Description

Technical Field

[0001] The utility model relates to the technical field of grain storage, in particular to a grain silo ventilation pipe recovery unit and a grain silo ventilation pipe layout recovery combined unit adopting the recovery unit. Background Art

[0002] Mechanical ventilation for grain storage uses a fan to force the outside air into the grain pile, or to forcefully suck out the air in the grain pile for gas exchange to achieve the purpose of cooling and dissipating moisture. During grain storage, grain moisture, respiration, and microbial action can cause local or multi-point heating of grain. In order to solve the problem of local or multi-point heating, an auxiliary ventilation pipe of a certain depth is usually driven into the grain pile, and the auxiliary ventilation pipe is used to carry out targeted ventilation and cooling of the heating points. However, this auxiliary ventilation pipe needs to be pulled out before the grain is shipped out of the warehouse.

The pipe pulling buckle at the end of the lifting rope is connected to the top of the ventilation pipe, and the ventilation pipe is pulled out of the grain pile for recovery. This method of connecting the top of the ventilation pipe for pulling out the pipe still has the disadvantages of being difficult to pull out the pipe and low efficiency for the ventilation pipe buried deeper.

[0030] The utility model will be further described below in conjunction with the accompanying drawings.

[0031] Example 1

[0032] See also Figure 1-4 , a grain silo ventilation pipe recovery unit, which includes a recovery mechanism.

[0033] The recovery mechanism includes a base 1, a column 2 connected to the base 1, and a boom 3 arranged above the column 2. An electric winch 21 is installed at one end of the boom 3, a plurality of guide wheels 31 are arranged on the boom 3, a suspension rope 22 is wound around the electric winch 21, and the suspension rope 22 is arranged along the boom 3 and bypasses the guide wheels 31.

[0034] The end of the lifting rope 22 is connected to an auxiliary mechanism, which includes a connector 4 and at least one auxiliary tube 5. The bottom end of one auxiliary tube 5 can be aligned and connected with the top end of another auxiliary tube 5. The top of the uppermost auxiliary tube 5 is connected to the lifting rope 22 through the connector 4, and the bottom of the lowermost auxiliary tube 5 is provided with a hook 6.

[0035] When the above structure is used to recycle the ventilation pipes in the grain silo, the recovery mechanism is placed near the ventilation pipes 9 to be recovered on the grain surface. A certain number of auxiliary pipes 5 are selected according to the length of the auxiliary pipes 5 and the depth of the ventilation pipes 9 buried in the grain pile. Currently, the length of the auxiliary pipes 5 is 1 to 1.5 meters and the outer diameter is 4 to 5 centimeters. Figure 1 and Figure 4 , insert the auxiliary tubes 5 one by one into the ventilation pipe 9 in the grain pile, and connect them end to end in sequence. At the same time, prepare an industrial endoscope, which includes a control display host 7 and an imaging probe 71 electrically connected to the control display host 7. Put the imaging probe 71 into the lumen of the ventilation pipe 9 to the bottom of the ventilation pipe 9, and then observe through the industrial endoscope whether the hook 6 of the lowest auxiliary tube 5 can hook to the bottom of the ventilation pipe 9. After that, the uppermost auxiliary tube 5 applies force to hook the hook 6 of the lowermost auxiliary tube 5 on the bottom end of the ventilation pipe 9, and observe and confirm through the industrial endoscope. In addition, it should be noted that the top of the uppermost auxiliary tube 5 is exposed to the ventilation pipe 9 as much as possible, so that the uppermost auxiliary tube 5 can be connected to the suspension rope 22 through the connector 4, and it is convenient for the uppermost auxiliary tube 5 to apply force. Then start the electric winch 21 of the recovery mechanism, pull up and reel the suspension rope 22, and the suspension rope 22 is pulled up and out of the grain surface by the hook 6 of the auxiliary tube 5.

[0036] When the ventilation pipe 9 is pulled up to a certain height and the entire ventilation pipe 9 at the top is completely exposed from the grain surface, the lifting rope 22 can be separated from the auxiliary pipe 5, and the ventilation pipe 9 exposed from the grain surface and the auxiliary pipe 5 at the corresponding position can be removed in turn to recover the ventilation pipe 9. After that, the new uppermost auxiliary pipe 5 is connected to the lifting rope 22 through the connector 4, and the electric winch 21 of the recovery mechanism is started. The above steps are repeated to remove and recover the ventilation pipe 9 exposed from the grain surface and the auxiliary pipe 5 at the corresponding position, until all the ventilation pipes 9 are pulled out of the grain surface and recovered.

[0037] Further, specific reference Figure 2 and Figure 3 In this embodiment, the auxiliary tube 5 is made of metal material, specifically a hollow through-tube structure, with a tubular butt joint 51 at the top. The inner wall of the tubular butt joint 51 has a thread, and the outer wall of the bottom end of the auxiliary tube 5 has a thread. The bottom end of one auxiliary tube 5 can be inserted into and threadedly connected to the tubular butt joint 51 at the top of another auxiliary tube 5, so that the two auxiliary tubes 5 are aligned and connected by threads.

