Description

Technical Field

[0001] This utility model relates to the field of hopper cleaning technology, specifically a hopper cleaning device for dairy farming. Background Technology

[0002] In dairy farming, the hopper is the core equipment for feed storage and feeding, and its cleanliness directly affects the health of dairy cows. In existing technologies, such as the hopper cleaning device disclosed in authorization announcement number CN221537534U, a rotating brush driven by a motor is used to mechanically scrape and clean the inner wall of the hopper. Although this improves the cleaning efficiency, the following technical bottlenecks still exist.

[0003] The aforementioned device achieves the function of cleaning the hopper. However, in actual use, the feed in the hopper relies on gravity to flow out. When the feed has high moisture content or contains fibrous material, it is easy to form bridging blockages at the bottom of the conical hopper, resulting in poor or even interrupted discharge, which seriously affects the feeding efficiency. At the same time, the device cannot clean the discharge pipe, and the feed accumulates in the discharge pipe. Over a long period of time, it will ferment and deteriorate, increasing the risk of bacterial growth. Utility Model Content

[0004] The purpose of this utility model is to provide a hopper cleaning device for dairy farming. This device uses a combination of large and small spiral blades and a stepped design to break up arches and prevent clogging. Combined with a full-path self-cleaning structure and a double scraping design, it reduces residue, improves cleaning efficiency, and significantly enhances the hopper's discharge efficiency and cleaning effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feed hopper cleaning device for dairy farming, comprising a feed hopper with an openable and closable cover at the top, a conical hopper connected to the bottom of the feed hopper, a discharge pipe at the center of the bottom of the conical hopper, and a horizontally pull-out baffle assembly at the bottom of the discharge pipe; a rotating shaft driven by a drive device is vertically inserted inside the feed hopper, the lower end of the rotating shaft extends into the discharge pipe and is coaxially provided with small spiral blades, the outer diameter of the small spiral blades being clearance-fitted with the inner wall of the discharge pipe; the shaft section of the rotating shaft located inside the conical hopper is provided with large spiral blades, the outer diameter of the large spiral blades decreasing in a stepped manner from top to bottom; two radial scrapers are symmetrically fixed to the rotating shaft inside the conical hopper, the outer edge of the scrapers being provided with a wear-resistant layer that slides in contact with the inner wall of the conical hopper; an axially sliding annular scraper sleeve is fitted on the top of the rotating shaft, the outer edge of the annular scraper sleeve contacting and fitting with the inner wall of the feed hopper, and the annular scraper sleeve is connected to the cover via a first lifting device.

[0006] To enhance sealing reliability and prevent feed leakage, the preferred embodiment of the dairy cow hopper cleaning device of this utility model includes a feed baffle assembly comprising horizontal slide rails symmetrically arranged on both sides of the discharge pipe, an L-shaped sealing slide plate slidably arranged between the two horizontal slide rails, and a telescopic device for driving the sealing slide plate to slide linearly. The telescopic device is horizontally installed on the side wall of the discharge pipe, and the sealing slide plate is in contact with the bottom plane of the discharge pipe.

[0007] In order to provide a stable power source and ensure controllable speed, the preferred drive device for the dairy cattle hopper cleaning device of this utility model is a geared motor located on the top of the cover, and the output shaft of the geared motor is coaxially connected to the rotating shaft through a coupling.

[0008] In order to achieve precise lifting and lowering control of the annular scraper sleeve, the first lifting device of the dairy cow hopper cleaning device of this utility model is preferably an electric push rod, the fixed end of which is connected to the top of the cover, and the movable end passes through the cover and is fixedly connected to the annular scraper sleeve.

[0009] In order to improve the wear resistance of key components and extend their service life, the wear-resistant layer of the scraper outer edge is preferably made of polytetrafluoroethylene strip, and the surface of the large spiral blade is covered with a polyurethane elastic layer.

[0010] In order to achieve stable opening and closing of the cover's heavy-weight structure, as a preferred embodiment of the dairy cow hopper cleaning device of this utility model, two sets of second lifting devices are symmetrically arranged on the outer wall of the hopper. The second lifting device is a hydraulic cylinder and the cylinder body is fixedly connected to the hopper. The piston rod is connected to the bottom of the cover, and the top of the cover is provided with a feeding port.

