Description

Material discharging device

Technical Field

The application relates to the field of concrete mixing equipment, in particular to a discharging device.

Background

At present, in the process of feeding mortar or other fluid bodies, the mortar is transported to a specified place and then transferred to a specified position manually or by auxiliary equipment (a shovel). Because of manual control, the required mortar amount cannot be controlled, and meanwhile, unnecessary waste is easily caused. In addition, the container for containing mortar is convenient for manual material taking and placing, is easy to leak and can not be sealed against water.

In view of the above, there is a need for a controllable fluid body discharging device.

SUMMERY OF THE UTILITY MODEL

In order to improve, even solve the problem that the mortar container takes place the leakage of discharge passage easily in the transportation, this application has proposed a blowing device.

The application is realized as follows:

in a first aspect, examples of the present application provide a discharge apparatus.

The discharging device comprises a hopper, a discharging device and a stop block.

Wherein, the hopper has by the lateral wall limited and be used for holding the chamber of material. The lateral wall of hopper is formed by first end to the second end extension, and the second end sets up the feed inlet.

Wherein the emptying device is connected to the first end of the side wall. The discharging device is provided with a discharging channel and a discharging hole which are communicated with the containing cavity, and the discharging hole is limited by an inclined plane.

Wherein the stopper is configured to be selectively inserted into or released from the drain opening. The stopper has an inclined contact surface, and the contact surface can cooperate with the inclined surface in a surface contact manner to close the discharge opening.

The blowing device is as the container of splendid attire material, can add the material through the feed inlet and arrange the material through the drain hole. Because drain hole and dog set up through the surperficial complex mode of slope, because both are wedge-shaped cooperation, consequently, can control the leakproofness of drain hole through both cooperation degree well. For example, the stopper is inserted more into the drain opening, and the stopper is pressed more tightly, so that the drain opening can be closed more tightly. And the stop block can be taken out to discharge the materials conveniently. So, the blowing device can compromise the function in two aspects of splendid attire and discharge material.

With reference to the first aspect, in a first possible implementation manner of the first aspect of the present application, the discharge opening is defined by two opposite inclined surfaces, and the stopper has two opposite contact surfaces, and the two inclined surfaces and the two contact surfaces can be in surface contact fit.

The discharge hole and the stop block are designed to be of a double-vamp structure, so that the sealing performance of the discharge hole during sealing is improved.

In combination with the first possible implementation manner of the first aspect, in a second possible implementation manner of the first aspect of the present application, the discharger is cylindrical.

With reference to the first aspect, in a third possible implementation of the first aspect of the present application, the material discharge channel is disposed at a height lower than or equal to a bottom disposed height of the accommodating cavity to allow the material in the accommodating cavity to be completely discharged from the material discharge channel.

The mounting position of the discharging device is limited, and the whole discharging channel of the discharging device is lower than the containing cavity of the hopper, so that the material in the hopper can automatically flow out of the discharging channel under the action of gravity. This avoids incomplete discharge of material from the hopper, and in particular avoids problems with the material in the bottom of the hopper being prone to accumulation and not being discharged.

In combination with the third possible implementation manner of the first aspect, in a fourth possible implementation manner of the first aspect of the present application, the discharge channel has an inclined inner surface. The discharge channel has a proximal end adjacent the hopper and a distal end distal from the hopper. The height of the proximal end is greater than the height of the distal end relative to the first end of the hopper.

Through setting up the selection to the blowing access structure, the blowing passageway can discharge the material more conveniently and can avoid or alleviate the material refluence to a certain extent. This gives a considerable appearance of the discharge when the material is relatively much more in the early stages of discharge.

With reference to the first aspect, in a fifth possible implementation manner of the first aspect of the present application, the stopper is made of an elastic material, and the stopper can be inserted into the material discharging opening in an interference fit manner.

