Description

Technical Field

[0001] The utility model relates to the technical field of tobacco production and planting, and more specifically to a pest spraying device used for tobacco underground. Background Art

[0002] In the tobacco planting industry, underground pest control is one of the key links to ensure the healthy growth of tobacco plants. Although traditional chemical pesticide treatment methods can effectively control pests, long-term excessive use will lead to increased pesticide residues on tobacco leaves, pests developing resistance, and damage the ecological environment and tobacco quality. Therefore, modern tobacco underground pest application equipment is designed to directly release granular pesticides into the soil pit, aiming to enhance the control effect of underground pests and reduce environmental pollution.

[0003] However, when the prior art pesticide application equipment is inserted into the earth pit for operation, the drug outlet is easily blocked by the soil, which affects the normal discharge of the drug, and further affects the uniformity of drug distribution and the control effect. This not only increases the difficulty of operation and reduces work efficiency, but also may lead to waste of drugs and increase labor costs.

[0004] Therefore, in view of the above-mentioned technical defects, it is necessary to propose a pest spraying device for tobacco underground. Utility Model Content

[0005] The utility model aims to propose a pest spraying device for tobacco underground. When the granular pesticide is thrown into the earth pit, the device can effectively prevent the pesticide outlet from being blocked by soil, thereby ensuring the smooth discharge of the granular pesticide. Through this improved design, the pesticide application efficiency can be improved, ensuring that the pesticide can accurately and effectively act on the target pests, thereby improving the yield and quality of tobacco.

[0006] The utility model provides a pest spraying device for tobacco underground, comprising:

[0007] A bracket, wherein at least three storage barrels are distributed along the top end surface of the bracket, and the storage barrels are filled with a sufficient amount of granular medicine. A feeding pipe is vertically and connected between the inner bottom end surface of the storage barrel and the inner end surface of the bracket;

[0008] A plug assembly, wherein the plug assembly is slidably arranged on the outer wall of the feed tube, wherein the plug assembly comprises a first plug and a second plug, wherein the second plug is slidably arranged on the inner end surface of the first plug, and a material storage groove is provided on the outer wall surface of the second plug;

[0009] A lifting component is arranged on the back of the bracket and is used to drive the cannula component to move up and down.

[0010] Preferably: the first insert tube has a first chamber and a second chamber respectively formed at the inner upper end and the inner lower end, the first chamber and the second chamber are separated from each other, the first chamber is connected to the top end surface of the first insert tube, and the second chamber is connected to the bottom end surface of the first insert tube, and the first insert tube is slidably connected to the outer wall surface of the discharge tube through the first chamber.

[0011] Preferably: the bottom end surface of the inner wall of the first chamber has a raised conical structure, and the side end of the first chamber is provided with a feed discharge channel opposite to the conical structure, at least two feed discharge channels are provided, and the lower end of the feed discharge channel passes through the inner wall surface of the second chamber, and the lower end of the feed discharge channel is arranged in an oblique manner.

[0012] Preferably, the second insert tube is slidably connected to the inner lower end of the second chamber, a spring is provided at the inner upper end of the second chamber, one end of the spring is fixedly connected to the top end surface of the inner wall of the second chamber, and the other end is connected to the second insert tube.

[0013] Preferably, the inner diameter of the second chamber is adapted to the outer diameter of the second cannula.

[0014] Preferably, when the second insert tube is in the extended state, the inner upper end of the material storage tank is staggered with the outlet end of the material discharge channel, and the inner lower end of the material storage tank is exposed to the outside;

[0015] When the second insert tube is retracted, the inner upper end of the material storage trough is aligned with the outlet end of the material discharge channel, and the inner lower end of the material storage trough is retracted into the second chamber and isolated from the external environment.

[0018] The beneficial effects of the utility model are:

[0019] 1. Compared with the prior art, this solution optimizes the drug application process by using the first and second cannulas in coordination. Specifically, the two cannulas are driven by a cylinder and are first inserted into the soil synchronously. During the insertion process, the thrust of the soil causes the second cannulas to enter the interior of the first cannulas, and the drug discharge port is arranged on the second cannulas, so it remains isolated from the soil during the hole opening operation. Subsequently, when the cylinder acts on the first cannulas to move it upward, the second cannulas is reset and moves outward. This action opens the drug discharge port, ensuring that the granular medicine in the drug discharge port can be accurately injected into the soil opening. This improvement effectively avoids the problem of blockage of the drug discharge port and improves the accuracy and efficiency of drug application.

