Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of feed spreading equipment, and particularly to a large-particle feed spreader. Background Art
[0002] In the breeding industry, the use of feed spreaders is of great significance for improving feed utilization rate, reducing breeding costs, and enhancing breeding efficiency. However, in the actual use process of traditional feed spreaders, there are some problems, such as unsmooth feed feeding, uneven spreading, limited spreading distance, etc. These problems not only affect the use effect of the feed but also increase the workload of breeders. Summary of the Invention
[0003] The present invention relates to a large-particle feed spreader, which sprays air into the spreading pipe through a spray pipe. The blower generates wind under the drive of a servo motor and sends the wind into a connecting air pipe through an air outlet pipe. The connecting air pipe sends the wind into the inner cavity of a spreading spray air box respectively, and sprays the wind into the corresponding spreading pipe through an independent spray pipe. The spray pipe sprays wind towards the mouth of the spreading pipe along the direction of the air flow guiding groove, increasing the spreading distance and range of the feed. When the feed is lifted by a spreading fan, affected by the inclined structure of the spreading pipe which is inclined obliquely upward and outward, the feed is guided to be spread in a specific direction. At the same time, the spreading spray air box sprays wind into the spreading pipe through the spray pipe, further pushing the feed to be spread to a farther place. The spread feed can cover a wider area under the combined action of wind force and the spreading fan, realizing uniform spreading, significantly increasing the spreading distance of the feed, and enabling the feed to cover a farther area.
[0004] The present invention provides a large-particle feed spreader, which specifically includes: a support frame, a spreading box, a driving and blowing frame, a support and fixing frame, a feed hopper, a servo motor, a driving shaft rod, and a spreading spray air box; the upper end of the support frame is fixedly installed with the spreading box; the upper end of the spreading box is fixedly butted with the feed hopper; a support and fixing frame is arranged between the feed hopper and the spreading box; a servo motor is arranged in the middle of the lower end of the spreading box; the driving and blowing frame is fixedly installed on the support frame below the spreading box; a driving shaft rod is rotatably installed between the middle parts of the inner cavities of the feed hopper and the spreading box, and the lower end of the driving shaft rod passes through the spreading box and is fixedly connected with the rotating shaft of the servo motor through a coupling; the spreading spray air box is annularly distributed at the lower end position of the outer wall of the spreading box.
[0005] Optionally, the spreading box is a six-sided truncated cone-shaped structure with a narrower upper part and a wider lower part. At the positions near the lower ends of the six side walls of the spreading box, spreading pipes are respectively vertically connected. The spreading pipes are inclined obliquely upward and outward, and the inner ends of the spreading pipes are connected with the bottom of the inner cavity of the spreading box; A central position at the bottom of the inner cavity of the spreading pipe is provided with an air flow guiding groove extending towards the mouth of the pipe.
[0006] Optionally, a blower is fixedly installed on the driving air blower frame. The middle part of the lower end of the blower is the air inlet, and one side of the blower is the air outlet pipe. The air outlet pipe is arranged vertically upward. The upper end of the rotating shaft on the air blower wheel in the blower cavity is rotationally connected to the rotating shaft of the servo motor through a belt.
[0007] Optionally, the support fixing frame is in a "rice" - shaped structure. At the upper ends of the six corners of the support fixing frame, upper support rods are respectively vertically fixed upward. The upper ends of the upper support rods are fixedly connected to the outer wall of the feed hopper. A controller is fixedly installed on the outer wall of one of the upper support rods. At the lower ends of the six corners of the support fixing frame, lower support rods are respectively vertically fixed downward. The lower ends of the lower support rods are fixedly connected to the upper ends of the corresponding spreading pipes.
[0008] Optionally, the feed hopper is in a funnel - shaped structure with a wider upper part and a narrower lower part. A wind speed and wind direction detector is provided at the upper end of the feed hopper.
[0009] Optionally, at the position corresponding to the bottom of the spreading box cavity of the driving shaft rod, a spreading fan is fixedly installed. The spreading fan is in a fan - shaped structure composed of six blade plates. The bottom of the spreading fan is tangent to the bottom of the spreading box cavity. The middle part of the spreading fan is in a conical structure with a narrower upper part and a wider lower part; On the driving shaft rod at the upper end of the spreading fan, a spiral feeding auger is fixedly installed. The upper half of the feeding auger is built in the feed hopper. The ring edge of the feeding auger is tangent to the inner cavity side wall at the connection between the feed hopper and the spreading box; At the uppermost end of the driving shaft rod, an upper - narrow material - dividing cone is fixedly installed. Six vertical dial rods are annularly distributed on the conical surface of the material - dividing cone. The end of the dial rod is fixedly connected with a spherical ball head.
