Description

Technical Field

[0001] This application relates to the technical field of lifting equipment, and in particular to a bucket elevator capable of multi-point unloading. Background Technology

[0002] During the harvesting, processing, and storage of agricultural seeds, lifting equipment is often used to transport them to different silos, warehouses, or packaging lines for further processing.

[0003] Currently, traditional bucket elevators typically employ a single-point discharge design, where seeds are vertically lifted through the buckets and transported only to a single outlet. In scenarios requiring multi-point discharge, companies often need to configure multiple elevators to operate in parallel, resulting in large equipment footprints, high energy consumption, and difficulties in coordination.

[0004] Therefore, a new seed-raising device is urgently needed. Summary of the Invention

[0005] To address the issue that existing bucket elevators are unsuitable for multi-point unloading scenarios due to their single-point unloading capability, this application provides a bucket elevator capable of multi-point unloading.

[0006] This application provides a bucket elevator capable of multi-point unloading, employing the following technical solution: A bucket elevator capable of multi-point unloading includes The elevator body has an inlet and an outlet; A feeding assembly is provided on the elevator body, the feeding assembly includes a feeding bin, the discharge port of the feeding bin facing the inlet of the elevator body; A discharge assembly is mounted on the elevator body. The discharge assembly includes a guide cylinder, a protective cover, a telescopic chute, an alignment mechanism, and a discharge cylinder. The guide cylinder is detachably fixed to the elevator body and its top end is connected to the discharge port of the elevator body. The protective cover is fixed to the guide cylinder and has a cavity. The bottom end of the guide cylinder passes through the protective cover. The telescopic chute is located in the cavity of the protective cover, and its inlet end is connected to the bottom end of the guide cylinder. The alignment mechanism includes an alignment retaining ring located inside the protective cover and reciprocating. The discharge end of the telescopic chute passes through the alignment retaining ring. Multiple discharge cylinders are arranged side by side outside the protective cover, and each discharge cylinder is connected to the cavity of the protective cover. The control box is mounted on the elevator body and electrically connected to the elevator body, the feeding assembly, and the discharging assembly; When multiple discharge points are required, the alignment retaining ring moves the discharge end of the telescopic chute above the corresponding discharge cylinder.

[0007] By adopting the above technical solution.

[0008] Optionally, the alignment mechanism further includes: The alignment chain rotates cyclically within the cavity of the protective cover, and the alignment retaining ring is connected to the alignment chain; A dustproof compartment is attached to the outer side of the protective cover; The positive motor is located inside the dustproof chamber; The first pair of positive sprockets is located at the output end of the positive motor; The second pair of positive sprockets is rotatably disposed inside the protective cover, and the positive chain, the first pair of positive sprockets, and the second pair of positive sprockets form a chain drive structure.

[0009] By adopting the above technical solution, stable operation of the symmetrical retaining ring is achieved, and the entire alignment mechanism has a more compact structure. Simultaneously, the dustproof chamber isolates the alignment motor from the material environment, extending the motor's service life and preventing dust intrusion from affecting operation.

[0010] Optionally, the alignment mechanism further includes a support base connected to the inner wall of the protective cover, and the second alignment sprocket is rotatably mounted on the support base.

[0011] By adopting the above technical solution, the stability of the alignment ring during movement is enhanced, ensuring accurate alignment of the telescopic chute.

[0012] Optionally, the alignment mechanism further includes an alignment sensor, which is disposed on the inner wall of the protective cover and used to sense the alignment retaining ring. The alignment sensor and the discharge cylinder are arranged in a one-to-one correspondence.

[0013] By adopting the above technical solutions, automated positioning control can be achieved, improving alignment accuracy and response speed, avoiding misoperation, and enhancing the system's intelligence level.

[0014] Optionally, the positive alignment mechanism further includes a negative pressure pump and a negative pressure pipe, with one end of the negative pressure pipe connected to the negative pressure pump and the other end connected to the dustproof chamber.

[0015] By adopting the above technical solution, the dustproof effect is further improved. The negative pressure suction removes dust that may enter the dustproof chamber, protecting the positive motor and extending its service life.

[0016] Optionally, the protective cover includes a cover body and a base plate, the base plate being detachably fixed to the cover body, and the discharge cylinder being fixed to the cover body.

