Description

Technical Field

[0001] The utility model relates to the field of factory breeding of aquatic products, in particular to a pneumatic bait throwing device. Background Art

[0002] When aquatic products are farmed in factories, it is necessary to put bait into the breeding ponds at regular intervals and in fixed quantities. In order to prevent the aquatic products from being too concentrated and to improve the utilization rate of the bait, the bait needs to be spread as evenly as possible. However, traditional methods are mostly manual operations, which make it difficult to achieve uniform spreading and require a lot of manpower, resulting in relatively low work efficiency.

[0003] In order to solve the above problems, there are now some automated feeding devices that use high-pressure air to blow bait to achieve spreading. However, in order to achieve long-distance and uniform bait spreading, these feeding devices have to use relatively large-power fans to provide high-pressure wind, which will result in a larger overall size and higher cost of the feeding device.

[0004] Therefore, a method or device capable of solving the above problems is now needed. Summary of the invention

[0005] The utility model aims to solve the above-mentioned deficiencies in the prior art and proposes a pneumatic bait throwing device which has a simple structure, ingenious design, reasonable layout and can obtain a better uniform spraying effect under the condition of effectively controlling the cost.

[0006] The technical solution of the utility model is: a pneumatic bait throwing device, characterized in that: the device comprises a shell 1, a wheel 12 is arranged at the bottom of the shell 1, a feed hopper 2 is arranged in the shell 1, the top opening of the feed hopper 2 is located on the top plate of the shell 1, the bottom outlet of the feed hopper 2 is connected to the inlet of the quantitative mechanism 3, and the outlet of the quantitative mechanism 3 is connected to the inner cavity of the Laval tube 4 located therebelow, a fan 5 is also arranged in the shell 1, the outlet end of the fan 5 is connected to the inlet end of the Laval tube 4, the outlet end of the Laval tube 4 is divided into two paths, the ends of the two paths are both connected to a discharge hose 6,

[0007] The quantitative mechanism 3 includes a quantitative mechanism housing 7, in which a rotating shaft is rotatably supported, and a spiral blade 8 is arranged on the rotating shaft. One end of the rotating shaft is connected to the output end of the motor 9. An inlet channel 10 is arranged on the top plate of the quantitative mechanism housing 7, and an outlet channel 11 is arranged on the bottom plate. The inlet channel 10 is connected to the bottom outlet of the feed hopper 2, and the outlet channel 11 is connected to the Laval tube 4. At the same time, the inlet channel 10 and the outlet channel 11 are respectively located at the two ends of the quantitative mechanism housing 7.

[0008] Compared with the prior art, the utility model has the following advantages:

[0009] This pneumatic feeding device has a simple structure, ingenious design and reasonable layout. It is designed to solve the problems existing in the use of traditional feeding devices. A special structure is designed. A quantitative mechanism is set below the feed hopper. The quantitative mechanism can accurately control the amount of each feeding operation, and the outlet of the quantitative mechanism is connected to a Laval tube connected to a fan at one end. When the fan is started, the bait falling into the Laval tube can be sprayed into the breeding pond through the discharge hose. Due to the setting of the Laval tube, the wind flow rate can be accelerated, so that the bait can be spread farther and more evenly. That is to say, when using a fan of the same power, this device can obtain a better feeding effect. In addition, the manufacturing process of the device is simple and the manufacturing cost is low. Therefore, it can be said that it has many advantages and is particularly suitable for promotion and application in this field. Its market prospects are very broad. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 2 It is a structural schematic diagram of the quantitative mechanism in the embodiment of the utility model. DETAILED DESCRIPTION

[0012] The specific implementation of the present utility model will be described below in conjunction with the accompanying drawings. Figure 1 , Figure 2 As shown: a pneumatic bait throwing device, which includes a shell 1 as a basis, a wheel 12 is arranged at the bottom of the shell 1, a feed hopper 2 is arranged in the shell 1, the top opening of the feed hopper 2 is located on the top plate of the shell 1, the bottom outlet of the feed hopper 2 is connected to the inlet of the quantitative mechanism 3, and the outlet of the quantitative mechanism 3 is connected to the inner cavity of the Laval tube 4 located below it, and a fan 5 is also arranged in the shell 1, the outlet end of the fan 5 is connected to the inlet end of the Laval tube 4, and the outlet end of the Laval tube 4 is divided into two paths, and the ends of the two paths are connected to a discharge hose 6,

[0013] The quantitative mechanism 3 includes a quantitative mechanism housing 7, in which a rotating shaft is rotatably supported, and a spiral blade 8 is arranged on the rotating shaft. One end of the rotating shaft is connected to the output end of the motor 9. An inlet channel 10 is arranged on the top plate of the quantitative mechanism housing 7, and an outlet channel 11 is arranged on the bottom plate. The inlet channel 10 is connected to the bottom outlet of the feed hopper 2, and the outlet channel 11 is connected to the Laval tube 4. At the same time, the inlet channel 10 and the outlet channel 11 are respectively located at the two ends of the quantitative mechanism housing 7.

[0014] The working process of the pneumatic feeding device of the embodiment of the utility model is as follows: a sufficient amount of bait is poured into the feed hopper 2 in advance, and the bait enters the quantitative mechanism housing 7 below the feed hopper 2 along the outlet thereof, and the housing 1 is pushed to move to the edge of the breeding pond, and then the device is controlled to work through the control system;

[0015] When the device is working, the motor 9 drives the spiral blade 8 to rotate a certain number of times, and the bait enters the Laval tube 4 through its outlet channel 11 under the conveyance of the spiral blade 8. When the output number of the motor 9 reaches a preset value, it means that the bait entering the Laval tube 4 has reached a preset amount. At this time, the motor 9 stops working, and the fan 5 works to blow the bait into the discharge hose 6, and finally spreads it into the breeding pond through the discharge hose 6, thereby realizing the quantitative delivery of bait.

[0016] Since the Laval tube 4 is used in the device, the wind speed at the outlet can be effectively increased. That is to say, when the fan power is constant, the device can spread the bait farther and more evenly. That is to say, when using a fan of the same power, the effect of the device is better.
