Description
Technical Field
The invention relates to the technical field of harvesting machinery, in particular to a digging shovel for potato crops.
Background
The potato is positioned as the fourth major food crop in China since 2015, but the mechanization level of the potato is far from enough compared with the food crops such as wheat and corn. Digging is the most important link in potato harvesting, and a digging shovel is an important part on a potato harvester. The digging shovel is used for digging out potato pieces and soil together and transferring the potato pieces and the soil to the separating component. The digging shovel is required to dig the potato blocks completely under the condition of digging soil as little as possible, the digging depth is stable, the soil breaking capacity is high, and the phenomena of grass winding and soil accumulation during working are avoided.
Present potato digger blade's simple structure, kind are more single, and the structure of adopting the integral type more with the harvester can not change alone when the digger blade front end takes place to warp or appear the breach, and does not have the special digger blade that is suitable for different soil conditions in different areas such as northeast or northwest, and the suitability is poor.
Disclosure of Invention
The invention aims to solve the problems in the prior art and researches and designs a novel digging shovel of a potato harvester. The device can adjust the excavation depth as required, and has stronger soil crushing capability to the soil with serious adhesion.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows: the device mainly comprises a left shovel, a middle small shovel and a right shovel which are connected, wherein the left shovel and the right shovel are of bilateral symmetry design structures, two screw holes in the outer sides of the left shovel and the right shovel and the screw hole in the upper portion of the middle are respectively connected with a rack bolt, and the middle small shovel is fixed between the left shovel and the right shovel through a bolt. The left shovel and the right shovel are trapezoidal in soil-entering part, so that the shovel is suitable for excavating operation in a sand and stone environment, the soil-entering resistance is reduced, and the deformation caused by collision of the front end with stones in soil is reduced; the inclined blades are arranged at the soil-entering parts of the left shovel and the right shovel, the inclined surfaces of the inclined blades and the main shovel plane form a 30-degree angle, the angle ensures that the shovel blade has good soil-entering performance, reduces the traction resistance of operation, reduces energy consumption, and ensures that the blade tip of the inclined blade cannot be too sharp to easily deform or collide with stones to form a notch, so that the service life of the shovel blade is prolonged. The head of the middle small shovel arranged between the left main shovel and the right main shovel is designed to be triangular, and the structure has the functions of reducing the width of the main shovel and enhancing the grass sliding capacity of the shovel blade. The included angle between the shovel point and the horizontal ground is 18-25 degrees when the digging shovel works, in order to ensure that the trench bottom dug by the shovel blade of the harvester is flat when the shovel blade works, the vertex angle clamped by two side lines of the head part of the middle small shovel is designed to be 140 degrees.
The invention has novel, simple and reasonable structure, easy manufacture, small operation traction resistance, high connection stability and strong adaptability.

Description of part numbers in the figures:
a left shovel 1; a screw 2; a right shovel 3; a fixing screw hole 4; a middle small shovel 5;
the specific implementation mode is as follows:
the invention is described in further detail below with reference to the following figures and detailed description:
as shown in figures 1, 2, 3 and 4, the digging shovel structure principle schematic diagram of the novel potato harvester is provided, and the digging shovel structure schematic diagram mainly comprises a left shovel 1, a screw 2, a right shovel 3, a fixed screw hole 4 and a middle small shovel 5.
The working principle of the invention is explained below, when in work, two screw holes on the outer sides of the left shovel (1) and the right shovel (3) are respectively connected with a harvester frame bolt, two ends of a screw of the middle small shovel (5) are respectively fixed between the left main shovel (1) and the right main shovel (3) through two bolts, five positioning holes are respectively arranged on the left side and the right side of the middle small shovel (5), and the distance and the included angle between the left shovel (1) and the right shovel (3) and the action height of the middle small shovel (5) can be realized by changing the connecting positions of the left main shovel (1) and the right main shovel (3) and the middle small shovel fixing screw hole (4). The buried parts of the left shovel (1) and the right shovel (3) are designed to be trapezoidal, so that the structure is more suitable for excavation operation in a sand and stone environment, the resistance of the digging shovel blade during burying is effectively reduced, and the deformation caused by collision between the front end of the digging shovel blade and stones in soil during digging operation is reduced; the digging parts of the left shovel (1) and the right shovel (3) are all provided with the inclined blades, the inclined blade inclined planes and the main shovel plane form 30 degrees, the angle ensures the good digging performance of the shovel blade, reduces the traction resistance of the operation, plays a role in reducing energy consumption, ensures that the tip of the inclined blade can not be too sharp, prevents the digging shovel from deforming or colliding with stones due to the resistance when the operation advances, and prolongs the service life of the digging shovel. The head of a middle small shovel (5) arranged between the left main shovel (1) and the right main shovel (3) is designed to be triangular, and the structure has the functions of reducing the width of the main shovel and enhancing the grass sliding capacity of the shovel blade. Because the included angle between the shovel point and the horizontal ground is in the range of 18-25 degrees during the digging shovel operation, in order to ensure that the trench bottom dug during the shovel blade operation of the harvester is flat, the vertex angle clamped by the two side lines of the head part of the middle small shovel is designed to be 140 degrees.
The invention has novel, simple and reasonable structure, easy manufacture and small operation traction resistance, and greatly improves the operation environment adaptability of the machine tool.
The double-row double-shovel excavator can adjust the distance and the angle between the left main shovel and the right main shovel according to different land operation conditions, can perform double-row operation, and has the characteristics of simple structure, reasonable layout, convenience in adjustment, and high universality and stability.
The invention is suitable for digging operation of various potatoes.
