Description

Technical Field

[0001] The present invention relates to the technical field related to forage grass planting, and in particular to a cultivation device for forage grass planting and a use method thereof. Background Art

[0002] Forage generally refers to grass or other herbaceous plants used by livestock. Forage has strong regeneration ability and can be harvested many times a year. It is rich in various trace elements and vitamins, so it has become the first choice for raising livestock. The quality of forage varieties directly affects the economic benefits of animal husbandry and needs to be paid attention to. Forage is the basis for the development of livestock and poultry production, especially the production of herbivorous livestock. Forage contains not only various nutrients necessary for livestock, but also crude fiber, which is particularly important for maintaining the health of ruminant livestock, which cannot be replaced by grain and other feeds. High-quality forage can fully meet the nutritional needs of general livestock, and how to cultivate forage has become a top priority.

[0003] After searching the patent number CN114451288A, the patent includes a bottom frame, an immersion cultivation mechanism, a detachable plate, a detachable frame, a limiting mechanism and a driving mechanism. The immersion cultivation mechanism is evenly installed inside the bottom frame, the detachable plate is detachably installed on the upper end of the bottom frame, the bottom frame and the detachable frame are detachably connected, the limiting mechanism is evenly installed inside the detachable frame, and the rear end of the detachable frame is installed with a driving mechanism. Compared with the prior art, the patent number CN114451288A includes a bottom frame, an immersion cultivation mechanism, a detachable plate, a detachable frame, a limiting mechanism and a driving mechanism. The immersion cultivation mechanism is evenly installed inside the bottom frame, the detachable plate is detachably installed on the upper end of the bottom frame, the bottom frame and the detachable frame are detachably connected, the limiting mechanism is evenly installed inside the detachable frame, and the rear end of the detachable frame is installed with a driving mechanism. The problem that the forage is placed in the existing cultivation device is that the forage is relatively dense and easily affects each other's development. During manual separation, the forage is easily damaged by the manipulation of the hands of the personnel between the forage. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that most of the forage grass cultivated with nutrient solution in the above-mentioned technology is planted indoors, so the heating of the forage grass may affect the temperature increase of the nutrient solution, and the temperature change will directly affect the solubility of various nutrients in the nutrient solution, such as potassium nitrate and potassium dihydrogen phosphate. As the temperature increases, the solubility will further increase; but for calcium nitrate and calcium chloride, after the temperature rises to a certain level, their solubility may decrease, and precipitation is likely to occur. Once precipitation occurs, the calcium content in the nutrient solution will decrease, destroying the original reasonable nutrient ratio and affecting the absorption and utilization of calcium by the forage grass. Therefore, a cultivation device for forage grass planting and a method of use thereof are proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A cultivation device for forage planting, comprising a cultivation and planting support frame, characterized in that a square groove is arranged above the cultivation and planting support frame, a fixed block is fixedly installed inside the square groove, a support block is fixedly connected above the fixed block, the support block is rotatably connected to an output gear, the output gear is meshed with a sliding rack, a side of the sliding rack away from the output gear is fixedly connected to a liquid storage tank, a rotating plate is rotatably connected inside the liquid storage tank, a clamping block is fixedly connected above the rotating plate, a tension spring is fixedly connected to the bottom of the rotating plate, the other end of the tension spring is fixedly connected to the sliding rack, the sliding rack is slidably connected to a vertical plate, and a pointed block is fixedly installed above the square groove.

[0008] The above technical solution further includes:

[0009] The cooling mechanism comprises a cold gas generator arranged on the side of the cultivation and planting support frame, one end of the cold gas generator is fixedly connected to a hose, and the other end of the hose is fixedly connected to the opening of the cooling pipe rack.

[0010] A liquid distribution box is arranged at the bottom of the cultivation and planting support frame, the outlet of the liquid distribution box is fixedly connected to the pump body, a suction box is arranged outside the pump body, a cover plate is arranged above the suction box to prevent foreign objects from falling into it, the pump body is used to supply nutrient solution to the spray head, and the spray head is fixed above the cultivation and planting support frame.

[0011] A cross brace slot rod is fixedly connected to one side of the cultivation and planting support frame close to the cold gas generator, a square groove is opened on the surface of the cross brace slot rod, the sliding rack passes through the square groove and is fixedly connected to the cooling pipe rack, and the sliding rack is slidably connected to the cross brace slot rod.

[0012] The two parts of the cultivation and planting support frame are provided with sliding grooves for placing the filtering sliding plate, and the surface of the filtering sliding plate is provided with a filtering net for filtering the roots and leaves of forage grass. By providing the filtering net, regular cleaning can be carried out to prevent clogging.

