Technical Field
[0001] This utility model belongs to the field of shrimp pond aquaculture feeding technology, specifically relating to a semi-automatic shrimp feeder. Background Technology
[0002] Shrimp pond farming in my country is large-scale, and technologies such as aeration and disease control are quite mature. However, feeding remains a relatively traditional method, involving scattering feed in plastic buckets along the pond's perimeter. This method has several problems: firstly, as the feeding volume increases in the later stages of farming, it becomes time-consuming, labor-intensive, and increases labor costs; secondly, uneven scattering affects feed utilization, easily pollutes the pond water, and can lead to disease outbreaks and economic losses. Feeding machines, on the other hand, are time-saving, labor-saving, and significantly improve work efficiency, thus gaining widespread use.
[0003] Currently, the feeding machines used in pond aquaculture in my country are basically fixed at one point in the pond, with a spreading range of about 50m. 2 These feeding machines are only suitable for fish ponds. Because shrimp require feeding along the perimeter of the pond due to their natural feeding habits, these machines are not suitable for shrimp ponds.
[0004] Although there are already fully automatic shrimp feeders on the market, their usage rate in shrimp farming is very low because they also have some obvious disadvantages: (1) They are expensive, costing six to seven thousand yuan per unit, and each pond needs one unit, which is costly; (2) As they are fully automatic equipment, they are highly electronic and have many electronic components, which leads to a higher failure rate and higher maintenance costs. Utility Model Content
[0005] In view of the above-mentioned defects in the current shrimp pond feeding methods, this utility model provides a semi-automatic shrimp feeder that is simple to manufacture, low in cost, easy to operate, and convenient to use, so as to improve work efficiency, reduce breeding costs, and is of great significance to promoting the development of the shrimp farming industry.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A semi-automatic shrimp feeder includes a hull, a frame fixed to the hull, a propulsion motor, a hopper fixed within the frame, and a discharge control system, wherein:

[0010] The present invention is further configured such that the propulsion motor is located at the stern of the hull and includes an electric motor and a propeller.
[0011] The present invention is further configured such that a screw hole is provided in the middle of the control lever, the screw hole being circular or rectangular, and the screw passing through an L-shaped galvanized iron sheet on one side, the screw hole of the control lever, and an L-shaped galvanized iron sheet on the other side in sequence.
[0012] The present invention is further configured such that a set of limiting rings is fixedly arranged on the right side of the lever, a crossbar is inserted through the limiting rings, the two ends of the crossbar are bent and its diameter is smaller than the diameter of the limiting rings, and the middle part of the crossbar is fixedly connected to the bottom end of the control lever.
[0013] The present invention is further configured such that the limiting ring is a nut or a round tube.
[0014] The present invention is further configured such that a plurality of pulleys are provided at the bottom of the paddle, and tracks matching the pulleys are provided on both sides of the square hole of the hull.

[0019] The beneficial effects of this utility model are as follows:
[0020] 1. Compared with manual feeding, the semi-automatic shrimp feeder of this utility model is significantly simpler to operate, requiring no professional training and can be operated by ordinary workers.

Detailed Implementation
[0032] The technical solution of this utility model will be clearly and thoroughly described below with reference to the accompanying drawings and specific embodiments. It should be understood that the following embodiments are only some embodiments of this utility model and are not intended to limit the protection scope of this utility model.
[0033] In response to the problems of high labor intensity and low feed utilization rate of manual feeding, and high cost, complex structure and high failure rate of fully automatic feeders, the inventors of this application obtained the semi-automatic shrimp feeder after multiple experiments, taking into account the effective load-bearing capacity of the hull, operational flexibility, convenience of operation on the hull, power performance, feed delivery and hull movement speed, and manufacturing cost.
[0034] like Figure 1 and Figure 2 As shown, a semi-automatic shrimp feeder of this utility model includes a hull 10, a frame 20 fixed on the hull 10, a propulsion motor 30, a hopper 40 fixed inside the frame 20, and a discharge control system 50, wherein:
[0035] Combination Figure 3 and Figure 4 As shown, the upper part of the frame 20 is provided with a U-shaped slot 21, and a pair of L-shaped galvanized iron sheets 22 are arranged opposite each other in the middle to form an opening 23;
[0036] The bottom of the hopper 40 is provided with a discharge port 41;
[0037] The hull 10 is provided with a square hole 11 corresponding to the discharge port 41, and the feed in the hopper 40 enters the water directly through the square hole 11.