[0017] By adopting the above technical solution, it is easy to change the configuration of different numbers of discharge cylinders, enhance the adaptability and modularity of the equipment, and expand the application scenarios.

[0018] Optionally, the end of the discharge cylinder that penetrates into the cavity of the protective cover is funnel-shaped.

[0019] By adopting the above technical solutions, materials are guided smoothly into the discharge cylinder, reducing spillage and blockage, and improving the smoothness and reliability of unloading.

[0020] Optionally, the feeding assembly further includes a feeding base, a guide plate, and a vibrator. The feeding base is disposed on the elevator body, the guide plate is located below the feeding hopper, and the vibrator is connected to the feeding base and the guide plate respectively. The vibrator is used to generate vibration and transmit the vibration to the guide plate.

[0021] By adopting the above technical solution, the material is prevented from adhering to the guide plate, the feeding speed is accelerated, and it is especially suitable for powdery or easily caking seeds, thus improving the feeding efficiency.

[0022] Optionally, the vibrating body includes a vibrating spring, a vibrating transmission plate, and a vibrating motor. The vibrating motor is fixed on the feeding base, the vibrating transmission plate is connected to the bottom of the guide plate, and one end of the vibrating spring is connected to the vibrating motor, while the other end is connected to the vibrating transmission plate.

[0023] By adopting the above technical solution, efficient vibration transmission is achieved. The structure is simple and reliable, maintenance is convenient, and it is suitable for working conditions with frequent start and stop.

[0024] Optionally, the vibrator further includes a vibration shield connected to the feeding base and used to protect the vibration motor.

[0025] By adopting the above technical solutions, the vibrating body is protected from external collisions and contamination, improving the durability and safety of the equipment and extending its service life.

[0026] In summary, this application includes at least one of the following beneficial technical effects: By incorporating a discharge assembly with a guide tube, protective cover, telescopic chute, alignment mechanism, and multiple discharge cylinders, flexible multi-point unloading of agricultural seeds after lifting is achieved. The telescopic chute, within the protective cover, utilizes a movable alignment ring to control the position of its discharge end, ensuring precise alignment with different discharge cylinders and guiding the seeds into different hoppers. This structure overcomes the limitation of traditional bucket elevators that can only discharge from a single outlet, avoiding the problems of large footprint, high energy consumption, and complex coordination associated with configuring multiple devices to meet multi-point feeding needs. It significantly improves the equipment's applicability and operational efficiency, making it particularly suitable for multi-process collaborative operations such as seed processing, packaging, and storage.

[0027] By setting up alignment sensors and arranging them one-to-one with each discharge cylinder, combined with the coordinated control of the alignment chain, alignment motor, first alignment sprocket, and second alignment sprocket, precise positioning and automatic alignment of the discharge end of the telescopic chute are achieved. When it is necessary to switch the discharge point, the alignment sensors sense the position of the alignment retainer in real time and send a signal back to the control box to control the start and stop of the alignment motor, ensuring that the chute outlet stops accurately above the target discharge cylinder. This not only improves the positioning accuracy and response speed of the discharge process, but also significantly reduces positioning deviations or operational errors caused by manual adjustments.

[0028] By setting up a dustproof chamber and a negative pressure system, the positive motor is isolated from the material environment. The negative pressure pump and negative pressure pipe continuously extract any dust that may enter the dustproof chamber, effectively preventing dust accumulation from affecting the motor operation and transmission accuracy. This improves the adaptability and durability of the equipment in the conveying of materials that are prone to dust, such as seeds, reduces the failure rate, and ensures the long-term stable operation of the equipment.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0032] refer to Figure 1 and Figure 4 A bucket elevator capable of multi-point unloading includes an elevator body 1, a feeding assembly 2, a discharge assembly 3, and a control box 4. The elevator body 1 is a horizontal bucket elevator with an inlet and an outlet. The plane containing the inlet is parallel to the horizontal plane, and the plane containing the outlet is also parallel to the horizontal plane. The height of the outlet plane is greater than the height of the inlet plane. The bottom of the elevator body 1 is also equipped with casters and adjustable feet. The elevator body 1 is moved using the casters, and the adjustable feet are used to adjust the height of the elevator body 1.