[0013] A liquid storage cavity for storing nutrient solution is provided on one side of the cultivation and planting support frame close to the bottom of the filtering sliding plate, the opening of the liquid storage cavity is provided with a liquid storage door, and a pipeline for releasing nutrient solution is provided on the surface of the liquid storage door.

[0014] The liquid storage tank is provided with a bottom edge inside, and the bottom edge inside the liquid storage tank is used to resist the pulling force on the tension spring. By setting the pulling force of the tension spring, the nutrient solution inside the liquid storage tank can be tightly blocked inside to prevent it from flowing out.

[0015] The surface of the cultivation and planting support frame is provided with a plurality of groups of leakage holes for the nutrient solution to enter the liquid storage cavity, and the nutrient solution can be stored by providing the leakage holes.

[0016] The cooling pipe rack is slidably connected with the leakage hole through the guide hole.

[0017] A flatness detection method for road and bridge engineering construction, the specific steps are:

[0018] S1: After the output gear is started, as the core power source, it meshes with the sliding rack. Based on the transmission principle of the gear rack, the rotational motion of the output gear is converted into the linear downward motion of the sliding rack. At the same time, the first bevel gear on the side of the output gear is tightly meshed with the second bevel gear. After the second bevel gear receives the power from the first bevel gear, it drives the stirring plate fixedly connected to it to rotate around the axis;

[0019] S2: While the output gear is transmitting, the fourth bevel gear fixed to one end of the connecting rod rotates with the linkage of the connecting rod, and the fourth bevel gear meshes with the third bevel gear, driving the push gear to rotate, and the push gear meshes with the sliding rack, and finally the sliding rack drives the cooling pipe rack to slide along the guide hole on the surface of the grass fence;

[0020] S3: The cooling pipe rack delivers low-temperature gas to the grass sandwiched between the multiple groups of grass fences, and the cooling pipe rack emits the gas through the small holes on its surface;

[0021] S4: On the other hand, as the sliding rack descends, the rotating plate on its side gradually approaches the sharp block on the surface of the square groove. When the two come into contact, the sharp block applies a squeezing force to the rotating plate, and the rotating plate rotates around the axis to overcome the tension of the tension spring, so that the block is lifted, and the bottom opening of the liquid storage tank is opened. The nutrient solution stored inside begins to flow into the square groove under the action of gravity, and at the same time as the cooling pipe rack completes the cooling gas delivery to the forage, the nutrient solution in the liquid storage tank just flows completely into the square groove;

[0022] S5: After all the nutrient solution flows into the square tank, the output gear rotates in the opposite direction, driving the stirring plate to rotate in the opposite direction, so as to fully stir and mix the newly-flown nutrient solution in the square tank;

[0023] S6: The stirring process continues until the cooling tube rack is completely pulled out of the guide holes of the multiple groups of grass fences. At this time, the nutrient solution is stirred evenly, and the preliminary preparation work is completed. Then, the nutrient solution release sensor is based on the pre-set program and real-time monitoring of grass growth conditions, environmental temperature and humidity, soil moisture and other parameters;

[0024] S7: When it is determined that the grass needs to be irrigated with nutrient solution, the nutrient solution release sensor sends a command to control the interception plate and the square groove to slide, and adjust the height of the interception plate, so that the nutrient solution originally blocked by the interception plate inside the square groove is released to the roots of the grass between the multiple groups of grass guardrails through the leakage holes and other channels.

[0025] The present invention has the following beneficial effects:

[0026] 1. In the present invention, by arranging a cold gas maker on one side of the cultivation device, it is possible to accurately manufacture and transport low-temperature gas to the cooling tube rack according to the real-time temperature of the grass growth environment and the temperature feedback of the nutrient solution. The cooling tube rack, with its surface holes, evenly disperses the low-temperature gas between the grass plants, effectively reducing the heat accumulation generated by the respiration of the grass, etc., and avoiding abnormal increase in the temperature of the nutrient solution. In this way, for temperature-sensitive nutrients such as calcium nitrate and calcium chloride, the temperature of the environment in which they are located can be maintained stable, preventing the solubility reduction and precipitation caused by high temperature, ensuring the sufficient supply of key nutrients such as calcium in the nutrient solution, ensuring the rationality of the nutrient ratio, providing stable and balanced nutritional support for the growth of grass, promoting its healthy development, and improving the quality and yield of grass.

