Description

Technical Field

[0001] The invention relates to the technical field of crushing equipment, in particular to a bait crushing device with a feeding function for aquaculture. Background Art

[0002] Aquaculture refers to the mass reproduction of aquatic plants and animals under artificial control, generally including the whole process of growing aquatic products from seedlings under artificial feeding and management. Aquatic products are rich in various nutrients and are deeply loved by people. People's demand for aquatic products is also increasing. With the development of aquaculture, fish feed with simple production methods, low ingredients and good feeding effects is becoming more and more popular. In the process of aquaculture, a large amount of aquatic feed is needed to assist in breeding work, because it is necessary to ensure the various nutrients required for fish growth. At the same time, mature fish need to eat more bait due to their large size. It is obviously difficult to meet the breeding needs by manual processing alone.

[0003] In the current aquatic feed processing process, the crushing work is usually carried out by crushing equipment, and generally a simple crushing method such as a cutting knife and a crushing roller is used to crush the bait. However, the structure of the traditional aquatic feed processing crushing device is relatively simple. There is also a multifunctional crushing device for aquatic feed production such as CN207941601U, which includes a feeding device, a fixing frame, a feeding port, a flip cover, a stirring frame, a discharging device and a pad. A barrel cover is arranged on the lower side of the feeding device, and the feeding device is connected to the crushing chamber through the barrel cover. A crushing barrel is arranged on the inner side of the crushing chamber. A rotating shaft is arranged on the right side of the crushing cylinder, a screen is installed on the lower side of the flip cover, and a stirring chamber is arranged at the bottom end of the screen, a rotating disk is arranged on the lower side of the stirring frame, and the stirring frame is connected to the second motor through the rotating disk, a base frame is inlaid on the upper side of the discharging device, and the discharging device is connected to the stirring chamber through the base frame, a supporting rod is arranged on the lower side of the pad, and a supporting foot is fixedly connected to the bottom end of the supporting rod, and the crushing and material mixing effects are further improved by combining the single raw material crushing device currently used in the production of aquatic feed with structural and functional innovations.

[0004] However, the additional independent stirring mechanism of this type of equipment increases the cost of use. In addition, in addition to the simple structure, the functions are still relatively simple. For example, bait delivery usually still requires manual throwing. Some existing air pump-type bait delivery equipment has high costs, and the feeding and delivery type is prone to equipment blockage. At the same time, the equipment is not flexible to use and is mostly only used for fixed-point delivery. It is not convenient to adjust the scope of the bait delivery area. In order to facilitate the rapid crushing and flexible delivery of fresh bait, in-depth research was conducted on the above-mentioned problems, which led to the creation of this case. Summary of the invention

[0005] The purpose of the present invention is to provide a bait crushing device with a feeding function for aquaculture, so as to solve the problems raised in the above background technology that the structure and function of the aquatic feed processing and crushing device are relatively simple, and it is not convenient to quickly crush and flexibly feed fresh bait.

[0021] Preferably, a locating pin is provided through the side of the lifting support foot, and a pin hole structure corresponding to the locating pin is distributed on the surface of the movable frame, and the locating pin is synchronously provided through the lifting support foot and the movable frame.

[0022] By adopting the above technical solution, the support height limit adjustment of the lifting legs through the positioning pin can facilitate the maintenance of the overall support inclination angle of the equipment, which is convenient for adjusting the angle of throwing and feeding, and a certain inclination angle can also facilitate unloading.

[0023] Preferably, the main body of the rotary spreading mechanism is a spreading wheel, and movable blades are arranged on the periphery of the spreading wheel, and the movable blades are movably fitted with the inner wall of the feeding tray.

[0028] By adopting the above technical solution, the symmetrically arranged side movable baffles can provide a larger adjustment area, which is convenient for flexible adjustment and use.

[0029] Preferably, a mounting boss is integrally provided on the upper surface of the feeding tray, and a driving motor is installed above the mounting boss, and a driving shaft is provided between the driving motor and the rotating throwing mechanism;

[0030] The drive shaft passes through the mounting boss, and the middle section of the drive shaft is a crankshaft section, and the crankshaft section is located inside the mounting boss. The crankshaft section is movably connected to the crankshaft connecting rod to form a connecting rod reciprocating structure.

[0031] By adopting the above technical solution, the rotary spreading mechanism and the synchronous reciprocating mechanism can be driven synchronously by a single motor, which reduces costs and saves energy.

