Description

Technical Field

[0001] The invention relates to the technical field of seedling raising equipment, in particular to greenhouse seedling raising equipment. Background Art

[0002] Seedling cultivation is a vital task in agricultural production. Greenhouses can provide suitable temperature, moisture, light and other conditions for seeds, reduce the impact of natural disasters such as frost, heavy rain and low temperature on the germination stage of crops, help improve the germination rate of seeds, and ensure a good start to crop growth.

[0003] In the prior art, seedlings are mostly grown in greenhouses using specially designed seedling trays. The seedling trays usually have multiple holes, each of which is used to grow a single seedling to ensure independent growth of the seedlings and avoid root entanglement. The seedling trays can be reused, but the seedling trays are laid flat on the greenhouse floor or on a horizontally arranged support, which will take up a large ground space. The space utilization rate of the greenhouse is low, and the space resources cannot be fully utilized. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a greenhouse seedling raising equipment, in which the seedling raising trays can be arranged in steps in the greenhouse, and the seedling raising trays are grouped for illumination, thereby ensuring illumination of crop seedlings and improving space utilization of the greenhouse.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a greenhouse seedling raising equipment, comprising a rotating frame, a base and a connecting rod, wherein the rotating frame is located above the base, the base is rotatably connected to one end of the rotating frame in the length direction, a lifting assembly for driving the rotating frame to rotate is installed on the base, and a plurality of seedling raising supports are arranged on the rotating frame at equal intervals along the length direction of the rotating frame.

[0006] The seedling support includes a support rod and a first support bracket, one end of the first support bracket is fixedly connected to one end of the support rod, the other end of the support rod is rotatably connected to a rotating frame, a fixing piece is fixed on the support rod, and at least two guide slides are fixedly installed below the first support bracket, each guide slide is installed with a sliding second support bracket, the sliding direction of the second support bracket is perpendicular to the rotation axis of the rotating frame, and each guide slide is installed with a push-pull electromagnet for positioning the second support bracket.

[0007] The fixing piece is rotatably connected to the connecting rod at a position away from the supporting rod.

[0008] The rotating frame is in a horizontal state, and the first supporting frame and the second supporting frame in the seedling support are both placed on the sown seedling trays.

[0009] Among them, the jacking assembly drives the rotating frame to rotate. The position of the rotating frame away from the base rotates upward, and the seedling cultivation brackets are distributed in a stepped manner on the rotating frame.

[0010] Among them, the pushing connecting rod moves forward. The connecting rod drives the first supporting bracket and the second supporting bracket to rotate forward through the fixing part and the supporting rod. One of the push-pull electromagnets in the seedling cultivation bracket releases the second supporting bracket. The projection of the first supporting bracket on the second supporting bracket becomes smaller, and the second supporting bracket extends out.

[0011] Among them, the pushing connecting rod moves backward. The connecting rod drives the first supporting bracket and the second supporting bracket to rotate backward through the fixing part and the supporting rod. The extended second supporting bracket resets, and then the push-pull electromagnet in the seedling cultivation bracket positions the second supporting bracket.

[0012] As a preferred technical solution of the present invention, a moving assembly moving along the length direction of the rotating frame is installed on the rotating frame. A rigid second conduit is fixed on the moving assembly. A plurality of nozzles are installed on the second conduit. The inner cavity of the second conduit is communicated with one end of the first conduit. A valve is installed on the first conduit.

[0013] Among them, the valve is closed. The position of the first conduit away from the second conduit is communicated with an external water pump. The external water pump supplies water to the nozzles through the first conduit and the second conduit. The nozzles spray water on the first supporting bracket or the second supporting bracket. When the second conduit moves to the highest position of the rotating frame, the external water pump stops supplying water to the first conduit, and then the valve is opened. The air outside the second conduit enters the second conduit through the nozzles.

