Description

Novel potato harvester digger blade

Technical Field

The utility model belongs to the technical field of the harvest machinery technique and specifically relates to a potato class crop digger blade is related to.

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.

The digger blade of the existing potato harvester is simple in structure and single in type, and is integrated with the harvester, the front end of the digger blade cannot be independently changed when being deformed or a notch appears, the digger blade is not suitable for a special digger blade in different soil conditions in different regions such as northeast or northwest, and the applicability is poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a novel potato harvester digger blade for the problem that exists to above-mentioned prior art has been researched and designed. 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 above purpose, the utility model adopts the following technical scheme: 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; all there is the sloping blade at left and right shovel position of penetrating into the soil, and this structure sloping blade inclined plane is 30 with main shovel plane, and this angle has both guaranteed the good performance of penetrating into the soil of spiller, has reduced the drag resistance of operation and has reduced the energy consumption, guarantees again that the sloping blade knife tip is unlikely to cross the point and produces easily and warp or with the stone collision breach appears, increases this utility model's life. 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 utility model discloses novel structure, simple reasonable, manufacturing are easy, and the operation drag resistance is little, and connection stability is high, 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 fig. 1, 2, 3 and 4, the utility model provides a novel digging shovel structure principle schematic diagram of potato harvester, the utility model 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 utility model is explained below, during operation, two screws in the left shovel (1) and the right shovel (3) outside are connected with harvester front end frame bolted connection respectively, and middle spade screw (5) both ends are fixed respectively by two ties between left and right main shovel (1) (3), and there are five transposition holes in the middle spade (5) left and right sides respectively, and the accessible changes the hookup location of left and right main shovel (1) (3) and middle spade fixed screw (4) and realizes the effect height of distance, contained angle and middle spade between the left and right shovel. 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 main shovel (1) and the right main shovel (3) are 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 18-25 degrees when the shovel is used for digging, in order to ensure that the bottom of a ditch dug by the shovel blade of the harvester is flat when the shovel blade is used for digging, the vertex angle clamped by two side lines of the head part of the middle small shovel (5) is designed to be 140 degrees.

The utility model discloses novel structure, simple reasonable, make easily, the operation drag resistance is little, very big improvement machines operation environmental suitability.

The utility model discloses can be according to different soil operation conditions, distance and angle between the main shovel about the adjustment, but the double-row operation has simple structure, rationally distributed, adjust convenient, commonality and the high characteristics of stability.

The utility model is suitable for a multiple potato class excavation operation.
