Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, and more specifically, to a deep-shovel-type trenching and pipe-laying machine for burying underground drip irrigation pipes in orchards. Background Art

[0002] Laying drip irrigation pipes below the tillage layer to irrigate the water and fertilizer needed by crops directly to the roots of crops is a new drip irrigation technology. This technology has the advantages of saving water, increasing production, saving labor, saving costs, and improving efficiency. It is suitable for the cultivation of field row crops such as tomatoes and potatoes.

[0003] In order to improve the efficiency of laying drip irrigation pipes and the degree of mechanical automation, trenching and pipe laying devices that integrate soil shoveling and pipe burying are often used. For example, the utility model patent with the authorization announcement number CN105464161B discloses a trenching and pipe laying device for burying underground drip irrigation pipes, which includes a frame and a trenching plow assembly, a soil covering and pressing assembly and a pipe laying assembly arranged on the frame. In the above patent, multiple operating assemblies are fixedly arranged at intervals along the lateral direction of the frame, and multiple rows of operations can be performed simultaneously. Although the above patent technology improves the laying efficiency and the degree of mechanical automation, the row spacings of different crops are different. The multiple parallel operating components of the above-mentioned patent are fixed, and the spacing of the multiple operating components cannot be adjusted in time according to the row spacing of the crops, which limits the scope of application of the trenching and pipe laying device; in addition, the above-mentioned patent requires that the drip irrigation pipe to be laid be wound onto the rotating shaft of the pipe laying component before the operation, which has the defects of inconvenient operation, time-consuming and labor-intensive; furthermore, compared with field row-sown crops such as tomatoes and potatoes, the roots of fruit trees in orchards are distributed deeper, and the position for laying the underground drip irrigation pipe is required to be deeper, and the operation is more difficult. The trenching and pipe laying device of the prior art cannot meet the burial operation of the underground drip irrigation pipe in the orchard. Utility Model Content

[0046] Two ditching mechanisms, one ditching mechanism is arranged at the front end of each support frame 2, and a drip irrigation pipe guiding mechanism is arranged at the rear end of each ditching mechanism;

[0047] Two drip irrigation pipe placement mechanisms, one drip irrigation pipe placement mechanism is arranged on each support frame 2, each drip irrigation pipe placement mechanism comprises a circular frame 41 which is horizontally rotatably arranged on the support frame 2 and a support sleeve 42 which is vertically arranged in the middle of the circular frame 41, the axis of the support sleeve 42 passes through the center of the circular frame 41, and the rolled drip irrigation pipe to be buried is sleeved on the support sleeve 42;

[0048] Two depth limiting and suppressing wheels 5 are provided at the rear end of each support frame 2, and the travel direction of the depth limiting and suppressing wheel 5 is consistent with the travel direction of the tractor; the free end of the drip irrigation pipe passes through the bottom of the depth limiting and suppressing wheel 5 longitudinally through the guide mechanism and extends to one end of the orchard.

[0049] In the above technical scheme, the utility model provides a deep loosening shovel type trenching pipe laying machine for burying underground drip irrigation pipes in an orchard, which includes a frame 1, a front end of which is arranged in the longitudinal direction (the travel direction of the tractor is the longitudinal direction) and is provided with a suspension mechanism connected to a tractor (such as a tractor or other travel power source), and both sides of the frame 1 arranged in the transverse direction (perpendicular to the travel direction of the tractor) are respectively connected in a transverse sliding manner with a support frame 2, a trenching mechanism for opening a groove is arranged at the front end of each support frame 2, and a depth-limiting pressing wheel 5 for laying the drip irrigation pipe in the groove is arranged at the rear end, and a placement mechanism for placing the drip irrigation pipe is also provided on the support frame 2, and the drip irrigation pipe to be buried is placed on the support frame 2. , the drip irrigation pipe roll in the shape of a circular cylinder can be directly sleeved on the support sleeve 42, the head of the drip irrigation pipe of the drip irrigation pipe roll passes through the bottom of the depth-limiting pressing wheel 5 in the longitudinal direction through the guide mechanism, and then is fixed to one end of the orchard (the starting end of the tractor), and during the laying process, as the tractor moves forward, a pulling traction force is generated on a section of the drip irrigation pipe released from the drip irrigation pipe roll, thereby driving the circular frame 41, the support sleeve 42, and the drip irrigation pipe roll to rotate in a circle, and the drip irrigation pipe is rolled and released, and the drip irrigation pipe gradually rotated and released from the drip irrigation pipe roll is laid flat in the longitudinal direction in the groove opened by the trenching mechanism, and is buried in the groove under the pressing and covering action of the depth-limiting pressing wheel 5;

[0050] like Figure 1 As shown, the frame 1 can be composed of a pair of mutually parallel cross bars and a plurality of longitudinal bars connecting the pair of cross bars, the support frame 2 is a U-shaped structure, the two vertical parts of the support frame 2 are inserted into the same end of the pair of cross bars, and the vertical parts of the support frame 2 are connected to the inner walls of the corresponding cross bars in a lateral sliding manner, so that the two support frames 2 can be pushed and pulled relative to the frame 1 in the lateral direction, and then the positions of the two support frames 2 in the lateral direction can be adjusted, so that the lateral spacing of the two ditching mechanisms, the two drip irrigation pipe placement mechanisms, and the two pipe laying mechanisms can be adjusted according to the row spacing of the fruit trees, thereby increasing the application scope of the pipe laying machine of the utility model;

