Description

TECHNICAL FIELD

[0001] The utility model relates to bird repelling device, especially a rice field bird repelling device. BACKGROUND

[0002] Although birds can reduce the rice field pest by preying on pests during the growth of rice, the birds belong to beneficial animals and need to be protected. However, after the rice is mature, the birds will peck the grains, affecting the yield of the rice field. The conventional bird repelling method mainly places scarecrows and plays frightening sounds. However, after long-term use, the birds will gradually adapt to the above-mentioned means, and the bird repelling effect in the later period is very unsatisfactory. Therefore, it is necessary to redesign a rice field bird repelling device to effectively expel the birds. Through research and observation, it is found that the explosion sound of firecrackers is sudden, has a wide range of propagation, and each firecracker has different explosion sound, so it is not easy for the birds to adapt, and the bird repelling effect is very obvious. However, it is obviously inefficient to assign a person to set off firecrackers at random in the rice field to repel birds. Therefore, a simple device is also designed to place a firecracker ring on incense to achieve irregular setting off of firecrackers. However, the simple device still has some problems in use. First, a disc of incense can usually only arrange firecrackers in the outermost circle, so the number of arranged firecrackers is small, and the number of firecrackers that can be ignited by burning a circle of incense is limited, and the number of times of expelling birds is limited. Second, the burning time of a circle of incense is limited (about 60-90 min), and the incense and firecrackers need to be replenished subsequently, which is very troublesome. Finally, the shock wave generated by the explosion of the firecracker is easy to break the incense and blow open the firecracker beside it, so that the stability of the simple bird repelling device is poor.

DETAILED DESCRIPTION

[0029] The technical scheme of the utility model will be described clearly and completely below in combination with the drawings, obviously, the described embodiments are a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figures 1-8 The illustrated bird deterrent device for rice paddies includes a base 1, the bottom of which is provided with a pointed cone-shaped structure that can be inserted into the soil.

[0033] A drive mechanism 2 is mounted on the base to serve as the power unit of this solution. It should be noted that the drive mechanism includes a servo motor 21 capable of precise speed control and a reducer 22 connected to the output shaft of the servo motor 21. The output shaft of the reducer extends to the upper surface of the base.

[0034] A set of ignition assemblies 3 are also installed on the base, which include a guide shaft 31 coaxially connected with the output shaft of the speed reducer 22, and two sliding grooves 31a are formed on the surface of the guide shaft and extend along the axial direction of the guide shaft, and an electric track 32 is installed in each sliding groove. It should be noted that the electric track is made of a smooth metal strip and extends along the length direction of the sliding groove. At the same time, a set of annular electrode groups A 33 are installed on the upper end of the guide shaft 31, which are made of two concentric metal rings and embedded on the end face of the guide shaft. At the same time, the two metal rings in the annular electrode group A 33 are electrically connected with the two electric tracks through wires. In addition, a slip ring 35 is sleeved and slidingly fitted on the guide shaft, and two slidingly fitted electrode sheets 36 are installed on the inner side of the slip ring and inserted into the sliding grooves, which are in smooth contact with the corresponding electric tracks to realize conduction. At the same time, a guide rod 37 is arranged on the outer surface of the slip ring, and a vertical heating wire 38 is installed on the outer side end of the guide rod, which is in conduction with the electric track through the electrode sheet. As shown in Figure 4 A guide rail 34 is also fixedly installed on the base 1, which has a double helix structure, and the guide rod 37 on the slip ring passes through the helical gap of the guide rail, so that when the slip ring is driven to rotate by the guide shaft 31, the guide rod can move along the helical track of the guide rail, thereby guiding the slip ring to make upward and downward lifting actions. In addition, it should be noted that the ignition assembly 3 in the present scheme also includes a spring clamp 39 which is elastically connected with the base 1 through a spring, and a set of annular electrode groups B 310 are installed on the top of the spring clamp, which are in conduction with the annular electrode group A at the top end of the guide shaft 31 after the spring clamp is rebounded. At the same time, the annular electrode group B is connected with the power supply 6 installed in the base through wires. When the annular electrode group A and the annular electrode group B are in conduction after the spring clamp is flipped, the heating wire 38 is electrified and heated, and the firecracker fuse in contact with the heating wire is ignited by the heating wire at this time, and the firecracker explodes immediately, making a sound and driving away the birds in the rice field.

