Description

A kind of potato harvest facility

The utility model relates to agricultural machinery, particularly a kind of potato harvest device that is applicable to.

At present, the main harvesting approach of potato is by excavating, separate, collect bar, manually picking up.At the existing similar type that uses of China, generally by support and be fixed on the digger blade on the support, the garden dise knife that places the digger blade both sides, shake chain or vibratory sieve, transmission mechanism constitutes.When the conveying of potato piece and collection bar are when carrying the shake chain to finish by one, because the motion of shake chain is consistent with the machine traffic direction, and on the longitudinal axis that exists together, thereby its operation result is that the potato of results is laid on the road of next line operation of harvesting equipment, unit can roll the potato of having gathered in the crops when causing the next line results, influences the harvest operation of next line.When conveying, the branch discrete set bar of potato piece is when being finished by the lateral vibration sieve, the soil of excavating can not playback fully, causes the ground out-of-flatness, influences next step farmland operation.

The utility model purpose is according to above-mentioned the deficiencies in the prior art part, proposes a kind of potato harvester, and this device realizes that side direction collection bar and results back keep the ground opposed flattened after making potato harvest.

The utility model purpose realizes being realized by following technical scheme:

The utility model is by frame (8) and be fixed on digger blade (2) on the support, shake chain (5), the two garden dise knifes (1) and the transmission mechanism that are fixed on the support form, the garden dise knife is placed in the tool rest (9) of frame front end and is fixed on the frame by fastening bolt, it is characterized in that, also comprise the vibratory sieve (7) that is positioned at the frame rear portion, the position is connected with the shake chain, installation direction is vertical with the gantry motion direction, and vibratory sieve (7) hangs by crank (10) and rocking bar (11).

The utility model has the advantages that, in the results process, difference in functionalitys such as excavation, separation and results and side direction collection bar are effectively distributed to the corresponding work parts, and carried out reasonable disposition, thereby can fully realize its function, make the productivity ratio of harvesting equipment not be subjected to manually to pick up the influence of potato speed.Ground after the results is smooth, does not influence next step farmland operation.

Accompanying drawing 1 is the utility model front view;

Accompanying drawing 2 is accompanying drawing 1 vertical view;

Accompanying drawing 3 is an accompanying drawing 2A-A cutaway view;

The utility model feature and other feature are described in further detail by embodiment below in conjunction with accompanying drawing:

Show as accompanying drawing 1,2,3, the utility model is by frame (8) and be fixed on digger blade (2) on the support, shake chain (5), vibratory sieve (7), transmission mechanism, be fixed on two garden dise knifes (1) on the support, garden dise knife (1) is placed in the tool rest (9) of frame front end, be fixed on the frame (8) by fastening bolt, unclamp and to regulate it behind the bolt and move up and down and adjust the position; Digger blade (2) is positioned between the two garden dise knifes (1), connects with digger blade frame on the frame (8), wherein, a garden arcuation slotted hole is arranged on the digger blade, in order to adjust the operating angle of shovel, 20 °～30 ° of adjusting ranges; Shake chain (5) is the assembly that assembles, be that 30 chains of 30～40mm are formed and placed the digger blade rear end mainly by spacing, connect with frame with bolt, vibratory sieve (7) is placed on the rear portion of facility, hang by pivoted arm and rocking bar, can carry out sideshake, the position is connected with the shake chain, installation direction is vertical with the gantry motion direction, can realize potato piece side direction collection bar.

The utility model and 20～30 horsepowers of used with tractor trifilar suspension modes link, and can realize the lifting of facility and the adjustment of excavating depth.Power is by the tractor rear output shaft, reach through universal joint on the front axle (16) of these facility, belt pulley on front axle (15) reaches gear-box (14) again, tell two output shafts in the gear-box, 90 ° of its angles, axle (13) reaches the shake chain through the one-level belt pulley, between the preceding support wheel (3) of shake chain and the drive sprocket (6) eccentric wheel (4) is arranged, make the shake chain produce shake at the volley, strengthen the separating effect of earth and potato piece; Another gearbox output shaft (12) reaches rear axle through the one-level belt, drives crank (10) motion, and crank (10) drives rocking bar (11) again, and rotatablely moving of rear axle become the swing of vibratory sieve, makes potato piece side direction collection bar.

The utility model course of work: digger blade shovels out the mixture of potato piece and earth, advance forward simultaneously with facility, mixture is pushed backward, deliver on the shake chain, be delivered to vibratory sieve by the shake chain, in course of conveying, potato ball separates under the effect of conveying of shake chain leading after and shake with most of earth, and most of earth resets, add and put down the bar ditch that produces when excavating, the remaining earth of small part separates with the potato piece is very fast, and earth is fallen in the ditch substantially, and the potato piece then collects slivering in tractor one side, be convenient to manually pick up, thereby it is smooth to reach ground, results back, and the potato piece does not influence the next line harvest operation at a side collection bar.

Digger blade on the related frame of the utility model, shake chain, transmission mechanism, be fixed on the two garden dise knifes on the support and the structure and the relative dimensions of land wheel,, do not repeat them here by those skilled in the art of the same trade are known.

Claims (2)

1, a kind of potato harvest facility, by frame (8) and be fixed on digger blade (2) on the support, shake chain (5), be fixed on two garden dise knifes (1) on the support, transmission mechanism is formed, the garden dise knife is placed in the tool rest (9) of frame front end and is fixed on the frame by fastening bolt, it is characterized in that, also comprise the vibratory sieve (7) that is positioned at the frame rear portion, the position is connected with the shake chain, and installation direction is vertical with the gantry motion direction.

2, a kind of potato harvest facility according to claim 1 is characterized in that, vibratory sieve (7) hangs by crank (10) and rocking bar (11).
