Description

Technical Field

[0001] This utility model relates to the field of planting spraying technology, specifically to a device for directional spraying of Trichoderma spore suspension. Background Technology

[0002] Trichoderma is a widely used biocontrol fungus. Its spore suspension (a preparation in which live spores are dispersed in a liquid carrier) has multiple functions in agriculture, horticulture and ecological restoration. Trichoderma inhibits pathogens through "space competition", "nutrient competition", "antibiotic effect" and "parasitic effect", and has significant effects on a variety of plant diseases.

[0003] Trichoderma can rapidly colonize the rhizosphere to combat root rot, wilt, and damping-off caused by Fusarium, Phytophthora, and Rhizoctonia solani. It seizes the living space and nutrients of pathogens and secretes chitinase and β-1,3-glucanase to degrade the cell walls of pathogens, inhibiting their growth. In soils with continuous cropping obstacles or contaminated soils, Trichoderma inhibits pathogen accumulation through competitive colonization, improving the soil microecological balance. Simultaneously, it secretes organic acids (such as citric acid and oxalic acid) to regulate soil pH and promote the proliferation of beneficial microorganisms (such as nitrogen-fixing bacteria and phosphate-solubilizing bacteria), gradually restoring soil health.

[0004] Therefore, we propose a directional spraying device for Trichoderma spore suspension to ensure its application effect through directional spraying. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This device is applied to the directional spraying of Trichoderma spore suspension. A pressure pump pressurizes the storage tank through a pump pipeline, increasing the internal air pressure and forcing the Trichoderma spore suspension to flow towards the drain pipe. The drain pipe is controlled by a one-way valve to ensure that the Trichoderma spore suspension can only flow out in one direction, preventing backflow. When the one-way valve is opened, the pressure applied by the pressure pump causes the Trichoderma spore suspension to be sprayed outwards and transported through a flexible metal hose connected to one end of the drain pipe. The flexible metal hose allows for free movement. Adjusting the spray angle adapts to different spraying locations. One end of the metal hose is connected to an extended handheld tube, extending the spraying distance and allowing operators to precisely control the spraying position. This is especially suitable for narrow spaces, facilitating deeper spraying. Furthermore, a spray head is installed at the end of the metal hose to achieve atomized spraying, resulting in more uniform spraying and improved spray uniformity. This ensures that spores adhere evenly to the target surface, ensuring precise control of the spraying direction during the Trichoderma spore suspension spraying process, concentrating the action on the target area, such as plant roots or diseased parts, thereby improving utilization.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a directional spraying device for Trichoderma spore suspension, including a base plate 1, a storage tank 2 fixedly connected to one side of the upper surface of the base plate 1, the inner cavity of the storage tank 2 being filled with Trichoderma spore suspension, a top cover 3 installed on the upper surface of the storage tank 2, and the two being threadedly connected, a drain pipe 7 fixedly connected to the side wall of the storage tank 2 near the bottom, and the drain pipe 7 communicating with the inner cavity of the storage tank 2, a one-way valve 8 installed on the side wall of the drain pipe 7, a flange provided at the end of the drain pipe 7 away from the storage tank 2, a metal hose 9 flanged to the flange of the drain pipe 7, a handheld pipe 10 fixedly connected to the other end of the metal hose 9, and the handheld pipe 10 being extended in length, a spray head provided at the other end of the handheld pipe 10, a pressure pump 5 fixedly connected to the other side of the upper surface of the base plate 1, a pressure pump pipe 6 symmetrically connected to the output and input ends of the pressure pump 5, and the other end of the pressure pump pipe 6 communicating with the storage tank 2.

[0017] A liquid storage tank 2 is provided on the surface of the base plate 1. The inner cavity of the liquid storage tank 2 is filled with Trichoderma spore suspension. The top is sealed by screwing the top cover 3 onto the liquid storage tank 2. A pressure pump 5 is provided on one side of the liquid storage tank 2. The pressure pump 5 pressurizes the liquid storage tank 2 through the pressure pump pipe 6. A drain pipe 7 is provided at the bottom of the liquid storage tank 2. The drain pipe 7 drains water outward through a one-way valve 8. When the one-way valve 8 is opened, the pressure applied by the pressure pump 5 will cause the Trichoderma spore suspension to spray outward. It is delivered through a metal hose 9 connected to one end of the drain pipe 7. One end of the metal hose 9 is connected to an extended handheld tube 10 for easy access to the spraying position. A spray head is provided at the end of the metal hose 9 to achieve atomized spraying, so as to achieve more uniform spraying and ensure the spraying process of Trichoderma spore suspension.

[0018] like Figure 1 As shown, a manual structure 4 is provided on one side of the upper surface of the liquid storage tank 2. The bottom of the manual structure 4 is located in the inner cavity of the liquid storage tank 2 and does not come into contact with the Trichoderma spore suspension in the inner cavity of the liquid storage tank 2.

[0019] During spraying operations, if there is no stable power supply at the work site or the existing power lines cannot effectively connect to the equipment due to distance, layout, damage, or other reasons, in order to ensure the continuity and efficiency of the spraying work, the manual structure 4 can be flexibly used to supplement the pressure. The manual structure 4 converts human power into mechanical energy through mechanical transmission, drives the liquid storage tank 2 to generate a preset pressure, thereby replacing the pressure supply function of the electric pump.

