Description

Technical Field

[0001] The invention relates to the technical field of nursery beds, in particular to a temperature-controlled ground cover plant nursery bed. Background Art

[0002] At present, greenhouse seedling technology is usually used in the seedling stage of plants. The application of greenhouse seedling technology has reduced the impact of harsh environments such as low temperature and strong wind on seedling cultivation.

[0003] Greenhouse seedling cultivation can make full use of the autumn and winter periods to supply seedlings for open-field planting in the spring. The greenhouse is usually composed of many seedling beds. Wide operating channels need to be left between adjacent seedling beds to facilitate workers' operations. This occupies a large space, reducing the effective utilization area of ​​the greenhouse. In addition, since multiple seedling beds are in the same greenhouse, they can only cultivate plant varieties with the same or similar required conditions, which is very limited during use and has poor practicality.

[0004] Therefore, a temperature-controlled ground cover plant nursery bed is needed. Summary of the invention

[0005] In order to solve all or part of the above problems, the purpose of the present invention is to provide a temperature-controlled ground cover plant seedling bed to solve the problem proposed in the above-mentioned comparative document technology that a very wide operating channel needs to be reserved between adjacent seedling beds to facilitate workers' operation, which occupies a large space and increases the cost of use.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a temperature-controlled ground cover plant seedling bed, comprising a bracket, a seedling bed 1 is arranged on one side of the upper end of the bracket, a seedling bed 2 is arranged on the other side of the upper end of the bracket, convenient components are arranged on the outer sides of the seedling bed 1 and the seedling bed 2, seedling trays are arranged inside the seedling bed 1 and the seedling bed 2, the seedling bed 1 and the seedling bed 2 have exactly the same structural composition, two groups of constant temperature mechanisms are fixedly installed on the upper end of the seedling bed 1, the convenient components include a driving mechanism and two groups of driven parts located on both sides of the driving mechanism and symmetrically meshed, the output end of the driving mechanism is meshedly connected with two groups of transmission parts, the end of the transmission part away from the driving mechanism is meshedly connected with a laying and receiving part, the laying and receiving part is fixedly connected to the constant temperature mechanism, and in the initial state, the seedling bed 1 and the seedling bed 2 are spread out by the constant temperature mechanism to The interior is isolated from the outside world, thereby reducing the rate of internal heat loss to achieve a constant temperature effect. When personnel need to operate the inside of seedling bed 1 and seedling bed 2, the driving mechanism drives the two groups of followers to move horizontally in opposite directions. The two groups of followers drive seedling bed 1 and seedling bed 2 to move horizontally in opposite directions during the movement, thereby forming a channel between seedling bed 1 and seedling bed 2 for personnel to pass and operate. At the same time, the driving mechanism drives the laying and collecting parts to rotate through the transmission parts, so that the constant temperature mechanism is rolled up, so that personnel can operate from both sides of seedling bed 1 and seedling bed 2, which greatly facilitates the operation of personnel. When the driving mechanism is driven in the reverse direction, seedling bed 1 and seedling bed 2 are brought together again to reduce space occupancy, and the constant temperature mechanism is spread out again to achieve a constant temperature effect.

[0007] Furthermore, the driving mechanism includes a servo motor fixedly connected to the bracket, a rotating shaft is fixedly installed on the output end of the servo motor, and a gear is fixedly installed on the outer side of the rotating shaft;

[0008] The two groups of follower structures are exactly the same. The follower includes an L block and a rack located on one side of the L block and fixedly connected. The rack is meshed with the gear. The two groups of L blocks are respectively fixedly connected to the seedling bed one and the seedling bed two. The servo motor drives the rotating shaft to rotate and drives the gear to rotate, thereby driving the two groups of L blocks to move horizontally in opposite directions and at the same time drive the seedling bed one and the seedling bed two to move horizontally in opposite directions, thereby forming an aisle between them.

