Description

Technical Field

[0001] The utility model relates to the technical field of feed processing equipment, and particularly relates to a discharging device of a feed mixer. Background Art

[0002] A feed mixer is a device specifically used for mixing various feed components and is widely used in the livestock and aquaculture industries. A feed mixer generally includes a housing, a mixing container, a stirring device, a transmission system, a feed inlet and a feed outlet. Different types and proportions of feed raw materials in the mixing container are mixed together through the rotational movement in the stirring device to meet the nutritional requirements of different livestock and poultry.

[0003] For example, a high-efficiency feed mixer is disclosed in Chinese patent document CN208194177U. The feed mixer includes a horizontal housing with a feed inlet and a feed outlet provided thereon. It adopts two layers of spiral ribbons inside and outside, and the spiral is designed to be reverse spirals inside and outside, left and right. During operation, the inner spiral drives the material near the axis to rotate around the axis, and axially pushes from the inside to both sides. The outer spiral drives the material near the cylinder wall to rotate around the axis, and axially pushes from both sides to the inside. Thus, the material is caused to convect and circulate, shear and mix in the cylinder.

[0004] However, in the actual use process of the above-mentioned feed mixer, the discharging usually adopts the method of spiral rotation and propulsion for discharging, that is, a screw conveyor is used to push the mixed feed out of the feed outlet. This discharging method has the problems of slow discharging and low production efficiency, which easily affects the continuous stirring operation of the feed mixer and also affects the operation progress of the subsequent packaging process. In addition, this discharging method also has the problem of incomplete discharging, resulting in residual materials piled up in the mixing container.

[0005] Although, in the prior art, a drawplate discharging structure is adopted for the horizontal feed mixer for discharging, that is, a baffle is provided at the feed outlet, and a telescopic device is used to drive the baffle to move horizontally to realize the opening and closing of the feed outlet. However, during the opening process of the baffle, due to the pressure exerted by the feed on the baffle, the baffle is prone to jamming, which in turn affects the discharging efficiency. At the same time, when the baffle is in the state of closing the feed outlet, it is difficult to ensure the sealing effect at the edge of the baffle. Summary of the Invention

[0006] The purpose of the utility model is to provide a discharging device for a feed mixer during its use, so as to improve the discharging efficiency of the feed mixer, enhance the sealing performance of the feed outlet, solve the problem of discharging residue, and realize continuous production.

[0007] To achieve the above purpose, the utility model adopts the following scheme:

[0008] An unloading device for a feed mixer, comprising an opening and closing assembly disposed below the unloading port of the feed mixer, and a buffer bin;

[0009] A connecting flange is provided at the top of the buffer bin, the connecting flange is connected to the unloading port of the feed mixer, and a limiting retaining ring is provided on the inner wall of the connecting flange;

[0010] The opening and closing assembly includes a pair of door panels, and a telescopic mechanism for driving the door panels to perform a flipping motion. The rotating shaft of the door panels is installed on the side wall of the buffer bin, the connecting end of the telescopic mechanism is installed on the side wall of the buffer bin, and the telescopic end of the telescopic mechanism is connected to the door panels. The opening and closing assembly has an open state and a closed state;

[0011] When the opening and closing assembly is in the open state, the telescopic end of the telescopic mechanism contracts, and a pair of door panels rotate towards the inside of the buffer bin around the rotating shaft, and the unloading port is communicated with the buffer bin;

[0012] When the opening and closing assembly is in the closed state, the telescopic end of the telescopic mechanism protrudes, and a pair of door panels fit against the limiting retaining ring to form a seal for the unloading port.

[0013] Among them, by driving the telescopic mechanism to switch the opening and closing states of the opening and closing assembly, the opening and closing of the unloading port can be accurately controlled, realizing the rapid unloading of feed. The door panels rotate towards the inside of the buffer bin around the rotating shaft, and under the action of the gravity of the feed, it is convenient for the opening and closing assembly to be opened smoothly, avoiding jamming. The door panels fit against the limiting retaining ring to form an effective seal, preventing the leakage of feed during non-unloading periods. The overall structure of the unloading device is designed compactly and reasonably, occupying a small space, and is convenient for installation and layout. The design of the connecting flange and the limiting retaining ring ensures the stable connection between the unloading port and the buffer bin, improving the overall stability and reliability of the device.

[0014] Preferably, the door panels include a first door panel and a second door panel. Both the first door panel and the second door panel are located between the buffer bin and the unloading port.

In this way, the sealing gasket is used to further improve the sealing performance at the junction of the door panels, ensuring the sealing effect when the opening and closing assembly is in the closed state.

[0015] Preferably, the card slot is provided on the first door panel, and the edge of the second door panel is embedded in the card slot.