[0020] like Figure 1 , Figure 2 , Figure 3 The manual structure 4 shown includes a cylinder 41. The bottom of the cylinder 41 is fixedly connected to one side of the upper surface of the liquid storage tank 2. An air inlet / outlet block 42 is fixedly connected to the bottom of the cylinder 41 and is located in the inner cavity of the liquid storage tank 2. The inner cavity of the air inlet / outlet block 42 is provided with a polyhedral groove. A sphere 43 is provided in the inner cavity of the air inlet / outlet block 42. An air hole is provided in the annular shape at the bottom of the inner cavity of the air inlet / outlet block 42. A tension rod 44 is sleeved in the inner cavity of the cylinder 41. A handle 45 is fixedly connected to the top of the tension rod 44. A tension block 46 is fixedly connected to the bottom of the tension rod 44. A rubber ring 47 is provided on the outer ring wall of the tension block 46. The outer ring wall of the rubber ring 47 is in contact with the inner wall of the cylinder 41.

[0021] The principle of the manual structure 4 described above is explained in detail. The manual structure 4 realizes the reciprocating motion of the pull rod 44 in the inner cavity of the cylinder 41 by pressing down or pulling up the handle 45. The pull block 44 at the bottom of the pull rod 44 moves up and down in the cylinder 41. Combined with the directional opening and closing of the bottom air intake and exhaust block 42 and the ball 43, air compression is completed in two stages. When the handle 45 is pressed down, the pull block 44 moves down with the pull rod 44. At the same time, the rubber ring 47 on the side wall of the pull block 44 fits against the inner wall of the cylinder 41, which increases the space in the upper part of the cylinder 41 and reduces the internal air pressure. A negative pressure is formed. The sphere 43 located at the bottom of the air intake and exhaust block 42 is pushed open by atmospheric pressure and fits against the bottom of the air intake and exhaust block 42 because the air pressure inside the cylinder 41 is lower than the external atmospheric pressure. External air enters the liquid storage tank 2 through the annular air hole at the bottom of the air intake and exhaust block 42. When pulled upward, the principle is the opposite of the above. The space at the top of the cylinder 41 decreases, the internal air is compressed, and the air pressure increases. The sphere 43 closes under the action of the internal air pressure and latches with the top opening of the air intake and exhaust block 42, preventing air from flowing back to the outside. The above operation realizes the manual overall pressurization process.

[0022] like Figure 1 As shown, it also includes four bottom wheels 11, which are arranged symmetrically at the four corners. The upper surfaces of the four bottom wheels 11 are fixedly connected to the lower surface of the base plate 1 at the four corners. The side walls of the base plate 1 are symmetrically fixedly connected with pin seats 12. The inner cavity of the pin seat 12 is rotatably connected with a pin 13. The outer wall of the pin 13 is hinged with a strip plate 14. A push rod 15 is fixedly connected between the top inner side walls of the two strip plates 14.

[0023] To further improve the ease of operation and site adaptability of spraying, a fixed bottom wheel 11 is added to the bottom of the base plate 1. This design can easily cope with complex terrains such as farmland furrows, orchard spacing, and greenhouse passageways. Operators can push or assist in traction through the push rod 15 and the strip plate 14. At the same time, the strip plate 14 and the pin seat 12 are hinged through the pin 13, which can realize the change of some angles and greatly improve the pushing efficiency.

[0024] like Figure 1 , Figure 5 As shown, a sleeve 16 is fixedly connected to the upper surface of the base plate 1 near the pin seat 12, and there is a gap between the two. The inner cavity of the sleeve 16 is fitted with a plug rod 17, and the bottom end of the plug rod 17 is arc-shaped.

[0025] When it is necessary to limit the movement of the base plate 1, the base plate 1 can be limited by inserting the rod 17 into the inner cavity of the sleeve 16, with the bottom of the rod 17 inserted into the ground soil.

[0026] like Figure 1 As shown, a strip window 18 is provided on the side wall of the liquid storage tank 2. The strip window 18 is located at the top of the drain pipe 7. The strip window 18 is long and vertical.

[0027] The use of the strip window 18 allows for constant monitoring of the liquid level inside the storage tank 2, and the addition of Trichoderma spore suspension can be made according to the liquid level to ensure subsequent spraying work.

[0028] like Figure 1 As shown, a sleeve block 19 is fixedly connected to the side wall of the liquid storage tank 2 near the top, and a circular through hole is provided at the center of the sleeve block 19.

[0029] With the sleeve 19 in place, when the insertion rod 17 is not needed for positioning, it can be inserted into the inner cavity of the sleeve 19 for storage.

[0030] Working Principle: This device is used for the directional spraying of Trichoderma spore suspension. A pressure pump 5 is installed on one side of the storage tank 2. The pressure pump 5 pressurizes the storage tank 2 through the pressure pump pipe 6. A drain pipe 7 is installed at the bottom of the storage tank 2. The drain pipe 7 drains water outward through a one-way valve 8. When the one-way valve 8 is opened, the pressure applied by the pressure pump 5 causes the Trichoderma spore suspension to be sprayed outward. It is transported through a metal hose 9 connected to one end of the drain pipe 7. One end of the metal hose 9 is connected to an extended handheld tube 10 for easy access to the spraying position. A spray head is installed at the end of the metal hose 9 to achieve atomized spraying, so as to achieve more uniform spraying and ensure the spraying process of Trichoderma spore suspension.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
