Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a greenhouse curtain rolling machine. Background Art

[0002] Nowadays, agricultural development uses greenhouses to allow crops to grow in winter. In winter, greenhouses usually need to be covered with straw curtains or thermal blankets on the shed cloth at night to prevent crops from freezing to death in the cold night. At present, straw curtains and thermal blankets are usually laid by people standing on the roof of the shed, and then manually releasing the rolled straw curtains and thermal blankets, so that the rolled straw curtains and thermal blankets are laid on the surface of the shed under the action of gravity. When rolling up the straw curtains and thermal blankets, people also stand on the roof of the shed, and then manually pull the rope at the bottom of the straw curtains or thermal blankets, so that the straw curtains and thermal blankets are rolled up and pulled to the roof. Among them, since straw curtains or thermal blankets are generally narrow, in the actual laying process, they need to be pulled from the bottom of the greenhouse to the top one by one, which is not only time-consuming and labor-intensive, but also delays the growth of crops.

[0003] In response to the above problems, the utility model patent with the authorization publication number CN207099900U discloses a greenhouse curtain rolling machine, the key points of which are that it includes a curtain rolling shaft, a reducer, a motor, an electrical control box, a rocker arm, a sleeve rod and a support rod. The curtain rolling shaft is fixed to the output end of the reducer, one end of the rocker arm is fixed to the reducer, and the other end is hinged to one end of the sleeve rod. The axis of the hinged shaft is parallel to the axis of the curtain rolling shaft. The other end of the sleeve rod is sleeved on the support rod that matches the hole of the sleeve rod. The hole inside the sleeve rod is a square hole. The bottom of the support rod is fixed to the ground. The motor is fixed on the rocker arm to drive the reducer, and the electrical controller controls the forward and reverse rotation of the motor. The utility model uses a curtain rolling machine to roll up a greenhouse straw curtain at a time, which solves the problem of wasting time in the curtain rolling process and increases the irradiation time of crops.

[0004] Although the above-mentioned automated structure for rolling up straw curtains and thermal insulation blankets overcomes the defects of existing manual covering, in actual use, one such roller can only roll up the straw curtains or thermal insulation blankets on one side of the greenhouse, while another roller needs to roll up the straw curtains or thermal insulation blankets on the other side of the greenhouse simultaneously. Therefore, the cost and energy consumption of rolling up the straw curtains or thermal insulation blankets of the entire greenhouse are generally high. At the same time, the straw curtains or thermal insulation blankets rolled up by the roller shaft will eventually be rolled up to the top of the greenhouse by the roller shaft, so that the weight of the roller shaft and the rolled-up straw curtains and thermal insulation blankets are all concentrated on the roof, which is not only easy to bend the top of the shed frame, but also once the shed frame is loose, the weight is very likely to cause the shed frame to collapse, fall apart, and other risks. Utility Model Content

[0007] The utility model is further configured as follows: rectangular boxes with openings facing the greenhouse body are fixedly arranged on both sides of the greenhouse body, and the first and second winding rollers are rotatably installed inside the two rectangular boxes.

[0008] The utility model is further configured as follows: the rotating assembly includes a pair of worm gears respectively fixedly mounted on the first unwinding roller and the second unwinding roller, a transmission shaft with two ends respectively rotatably connected to the ends of two rectangular box bodies, a pair of worms fixedly mounted on the transmission shaft and respectively meshing with the two worm gears, and a motor fixedly mounted on the ends of a rectangular box body and with the output end fixedly connected to the transmission shaft.

[0009] The utility model is further configured as follows: a protective cover is fixedly provided at the end of the rectangular box body to surround and protect the safety of the worm gear and the worm transmission, the two ends of the transmission shaft rotate and pass through the side walls of the two protective covers respectively, the motor is fixedly installed on the side wall of a protective cover, and the output end of the motor rotates into the protective cover to connect with the transmission shaft.

[0010] The utility model is further configured as follows: one end of the protection cover away from the rectangular box body is screwedly connected with a cover plate.

[0011] The utility model is further configured as follows: the transmission shaft includes shaft body one and shaft body two, and coupling one connecting one end of shaft body one and shaft body two, the two worm gears are fixedly mounted on shaft body one and shaft body two respectively, the output end of the motor and the other end of shaft body one are connected via coupling two, coupling one is located between two protective covers, and coupling two is located inside one protective cover.