[0011] To enhance the mobility and positioning stability of the equipment, in a preferred embodiment of the dairy cow hopper cleaning device of this utility model, the bottom of the conical hopper is fixedly connected to a support frame, and the bottom of the support frame is provided with casters with a braking mechanism.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model solves the problem of clogging in high-humidity or fibrous feed by using a stepped variable diameter large spiral blade and a small spiral blade, thereby improving the discharge efficiency. The small spiral blade, which extends to the discharge pipe through the rotating shaft, enables the self-cleaning of the discharge pipe.

[0014] 2. This utility model achieves full-path cleaning of the storage hopper, conical hopper, and discharge pipe through a rotating scraper and lifting scraper sleeve, reducing the risk of bacterial growth. The sealed sliding plate design ensures zero leakage at the discharge port, reducing feed waste.

[0020] Please see Figures 1 to 4 A feed hopper cleaning device for dairy farming includes a feed hopper 2 with an openable and closable cover 1 at the top, a conical hopper 3 connected to the bottom of the feed hopper 2, a discharge pipe 4 located at the center of the bottom of the conical hopper 3, and a horizontally pull-out baffle assembly 5 at the bottom of the discharge pipe 4; a rotating shaft 7 driven by a drive device 6 is vertically inserted inside the feed hopper 2, the lower end of the rotating shaft 7 extends into the discharge pipe 4 and is coaxially provided with small spiral blades 8, the outer diameter of the small spiral blades 8 being in clearance fit with the inner wall of the discharge pipe 4; the rotating shaft 7... The shaft 7 located inside the conical hopper 3 has a large spiral blade 9, the outer diameter of which decreases in a stepped manner from top to bottom; the rotating shaft 7 has two radial scrapers 10 symmetrically fixed inside the conical hopper 3, and the outer edge of the scraper 10 has a wear-resistant layer 11 that slides in contact with the inner wall of the conical hopper 3; the top of the rotating shaft 7 is fitted with an axially sliding annular scraper sleeve 12, the outer edge of which contacts and engages with the inner wall of the storage hopper 2, and the annular scraper sleeve 12 is connected to the cover 1 through the first lifting device 13.

[0021] In this embodiment: the drive device 6 drives the rotating shaft 7 to rotate, and the large and small spiral blades 8 work together. The large spiral blade 9 rotates in the conical hopper 3, pushing the feed downward, while the small spiral blade 8 forces the feed to be transported in the discharge pipe 4 to prevent blockage. The scraper 10 rotates with the rotating shaft 7 to scrape off the feed residue on the inner wall of the conical hopper 3. The annular scraper sleeve 12 moves up and down through the first lifting device 13 to clean the inner wall of the storage hopper 2. The baffle cover assembly 5 is controlled by the telescopic device 16 to slide horizontally, realizing the sealing and opening and closing of the discharge pipe 4. The polyurethane elastic layer 17 controls the opening and closing of the cover 1, which is convenient for equipment maintenance.

[0022] As a technical optimization of this utility model, the baffle cover assembly 5 includes horizontal slide rails 14 symmetrically arranged on both sides of the discharge pipe 4, an L-shaped sealing slide plate 15 slidably arranged between the two horizontal slide rails 14, and a telescopic device 16 for driving the sealing slide plate 15 to slide linearly. The telescopic device 16 is horizontally installed on the side wall of the discharge pipe 4, and the sealing slide plate 15 is in contact with the bottom plane of the discharge pipe 4.

[0023] In this embodiment, the telescopic device 16 is preferably an electric telescopic rod or a hydraulic cylinder. Through the telescopic device 16, the sealing slide plate 15 can achieve the function of automatic sliding, which makes it easy to automatically open or close the discharge pipe 4, enhance the sealing reliability, prevent feed leakage, and avoid feed from getting damp and clumping.

[0024] As a technical optimization of this utility model, the driving device 6 is a geared motor located on the top of the cover 1, and the output shaft of the geared motor is coaxially connected to the rotating shaft 7 through a coupling.

[0025] In this embodiment: the drive device 6 provides a stable power source, ensuring that the rotation speed of the rotating shaft 7 is controllable, which can easily improve the efficiency of material conveying and prevent the discharge pipe 4 from being blocked.

