It mainly consists of nutrients such as protein, fat, carbohydrates, inorganic salts, vitamins and trace elements, as well as inductive ingredients that promote shrimp feeding. During the feed production and bagging process, different particles need to be poured into the bag in sequence, or mixed separately in proportion before bagging; and the granular material filling machine is a common filling equipment, and its main function is to fill granular materials such as mixed feed, compound fertilizer, etc.

[0003] Existing technologies, such as the fully automatic filling machine disclosed in the utility model patent publication number CN221394154U, include: a filling hopper, a stirring mechanism for stirring the material in the filling hopper, and a discharge port; the stirring mechanism is composed of a forward and reverse motor, a stirring paddle for stirring the material horizontally, and a stirring screw for stirring the material vertically; the forward and reverse motor drives the stirring paddle and stirring screw to be connected in sequence. The fully automatic filling machine of the utility model is connected synchronously by the stirring paddle and the stirring screw. When the forward and reverse motor rotates forward, the stirring paddle stirs the material horizontally, and the stirring screw turns the material upward, thereby stirring the material more evenly; when the motor reverses, the stirring blade stirs the material in the upper hopper, and the stirring screw discharges the material evenly, thereby preventing accumulation and uneven discharge at the discharge port.

[0004] The filling machine can achieve uniform feeding, but it is not easy to accurately control the weight of the feeding during the feeding process; the connecting parts are built-in and easily affected by the feed, and are not easy to clean.

[0011] Furthermore, the second pulley is rotatably mounted on the two discharge pipes respectively, and the discharge pipe is divided into two sections and connected by the second pulley.

[0012] Furthermore, a solenoid valve is installed at the lower end of the discharge pipe.

[0026] like Figures 1 to 5 As shown, the weighing filling mechanism of the utility model comprises: a bracket 1, a feeding mechanism 4 for uniform feeding, and an adjusting mechanism 6 for improving filling efficiency.

[0027] A mounting frame 2 is fixedly mounted on the bracket 1, a filling hopper 7 is fixedly mounted on the mounting frame 2, and a stirring mechanism 3 is installed in the filling hopper 7. The stirring mechanism 3 includes: a stirring shaft 32, a stirring paddle 33, and a rotating shaft of a first motor 31 fixedly connected to the stirring shaft 32; the stirring paddles 33 are evenly mounted on the stirring shaft 32, and the length of the stirring paddle 33 located at the bottom is shorter than the length of the stirring paddle 33 located at the top; the stirring shaft 32 passes through the inner wall of the filling hopper 7 and is sealed by a sealing ring.

[0028] The discharge mechanism 4 includes: a discharge pipe 42, a spiral blade 41, and a connecting member 5 that drives the spiral blade 41 to rotate; the discharge pipe 42 is installed at the bottom of the filling bucket 7, and the spiral blade 41 is located in the discharge pipe 42 and extends into the interior of the filling bucket 7; the edge of the spiral blade 41 is in active contact with the inner wall of the discharge pipe 42; a solenoid valve 43 is installed at the lower end of the discharge pipe 42; the connecting member 5 includes: a first pulley 51, a second pulley 52, and a transmission belt 53; the second pulley 52 is rotatably installed on the two discharge pipes 42 respectively, and the discharge pipe 42 is divided into two sections and is connected by the second pulley 52; bearings 54 are fixedly installed at the upper and lower ends of the second pulley 52, and the ends of the two sections of the discharge pipe 42 are in contact with the bearings 54, and sealing rings are fixedly installed at the ends of the two sections of the discharge pipe 42 that are in contact with the bearings 54 , to prevent leakage; the two second pulleys 52 have different heights, so that the positions of the two transmission belts 53 are staggered; the spiral blade 41 is fixedly mounted on the inner wall of the second pulley 52, and the spiral blade 41 is driven to rotate by the second pulley 52; the spiral blade 41 is fixedly mounted on the central shaft, and the central shaft is located on the central axis of the discharge pipe 42; a fixing frame 44 is fixedly mounted on the lower end of the inner wall of the discharge pipe 42, and a central shaft is rotatably mounted in the fixing frame 44, and the central shaft has two support points, which supports the spiral blade 41 through the central shaft. At the same time, the edge of the spiral blade 41 is in sliding contact with the inner wall of the discharge pipe 42, reducing the shaking amplitude of the central shaft during rotation, thereby making the spiral blade 41 more stable during rotation; the first pulley 51 is fixedly mounted on the stirring shaft 32, and drives the two second pulleys 52 to rotate through the transmission belt 53.