[0038] The discharge control system 50 includes a paddle 51 located between the discharge port 41 of the hopper 40 and the square hole 11 of the hull 10, and an operating lever 52 movably connected to the paddle 51. The upper end of the operating lever 52 is located in the U-shaped slot 21, and the middle part is located in the opening 23 and connected to the screw 53 (e.g., Figure 4 (As shown) is rotatably connected to the L-shaped galvanized iron sheet 22; the amount of feed can be effectively controlled by pushing the control lever 52 back and forth.
[0039] In some embodiments, such as Figure 2 As shown, the propulsion motor 30 is located at the stern of the hull 10 and includes a motor 31 and a propeller 32. After the feed enters the water, it is sprayed out by the propeller 32 to achieve uniform spraying of the feed, thereby improving the utilization rate of the feed.
[0040] In some embodiments, such as Figure 4 and Figure 5As shown, a screw hole 54 is provided in the middle of the control lever 52. The screw hole 54 is circular or rectangular. The screw 53 passes through the L-shaped galvanized iron sheet 22 on one side, the screw hole 54 of the control lever 52 and the L-shaped galvanized iron sheet 22 on the other side in sequence. The control lever 52 can rotate flexibly around the screw 53 in the opening 23. When the screw hole 54 is rectangular, the control lever 52 can also move up and down in the opening 23.
[0041] In some embodiments, such as Figure 6 As shown, a set of limiting rings 55 are fixedly arranged on the right side of the lever 51. A crossbar 56 is inserted through the limiting ring 55. The two ends of the crossbar 56 are bent and its diameter is smaller than that of the limiting ring 55, so that it can move freely within the limiting ring 55. The middle part of the crossbar 56 is fixedly connected to the bottom end of the control lever 52. The limiting ring 55 is a nut or a round tube.
[0042] In some embodiments, when there is too much feed in the hopper 40, the resistance to pushing the control lever 52 is large. To facilitate worker operation, such as... Figure 7 and Figure 8 As shown, the bottom of the lever 51 is provided with several pulleys 57, and the sides of the square hole 11 of the hull 10 are provided with tracks 12 that match the pulleys 57. The pulleys 57 move within the tracks 12 to reduce friction and lower operating resistance.
[0043] In some embodiments, the frame 20 includes a plurality of horizontal tubes, a plurality of vertical tubes and a vertical shaft for connecting and fixing the horizontal tubes to each other.
[0044] In some embodiments, the hull 10 is made of foam sandwich panel, and the hull 10 has a length of 280-320cm, a width of 130-170cm, and a thickness of 20-30cm; preferably, the hull 10 has a length of 300cm, a width of 150cm, and a thickness of 25cm. Choosing a suitable hull length facilitates worker operations; a suitable hull thickness helps increase the draft of the hull 10, achieving an effective load capacity of 150kg-200kg, thus improving safety. Especially in situations requiring large amounts of feed later, feeding can be completed in one go without the need for batch feeding, improving feeding efficiency.
[0045] In some embodiments, the hopper 40 is a square funnel shape, welded from stainless steel, and has a length of 65cm, a width of 65cm, and a height of 60cm.
[0046] In some embodiments, the square hole 11 is 5cm × 5cm in size to facilitate the conveying of feed.
[0047] In some embodiments, the propulsion motor 30 is a marine power motor, preferably with a power of 48 lbs, and equipped with a 12-volt battery.
[0048] In some embodiments, the hull 10 is further provided with a seat between the hopper 40 and the push motor 30 to facilitate worker operation.