Because the stop block has elasticity, the stop block can be stressed to shrink to a certain degree and restore the shape when the external force is partially or completely eliminated. Thus, the stopper can be pressed and held in the discharge opening by springback when the external force is properly removed. Thus, the block is deformed to be embedded into the material outlet by applying enough acting force, and the block can restore partial structure to be tightly filled into the material outlet when the block is properly released.

In a sixth possible implementation manner of the first aspect of the present application in combination with the first aspect, the discharging device includes a stopper disposed adjacent to the discharging device, and the stopper defines two sides of the discharging hole to restrict the stopper from being inserted into or separated from the discharging hole in a certain direction.

The stop may provide a constraint on the degree of freedom of the stop to avoid movement thereof in an undesired direction, thereby improving stability of the filling in the discharge opening.

With reference to the first aspect or the first to sixth possible implementation manners of the first aspect, in a seventh possible implementation manner of the first aspect of the present application, the material discharging device includes a push rod, two ends of the push rod are respectively hinged to the stopper and a side wall of the hopper, and the push rod can be operated to drive the stopper to be inserted into or detached from the material discharging opening.

The arrangement of the push rod driving block is beneficial to simplifying the control mode of the block, and simultaneously, the block is selectively maintained in the states of closing the discharge hole and opening the discharge hole, thereby being beneficial to smooth discharge and the transfer motion of the contained materials.

In an eighth possible implementation manner of the first aspect of the present application in combination with the seventh possible implementation manner of the first aspect, the emptying device comprises an electric motor cooperating with the push rod, and the electric motor is used for operating the push rod to drive the stopper.

The stopper is electrically driven to improve the operation efficiency and speed.

In a ninth possible embodiment of the first aspect of the present application in combination with the first aspect, the emptying device comprises an agitator that is combined with a side wall of the hopper and has an agitator member located in the receiving chamber.

The stirrer is used for stirring the materials in the emptying device so as to mix the materials.

Detailed Description

For liquid or fluid materials, containers are often used to hold the materials for transport, transfer or storage. Such containers usually have an opening for the feed. And the opening may be closed or left open to allow access or discharge of material through the opening, if necessary. To the container that the opening is sealed, it is loaded down with trivial details to take the material on the one hand, simultaneously stores or the condition that the easy material of taking out leaks in the transportation process. For the container with an open opening, the materials are easy to leak during transportation and inconvenient to take and use.

Therefore, there is a need for improvements in such containers to anticipate certain advances in material handling and leakage prevention.

In an example, the inventor proposes a discharging device 100, and the overall structure can be seen in fig. 1, fig. 2 and fig. 3. It has at least two states of use. One is material storage, and the other is material discharge. The discharging device 100 discharges materials through specially-arranged discharging equipment, and sealing equipment is arranged corresponding to the discharging equipment. So, the material is discharged and can be gone on via this discharge apparatus, and seals the operation through sealing device when need not to discharge the material to avoid the material seepage. Based on the design, the feeding and discharging of the discharging device 100 are separated, the convenience of discharging is improved, and meanwhile the problem that the discharging equipment is easy to leak is avoided. In addition, it should be noted that the discharging device 100 provided in the present example can be used for slurry (such as mortar) and solid particles besides liquid materials.

In general, the discharge apparatus 100 mainly includes three parts, i.e., a hopper 101, a discharge device 102, and a stopper 103. The hopper 101 is used as a main body part, and the emptying device 102 and the stop block 103 are both attached to the hopper 101 and cooperate with each other to realize emptying or stop emptying. The various components of the dispensing device 100 will be described in greater detail below.

Hopper 101

Referring to fig. 4, the hopper 101 has a cylindrical structure as a whole. The hopper 101 is a cylinder having a side wall extending from a first end 1012 to a second end 1011. The side walls of the hopper 101 define a receiving chamber 1013 as a space for receiving the material. The shape of the hopper 101 may be adjusted and selected as needed, and is not particularly limited.