[0009] Furthermore, a bevel gear 1 is fixedly installed at one end of the rotating shaft away from the servo motor, and the two groups of transmission parts have exactly the same structural composition. The transmission part includes a telescopic rod and a bevel gear 2 located at one end of the telescopic rod and fixedly connected. The bevel gear 2 is meshingly connected to the bevel gear 1. The two groups of telescopic rods are respectively rotatably connected to the seedling bed 1 and the seedling bed 2. The rotating shaft also drives the bevel gear 1 to rotate during the rotation process. Since the bevel gear 2 is in a meshing state with the bevel gear 1, the transmission part is driven to rotate as a whole.

[0010] Furthermore, a bevel gear three is fixedly installed on the other end of the telescopic rod, and the two sets of paving and receiving components have exactly the same structural composition. The paving and receiving components include a fixed block and a driven rod that penetrates the fixed block and is rotatably connected. The two sets of fixed blocks are respectively fixedly connected to the seedling bed one and the seedling bed two. A bevel gear four is fixedly installed on one end of the driven rod, and the bevel gear four is meshedly connected with the bevel gear three. Multiple sets of rubber pull belts are rolled up on the outer side of the driven rod, and one end of the rubber pull belt is fixedly connected to the driven rod;

[0011] The two sets of constant temperature mechanisms have exactly the same structural composition. The constant temperature mechanism includes a rotating rod and a film sleeved on the outside of the rotating rod. Both ends of the film are fixedly installed with cross bars. The cross bar at one end of the film is fixedly connected to the rotating rod, and the other end of the rubber pull belt is fixedly connected to the cross bar at the other end of the film. Both ends of the rotating rod are rotatably installed with fixing parts. The two sets of fixing parts are respectively fixedly connected to the seedling bed one and the seedling bed two. Fixed rings are fixedly installed on the outside of both ends of the rotating rod. Two sets of torsion springs are sleeved on the outside of the rotating rod. One end of the torsion spring is fixedly connected to the fixing ring, and the other end of the torsion spring is fixedly connected to the fixing part. The upper end of the seedling bed one A plurality of arc frames are fixedly installed, and grooves are provided on the surfaces of the arc frames. A plurality of groups of rubber drawstrings are paired with the plurality of grooves and are slidably connected. During the rotation, the telescopic rod meshes with the bevel gear three through the bevel gear four, thereby driving the driven rod to rotate to unwind the rubber drawstring. Since the torsion spring is in a torsion state in the initial state, the torsion spring is reset at this time and drives the rotating rod to rotate through the fixed ring to rewind the film, so that personnel can operate from both sides of the seedling bed one and the seedling bed two, which greatly facilitates the operation of the personnel. Similarly, when the servo motor is reversed, the film can be spread out again.

[0012] Furthermore, a spring is fixedly installed at one end of the L block, and a connecting rod is fixedly installed at one end of the spring away from the L block. The two sets of connecting rods are respectively fixedly connected to the seedling bed one and the seedling bed two. When the seedling bed one and the seedling bed two move horizontally in opposite directions, the spring is stretched by the L block and the connecting rod. When the personnel operation is completed, the servo motor starts to reverse. Due to the restoring force of the spring, the rack is meshed with the gear again, so that the seedling bed one and the seedling bed two move horizontally in the direction of approaching each other, and then return to the initial position.

[0013] Furthermore, a slider is fixedly installed at the lower end of the seedling bed, and a slide groove is opened on the upper surface of the bracket. The slider is slidably connected to the slide groove. The stability of the device during operation is further improved by the synchronous sliding of the slider in the slide groove.

[0014] Furthermore, a positioning groove is provided on the inner wall surface of the seedling bed 1, and the seedling tray includes a partition 1 and a partition 2 which fit with the positioning groove and are slidably connected. The partition 1 and the partition 2 are slidably connected. The positioning groove facilitates the quick placement and fixation of the partition 1 and the partition 2. At the same time, the number of the partition 1 and the partition 2 can be adjusted according to the space occupied by the plants, thereby further improving the scope of use.