[0051] The drip irrigation pipe roll to be buried (the drip irrigation pipe roll with a circular cylindrical packaging layer purchased on the market) is sleeved on the support sleeve 42, which is convenient for the placement operation of the drip irrigation pipe, saves time and effort, and eliminates the need to manually wrap the drip irrigation pipe around the rotating shaft before the drip irrigation pipe is buried in the prior art;

[0052] When the utility model is in use, the frame 1 is connected to the tractor through the suspension mechanism, the drip irrigation pipe reel is arranged on the support sleeve 42, the free end of the drip irrigation pipe moves longitudinally through the bottom of the depth limiting pressing wheel 5 via the guide mechanism, and continues to extend to one end of the orchard (the tractor moves from one end of the orchard to the other end) for fixed connection, the tractor is started to drive the frame 1 to move longitudinally in the orchard, and the front end trenching mechanism is driven to open a trench in the orchard longitudinally. Because the free end of the drip irrigation pipe is fixed, the tractor pulls the tractor to move the frame 1 longitudinally in the orchard. Under the action of the traction machine, a section of the drip irrigation pipe released from the drip irrigation pipe roll is in a tensioned state. As the traction machine moves, the annular frame 41, the support sleeve 42 and the axis of the drip irrigation pipe winding support sleeve 42 are driven to rotate, and the drip irrigation pipe is released. The released drip irrigation pipe is laid in the groove under the pressure of the depth limiting pressing wheel 5, and the groove is covered with soil and rolled under the action of the depth limiting pressing wheel 5, so that the drip irrigation pipe is buried in the soil layer of the orchard. The traction machine moves to the other end of the orchard, and the drip irrigation pipe is cut off, that is, the burial of a row of drip irrigation pipes is completed.

[0053] The utility model provides a support frame 2 on both sides of the frame 1 for sliding along the horizontal direction, and each support frame 2 is provided with a set of ditching mechanisms, drip irrigation pipe placing mechanisms and depth limiting pressing wheels 5 corresponding to each other along the longitudinal direction, so as to realize the burying operation of single-row or double-row drip irrigation pipes. When the burying operation of double-row drip irrigation pipes is carried out, the support frame 2 can be moved laterally relative to the frame 1, and the spacing between the two support frames 2 can be adjusted according to the row spacing, and then the spacing between the two ditching mechanisms / two drip irrigation pipe placing mechanisms / two depth limiting pressing wheels 5 can be adjusted, so that the pipe laying machine of the utility model can be suitable for the burying operation of drip irrigation pipes in orchards with different row spacings, which greatly improves the application scope of the pipe laying machine; further, a horizontally rotating ring frame 41 is provided to facilitate the placement operation of the drip irrigation pipe, and during the laying process, the drip irrigation pipe between the drip irrigation pipe roll and the depth limiting pressing wheel 5 is in a tensioned state, so as to avoid the drip irrigation pipe in this area being too long, resulting in the drip irrigation pipe knotting and affecting the normal burying operation of the drip irrigation pipe.

[0054] The ditching and pipe laying machine for burying drip irrigation pipes provided by the utility model is not limited to being applicable to orchards, but is also applicable to burying operations of drip irrigation pipes in other crop fields.

[0055] In another technical solution, in the deep loosening shovel type trenching and pipe laying machine for burying underground drip irrigation pipes in the orchard, each depth limiting and pressing wheel 5 is connected to the rear end of the support frame 2 through a first telescopic sleeve 51, and each first telescopic sleeve 51 includes two first sleeves slidably sleeved in the vertical direction, one of the first sleeves is detachably connected to the rear end of the support frame 2, and the depth limiting and pressing wheel 5 is rotatably arranged at the bottom of the other first sleeve.

The two first sleeves are hollow and have perforations at intervals on the side in the vertical direction. A circular tube body or a rectangular tube body can be selected. After the two first sleeves are adjusted in height and moved into place in the vertical direction, they correspond along the horizontal perforations, and a latch or other horizontal rod is inserted into the corresponding perforations of the two first sleeves in the horizontal direction to fix the two first sleeves. The structure and temporary fixing method of the two first sleeves can also be achieved by other existing technical means, ensuring that the first telescopic sleeve 51 can be telescopic in the vertical direction. One of the first sleeves can be fixed to a vertical portion (a vertical portion at the rear end) of the support frame 2 by a U-shaped bolt.