[0033] refer to Figure 8 and Figure 9 The feeding assembly 2 includes a feeding bin 201, a feeding base 202, a guide plate 203, and a vibrator. Both the feeding hopper 201 and the feeding base 202 are connected to the elevator body 1. The feeding base 202 is located below the feeding hopper 201. The guide plate 203 is connected below the feeding hopper 201, and the discharge end of the guide plate 203 faces the inlet of the elevator body 1. The vibrating body is located between the feeding base 202 and the feeding hopper 201. The vibrating body includes a vibrating spring 204, a vibrating transmission plate 205, and a vibrating motor 206. The vibrating motor 206 is connected to the vibrating base, the vibrating transmission plate 205 is connected to the bottom of the guide plate 203, and one end of the vibrating spring 204 is connected to the vibrating transmission plate 205, and the other end is connected to the vibrating motor 206. The vibrating motor 206 transmits power to the guide plate 203 through the vibrating spring 204, thereby not only accelerating the movement speed of the material on the guide plate 203, but also preventing the adhesion of powdery materials on the guide plate 203.

[0034] It should be noted that the vibration motor 206 can also be replaced by a vibration electromagnet. The vibration electromagnet is connected to an external power source through wires. By repeatedly switching the power on and off, the vibration electromagnet generates magnetic attraction and dissipates electromagnetic force. At this time, a magnet is provided at the end of the vibration spring 204 facing the vibration electromagnet. Through the intermittent attraction between the magnet and the vibration electromagnet, the vibration spring 204 is compressed and extended, thereby transmitting vibration to the vibration transmission plate 205.

[0035] refer to Figure 8 In order to improve the service life of the vibrator and protect the vibrator, the feeding assembly 2 also includes a vibration cover 207. The vibration cover 207 is connected to the vibration base and is fitted over the vibrator. The vibration cover 207 is made of plastic and can prevent external objects from colliding with the vibrator.

[0036] refer to Figure 6 and Figure 7 The discharge assembly 3 includes a guide cylinder 301, a protective cover 302, a telescopic chute 303, an alignment mechanism, and a discharge cylinder 304. The guide cylinder 301 is detachably connected to the discharge port of the elevator body 1. The guide cylinder 301 is V-shaped, with its larger opening communicating with the discharge port of the elevator body 1, and its smaller opening communicating with the cavity of the protective cover 302. The protective cover 302 is connected to the guide cylinder 301, and the protective cover 302 and the guide cylinder 301 are fixed together by welding using a connecting rod. The protective cover 302 has a cavity, and the telescopic chute 303 is located inside the protective cover 302. The inlet end of the telescopic chute 303 is fixed to the bottom end of the guide cylinder 301 in the form of a clamp. The outlet end of the telescopic chute 303 is connected to the alignment ring 305 of the alignment mechanism. The alignment mechanism includes the alignment ring 305, which reciprocates inside the protective cover 302. There are multiple discharge cylinders 304, all of which are connected to the protective cover 302. The discharge cylinders 304 communicate with the cavity of the protective cover 302, and the communication point is located below the telescopic chute 303. That is, the telescopic chute 303 moves above the discharge cylinder 304 by means of the alignment ring 305.

[0037] The control box 4 is installed on the hoist body 1 and controls the operation of the electrical components in the entire equipment.

[0038] refer to Figure 7The alignment mechanism includes an alignment chain 306, an alignment gear 309, an alignment motor 308, a dustproof chamber 307, a first alignment sprocket 309, and a second alignment sprocket 310. The alignment chain 306 rotates cyclically inside the protective cover 302. The alignment retainer 305 is connected to a link of the alignment chain 306 via a connecting rod. The dust chamber 307 is located outside the protective cover 302 and is connected to the side of the protective cover 302. The alignment motor 308 is located inside the dust chamber 307. The first alignment sprocket 309 is fixed to the output end of the alignment motor 308 via a coupling. The second alignment chain 310 is rotatably installed inside the protective cover. A chain drive structure is formed between the alignment chain 306, the first alignment sprocket 309, and the second alignment sprocket 310. The alignment motor 308 is electrically connected to the control box 4. By rotating the alignment motor 308 in both directions, the alignment retainer 305 can finally achieve linear reciprocating movement. During the reciprocating movement of the positive retaining ring 305, the discharge end of the telescopic chute 303 moves above the discharge cylinder 304, thereby introducing the material in the telescopic chute 303 into the corresponding discharge cylinder 304, thus realizing multi-point unloading of the entire equipment.

