Description

Technical Field

[0001] This utility model relates to the technical field of grape sorting machines, and in particular to a grape sorting machine. Background Technology

[0002] A grape sorting machine is an automated or semi-automated device designed specifically for post-harvest grape processing. Its core function is to efficiently classify harvested grapes in batches according to preset sorting standards and a specific sorting mechanism. This process removes grapes that do not meet quality requirements and sorts grapes that meet the quality standards for different application scenarios into different grades. Ultimately, this device achieves grape quality grading, improves subsequent processing efficiency, and increases product added value.

[0003] When screening grapes, the conventional manual selection method is inefficient and prone to missing grapes, resulting in poor screening effect. In some grape screening devices, the screening drum method is commonly used. The grapes are placed in the screening drum and the drum is continuously screened by rolling. However, after screening, the removal of qualified grapes left inside is not very effective, which affects the screening efficiency and thus causes the problem of poor screening effect.

[0004] An existing patent (publication number: CN221908421U) discloses a grape screening machine, relating to the field of grape screening technology. It includes a base plate with two support frames fixedly mounted on its upper surface. A guide frame is placed above the base plate, and the tops of both support frames are fixedly connected to the outer side of the guide frame. Conveying rollers are placed on both sides of the guide frame, and two bearings are embedded on each side. This grape screening machine pours grapes onto conveyor columns via a guide plate. A servo motor drives the conveyor rollers to rotate, causing the conveyor belt to rotate, which in turn drives each conveyor column to rotate and move. During continuous rotation, the machine continuously conveys the grapes piled on the right side. Smaller grapes fall through the gaps between the conveyor columns and enter the guide frame, then slide outwards through the discharge chute. This allows for grape screening during the conveying process, improving the conveying and screening efficiency of the device.

[0005] To address the aforementioned issues, existing patents offer solutions. However, existing grape screening machines often suffer from inconvenient flow control during the feeding process. This makes it difficult to flexibly adjust the speed and quantity of grapes entering the screening structure according to actual screening needs, which can easily lead to a large influx of grapes into the screening area, causing material accumulation within the screening structure, affecting the normal function of the screening components, and resulting in a decrease in screening efficiency. At the same time, grapes are prone to feeding blockages during the conveying process, leading to interruptions in subsequent feeding and reducing the overall operating efficiency of the screening machine.

[0006] Therefore, a grape sorting machine is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a grape screening machine that solves the problem that existing grape screening machines often have inconvenient flow control in the feeding stage. It is difficult to flexibly adjust the speed and amount of grapes entering the screening structure according to actual screening needs, which can easily lead to a large number of grapes flooding into the screening area, causing material accumulation in the screening structure, affecting the normal function of the screening components, and reducing the screening effect. At the same time, grapes are prone to feeding blockage during the conveying process, which can lead to the interruption of subsequent feeding and reduce the overall operating efficiency of the screening machine.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a grape screening machine, comprising a screening machine structure, a feeding rack fixedly connected to the bottom of the screening machine structure, a hopper provided at the top of the feeding rack, a flexible channel fixedly connected to the bottom of the hopper, a discharging rack fixedly connected to the bottom of the flexible channel, a flow limiting mechanism inserted into the inner wall of the discharging rack, a vibration motor fixedly connected to the left side of the discharging rack, the flow limiting mechanism comprising a flow limiting plate, a fixing rod fixedly connected to the left side of the flow limiting plate, and a pull plate fixedly connected to the left side of the fixing rod.

[0009] Preferably, the surface of the flow limiting plate is inserted into the inner wall of the unloading rack, and the inner wall of the unloading rack is provided with an adjustment groove that cooperates with the flow limiting plate.

[0010] Preferably, a knob is movably connected to the inner wall of the feeding rack, and the surface of the knob is threadedly connected to the inner wall of the flow restrictor.

[0011] Preferably, the inner wall of the flow restrictor is provided with a threaded groove for use with the knob, and the inner wall of the unloading rack is provided with a mounting hole for use with the knob.

[0013] Preferably, a support block is fixedly connected to the right side of the mounting block, and the bottom of the support block is fixedly connected to the top of the screening machine structure.

[0014] Preferably, a support assembly is fixedly connected to the right side of the hopper, and the bottom of the support assembly is fixedly connected to the top of the screening machine structure.