[0010] Optionally, at the position corresponding to the spreading pipe on the spreading and spraying air box, a spray pipe is connected. The spray pipe extends to the bottom of the spreading pipe cavity and faces the direction of the spreading pipe nozzle along the air flow guiding groove; One end of the spreading and spraying air box is communicated with six connecting air pipes. The other ends of the connecting air pipes are communicated with the upper end of the air outlet pipe. The ends of the six connecting air pipes connected to the inner cavity of the spreading and spraying air box respectively extend into the inner cavity of the spreading and spraying air box and are communicated with independent spray pipes.
[0011] The present invention provides a large - particle feed spreader, which has the following beneficial effects: 1. In the present invention, the design of the feed hopper with a wider upper part and a narrower lower part enables the feed to flow downward naturally and smoothly, reducing blockage. The settings of the narrower upper distribution cone and the annular distribution rods ensure the uniform distribution of the feed within the inner cavity of the spreading box. The feed is evenly distributed to multiple areas within the inner cavity of the spreading box after being agitated by the annular distribution rods of the narrower upper distribution cone, ensuring the uniformity of feed distribution. At the same time, during the rotation of the rods and the ball heads following the drive shaft rod, while agitating and loosening the feed, it can also prevent the feed from sticking to the wall and bridging in the feed hopper, thus ensuring the feed discharging efficiency, avoiding local accumulation. The rotational agitation of the rods and the ball heads effectively prevents the phenomena of the feed sticking to the wall and bridging in the feed hopper, improving the discharging efficiency.
[0012] 2. The six - blade structure of the spreading fan in the present invention ensures that the feed can be evenly spread in all directions, with a wide coverage range. The tangential design of the spreading fan and the bottom of the inner cavity of the spreading box enables the feed to be effectively lifted from the bottom, further expanding the spreading range.
[0013] 3. In the present invention, the coordinated use of the blower and the spreading jet air box sprays air into the spreading pipe through the spray pipe. The blower generates wind under the drive of the servo motor and sends the wind into the connecting air pipe through the air outlet pipe. The connecting air pipe distributes the wind into the inner cavity of the spreading jet air box respectively and sprays the wind into the corresponding spreading pipes through independent spray pipes. The spray pipes spray the wind towards the nozzle direction of the spreading pipes along the direction of the air flow guiding groove, increasing the throwing distance and range of the feed. When the feed is lifted by the spreading fan, affected by the obliquely outward and upward inclined structure of the spreading pipe, the feed is guided to be thrown in a specific direction. At the same time, the spreading jet air box sprays air into the spreading pipes through the spray pipes, further pushing the feed to be thrown to a farther place. The thrown feed, under the combined action of the wind force and the spreading fan, can cover a wider area, achieving uniform spreading, significantly increasing the throwing distance of the feed, and enabling the feed to cover a farther area.
[0014] 4. The obliquely outward and upward inclined structure of the spreading pipe in the present invention can adjust the throwing direction as needed to achieve precise spreading in a specific area.
[0015] 5. In the present invention, the servo motor drives the spreading fan and the blower simultaneously, realizing the synchronous operation of feed spreading and wind force assistance, greatly improving the spreading efficiency.
[0016] 6. In the present invention, a wind speed and direction detector is provided at the upper end of the feed hopper. Since the feed hopper has a funnel-shaped structure that is wider at the top and narrower at the bottom, the feed can flow smoothly downward. The wind speed and direction detector can detect the wind force and transmit the information to the controller for processing. The controller is electrically connected to the servo motor. When the wind force is large, the rotational speed of the servo motor increases, and the rotational speeds of the spreading fan and the blower increase synchronously. As a result, the feed can obtain a greater spreading force when passing through the spreading pipe, so as to ensure the spreading area even when the wind force is large.

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.
