Problems solved by technology

Although the current hopper can allow the combination scale to work, it still has the following technical defects: 1. When the combination scale is used to weigh viscous materials, after the material falls from the hopper, more materials will adhere to the bucket body. The top of the discharge port and the hopper door, which causes waste of materials, increases the production cost, and affects the quality of the packaged materials; 2. The installation and maintenance of the hopper are inconvenient; 3. The material is easier to adhere to the inner wall of the hopper body. This further causes waste of material, and this makes the hopper difficult to clean

Embodiment 1

[0032] like Figure 1 to Figure 8 The shown hopper for the combination scale includes a bucket body 1, a bucket door 2, a suspension mechanism, a driving device and a push-pull rod 3; The pull rod 3 is driven and connected, the push-pull rod 3 is driven and connected with the bucket door 2, and the bucket door 2 is attached to the discharge port 101 at the bottom of the bucket body 1; when the driving device drives the push-pull rod 3 to move forward and backward along a straight line, the bucket door 2 correspondingly The outer edge of the discharge opening 101 of the body 1 slides open or closes.

[0033] like figure 1 , figure 2 , image 3 and Figure 8 As shown, the suspension mechanism includes a suspension frame 4 and a suspension nail 5, the lower end of the suspension frame 4 is fixed on the installation frame, and the upper end of the suspension frame 4 is provided with a suspension hole 401 matched with the suspension nail 5; One end of the nail 5 is fixedly co...

Embodiment 2

[0043] This hopper that is used for combination balance is with embodiment 1 except following technical characteristics: as Figure 9 As shown, the hopper for the combination scale also includes 2 articulated shafts and 2 articulated frames, the 2 articulated frames are respectively installed on the two side walls of the bucket body, and the section of the hopper door is in the shape of "凵" , both sides of the upper end of the bucket door are respectively hinged with hinge shafts, the hinge shafts are suspended from the hinge frame, and one side wall of the bucket door is provided with a connecting shaft connected with a push-pull rod. This design can make the installation and movement of the Doumen more stable, and improve the reliability of the Doumen's work.

Embodiment 3

[0045] The hopper used for the combination scale is the same as the embodiment 1 except the following technical features: the hopper door is plate-shaped, and the side of the hopper door is fixedly connected with the driving device.

[0046] The driving device includes a cylinder, the cylinder is fixed on the installation frame, and the piston rod of the cylinder is fixedly connected to one end of the push-pull rod, and the other end of the push-pull rod is fixedly connected to the side of the bucket door.

[0047] The bucket door of this embodiment has a simple structure, is convenient to process and manufacture, and reduces production costs. When working, the piston rod of the cylinder is stretched out to make the bucket door move forward in a straight line. During the straight forward movement of the bucket door, the front lower end of the bucket body can scrape off the materials adhering to the bucket door, which can also play a role. Avoid wasting materials.

Abstract

The invention discloses a hopper for a combined weighing scale. The hopper comprises a hopper body, a hopper door, a suspension mechanism, a driving device and a push-pull rod. The hopper body is installed on an installation frame of the combined weighing scale through the suspension mechanism, the driving device is in driving connection with the push-pull rod, the push-pull rod is in driving connection with the hopper door, and the hopper door is attached to and arranged at a discharging port in the lower portion of the hopper body. When the driving device drives the push-pull rod to move back and forth along a straight line, the hopper door is correspondingly opened or closed along the outer edge of the discharging port of the hopper body in a sliding mode. According to the hopper for the combined weighing scale, materials attached to the upper face of the hopper door can be scraped down by the hopper body, waste of the materials is avoided, meanwhile, the weighing accuracy of the combined weighing scale is ensured, and the packaging quality is ensured.

Description

technical field [0001] The invention relates to a combined scale equipment technology, in particular to a hopper used for a combined scale. Background technique [0002] The hopper is one of the indispensable parts in the combination scale. The current hopper is mainly composed of a bucket body and a bucket door. The bucket door is hinged at the discharge opening of the bucket body, and the discharge opening of the bucket body is closed by swinging the bucket door up and down. Although the current hopper can allow the combination scale to work, it still has the following technical defects: 1. When the combination scale is used to weigh viscous materials, after the material falls from the hopper, more materials will adhere to the bucket body. The top of the discharge port and the hopper door, which causes waste of materials, increases the production cost, and affects the quality of the packaged materials; 2. The installation and maintenance of the hopper are inconvenient; 3....