[0015] Preferably, the inner wall of the feeding rack is provided with a material passage groove, and the front side of the screening machine structure is fixedly connected to the discharge rack.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application sets up a flow-limiting mechanism, which can regulate the conveying speed and flow rate of grapes in the feeding rack through the flow-limiting plate. Combined with the convenient operation structure formed by the fixed rod and the pull plate, the user can quickly adjust the flow-limiting state without complicated operation. It can effectively prevent grapes from entering the inner wall of the screening machine structure in a large quantity and at a high flow rate, and prevent excessive load on the screening area due to excessive accumulation of grapes. This avoids problems such as decreased screening accuracy and poor screening effect caused by uneven material distribution, and ensures the stability and screening quality of the screening process.

[0018] 2. This application incorporates a feeding rack that easily receives grapes discharged from the unloading rack. The hopper allows for centralized temporary storage and initial feeding of grapes. The flexible channel buffers the impact of falling grapes, reducing damage to the grape skin and protecting grape quality. The unloading rack provides a directional channel for grape transport, and the vibrating motor fixed on its left side promotes even dispersion of grapes during transport through vibration, effectively breaking the adhesion between grapes and preventing blockage of the unloading channel and grape accumulation. This ensures continuous and smooth transport of grapes from feeding to screening, improving overall screening efficiency. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 The present invention provides the following technical solution:

[0028] A grape sorting machine includes a sorting machine structure 1. A feeding rack 3 is fixedly connected to the bottom of the sorting machine structure 1. A hopper 4 is provided at the top of the feeding rack 3. A flexible channel 5 is fixedly connected to the bottom of the hopper 4. A discharging rack 6 is fixedly connected to the bottom of the flexible channel 5. A flow limiting mechanism 2 is inserted into the inner wall of the discharging rack 6. A vibration motor 7 is fixedly connected to the left side of the discharging rack 6. The flow limiting mechanism 2 includes a flow limiting plate 201. A fixing rod 202 is fixedly connected to the left side of the flow limiting plate 201. A pull plate 203 is fixedly connected to the left side of the fixing rod 202.

[0029] In this embodiment: By setting a flow-limiting mechanism 2, the flow-limiting mechanism 2 can regulate the conveying speed and flow rate of grapes in the unloading rack 6 through the flow-limiting plate 201. Combined with the convenient operating structure formed by the fixed rod 202 and the pull plate 203, the user can quickly adjust the flow-limiting state without complicated operations. This effectively prevents grapes from entering the inner wall of the screening machine structure 1 in large quantities and at high speeds, preventing excessive load on the screening area due to excessive grape accumulation. This avoids problems such as decreased screening accuracy and poor screening effect caused by uneven material distribution, ensuring the stability and quality of the screening process. The system utilizes a feeding rack 3 to receive grapes discharged from the unloading rack 6. A hopper 4 provides centralized temporary storage and initial feeding of grapes. A flexible channel 5 buffers the impact of falling grapes, reducing skin damage and protecting grape quality. The unloading rack 6 provides a directional channel for grape transport. A vibrating motor 7 fixed to its left side promotes even dispersion of grapes during transport, effectively breaking the adhesion between grapes and preventing blockages in the unloading channel and grape accumulation. This ensures continuous and smooth transport of grapes from feeding to screening, improving overall screening efficiency.

[0030] Specifically, such as Figure 5 As shown, the surface of the flow limiting plate 201 is inserted into the inner wall of the unloading rack 6, and the inner wall of the unloading rack 6 is provided with an adjustment groove 8 that works in conjunction with the flow limiting plate 201.

[0031] Specifically, such as Figure 5 As shown, a knob 9 is movably connected to the inner wall of the unloading rack 6, and the surface of the knob 9 is threadedly connected to the inner wall of the flow limiting plate 201.

[0032] Specifically, such as Figure 5 , Figure 6 As shown, the inner wall of the flow restrictor 201 is provided with a threaded groove 10 that cooperates with the knob 9, and the inner wall of the feed rack 6 is provided with a mounting hole 11 that cooperates with the knob 9.

[0033] In this embodiment: the adjustment groove 8 on the inner wall of the feeding rack 6 facilitates the sliding of the flow limiting plate 201 on the inner wall of the feeding rack 6, which facilitates subsequent adjustment of the feeding flow rate. The knob 9 is provided so that the position of the flow limiting plate 201 can be restricted by rotating the knob 9 on the inner wall of the feeding rack 6 and the flow limiting plate 201 during use, thus preventing the flow limiting plate 201 from shifting during use. The threaded groove 10 (multiple sets of threaded grooves 10) on the inner wall of the flow limiting plate 201 facilitates the rotation of the knob 9 on the inner wall of the flow limiting plate 201 through the threaded groove 10. The mounting hole 11 on the inner wall of the feeding rack 6 facilitates the rotation of the knob 9 on the inner wall of the feeding rack 6 through the mounting hole 11.

