Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to a feed mixing device used in aquaculture. Background Technology

[0002] Aquaculture is a production activity that uses water resources to cultivate aquatic plants and animals artificially. It mainly includes two types: freshwater aquaculture and marine aquaculture. The use of feed is indispensable in the process of aquaculture, and feed processing requires feed mixing equipment.

[0003] Currently, the feed mixing equipment used in aquaculture is significantly different from that used in other industries (such as animal husbandry, food processing, and chemicals). These differences mainly stem from the special properties of aquaculture feed, the needs of the aquaculture environment, and the requirements of the mixing process. Aquaculture feed often contains powders (such as fish meal and minerals), pellets (such as soybean meal pellets), and liquids (such as oils and vitamin premixes). Furthermore, the particle size of feed varies greatly among different aquaculture species (such as fish fry, adult fish, and shrimp and crab) (fish fry feed may be as fine as 80 mesh, while adult fish feed may be 2-5 mm particles).

[0004] However, existing feed mixing devices used in aquaculture are prone to causing stratification of the mixed feed due to differences in the density of feed components, such as fishmeal (density approximately 0.8 g / cm³). 3 ), bran (approximately 0.3g / cm³) 3 ), minerals (such as calcium phosphate, approximately 2.8 g / cm³) 3 The density of materials such as fish feed varies greatly, and the nutritional balance of fish feed directly affects the growth of aquatic animals. Furthermore, uneven mixing of trace components (such as drugs and enzymes) may lead to poisoning or poor growth of farmed species. Therefore, we propose a feed mixing device for fish farming.

[0026] Example 1

[0027] Please see Figures 1-4 As shown, this utility model provides a technical solution: a feed mixing device for aquaculture, comprising:

[0028] A base plate 1, a bracket 101 is fixedly installed at the right end of the top of the base plate 1, a lower box 102 is fixedly installed on the inner side of the bracket 101, an upper box 103 is provided on the top of the lower box 102, and a screen cylinder 105 is fixedly connected to the top of the inner side of the upper box 103.

[0029] The conveying cylinder 2 is fixedly installed between the top left end of the base plate 1 and the top of the upper box 103. A guide pipe 203 is connected between the bottom right end of the conveying cylinder 2 and the top left end of the upper box 103.

[0030] The premixed motor 3 is fixedly installed at the middle of the top of the upper housing 103. The output end of the premixed motor 3 is fixedly connected to a premixed rotating shaft 301 that moves within the screen cylinder 105 via a bearing.

[0031] The mixing motor 4 is fixedly installed at the middle of the bottom of the lower housing 102. The output end of the mixing motor 4 is fixedly connected to the mixing shaft 401 that rotates inside the lower housing 102 through a bearing.

[0032] A discharge pipe 104 is provided at the lower end of the right side of the lower housing 102, and a valve body is provided at the upper end of the discharge pipe 104. A toggle scraper 304 and a connecting rod 302 are fixedly connected to the outer surface of the premixing shaft 301. A crushing ball 303 is fixedly connected to one end of the connecting rod 302. The outer side of the toggle scraper 304 is in contact with the inner wall of the screen cylinder 105. A mixing rod 403 is fixedly connected to the upper end of the outer surface of the mixing shaft 401, and a pusher impeller 402 is fixedly connected to the lower end of the outer surface of the mixing shaft 401.

[0033] This technical solution: During use, it is necessary to check whether the equipment is functioning normally. If everything is normal, mains power is supplied to the device via the main control switch. When the material to be mixed is conveyed into the upper housing 103 through the conveying cylinder 2, the device is started by an external controller (existing technology). Then, the conveying impeller inside the conveying cylinder 2 rotates, thus spirally conveying the material to be mixed upwards. During this conveying process, the material is pre-mixed once. Next, the material enters the screening cylinder 105 inside the upper housing 103 through the guide pipe 203. When the premixing motor 3 drives the premixing shaft 301 to rotate, the premixing shaft 301 drives the actuating scraper 304 and connecting rod 302 to rotate. The connecting rod 302 then drives the crushing ball 303 to rotate, thus achieving premixing of the incoming material while also performing screening. Agglomerated material is screened (because aquaculture is mostly distributed along...). In humid environments such as seas and lakes, materials often clump together due to moisture. The rotating connecting rod 302 and crushing ball 303 can crush lumpy materials, ensuring the uniformity of material mixing. After the pre-mixed material enters the lower box 102, the mixing motor 4 drives the mixing shaft 401 to rotate. When the mixing shaft 401 rotates, it drives the push impeller 402 and mixing rod 403 to rotate. The rotating push impeller 402 can push the material at the lower end of the inner cavity of the lower box 102 upwards, while the rotating mixing rod 403 can mix the material pushed upwards by the push impeller 402 with the material falling from the screen cylinder 105. Under the influence of gravity, the material moves along the inner wall of the lower box 102 to the lower end of the inner cavity of the lower box 102, and is then pushed upwards again by the push impeller 402. This cycle ensures thorough mixing of the material and avoids stratification and clumping.

[0034] It should be noted that the conveying cylinder 2, premixing motor 3 and mixing motor 4 used in this device can all be purchased directly from the market. At the same time, the connection method and electrical connection relationship of each component adopt mature conventional methods in the existing technology, so they will not be described in detail here.

[0035] Example 2

[0036] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, an electric heating jacket 201 is provided on the outer surface of the conveying cylinder 2, and a feeding hopper 202 is provided at the left end of the conveying cylinder 2.

[0037] This technical solution: By setting up the electric heating jacket 201, when the electric heating layer inside the electric heating jacket 201 is turned on by an external controller (which belongs to the prior art), the electric heating jacket 201 can heat the conveying cylinder 2, thereby enabling the conveying cylinder 2 to heat and dehumidify the material when conveying it. This is beneficial for mixing materials in humid environments, thus preventing the material from clumping. (The use of the electric heating jacket 201 is selective; for example, it cannot be heated when adding probiotics.)

[0038] It should be noted that the electric heating jacket 201 used in this device can be purchased directly from the market, and its electrical connection relationship adopts the mature conventional methods in the existing technology, so it will not be described in detail here.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