[0012] The utility model is further configured as follows: the arched bracket comprises a pair of arched frames which are parallel to each other and have a certain gap therebetween, and a plurality of connecting rods whose two ends are respectively fixedly connected to one side of the two arched frames, and the rotating wheel is rotatably sleeved on the connecting rods.

[0013] The utility model is further configured as follows: an annular groove is provided on the contour surface of the rotating wheel, and the traction rope is stuck in the annular groove.

[0014] The utility model is further configured as follows: rectangular support seats connecting both ends of all arch supports are fixedly arranged on both sides of the greenhouse body, a plurality of connecting frames are commonly connected between adjacent arch supports, and the connecting frames and the rectangular support seats are parallel to each other.

[0015] The utility model is further configured as follows: the second winding roller is located on both sides of the traction rope and is respectively fixedly provided with a limiting disc.

[0016] The beneficial effect of the utility model is that by adopting the above technical scheme, when it is necessary to lay a thermal insulation curtain above the greenhouse body, the motor will first drive the transmission shaft to rotate in the positive direction, so that the transmission shaft drives the two worms in the two protective covers to respectively engage and transmit the two worm wheels, and then the two worm wheels will drive the winding rollers 1 and 2 in the two rectangular boxes to rotate synchronously. Since the two rectangular boxes are located on both sides of the greenhouse body and the traction rope is placed on the rotating wheel of the arch bracket, the winding rollers 1 and 2 will respectively unwind the thermal insulation curtain during their rotation. The thermal insulation curtain and the winding traction rope are wound up, and the thermal insulation curtain is unfolded and pulled onto the arch bracket at the same time. Because the arch bracket is located above the greenhouse body, the thermal insulation curtain pulled onto the arch bracket will also cover and insulate the upper part of the greenhouse body, thereby realizing the automatic laying of the thermal insulation curtain of the greenhouse body; conversely, when the thermal insulation curtain on the greenhouse body needs to be rolled up, it is only necessary to drive the drive shaft to rotate in the opposite direction by the motor, so that the unwinding roller one rolls up the thermal insulation curtain and the unwinding roller two unwinds the traction rope, thereby achieving the effect of automatically rolling up the thermal insulation curtain above the greenhouse body.

[0017] The above-mentioned roller shutter machine only uses one motor as energy source to realize automatic laying and automatic winding of thermal insulation curtains. Compared with the two traditional roller shutter machines working separately, it has low cost and energy consumption. At the same time, in the process of winding and unwinding the thermal insulation curtain, not only will most of the weight of the thermal insulation curtain not be concentrated on top of the greenhouse, but the arched bracket will also share part of the weight of the greenhouse, thereby fully ensuring the safety and stability of the greenhouse structure.

[0025] like Figure 2As shown, rectangular boxes 10 with openings facing the greenhouse body 1 are fixedly arranged on both sides of the greenhouse body 1, and the unwinding roller 1 4 and the unwinding roller 2 5 are rotatably installed inside the two rectangular boxes 10. By adopting the above-mentioned rectangular boxes 10, the unwinding roller 1 4, the unwinding roller 2 5, the thermal insulation curtain 2 and the traction rope 7 can be shielded to a certain extent to prevent the staff from being pinched or strangled. Among them, the unwinding roller 2 5 is located on both sides of the traction rope 7 and is fixedly provided with limiting discs 51, which can limit the unwinding activities of the traction rope 7 on the unwinding roller 2 5 to a certain extent, so as to ensure that the unwinding roller 2 5 can stably wind the traction rope 7.

[0026] like Figure 3 As shown, the rotating assembly 6 includes a pair of worm gears 61 respectively fixedly mounted on the unwinding roller 1 4 and the unwinding roller 2 5, a transmission shaft 62 whose two ends are rotatably connected to the ends of the two rectangular box bodies 10, a pair of worms 63 fixedly mounted on the transmission shaft 62 and respectively meshing with the two worm gears 61, and a motor 64 fixedly mounted on the ends of a rectangular box body 10 and whose output end is fixedly connected to the transmission shaft 62; the transmission shaft 62 includes a shaft body 1 621 and a shaft body 2 622, and a coupling 1 623 connecting one end of the shaft body 1 621 and the shaft body 2 622, the two worm gears 63 are respectively fixedly mounted on the shaft body 1 621 and the shaft body 2 622, the output end of the motor 64 and the other end of the shaft body 1 621 are connected via a coupling 2 624, the coupling 1 623 is located between the two protective covers 101, and the coupling 2 624 is located inside a protective cover 101. By adopting the above-mentioned transmission shaft 62 structure, it is convenient for workers to quickly disassemble and assemble the roller shutter machine for transportation and transfer.