[0016] Preferably, a manual butterfly valve is provided at the bottom of the buffer bin.

[0017] Preferably, a pneumatic hammer is arranged on the outer side of the buffer bin, and the pneumatic hammer is installed on the outer wall of the buffer bin. With this arrangement, the pneumatic hammer is used to continuously strike the side wall of the buffer bin, applying a vibration force to the material on the inner wall of the buffer bin. Through continuous knocking and vibration, it prevents the material from adhering and blocking, ensuring the smooth flow of the material.

[0018] Preferably, the longitudinal section of the buffer bin is in the shape of a right trapezoid, and the pneumatic hammer is located on the hypotenuse of the right trapezoid. With this arrangement, the right trapezoid structure can effectively prevent the material from accumulating on the inner wall of the buffer bin, solving the problems of slow loading and incomplete discharging.

The door panel fits against the limit retaining ring to form an effective seal, preventing the leakage of feed during non-discharge periods, improving the sealing performance of the discharge port. At the same time, the buffer bin is in the shape of a right trapezoid, which can effectively prevent the material from accumulating on the inner wall of the buffer bin, solving the problems of slow loading and incomplete discharging.

[0028] The following will describe in detail the specific implementation manners of the present utility model with reference to the accompanying drawings.

[0029] As Figures 1-5 shown, in the embodiment of the present utility model, a discharging device for a feed mixer is proposed, aiming to improve the discharging efficiency of the feed mixer, enhance the sealing performance of the discharging port, and solve the problems of slow loading and discharging residue.

[0030] In the discharging device for a feed mixer proposed in the embodiment of the present utility model, the telescopic mechanism is driven to drive the door panel to open downward, so that the material can be quickly discharged within a short time, improving the discharging efficiency of the feed mixer and leaving no material residue in the mixer. At the same time, after all the materials in the mixer are discharged, the door panel closes, and the mixer can immediately carry out the mixing production of the next batch, realizing continuous production, improving the production efficiency. The door panel fits against the limit retaining ring to form an effective seal, preventing the leakage of feed during non-discharging periods and enhancing the sealing performance of the discharging port.

[0031] As Figure 1 Combined with Figure 2 shown, a discharging device for a feed mixer includes an opening and closing assembly disposed below the discharging port of the feed mixer and a buffer bin 2. Among them, the horizontal feed mixer 1 is taken as an example of the feed mixer.

[0032] As Figure 2 Combined with Figure 3 shown, a connecting flange 3 is provided at the top of the buffer bin 2. The connecting flange 3 is connected to the discharging port of the feed mixer. A limit retaining ring 6 is provided on the inner wall of the connecting flange 3.

[0033] As Figure 3 shown, the opening and closing assembly includes a pair of door panels and a telescopic mechanism 7 for driving the door panels to perform a flipping motion. The rotating shaft of the door panel is installed on the side wall of the buffer bin 2. The connecting end of the telescopic mechanism 7 is installed on the side wall of the buffer bin 2. The telescopic end of the telescopic mechanism 7 is connected to the door panel. The opening and closing assembly has an open state and a closed state.

[0034] When the opening and closing assembly is in the open state, the telescopic end of the telescopic mechanism 7 contracts, and a pair of door panels rotate towards the inside of the buffer bin 2 around the rotating shaft, and the discharging port is communicated with the buffer bin 2. As Figure 3 Combined with Figure 4 shown, when the opening and closing assembly is in the closed state, the telescopic end of the telescopic mechanism 7 protrudes, and a pair of door panels fit against the limit retaining ring 6 to form a seal for the discharging port.

[0035] Among them, the telescopic mechanism 7 is a pneumatic telescopic rod. The cylinder body of the pneumatic telescopic rod is installed on the side wall of the buffer bin 2. The piston rod of the pneumatic telescopic rod is connected to the door panel. For example, each side of the door panel in the opening and closing assembly is correspondingly provided with 3 pneumatic telescopic rods, and the 3 pneumatic telescopic rods are arranged in parallel, further ensuring the support stability of the door panel.

[0036] As Figure 3 shown, the door panel includes a first door panel 4 and a second door panel 5. A pair of door panels are symmetrically arranged along the center line of the discharge port. As Figure 5 shown, both the first door panel 4 and the second door panel 5 are located between the buffer bin 2 and the discharge port. A card slot 10 is provided at the junction of the first door panel 4 and the second door panel 5. A sealing gasket 11 is arranged in the card slot 10. With such a setting, the sealing gasket 11 is used to further improve the sealing performance at the junction of the door panels, ensuring the sealing effect when the opening and closing assembly is in the closed state.

