DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the protection scope of the present invention.

[0021] like Figure 1 and Figure 2 As shown together, a transfer machine closing device includes an end bracket 4 and a protective net installed on one side of the end bracket 4. The protective net is located on the unloading side of the transfer machine 3. The protective net is provided with an insertion space for the head of the scraper to pass through and a pushing space for avoiding the movement of the scraper and / or the end bracket 4. The insertion space is adjacent to the pushing space and is connected. The protective net closes the unloading side of the transfer machine 3 to prevent people from mistakenly entering the transfer machine 3 and avoiding safety accidents. At the same time, since the scraper and the end bracket 4 do not move at the same time, the pushing space of the protective net can avoid interference between the scraper and the protective net during the movement of the scraper and the end bracket 4, resulting in damage to the protective net.

[0022] Specifically, Figure 1 As shown, the scraper includes a first scraper 1 and a second scraper 2, and the protective net includes a first protective net 5 and a second protective net 6 that are spaced apart. The gap between the first protective net 5 and the second protective net 6 forms an avoidance for the passage 31 and will not affect the walking of operators during the production process.

[0023] The extension space and the push space of the first protection net 5 are defined as the first extension space 51 and the first push space 52, and the extension space and the push space of the second protection net 6 are defined as the second extension space 61 and the second push space 62. The extension space and the push space are both located at the lower end of the protection net. The head of the first scraper 1 passes through the first extension space 51 of the first protection net 5 to connect with the transfer machine 3, and the head of the second scraper 2 passes through the second extension space 61 of the second protection net 6 to connect with the transfer machine 3.

[0024] Among them, the definition Figure 1 The left side is the front, and the right side is the back. The first push space 52 is located in the front of the first extension space 51, and the second push space 62 is located in the back of the second extension space 61. When the scraper is pushed, the first scraper 1, the end bracket 4 and the second scraper 2 are pushed forward in sequence, that is, the first scraper 1 is first pushed forward by a step, and the head of the first scraper 1 moves to the position of the first push space 52; the end bracket 4 is pushed forward by a step, and the second protection net 6 is partially moved to the position of the second push space 62; the second scraper 2 is finally pushed forward by a step, and during this pushing process, the scraper will not cause damage to the protection net.

[0025] In this embodiment, the horizontal length of the pushing space is a pushing step of the scraper. Under the condition that the protective net is not damaged during the pushing process, the pushing space is reduced as much as possible to ensure the closure of the unloading place of the transfer machine 3.

[0026] like Figure 2 and Figure 3 As shown in the figure, the protective net is composed of a plurality of single-piece protective nets of different sizes, which is convenient for processing. Specifically, the single-piece protective net includes a protective net body 74, a square tube 73, a chain 72 and a shackle 71. The upper and lower sides of the protective net body 74 are respectively fixed with square tubes 73, and the square tubes 73 are connected to the shackle 71 through the chain 72. The shackles 71 on the upper and lower sides are respectively installed on the bracket top beam 41 and the bracket base 42 of the end bracket 4, and the protective net can be tightened.

[0027] The length of the chain 72 can be customized according to the height of the end bracket 4, and the protective net body 74 is a 304 stainless steel wire rope net, which is not easy to damage and has a certain amount of elasticity. It can adapt to changes in the height of the end bracket 4. It also has the advantages of light weight and easy installation and maintenance.

[0028] The transfer machine closing device of the utility model installs a protective net on the unloading side of the transfer machine. The protective net closes the unloading side of the transfer machine, which can effectively prevent people from mistakenly entering the transfer machine and avoid safety accidents. At the same time, the pushing space and extension space set on the protective net can avoid interference between the scraper and the protective net during the pushing process of the scraper and the end bracket, which may cause damage to the protective net.
