Abstract
Description
Technical Field
[0001] The utility model relates to a sand falling structure of a continuous sand mixer. Background Art
[0002] With the development of society, the continuous research and development of various scientific and technological fields, and the emergence of various mechanical equipment, people's daily lives have become more convenient and work efficiency has been improved. In the manufacturing process of most equipment, some parts need to be cast and molded, and then machined into specific parts. The traditional casting method is sand casting, which has high requirements for molding sand and requires preliminary sand molding work. After the sand material is formed into casting sand by adding molding sand binders, it needs to be transported to the mold cavity for filling. However, the current filling points are all fixed, resulting in the casting sand piling up into a conical structure after falling. That is, this sand falling process requires workers to push and level the mold at the same time, which is inefficient and labor-intensive, and needs to be improved urgently. Utility Model Content
[0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a sand-falling structure for a continuous sand mixer, which is not only structurally reasonable but also highly efficient and convenient.
[0004] In order to solve the above technical problems, the technical solution of the utility model is: a sand falling structure of a continuous sand mixer, comprising a sand falling channel arranged above the mold cavity, a sand falling port being opened at the lower end of the sand falling channel and a sand falling hose being connected to the sand falling port, a collar being arranged on the outer surface of the output end of the sand falling hose and being fixedly connected thereto, a swinging rod being rotatably connected to the collar for swinging the sand falling hose.
[0005] Furthermore, a fixing rod is radially fixedly connected to the collar, a rotating handle is coaxially rotatably connected to the outside of the fixing rod, and the outer end of the rotating handle is hinged to a hinge seat fixedly connected to the end of the swing rod.
[0006] Furthermore, the sand falling channel includes a conveying pipe, in which the foundry sand is conveyed via an auger.
[0007] Furthermore, a vertical connecting pipe is fixedly provided at the sand falling port, and the sand falling hose is sleeved on the connecting pipe and fastened by a hoop.
[0008] Furthermore, a hanging seat is fixedly provided on the conveying pipe, a hook is fixedly provided on the outer end of the collar, and a hanging groove is provided on the hanging seat for cooperating with the hook.
[0009] Furthermore, the falling sand hose is a corrugated hose.
[0010] Compared with the prior art, the utility model has the following beneficial effects: through the cooperation of the sand falling hose and the swing arm, the process of evenly laying the casting sand is completed simultaneously during the sand falling process, which saves time and labor and achieves more efficient work. At the same time, it is convenient to store and saves space.
[0011] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0017] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description.
[0018] like Figures 1 to 4 As shown, a sand-falling structure of a continuous sand mixer includes a sand-falling channel 2 arranged above a mold cavity 1, a sand-falling port 3 is opened at the lower end of the sand-falling channel and a sand-falling hose 4 is connected to the sand-falling port, a collar 5 is arranged on the outer surface of the output end of the sand-falling hose and fixedly connected, a swing rod 6 for swinging the sand-falling hose is rotatably connected to the collar, and a handle 17 is fixedly provided at the end of the swing rod.
[0019] In the embodiment of the present invention, a fixing rod 7 is radially fixed to the collar, a rotating handle 8 is coaxially connected to the outside of the fixing rod, and the outer end of the rotating handle is hinged to a hinge seat 9 fixed to the end of the swing rod.
[0020] In the embodiment of the present invention, the sand falling channel includes a conveying pipe 10 , in which the foundry sand is conveyed via an auger 11 .
[0021] In the embodiment of the present invention, a vertical connecting pipe 12 is fixedly provided at the sand falling port, and the sand falling hose is sleeved on the connecting pipe and fastened by a hoop 13 .
[0022] In the embodiment of the present invention, a hanging seat 14 is fixed on the delivery pipe, a hook 15 is fixed on the outer end of the collar, and a hanging groove 16 for cooperating with the hook is provided on the hanging seat.
[0023] In the embodiment of the present utility model, the falling sand hose is a corrugated hose.
[0024] The working principle of the embodiment of the utility model is as follows: when filling the mold cavity with foundry sand, the swing arm is pushed upward to disengage the hook from the hanging slot, causing the sand drop hose to swing downward. The auger is then activated to convey the foundry sand. The foundry sand enters the sand drop hose through the sand drop port. The worker then holds the swing arm to drive the sand drop hose to evenly distribute the foundry sand in different directions within the mold cavity, eliminating the need for subsequent sand removal. This ensures uniform distribution during conveying, making the process more efficient and stable. After completion, the auger is closed, the swing arm is raised, and the hook is reattached to the hanging slot for storage, saving space.
[0025] The present invention is not limited to the above-mentioned preferred embodiment. Anyone can derive other forms of continuous sand mixer sand shakeout structures based on the inspiration of the present invention. All equivalent changes and modifications made within the scope of the patent application of the present invention shall fall within the scope of the present invention.
