[0001] The invention relates to a device for low-temperature vernalization of vegetables, in particular to a device for accelerating the low-temperature vernalization of broccoli and carrots, which is applied to the field of vegetable cultivation. Background Art

[0002] During the cultivation process, broccoli and carrot vegetables need to be subjected to low-temperature vernalization treatment before they can normally bolt and bloom. During the low-temperature vernalization operation, a low-temperature incubator is usually used to provide low temperature. Currently, manual operation is generally used to place the seedlings and potted plants to be treated with low-temperature vernalization in the low-temperature incubator, resulting in a large amount of manual labor.

[0003] The specification of Chinese invention patent CN202110922474.1 discloses a vernalization cultivation device for broccoli seedlings. The application sets a lifting mechanism and a clamping mechanism connected to the lifting mechanism in a box body. The clamping mechanism can clamp and fix the mounting seat for holding the cultivation box. The lifting mechanism drives the clamping mechanism to move so that the mounting seat can be moved out of or into the box body, which is convenient for putting in and taking out the broccoli seedlings. It is easy to operate and has good practicality.

[0004] When existing vernalization cultivation devices use mechanical structures to take out and put in seedlings to be vernalized to reduce manual labor, the mechanical structures occupy a certain amount of space, resulting in a reduction in the utilization rate of the limited low-temperature vernalization incubator space. In addition, if a forklift is used to achieve mechanized material retrieval, certain size requirements will be placed on the external space of the low-temperature incubator. However, in actual operation, the low-temperature vernalization incubators are usually arranged in a crowded manner, making it difficult to meet the space requirements when the forklift is moving. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to maximize the space utilization in the low-temperature incubator and simplify the manual labor on the basis of intelligent accelerated low-temperature vernalization.

[0008] Fill lights are installed at the bottom of the movable plate and the top of the incubator. A pull-out rod is arranged in the middle of the upper and lower side panels. A ring is fixedly sleeved on the surface of the pull-out rod, and the ring and the surfaces of the two side panels adjacent in the vertical direction are connected to movable parts through shafts, and the tail end of the pull-out rod is slidably connected to the inside of the docking rail.

[0009] In the above-mentioned device for accelerating the low-temperature vernalization of broccoli and carrots, on the basis of intelligently accelerating the low-temperature vernalization, the space utilization rate in the low-temperature incubator is maximized and the manual labor is simplified.

[0010] As a further improvement of the present application, the output end of the winding motor is connected to a winding roller, and a winding rope is wound around the surface of the winding roller, and the tail end of the winding rope is connected to the top surface of the uppermost side panel.

[0011] As a further improvement of the present application, the ends of the No. 1 shaft and the No. 2 shaft are both rotatably plugged into the surface of the side plate, and in the initial state, the sum of the lengths of the two No. 2 shafts and the compression spring is greater than the length of the No. 1 shaft.

[0012] As a further improvement of the present application, the cross section of the movable part in the initial state is V-shaped, and the tip of the cross section of the movable part in the initial state faces the front of the incubator.

[0013] As a further improvement of the present application, an intercepting plate is connected to the rear of the top surface of the uppermost movable plate, and the cross-sectional width of the movable plate is smaller than the cross-sectional width of the interior of the incubator.

[0014] As a further improvement of the present application, a PLC intelligent control system is also included, which includes a control processor installed on the surface of the sealed door panel, the control processor includes a state monitoring module, an adjustment execution module and an auxiliary pick-up and delivery module, wherein the state monitoring module is connected to the temperature and humidity sensor, the CO2 sensor and the light sensor signal, and is used to monitor the temperature and humidity, CO2 concentration and light environment conditions in the incubator;

The electromagnetic rod is activated to make the second shaft rod separate from the side plate. Manual operation deflects the movable plate to facilitate the entry of the plant and slide down by gravity, and cooperates with the pleated spring to ensure the safety of the plant.

