Description

Technical Field

[0001] The utility model relates to the technical field of lunar mining, in particular to a soil collection device for lunar environment. Background Art

[0002] With the continuous development of human society, the living space of humans is also constantly expanding. The moon is the closest planet to the earth and is rich in mineral resources. In the future construction of the moon, after the rocks on the lunar surface are broken, due to the characteristics of low gravity and vacuum in the lunar environment, how to collect the soil from the lunar surface has become a major problem. In this context, it is of great significance to construct a test device for simulating and studying the vertical collection and slag lifting technology in the lunar environment. Content of the Utility Model

[0003] In order to solve the above technical problems, the utility model specifically adopts the following technical solutions.

[0004] Design a soil collection device for lunar environment, including a screw feeder. An impact collection mechanism is connected to the slag inlet of the screw feeder through an angle adjustment mechanism. A receiving bin is connected to the slag discharge port of the screw feeder. After the impact collection mechanism repeatedly impacts and collects the soil surface, it enters the screw feeder through the angle adjustment mechanism and is conveyed.

[0005] The impact collection mechanism includes a fixed part and a movable part movably sleeved in the fixed part. The movable part reciprocates along the fixed part driven by a motion component. A check component is arranged in the front section of the movable part. The check component includes a first check fan blade and a second check fan blade respectively connected through a first fan blade rotating shaft and a second fan blade rotating shaft, a rotating shaft arranged between the first fan blade rotating shaft and the second fan blade rotating shaft, and a torsion spring arranged on the rotating shaft.

[0006] Preferably, the front section and the rear section of the movable part are connected by threads.

[0007] Preferably, a cross-shaped impact head is arranged at the inlet of the front section of the movable part, and the cross section of the impact head is triangular.

[0008] Preferably, the motion component includes a motor arranged in the fixed part, a second bevel gear arranged on the output shaft of the motor, a first bevel gear meshing with the second bevel gear, a crank key-connected with the first bevel gear, and a connecting rod hinged to one end of the crank. The motor is fixed on a fixed base. The connecting rod is connected to the rear section of the movable part. The first bevel gear is fixed on the inner wall of the front section of the movable part through a rotating shaft.

[0009] Preferably, the angle adjustment mechanism includes a flexible connecting member, a first inflatable member and a second inflatable member provided on both sides of the flexible connecting member. The outlet of the impact collection assembly is connected to the slag inlet of the spiral feeder through the flexible connecting member. An air tank, an airbag, and an air pump respectively connected to the air tank and the airbag are provided in the first inflatable member and the second inflatable member.

[0010] Preferably, the spiral feeder includes a housing, a conveying motor installed at the upper end of the housing, a spiral rod rotatably provided in the housing, and spiral blades provided on the spiral rod. Both ends of the spiral rod are rotatably connected to the housing through an upper bearing and a lower bearing, and the end faces of the upper bearing and the lower bearing are respectively sealed with an upper bearing end cover and a lower bearing end cover. One end of the upper bearing end cover is connected to the housing to play a sealing role, and the other end is made into a platform with a through hole for facilitating the installation of the conveying motor.

[0011] The beneficial effects of the present utility model are as follows:

[0012] The present utility model uses the impact collection mechanism to repeatedly impact on the soil surface, collect the soil into the soil bin of the movable part. The soil continuously accumulates in the bin and finally enters the spiral feeder along the flexible connecting member. It is transported by the spiral blades and finally discharged from the slag outlet to the receiving bin for collection. Moreover, the movable part in the impact collection mechanism is driven by the motion component to make a reciprocating telescopic motion along the fixed part, thereby realizing the collection and impact of the soil. Specifically, a crank and connecting rod mechanism is used to drive the movable part of the impact collection mechanism to move, and the impact head is used to repeatedly impact on the soil surface. Under the action of the torsion spring, the impact force of the soil pushes open the first check fan blade and the second check fan blade, and brings the soil into the interior of the impact collection mechanism. The soil continuously accumulates in the bin of the impact collection mechanism with the impact. When the soil reaches a certain height, it is sent into the spiral feeder by the flexible connecting member. Due to the low gravity environment on the moon, the soil is more likely to rise with the spiral feeder to the slag outlet and be discharged. During this process, the first inflatable member and the second inflatable member can expand or contract with each other to change the angle of the impact collection mechanism relative to the spiral feeder, thereby adjusting the angle when the impact collection mechanism imports and collects the soil, and the angle when the impact collection mechanism transports the slag to the slag inlet of the spiral feeder, which is more conducive to the collection or transportation of the soil.

[0023] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0024] Embodiment 1

[0025] A soil collection device for the lunar environment, as Figures 1 to 9 shown, includes a screw feeder 9. An impact collection mechanism 1 is connected to the feed inlet 941 of the screw feeder 9 through an angle adjustment mechanism 5. A receiving bin 103 is connected to the slag discharge port 102 of the screw feeder 9. After the impact collection mechanism 1 repeatedly impacts and collects the soil surface, it enters the screw feeder 9 and is conveyed;

[0026] The impact collection mechanism 1 includes a fixed component 17 and a movable component 11 movably sleeved within the fixed component 17. The movable component 11 reciprocates along the fixed component 17 driven by a motion component. A check component is provided within the front section of the movable component 11. The check component includes a first check fan blade 111 and a second check fan blade 112 respectively connected by a first fan blade rotating shaft 116 and a second fan blade rotating shaft 118, a rotating shaft 119 provided between the first fan blade rotating shaft 116 and the second fan blade rotating shaft 118, and a torsion spring 117 provided on the rotating shaft 119.