The second end 1011 of the hopper 101 is provided with a feed port 1014. Feed port 1014 serves as a passageway and inlet for the addition of material into hopper 101. The inlet can be in the shape of an opening or a cover body is correspondingly arranged. The cover and the second end 1011 of the hopper 101 may be connected by a snap fit, a threaded connection, or the like. In the present example, the feed inlet 1014 provided at the second end 1011 of the hopper 101 is open.

Further, in other examples, the emptying device 200 as shown in fig. 8 comprises an agitator 201. Stirrer 201 is coupled to the side wall of hopper 101 and has a stirring member (not shown) located within receiving chamber 1013. The agitator 201 includes, for example, a guide 2011, a motor 2012, an agitator shaft, and an agitator. The guide 2011 is coupled (e.g., welded or bolted) to the feed port 1014 of the sidewall, i.e., it spans opposite sides of the sidewall. Motor 2012 is coupled to rail 2011 (which may be movably disposed, such as a gear and rack arrangement), and the shaft is coupled to an output shaft of motor 2012 and extends into receiving cavity 1013 of hopper 101. The agitator is coupled to the end of the output shaft distal from the motor 2012. The stirring member may be a blade, such as a flat blade or a helical blade; alternatively, the stirring blade may be an elongated rod.

The side walls of the hopper 101 may be selected according to the type of material it contains, and stainless steel is typically selected. Further, the surface of the stainless steel is subjected to corrosion prevention treatment (such as nickel plating, chrome plating, etc.). Alternatively, the side wall of the hopper 101 is made of plastic, resin, or the like. It may be desirable to increase the wall thickness in order to increase the strength of the hopper 101.

Discharger 102

In the set position, the ejector 102 is shown attached to the first end 1012 of the side wall in FIG. 6. Therefore, in the example having the agitator 201, the agitator 201 and the discharger 102 are respectively located at both ends of the hopper 101.

The discharger 102 serves as a component for discharging the material in the hopper 101, i.e., the discharger 102 provides a channel (a discharge channel 1024 as shown in fig. 6) for discharging the material. Furthermore, the emptying device 102 is further provided with a discharge port (not shown). The discharge channel 1024 and the discharge opening are both in communication with the receiving chamber 1013. Based on this, when the material in the hopper 101 is discharged, the material passes through the discharging channel 1024 in sequence, and then is discharged out of the discharging device 100 through the discharging port.

Since the material is discharged through the hopper 101 and then through the discharger 102, it is obvious that the side wall of the hopper 101 is further provided with a notch 1015 for communicating the discharge passage of the discharger 102 with the receiving cavity 1013 of the hopper 101. The discharge vessel 102 may generally take the form of a cylinder, or an elliptical cylinder, or a prism. Therefore, the shape of the notch 1015 of the sidewall can be adjusted according to the shape of the dispenser 102.

In the example, the discharge device 102 is a cylindrical structure as a whole in terms of appearance, and includes two separate portions. In some examples, the two portions may be referred to as a bevel spout and a single bevel backing block. Wherein, the inclined plane discharge gate is the intercommunication feed cylinder, and inside is opened has the through-hole, and mortar can flow from this through-hole. The outer side of the inclined discharge port is an inclined surface which can be well matched with the stop block 103 for extrusion sealing. The single-bevel backing block may be secured by a clamping member (which will be referred to and described again with reference to a stop member 107) welded to the hopper 101 to act as an outward stop for the stop 103, thereby preventing the stop 103 from being out of position. The bevel discharge port and the single bevel back block are combined together to form a V-shaped groove (or wedge-shaped groove), as shown in FIG. 6. The stop 103 moves up and down in the groove, and when moving downwards, the effect of extruding the discharge port is achieved under the combined action of the fixed unchangeable position or the moving inclined discharge port and the single inclined back block, and the more the discharge port is pressed, the tighter the discharge port is until the discharge port is completely sealed.

The discharge unit 102 has a cylindrical passage. The discharge port of the discharger 102 is provided at one end of the aforementioned passage and communicates with the discharge passage 1024. In one example, the discharge passage 1024 is disposed along an axial direction (e.g., direction B shown in fig. 1) of the discharger 102, and the discharge ports may be disposed along a radial direction of the discharger 102, and the discharge ports intersect and communicate with each other.