[0049] When using the aforementioned semi-automatic shrimp feeder, the worker sits on the hull 10, puts the feed into the hopper 40, and starts the feeder. The worker controls the feeder by moving the lever 52 and the paddle 51 back and forth, effectively controlling the feed amount. Specifically, pushing the lever 52 forward increases the feed amount, while pushing it backward decreases it. The feed enters the water directly from the bottom of the hull 10 and is dispersed by the propeller 32 of the propulsion motor 30. Multiple tests have shown that controlling the feeder's operating speed at 30 km / h results in the most even feed distribution and the highest feed utilization rate.
[0050] Application Examples
[0051] This application trial was conducted from April to September 2018 at a pond base in Shanghai. Experimental ponds and control ponds were set up, with the same seedling source, stocking quantity, stocking time, and feed brand. Each pond was managed by a dedicated worker.
[0052] 1. Experimental procedure:
[0053] Pond selection: Ponds 1-5 are experimental ponds, each 8.6 mu (approximately 1.4 hectares), totaling 43 mu (approximately 3.5 hectares); Ponds 6-8 are control ponds, each 8.6 mu (approximately 1.4 hectares), totaling 25.8 mu (approximately 1.6 hectares). The ponds have convenient water inlet and outlet and complete supporting facilities.
[0054] Shrimp larvae were introduced into the ponds on May 15th. Due to the small size of the shrimp and low feed intake in the first month, manual feeding was used. Starting June 16th, the experimental ponds were fed using the semi-automatic shrimp feeder described in this application, with one machine per pond. Control ponds were fed manually. During the rearing period, microbial preparations were regularly used to condition the water quality, and water quality indicators were regularly tested. Throughout the rearing cycle, the pH was controlled at 8.0-8.6, ammonia nitrogen <0.6 mg / L, nitrite <0.1 mg / L, and dissolved oxygen >5 mg / L. No diseases occurred during this period. After more than four months of rearing, all shrimp were harvested by the end of September.
[0055] 2. Test Results:
[0056] (1) Labor costs are reduced dramatically and feeding efficiency is greatly improved.
[0057] In a single breeding cycle, the experimental ponds using a semi-automatic shrimp feeder took about 15 minutes to feed each pond, with a total of 5 experimental ponds (43 mu) fed at a time. The workers found this process very easy. However, when using manual feeding, the feeding time per pond was about 20 minutes in the early and middle stages due to the smaller amount of feed. In the later peak feeding period, the feeding time per pond was about 40 minutes, and the workers had to feed 3 ponds (25.8 mu) at a time, which was very labor-intensive and strenuous for them.
[0058] As can be seen from the above, by using the semi-automatic shrimp feeder of this application, a full-time worker can increase the feeding pond area from 25.8 mu to 43 mu while reducing labor intensity. The average labor cost per mu is reduced by 40%. At the same time, during the peak feeding period, the feeding time for each pond can be shortened from 40 minutes to 15 minutes, which is 62.5% shorter and feeding efficiency is greatly improved.
[0059] (2) The feed conversion ratio decreased
[0060] The yield per mu and feed conversion ratio (feed amount / yield per mu) of experimental ponds 1-5 and control ponds 1-3 are shown in Table 1 below:
[0061] Table 1
[0062]
[0063] As shown in Table 1, the average yield per mu of the experimental pond and the control pond were 442.2 kg and 422.5 kg, respectively, and the average feed conversion ratios were 1.06 and 1.17, respectively. The average yield per mu of the experimental pond increased by 19.7 kg, and the feed conversion ratio was significantly lower than that of the control pond.
[0064] The above differences exist because artificial feeding is affected by climate and feeding techniques. For example, feeding against the wind in windy weather can easily cause feed to be blown to shallow waters or the shore; when workers' feeding techniques are not good, the feed is easy to clump together and difficult to disperse. These factors can easily lead to feed waste, resulting in a higher feed conversion ratio.
[0065] When using the semi-automatic shrimp feeder of this application, the feed enters the water directly from the bottom of the boat and is sprayed out by the propeller, which effectively avoids the drawbacks of manual feeding. The feeding point is precise and the spraying is uniform, increasing the utilization rate of the feed.
[0066] The above embodiments have described the technical solution of this application in detail, but they are not intended to limit the protection scope of this utility model. All equivalent substitutions made within the principles and spirit of this application are within the protection scope of this utility model.