[0014] As a preferred technical solution of the present invention, the moving assembly includes two mounting frames. Two rotating guide wheels are installed on each mounting frame. The two mounting frames are fixed on the second conduit. One of the guide wheels is made of iron or steel. A set of magnetic blocks is installed on the rotating frame at the position corresponding to each seedling cultivation bracket. The sum of the numbers of the first supporting bracket and the second supporting bracket in the seedling cultivation bracket is equal to the number of magnetic blocks in a set of magnetic blocks.

[0015] Among them, when the magnetic blocks are magnetically attracted to the guide wheels made of iron or steel, the nozzles on the second conduit are aligned with the first supporting bracket or the second supporting bracket.

[0016] As a preferred technical solution of the present invention, a spiral rod is arranged in the inner cavity of the second conduit, and a sponge is arranged in the spiral rod.

[0017] As a preferred technical solution of the present invention, an installation hole communicating with the highest point of the inner cavity of the second conduit is opened on the second conduit, and an automatic exhaust valve is installed on the installation hole.

[0018] As a preferred technical solution of the present invention, one of the guide wheels in the moving assembly is a hub motor.

[0019] As a preferred technical solution of the present invention, a sliding member is fixed to one end of the connecting rod. A clamping groove is formed on the sliding member. The rotating frame passes through the clamping groove. A threaded hole is formed on the sliding member, and a bolt is installed on the threaded hole.

[0020] As a preferred technical solution of the present invention, the number of guiding sliding frames in the seedling-raising support is two.

[0021] As a preferred technical solution of the present invention, clamping holes for clamping the seedling-raising trays are formed on both the first supporting bracket and the second supporting bracket.

[0022] As a preferred technical solution of the present invention, a limiting block is fixed on each second supporting bracket of the seedling-raising support.

[0023] Among them, after one of the second supporting brackets of the seedling-raising support extends out, the limiting block on this second supporting bracket contacts the push-pull electromagnet.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. For the greenhouse seedling-raising equipment of the present invention example, the seeded seedling-raising trays are fixedly placed on both the first supporting bracket and the second supporting bracket in the seedling-raising support, and the seedling-raising supports are arranged in a stepped manner on the rotating frame: on the one hand, the second supporting bracket on the seedling-raising support can extend out and reset, so that the crop seedlings on the first supporting bracket and the crop seedlings on the second supporting bracket can both receive light, improving the space utilization rate of the greenhouse; on the other hand, when the nozzle is blocked by impurities in the water and cannot discharge water, the worker moves the second conduit to the highest position of the rotating frame, the external water pump stops supplying water to the first conduit, and then the valve is opened. The second conduit is in negative pressure, and the air outside the second conduit enters the second conduit through the nozzle. The flowing air in the nozzle makes the impurities in the nozzle enter the second conduit, and it is convenient to clean the blocked nozzle; on the further hand, a spiral rod is arranged in the inner cavity of the second conduit, a sponge is arranged in the spiral rod, the flowing air in the nozzle makes the impurities in the nozzle enter the second conduit, and the impurities are stuck in the gap holes of the sponge, reducing the number of impurities that can move freely in the second conduit and reducing the risk of nozzle blockage.

[0026] 2. For the greenhouse seedling-raising equipment of the present invention example, the worker pushes the second conduit through the external support rod, and the guide wheel rolls along the length direction of the rotating frame. When the magnetic block and the guide wheel are magnetically attracted, the nozzle on the second conduit is aligned with the first supporting bracket or the second supporting bracket, realizing accurate watering of the crop seedlings on the first supporting bracket or the crop seedlings on the second supporting bracket, and reducing water resource waste.

[0027] 3. In the greenhouse seedling raising equipment of the present invention example, a moving component is installed on the rotating frame and moves along the length direction of the rotating frame. Workers push the second conduit along the length direction of the rotating frame through the moving component to water the crop seedlings on the first supporting bracket or the crop seedlings on the second supporting bracket, which has a lower cost compared to arranging watering pipes on both the first supporting bracket and the second supporting bracket.

[0028] 4. In the greenhouse seedling raising equipment of the present invention example, workers push the seedling raising bracket to rotate through the connecting rod, so that the sunlight vertically irradiates the crop seedlings, and then fix the sliding part on the rotating frame through bolts to maintain the best sunlight irradiation angle of the crop seedlings.

