Description

Technical Field

[0001] This utility model relates to the field of material transportation technology, and in particular to a material transportation device for greenhouse facilities. Background Technology

[0002] Greenhouses, or facility agriculture greenhouses, are frame-and-film structures with excellent heat insulation properties, enabling people to enjoy out-of-season vegetables. However, the exits of greenhouses are generally located on their sides, and the greenhouses are typically quite long, resulting in a considerable amount of labor involved in transporting materials in and out of the greenhouse. Therefore, people have begun to explore building rail-guided transport vehicles inside vegetable greenhouses to assist in transporting goods.

[0003] Currently, rail transport vehicles generally use circular single tracks, which cannot enter between rows (between different planting areas) to transport materials, leaving a considerable distance for manual handling.

[0004] Chinese patent (authorization announcement number CN 217262695 U, authorization announcement date 2022.08.23) discloses an automatic transportation system for greenhouses, specifically including a track mechanism, a conveying mechanism, and a control mechanism; the track mechanism is fixed to the upper part of the inner wall of the greenhouse and surrounds the entire internal space of the greenhouse. It is evident that this technical solution enables the transportation of materials within the greenhouse; however, its track is a circular monorail encircling the interior of the greenhouse, making it unsuitable for transporting materials between rows.

[0005] Therefore, how to provide a material transportation device for greenhouse facilities that can increase the transportation operation area, can flexibly and conveniently enter the ridges for transportation operations, and has the characteristics of simple structure and low manufacturing cost is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the present invention proposes a material transport device for greenhouse facilities, aiming to solve the above-mentioned technical problems. The material transport device for greenhouse facilities proposed in this invention can increase the transport operation area, can flexibly and conveniently enter the rows for transport operations, and has the advantages of simple structure and low manufacturing cost.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] This utility model provides a material transportation device for greenhouse facilities, comprising:

[0009] The track includes a first track and a second track; the second track includes parallel tracks that are horizontally opposite to and spaced apart from the first track and a reversing track that is offset away from the first track; the parallel tracks and the reversing track are smoothly connected.

[0010] A traveling mechanism includes a traveling frame, a first traveling mechanism, a second traveling mechanism, a first lifting mechanism, and a second lifting mechanism. The traveling frame is located between a first track and a parallel track. The first traveling mechanism rolls against the first track, and the second traveling mechanism rolls against the parallel track. The fixed ends of both the first and second lifting mechanisms are fixed to the upper part of the traveling frame. The lifting end of the first lifting mechanism is fixed to the first traveling mechanism and drives it to rise and fall to disengage from or abut against the first track. The lifting end of the second lifting mechanism is fixed to the second traveling mechanism and drives it to rise and fall to disengage from or abut against the parallel track.

[0011] The cargo-carrying part is fixed to the lower end of the walking frame;

[0012] The controller is electrically connected to the first walking mechanism, the second walking mechanism, the first lifting mechanism, and the second lifting mechanism.

[0013] As can be seen from the above technical solution, compared with the prior art, the material transportation device for greenhouses disclosed in this utility model is designed with a double-track structure. The first traveling mechanism travels on the first track, and the second traveling mechanism travels on a parallel track of the second track. The first lifting mechanism can lift the first traveling mechanism to make it rise and fall away from or abut against the first track, and the second lifting mechanism can lift the second traveling mechanism to make it rise and fall away from or abut against the parallel track. When it is necessary to travel along the first track, the second traveling mechanism is lifted by controlling the second lifting mechanism to make the second traveling mechanism fall away from the parallel track, and the first traveling mechanism and the traveling frame drive the load part to travel along the first track. The first track can be arranged along the length of the greenhouse to realize the material transportation along the length of the greenhouse. When it needs to travel along the second track, the second traveling mechanism abuts against the parallel track for support. The first traveling mechanism is lifted by controlling the first lifting mechanism, causing it to detach from the first track. The second traveling mechanism, through the traveling frame, drives the load-bearing unit along the second track. The reversing track of the second track can be arranged along the width of the greenhouse, i.e., along the inter-row passage between adjacent planting areas, to achieve material transport along the width of the greenhouse. By controlling the flexible switching of the first and second traveling mechanisms on the parallel track section, the direction of travel of the transport device is controlled, thus enabling material transport along the length and width of the greenhouse. This utility model proposes a material transport device for greenhouses that can increase the transport operation area, allowing for flexible and convenient entry into the inter-row transport operations, achieving the technical effects of simple structure and low manufacturing cost.