[0029] By placing the connecting member 5 outside, direct contact between the connecting member 5 and the feed is avoided, which affects the use of the connecting member 5 and also prevents the connecting member 5 from affecting the cleaning inside the device; when the rotating shaft of the first motor 31 rotates forward, the first pulley 51 is driven to rotate by the stirring shaft 32, and the first pulley 51 drives the second pulley 52 to rotate through the transmission belt 53, and the second pulley 52 rotates between the two sections of the feeding pipe 42 through the bearing 54, and the second pulley 52 drives the spiral blade 41 downward to facilitate uniform feeding and avoid blockage; when the rotating shaft of the first motor 31 is reversed, the spiral blade 41 is pushed upward to stir the feed together with the stirring paddle 33 to mix the feed evenly.

[0030] The adjusting mechanism 6 includes: a moving plate 61, a positioning cylinder 62, and an adjusting member for adjusting the moving plate 61; the adjusting member is composed of a spur rack 65, a gear 66 meshing with the spur rack 65, and a second motor 64 that drives the gear 66 to rotate; the two contacting moving plates 61 are fixedly connected to the moving frame, and the spur rack 65 is fixedly installed on the moving frame; a weighing device 63 aligned with the discharge pipe 42 is installed on the bracket 1.

[0031] The weight of the filling is measured by weighing the weighing device 63. When filling with multiple filling ports, when the filling of the multiple filling ports is completed, the rotating shaft of the first motor 31 is reversed, so that the spiral blade 41 is pushed upward and the feeding is stopped. During the feeding process, the electromagnetic valve 43 is used to seal the feeding pipe 42 to reduce the error of the weight of the filled feed; a packaging bag is placed on the positioning cylinder 62, and the rotating shaft of the second motor 64 rotates forward. The gear 66 drives the moving frame to move through the spur rack 65, and the moving frame drives the moving plate 61 to move so that the positioning cylinder 62 is aligned with the weighing device 63. After the filling is completed, the rotating shaft of the second motor 64 is reversed, so that the moving plate 61 moves in the opposite direction until the positioning cylinder 62 on the other moving plate 61 is aligned with the weighing device 63. The packaging bag on the moving plate 61 is suspended in the air and automatically falls off from the positioning cylinder 62, thereby improving the filling efficiency.

[0032] Working principle:

[0033] Feed raw materials are added to the filling hopper 7, and the first motor 31 is started. The rotating shaft of the first motor 31 reverses and drives the stirring shaft 32 to rotate. The stirring shaft 32 drives the spiral blade 41 to rotate and propel upward through the connecting member 5. The stirring shaft 32 drives the stirring paddle 33 to rotate, and the stirring paddle 33 and the spiral blade 41 stir the feed;

[0034] Put a packaging bag on the positioning cylinder 62, start the second motor 64, the rotating shaft of the second motor 64 rotates forward, the gear 66 drives the moving frame to move through the spur rack 65, and the moving frame drives the moving plate 61 to move, so that the positioning cylinder 62 is aligned with the weighing device 63;

[0035] The shaft of the first motor 31 rotates forward, driving the first pulley 51 to rotate through the stirring shaft 32. The first pulley 51 drives the second pulley 52 to rotate through the transmission belt 53. The second pulley 52 rotates between the two sections of the discharge pipe 42 through the bearing 54. The second pulley 52 drives the spiral blade 41 downward to facilitate uniform discharge and avoid blockage. The feed falls into the packaging bag. When the weight of the feed in the packaging bag reaches the requirement, the corresponding solenoid valve 43 is closed, and the other discharge pipes 42 are used normally, reducing the filling error of different filling ports;

[0036] After filling is completed, the rotating shaft of the first motor 31 is reversed, so that the spiral blade 41 is pushed upward and the material feeding is stopped. The rotating shaft of the second motor 64 is reversed, so that the movable plate 61 moves in the opposite direction until the positioning cylinder 62 on the other movable plate 61 is aligned with the weighing device 63. The packaging bag on the movable plate 61 is suspended in the air and automatically falls off the positioning cylinder 62 and is filled through multiple filling ports to improve the filling efficiency.