[0029] 5. In the greenhouse seedling raising equipment of the present invention example, workers push the connecting rod to move back and forth to accelerate the air flow at the crop seedlings on the seedling raising bracket. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] Embodiment 1:

[0039] See also Figures 1-5 The present embodiment discloses a greenhouse seedling raising equipment, comprising a rotating frame 1, a base 4 and a connecting rod 8. The rotating frame 1 is located above the base 4. The top side of the base 4 and one end of the rotating frame 1 in the length direction are connected through a bearing or a hinge. A lifting component 3 for driving the rotating frame 1 to rotate is installed on the base 4. A plurality of seedling raising supports 2 are arranged on the rotating frame 1 at equal intervals along the length direction of the rotating frame 1.

[0040] The seedling support 2 includes a support rod 21 and a first support bracket 23, one end of the first support bracket 23 is fixedly connected to one end of the support rod 21, the other end of the support rod 21 is connected to the rotating frame 1 through a bearing or a rotating pin, a fixing part 22 is fixed on the support rod 21, and no less than two guide slides 27 are fixedly installed below the first support bracket 23, each guide slide 27 is installed with a sliding second support bracket 24, the sliding direction of the second support bracket 24 is perpendicular to the rotation axis of the rotating frame 1, each guide slide 27 is installed with a push-pull electromagnet 26 for positioning the second support bracket 24, and the first support bracket 23 and the second support bracket 24 are arranged in parallel.

[0041] The position of the fixing member 22 away from the supporting rod 21 is connected to the connecting rod 8 via a bearing or a hinge seat.

[0042] Preferably, the number of guide slides 27 in the seedling raising support 2 is two.

[0043] Furthermore, the jacking assembly 3 is a rack jack, a screw jack or a hydraulic jack.

[0044] Furthermore, the push-pull electromagnet 26 is electrically connected to an external control switch group.

[0045] The push-pull electromagnet 26 used in the present invention is a common electronic component in the prior art, and its working method and circuit structure are well-known technologies and will not be described in detail here.

[0046] The working process and principle of this embodiment are:

[0047] Initially, the worker operates the lifting assembly 3 to make the rotating frame 1 in a horizontal state, and the second supporting bracket 24 is directly below the first supporting bracket 23. The worker fixedly places the sown seedling trays on both the first supporting bracket 23 and the second supporting bracket 24 in the seedling-raising bracket 2. Then the worker operates the lifting assembly 3 to drive the rotating frame 1 to rotate. The position of the rotating frame 1 away from the base 4 rotates upward. The seedling-raising brackets 2 are distributed in a stepped manner on the rotating frame 1. At this time, the projections of the seedling-raising brackets 2 in the vertical plane do not overlap, and the light of sunlight or artificial light source shines on the crop seedlings on the first supporting bracket 23.

[0048] The worker pushes the connecting rod 8 to move forward, and the connecting rod 8 drives the first supporting bracket 23 and the second supporting bracket 24 to rotate forward through the fixing member 22 and the support rod 21. A push-pull electromagnet 26 in the seedling-raising bracket 2 releases the second supporting bracket 24. The projection of the first supporting bracket 23 on this second supporting bracket 24 becomes smaller. This second supporting bracket 24 extends out, and this second supporting bracket 24 remains in sliding connection with the guiding sliding frame 27. This second supporting bracket 24 blocks the first supporting bracket 23 adjacent to its lower side, and the light of sunlight or artificial light source shines on the crop seedlings on the extended second supporting bracket 24.

[0049] The worker pushes the connecting rod 8 to move backward, and the connecting rod 8 drives the first supporting bracket 23 and the second supporting bracket 24 to rotate backward through the fixing member 22 and the support rod 21. The extended second supporting bracket 24 resets, and then the push-pull electromagnet 26 in the seedling-raising bracket 2 positions this second supporting bracket 24.