[0020] 2. This solution achieves accurate guidance of the granular medicine by designing the first chamber and the feeding channel on the first cannula. Specifically, after the granular medicine enters the first chamber, it is accurately transported to the storage tank through the feeding channel. This design ensures that all the granular medicine can accurately enter the storage tank, thereby improving the accuracy and efficiency of drug application. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0027] As attached Figure 1 To Attachment Figure 4As shown: a pest spraying device for tobacco underground, including a bracket 1 and a joint 11, the joint 11 is arranged on the back of the bracket 1, and a bolt hole is opened on the joint 11, the bolt hole is used to connect the joint 11 with external farming machinery, including but not limited to tractors or carts. During the specific installation, the bracket 1 and the joint 11 can be connected and fixed to the tail end of the farming machinery through bolts and bolt holes. At least three storage barrels 2 are distributed along the top end surface of the bracket 1, and the storage barrels 2 are filled with a sufficient amount of granular medicine. A discharge pipe 21 is vertically and connected between the inner bottom end surface of the storage barrel 2 and the inner end surface of the bracket 1, and the discharge pipe 21 is used to continuously discharge the granular medicine in the storage barrel 2. A first inserting tube 3 is provided on the outer wall of the feeding tube 21, and a first chamber 31 and a second chamber 32 are respectively provided on the inner upper end and the inner lower end of the first inserting tube 3, wherein the first chamber 31 and the second chamber 32 are separated from each other, and the first chamber 31 is connected with the top end face of the first inserting tube 3, and the second chamber 32 is connected with the bottom end face of the first inserting tube 3, and the first inserting tube 3 is slidably connected with the outer wall of the feeding tube 21 through the first chamber 31. In this way, when in use, the first inserting tube 3 can make the outer wall of the feeding tube 21 move up and down, and the granular medicine in the feeding tube 21 can enter the first inserting tube 3 during the movement.

[0028] Furthermore, the bottom end surface of the inner wall of the first chamber 31 has a convex conical structure, and a feeding channel 33 opposite to the conical structure is opened at the side end of the first chamber 31, and at least two feeding channels 33 are provided, and the lower ends of the feeding channels 33 penetrate the inner wall surface of the second chamber 32. In this way, when in use, the granular medicine can be transferred from the first chamber 31 to the second chamber 32 through the feeding channel 33. The convex conical structure helps to guide the granular medicine from the bottom surface of the first chamber 31 into the feeding channel 33.

[0029] Furthermore, the lower end of the feeding channel 33 is arranged in an oblique manner, so that when in use, the granular medicine can be quickly discharged from the feeding channel 33 through the inclined channel.

[0030] like Figure 1 and Figure 2As shown, a cylinder 4 is vertically arranged on the back of the bracket 1 through a mounting block, and the telescopic rod of the cylinder 4 faces downward, and a connecting plate 41 is fixedly arranged at the telescopic rod of the cylinder 4. The front and rear sides of the bracket 1 are vertically provided with slots 12 opposite to the first plug 3, and the connecting plate 41 is opposite to the slot 12, and then a connecting rod 42 is fixedly arranged in the horizontal direction at one end of the connecting plate 41 facing the slot 12, and one end of the connecting rod 42 is fixedly connected to the outer end surface of the first plug 3, so that when in use, the user can start the cylinder 4 to run, and during operation, the cylinder 4 can control whether the first plug 3 is inserted into the soil on the ground. That is, when the cylinder 4 moves downward, the first plug 3 is normally inserted into the soil, which helps to sprinkle the granular medicine into the soil, and after sprinkling, the cylinder 4 can drive the first plug 3 to move upward and away from the pit on the ground.

[0031] like Figures 1 to 3 As shown, a spring 34 and a second inserting tube 35 are arranged at the upper and lower ends of the second chamber 32. When installed, one end of the spring 34 is fixedly connected to the top surface of the inner wall of the second chamber 32, and the other end is connected to the second inserting tube 35. The second inserting tube 35 is slidably connected to the lower end of the second chamber 32, and the lower end of the second inserting tube 35 also extends to the lower part of the outside of the first inserting tube 3. In this way, in the initial state (i.e., the second inserting tube 35 has not been inserted into the soil on the ground), the spring 34 can push the second inserting tube 35 downward, so that the second inserting tube 35 can protrude from the lower part of the first inserting tube 3. Similarly, when in the contracted state (i.e., the first inserting tube 3 drives the second inserting tube 35 downward to be inserted into the soil on the ground), the soil on the ground can push the second inserting tube 35 into the first inserting tube 3, which is equivalent to the second inserting tube 35 being retracted into the first inserting tube 3.

