Description

Technical Field

[0001] This utility model relates to material processing, and in particular to an electric gravity combined unloading valve, belonging to the field of unloading valve technology. Background Technology

[0002] The discharge valve adopts two connection methods: square flange and round flange. Depending on the transmission method, it can be divided into direct-drive type and chain type. The direct-drive discharge valve uses a planetary rotation principle, with input and output on the same axis. Its unique feature of directly connecting the housing and motor results in a compact structure, beautiful and novel appearance, small size, and light weight. The chain type discharge valve uses a design that keeps the bearings and gearbox away from the valve body, avoiding the influence of high temperature and dust. The front and rear end covers have good sealing performance, preventing dust leakage and extending the service life of the lubrication system of the moving parts.

[0003] A search revealed Chinese patent publication number CN219448329U, which discloses a discharge valve. Material flows into a chamber through an inlet, and the outlet is located at the bottom of the outer shell and communicates with the chamber, allowing material to flow out of the chamber. A shaft is located within the chamber and rotates around its axis in a first rotational direction. Multiple discharge grooves are provided on the outer circumferential surface of the shaft, arranged sequentially along the circumferential direction of the shaft. The extension direction of the shaft's axis is orthogonal to the height direction of the discharge valve. In a projection plane orthogonal to the shaft's axial direction, the shaft has a centerline extending along the height direction of the discharge valve, and the centerline of the outlet is located upstream of the centerline in the first rotational direction. This discharge valve has advantages such as smooth discharge, simple structure, and low cost.

[0004] Existing unloading valves have drawbacks such as easy blockage inside the bag unloading valve due to the fact that all the material is conveyed together during use, as well as reduced efficiency and weak sealing effect during unloading.

[0005] Therefore, an electric gravity combined unloading valve is proposed. Utility Model Content

[0006] In view of this, the present invention provides an electric gravity combined unloading valve to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is an electric gravity combined unloading valve, comprising: a first unloading pipe and a first unloading plate; a second unloading pipe fixedly installed at the bottom of the first unloading pipe; a flange provided at the bottom of the second unloading pipe; a first unloading plate and a second unloading plate movably installed on the inner sides of the first unloading pipe and the second unloading pipe, respectively; the first unloading plate and the second unloading plate are rotatably installed on the inner sides of the first unloading pipe and the second unloading pipe via a rotating rod; a counterweight is fixedly installed at the outer end of the rotating rod; an mounting plate is fixedly installed on the outer side of the first unloading pipe and the second unloading pipe; a motor is fixedly installed on the top of the mounting plate; and a cam corresponding to the counterweight is fixedly installed at the output end of the motor.

[0008] More preferably, a flip plate is fixedly installed at the bottom of the first unloading plate and the second unloading plate, and a connecting rod is fixedly installed at the bottom of the flip plate, with one end of the connecting rod fixedly installed to the rotating rod.

[0009] More preferably, the connecting rod and the flip plate are fixedly installed together by a mounting base, and an adjusting bolt that cooperates with the connecting rod is fixedly installed at the bottom of the flip plate.

[0010] More preferably, the inner sides of the first unloading pipe and the second unloading pipe are provided with movable grooves for the connecting rod to move, and the mounting plate is fixedly connected to the first unloading pipe and the second unloading pipe through a connecting frame.

[0011] More preferably, the output end of the motor is equipped with a cam corresponding to the other counterweight via a transmission belt, and the two cams are arranged with their high and low parts opposite to each other.

[0012] More preferably, a protective box is fixedly installed on the inner side of the mounting plate, and the transmission belt is located inside the protective box.

[0013] The present invention has the following advantages due to the adoption of the above technical solution:

[0014] This invention features a first unloading plate, a second unloading plate, a transmission belt, and a cam that works in conjunction with a counterweight. The rotation of the motor output drives the cam to rotate, and the transmission belt simultaneously drives the other cam to rotate. The higher point of the cam presses against the bottom of the counterweight, causing the first and second unloading plates to rotate around a rotating rod. Because the two cams are positioned with opposite heights, while the higher point of one cam contacts the counterweight, the lower point of the other cam contacts the bottom of the counterweight. This allows the first and second unloading plates to open alternately. The flipping of the first and second unloading plates effectively prevents blockages during unloading, making the process more convenient and efficient.