[0027] The movable component 11 has a front and rear two-section structure connected by threads, ensuring the flatness and coaxiality of the contact transition surface, thus facilitating the disassembly, assembly, and maintenance of the check component inside the movable component 11.

[0028] In order to impact large unbroken soil blocks into small soil blocks for easy soil collection and at the same time protect the first fan blade rotating shaft 111, the second fan blade rotating shaft 112, and the rotating shaft, a cross-shaped impact head 113 is provided at the inlet of the front section of the movable component 11, and the cross-section of the impact head 113 is triangular.

[0029] The motion component includes a motor 16 provided within the fixed component 17, a second bevel gear 15 provided on the output shaft of the motor 16, a first bevel gear 14 meshing with the second bevel gear 15, a crank 13 key-connected to the first bevel gear 14, and a connecting rod 12 hinged to one end of the crank 13. The motor 16 is fixed on a fixed base 171, the connecting rod 12 is connected to the rear section of the movable component 11, and the first bevel gear 14 is fixed on the inner wall of the front section of the movable component 11 through a rotating shaft. Specifically, a front fixed bracket 172 is provided at the top within the front section of the movable component 11, and a rear fixed bracket 173 is fixed on the rear wall within the front section of the movable component 11. Both ends of the rotating shaft are respectively provided on the front fixed bracket 172 and the rear fixed bracket 173. The meshing of the second bevel gear 15 and the first bevel gear 14 at a 90° angle changes the transmission direction, enabling the motor 16 to be axially arranged along the impact collection mechanism 1, saving installation space, and the motion component drives the movable component 11 to reciprocate along the fixed component 17.

[0030] A plurality of through holes evenly distributed are provided on the crank 13, and the first bevel gear 14 is connected to the through holes on the crank 13 through a connecting shaft to adjust the length of the crank 13, thereby expanding the adjustment range of the impact frequency.

[0031] The angle adjustment mechanism 5 includes a flexible connecting member 52, and a first inflatable member 51 and a second inflatable member 53 provided on both sides of the flexible connecting member 52. An air tank, an airbag, and an air pump respectively connected to the air tank and the airbag are provided in the first inflatable member 51 and the second inflatable member 53. By contracting the first inflatable member 51 and expanding the second inflatable member 53, or expanding the first inflatable member 51 and contracting the second inflatable member 53, the angle between the impact collection mechanism 1 and the screw feeder 9 is changed.

[0032] The screw feeder 9 includes a housing 94, a conveying motor 101 installed at the upper end of the housing 94, a screw rod 95 rotatably provided in the housing 94, and screw blades provided on the screw rod 95. Both ends of the screw rod 95 are rotatably connected to the housing 94 through an upper bearing and a lower bearing 91. The end faces of the upper bearing and the lower bearing 91 are respectively sealed with an upper bearing end cover and a lower bearing end cover. The upper bearing end cover is a non-standard part, one end of which is connected to the housing 94 for sealing, and the other end is made into a platform with a through hole for facilitating the installation of the conveying motor 101. A baffle 942 is provided on one side of the screw feeder 9 at the slag inlet 941. The baffle 942 structure is adopted at the slag inlet 941 of the housing 94, which can prevent the soil from falling from the slag inlet 941 to the flexible connecting member 52 during the vertical conveying process, affecting the slag discharge efficiency. After the soil enters the slag inlet 941, it enters the bottom of the screw feeder 9 along the channel of the slag inlet 941, and then is transported to the slag discharge port 102 through the screw feeder 9. During the rising process of the soil, the whole pipeline is in a continuous sealed state to prevent the soil from falling into the slag inlet 941, greatly improving the transportation performance.

[0033] When the utility model works, the screw feeder 9 and the motor 16 are started, so as to drive the second bevel gear 15 to engage and rotate the first bevel gear 14, and further drive the crank 13 and the connecting rod 12 to drive the movable member 11 to perform a telescopic reciprocating motion along the fixed member 17, so that the impact head 113 impacts the soil and impacts the large soil blocks into small soil blocks. Under the action of the torsion spring 117, the impact force opens the first check fan blade 111 and the second check fan blade 112. When no soil enters the impact collection mechanism 1, the torsion spring 117 resets, and the first check fan blade 111 and the second check fan blade 112 block the inlet of the movable member 11 to prevent the soil in the impact collection mechanism 1 from falling.

[0034] Finally, the soil enters the interior of the screw feeder 9 along the channel of the slag inlet 941 of the screw feeder 9, and is then transported to the slag discharge port 102 by the screw feeder 9. During the above process, the inert gas in the tank is pumped into the airbag by the air pump, so that the first inflatable member 51 contracts and the second inflatable member 53 expands, or the first inflatable member 51 expands and the second inflatable member 53 contracts, thereby changing the angle of the impact collection mechanism 1 relative to the screw feeder 9. Furthermore, the angle of the impact collection mechanism 1 when collecting soil at the slag inlet 941 and the angle of the impact collection mechanism 1 when transporting the slag to the slag inlet of the screw feeder 9 can be adjusted, which is more conducive to the collection or transportation of the soil.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
