Description

Technical Field

[0001] The utility model relates to a towed agricultural bulk particulate matter transport vehicle, belonging to the technical field of agricultural machinery, and specifically relates to a particulate matter transport and storage vehicle for agricultural use. Background Art

[0002] Bulk grain transport vehicles, bulk seed transport vehicles, bulk feed transport vehicles, etc. can all be classified into the category of agricultural bulk particulate matter transport vehicles. The agricultural bulk particulate matter transport vehicle is a type of agricultural vehicle, which includes a class of motor vehicles for transporting bulk particulate goods on rural roads and a short-distance low-speed bulk particulate matter towed transport vehicle for use in fields or sites.

[0003] The Chinese patent publication number CN212074121U discloses a utility model patent with the name of a seed transport vehicle convenient for dumping. Referring to paragraph

[0005] of the specification, it includes a carrier plate. The left side of the top of the carrier plate is fixedly connected with a support hinge, and the top of the support hinge is fixedly connected with a hopper. The right side of the top of the carrier plate is fixedly connected with a housing. The bottom of the right inner wall of the housing is fixedly connected with a first bearing and a second bearing. The outside of the housing is fixedly connected with a turntable. The inside of the second bearing is fixedly connected with a rotating shaft, and the front end of the rotating shaft is fixedly connected with a disc. The bottom of the front of the disc is movably connected with a connecting plate, and the top of the back of the connecting plate is movably connected with a lifting plate. By using the cooperation of the carrier plate, the housing, the hopper, the first bearing, the second bearing, the turntable, the rotating shaft, and the disc, the existing seed transport vehicle that is not convenient for users to dump seeds is solved. From the description of this technical solution in the patent specification, it can be seen that the use function of this transport vehicle is also limited to the point-to-point transport of bulk particulate matter in agricultural production, and it does not have the auxiliary storage function of providing bulk particulate matter supply for other agricultural machinery during travel.

[0004] Referring to paragraph

[0018] of the specification, the working principle is as follows: The operator opens the discharge pipe and rotates the turntable through the handle. The turntable drives the worm and the worm gear to rotate. The worm gear drives the rotating shaft to rotate. The rotating shaft drives the disc to rotate. The rotation of the disc drives the lifting plate to rise through the connecting plate. The rising of the lifting plate drives the frame to rise through the vertical plate and at the same time drives the rotating plate and the hopper to tilt to the left with the support hinge as the center. After the hopper tilts, the seeds are discharged into the interior of the hopper through the discharge pipe, achieving the purpose of convenient dumping. From the description of this technical solution in the patent specification, it can be seen that when dumping seeds, this transport vehicle uses a manual mechanical structure to lift one end of the hopper upward. The upward lifting force of the manual lifting mechanical structure is limited, which in turn affects the load-bearing capacity of the hopper of the transport vehicle and the transport capacity of the transport vehicle.

[0048] As Figure 1 shown, a towed agricultural bulk particulate transporter of the present utility model includes a box body 1, a chassis frame 2, and front and rear load-bearing wheels 3. The box body 1 is fixedly arranged on the chassis frame 2, the chassis frame 2 is arranged on the front and rear load-bearing wheels 3, an opening 1a for facilitating the loading of crop particles is provided on the box body 1, a rotary shed cover 4 for covering the box body 1 is provided at the opening 1a, a screw discharge device 5 for unloading crop particles is arranged outside the box body 1, and the screw discharge device 5 is connected to the box body 1 through a material flow hopper 6.

[0049] Specifically Figure 2 shown, the bottom of the box body 1 is provided with a trapezoidal box bottom 1b, a material flow port 1c is provided on one side of the box bottom bin 1b, a flow control device 7 is provided on the outer side wall of the box bottom bin 1b where the material flow port 1c is located, and the rear end of the material flow hopper 6 is connected to the front end of the material flow port 1c.

The receiving hopper 5f and the discharging hopper 5g are respectively arranged at the bottom and top of the material conveying cylinder 5a, the spiral blade 5e is spirally arranged on the rotating rod 5d and both are arranged inside the cylinder body of the material conveying cylinder 5a. The screw discharge device 5 is detachably connected to the front end of the material flow hopper 6 through the receiving hopper 5f provided on the material conveying cylinder 5a. The motor 5b is connected to the speed reducer 5c, one end of the rotating rod 5d outside the material conveying cylinder 5a is connected to the speed reducer 5c, and the motor 5b drives the speed reducer 5c to rotate and the speed reducer 5c drives the rotating rod 5d and the spiral blade 5e to rotate inside the material conveying cylinder 5a. Refer to Figure 1As shown, the middle part of the feeding cylinder 5a of the screw discharging device 5 is connected to the box body 1 through a connecting rod device 8.

[0051] A traction type agricultural bulk particulate matter transport vehicle of the present utility model is used for short-distance transfer of crop particles from a warehouse to a sowing machine cabin or the box body of a large long-distance transport vehicle. Refer to Figure 1 and Figure 2 As shown, the crop particles are loaded into the box body 1 of the transport vehicle by a loading device. After the transport vehicle is towed by other vehicles to a designated position of the sowing machine or the long-distance transport vehicle. The discharge hopper 5g on the feeding cylinder 5a of the screw discharging device 5 is arranged above the sowing machine cabin or the box body of the large long-distance transport vehicle. The motor 5b is powered on to drive the rotating rod 5d and the spiral blade 5e to rotate in the feeding cylinder 5a.