[0026] As a technical optimization of this utility model, the first lifting device 13 is an electric push rod, whose fixed end is connected to the top of the cover 1, and whose movable end passes through the cover 1 and is fixedly connected to the annular scraper sleeve 12.

[0027] In this embodiment: the annular scraper sleeve 12 slides axially within the storage hopper 2 via the first lifting device 13, which can clean the inner wall of the storage hopper 2 and adapt to different material heights.

[0028] As a technical optimization of this utility model, the wear-resistant layer 11 on the outer edge of the scraper 10 is a polytetrafluoroethylene strip, and the surface of the large spiral blade 9 is covered with a polyurethane elastic layer 17.

[0029] In this embodiment, both the polytetrafluoroethylene strip and the polyurethane elastic layer 17 reduce the friction coefficient of the scraper 10 and the large spiral blade 9.

[0030] As a technical optimization of this utility model, two sets of second lifting devices 18 are symmetrically provided on the outer wall of the storage hopper 2. The second lifting device 18 is a hydraulic cylinder and the cylinder body is fixedly connected to the storage hopper 2. The piston rod is connected to the bottom of the cover body 1, and the top of the cover body 1 is provided with a feeding port 19.

[0031] In this embodiment, the cover 1 can be automatically opened by the second lifting device 18, reducing the intensity of manual operation.

[0032] As a technical optimization of this utility model, a support frame 20 is fixedly connected to the bottom of the conical bucket 3, and a universal wheel 21 with a braking mechanism is provided at the bottom of the support frame 20.

[0033] In this embodiment: the support frame 20 and the casters 21 support and move the conical bucket 3, and the braking mechanism on the casters 21 ensures operational safety, and the casters 21 with brakes are adaptable to different feeding scenarios; it should be noted that the braking mechanism is existing technology.

[0034] Working principle and usage process of this utility model:

[0035] Using the casters 21 with brakes at the bottom, the hopper cleaning device is moved to a suitable working position, and then the brakes are depressed to stabilize the device. Feed can be stored in the storage hopper 2 through the feeding port 19. Since the bottom of the storage hopper 2 is connected to a conical hopper 3, the feed will naturally slide towards the conical hopper 3 and the discharge pipe 4 under gravity. During discharge, the drive device 6 (reduction motor) is activated, and its output shaft drives the rotating shaft 7 to rotate via a coupling. The small spiral blades 8 at the lower end of the rotating shaft 7 rotate inside the discharge pipe 4, breaking up clumps of feed and simultaneously pushing the feed downwards to prevent blockage of the discharge pipe 4. The outer diameter of the spiral blade 8 is fitted with the inner wall of the discharge pipe 4 with a clearance, which can effectively transport feed and avoid excessive friction. The large spiral blade 9 located inside the conical hopper 3 on the rotating shaft 7 also rotates. The outer diameter of the large spiral blade 9 decreases in a stepped manner from top to bottom. This design can make the feed flow more evenly downward in the conical hopper 3 and avoid local accumulation that could cause blockage. The two radial scrapers 10 inside the conical hopper 3 on the rotating shaft 7 rotate with the rotating shaft 7. The wear-resistant layer 11 (polytetrafluoroethylene strip) on the outer edge of the scraper 10 slides in contact with the inner wall of the conical hopper 3, scraping off the feed adhering to the inner wall of the conical hopper 3, further promoting the flow of feed.

[0036] During cleaning: Activate the first lifting device 13 (electric push rod), whose movable end drives the annular scraper sleeve 12 to slide axially on the rotating shaft 7; the outer edge of the annular scraper sleeve 12 contacts and engages with the inner wall of the storage hopper 2, scraping off the feed adhering to the inner wall of the storage hopper 2 during the up-and-down sliding process, ensuring that the inner wall of the storage hopper 2 is clean. After the feed supply is completed, activate the telescopic device 16 again, driving the sealing slide plate 15 to slide in the opposite direction, so that it fits against the bottom plane of the discharge pipe 4, closing the discharge port and preventing feed from continuing to flow out; and activate the drive device 6 to continuously drive the rotating shaft 7 to rotate for a period of time, allowing the small spiral blade 8, the large spiral blade 9 and the scraper 10 to continue working, discharging as much remaining feed as possible, and cleaning the discharge pipe 4 and the inner wall of the conical hopper 3.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