[0035] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0036] The first implementation method:

[0037] Figure 1-2 A device for accelerating the low-temperature vernalization of broccoli and carrots is shown. The device includes an incubator 1 with built-in temperature and humidity sensors, a CO2 sensor, and a light sensor. A sealed door panel is installed on the front of the incubator 1. A refrigerator 3 and a winding motor 2 located on one side of the refrigerator 3 are installed on the top of the incubator 1. The refrigerator 3 is electrically connected to the temperature and humidity sensor. The output end of the refrigerator 3 is connected to a hose extending into the incubator 1. Symmetrical docking rails 11 are installed on the rear wall of the incubator 1. A vertically arranged pad 12 is connected to the bottom of the docking rail 11. A plurality of equally spaced movable partition units 4 are arranged above the pad 12.

[0038] Figure 3 It is shown that each movable partition unit 4 includes two side panels 41 and a movable panel 42 located between the two side panels 41. A receiving groove is provided at the rear position of the top surface of the movable panel 42, and a pleated spring piece 7 is connected to the inside of the receiving groove, and the top of the pleated spring piece 7 is respectively connected to the surfaces of the two side panels 41 close to each other. A No. 1 shaft rod 43 is installed at the center position inside the movable panel 42. A swing assist unit is installed inside the movable panel 42. The swing assist unit includes two No. 2 shaft rods 44, and the ends of the two No. 2 shaft rods 44 close to each other are connected by a compression spring 46. The surfaces of the two No. 2 shaft rods 44 close to each other are connected to electromagnetic rods 45 that attract each other. A movable groove is provided on the front of the movable panel 42, and the electromagnetic rod 45 is slidably connected to the inside of the movable groove.

[0039] Figure 5 It is shown that fill lights 6 are installed at the bottom of the movable plate 42 and the top of the incubator 1, and a pull-out rod 5 is arranged in the middle of the upper and lower side panels 41. A circular ring is fixedly sleeved on the surface of the pull-out rod 5, and the circular ring and the surfaces of the two vertically adjacent side panels 41 are connected to movable parts 51 through shafts, and the tail end of the pull-out rod 5 is slidably connected to the inside of the docking rail 11.

[0040] The output end of the winding motor 2 is connected to a winding roller, and a winding rope 21 is wound around the surface of the winding roller. The tail end of the winding rope 21 is connected to the top surface of the uppermost side plate 41 .

[0041] Specifically, since the incubator 1 has a certain height, when the plants to be subjected to low-temperature vernalization are placed in the incubator 1, they need to be lifted or bent over, which makes the manual labor more cumbersome. To improve this phenomenon, this embodiment is adopted;

[0042] When the plants are sent into the cultivation box 1, the multiple movable partition units 4 in the folded and compressed state can be lifted by the winding motor 2 and the winding rope 21, so that the lowest movable partition unit 4 is at a certain position in the cultivation box 1 (this position can be adjusted according to the height of the operator, which is convenient for the operator to stand and operate without lifting or bending). Then, the pulling rod 5 above the lowest movable partition unit 4 is pushed toward the rear wall of the cultivation box 1 into the insertion rail 11, so that the movable part 51 stands up, thereby forming a partition space to accommodate the plants for accelerated vernalization treatment;

[0043] Figure 6-7 As shown, when placing, the electromagnetic rod 45 in the lowest movable plate 42 is first started, so that the two electromagnetic rods 45 are close to each other, so that the second shaft rod 44 is close to each other, and after the plug-in constraint effect with the side plate 41 is lost, the operator manually toggles the movable plate 42 so that the movable plate 42 can be deflected inwardly under the action of the first shaft rod 43. At this time, the pleated spring piece 7 on the surface of the lowest movable plate 42 is stretched (because the end of the pleated spring piece 7 is connected to the surface of the side plate 41, when the movable plate 42 is tilted toward the rear wall of the incubator 1, the pleated spring piece 7 will form an interception structure, and when the movable plate 42 is tilted toward the front of the incubator 1, it can play a corresponding limiting effect, preventing the movable plate 42 from tilting too much and causing the plants at the rear position of the movable plate 42 to be lifted too high and squeezed into contact with the bottom wall of the upper movable plate 42, thereby protecting the plants), so that the inclined movable plate 42 can be conveniently transported (the plants can reach the rear position of the movable plate 42 by gravity without human push, such as Figure 4 The plants (shown) will not be hit by the rear wall of the incubator 1, ensuring the safety of the plants. After the surface of the lowest movable plate 42 is filled with plants, the operator manually resets the movable plate 42 to a horizontal state and turns off the electromagnetic rod 45, allowing the second shaft 44 to be re-inserted into the interior of the side plate 41, so that the movable plate 42 is restored to a horizontal state.

