Description

Technical Field

[0001] This utility model belongs to the technical field of concrete mixing equipment, specifically relating to a unloading mechanism that simultaneously meets the requirements of both railcar and mixer truck for receiving materials. Background Technology

[0002] In industries such as metallurgy, building materials, and mining, unloading mechanisms are key equipment for material transfer and are widely used in the receiving operations of transport vehicles such as railcars and concrete mixer trucks. Traditional unloading mechanisms are mostly constructed from welded steel structures, using fixed chutes or simple transfer devices to guide material flow. However, with increasing demands for efficiency, environmental protection, and equipment durability in industrial settings, existing technologies have revealed the following shortcomings:

[0003] Currently, the discharge height of the hopper at the discharge port of concrete mixing equipment is fixed, which can only meet the needs of equipment with similar discharge heights. Moreover, commercial mixing plants in the market use railcars for receiving materials, which have a relatively high discharge height and have rails passing under the discharge port, making it difficult to simultaneously meet the needs of mixer trucks. Therefore, a discharge mechanism that can simultaneously meet the needs of both railcars and mixer trucks is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a discharge mechanism that can simultaneously meet the needs of both railcars and mixer trucks for receiving materials. It solves the problem that the discharge height of the existing material collection hopper is fixed, which can only meet the needs of equipment with similar discharge heights and the use of railcars for receiving materials. The discharge height is relatively high and there is a rail passing under the discharge port, making it difficult to simultaneously meet the needs of mixer trucks for receiving materials.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a material unloading mechanism that simultaneously meets the requirements of receiving materials from both railcars and mixer trucks, including a material gathering hopper, a sluice chute, a track, and a control system. The material gathering hopper is funnel-shaped, the sluice chute includes a frame with a chute fixed on it, wheels at both ends of the frame, the chute includes a bucket body with a discharge port at the bottom, a vibrator on the bucket body, and a liner on the inner wall of the bottom of the bucket body. The track includes an I-beam and a support frame, and the control system includes a drive device and a proximity sensor.

[0006] Preferably, limiting components are provided on both sides of the track to restrict the chute. The limiting components are made of polyurethane buffer blocks or rubber buffer blocks with a Shore hardness of 70-90HA.

[0007] Preferably, the material of the hopper is Q345B low alloy steel plate, the bottom inclination angle of the hopper is 30-45°, and the inner wall of the hopper is lined with a plate.

[0008] Preferably, the I-beam is made of Q235B carbon structural steel.

[0009] Preferably, the vibrator is equipped with an IP55 protection-rated motor.

[0010] Preferably, the proximity sensor and the drive device are connected to a PLC control system.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. This utility model can simultaneously meet the material receiving needs of equipment such as railcars and mixer trucks, and the unloading process is automatically controlled;

[0013] 2. This utility model can simultaneously meet the material receiving functions of railcars and mixer trucks, solving the problem that the material unloading height of the existing material hopper is fixed, which can only meet the material receiving of equipment with similar unloading heights and the material receiving of railcars. The unloading height is high and there is a rail passing under the unloading port, which makes it difficult to meet the material receiving function of mixer trucks at the same time.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figure 1-2 As shown, a material unloading mechanism that simultaneously meets the material receiving requirements of railcars and mixer trucks includes a material gathering hopper 1, a transfer chute 2, a track 3, and a control system 4. The material gathering hopper 1 is funnel-shaped, which concentrates and guides the material. The funnel-shaped design can concentrate and guide materials such as concrete to the transfer chute 2, avoid material scattering, optimize the material flow speed, and adapt to the different material receiving height requirements of the high unloading port of the railcar and the low unloading port of the mixer truck.

[0021] The ferry chute 2 includes a frame 5, on which the chute is fixed. Wheels 6 are installed at both ends of the frame 5. The ferry chute 2 moves on the track 3 via the wheels 6, flexibly switching unloading positions and covering the receiving area between the track 3 vehicle and the mixer truck. The chute includes a bucket body 7, with a discharge port 8 at the bottom for material discharge. The length of the discharge port 8 is designed according to the height of the receiving equipment below. A vibrator 9, using the YZO series, is installed on the bucket body 7 to generate high-frequency vibration, accelerating material flow and preventing material accumulation. A liner 10 is installed on the inner wall of the bottom of the bucket body 7. The liner 10 is made of 16Mn 20-40mm thick wear-resistant steel plate, which has high hardness and strong impact resistance, reducing maintenance frequency. The track 3 includes I-beams and a support frame. The I-beams are 36C type, conforming to GB / T706-2016 standard. The support frame connects the I-beams to form a stable sliding track 3, supporting the movement of the ferry chute 2. The control system 4 includes a drive unit and proximity sensors.

[0022] The specific design of the aforementioned key components will be discussed in detail below:

[0023] Limiting components are installed on both sides of the track 3 to restrict the swing chute 2. The limiting components are made of polyurethane buffer blocks or rubber buffer blocks with a Shore hardness of 70-90HA. The preferred dimensions of the limiting components are length × width × height = 200 × 100 × 50 mm. The actual dimensions are adapted according to the width of the track 3. The limiting components are fixed to both sides of the track 3 with M16 bolts.

[0024] Mechanical limiters restrict the movement range of the ferry chute 2 to prevent it from derailing, and absorb the impact energy during the movement of the chute through the elastic deformation of the material.

[0025] The material collection hopper 1 is made of Q345B low alloy steel plate. The bottom inclination angle of the material collection hopper 1 is 30-45°, and the inner wall of the material collection hopper 1 is provided with a liner plate 10. The bottom inclination angle of the material collection hopper 1 is selected according to the flowability of the material, such as 40° commonly used for concrete. The liner plate 10 is fixed by countersunk bolts. The inclination angle optimizes the flow of material by its own weight and reduces the need for manual cleaning.

[0026] The I-beams are made of Q235B carbon structural steel. The supporting frame columns are 200×200×8mm Q235B square steel tubes; the crossbeams are double-jointed 36C I-beams, connected to the columns by welding or high-strength bolts. The I-beam track 3 has a load-bearing capacity of ≥10 tons, supporting the reciprocating motion of the shuttle chute 2. The I-beam section has a large moment of inertia and strong resistance to bending deformation.

[0027] The vibrator 9 is equipped with an IP55 protection-rated motor. The motor is selected as an IP55 protection-rated three-phase asynchronous motor, such as the YE3 motor series. The vibrator 9 is fixed to the side of the chute body 7 via a flange, and a rubber shock-absorbing pad is installed between the vibrator 9 and the outer wall of the chute body 7.

[0028] The proximity sensor and drive unit are connected to the PLC control system 4. The drive unit adopts a Y-series three-phase asynchronous motor, which is driven by a reducer and gear rack. The proximity sensor is selected as an Omron E2E-X series proximity sensor. The PLC system is selected as a Siemens S7-1200 controller, matched with an SM1223 digital input module. The following logical position closed-loop control is implemented: sensor detects the chute position → PLC compares the target position → drive motor forward / reverse → chute is accurately positioned.

[0029] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