[0038] In addition, in this embodiment, the connector 4 has a lifting ring 41 at one end and a rod 42 at the other end. The outer wall of the rod 42 has a thread. The rod 42 of the connector 4 can be inserted into and threadedly connected to the tubular docking joint 51 at the top of the auxiliary tube 5. The lifting ring 41 of the connector 4 can be connected to the end of the lifting rope 22. The connector 4 with a threaded structure facilitates quick and firm connection with the auxiliary tube 5.

[0039] Further, specific reference Figure 1 A hook 220 is also provided at the end of the lifting rope 22, and the connecting head 4 can be hung on the hook 220 by a lifting ring 41. Through the hook 220 and the connecting head 4, the lifting rope 22 and the auxiliary pipe 5 can be quickly connected and disconnected.

[0040] In this embodiment, the hook 6 can be directly welded to the bottom end of one of the auxiliary tubes 5 (not shown in the figure), and the auxiliary tube 5 is always placed at the bottom when in use. Figure 2 and Figure 3 As shown, the auxiliary mechanism further includes a hook claw connector 61, the hook claw connector 61 has a tubular connector portion 62, the inner wall of the tubular connector portion 62 has threads and can be threadedly connected to the bottom end of the auxiliary tube 5, and the hook claw 6 is arranged on the outer wall of the tubular connector portion 62. In the above structure, the hook claw 6 is assembled on the auxiliary tube 5 through the hook claw connector 61, which improves the convenience of use.

[0041] Furthermore, the column 2 of the recovery mechanism of the present embodiment includes a column portion 24 and a rotating column portion 25 rotatably arranged at the top of the column portion 24. The bottom of the column portion 24 is connected to the base 1, and the arm 3 is connected to the rotating column portion 25. The bottom end of the rotating column portion 25 is rotatably sleeved on the top of the column portion 24. A locking bolt 23 passes through the bottom end of the rotating column portion 25 and is tightened against the column portion 24 to position and connect the column portion 24 and the rotating column portion 25. The bottom end side wall of the rotating column portion 25 has a threaded hole corresponding to the locking bolt 23. During use, the locking bolt 23 can be loosened to rotate the rotating column portion 25 and the arm 3 thereon, and the locking bolt 23 can be tightened after adjusting the position of the suspension rope 22, thereby avoiding moving the recovery mechanism and improving the convenience of operation.

[0042] Example 2

[0043] The granary ventilation pipe recovery unit of this embodiment is different from that of Embodiment 1 in that:

[0044] Specific reference Figure 5 The control and display host 7 of the industrial endoscope is installed on the upper part of the column 2, so that the staff can check the situation at any time.

[0045] Specific reference Figures 6 to 9The imaging probe 71 of the industrial endoscope is installed on the tubular joint portion 62 of the hook claw connector 61 through an external rubber member 8. The external rubber member 8 has a first annular ring portion 81 and a second annular ring portion 82. The outer wall of the first annular ring portion 81 and the outer wall of the second annular ring portion 82 are connected. The imaging probe 71 is inserted into the second annular ring portion 82 of the external rubber member 8. The external rubber member 8 is sleeved on the tubular joint portion 62 of the hook claw connector 61 by the first annular ring portion 81, so that the imaging probe 71 is arranged near the bottom of the lowest auxiliary tube 5.

[0046] When this embodiment is in use, the imaging probe 71 is installed on the hook connector 61 through an external rubber part, so that the imaging probe 71 automatically descends and rises along with the auxiliary tube 5 at the bottom, and there is no need to manually lower and pull back the imaging probe 71, thereby further improving the convenience of operation.

The deep sampling machine includes a sampling machine body 93 and a deep sampling pipe 94 connected to the sampling machine body 93 through a pipeline. The deep sampling pipe 94 is formed by connecting a plurality of auxiliary pipes 5 in sequence. The bottom end of the deep sampling pipe 94 is connected to a sampling pipe head 95. Fig.10 and Fig.12 .

[0050] When the granary ventilation pipe laying and recovery combined unit of this embodiment is in use, the auxiliary pipe 5 of the granary ventilation pipe recovery unit of embodiment 1 can be used to assemble the deep sampling pipe 94 of the granary ventilation pipe laying unit, such as Fig.10 and Fig.11 , install the ventilation pipe 9 on the vibration frame 90 through the pipe holder 91, start the vibration motor 92, and the operator holds the vibration frame 90 to vibrate and sink the ventilation pipe 9. At the same time, the deep sampling tube 94 is inserted into the ventilation pipe 9 from the top of the ventilation pipe 9, and the grain in the ventilation pipe 9 is sucked out through the deep sampling tube 94, reducing the resistance of grain particles to the ventilation pipe 9, so that the ventilation pipe 9 can sink quickly. After the top ventilation pipe 9 sinks to a certain depth, disassemble the pipe holder 91, connect a new ventilation pipe 9 and connect the pipe holder 91, and continue to sink while vibrating. At the same time, increase the number of auxiliary pipes 5, assemble a deep sampling tube 94 of corresponding length, and effectively suck out the grain particles in the ventilation pipe 9.
