Description

TECHNICAL FIELD

[0001] The utility model relates to the field of aquaculture, and particularly relates to a feeding machine suitable for small shed shrimp culture. BACKGROUND

[0002] Small shed shrimp culture refers to a culture mode that builds a small shed within one mu or less to culture shrimp by taking advantage of the heat preservation and the characteristic of being free from external interference, so as to shorten the culture period and achieve quick results. The existing feeding machine for shrimp culture mainly comprises a rack, a feeding barrel fixed on the rack, a fan, a feeding pipe and an electric control box. During operation, a small amount of water is added to the feed and stirred, and then the stirred feed is put into the feeding barrel. The feed enters the feeding pipe from the discharge port of the feeding barrel, and the fan blows the feed from the feeding pipe into a pool for feeding. However, the feed after water addition and stirring will adhere to the inner wall of the feeding barrel, resulting in the formation of an arch-shaped structure that is difficult to overcome near the discharge port of the feeding barrel. The arch-shaped structure not only causes the feed to accumulate in the feeding barrel and cannot be effectively discharged, but also may cause the feed to deteriorate due to long-term retention, which is not conducive to the growth of shrimp. SUMMARY

The horizontal screw rod propelling and discharging mechanism comprises a shell. The shell is divided into an upper storage bin and a lower cylindrical feeding outer pipe. The cylindrical feeding outer pipe has a downwardly arranged discharge port. A spiral mandrel is installed in the cylindrical feeding outer pipe. A rotary motor for driving the spiral mandrel to rotate is installed on the outer side of the cylindrical feeding outer pipe. A vibrator is installed on the side wall of the storage bin.

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only 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 those skilled in the art without creative labor fall within the protection scope of the utility model.

[0020] Please refer to Figure 1 The utility model discloses a feeding machine suitable for small shed shrimp culture, which comprises a rack 11 installed on a pair of floats 10, a material cylinder 12 installed on the rack 11, a horizontal screw propelling discharging mechanism 20 and a scattering mechanism 30. The material cylinder 12 has a feeding inlet at the top and a discharging outlet at the bottom.

[0021] Combining Figure 2 As shown in the figure, the horizontal screw propelling discharging mechanism is located at the discharging outlet at the bottom of the material cylinder 12 and is used for receiving the feed output by the material cylinder 12 and conveying the feed to the scattering mechanism 30. The horizontal screw propelling discharging mechanism comprises a shell 201. The shell 201 is divided into a conical storage bin 21 at the upper part and a cylindrical feeding outer pipe 22 at the lower part. The cylindrical feeding outer pipe 22 has a downwardly arranged discharging outlet. A spiral mandrel 23 is installed in the cylindrical feeding outer pipe 22, and a rotating motor 24 for driving the spiral mandrel 23 to rotate is installed on the outer side of the cylindrical feeding outer pipe 24. A vibrator 25 is installed on the outer side wall of the storage bin 21. In this way, the feed enters the storage bin from the discharging outlet of the material cylinder, and the feed in the storage bin flows through the vibration of the vibrator, so that the feed can smoothly flow out of the discharging outlet of the storage bin and enter the cylindrical feeding outer pipe, effectively preventing the feed from arching, reducing the loss of the feed, and the spiral mandrel 23 rotates to convey the feed to the scattering mechanism.

[0022] The scattering mechanism 30 comprises a scattering nozzle 31 and a fan 32. The scattering nozzle 31 has a feeding inlet 311 communicated with the discharging outlet of the cylindrical feeding outer pipe and two lateral outward scattering spouts 312. An air inlet 313 is also arranged between the two scattering spouts 312 of the scattering nozzle. The fan 32 is installed on the rack 11, and the output end thereof is inserted into the air inlet 313.

[0023] Combination Figure 3 As shown in the figure, in this embodiment, the distribution nozzle 31 comprises a first tee joint 33, two second tee joints 34, a third tee joint 35, two distribution pipes 36, two branch pipes 37 and two connecting pipes 38. The two branch pipes 37 are obliquely arranged, the feeding ends of the two branch pipes 316 are connected with the two joints of the first tee joint 33 respectively, and the other joint of the first tee joint 317 forms an inlet port 311 and is connected with the outlet port of the cylindrical feeding outer pipe. The outlet ends of the two branch pipes 37 are connected with the two second tee joints 34 respectively. The first joints 341 of the two second tee joints 34 are connected with one end of the distribution pipe 36 respectively, the second joints 342 obliquely arranged with the first joints 341 are connected with the outlet ends of the corresponding branch pipes 37, and the third joints 343 opposite to the first joints 341 are connected with the corresponding connecting pipes 38. The other ends of the two distribution pipes 36 form two distribution spouts 312 of the distribution nozzle 31. The two connecting pipes 38 are connected together through the third tee joint 35. The third joint of the third tee joint 35 perpendicular to the first joint and the second joint forms an air inlet 313, and the output end of the fan 32 is inserted into the air inlet 313.