In addition, to facilitate the discharge of the material, the discharge channel 1024 is lower with respect to the discharge port of the hopper 101. For example, the height of the discharge channel 1024 is lower than or equal to the height of the bottom of the receiving cavity 1013 to allow the material in the receiving cavity 1013 to be completely discharged from the discharge channel 1024. Further, the discharge channel 1024 has an inclined inner surface. The inclination of the inner surface is defined as follows: the discharge channel 1024 includes a proximal end adjacent the hopper 101 and a distal end distal from the hopper 101. Also, for the discharge channel 1024, the height of the proximal end is greater than the height of the distal end relative to the first end 1012 of the hopper 101.

In particular, the discharge opening is defined by an inclined surface. For example, in the vertical direction, the discharge opening includes a slope and a vertical surface. The inclined surface and the vertical surface cooperate to define a wedge-shaped space, which is the discharge opening. For example, the drain opening may in other examples be formed by two inclined surfaces, whereby the cross-section thereof forms a triangle.

The discharge vessel 102 may be formed integrally with the hopper 101, and thus, both may be formed of the same material. Alternatively, in some examples, the discharger 102 is connected to the hopper 101 by bolts. Alternatively, in other examples, the two may also be connected by an adhesive connection or an interference fit.

Stop 103

The stopper 103 is a member that cooperates with the discharger 102 and is configured to block the discharge port of the discharger 102. For example, the stopper 103 is configured to be selectively inserted into or removed from the drain opening. The stopper 103 has an inclined contact surface 1031. The contact surface 1031 can be wedge-shaped to engage the inclined surface in surface contact to close the drain opening. Since the stopper 103 is fitted with the drain hole, when the drain hole is formed by fitting the inclined surface and the vertical surface to each other, the stopper 103 may also be formed by fitting the inclined surface and the vertical surface to each other.

In the present example, the stopper 103 shown in fig. 5 is also composed of a double slope, corresponding to the discharge port structure composed of a double slope. Thus, the discharge opening is defined by two opposing inclined surfaces, and the stopper 103 also has two opposing inclined surfaces for contact. For example, the drain opening and the stopper 103 are fitted by two inclined surfaces 1023 and two contact surfaces 1031 being in surface contact fit. Further, in order to improve the tightness and sealing property of the stopper 103 in cooperation with the discharge opening, the stopper 103 may be made of an elastic material (e.g., an elastic resin, rubber, etc.) as an alternative. Therefore, the stopper 103 can be compressed to shrink and deform, and then return to the shape when released. Thus, the stopper 103 can be inserted into the discharge opening in an interference fit manner, so that the discharge opening is tightly closed.

Generally, the surface (inclined surface or vertical surface) of the discharge opening is rough, and the surface of the stopper 103 is also rough, so that there is a relatively large friction force therebetween. When the stopper 103 is inserted into the discharging opening of the discharging device 102, the stopper and the discharging opening can keep a relatively stable relative position, so that the state of blocking the discharging opening is kept. Further, since the drain opening and the stopper 103 are wedge-shaped structures, when the stopper 103 is partially disengaged from the drain opening, it may be impacted by the discharged material to undesirably change the posture thereof. With this in mind, in some examples, the discharge apparatus 100 further includes a stopper 107 disposed adjacent to the discharge vessel 102. The stoppers 107 provide restraint on both sides of the discharge opening so that the stopper 103 is restrained from being inserted into or removed from the discharge opening in a certain direction (direction a shown in fig. 1). In other examples, the stopper may be configured to be inserted into the discharge opening of the discharger in the E direction. And it will be appreciated that in such an example, the attitude of the drain is adjusted accordingly with respect to the arrangement of fig. 1, e.g., rotated in the axial direction to change the orientation of the drain (the drain is oriented in direction a in fig. 1, while the change is oriented in direction E toward the rear drain).