[0027] 2. In the present invention, the transmission stirring system composed of the output gear, the first bevel gear, the second bevel gear and the stirring plate plays a key role in the circulation process of the nutrient solution. When the nutrient solution enters the corresponding area, the gear linkage causes the stirring plate to rotate, fully stirring the inflowing nutrient solution to ensure that various nutrients are evenly dispersed, avoiding local nutrient deficiency or excess due to precipitation and stratification. Whether it is a newly injected nutrient solution or a nutrient solution whose composition may change due to temperature fluctuations, the stirring operation can restore it to a uniform state, allowing the roots of the forage grass to evenly absorb multiple nutrients such as nitrogen, phosphorus, potassium, and calcium everywhere, improving nutrient utilization efficiency, helping the forage grass to thrive, and reducing poor growth caused by uneven nutrients.

[0039] A first bevel gear 6 is provided on the side of the output gear 5 away from the support block 4, and the first bevel gear 6 is meshedly connected with the second bevel gear 7. A connecting rod 39 is fixedly connected below the second bevel gear 7, and a stirring plate 38 is sleeved on the outside of the connecting rod 39. The connecting rod 39 is rotatably connected to the cultivation and planting support frame 1. A fourth bevel gear 29 is fixedly connected to the side of the connecting rod 8 away from the first bevel gear 6, and the fourth bevel gear 29 is meshed with the third bevel gear 27. A push gear 28 is fixedly connected below the third bevel gear 27, and the push gear 28 is meshedly connected with a sliding rack 30. A cooling pipe rack 23 is fixedly connected to the side of the sliding rack 30 away from the push gear 28. A cooling mechanism for reducing the local temperature of forage is provided on the side of the cooling pipe rack 23. A forage guardrail 20 is provided above the cultivation and planting support frame 1, and a guide hole 21 is opened on the surface of the forage guardrail 20. An interception plate 36 is slidably connected above the square groove 3, and a nutrient solution release sensor 37 is fixed on the side of the square groove 3.

[0040] The working principle of a cultivation device for pasture planting and a method of using the same proposed by the present invention is that the rotation of the output gear 5 causes the sliding rack 10 to descend, the first bevel gear 6 on the side of the output gear 5 is meshed with the second bevel gear 7, and the second bevel gear 7 drives the stirring plate 38 to rotate. At the same time, the fourth bevel gear 29 fixed on the side of the connecting rod 8 away from the first bevel gear 6 rotates, and the fourth bevel gear 29 is meshed with the third bevel gear 27 to drive the push gear 28 to rotate, and the push gear 28 is meshed with the sliding rack 30, and then the sliding rack 30 drives the cooling pipe rack 23 to slide, and then the cooling pipe rack 23 passes through the guide hole 21 set on the surface of the pasture guardrail 20, when the rotating plate 12 on the side of the sliding rack 10 contacts the sharp block 15 on the surface of the square groove 3, the sharp block 15 squeezes the rotating plate 12 at the bottom of the liquid storage tank 11, and then the block 13 is lifted while the tension spring 14 is in a stretched state.

[0041] At this time, the nutrient solution in the liquid storage tank 11 can flow into the interior of the square trough 3, and the cooling pipe rack 23 just passes through the multiple groups of grass guardrails 20 above the cultivation and planting support frame 1. The grass sandwiched between the multiple groups of grass guardrails 20 is transmitted with low-temperature gas by the cooling pipe rack 23 to prevent the respiration of the grass from generating a large amount of heat that damages the components inside the nutrient solution. Then, after the cooling pipe rack 23 passes through the multiple groups of grass guardrails 20 and provides low-temperature gas, the nutrient solution in the rotating plate 12 completely flows into the interior of the square trough 3. At this time, the output gear 5 rotates in the opposite direction, and the stirring plate 38 inside the square trough 3 just stirs the nutrient solution. The nutrient solution is stirred and mixed until the cooling pipe rack 23 is completely pulled out of the guide holes 21 of the multiple groups of grass guardrails 20. At this time, the stirring is completed, and then the nutrient solution release sensor 37 will control the interception plate 36 and the square groove 3 to slide according to the needs of the grass, so that the nutrient solution originally blocked by the interception plate 36 inside the square groove 3 is released to the grass between the multiple groups of grass guardrails 20. At this time, due to the low temperature between the grasses, there will be no problem of affecting the solubility of the nutrient solution, so that the solubility will not change, and the calcium element will not be lost in large quantities, which will affect the ratio of the nutrient solution.

Then, the nutrient solution release sensor (37) is based on the pre-set program and the real-time monitoring of the grass growth status, environmental temperature and humidity, soil moisture and other parameters; S7: When it is determined that the grass needs to be irrigated with nutrient solution, the nutrient solution release sensor (37) issues a command to control the interception plate (36) and the square groove (3) to slide, and adjust the height of the interception plate (36) so that the nutrient solution originally blocked by the interception plate (36) inside the square groove (3) is released to the grass roots between the multiple groups of grass guardrails (20) through the leakage holes (22) and other channels.