[0015] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0023] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] like Figures 1-5As shown, this utility model embodiment provides an electric gravity combined unloading valve, including: a first unloading pipe 1 and a first unloading plate 2; a second unloading pipe 101 is fixedly installed at the bottom of the first unloading pipe 1; a flange 102 is provided at the bottom of the second unloading pipe 101; the first unloading plate 2 and the second unloading plate 201 are movably installed on the inner sides of the first unloading pipe 1 and the second unloading pipe 101, respectively; the first unloading plate 2 and the second unloading plate 201 are rotatably installed on the inner sides of the first unloading pipe 1 and the second unloading pipe 101 by a rotating rod 202. A counterweight 203 is fixedly installed on the outer end of the rotating rod 202. An installation plate 103 is fixedly installed on the outer side of the first unloading pipe 1 and the second unloading pipe 101. A motor 105 is fixedly installed on the top of the installation plate 103. A cam 204 corresponding to the counterweight 203 is fixedly installed on the output end of the motor 105. A flipping plate 207 is fixedly installed on the bottom of the first unloading plate 2 and the second unloading plate 201. A connecting rod 209 is fixedly installed on the bottom of the flipping plate 207. One end of the connecting rod 209 is fixedly installed to the rotating rod 202.

[0026] The rotation of the output end of the motor 105 can drive the cam 204 to rotate, and at the same time, the transmission belt 205 can drive the other cam 204 to rotate. This allows the high point of the cam 204 to press against the bottom of the counterweight 203, thereby enabling the first unloading plate 2 and the second unloading plate 201 to rotate around the rotating rod 202. Since the high and low parts of the two cams 204 are set opposite, when the high point of the cam 204 contacts the counterweight 203, the low point of the other cam 204 contacts the bottom of the counterweight 203, thereby enabling the first unloading plate 2 and the second unloading plate 201 to open alternately.

[0027] Reference Figure 3 The connecting rod 209 and the flip plate 207 are fixedly installed by the mounting base 208. The bottom of the flip plate 207 is fixedly installed with an adjusting bolt 210 that cooperates with the connecting rod 209. The inner side of the first unloading pipe 1 and the second unloading pipe 101 is provided with a movable groove 211 for the connecting rod 209 to move. The mounting plate 103 is fixedly connected to the first unloading pipe 1 and the second unloading pipe 101 by the connecting bracket 104.

[0028] The mounting base 208 allows for easy installation of the connecting rod 209 and the flip plate 207. The adjusting bolt 210 allows for easy adjustment of the tightness and fine adjustment of the flip angle between the second unloading plate 201 and the first unloading plate 2. Meanwhile, the movable groove 211 allows the connecting rod 209 to flip together, preventing interference.

[0029] Reference Figure 5A protective box 206 is fixedly installed on the inner side of the mounting plate 103. The transmission belt 205 is located inside the protective box 206. The output end of the motor 105 is driven by the transmission belt 205 to install a cam 204 corresponding to another counterweight 203. The two cams 204 are arranged with opposite heights.

[0030] By having the high and low parts of the two cams 204 arranged oppositely, such that when the high point of the other cam 204 contacts the counterweight 203, the low point of the other cam 204 contacts the bottom of the counterweight 203, the first unloading plate 2 and the second unloading plate 201 can be opened alternately.

[0031] In operation, this invention rotates as follows: the output of motor 105 drives cam 204 to rotate, and the transmission belt 205 drives another cam 204 to rotate. This causes the high point of cam 204 to press against the bottom of counterweight 203, allowing the first unloading plate 2 and the second unloading plate 201 to rotate around the rotating rod 202. Because the high and low points of the two cams 204 are oppositely arranged, while the high point of cam 204 contacts the counterweight 203, the low point of the other cam 204 contacts the bottom of the counterweight 203. This allows the first unloading plate 2 and the second unloading plate 201 to open alternately. The flipping of the first unloading plate 2 and the second unloading plate 201 effectively prevents blockage during unloading, making it more convenient and faster to use.

[0032] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