[0039] refer to Figure 5 By placing the dustproof chamber 307 outside the protective cover 302 and placing the alignment motor 308 inside the dustproof chamber 307, it is possible to prevent materials from entering the alignment motor 308 during the transmission process, thereby affecting the performance of the alignment motor 308 and, in severe cases, reducing the service life of the alignment motor 308.

[0040] To further reduce the impact of materials on the positive motor 308, a negative pressure condition is set in the dustproof chamber 307. One end of the negative pressure pipe 312 is connected to the negative pressure pump, and the other end is connected to the dustproof chamber 307. The negative pressure pump creates a negative pressure environment inside the dustproof chamber 307, so that even if a small amount of dust enters the dustproof chamber 307 from the protective cover 302, it will enter the negative pressure pipe 312 under the negative pressure condition.

[0041] It should be noted that if the workshop has a negative pressure system for environmental protection, then the dustproof chamber 307 only needs to be incorporated into the existing environmental negative pressure system.

[0042] refer to Figure 7 In order to improve the stability of the alignment shackle 305 during movement, the alignment mechanism also includes a support base, which is located inside the protective cover 302. The second alignment sprocket 310 is rotatably mounted on the support base, which can prevent the second alignment sprocket 310 from swinging randomly, thereby improving the stability of the alignment chain 306 during movement.

[0043] refer to Figure 7To ensure that the discharge end of the telescopic chute 303 accurately stops above the corresponding discharge cylinder 304, an alignment sensor 311 is installed inside the protective cover 302. The alignment sensor 311 is fixed to the inner wall of the protective cover 302 and is electrically connected to the control box 4. The alignment sensor 311 is used to sense the alignment retaining ring 305. The number of alignment sensors 311 is the same as the number of discharge cylinders 304, and they are in a one-to-one correspondence. When the corresponding discharge cylinder 304 needs to work, the corresponding alignment sensor 311 will enter the working state. Then, during the movement of the alignment retaining ring 305, when the alignment sensor 311 senses the corresponding alignment retaining ring 305, the alignment sensor 311 transmits a signal to the control box 4. The control box 4 will then stop the alignment motor 308 from rotating, thereby stopping the movement of the alignment chain 306, and finally stopping the movement of the alignment retaining ring 305.

[0044] To enable rapid changes in material quantity during multi-point unloading, the protective cover 302 consists of a cover body and a base plate. The base plate is bolted to the cover body. The base plate and discharge cylinders 304 are first fixed, and then attached to the protective cover 302. Different base plates can correspond to different discharge cylinders 304; that is, the first base plate corresponds to two discharge cylinders 304, the second to three, and the third to four. Different base plates are selected to meet different needs. This connection method expands the application range of the equipment and improves material distribution efficiency.

[0045] In order to allow the material to smoothly enter the discharge cylinder 304 from the telescopic chute 303, the end of the discharge cylinder 304 that enters the protective cover 302 is made into a funnel shape.

[0046] It should be noted that the discharge end of the discharge cylinder 304 is connected to the external warehouse through a pipe. Therefore, the spacing between the discharge cylinders 304 is not constant and can be adjusted as needed. That is, the same size base plate can correspond to different numbers of discharge cylinders 304.

[0047] The implementation principle of a bucket elevator capable of multi-point unloading according to an embodiment of this application is as follows: When materials need to be stored, the materials first enter the feeding bin 201, and then enter the inlet of the elevator body 1. The elevator body 1 continuously transports the materials to the outlet, and then transports them through the guide pipe to the telescopic chute 303. The materials enter the discharge cylinder 304 from the telescopic chute 303, and finally flow into the corresponding warehouse. When the corresponding warehouse is full and a new warehouse needs to be replaced, the elevator body 1 stops working, and then the aligning ring 305 moves the discharge end of the telescopic chute 303 to the top of the corresponding discharge cylinder 304. Then the elevator body 1 restarts working until all materials are filled.

[0048] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