[0050] The second supporting bracket 24 on the seedling-raising bracket 2 can extend out and reset, enabling the crop seedlings on both the first supporting bracket 23 and the second supporting bracket 24 to receive light, improving the space utilization rate of the greenhouse.

[0051] Furthermore, the worker pushes the connecting rod 8 to reciprocate forward and backward, accelerating the air flow at the positions of the crop seedlings on the seedling-raising bracket 2.

[0052] As Figure 1 shown, the first supporting bracket 23 is parallel to the horizontal plane.

[0053] As Figure 4 shown, the included angle between the first supporting bracket 23 and the horizontal plane is 2° - 30°.

[0054] Embodiment 2:

[0055] As Figure 1 、 Figure 4As shown in the figure, this embodiment discloses a greenhouse seedling raising device, whose structure is roughly the same as that of the first embodiment. The difference is that a moving component that moves along the length direction of the rotating frame 1 is installed on the rotating frame 1 of this embodiment. A rigid second conduit 7 is fixed on the moving component, and a number of nozzles 11 are installed on the second conduit 7. One end of the inner cavity of the second conduit 7 communicates with the first conduit 5, and a valve 6 is installed on the first conduit 5.

[0056] The working process and principle of this embodiment are as follows:

[0057] The worker closes the valve 6. The position of the first conduit 5 far from the second conduit 7 is connected to an external water pump. The external water pump supplies water to the nozzles 11 through the first conduit 5 and the second conduit 7. The nozzles 11 spray water on the first supporting bracket 23 or the second supporting bracket 24. The worker pushes the second conduit 7 to move along the length direction of the rotating frame 1 through an external support rod or an external driving mechanism, so as to water the crop seedlings on the first supporting bracket 23 or the crop seedlings on the second supporting bracket 24. Compared with arranging watering pipes on both the first supporting bracket 23 and the second supporting bracket 24, the cost is lower.

[0058] When the nozzles 11 are blocked by impurities in the water and cannot discharge water, the worker moves the second conduit 7 to the highest position of the rotating frame 1, the external water pump stops supplying water to the first conduit 5, and then the valve 6 is opened. The water in the first conduit 5 flows downward, making the second conduit 7 in negative pressure. The air outside the second conduit 7 enters the second conduit 7 from the nozzles 11, and the flowing air in the nozzles 11 drives the impurities in the nozzles 11 into the second conduit 7. It is convenient to clean the nozzles 11 after being blocked.

[0059] Embodiment Three:

[0060] As Figure 1 、 Figure 3 shown in the figure, this embodiment discloses a greenhouse seedling raising device, whose structure is roughly the same as that of the second embodiment. The difference is that the moving component of this embodiment includes two mounting frames 13. Two guide wheels 12 are installed on each mounting frame 13 through bearings. The two mounting frames 13 are fixed on the second conduit 7. One of the guide wheels 12 is made of iron or steel. A set of magnetic blocks 15 is installed at the position corresponding to each seedling raising bracket 2 on the rotating frame 1. The sum of the numbers of the first supporting bracket 23 and the second supporting bracket 24 in the seedling raising bracket 2 is equal to the number of magnetic blocks 15 in a set of magnetic blocks 15.

[0061] The working process and principle of this embodiment are as follows:

[0062] The worker pushes the second conduit 7 through an external support rod. The guide wheel 12 rolls along the length direction of the rotating frame 1. When the magnetic block 15 and the guide wheel 12 are magnetically attracted, the nozzle 11 on the second conduit 7 aligns with the first support bracket 23 or the second support bracket 24, realizing precise watering of the crop seedlings on the first support bracket 23 or the second support bracket 24, and reducing water resource waste.

[0063] Embodiment 4:

[0064] As Figure 6 shown, this embodiment discloses a greenhouse seedling raising device, whose structure is substantially the same as that of Embodiment 2 or Embodiment 3. The difference is that a screw rod 17 is arranged in the inner cavity of the second conduit 7 in this embodiment, and a sponge 16 is arranged inside the screw rod 17.

[0065] In the prior art, the surface of the sponge 16 has densely distributed gap holes.

