Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, specifically a drilling sampling device for forestry tree survey. Background Technology

[0002] Forestry surveys can monitor the growth and changes of trees in forestry areas. During forestry surveys, in order to better test the soil conditions, a drill bit is usually inserted into the soil and the friction between the drill bit and the soil is used to bring out soil samples at a certain depth so as to observe the soil conditions near the trees and facilitate the subsequent protection of the trees for normal growth.

[0003] Chinese patent CN215985278U discloses a drilling and sampling device for forestry tree survey. The device facilitates sampling by rotating the handle to drive the first movable rod, allowing staff to take samples in any soil layer. This provides greater freedom in sampling, facilitates observation of the soil conditions around the trees, and helps staff to develop maintenance plans for the trees, thereby ensuring their normal growth.

[0004] However, commercially available soil sampling equipment typically requires multiple drive methods to raise, lower, and rotate the drill bit during the sampling process, resulting in wasted power. After sampling, unloading is difficult, affecting the practicality of the equipment. Utility Model Content

[0005] This invention provides a drilling and sampling device for forestry tree surveying to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling and sampling device for forestry tree surveying, comprising a shell and a base plate fixed to the lower end of the shell, and a fixing plate fixed inside the shell near the lower end, the fixing plate having a connecting ring fixed to its lower end; a guide sleeve disposed inside the shell and sliding axially along the shell; a guide rod rotatably mounted inside the upper end of the shell, the lower end of the guide rod extending into the guide sleeve and slidably connected to the guide sleeve; a drill bit fixed to the lower end of the guide sleeve, the drill bit having a sampling chamber near its lower end, the sampling chamber having an annular blade fixed to its lower end, and the drill bit also having a discharge component for discharging soil samples from the sampling chamber; and a transmission component disposed on one side of the shell to cause the guide sleeve to rise and fall, thereby rotating the guide rod.

[0007] As a preferred embodiment of this utility model, the unloading component includes an annular cavity opened at the upper end of the drill bit. A movable sleeve is slidably installed inside the annular cavity. Guide posts are fixed at equal intervals at the lower end of the movable sleeve. The guide posts extend into the material taking chamber and are fitted with pressure plates. A return spring is installed on the outer side of the guide posts between the movable sleeve and the lower end of the annular cavity. The drill bit rises so that the movable sleeve abuts against the connecting ring, causing the movable sleeve to slide towards the annular blade.

[0008] As a preferred technical solution of this utility model, through grooves are provided on both sides of the outer shell, a connecting plate is installed on the upper end of the guide sleeve, the connecting plate is connected to the guide sleeve bearing, and the connecting plate is slidably connected to the through groove. A handle is fixed on one side of the connecting plate through the through groove, and the handle is used to drive the connecting plate to rise and fall.

[0009] As a preferred technical solution of this utility model, the transmission component includes a transmission box fixed to the upper end of the outer shell, a lead screw rotatably mounted between the transmission box and the base plate, and a nut pair adapted to the lead screw fixed to one end of the connecting plate. The connecting plate is raised and lowered so that the nut pair drives the lead screw to rotate.

[0010] As a preferred embodiment of this utility model, the upper ends of the lead screw and guide rod both extend into the transmission box and are equipped with transmission wheels, and a synchronous transmission belt is provided between the two transmission wheels.

[0011] As a preferred embodiment of this utility model, the guide sleeve is a stainless steel component, and the outer side of the outer shell is provided with scale lines.

[0012] Compared with the prior art, this utility model provides a drilling and sampling device for forestry tree surveying, which has the following beneficial effects:

[0013] 1. This drilling and sampling device for forestry tree surveying, through the setting of the transmission component, enables the guide rod to rotate when the connecting plate is raised and lowered, thereby realizing the synchronous raising and lowering and rotation of the drill bit, improving the traditional driving method and reducing the number of power outputs.

[0014] 2. The drilling and sampling device for forestry tree surveying uses a movable sleeve that abuts against a connecting ring, causing the connecting ring to squeeze the movable sleeve. This causes the guide column to push the pressure plate to move, and the pressure plate pushes out the soil sample from inside the sampling chamber, thus facilitating soil unloading.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 5 This utility model discloses a drilling and sampling device for forestry tree survey, including a shell 1 and a base plate 2 fixed to the lower end of the shell 1, and also includes a fixing plate 4, which is fixed inside the shell 1 near the lower end, and a connecting ring 15 is fixed to the lower end of the fixing plate 4.

[0023] The drilling and sampling device for forestry tree survey provided in this embodiment also includes a guide sleeve 5, which is disposed inside the outer shell 1 and slides axially along the inner shell 1. The lower end of the guide sleeve 5 passes through the fixing plate 4 and the connecting ring 15 in sequence. Optionally, a brush is provided inside the fixing plate 4 to clean the soil residue on the surface of the guide sleeve 5. In addition, a guide rod 14 is rotatably installed at the upper end inside the outer shell 1, and the lower end of the guide rod 14 extends into the guide sleeve 5 and slides in connection with the guide sleeve 5. The guide sleeve 5 can be rotated by rotating the guide rod 14.

