Description

Technical Field

[0001] The utility model belongs to the technical field of fertilization in greenhouses, and particularly relates to a water and fertilizer spraying device in a greenhouse. Background Art

[0002] Currently, there are two main types of pipe arrangements for transporting water (and water-fertilizer mixtures) within greenhouses: overhead and buried. The buried arrangement involves installing multiple vertical risers above the buried pipes, with sprinklers mounted on top to complete the spraying operation. However, this riser arrangement presents several challenges in practical applications.

[0003] Firstly, because the risers extend vertically upward within the greenhouse, they inevitably occupy a certain amount of space. During daily agricultural production activities, when personnel operate or use mechanical equipment within the greenhouse, they can easily come into contact with or even squeeze the risers. These external forces can easily cause the risers to tilt. Once tilted, the connection between the riser and the buried pipe is affected, making it susceptible to loosening. Over time and with continued external forces, the connection can become further damaged, leading to leakage of the water and fertilizer solution. This not only impacts normal spraying and fertilization operations but can also pollute the environment in which crops grow.

[0004] Furthermore, when the riser is tilted by force, its connection to the buried pipeline generates a pulling force, causing the buried pipeline to tilt toward the surface. This disrupts the normal arrangement of the buried pipeline, potentially causing deformation and rupture, seriously impacting the subsequent stable operation of the buried pipeline. This not only requires significant manpower and material resources for repair, but can also delay fertilization and irrigation, adversely affecting crop growth. Utility Model Content

[0005] The utility model provides a water and fertilizer spraying device in a greenhouse, which has the characteristics of reducing the interference effect of agricultural activities on water and fertilizer transportation pipelines.

[0006] The utility model provides following technical scheme: including buried water and fertilizer delivery pipe, connecting pipe head, stand and water and fertilizer shower head, be provided with connecting cover between connecting pipe head and stand, the connecting cover is connected in connecting pipe head top end through flange, be equipped with intercommunication groove, limiting groove and limiting top mouth in connecting cover, intercommunication groove with connecting pipe head internal space intercommunication, the limiting groove inner wall is rotatably connected with ball type cover, ball type cover is installed in stand bottom, ball type cover is equipped with two openings, ball type cover two openings are respectively with stand and intercommunication groove alignment, stand side wall with limiting top mouth inner wall contact, stand passes through ball type cover with intercommunication groove internal space intercommunication, connecting cover outside installation has outer support cover, a plurality of reset springs are arranged between outer support cover and stand, a plurality of reset springs are distributed in the periphery of the stand in a circular array.

[0007] Among them, a plurality of positioning discs are arranged in the inner wall of the outer support cover in a circular array, and a plurality of positioning discs are arranged on the side wall of the stand in a circular array. One side of the plurality of positioning discs is fixedly connected with a limiting rod. The reset spring is installed between the corresponding two positioning discs. The reset spring is sleeved outside the corresponding two limiting rods.

[0008] Among them, a hemispherical protective soft cover is installed at the top end of the outer support cover. The stand penetrates through the top of the hemispherical protective soft cover. The hemispherical protective soft cover is slidingly connected to the side wall of the stand.

[0009] Among them, a support ring is installed on the side wall of the stand. A plurality of horizontal sensors are installed at the top end of the support ring. Two audible and visual alarms electrically connected with the horizontal sensors are installed at the bottom of the connecting cover.

[0010] Among them, a conical guide soft cover is installed at the bottom end of the ball type cover. The conical guide soft cover is installed on the inner wall of the intercommunication groove.

[0011] The utility model has the advantages that the stand is connected with the connecting cover through the ball type cover, so that the stand has the ability of multidirectional inclination. The inclination ability of the stand can cope with accidental touching of personnel or mechanical equipment. When the stand is directly connected with the connecting pipe head, the connecting part is damaged, which leads to leakage of water and fertilizer solution. This not only affects normal spraying and fertilization operation, but also may cause pollution to the growth environment of crops. At the same time, the traction force of the stand on the buried water and fertilizer delivery pipe is reduced when the stand is inclined, which reduces the deformation and rupture of the buried water and fertilizer delivery pipe, and is beneficial to stable use. A plurality of reset springs cooperate to keep the support ring in a vertical state and have good restoring force, so that the stand can automatically return to normal after inclination, avoiding affecting subsequent fertilization operation.

[0012] The parts not involved in the device are the same as or can be implemented by the prior art. BRIEF DESCRIPTION OF DRAWINGS

The connecting cover 3 supports the outer supporting cover 5, the outer supporting cover 5 pushes the stand pole 2 through a plurality of reset springs 51, so that the stand pole 2 can maintain a stable vertical state without being affected by external force. When a person or an instrument accidentally knocks down the stand pole 2 during agricultural activities, the stand pole 2 drives the spherical cover 4 to incline, so that the stand pole 2 can be inclined by chance. After the contact ends, the plurality of reset springs 51 cooperatively push and pull the stand pole 2 back to the vertical state, so that the stand pole 2 can continue to work stably. This reduces damage to the connecting part when the stand pole 2 is directly connected to the connecting pipe head 11, which causes water and fertilizer solution to leak, affects normal spraying and fertilization, and may pollute the growth environment of crops. At the same time, the traction force of the stand pole 2 on the buried water and fertilizer conveying pipe 1 is reduced when the stand pole 2 is inclined, which reduces the deformation and rupture of the buried water and fertilizer conveying pipe 1, and is conducive to stable use.
