Description

Technical Field

[0001] The present invention relates to the technical field of planting ventilation, and in particular to an intelligent ventilation device for agricultural fruit cultivation. Background Art

[0002] In modern agricultural production, advances in fruit cultivation technology are crucial to improving fruit quality and yield. Soil aeration is one of the important factors affecting the healthy growth of fruit tree roots. Good soil aeration conditions can promote root respiration, enhance nutrient absorption capacity, and reduce root diseases caused by hypoxia. Currently, some agricultural facilities have adopted ground ventilation equipment (such as fans or ventilation ducts) to improve air circulation in greenhouses or sheds, but these technologies mainly target gas exchange in the plant canopy and ignore the problem of oxygen supply within the soil.

[0003] The Chinese patent with the authorization announcement number CN222148435U discloses a ventilation device for grape cultivation, which belongs to the field of ventilation devices. It comprises a pre-buried pipe, on which a support column is provided, and on the end of the support column away from the pre-buried pipe, a solid soil block is provided, and an atomizing device is provided, and the atomizing device is provided at the upper end of the solid soil block, and the atomizing device is provided with a water injection port. The utility model solves the problem that when the pre-buried pipe used to increase the oxygen content in the soil in the existing ventilation structure is buried in the soil and starts to work, the fan provided on the pre-buried pipe draws the outside air into the pre-buried pipe, and then discharges it through the holes provided on the pre-buried pipe and fills it into the soil to achieve the purpose of increasing the oxygen content in the soil. However, ventilating the soil for a long time will cause the water in the soil to evaporate, making the soil dry, which may cause the grape vines to lack water and become dry, which is not conducive to the growth of grapes.

[0004] The above device has the following shortcomings: the embedded tube is buried in the soil, and air flow is injected into the embedded tube to cause the film spikes to expand and penetrate into the soil. Although it has a certain effect by reducing the cavity volume to increase the air flow speed, clay soil may still block the air outlet of the film spikes. Moreover, for compacted or clay soil, due to the large resistance, the film material may not be able to effectively penetrate due to insufficient strength, and may even cause the spikes to bend or break. Summary of the Invention

[0005] The purpose of the present invention is to provide an intelligent ventilation device for agricultural fruit cultivation, which can ventilate after drilling into the soil, adapt to various types of soil, avoid affecting ventilation due to blockage of the air outlet, and extend the service life of the ventilation device.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: an intelligent ventilation device for agricultural fruit cultivation, comprising a support frame, connecting plates sliding on both sides of the support frame, and multiple obliquely arranged soil drills fixedly installed on the connecting plates. The multiple soil drills on the connecting plates on both sides are symmetrically arranged, and the soil drill includes a drill barrel, the bottom of the drill barrel is provided with an air outlet and is hinged with multiple opening and closing petals to close the air outlet. A ventilation pipe for ventilating to the air outlet is fixed in the drill barrel, a drive assembly is installed on the support frame, and the drive assembly controls the multiple soil drills to be obliquely inserted into the soil, a bottom plate is fixed at the bottom of the support frame, and two groups of loosening assemblies located on both sides of the support frame are installed at the bottom of the bottom plate.

[0007] By adopting the above technical solution, the support frame is placed between two rows of planted fruit trees, so that the driving component drives multiple augers on both sides to descend and insert them obliquely into the soil, the opening and closing petals open to expose the air outlet, and ventilation is allowed into the soil through the ventilation pipe, which can improve the oxygen supply to the soil and promote the healthy growth of plant roots; the air outlet is buried in the soil by the augers, which can adapt to diverse soils and effectively avoid blockages that may be caused by clay soil. At the same time, due to the certain strength of the structure, the augers can be prevented from bending or breaking due to repeated use of ventilation, thereby extending the service life of the device, and the augers can be removed from the soil at any time, which is conducive to cleaning and repairing the augers or flexible replacement of the ventilation position of the augers.

[0008] The present invention is further configured as follows: a plurality of the opening and closing petals are enclosed in a bullet shape, a sleeve sleeved on the outside of the ventilation pipe slides in the drill barrel, a slide cylinder sliding in the drill barrel is fixed to the upper end of the sleeve, an iron ring is fixed to the bottom end of the slide cylinder, a circle of electromagnets located below the iron ring is fixed to the inner wall of the drill barrel, the bottom end of the sleeve slides and passes through the electromagnet, and a first push rod is hinged between the sleeve and the inner wall of the opening and closing petals, and a first spring sleeved on the outside of the sleeve is fixed between the slide cylinder and the electromagnet.

[0009] By adopting the above technical solution, after the soil drill is obliquely inserted into the soil, the electromagnet is energized, the electromagnet attracts the iron ring, the iron ring drives the slide and the sleeve to press down, the first spring contracts, and when the sleeve is pressed down, the multiple first push rods at the bottom push the multiple opening and closing petals to rotate relative to the drill tube, opening the air outlet, and then the ventilation pipe supplies air to the air outlet to inject the air into the soil; when the opening and closing petals are closed, the air outlet is protected, which can effectively avoid the air outlet from being blocked. At the same time, the opening and closing petals are surrounded by a bullet shape, which is more conducive to the insertion of the soil drill as a whole into the soil, effectively improving the efficiency of pipe burying; when the soil drill needs to be taken out, the electromagnet is de-energized, the slide and the sleeve are moved back upward under the push of the first spring, and then the sleeve pulls the opening and closing petals through the first push rod to close the air outlet, and continues to protect the air outlet again when the soil drill exits the soil.

