Detailed Description

As shown in fig. 1 to 9, the present invention mainly includes a bottom plate 1, a spring plate 2, a feeding pipe 3, and a driving mechanism, and the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, the bottom plate 1 is a rectangular plastic piece, a mounting rod 11 is fixed on the rear side of the bottom plate, and a spring plate 2 arranged above the bottom plate is fixed on the mounting rod. As shown in fig. 3, the elastic sheet includes an installation section 21, an ejection section 22 and a driving section 23, which are sequentially arranged from back to front, wherein the installation section is linear, and the installation section is fixed on the installation rod through screws. The ejection section is integrally conical and is formed by bending a metal sheet. The driving section is of an arc-shaped structure, and the mounting section, the ejection section and the driving section can be integrally formed, namely, the driving section is formed by bending a metal sheet. When the driving section of the elastic sheet is stirred, the ejection section can move. In order to keep the shape of the ejection section, a reinforcing plate 25 is arranged on the inner side of the ejection section, and two ends of the reinforcing plate are in contact with and fixed on the inner wall of the ejection section.

Be fixed with on the bottom plate and throw in pipe 3, throw and put the pipe for the plastics pipe, as shown in fig. 2, throw the first end of pipe and be fixed with extension 31, throw in the pipe horizontal setting, the extension is vertical to be placed and is put in the pipe perpendicularly. The extension pipe is C shape, and the bee ball falls in throwing the first end of putting the pipe after getting into the extension pipe, throws the second end of putting the pipe and stretches out bottom plate one section. Under the natural state, the small end of the ejection section extends into a part of the extension pipe, and the bee ball cannot fall into the throwing pipe at the moment. The drive section is shifted to enable the ejection section to move from the extension pipe to the opening, and bee balls can be added into the extension pipe at the moment. The lower wall of the inner cavity of the throwing tube is provided with an inclined surface 32, the lower end of the inclined surface is positioned at one side of the extension tube, and the arrangement of the inclined surface can prevent bee balls from automatically moving out of the throwing tube.

A main shaft 4 is rotatably arranged on the bottom plate for shifting a driving section of the elastic sheet, a rotating wheel 41 is fixed on the main shaft, and a shifting rod 42 is fixed on the outer wall of the rotating wheel; when the driving main shaft rotates, the rotating wheel can be driven to rotate, and then the driving lever is driven to rotate, and after the driving lever is in contact with the driving section, the driving section on the elastic sheet can be stirred, and then the ejection section is moved out of the extension pipe. Along with the rotation of runner, the driving section is kept away from gradually to the driving lever until with the separation of driving section, and the shell fragment resets under self elasticity effect afterwards, and ejection section gets back to in the extension pipe.

As shown in fig. 4, the deflector rod pulls the driving section to make the ejection section leave the extension pipe, and then the bee balls 5 automatically fall into the extension pipe; as shown in fig. 5, the shift lever is separated from the driving section, the driving section resets to drive the ejection section to reset, and the ejection section contacts with the bee balls to eject the bee balls at a certain initial speed. At the moment, the bee balls move along the throwing pipe and fly out until the bee balls fall into the field.

As shown in figure 6, in order to add bee balls into the extension pipe, a storage box 6 is arranged above the extension pipe, as shown in figure 7, the storage box is of a cylindrical structure with an open upper end, a circular lug plate 61 is fixed at the top of the storage box, a mounting hole 62 is formed in the lug plate, a bolt is arranged in the mounting hole, and the storage box is mounted on the walking equipment through the lug plate. A side pipe 63 is fixed to a side wall of the storage tank, and the side pipe is disposed obliquely with a lower end thereof in contact communication with the storage tank. A stirring shaft 64 is rotatably arranged in the inner cavity of the storage box, and two stirring sheets 65 are fixed on the outer wall of the stirring shaft and are arranged in a V shape. The bottom of the storage box is provided with a falling hole 66, two cavities which are independent from each other are defined by the two stirring sheets and the inner wall of the storage box, and the two cavities are a first cavity and a second cavity respectively. Bee balls are added into the first cavity, the stirring sheet pushes the bee balls to move along with the rotation of the stirring shaft, and the bee balls in the first cavity fall through the falling hole. A connection pipe 68 communicating with the dropping hole is fixed to the bottom of the storage box, and the lower end of the connection pipe is butted with or screwed with the extension pipe, so that the bee balls in the storage box can drop into the connection pipe through the dropping hole and finally fall into the extension pipe. A stirring motor 67 is fixed to the bottom of the storage tank and drives the stirring spindle to rotate. The storage box, the stirring shaft, the stirring blades and the stirring motor are used for continuously adding the bee balls into the extension pipe, and the rotating wheel continuously rotates to eject the bee balls falling into the extension pipe through the feeding pipe.

As shown in fig. 9, two bottom plates may be provided, and at this time, the two bottom plates are fixedly mounted on the fixing plate 7 and symmetrically arranged, and the fixing plate is fixedly connected with the storage box. Like this, through setting up two and throwing the pipe, can throw in bee ball respectively simultaneously to left side and right side to improve bee ball's input efficiency.

The throwing mechanism can be installed on an aircraft or other advancing equipment, and can be used for throwing the bee balls while walking.