[0044] After the bottom movable partition unit 4 completes the convenient feeding, the winding motor 2 releases part of the winding rope 21, causing the penultimate movable partition unit 4 to fall, and repeat the above operation to conveniently complete the corresponding feeding operation;

[0045] Figure 8It is shown that when unloading, the operator can remove the plants on the surface of the movable plate 42 at a convenient operating height according to his or her own height. Before removing the plants, the operator needs to first contact the plug-in constraint relationship between the second shaft rod 44 and the side plate 41, lift the receiving tray to the corresponding height of the movable plate 42, and then manually move the movable plate 42 so that the movable plate 42 tilts toward the front of the incubator 1. Then, under the action of gravity, the plants automatically move out of the surface of the movable plate 42, and then restore the horizontal constraint state of the movable plate 42. Then, the plants on the surface of the upper movable plate 42 or the lower movable plate 42 can be selectively removed.

[0046] Taking the removal of the plants on the upper movable plate 42 as an example, at this time, the pulling rod 5 above the movable plate 42 for the first round of removing the plants needs to be pulled outwards, so that the upper movable plate 42 can fall down. At this time, the winding motor 2 releases part of the winding rope 21, so that the upper movable plate 42 can fall down. Then the first round of removing operation is repeated until all the plants on the surface of the upper movable plate 42 are removed and the upper movable partition units 4 are in the folded state. Then, the winding motor 2 is started to lift the folded movable partition units 4, so that the lower movable plate 42 can be lifted for the corresponding unloading operation.

[0047] After the pull rod 5 is pushed into the insertion rail 11, it can play a horizontal restraining role, so that the supporting role of the movable part 51 remains relatively stable without affecting the sliding in the vertical direction, so that the multiple movable partition units 4 can move in the required space after all the supports are complete.

[0048] The ends of the first and second shafts 43 and 44 are both rotatably connected to the surface of the side plate 41 , and in the initial state, the sum of the lengths of the two second shafts 44 and the compression spring 46 is greater than the length of the first shaft 43 .

[0049] Specifically, due to the length design of the No. 2 shaft 44 and the compression spring 46, when the No. 1 shaft 43 and the No. 2 shaft 44 are both plugged into the side plate 41 in the initial state, the movable plate 42 can maintain a stable horizontal state. When the No. 2 shaft 44 approaches each other and is disengaged from the side plate 41, the movable plate 42 can be easily moved under the action of the No. 1 shaft 43 to switch to a state for convenient loading and unloading.

[0050] The cross section of the movable member 51 in the initial state is V-shaped, and the tip of the cross section of the movable member 51 in the initial state faces the front of the incubator 1 .

[0051] Specifically, the design of the movable part 51 is such that when the pulling rod 5 is pulled outward, the movable part 51 is driven to fold, so that the two movable partition units 4 can be folded and compressed. On the contrary, the two adjacent movable partition units 4 are supported to provide space for the placement of the plants and the subsequent acceptance of the corresponding accelerated vernalization operation.

[0052] The intercepting plate 8 is connected to the rear of the top surface of the uppermost movable plate 42 , and the cross-sectional width of the movable plate 42 is smaller than the cross-sectional width of the interior of the incubator 1 .

[0053] Specifically, the design of the interception plate 8 is similar to the function of the pleated spring sheet 7, which plays a protective interception role. In addition, the difference in cross-section between the movable plate 42 and the inner wall of the incubator 1 allows a gap to be maintained between the inner wall of the incubator 1 and the movable plate 42, thereby facilitating the circulation of air inside the incubator 1.