[0035] It should be noted that in order to ensure that the heating wire rotates one circle to ignite all the external firecrackers, it is preferred that the length of the heating wire is not less than the minimum pitch of the guide rail.

[0036] As shown in Figure 2 A plurality of firecracker discharging assemblies 4 are also stacked on the base, which are mainly used to arrange the firecrackers to be ignited in a ring shape so as to be ignited one by one by the ignition assembly.

[0037] Specifically, the firecracker discharging assembly 4 comprises a bottom plate 41 and an upper cover 42, the bottom plate and the upper cover are capable of being buckled up and down, and an annular placing groove 43 is formed between the bottom plate and the upper cover after buckling. The firecrackers are arranged in the annular placing groove 43, and meanwhile, the fuse of the firecracker can extend into the firecracker discharging assembly after penetrating through the joint surface of the bottom plate 41 and the upper cover 42, so as to be contacted by the spiral heating wire. When the firecracker is ignited by the heating wire one by one, the explosion sound for driving birds can be emitted at a fixed time.

[0038] It should be noted that the firecracker will generate a shock wave when exploding, and in order to avoid the shock wave blowing the firecracker on the side out of the firecracker discharging assembly 4, a plurality of annular clamping grooves 44 are arranged on the opposite surfaces of the bottom plate and the upper cover. When the upper cover and the bottom plate are buckled, the upper and lower clamping grooves form a channel slightly larger than the firecracker. When the firecracker is placed in the channel, it will not be blown out of the firecracker discharging assembly even if it is impacted from the side.

[0039] In addition, it should be noted that in order to prevent the firecracker from exploding in the firecracker discharging assembly as much as possible, the stability is further improved. The upper surface of the bottom plate 41 in the scheme is a downward inclined conical surface. When the fuse of the firecracker burns, the firecracker discharging assembly loses the pulling effect on the firecracker, and the firecracker can slide out of the firecracker discharging assembly along the inclined surface of the bottom plate.

[0040] Meanwhile, the power supply 6 installed in the base of the scheme comprises a storage battery 61 and a solar cell panel 62 connected to the outside through wires to form the power supply 6 component in the scheme, which provides power for the movement of the driving mechanism and the heating of the heating wire in the ignition assembly. It should be noted that the solar cell panel converts solar energy into electric energy to realize self-sufficiency of the power supply in the field.

[0041] It should be noted that a controller 5 is also installed on the side of the base 1, which is electrically connected with the power supply and the driving mechanism to control the rotation speed and start-stop of the driving mechanism.

[0042] Working principle: when the rice field needs to be driven, the firecrackers are arranged in a ring in the firecracker discharging assembly, and then several firecracker discharging assemblies are stacked and sleeved outside the ignition assembly. Then, the elastic clip is turned up, and the ring electrode group B and the ring electrode group A are in contact. The heating wire is electrified to generate heat that can ignite the firecracker fuse. After the above operation is completed, the staff starts the driving mechanism through the controller, and with the action of the driving mechanism, the guide shaft in the ignition assembly rotates, and with the rotation of the guide shaft, the slip ring sleeved on the guide shaft rotates with the guide shaft because the electrode sheet is inserted in the sliding groove. With the rotation of the slip ring, the guide rod on the slip ring is guided by the guide rail to drive the sliding sleeve to rise and fall, and the rotation and lifting action of the slip ring is combined into the spiral lifting action of the heating wire, which can ignite the firecracker in the firecracker discharging assembly. With the ignition of the firecracker, the sound of the explosion can drive the birds in the rice field.

[0043] It should be noted that if irregular explosion of firecrackers is desired, several firecrackers in a ring of the firecracker discharging assembly can be removed to reduce the regularity of the explosion of the firecrackers.

[0044] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
