Description

Potato picking mechanical arm

Technical Field

The utility model relates to a pickup attachment, in particular to arm is picked up to potato belongs to agricultural harvest machinery technical field.

Background

Potato is a worldwide economic crop and is called as underground apple and second bread. In the potato harvesting process, the potato blocks are subjected to the action of soil wrapping and buffering in the digging and lifting processes of the digging machine, so that the damage is less, and the existing digging machine can meet the requirements of the potato damage rate of the national industry standard. And because the potato piece loses soil protection in the potato pickup machine harvesting operation, the damage is great in the picking up process, the national industry standard is difficult to satisfy, and the machines and tools have the problems of overlarge size, unsuitability for small and medium-sized land operation and the like.

SUMMERY OF THE UTILITY MODEL

The utility model provides a potato pickup mechanical arm is a pickup mechanical arm suitable for the potato, can solve the current defect of picking up that the machine structure size is big, the potato rate is high of hindering effectively.

In order to solve the technical problem, the utility model provides a machinery arm is picked up to potato, including angle bar support, section bar frame, band pulley, driving motor, section bar pulley, terminal slide, terminal pushing mechanism, lead screw motor and belt, the belt is installed and is formed a closed loop on 8 band pulleys, realizes the motion in the whole arm horizontal plane through two peripheral band pulley direction of rotation of driving motor control, and the section bar pulley is equipped with to the motion contact segment.

As an optimal technical scheme of the utility model, lead screw motor and belt fixed connection.

As an optimal technical scheme of the utility model, the cooperation between lead screw and the terminal pushing mechanism, terminal slide has the guide effect.

As an optimal technical scheme of the utility model, the belt passes through and forms the closed loop with lead screw motor is fixed.

The utility model discloses the beneficial effect who reaches is: this arm is picked up to potato simple structure, it is lighter for current potato pickup machine, and the motion process is simpler. The accurate picking of the potatoes is realized, and the potato damage rate caused by picking the potatoes on a large scale is reduced.

Drawings

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention.

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. supporting by angle iron; 2. a profile frame; 3. a pulley; 4. a drive motor; 5. a profile pulley; 6. a terminal slide; 7. a terminal pushing mechanism; 8. a lead screw; 9. a lead screw motor; 10. a belt.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

As shown in figure 1, the utility model relates to a machinery arm is picked up to potato, including angle bar support, section bar frame, band pulley, driving motor, section bar pulley, terminal slide, terminal pushing mechanism, lead screw motor and belt, the belt is installed and is formed a closed loop on 8 band pulleys, realizes the motion in the whole arm horizontal plane through two peripheral band pulley direction of rotation of driving motor control, and the section bar pulley is equipped with to the motion contact segment.

Further, the screw motor 9 is fixedly connected with the belt 10, and the belt moves to drive the motor to move, so that the horizontal movement of the mechanical arm is realized.

Furthermore, the screw 8 and the tail end pushing mechanism 7 are matched with each other, so that the motion of the mechanical arm in the vertical direction is realized, and the tail end slide 6 has a guiding function on the mechanical arm, so that the limitation on the degree of freedom of the tail end pushing mechanism 7 in the horizontal direction is facilitated.

Furthermore, the belt 10 and the lead screw motor 9 are fixed to form a closed loop, so that the horizontal transmission of the mechanical arm is facilitated.

The utility model discloses a theory of operation: the driving motor 4 drives the belt wheel 3 to rotate, the belt wheel 3 is meshed with the belt 10, and the belt 10 is fixedly connected with the lead screw motor 9, so that the tail end execution arm is driven to move in the horizontal direction; the tail end executing arm is controlled to rotate forwards and backwards through the driving motor 4, the lead screw 8 is driven by the lead screw motor 9 above the potatoes, the tail end pushing mechanism moves up and down along the tail end slide way 6, and the potatoes are picked up.

The utility model relates to an arm is picked up to potato, simple structure picks up machinery for current potato and is lighter, and the motion process is simpler. The accurate picking of the potatoes is realized, and the potato damage rate caused by picking the potatoes on a large scale is reduced.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