[0022] Embodiment 1: Please refer to Figures 1 to 8 : The present invention provides a large-particle feed spreader, including: a support frame 1, a spreading box 2, a driving and blowing frame 3, a support and fixing frame 4, a feed hopper 5, a servo motor 6, a drive shaft rod 7 and a spreading and spraying air box 8; the upper end of the support frame 1 is fixedly installed with the spreading box 2; the upper end of the spreading box 2 is fixedly butted with the feed hopper 5; a support and fixing frame 4 is provided between the feed hopper 5 and the spreading box 2; a servo motor 6 is provided in the middle of the lower end of the spreading box 2; a driving and blowing frame 3 is fixedly installed on the support frame 1 below the spreading box 2; a drive shaft rod 7 is rotatably installed between the middle parts of the inner cavities of the feed hopper 5 and the spreading box 2, and the lower end of the drive shaft rod 7 passes through the spreading box 2 and is fixedly connected to the rotating shaft of the servo motor 6 through a coupling; the spreading and spraying air boxes 8 are annularly distributed at the lower end position of the outer wall of the spreading box 2.
[0023] Among them, the spreading box 2 has a six-sided frustum-shaped structure that is narrower at the top and wider at the bottom. At the positions near the lower ends of the six side walls of the spreading box 2, spreading pipes 201 are respectively vertically connected. The spreading pipes 201 are inclined obliquely upward and outward, and the inner ends of the spreading pipes 201 are connected to the bottom of the inner cavity of the spreading box 2. An air flow guiding groove 202 is formed at the center of the bottom of the inner cavity of the spreading pipe 201 and extends towards the pipe orifice.
[0024] Among them, a blower 301 is fixedly installed on the driving and blowing frame 3. The middle part of the lower end of the blower 301 is an air inlet 302, and one side of the blower 301 is an air outlet pipe 303. The air outlet pipe 303 is vertically arranged upward. The upper end of the rotating shaft on the air blowing wheel in the inner cavity of the blower 301 is rotationally connected to the rotating shaft of the servo motor 6 through a belt 304.
[0025] Among them, the supporting and fixing frame 4 is a "M"-shaped structure, and upper support rods 401 are respectively fixed vertically upward at the upper ends of the six corners of the supporting and fixing frame 4, and the upper ends of the upper support rods 401 are fixedly connected to the outer wall of the feed hopper 5. A controller 403 is fixed on the outer wall of one of the upper support rods 401, and lower support rods 402 are respectively fixed vertically downward at the lower ends of the six corners of the supporting and fixing frame 4, and the lower ends of the lower support rods 402 are fixedly connected to the corresponding upper ends of the throwing pipes 201.
[0026] Among them, the feed hopper 5 is a funnel-shaped structure that is wide at the top and narrow at the bottom. A wind speed and direction detector 501 is provided at the upper end of the feed hopper 5. Since the feed hopper 5 is a funnel-shaped structure that is wide at the top and narrow at the bottom, the feed can flow smoothly downward, and the wind speed and direction detector 501 can detect the wind force and transmit the information to the controller 403 for processing. The controller 403 is electrically connected to the servo motor 6. When the wind force is strong, the speed of the servo motor 6 increases, and the speeds of the scattering fan 701 and the blower 301 increase synchronously, so that the feed can obtain a greater scattering force when passing through the scattering pipe 201, so that the scattering area can be guaranteed even when the wind force is strong.
[0027] Among them, a scattering fan 701 is fixedly installed at the position of the driving shaft 7 corresponding to the bottom of the inner cavity of the scattering box 2. The scattering fan 701 is a fan-shaped structure composed of six blades. The bottom of the scattering fan 701 is tangent to the bottom of the inner cavity of the scattering box 2. The middle part of the scattering fan 701 is a conical structure with a narrow top and a wide bottom. The servo motor 6 drives the driving shaft 7 to rotate, thereby driving the scattering fan 701 to rotate. The bottom of the scattering fan 701 is tangent to the bottom of the inner cavity of the scattering box 2, which can effectively throw the feed from the bottom. The six-blade structure of the scattering fan 701 can evenly scatter the feed in all directions, ensuring the uniformity and range of feed scattering; A spiral feeding cage 702 is fixedly provided on the driving shaft 7 at the upper end of the spreading fan 701. The upper half of the feeding cage 702 is built into the feed hopper 5. The ring edge of the feeding cage 702 is tangent to the side wall of the inner cavity where the feed hopper 5 and the spreading box 2 are connected. The feed is evenly distributed to multiple areas of the inner cavity of the spreading box 2 by the movement of the annular distribution lever 704 of the upper narrow dividing cone 703, ensuring the uniformity of feed distribution. At the same time, the lever 704 and the ball head 705 can stir the feed and loose feed while avoiding the feed from hanging on the wall and bridging in the feed hopper 5 during the process of following the rotation of the driving shaft 7, thereby ensuring the feed feeding efficiency. An upper narrow material distribution cone 703 is fixedly provided at the uppermost end of the driving shaft 7, and six vertical levers 704 are distributed in a ring on the conical surface of the material distribution cone 703. A spherical ball head 705 is fixedly connected to the end of the lever 704. The unloading cage 702 rotates under the drive of the driving shaft 7, further promoting the downward flow of feed and preventing the feed from being blocked at the connection between the feed hopper 5 and the scattering box 2.