[0015] Furthermore, a heating wire is fixedly installed inside the seedling bed one, and a spray mechanism is fixedly installed inside the seedling bed one. The spray mechanism includes a water pipe that passes through the seedling bed one and is fixedly connected, a plurality of nozzles are fixedly installed below the water pipe, and a flange is fixedly installed at one end of the water pipe. The heating of the heating wire provides the required heat source inside, and the water pipe is quickly connected to the water supply pipeline through the flange, and then sprayed out through the nozzle to maintain the required humidity requirement.

[0016] Furthermore, fans are fixedly installed at both ends of the nursery bed. Through the setting of the fans, the air inside and outside is exchanged to a certain extent to avoid the accumulation of carbon dioxide and the death of the seedlings.

[0017] Furthermore, a filter screen fixedly connected to the nursery bed is provided on one side of the fan, and the setting of the filter screen can effectively prevent the entry of impurities in the outside air.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention provides a temperature-controlled ground cover plant seedling bed, which is spread out in an initial state through a constant temperature mechanism to isolate the interior of the seedling bed one and the seedling bed two from the outside world, thereby reducing the internal heat loss rate to achieve a constant temperature effect. When personnel need to operate the interior of the seedling bed one and the seedling bed two, the driving mechanism drives the two groups of driven members to move horizontally in opposite directions. During the movement, the two groups of driven members drive the seedling bed one and the seedling bed two to move horizontally in opposite directions, thereby forming a passage between the seedling bed one and the seedling bed two for personnel to pass through and operate. At the same time, the driving mechanism drives the laying and collecting members to rotate through the transmission member, so that the constant temperature mechanism is rolled up, so that personnel can operate from both sides of the seedling bed one and the seedling bed two, which greatly facilitates the operation of personnel, and when the driving mechanism is driven in the reverse direction, the seedling bed one and the seedling bed two are brought together again to reduce the space occupancy, and the constant temperature mechanism is spread out again to achieve a constant temperature effect.

The seedling bed 2 and the seedling bed 2 3 have the same structural composition, and two groups of constant temperature mechanisms 28 are fixedly installed on the upper end of the seedling bed 2. The convenient component 4 includes a driving mechanism 41 and two groups of driven members 42 located on both sides of the driving mechanism 41 and symmetrically meshed and connected. The output end of the driving mechanism 41 is meshed and connected with two groups of transmission members 43, and the end of the transmission member 43 away from the driving mechanism 41 is meshed and connected with a paving and receiving member 44, and the paving and receiving member 44 is fixedly connected to the constant temperature mechanism 28. In the initial state, the constant temperature mechanism 28 is spread out to connect the interior of the seedling bed 2 and the seedling bed 2 3. The outside world is isolated, thereby reducing the rate of internal heat loss to achieve a constant temperature effect. When personnel need to operate the inside of seedling bed 1 2 and seedling bed 2 3, the driving mechanism 41 drives the two groups of follower members 42 to move horizontally in opposite directions. The two groups of follower members 42 drive seedling bed 1 2 and seedling bed 2 3 to move horizontally in opposite directions during the movement, thereby forming a channel between seedling bed 1 2 and seedling bed 2 3 for personnel to pass and operate. At the same time, the driving mechanism 41 drives the laying and collecting member 44 to rotate through the transmission member 43, so that the constant temperature mechanism 28 is rolled up, so that personnel can operate from both sides of seedling bed 1 2 and seedling bed 2 3, which greatly facilitates the operation of personnel. When the driving mechanism 41 is driven in the reverse direction, seedling bed 1 2 and seedling bed 2 3 are brought together again to reduce space occupancy, and the constant temperature mechanism 28 is spread out again to achieve a constant temperature effect.