[0024] To facilitate soil sampling and unloading, the drilling and sampling device for forestry tree survey provided in this embodiment also includes a drill bit 6. The drill bit 6 is fixed to the lower end of the guide sleeve 5, and a sampling chamber 19 is provided near the lower end of the drill bit 6. An annular blade 7 is fixed at the lower end of the sampling chamber 19. The annular blade 7 can be used to cut the soil to facilitate soil sampling. An unloading component is also provided in the drill bit 6 for unloading the soil sample inside the sampling chamber 19.

[0025] To achieve the linkage of the rotation and lifting of the drill bit 6, the drilling and sampling device for forestry tree survey provided in this embodiment also includes a transmission component, which is located on one side of the outer casing 1, so that the guide sleeve 5 can be lifted and lowered to drive the guide rod 14 to rotate.

[0026] like Figure 2 and Figure 3 As shown, the unloading component provided in this embodiment includes an annular cavity 17 opened at the upper end of the drill bit 6. A movable sleeve 16 is slidably installed inside the annular cavity 17. Guide posts 20 are fixed at equal intervals at the lower end of the movable sleeve 16. The guide posts 20 extend into the material taking chamber 19 and are fitted with a pressure plate 18. A return spring 21 is installed on the outer side of the guide posts 20 between the movable sleeve 16 and the lower end of the annular cavity 17.

[0027] Specifically, during soil sampling, the return spring 21 relaxes so that the movable sleeve 16 is located at the upper end of the annular cavity 17, thereby placing the pressure plate 18 at the upper end of the sampling cavity 19 to facilitate soil sampling. When the soil sample is unloaded, the drill bit 6 rises so that the movable sleeve 16 abuts against the connecting ring 15. The connecting ring 15 squeezes the movable sleeve 16, thereby causing the guide post 20 to push the pressure plate 18 to move. The pressure plate 18 pushes out the soil sample inside the sampling cavity 19, thus facilitating soil unloading.

[0028] like Figure 1 and Figure 2 As shown, to facilitate the lifting and lowering of the guide sleeve 5, through slots 8 are provided on both sides of the outer shell 1. A connecting plate 10 is installed on the upper end of the guide sleeve 5. The connecting plate 10 is connected to the guide sleeve 5 by a bearing, and the connecting plate 10 is slidably connected to the through slot 8. A handle 12 is fixed on one side of the connecting plate 10 through the through slot 8. The handle 12 is used to drive the connecting plate 10 to lift and lower, thereby causing the connecting plate 10 to drive the guide sleeve 5 to lift and lower, and further realize the lifting and lowering of the drill bit 6.

[0029] like Figure 1 and Figure 2 As shown, the transmission component provided in this embodiment includes a transmission box 3 fixed to the upper end of the outer shell 1. A lead screw 9 is rotatably installed between the transmission box 3 and the base plate 2. A nut pair 11 adapted to the lead screw 9 is fixed to one end of the connecting plate 10. The connecting plate 10 is raised and lowered so that the nut pair 11 drives the lead screw 9 to rotate. Preferably, the lead screw 9 and the nut pair 11 are a helical transmission element with steel balls as rolling elements.

[0030] like Figure 4 and Figure 5 As shown, in this embodiment, the upper ends of the lead screw 9 and the guide rod 14 both extend into the transmission box 3 and are equipped with transmission wheels 22. A synchronous transmission belt 13 is provided between the two transmission wheels 22. The lead screw 9 drives the transmission wheel 22 to rotate, and the synchronous transmission belt 13 causes the other transmission wheel 22 to rotate, which in turn causes the guide rod 14 to rotate.

[0031] like Figure 1 As shown, the guide sleeve 5 provided in this embodiment is a stainless steel component to improve the corrosion resistance of the equipment. Scale lines are provided on the outside of the outer shell 1 to measure the depth of the drill bit 6 inserted into the soil.

[0032] The working principle and usage process of this utility model are as follows: When in use, pressing the handle 12 causes the connecting plate 10 to descend, which further drives the guide sleeve 5 to slide on the guide rod 14, thereby controlling the depth of the drill bit 6 inserted into the soil. During this process, the threaded connection between the nut pair 11 and the lead screw 9 causes the lead screw 9 to rotate. Through the transmission wheel 22 and the synchronous transmission belt 13, the lead screw 9 drives the guide rod 14 to rotate, which in turn causes the guide sleeve 5 to rotate, thereby causing the drill bit 6 to rotate. Under the action of the annular blade 7, the soil sample is cut to facilitate soil sampling.

[0033] After sampling is completed, the drill bit 6 rises so that the movable sleeve 16 abuts against the connecting ring 15. The connecting ring 15 squeezes the movable sleeve 16, thereby causing the guide column 20 to push the pressure plate 18 to move. The pressure plate 18 pushes out the soil sample inside the sampling chamber 19, thus facilitating the unloading of the soil.

[0034] It should be noted that, in this document, terms such as "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