[0027] like Figure 2 , Figure 3 As shown, a protective cover 101 is fixedly provided at the end of the rectangular box body 10 to surround and protect the transmission safety of the worm wheel 61 and the worm 63. The two ends of the transmission shaft 62 rotate through the side walls of the two protective covers 101 respectively. The motor 64 is fixedly installed on the side wall of one protective cover 101, and the output end of the motor 64 rotates into the protective cover 101 to connect the transmission shaft 62. By adopting the above-mentioned protective cover 101, the meshing safety of the worm wheel 61 and the worm 63 can be effectively ensured, and the staff can be prevented from accidentally touching and getting injured. Among them, the end of the protective cover 101 away from the rectangular box body 10 is screwed with a cover plate 102, which can facilitate the staff to maintain and maintain the internal parts of the protective cover 101.

[0028] like Figure 1 , Figure 2As shown, the arch support 8 includes a pair of arch frames 81 parallel to each other with a certain gap between them, a plurality of connecting rods 82 with two ends fixedly connected to one side of the two arch frames 81, a rotating wheel 9 is rotatably sleeved on the connecting rod 82, an annular groove 91 is provided on the contour surface of the rotating wheel 9, and the traction rope 7 is stuck in the annular groove 91. By adopting the connection structure of the arch support 8 and the rotating wheel 9, not only can the thermal insulation curtain 2 and the traction rope 7 be stably supported, but also the annular groove 91 of the rotating wheel 9 can effectively limit the traction rope 7 from moving at the same position of all rotating wheels 9, thereby ensuring that the traction rope 7 safely and stably pulls the thermal insulation curtain 2 to unfold above the greenhouse body 1. Among them, rectangular support seats 11 connecting the two ends of all arch supports 8 are fixedly provided on both sides of the greenhouse body 1, and a plurality of connecting frames 12 are commonly connected between adjacent arch supports 8, and the connecting frames 12 and the rectangular support seats 11 are parallel to each other, which can further improve the structural stability of the arch support 8 to ensure the safe and stable operation of the rolling curtain machine.

[0029] The working principle of this embodiment:

[0030] When it is necessary to lay the thermal insulation curtain 2 on the greenhouse body 1, the motor 64 will first drive the transmission shaft 62 to rotate in the positive direction, so that the transmission shaft 62 drives the two worms 63 in the two protective covers 101 to respectively engage and drive the two worm gears 61, and then the two worm gears 61 will drive the winding roller 1 4 and the winding roller 2 5 in the two rectangular boxes 10 to rotate synchronously. Since the two rectangular boxes 10 are located on both sides of the greenhouse body 1 and the traction rope 7 is placed on the rotating wheel 9 of the arch bracket 8, the thermal insulation curtain 2 will be unwound and the traction rope will be wound up during the rotation of the winding roller 1 4 and the winding roller 2 5. 7, and at the same time, the thermal insulation curtain 2 is unfolded and pulled onto the arch bracket 8. Because the arch bracket 8 is located above the greenhouse body 1, the thermal insulation curtain 2 pulled onto the arch bracket 8 will also cover and insulate the top of the greenhouse body 1, thereby realizing the automatic laying of the thermal insulation curtain 2 of the greenhouse body 1; conversely, when it is necessary to roll up the thermal insulation curtain 2 on the greenhouse body 1, it is only necessary for the motor 64 to drive the transmission shaft 62 to rotate in the opposite direction, so that the winding roller 1 4 rolls up the thermal insulation curtain 2 and the winding roller 2 5 unwinds the traction rope 7, thereby achieving the effect of automatically rolling up the thermal insulation curtain 2 above the greenhouse body 1. The above-mentioned roller shutter machine uses only one motor 64 as energy source to realize automatic laying and automatic winding of the thermal insulation curtain 2. Compared with the two traditional roller shutter machines working separately, the cost is low and the energy consumption is low. At the same time, in the process of winding and unwinding the thermal insulation curtain 2, not only will most of the weight of the thermal insulation curtain 2 not be concentrated above the greenhouse, but the arched bracket 8 will also share part of the weight of the greenhouse, thereby fully ensuring the safety and stability of the greenhouse structure.