For the example where the discharger 102 is a quadrangular prism, when the discharge opening is a through hole penetrating the quadrangular prism and does not intercept the quadrangular prism, the peripheral wall defining the through hole may constitute the above-described stopper 107. In other examples, referring to fig. 6, the discharge vessel 102 takes the form of a cylindrical arrangement having two portions that are broken and mated with each other. Since the two baffles are separate parts, they are fixed separately. For example, the discharger 102 includes a first stopper 1021 and a second stopper 1022. The two blocking bodies are arranged in a manner that the inclined surfaces 1023 are opposite to each other, the second blocking body 1022 is connected with the hopper 101, and the first blocking body 1021 is connected with the limiting member 107.

In cooperation, the limiting member 107 is a C-shaped member or a U-shaped member (see fig. 1 and 2). Both free ends of the retaining member 107 are coupled to the outer surface of the sidewall of the hopper 101, and both portions of the cylindrical (in terms of the outer shape of the discharger) discharger 102 are coupled to the retaining members 107, respectively. In this manner, the stopper 107 passes through both sides of the discharge opening of the discharger 102, and when the stopper 103 is completely inserted into the discharge opening of the discharger 102 or during the detachment of the stopper 103 from the discharge opening, it can be moved with maintaining the posture (e.g., vertically) without moving in other directions (e.g., horizontally, E direction shown in fig. 1). The stopper 107 is a high-strength block, the front end of which is welded to the barrel/hopper 101 and is also connected to the stopper 103. It can provide a back force that prevents the stop 103 from moving outward due to the extrusion of materials such as mortar, resulting in a long lasting seal for a desired period of time.

In addition, there are various options for the manner of operation of the stopper 103, which is achieved by manual operation. I.e. by manually inserting the stopper 103 into the discharge opening or manually removing it. Of course, the stop 103 can also be electrically controlled, taking into account the accuracy and repeatability of the manual operation. Namely, the control is carried out through the cooperation of a mechanical structure and an electronic component. For example, the discharging device 100 is provided with a telescopic device such as a hydraulic cylinder. The hydraulic cylinder faces the discharge opening of the discharger 102. The telescopic motion direction of the piston rod is also opposite to/towards the discharging hole, and the stop block 103 is connected at the tail end of the piston rod. When the hydraulic cylinder works, the piston rod moves in a telescopic way to drive the stop block 103 to move so as to correspondingly insert into the discharging hole or separate from the discharging hole.

Alternatively, the discharging device 100 is provided with an electrically-driven pusher 104 (electric pusher) as shown in FIG. 7. Two ends of the push rod 104 are hinged with the stop block 103 and the side wall of the hopper 101. For example, the push rod 104 has two ends with flat heads and through holes. The stopper 103 is provided with a U-shaped engaging lug 1032, and the second end 1011 (outer wall) of the hopper 101 is also provided with a U-shaped rotating lug 1061 (welded). The flat head is inserted between the two lug arms of the rotating lug 1061 and the connecting lug 1032 and is connected through a stud bolt (both ends are provided with threads, the middle is provided with a smooth screw rod, and the lug arms are provided with connecting holes 1033) or a pin shaft. Therefore, the rotation lug 1061, the push rod 104 and the stopper 103 disposed at the second end 1011 of the hopper 101 form a link mechanism, and the stopper 103 can be moved by driving the push rod 104, that is, the push rod 104 can be operated by an electric machine to drive the stopper 103, so that the stopper 103 is inserted into or separated from the discharge port. The motor 2012 therein may be provided as a motor cooperating with the push rod 104, which is used to operate the push rod to drive the stopper 103. Since the stopper 103 is provided with a double inclined plane in some examples, and the discharging device 102 also has two inclined planes matched with the stopper, by means of the inclined plane structure of the discharging port of the discharging device 102, when the electric pushing rod 104 pushes, the two inclined planes are engaged with each other, the more the two inclined planes extend (the more downwards), the more tightly the discharging port is pressed until the discharging port is completely sealed, and water is not leaked.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