[0011] By adopting the above technical solution, when ventilation is carried out, the fan is started, and the fan supplies air to the ventilation box through the air supply pipe. Since the upper end of the ventilation pipe is connected with the ventilation box, the air in the ventilation box is poured into multiple ventilation pipes, and then transported through the ventilation pipes and poured into the soil from the air outlet.

When the first drive shaft drives the second bevel gear to rotate through the first bevel gear at the end, and then the second drive shaft rotates, the first rectangular rod is matched with the first rectangular groove. The combination drives the third drive shaft to rotate, and then the third bevel gear at the end of the third drive shaft rotates, and the fourth bevel gear engaged with it rotates, so that the rotating shaft and the rotating drum rotate, driving multiple loosening rods to rotate to loosen the soil, realizing first turning the soil and then injecting air for ventilation. After turning the soil, the porosity of the soil increases, which can make the ventilation gas penetrate evenly, avoid local air blockage, and improve the air permeability of the deep root system; after turning the soil is completed, the first drive shaft no longer rotates, the cam stops pushing the roller, and the second mounting frame, rotating drum and loosening rod retreat to the bottom of the base plate under the pull of the second spring, so as to avoid affecting the downward insertion work of the drill, thereby improving the overall ventilation work smoothness.

When the connecting frame 402 slides down, the connecting rods 404 at the four corners and the second push rod 408 push the limit rod 407 to slide in the limit groove 406, that is, the connecting plates 2 on both sides fixed with the limit rod 407 move synchronously and mirror-imagely along the track of the limit groove 406, that is, when the connecting frame 402 descends When the connecting plate 2 is pushed by the second push rods 408, it first moves downward in the vertical direction. That is, when the soil drill 3 moves downward but has not yet been inserted into the soil, the driving rack 701 fixed to the connecting rod 404 descends and drives the driving gear 702 to rotate, and then the fifth bevel gear 703 coaxially fixed to the driving gear 702 rotates, and then the sixth bevel gear 707 meshing with the fifth bevel gear 703 rotates, and the fifth driving shaft 706 rotates, driving the sixth driving shaft 706 through the second rectangular rod 708 and the second rectangular groove 709. 10 rotates, the seventh bevel gear 711 fixed to the sixth drive shaft 710 rotates, driving the eighth bevel gear 712 to rotate, causing the first drive shaft 604 to rotate. The rotation of the first drive shaft 604 pushes the roller 614 and the second mounting bracket 602 to move away from the first drive shaft 604 through the cam 613. The second guide rod 603 guides, and the first rectangular rod slides in the first rectangular groove, causing the second mounting bracket 602, the rotating drum 609 and the loosening rod 610 to move out from the bottom of the base plate 5, and cooperate with the second spring 61 5. The soil area where the auger 3 is to be inserted is loosened back and forth. When the first drive shaft 604 drives the second bevel gear 608 to rotate through the first bevel gear 607 at the end, the second drive shaft 605 rotates, and the third drive shaft 606 is driven to rotate through the first rectangular rod and the first rectangular groove. Then, the third bevel gear 611 at the end of the third drive shaft 606 rotates, and the fourth bevel gear 612 engaged therewith rotates, causing the rotating shaft and the rotating drum 609 to rotate, driving the multiple loosening rods 610 to rotate to loosen the soil;When the limiting rod 407 slides in the lower arc-shaped limiting groove 406, that is, before the soil drill 3 starts to be obliquely inserted into the soil, the driving rack 701 is no longer engaged with the driving gear 702, that is, the first driving shaft 604 stops rotating, and the second mounting bracket 602, the rotating drum 609 and the loosening rod 610 retreat to the bottom of the base plate 5 under the pull of the second spring 615, and the rotating drum 609 and the loosening rod 610 no longer rotate to avoid affecting the downward insertion work of the soil drill 3. Then, the connecting plate 2 moves obliquely under the drive of the limiting rod 407 and the connecting rod 404, driving multiple soil drills 3 to move obliquely and insert into the soil, When power is supplied to 308, the electromagnet 308 attracts the iron ring 307, which drives the slide 306 and the sleeve 305 downward, causing the first spring 310 to contract. When the sleeve 305 is pressed downward, the multiple first push rods 309 at the bottom push the multiple opening and closing petals 303 to rotate relative to the drill tube 301, opening the air outlet 302 and starting the fan 8. The fan 8 supplies air to the ventilation box 10 through the air supply pipe 9. Since the upper ends of the ventilation pipes 304 are connected to the ventilation box 10, the air in the ventilation box 10 is poured into the multiple ventilation pipes 304, and then transported through the ventilation pipes 304 to the soil through the air outlet 302, thereby ventilating the soil.

[0064] During soil ventilation, the water pump is started to pump out the water in the water tank 15, and the water is transported to the water pipe 13 through the water supply pipe 16, and then flows out from the drip irrigation head 14 for drip irrigation, so as to loosen the soil first, and then ventilate, inject steam and drip irrigation synchronously. After turning the soil, the porosity of the soil increases, and the synchronous drip irrigation and gas injection can make the water infiltrate evenly along the air gap. At the same time, the motor is controlled to drive the control shaft 171 to rotate, and then the control shaft 171 drives the control plate 173 and the water pipe 13 to swing back and forth through the control groove 172 and the control rod 174 to perform drip irrigation.