[0028] Embodiment 2. On the basis of Embodiment 1, a jet pipe 801 is connected to the position of the throwing and spraying air box 8 corresponding to the throwing pipe 201. The jet pipe 801 extends to the bottom of the inner cavity of the throwing pipe 201 and faces the nozzle direction of the throwing pipe 201 along the air flow guiding groove 202. Six connecting air pipes 802 are connected to one end of the throwing and spraying air box 8. The other ends of the connecting air pipes 802 are connected to the upper end of the air outlet pipe 303. The ends of the six connecting air pipes 802 connected to the inner cavity of the throwing and spraying air box 8 respectively extend into the inner cavity of the throwing and spraying air box 8 and are connected to independent jet pipes 801. The blower 301 generates wind under the drive of the servo motor 6 and sends the wind into the connecting air pipes 802 through the air outlet pipe 303. The connecting air pipes 802 send the wind into the inner cavity of the throwing and spraying air box 8 respectively, and spray the wind into the corresponding throwing pipes 201 through the independent jet pipes 801. The jet pipes 801 spray the wind towards the nozzle direction of the throwing pipes 201 along the direction of the air flow guiding groove 202, increasing the throwing distance and range of the feed. When the feed is thrown up by the throwing fan 701, affected by the inclined structure of the throwing pipe 201 inclined obliquely upward and outward, the feed is guided to be thrown in a specific direction. At the same time, the throwing and spraying air box 8 sprays wind into the throwing pipe 201 through the jet pipe 801, further pushing the feed to be thrown to a farther place. The thrown feed, under the combined action of the wind force and the throwing fan 701, can cover a wider area and achieve uniform throwing.
[0029] The working principle of this embodiment: The feed enters the throwing system through the feed hopper 5. Since the feed hopper 5 is in the shape of a funnel with a wider upper part and a narrower lower part, the feed can flow smoothly downward. The feed is evenly distributed to multiple areas in the inner cavity of the throwing box 2 by the annular distribution rods 704 of the narrow upper part material dividing cone 703, ensuring the uniformity of the feed distribution. At the same time, during the rotation of the driving shaft rod 7, the rods 704 and the ball heads 705 can stir and loosen the feed while preventing the feed from sticking to the wall and bridging in the feed hopper 5, thus ensuring the feed discharging efficiency. The discharging auger 702 rotates under the drive of the driving shaft rod 7, further promoting the downward flow of the feed and preventing the feed from blocking at the connection between the feed hopper 5 and the throwing box 2. The servo motor 6 drives the driving shaft rod 7 to rotate, thereby driving the throwing fan 701 to rotate. The bottom of the throwing fan 701 is tangent to the bottom of the inner cavity of the throwing box 2, and can effectively throw the feed from the bottom. The six-blade structure of the throwing fan 701 can evenly throw the feed in all directions, ensuring the uniformity and range of the feed throwing. The blower 301 generates wind under the drive of the servo motor 6, and sends the wind into the connecting air pipe 802 through the air outlet pipe 303. The connecting air pipe 802 sends the wind into the cavity of the throwing and spraying air box 8 respectively, and sprays the wind into the corresponding throwing pipe 201 through the independent spraying pipe 801. The spraying pipe 801 sprays the wind towards the nozzle direction of the throwing pipe 201 along the direction of the air flow guiding groove 202, increasing the throwing distance and range of the feed. When the feed is lifted by the throwing fan 701, affected by the inclined structure of the throwing pipe 201 which is inclined obliquely upward and outward, the feed is guided to be thrown in a specific direction. At the same time, the throwing and spraying air box 8 sprays wind into the throwing pipe 201 through the spraying pipe 801, further pushing the feed to be thrown to a farther place. The thrown feed can cover a wider area under the combined action of the wind force and the throwing fan 701, realizing uniform throwing.
