areas has a certain slope different from the land in the plain area. During the potato planting process, it can only be planted along the slope surface, so for different Location Potato crop plants have different root distribution in the soil. When the slope is relatively low, the overall distribution of potato roots is also relatively low. As the slope rises, the overall distribution of potato roots also increases. Between the hilly areas, the slope of the soil varies greatly. The distribution of potato roots is due to the slope, so the distribution of potato fruits is also different. Because the existing vehicle-mounted potato digging mechanisms are all flat land or the range of slope changes is small. In the case of large and irregular potato hilly planting, it is easy to cause a high rate of fruit damage during the harvest process, affecting production efficiency, which provides a certain degree of difficulty for the mechanized planting and large-scale operation of potatoes in the southwest

[0004] At present, related patents related to potato harvesting and digging mechanisms include: Potato Harvester Adjustable Frame (2012104923882). The main function of this device is to adjust the width and depth of potato harvesting, which cannot be satisfied with mountains and hills with a certain slope. Strip potato harvesting; a digging shovel (2015105956209) for harvesting potatoes. To reduce the traction resistance and power consumption during harvesting, the adjustment of the shovel face and blade of the digging shovel is the adjustment of the whole digging shovel, and it cannot meet the use of slope potato harvesting; the vibration type potato digging mechanism (2017107404654), the device is in The limit beams are supported on the two limit seats, the central shafts are respectively installed on the two support seats, and the eccentric wheel is used to complete the vibration. The application range of the device is wide, but the applicability to slope potato digging is not very high

The above-mentioned patents are adjusted by adjusting the angle of the excavating shovel and the cutting edge, or by adjusting the width and angle of the frame, which can meet the requirements of different working conditions to a certain extent, but this adjustment cannot fully meet the irregularities of mountains and hills.