[0054] It also includes a PLC intelligent control system, which includes a control processor installed on the surface of the sealed door panel. The control processor includes a state monitoring module, an adjustment execution module, and an auxiliary pick-up and delivery module. The state monitoring module is connected to the temperature and humidity sensor, the CO2 sensor, and the light sensor signal to monitor the temperature, humidity, CO2 concentration, and light environment in the incubator 1;

[0055] The adjustment execution module is electrically connected to the winding motor 2, the refrigerator 3, the fill light 6 and the heat-absorbing fan installed on the back of the incubator 1, and is used to control the start and stop of the winding motor 2, the refrigerator 3 and the heat-absorbing fan;

[0056] The auxiliary pick-up and delivery module is connected to the electromagnetic rod 45 via a signal, and is used to switch the restraint connection state between the movable plate 42 and the side plate 41 .

[0057] A supply pipe is installed through the interior of the incubator 1, and the input end of the supply pipe is connected to a CO2 adsorption filter. A pressure reducing valve and a solenoid valve are installed on the surface of the supply pipe, and the input end of the CO2 adsorption filter is connected to an adsorption fan.

[0058] Specifically, the fill light 6 and the light sensor cooperate with each other, the CO2 concentration cooperates with the adsorption fan, the temperature and humidity sensor and the refrigerator 3 and the heat-absorbing fan cooperate with each other, and the temperature, humidity, light and CO2 concentration in the incubator 1 can be comprehensively and intelligently adjusted to meet the needs of low temperature accelerated vernalization in the incubator 1.

[0059] In addition, in accordance with the operational requirements during loading and unloading, the winding of the winding motor 2 and the opening and closing of the electromagnetic rod 45 are controlled to facilitate convenient loading and unloading operations, which can not only reduce the occupation of the effective space in the incubator 1 by mechanical material extraction, but also realize convenient manual operation and reduce manual labor.

[0060] Second implementation method:

[0061] Figure 9-10 It is shown that the surface of the movable plate 42 is provided with multiple equally spaced strip grooves 421, the inner wall of the strip groove 421 is connected to the magnetic plate 424 through an axis rod, the bottom wall of the strip groove 421 is connected to the electromagnetic strip 422 and the return spring 423, and the electromagnetic strip 422 and the magnetic plate 424 attract each other.

[0062] The return spring 423 is located between the electromagnetic strip 422 and the shaft, and in the initial state, the return spring 423 is in a compressed state. The initial elastic force of the return spring 423 is greater than the gravity of the magnetic plate 424 and less than the magnetic attraction force between the electromagnetic strip 422 and the magnetic plate 424.

[0063] Different from the first embodiment, when potted plants are being transported, potted plants placed later on the same movable plate 42 surface may collide with potted plants placed earlier, affecting the safety of the plants.

[0064] Specifically, Figure 11-12 As shown, after a row of potted plants is placed first, the electromagnetic strip 422 in the strip groove 421 is gradually closed along the movable plate 42 from the rear wall to the front of the incubator 1, so that the magnetic plate 424 can rotate under the action of the reset spring 423, forming an inclined structure with the surface of the movable plate 42, thereby achieving a subsequent separation and interception effect, thereby preventing collision accidents between the potted plants placed in the previous and next batches.

[0065] In addition, the electromagnetic strip 422 is only activated during loading and unloading to ensure the flatness of the surface of the movable plate 42 (it is in a gradually closed state during loading). When the movable part 51 is in a folded state, the inclination of the magnetic plate 424 is limited, which will not affect the normal folding of the upper and lower movable plates 42. Therefore, the power demand of the electromagnetic strip 422 is within a controllable range.

[0066] In summary, through the lifting and separation design, the labor of sending plants into the incubator 1 is greatly reduced, the operating efficiency is improved, and the PLC intelligent control system is used to comprehensively and intelligently adjust the temperature, humidity, light and CO2 concentration in the incubator 1 to meet the needs of low-temperature accelerated vernalization in the incubator 1. In addition, for potted plants, when feeding, the electromagnetic strip 422 is gradually closed to make the magnetic plate 424 form an inclined structure to separate the plants, avoid collision, and further protect the safety of the plants.

[0067] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