[0024] A control box 40 is fixed on the frame 11. A controller is arranged in the control box 40. The rotary motor 24, the fan 32 and the vibrator 25 are electrically connected with the controller. A charging battery 41 is also arranged in the control box 20 to provide power for the controller, the rotary motor 24, the fan 32 and the vibrator 25. The working voltage (lower than 24V) of the charging battery 41 is low, so that no electric shock protection measures are needed, and the danger of electric shock is avoided when the breeder operates. Here, the remote controller can be used to remotely control the controller to realize automatic feeding control. The distance of the feed distribution is controlled by controlling the air volume of the fan. At the same time, the controller controls the rotary motor 24, the fan 32 and the vibrator 25 to automatically start, the interval time of starting and the starting time, so as to realize scientific breeding.

[0025] As Figure 1As shown, the walking driving mechanism 50 for driving the floating body 10 to move on water is also included. The walking driving mechanism 50 includes an upper pressing wheel 51 and a lower pressing wheel 52 arranged on the frame 11. A gap is provided between the upper pressing wheel 51 and the lower pressing wheel 52 for the traction wire 53 to pass through. The traction wire 53 is located in the gap. Fixed pegs 54 are fixed on the shore on both sides of the pool. The two ends of the traction wire 53 are fixed on the corresponding fixed pegs 54. A driving motor 55 is also fixed on the frame 11 for driving the lower pressing wheel 52 to rotate. In the embodiment, the upper pressing wheel 51 is a concave wheel and the lower pressing wheel 52 is a convex wheel. During operation, the driving motor 55 drives the lower pressing wheel 52 to rotate. The friction between the rotating lower pressing wheel 52 and the traction wire 53 drives the lower pressing wheel 52 to move linearly along the traction wire 53, thereby driving the floating body 10 to move linearly along the traction wire 53. The upper pressing wheel 51 can apply pressure to the traction wire, thereby avoiding the traction wire from deviating or vibrating.

[0026] In combination Figure 4 As shown, in the embodiment, an annular guide groove 56 is arranged on the circumferential surface of the lower pressing wheel 52. The traction wire 53 is located in the guide groove 56. With the above structure, the traction wire is located in the guide groove, thereby further preventing the traction wire from deviating.

[0027] The above is a feeding machine suitable for small shed shrimp culture. The working mode is as follows:

[0028] During operation, the feed is stirred with water and then loaded into the barrel 12. Subsequently, the driving motor 55 is started to drive the lower pressing wheel 52 to rotate. The friction between the rotating lower pressing wheel 52 and the traction wire 53 drives the lower pressing wheel 52 to move linearly along the traction wire 53, thereby driving the floating body 10 to move linearly along the traction wire 53. At the same time, the controller is controlled by the remote controller to start the rotating motor, the vibrator and the fan. The feed is discharged from the lower end of the barrel 12, falls into the cylindrical feeding outer tube 22 through the storage bin, and then is conveyed to the discharge port of the cylindrical feeding outer tube 22 by the rotation of the spiral mandrel. Subsequently, the feed freely falls into the spreading nozzle 31 and is finally blown into the pool by the fan.

[0029] When it is needed to move the equipment from the water surface to the shore, the driving motor 55 is controlled to drive the lower pressing wheel 52 to rotate. The friction between the rotating lower pressing wheel 52 and the traction wire 53 drives the lower pressing wheel 52 to move linearly along the traction wire 53, thereby driving the floating body 10 to move along the traction wire 53.

[0030] The above has carried out the detailed description to one embodiment of the utility model, but the content described is only the preferred embodiment of the utility model, cannot be considered for limiting the implementation scope of the utility model. All equal changes and improvements etc. that are made in the utility model application scope should still belong to the patent coverage scope of the utility model.