[0034] Specifically, such as Figure 4 As shown, spring frames 12 are fixedly connected to both the front and rear sides of the unloading rack 6, and mounting blocks 13 are fixedly connected to the side of the spring frames 12 away from the unloading rack 6.

[0035] Specifically, such as Figure 4 As shown, a support block 14 is fixedly connected to the right side of the mounting block 13, and the bottom of the support block 14 is fixedly connected to the top of the screening machine structure 1.

[0036] In this embodiment: by setting the spring frame 12 and the mounting block 13, the spring frame 12 can buffer the vibration generated when the vibrating motor 7 is working, reduce the transmission of vibration to the screening machine structure 1 and other components. The cooperation between the mounting block 13 and the support block 14 provides a stable support and positioning for the feeding rack 6, ensuring that the feeding rack 6 can maintain a stable relative position with the screening machine structure 1 under vibration, preventing the feeding rack 6 from tilting or shifting due to vibration, ensuring the smooth flow of the grape conveying channel, and avoiding grape spillage or conveying interruption.

[0037] Specifically, such as Figure 3 As shown, a support assembly 15 is fixedly connected to the right side of the hopper 4, and the bottom of the support assembly 15 is fixedly connected to the top of the screening machine structure 1.

[0038] Specifically, such as Figure 2 , Figure 5 As shown, the inner wall of the feeding rack 6 is provided with a material passage trough 16, and the front side of the screening machine structure 1 is fixedly connected to the discharge rack 17.

[0039] In this embodiment: by setting the support component 15, the hopper 4 can be provided with additional support and fixation, which enhances the structural stability of the hopper 4 during temporary storage and material guiding, prevents the hopper 4 from tilting or breaking at the connection with the flexible channel 5 due to the excessive weight of the grapes in the hopper 4, and ensures the reliability of the feeding process. The material passage trough 16 on the inner wall of the feeding rack 6 can guide the grapes in a directional manner, ensuring that the grapes enter the feeding rack 3 along the preset path. The discharge rack 17 on the front side of the screening machine structure 1 can guide the screening grapes to output, which is convenient for subsequent collection and processing of grapes of different grades, optimizes the material flow process after screening, and improves the overall processing efficiency.

[0040] Working Principle: During the use of the screening machine structure 1, a flow-limiting mechanism 2 is set up. The flow-limiting mechanism 2, through the flow-limiting plate 201, can regulate the conveying speed and flow rate of grapes in the feeding rack 6. Combined with the convenient operation structure formed by the fixed rod 202 and the pull plate 203, the user can quickly adjust the flow-limiting state without complicated operations. This effectively prevents grapes from entering the inner wall of the screening machine structure 1 in large quantities and at high speeds, preventing excessive load on the screening area due to excessive grape accumulation. This avoids problems such as decreased screening accuracy and poor screening effect caused by uneven material distribution, ensuring the stability and quality of the screening process. The feeding rack 3 is set up to receive grapes discharged from the feeding rack 6. The hopper 4 can realize centralized temporary storage and initial material guidance of grapes. The flexible channel 5 can buffer the impact force when grapes fall, reducing damage to the grape skin and protecting it. To ensure grape quality, the feeding rack 6 provides a directional channel for grape conveying. The vibrating motor 7 fixed on its left side can promote the even distribution of grapes during the conveying process through vibration, effectively breaking the stickiness between grapes and avoiding blockage of the feeding channel and stagnation of grapes. This ensures continuous and smooth conveying of grapes from feeding to screening, improving the overall screening efficiency. By setting up a spring frame 12 and a mounting block 13, the spring frame 12 can buffer the vibration generated by the vibrating motor 7 during operation, reducing the transmission of vibration to the screening machine structure 1 and other components. The cooperation between the mounting block 13 and the support block 14 provides stable support and positioning for the feeding rack 6, ensuring that the feeding rack 6 can maintain a stable relative position with the screening machine structure 1 even under vibration, preventing the feeding rack 6 from tilting or shifting due to vibration, ensuring the smooth flow of the grape conveying channel, and avoiding grape spillage or conveying interruption.

[0041] 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.