The specific structural advantages include:

[0033] 1. A rotating throwing mechanism is set up. The bait is moved by the movable blades. Under the action of centrifugal force, the bait can be thrown evenly over a large area in an arc shape from the feeding port, imitating the way of manual throwing. The bait throwing is more uniform. At the same time, combined with the opening and closing adjustment of the movable baffle on the side of the feeding port, the material throwing area can be further flexibly adjusted, which is convenient and practical;

[0034] 2. A feeding baffle is provided which is synchronously driven with the synchronous reciprocating mechanism. During the use of the equipment, no additional driving equipment is required. While the driving shaft drives the rotating throwing mechanism, the crankshaft section can cooperate with the crankshaft connecting rod to synchronously drive the feeding baffle to reciprocate and open and close, thereby maintaining a stable feeding interval. When the equipment is throwing over a large area at a certain inclination angle, the bait can be discharged faster and more stably under the influence of gravity in the inclined state, ensuring uniform feeding of the rotating throwing mechanism.

[0035] 3. A synchronous movable frame is provided to further cooperate with the synchronous reciprocating mechanism. During the use of the equipment, the synchronous movable frame moves synchronously and reciprocates at the connecting hose with the reciprocating motion of the unloading baffle, so that the material can be effectively loosened when some materials are not flowing smoothly, promoting the flow of bait and reducing blockage. In addition, the synchronous movable frame can also cooperate with the buffer spring to push the crusher body to swing back and forth on the movable guide wheel, which is helpful to further shake the bait and facilitate the screening of the screening plate to ensure the fineness of the bait. The equipment structure is simple and practical;

[0036] 4. A lifting foot is provided for supporting and adjusting the mobile frame. During the use of the equipment, the entire equipment can be flexibly moved to a suitable bait delivery point through the moving wheels and universal wheels of the mobile frame. At the same time, the relative support height of the moving wheels and universal wheels can be adjusted through the lifting foot, thereby changing the overall support angle of the equipment, adjusting the feeding plate angle, and then adjusting the parabola of bait casting, which is convenient for flexible regional delivery adjustment.

The crushing mechanism 2 of this embodiment adopts a paired crushing roller structure to perform crushing operations, which is suitable for rapid crushing of large pieces of hard bait. The interior of the crusher body 1 is divided into a crushing bin 101 and a feeding bin 102 from top to bottom. The crushing mechanism 2 is located inside the crushing bin 101, and a synchronous movable frame 903 is located inside the feeding bin 102 for mixing and mixing materials. The crushing bin 101 at the upper section of the crusher body 1 is used to cooperate with the crushing mechanism 2 to crush the bait.

At the same time, the synchronous movable frame 903 reciprocates between the feeding bin 102 and the connecting hose 12 to facilitate the mixing and discharging of the material and avoid material compaction and blockage. A screening plate 105 is installed between the crushing bin 101 and the discharge bin 102, and a feed port 103 and a discharge port 104 are respectively provided at the upper end of the crushing bin 101 and the lower end of the discharge bin 102, wherein the discharge port 104 is connected to the connecting hose 12.

A certain inclination angle can also facilitate unloading, such as Fig.10Under working conditions, the equipment is tilted backward as a whole, and the parabolic upward movement of the bait can be used for spreading over a wider range. At the same time, since the movable opening of the discharge baffle 902 at the discharge funnel 11 is located at the rear, the material can be dropped more quickly and stably in the tilted state, thereby ensuring stable spreading of the bait over a large range.

A feeding port 401 is provided at the front end of the feeding tray 4, and a side movable baffle 402 is movably provided on the outside of the feeding port 401 for opening and closing adjustment of the feeding port 401.

The side movable baffle 402 is an arc-shaped structure that fits the outer ring of the feeding tray 4 as a whole, and the side movable baffle 402 is symmetrically arranged on the left and right sides of the feeding port 401.

In addition, the synchronous movable frame 903 can also cooperate with the buffer spring 14 to push the grinder body 1 to swing back and forth on the movable guide wheel 6, which helps to further shake the bait.

[0055] Example 2: The main difference between the technical solutions of Example 2 and Example 1 is that the crushing mechanism 2 of this example adopts a cutting knife structure for crushing operations, which is suitable for material processing and crushing such as adding grass as bait in grass carp farming. At the same time, the crushing mechanism 2 and the screening plate 105 are adapted and adjusted, and the cutting surface of the crushing mechanism 2 is close to the screening plate 105 and remains parallel to the screening plate 105, so that the bait accumulated above the screening plate 105 can be fully crushed. At the same time, the synchronous reciprocating mechanism 9 can be further combined to promote the reciprocating movement of the grinder body 1 and the screening plate 105 as a whole, so as to shake the bait for full crushing, avoid crushing blind spots, and fully and efficiently process the bait.
