Description

Technical Field

[0001] The invention belongs to the technical field of agricultural greenhouses, and in particular relates to an agricultural planting greenhouse. Background Art

[0002] Currently, vegetable planting seasons are very limited. To extend the growing season, expand vegetable cultivation, and provide off-season produce for sale, plastic greenhouses have become essential for vegetable production, and are therefore widely used in rural areas. With the improvement of living standards in both urban and rural areas, greenhouses for growing fresh vegetables and fruits in winter are booming and growing in scale. A greenhouse is composed of a framework made of bamboo or wood poles, concrete poles, or lightweight steel or pipes. These are then covered with plastic film to create an arched, circular structure that insulates the interior.

[0003] Most greenhouses have an arched top design. When designing and using them, it is necessary to combine the actual meteorological information of the place of use and the installation materials of the greenhouse. The curvature of the greenhouse is fixed. In order to facilitate lighting and wind protection, the arch length of the greenhouse in some places is longer and the height is lower, which makes the angle between the two sides of the greenhouse arch very small. Therefore, when the planting area in the greenhouse needs to be turned over and loosened, mechanized equipment can easily scratch the bottom of the greenhouse, affecting the service life of the greenhouse and the quality of crop planting in the greenhouse.

[0004] Based on this, an agricultural planting greenhouse with a lifting and adjusting unit is proposed. Summary of the Invention

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0027] like Figure 1-3 As shown, the present invention provides a technical solution: an agricultural planting greenhouse, comprising a greenhouse arch frame 1, side frames 2 are respectively fixed at the two connecting ports of the greenhouse arch frame 1, the greenhouse arch frame 1 and the two side frames 2 constitute the main structure of the greenhouse, and reinforcing beams are fixed on both sides of the greenhouse arch frame 1 close to the planting ground, and a plurality of connecting columns 3 are vertically fixed at equal intervals on the ground of the reinforcing beams, and the bottom end of each of the connecting columns 3 is respectively connected to a lifting adjustment unit 4; the parts of the connecting columns 3 and the lifting adjustment unit 4 that are higher than the planting ground are covered with a shed cloth when in use, and are used in conjunction with the main structure of the greenhouse.

[0028] The lifting and adjusting unit 4 consists of a first connecting seat 5, a second connecting seat 6 and a third connecting seat 7. A first pin seat 53 is fixed to the outer side of the first connecting seat 5, a second pin seat 64 is fixed to the outer side of the second connecting seat 6, and a third pin seat 74 is fixed to the outer side of the third connecting seat 7. Threaded pins are respectively threaded on the first pin seat 53, the second pin seat 64 and the third pin seat 74. The first connecting seat 5, the second connecting seat 6 and the third connecting seat 7 are fixedly connected by a pin plate 8.

[0029] In order to facilitate stable connection between the first connecting seat 5 , the second connecting seat 6 and the third connecting seat 7 , the length of the pin plate 8 is greater than the longitudinal length between the first pin seat 53 and the third pin seat 74 .

[0030] The top of the first connecting seat 5 is provided with a connecting cavity 51, and the connecting column 3 is clamped in the connecting cavity 51. The bottom of the first connecting seat 5 is rotatably connected to a first roller 52, and the first roller 52 is slidably connected to the second connecting seat 6;

[0031] A first support plate 61 is fixed to a side end of the second connecting seat 6 . A first slideway 62 is provided on the first support plate 61 . The first roller 52 is slidably connected to the first slideway 62 .

[0032] In order to avoid slipping, the first slide 62 is an inwardly concave closed slide, and an anti-derailment plate is provided at the tail end of the first slide 62. The length of the first slide 62 is not greater than the length of the first support plate 61.

[0033] The other end of the first support plate 61 is rotatably connected to the second roller 63, and the side end of the third connecting seat 7 is fixed with a second support plate 71. The second roller 63 is slidably connected to the second support plate 71. Specifically, the second support plate 71 is provided with a second slide 73, and the second roller 63 is slidably connected in the second slide 73.

[0034] The second support plate 71 is fixed with a protective plate 72 at the tail end of the second slide 73. The top end of the protective plate 72 is against the tail end of the first support plate 61. The protective plate 72 can prevent planting soil from entering the second slide 73, which is beneficial to the normal use of the second roller 63.

[0035] The length of the first support plate 61 is set to 100-130 mm, and the length of the second support plate 71 is not less than the length of the first support plate 61 .

[0036] The bottom end of the third connecting seat 7 is pre-buried in the planting ground.

[0037] A lifting support plate 65 is fixed to the side of the second connecting seat 6 facing away from the first support plate 61. The lifting support plate 65 is used to connect with the lifting power mechanism. The lifting power mechanism is an external hydraulic cylinder. When in use, the telescopic shaft of the hydraulic cylinder is rotated and connected to the lifting support plate 65. The first connecting seat 5, the second connecting seat 6 and the third connecting seat 7 of the lifting adjustment unit 4 cooperate with each other to complete the unilateral height lifting and adjustment operation of the greenhouse main structure.

[0038] Specifically, when it is necessary to loosen the soil of the planting site close to the greenhouse arch frame 1 of the greenhouse main structure with a low height and a small angle between the two sides of the greenhouse arch, first open the pin plate 8 connecting part between the second connecting seat 6 and the third connecting seat 7 on the side where the soil needs to be loosened, and at the same time continue to connect the pin plate 8 connecting part between the first connecting seat 5 and the second connecting seat 6 so that the first connecting seat 5 and the second connecting seat 6 can be stably connected, and then connect the same number of hydraulic cylinders as the second connecting seats 6 to the lifting support plate 65 outside each second connecting seat 6 on this side, and then adjust the structure of the lifting adjustment unit 4 on the opposite side;

[0039] Specifically, the pin-plate 8 connection portion between the first connecting seat 5 and the second connecting seat 6 is opened, and the pin-plate 8 connection portion between the second connecting seat 6 and the third connecting seat 7 is continued to be connected, so that the second connecting seat 6 and the third connecting seat 7 can be stably connected;

[0040] Then the hydraulic cylinder is turned on, so that the hydraulic cylinder drives the second connecting seat 6 to rise through the lifting support plate on this side. When the second connecting seat 6 is raised, the second roller 63 slides in the second slide 73, so that the inclination angle of the first support plate 61 increases. At the same time, the first roller 52 of the first connecting seat 5 of the lifting adjustment unit 4 on the opposite side slides freely on the first slide 62. When the hydraulic cylinder drives the first support plate 61 to rise and fall to the appropriate position, the height of the hydraulic cylinder is locked so that the hydraulic cylinder remains fixed to the ground, and the operation of raising the main structure of the greenhouse on one side is completed. Then, a tiller or a rotary tiller is used to turn over and loosen the soil on this side. When turning over the soil, the area between each two lifting adjustment units 4 is used as a single operation area to avoid damage to the third connecting seat 7. After the operation is completed, the hydraulic cylinder is used to reset the main structure of the greenhouse. Similarly, the turning over and loosening of the planting soil near the greenhouse arch frame 1 of the main structure of the greenhouse on the other side is completed, which is efficient and convenient.
