Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery transportation, in particular to a track changer for a greenhouse transport vehicle. Background Art

[0002] When harvesting in agricultural greenhouses, transport vehicles are generally used for transportation. In order to improve the convenience of transportation, remote control is generally used to move the transport vehicles placed on the transport track. However, sometimes it is necessary to change tracks for transportation. For this reason, the track is generally changed at the intersection of the tracks through a track changer so that the transport vehicle can be smoothly transferred from one track to another. Most of the existing greenhouse transport vehicle track changers need to be disassembled and replaced for track change. However, this method not only consumes a lot of materials, but also requires that the extra track change part be placed on one side for standby, which is more laborious and time-consuming to operate. For this reason, a greenhouse transport vehicle track changer is designed that is convenient for quick track change, convenient for greenhouse transport vehicles to change tracks smoothly, and has a simple structure and low consumables.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example:

[0027] Specifically, two straight line stations 3 are provided on the substrate 1, and the line connecting the two straight line stations 3 is parallel to the track changing slide 2 and is located on a side away from the fixed point of the track changing link and the substrate 1. When the side of the track changing link provided on the track changing slide 2 is aligned with the straight line station 3, the track changing link remains straight, and a plurality of track changing stations 4 are provided at intervals on the sides of the two straight line stations 3. When the side of the track changing link provided on the track changing slide 2 is aligned with the track changing station 4, the track changing link forms an arc state. By setting the straight line station 3 and the track changing station 4, it is convenient to maintain parallel movement of the track when the track changing link is aligned with the straight line station 3, and to change the track when the track changing link is aligned with the track changing station 4.

[0028] Specifically, the positioning mechanism includes a positioning pin 10 which is slidably set on the base plate 1 and perpendicular to the side of the track changing slide 2. A plurality of positioning rings 9 adapted to the positioning pin 10 are fixedly installed on the track changing slide 2 at intervals. The spacing arrangement of the plurality of positioning rings 9 is consistent with the spacing arrangement of the linear station 3 and the plurality of track changing stations 4. When the track changing chain link is aligned with any one of the linear station 3 or the track changing station 4, any one of the plurality of positioning rings 9 can be aligned with the positioning pin 10, and then the positioning pin 10 can be inserted thereinto, so that the track changing slide 2 can be locked in position to prevent the track changing slide 2 from moving laterally when the greenhouse transport vehicle changes tracks.

[0029] Specifically, a handle 12 is fixedly mounted on the positioning pin 10 and is arranged perpendicular to the positioning pin 10. The base plate 1 also includes a stopper 13 adapted to the handle 12. Guide rings 11 are provided on both sides of the handle 12 and are slidingly matched with the positioning pin 10. The two guide rings 11 are fixedly connected to the base plate 1. The setting of the handle 12 makes it convenient to push and pull the positioning pin 10. The setting of the stopper 13 makes it convenient to avoid the positioning pin 10 from retreating when the positioning pin 10 is inserted into any one of the positioning rings 9, thereby further improving the positioning and fixing stability of the positioning mechanism. The setting of the two guide rings 11 makes it convenient to guide the positioning pin 10, and under the action of the handle 12, the positioning pin 10 is locked on the base plate 1 to prevent the positioning pin 10 from detaching from the base plate 1.

[0030] Specifically, it also includes an adjustment mechanism for adjusting the position movement of the track-changing slide 2. The adjustment mechanism includes an adjustment rod 6 that is rotatably connected to the base plate 1 through a positioning shaft 5 in the middle. A guide shaft 7 is fixedly installed on the track-changing slide 2. An adjustment groove is provided at one end of the adjustment rod 6 for guiding and sliding with the guide shaft 7. It is convenient to rotate the adjustment rod 6 and cooperate with the guide shaft 7 and the adjustment groove to drive the track-changing slide 2 to slide on the base plate 1.

[0031] Specifically, a track change mark 8 is provided on the base plate 1 at a position on the other side of the adjustment rod 6, and the track change mark 8 is used to conveniently indicate the track change direction.

[0032] Specifically, the top and bottom of the track-changing slide bar 2 are both provided with limit bars 14 that slide with the track-changing slide bar 2, and the limit bars 14 are fixedly connected to the base plate 1. Through the setting of the limit bars 14, it is convenient to limit the track-changing slide bar 2 and prevent the track-changing slide bar 2 from detaching from the base plate 1.