[0037] For example, the card slot 10 is arranged on the first door panel 4, and the edge of the second door panel 5 is embedded in the card slot 10. When the opening and closing assembly is opened, the telescopic mechanism 7 first drives the second door panel 5 to rotate, and then drives the first door panel 4 to rotate, avoiding interference between the first door panel 4 and the second door panel 5. When the clamping assembly is closed, the telescopic mechanism 7 first drives the first door panel 4 to rotate, and then drives the second door panel 5 to rotate.

[0038] As Figure 3 shown, a pneumatic hammer 9 is arranged outside the buffer bin 2. The pneumatic hammer 9 is installed on the outer wall of the buffer bin 2. With such a setting, the pneumatic hammer 9 is used to continuously strike the side wall of the buffer bin 2, applying a vibration force to the materials on the inner wall of the buffer bin 2. Through continuous knocking and vibration, it prevents materials from adhering and blocking, ensuring the smooth flow of materials.

[0039] As Figure 3 shown, the longitudinal section of the buffer bin 2 is in the shape of a right-angled trapezoid, and the pneumatic hammer 9 is located on the hypotenuse of the right-angled trapezoid. With such a setting, the right-angled trapezoid structure can effectively prevent materials from accumulating on the inner wall of the buffer bin 2, solving the problems of slow loading and incomplete discharging. For example, the angle between the hypotenuse and the base is 60 o .

[0040] The above-mentioned pneumatic telescopic rod and the pneumatic hammer 9 are both driven by compressed air and controlled through a conventional gas pipeline structure.

[0041] As Figure 2 shown, a manual butterfly valve 8 is arranged at the bottom of the buffer bin 2. With such a setting, the manual butterfly valve 8 is used to control the discharging amount, which is simple and easy to operate and can well control the loading speed, helping to solve the problem of material overflowing from the packaging bag due to relatively fast discharging.

[0042] When the discharging device of a feed mixer proposed in the embodiment of the present utility model is in use, first, connect the buffer bin 2 to the discharging port of the feed mixer, ensure that the connecting flange 3 and the discharging port are tightly fitted, and check whether the limit retaining ring 6 on the inner wall of the flange is intact. Ensure that the telescopic mechanism 7, the door panel and the rotating shaft are correctly installed on the side wall of the buffer bin 2, and all components are free of looseness or damage.

[0043] Start the feed mixer to complete the mixing operation. After the mixing is completed, prepare for the discharging operation. At this time, ensure that the opening and closing assembly is in the closed state, that is, the telescopic end of the telescopic mechanism 7 protrudes, so that a pair of door panels fit against the limit retaining ring 6 to form a closed state, preventing the mixed feed from flowing out in advance.

[0044] When it is necessary to start discharging, operate the control system to make the opening and closing assembly in the open state. At this time, the telescopic end of the telescopic mechanism 7 contracts, driving a pair of door panels to rotate towards the inside of the buffer bin 2 around the rotating shaft, so that the discharging port is communicated with the buffer bin 2. The buffer bin 2 receives the mixed feed flowing out of the discharging port and reduces the impact force of the feed through its buffering effect.

[0045] During the discharging process, monitor the feed flow rate at any time to ensure smooth discharging without blockage. The working state of the telescopic mechanism 7 can be adjusted as needed to control the opening degree of the discharging port so that the discharging flow rate meets the production requirements. Ensure that there is no leakage during the discharging process. If any abnormal situation is found, stop the operation immediately for inspection and handling.

[0046] When the required amount of feed has been discharged or it is necessary to pause the discharging, operate the control system to make the opening and closing assembly in the closed state. At this time, the telescopic end of the telescopic mechanism 7 protrudes, so that a pair of door panels fit against the limit retaining ring 6 to close the discharging port. After ensuring that the discharging port is completely closed, the mixing operation of the mixer can be continued.

[0047] By driving the telescopic mechanism 7 to switch the opening state and the closing state of the opening and closing assembly, the discharging device of the feed mixer proposed in the embodiment of the present utility model can accurately control the opening and closing of the discharging port, realizing rapid discharging of the feed. The door panel rotates towards the inside of the buffer bin 2 around the rotating shaft, and under the action of the gravity of the feed, it is convenient for the opening and closing assembly to be opened smoothly, avoiding jamming. The door panel fits against the limit retaining ring 6 to form an effective seal, preventing the leakage of feed during non-discharging periods. The overall structural design of the discharging device is compact and reasonable, occupying a small space and being convenient for installation and layout. The designs of the connecting flange 3 and the limit retaining ring 6 ensure the stable connection between the discharging port and the buffer bin 2, improving the overall stability and reliability of the device.

[0048] The present utility model is not limited to the specific technical solutions described in the above embodiments. In addition to the above embodiments, the present utility model may also have other implementation manners. For those skilled in the art, any technical solutions formed by making any modifications, equivalent replacements, improvements, etc. within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