[0056] In another technical solution, the deep loosening shovel type trenching pipe laying machine for burying underground drip irrigation pipes in an orchard, each trenching mechanism includes:

[0057] A mounting frame 31, which is disposed at the front end of the support frame 2;

[0058] A trenching shovel 32 is disposed at the front end of the mounting frame 31; a cutting blade 36 extending obliquely downward is disposed at the end of the trenching shovel 32, and the thickness of the cutting blade 36 gradually decreases from top to bottom;

[0059] A guide tube 33, which is disposed at the rear end of the mounting frame 31;

[0060] A guide wheel 34, which is disposed at the rear end of the mounting frame 31 and is located above the guide tube 33;

[0061] The guide groove 35 is vertically arranged at the rear end of the mounting frame 31 and is located between the guide pipe 33 and the guide wheel 34; the drip irrigation pipe passes through the guide wheel 34, passes through the guide groove 35 and the guide pipe 33 in sequence, and then passes under the depth limiting pressing wheel 5 to extend to one end of the orchard for fixation.

[0062] In the above technical scheme, the utility model discloses the specific structure of the trenching mechanism, each trenching mechanism includes a mounting frame 31 arranged at the front end of the support frame 2, a trenching shovel 32 for trenching is arranged at the front end of the mounting frame 31, the trenching width of the trenching shovel 32 is slightly larger than the diameter of the drip irrigation pipe, so as to ensure that the drip irrigation pipe can be buried in the trench, a guide pipe 33 for guiding the drip irrigation pipe is arranged at the rear end of the mounting frame 31, a guide wheel 34 is arranged at the upper end of the guide pipe 33, and the guide wheel 34 is connected to the guide pipe 33 through a guide groove 35, and the guide wheel 34, the guide groove 35 and the guide pipe 33 form a guiding mechanism for the drip irrigation pipe, which is used to guide the drip irrigation pipe to the bottom of the depth limiting pressing wheel 5, and the guiding mechanism is arranged to avoid the drip irrigation pipe from tying during the laying process, so as to ensure the smoothness of the drip irrigation pipe laying, and thus ensure the normal progress of the burying operation; Figure 1 As shown, the end of the drip irrigation pipe moves to the front end through the guide wheel 34, the guide groove 35, and the guide pipe 33, and then moves to the rear end and passes under the depth limiting pressing wheel 5, extends out and is then fixed to one end of the orchard.

[0063] In another technical solution, in the deep tillage shovel type trenching pipe laying machine for burying underground drip irrigation pipes in the orchard, each circular frame 41 is horizontally rotatably arranged on the support frame 2 through a connecting mechanism, and each connecting mechanism includes a first support rod 61 vertically arranged on the support frame 2 and a second support rod 62 that slides horizontally along the longitudinal direction and is arranged on the top of the first support rod 61. The bottom of the circular frame 41 is horizontally rotatably arranged on the second support rod 62. The second support rod 62 is arranged horizontally along the longitudinal direction, and the second support rod 62 is slidably connected to the first support rod 61 along the longitudinal direction, so that the second support rod 62 can be moved longitudinally relative to the first support rod 61, thereby adjusting the distance between the support sleeve 42 and the guide wheel 34. As the burying operation proceeds, the diameter of the drip irrigation tube sleeved on the support sleeve 42 will become smaller and smaller, and the distance between the drip irrigation tube and the guide wheel 34 will become larger. At this time, the distance between the drip irrigation tube and the guide wheel 34 can be adjusted by moving the second support rod 62 longitudinally to ensure that a section of the drip irrigation tube released from the drip irrigation tube roll is always in a tensioned state, thereby ensuring the normal and smooth progress of the burying operation.

[0064] In another technical solution, the deep loosening shovel type trenching pipe laying machine for burying the underground drip irrigation pipe in the orchard is provided with a cutting blade 36 extending obliquely downward at the end of the trenching shovel 32, and the thickness of the cutting blade 36 gradually decreases from top to bottom. By arranging the cutting blade 36 at the end of the trenching shovel 32, the soil can be cut first in the trenching process, and then the trench is formed to form a groove, which greatly reduces the resistance of the soil to the trenching mechanism, thereby reducing the horsepower requirement of the traction machine power source, and a small power source can be used, which reduces the volume of the power source, and is very friendly to the burial of the drip irrigation pipe in the orchard where the site is not large. The trenching width of the cutting blade 36 and the trenching shovel 32 is slightly larger than the width of the drip irrigation pipe, ensuring that the drip irrigation pipe can be buried in the groove.

By setting the second telescopic sleeve, the vertical position of the mounting frame 31 can be adjusted, and then the trenching depth of the trenching shovel 32 can be adjusted according to the designed burying depth of the drip irrigation pipe. The structure and temporary fixing method of the two second sleeves can refer to the two first sleeves, which will not be repeated here.

[0066] In another technical solution, in the deep-shovel trenching pipe laying machine for burying underground drip irrigation pipes in an orchard, each drip irrigation pipe placing mechanism further includes a plurality of vertical poles 43, which are vertically arranged on the edge of the circular frame 41 at intervals along the circumferential direction. The plurality of vertical poles 43 can be provided to protect the periphery of the cylindrical drip irrigation pipe sleeved on the support sleeve 42, so as to prevent the peripheral part of the cylindrical drip irrigation pipe from being scattered in the circumferential direction due to the rotation of the circular frame 41 during the laying process, thereby causing the cylindrical drip irrigation pipe to collapse and affect the normal burying operation.