[0032] Furthermore, the inner diameter of the second chamber 32 is adapted to the outer diameter of the second cannula 35, and this design helps to reduce the gap between the second cannula 35 and the second chamber 32. In this way, when the second cannula 35 slides stably in the second chamber 32, the fluidity of the granular medicine can be prevented from being affected by the excessive gap.

[0033] Furthermore, a storage trough 36 is vertically opened on the outer wall of the second insert tube 35, and the storage trough 36 is arranged opposite to the outlet end of the feeding channel 33, so that when in use, the granular medicine in the feeding channel 33 can accurately fall into the storage trough 36 and be temporarily stored.

[0034] Furthermore, when the second insert tube 35 is in the extended state, the upper end of the storage tank 36 is offset from the outlet end of the material discharge channel 33, and the lower end of the storage tank 36 is exposed to the outside. When the second insert tube 35 is retracted, the upper end of the storage tank 36 is aligned with the outlet end of the material discharge channel 33, and the lower end of the storage tank 36 is retracted into the second chamber 32 and isolated from the external environment.

[0035] During use, when the first insert tube 3 drives the second insert tube 35 to be inserted into the soil, the second insert tube 35 will drive the storage tank 36 to be completely retracted into the second chamber 32. At this time, the granular medicine enters the storage tank 36 through the feeding channel 33 for temporary storage. Since the storage tank 36 is separated from the outside, when the first insert tube 3 is drilling a hole, the soil will not contact the storage tank 36, and the discharge port will not be blocked by the soil. When the first insert tube 3 continues to act to move the second insert tube 35 upward, the resistance of the spring 34 will cause the second insert tube 35 to stretch, and the lower end of the inner part of the storage tank 36 will be exposed to the outside. This design allows the granular medicine to fall smoothly from the storage tank 36 into the earth pit, and the application is successfully completed, while avoiding the problem of the storage tank 36 being blocked by soil and affecting the application efficiency.

[0036] Furthermore, the bottom end surface of the second inserting tube 35 is a plane or conical structure, and the bottom surface of the first inserting tube 3 is a conical structure. By setting the plane structure, it is convenient to contact with relatively soft soil. When in contact, the relatively soft soil helps to push the second inserting tube 35 into the first inserting tube 3. At the same time, the design of the conical structure makes it convenient to break the soil and dig a pit in hard soil.

[0037] Furthermore, the bottom end surface of the inner wall of the storage tank 36 is designed to have a slope structure, and the slope structure facilitates the discharge of the granular medicine in the storage tank 36.

[0038] Furthermore, the internal volumes of the discharge pipe 21, the first chamber 31, the discharge channel 33 and the storage tank 36 are all larger than the volume of a single granular medicine. This design can reduce the risk of getting stuck when discharging the granular medicine.

[0039] The following is the specific workflow of this utility model:

[0040] First, the device is installed at the rear of the agricultural machinery through the joint 11, and then a sufficient amount of granular medicine is introduced into the storage barrel 2 for temporary storage. At this time, the granular medicine enters the first insertion tube 3 and the discharge channel 33 respectively through the discharge pipe 21 under the action of gravity.

[0041] When it is necessary to apply pesticides underground, the device is first moved to the planting site, and then the cylinder 4 is started to drive the connecting plate 41 to move downward, so that the first insert tube 3 and the second insert tube 35 can be inserted into the soil. During the insertion process, the soil can push the second insert tube 35 into the first insert tube 3, so that the material guide groove in the first insert tube 3 can be opposite to the feed channel 33, and the granular medicine can enter the material guide groove for temporary storage. Since the second insert tube 35 is still retracted in the first insert tube 3 at this time, the second chamber 32 in the first insert tube 3 can block the granular medicine in the material guide groove, thereby ensuring that the granular medicine in the storage groove 36 can be stably placed.

[0042] Finally, when the first insert tube 3 is inserted to a predetermined depth in the earth pit, the cylinder 4 is started to drive the first insert tube 3 and the second insert tube 35 to move upward. At this time, the second insert tube 35 lacks the obstruction of soil, and the spring 34 can push the second insert tube 35 to move downward. After the first insert tube 3 continues to move upward, the second insert tube 35 can be fully unfolded, so that the granular medicine in the storage tank 36 can be exposed to the outside, and the granular medicine will automatically fall into the hole, so that the medicine can be dispensed. And because the first insert tube 3 needs to be opened before the medicine is dispensed, and the medicine outlet port of the second insert tube 35 is separated when the hole is opened, this avoids the situation where the soil will contact the medicine outlet port, and thus avoids the problem of soil blockage.

[0043] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application rather than to limit them. The protection scope of the present application is not limited thereto.

Therefore, the protection scope of the present application should be described in the protection scope of the claims.