[0014] As a further improvement to the above technical solution, both the first track and the second track are arranged in the upper part of the facility greenhouse;

[0015] The traveling frame includes a vertical rod and a crossbeam. The vertical rod is perpendicular to the first track and the parallel track and passes through the two. The crossbeam is vertically fixed to the upper end of the vertical rod above the first track and the second track. The fixed ends of the first lifting mechanism and the second lifting mechanism are fixed to the two ends of the crossbeam respectively. The load-bearing part is fixed to the bottom end of the vertical rod.

[0016] The beneficial effects of the above technical solution are: both the first and second tracks are arranged in the upper part of the greenhouse to form a suspended track, which does not occupy the ground space of the greenhouse and will not affect the planting work of the growers; the load-bearing part is fixedly connected to the upper crossbeam frame through the vertical hanging rod to form a suspended transport structure.

[0017] As a further improvement to the above technical solution, the first walking mechanism includes a support frame, a walking wheel, and a drive motor; the top of the support frame is fixed to the lifting end of the first lifting mechanism; the walking wheel is mounted on the bottom of the support frame via axle A and rolls against the top of the first track; the drive motor is fixed on the support frame and its driving end is connected to the axle A.

[0018] The second walking mechanism includes a second support frame, a second walking wheel, and a second drive motor; the top of the second support frame is fixed to the lifting end of the second lifting mechanism; the second walking wheel is mounted on the bottom of the second support frame via axle B and rolls against the top of the parallel track; the second drive motor is fixed on the second support frame, and its driving end is connected to the axle B.

[0019] Both drive motor one and drive motor two are electrically connected to the controller.

[0020] The beneficial effects of the above technical solution are: drive motor one is connected to drive wheel one, and drive motor two is connected to drive wheel two; independent drive control of drive wheel one and drive wheel two can be realized.

[0021] As a further improvement to the above technical solution, the distance from the bottom end of the vertical boom to the bottom end of the traveling wheel is more than 1m.

[0022] The beneficial effects of the above technical solution are: a suspension length of more than 1m can ensure the stability of the device's own movement when switching tracks.

[0023] As a further improvement to the above technical solution, the first support frame and the second support frame are inverted U-shaped frames, and the wheel axle A is rotatably connected to the opposite side walls of the first support frame; the wheel axle B is rotatably connected to the opposite side walls of the second support frame.

[0024] As a further improvement to the above technical solution, the carrying part can be any one of a transport pallet, transport frame, carrying frame, or carrying box.

[0025] As a further improvement to the above technical solution, the horizontal distance between the first track and the parallel track is 10cm to 25cm.

[0026] The beneficial effect of the above technical solution is that the small gap of 10cm to 25cm between the first track and the parallel track can ensure that the device does not shake significantly when switching tracks.

[0027] As a further improvement to the above technical solution, the first lifting mechanism and the second lifting mechanism are electric push rods or servo electric cylinders.

[0028] As a further improvement to the above technical solution, a charging power supply is also included, which is fixed to the bottom of the carrying part; the charging power supply is electrically connected to the controller.

[0029] The beneficial effects of the above technical solution are: placing a charging power source with a certain mass at the bottom of the carrying part can improve the stability of the device's movement and reduce shaking.

[0030] As a further improvement to the above technical solution, there are multiple second tracks, which are arranged at intervals along the length of the first track.

[0031] The beneficial effects of the above technical solution are: the first track can be arranged along the length of the greenhouse, and the reversing tracks of multiple second tracks can be arranged along the ridges, thus forming a transport channel covering multiple planting areas of the greenhouse, which can reduce the amount of manual handling and improve the efficiency of material transportation.

[0032] As can be seen from the above technical solution, compared with the prior art, the present utility model discloses a material transportation device for greenhouse facilities, which has the following advantages and beneficial effects:

[0033] 1. This utility model constructs a first walking mechanism and a second walking mechanism that can be controlled independently on the first track and the second track, which can realize flexible track changing and facilitate track arrangement in the longitudinal and lateral channels of the greenhouse, thereby increasing the transportation operation area.

By controlling the first traveling mechanism 22 and the second traveling mechanism 23 to flexibly switch tracks in the parallel track 121 section, the direction of travel of the transportation device is controlled, thereby realizing material transportation along the length and width of the greenhouse. The material transportation device for greenhouses proposed in this utility model can increase the transportation operation area, and can flexibly and conveniently enter the inter-row for transportation operations, achieving the technical effects of simple structure and low manufacturing cost.