[0066] The working process and principle of this embodiment are:

[0067] The screw rod 17 supports the sponge 16 to prevent the sponge 16 from affecting the water inlet of the nozzle 11.

[0068] When the nozzle 11 is blocked by impurities in the water and cannot discharge water, after the second conduit 7 moves to the highest position of the rotating frame 1, the external water pump stops supplying water to the first conduit 5. Then the worker opens the valve 6, and the water in the first conduit 5 flows downward, creating negative pressure in the second conduit 7. The air outside the second conduit 7 enters the second conduit 7 through the nozzle 11, and the flowing air in the nozzle 11 makes the impurities in the nozzle 11 enter the second conduit 7. The impurities are stuck in the gap holes of the sponge 16, reducing the number of impurities that can move freely in the second conduit 7 and reducing the risk of blockage of the nozzle 11.

[0069] Embodiment 5:

[0070] As Figure 3 shown, this embodiment discloses a greenhouse seedling raising device, whose structure is substantially the same as that of Embodiment 2. The difference is that an installation hole communicating with the highest point of the inner cavity of the second conduit 7 is opened on the second conduit 7, and an automatic exhaust valve 14 is installed on the installation hole.

[0071] The working process and principle of this embodiment are:

[0072] During the continuous water inlet process in the second conduit 7, the air in the second conduit 7 is discharged through the automatic exhaust valve 14.

[0073] The automatic exhaust valve 14 is a common valve in prior art HVAC equipment, which can discharge the gas in the pipeline and prevent the liquid in the pipeline from discharging.

[0074] Embodiment 6:

[0075] As Figure 3 shown, this embodiment discloses a greenhouse seedling raising device, whose structure is substantially the same as that of the third embodiment. The difference is that one of the guide wheels 12 in the moving component of this embodiment is a hub motor, and the hub motor is electrically connected to an external control switch group.

[0076] The working process and principle of this embodiment are as follows:

[0077] The worker energizes the hub motor to rotate, and the hub motor drives the second conduit 7 to move along the length direction of the rotating frame 1 through the mounting frame 13, eliminating the need for the worker to push the second conduit 7 and reducing the worker's labor intensity.

[0078] Embodiment Seven:

[0079] As Figure 2 shown, this embodiment discloses a greenhouse seedling raising device, whose structure is substantially the same as that of the first embodiment. The difference is that one end of the connecting rod 8 in this embodiment is fixed with a sliding member 9, a clamping groove is formed on the sliding member 9, the rotating frame 1 passes through the clamping groove, and a screw hole is formed on the sliding member 9, and a bolt 10 is installed on the screw hole.

[0080] The working process and principle of this embodiment are as follows:

[0081] The worker pushes the seedling raising support 2 to rotate through the connecting rod 8 to make the sunlight vertically irradiate the crop seedlings. Then the worker rotates the bolt 10 to make the bolt 10 abut against the rotating frame 1, so that the crop seedlings on the first supporting bracket 23 or the second supporting bracket 24 adapt to the sun at different heights and maintain the best sunlight irradiation angle for the crop seedlings.

[0082] Embodiment Eight:

[0083] As Figure 1 、 Figure 4 and Figure 5 shown, this embodiment discloses a greenhouse seedling raising device, whose structure is substantially the same as that of the first embodiment. The difference is that both the first supporting bracket 23 and the second supporting bracket 24 in this embodiment are provided with clamping holes for clamping the seedling tray, making it convenient and firm to fix the seedling tray.

[0084] Embodiment Nine:

[0085] As Figure 5 shown, this embodiment discloses a greenhouse seedling raising device, whose structure is substantially the same as that of the first embodiment. The difference is that a limiting block 25 is fixed on each second supporting bracket 24 of the seedling raising support 2 in this embodiment.

[0086] After one of the second supporting brackets 24 of the seedling raising support 2 extends out, the limiting block 25 on the second supporting bracket 24 contacts the push-pull electromagnet 26 to prevent the second supporting bracket 24 from disengaging from the guiding slide 27.

[0087] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
