Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The utility model discloses a tread dolly sets up in the grain sieve separator, and the below of tread dolly is provided with screen tray or screen cloth. Because the area of sieve tray or screen cloth is great among the large-scale grain sieve separator, likepowder or granular crop distributes unevenly on sieve tray or screen cloth, just causes the jam easily to reduce the efficiency of sieving, the utility model discloses well tread dolly can scatter likepowder and granular crop evenly on the sieve tray uniformly, in order to prevent to block up.

As shown in fig. 1, the tread trolley comprises a trolley body 1, wherein the upper end of the trolley body is provided with a feeding pipe 2, the lower end of the trolley body is provided with an open discharge hole 3, and the feeding pipe, the trolley body and the discharge hole are communicated; grain crops enter the automobile body through the inlet pipe to discharge from the discharge gate through the automobile body, because the automobile body is removal, consequently grain crops can realize the large tracts of land and scatter along with the removal of automobile body.

A nut sleeve 4 and a slide bar sleeve 5 are fixed outside the vehicle body, the nut sleeve and the slide bar sleeve are symmetrically arranged on the left side and the right side of the vehicle body, a primary screw rod 6 is screwed in the nut sleeve, and a primary slide bar 7 is arranged in the slide bar sleeve; the first-level screw rod can provide motion power for the vehicle body, and the first-level slide bar can assist in stabilizing the vehicle body.

As shown in fig. 2, one end of the primary slide bar is fixedly connected to the x-axis electric cylinder support 8, and the other end is a free end; the x-axis electric cylinder bracket is positioned in the x-axis direction of the vehicle body; a motor 9 is arranged in the x-axis electric cylinder support, and an output shaft of the motor is connected with the first-stage screw rod in a transmission way.

The first-stage screw rod and the first-stage slide rod provide power and a track for the movement of the vehicle body, so that the vehicle body can move along the x axis. The first-level screw rod is provided with threads which are meshed with the nut sleeve, and when the first-level screw rod rotates under the action of the motor, the first-level screw rod is matched with the nut sleeve to change the rotation motion into linear motion, so that power support is provided for the motion of a vehicle body. And along with the different motion direction of lead screw, can realize the advancing and retreating of automobile body, move back and forth on the x axle of screen cloth and sow the crop.

A y-axis electric cylinder support 10 is arranged in the y-axis direction of the x-axis electric cylinder support, a secondary lead screw 11 and a secondary slide rod 12 which extend along the y-axis direction are arranged on the y-axis electric cylinder support, one end of the secondary lead screw is in transmission connection with a motor in the y-axis electric cylinder support, the other end of the secondary lead screw is a free end, and the secondary lead screw is in threaded connection with a nut sleeve fixed on the outer side of the x-axis electric cylinder support; one end of the secondary slide bar is fixed on the y-axis electric cylinder support, the other end of the secondary slide bar is a free end, and the free end penetrates through a slide bar sleeve fixed on the outer side of the x-axis electric cylinder support.

The second-stage screw rod and the second-stage slide rod both extend along the y axis, and a motor in the y-axis electric cylinder support acts on the second-stage screw rod to drive the second-stage screw rod to rotate, so that the nut sleeve meshed with the second-stage screw rod is driven to do linear motion. The electric cylinder support is the same as the vehicle body in motion principle, the secondary screw rod can provide power support for the x-axis electric cylinder support to move along the y axis, and the secondary slide bar can play a stabilizing role, so that the secondary screw rod and the secondary slide bar can drive the x-axis electric cylinder support to move along the y axis, and the vehicle body can move along the y axis. Therefore, under the combined action of the x-axis electric cylinder and the y-axis electric cylinder, the vehicle body can freely move on the x-axis and the y-axis.

For example: when the vehicle body is positioned at the root of the first-stage screw rod and the x-axis electric cylinder support is positioned at the root of the second-stage screw rod, the vehicle body can be considered to be positioned at an original point at the moment, namely the moving distances in the x-axis direction and the y-axis direction are both 0;

at the moment, a motor in the x-axis electric cylinder is started, so that the primary screw rod drives the vehicle body to move for 10 distances along the x axis, and the distance of crops which can be sowed by the vehicle body is 10 distances on the x axis;

when the vehicle body reaches the coordinate point of (0,10), starting the y-axis electric cylinder to enable the secondary lead screw to drive the x-axis electric cylinder bracket to move for 10 distances, gradually changing the position of the vehicle body from (0,10) to (10,10), and enabling the distance for the vehicle body to broadcast crops to be 10 distances on the y axis;

if the vehicle body repeatedly moves back and forth along the x axis for 10 distances in the process of moving for 10 distances along the y axis, the range of crops which can be sown by the vehicle body is a matrix of (0,0) - (10,10), that is, the range of crops which can be sown by the vehicle body can cover the whole surface of the screen or the sieve tray, and the technical aim of widely and uniformly sowing the crops is fulfilled.

As shown in fig. 2, the tread trolley is provided with a fixed bracket 13 for mounting the tread trolley around, and the fixed bracket is positioned above the sieve tray or the sieve mesh; the free end of the first-stage screw rod and the free end of the first-stage slide rod are inserted on the slide block 14 together, the slide block can slide along the y axis on the fixed support, and the first-stage screw rod is rotatably connected to the slide block through a bearing; the first-stage screw rod and the first-stage slide rod form a track for the movement of the vehicle body, and can assist the vehicle body to stably move. The slide block can move synchronously with the x-axis electric cylinder support, so that the y-axis movement of the vehicle body is not influenced while the fixing support fixes the first-level lead screw and the first-level slide bar.

The free end of the secondary screw rod is rotatably connected to the fixed bracket through a bearing; the free end of the second-stage sliding rod is fixedly connected to the fixed support. And the secondary screw rod and the secondary slide rod are used as tracks of the x-axis electric cylinder support to assist the x-axis electric cylinder support to move stably. Because y axle motor support, second grade lead screw and second grade slide bar all are fixed on the fixed bolster, need not remove along the x axle, consequently need not set up the slider at the free end of second grade lead screw and second grade slide bar.

A synchronous transmission crawler belt 15 is also arranged in the x-axis electric cylinder support; the motor is positioned above the primary screw rod, an output shaft of the motor is aligned with the end part of the primary screw rod, and the output shaft of the motor and the primary screw rod are synchronously transmitted through the synchronous transmission crawler; a synchronous transmission crawler belt is also arranged in the y-axis electric cylinder support; the motor is positioned above the secondary screw rod, an output shaft of the motor is aligned with the end part of the secondary screw rod, and the output shaft of the motor and the secondary screw rod are synchronously transmitted through the synchronous transmission crawler.