[0033] Combination Figure 6-7 The driving mechanism 41 includes a servo motor 411 fixedly connected to the bracket 1, a rotating shaft 412 is fixedly installed on the output end of the servo motor 411, and a gear 414 is fixedly installed on the outer side of the rotating shaft 412;

The two groups of L blocks 421 are respectively fixedly connected to the seedling bed 1 2 and the seedling bed 2 3. The servo motor 411 drives the rotating shaft 412 to rotate and drives the gear 414 to rotate, thereby driving the two groups of L blocks 421 to move horizontally in opposite directions and at the same time drive the seedling bed 1 2 and the seedling bed 2 3 to move horizontally in opposite directions, thereby forming an aisle between them.

[0035] Combination Figure 7-8A bevel gear 1 413 is fixedly installed at one end of the rotating shaft 412 away from the servo motor 411. The structures of the two sets of transmission parts 43 are exactly the same. The transmission part 43 includes a telescopic rod 431 and a bevel gear 2 432 located at one end of the telescopic rod 431 and fixedly connected. The bevel gear 2 432 is meshed and connected with the bevel gear 1 413. The two sets of telescopic rods 431 are rotatably connected with the seedling bed 1 2 and the seedling bed 2 3 respectively. The rotating shaft 412 drives the bevel gear 1 413 to rotate during the rotation process. Because the bevel gear 2 432 is in a meshing state with the bevel gear 1 413, the transmission part 43 is driven to rotate as a whole.

[0036] Combination Figure 5-6 , Figure 8 , the other end of the telescopic rod 431 is fixedly installed with a bevel gear three 433, and the two groups of paving and receiving parts 44 have exactly the same structure. The paving and receiving parts 44 include a fixed block 441 and a driven rod 442 that penetrates the fixed block 441 and is rotatably connected. The two groups of fixed blocks 441 are respectively fixedly connected to the seedling bed 1 2 and the seedling bed 2 3, and one end of the driven rod 442 is fixedly installed with a bevel gear four 443, which is meshed with the bevel gear three 433. The outer side of the driven rod 442 is rolled up with multiple groups of rubber pull belts 444, and one end of the rubber pull belt 444 is fixedly connected to the driven rod 442;

[0037] The two sets of thermostatic mechanisms 28 have the same structural composition. The thermostatic mechanism 28 includes a rotating rod 281 and a film 282 sleeved on the outside of the rotating rod 281. Both ends of the film 282 are fixedly installed with cross bars 283. The cross bar 283 at one end of the film 282 is fixedly connected to the rotating rod 281. The other end of the rubber pull belt 444 is fixedly connected to the cross bar 283 at the other end of the film 282.

A plurality of groups of rubber pull belts 444 are connected to the plurality of grooves 24 one by one and are slidably connected. The telescopic rod 431 is meshed with the bevel gear three 433 through the bevel gear four 443 during rotation, thereby driving the driven rod 442 to rotate and unwind the rubber pull belt 444. Since the torsion spring 286 is in a torsion state in the initial state, the torsion spring 286 is reset at this time and drives the rotating rod 281 to rotate through the fixed ring 284 to rewind the film 282, so that personnel can operate from both sides of the seedling bed 1 2 and the seedling bed 2 3, which greatly facilitates the operation of the personnel. Similarly, when the servo motor 411 is reversed, the film 282 can be spread out again.

The two sets of connecting rods 424 are fixedly connected to the seedling bed 1 2 and the seedling bed 2 3 respectively. When the seedling bed 1 2 and the seedling bed 2 3 move horizontally in opposite directions, the spring 423 is stretched by the L block 421 and the connecting rod 424. When the personnel operation is completed, the servo motor 411 starts to reverse. Due to the reset force of the spring 423, the rack 422 is meshed with the gear 414 again, so that the seedling bed 1 2 and the seedling bed 2 3 move horizontally in the direction of approaching each other, and then return to the initial position.
