Description

Technical Field

[0001] The utility model relates to the technical field of crop planting, in particular to a portable farmland ditching device. Background Art

[0002] Trenching and ridge making is a common agricultural operation with the following benefits: 1. It can effectively drain water to avoid excessive water in the fields, which will affect the growth of crops; 2. For heavy clay soils, trenching and applying a large amount of organic fertilizer can improve soil properties, increase soil permeability, and is beneficial to the growth of crops; 3. It can prune the roots of some heavy clay soils, promote the growth of more new roots, and enhance the absorption capacity of crops; 4. It can increase the organic matter in the soil, retain water and fertilizer; 5. It can make the fertilizer and soil in closer contact, reduce the volatilization and loss of fertilizer, and improve the utilization rate of fertilizer; 6. It is convenient for irrigation to ensure that crops get sufficient water during the growth process; 7. It prevents soil compaction and ensures the looseness and permeability of the soil.

[0003] Currently, commonly used trenching equipment includes large tractor trenching equipment and small manual trenching machines. Large tractor trenching equipment is used to trench large areas of land, and small manual trenching machines are used to trench small areas of land and areas that are inconvenient for tractors to enter. When using small manual trenching machines for trenching operations, it is difficult for operators to control the spacing of trenches, resulting in the problem of uneven spacing of trenches, and the trenches are prone to skewness, which affects the normal growth of crops.

[0004] In order to solve the above technical problems, the technical solution of the Chinese utility model patent announcement with patent application number CN202320933648.9 is a farmland furrowing device, including a handle and a connecting rod, one end of the handle is fixedly connected to the connecting rod, the other end of the connecting rod is fixedly connected to the connecting frame, the inner side of the connecting frame is rotatably connected to a wheel, one end of the connecting frame is fixedly connected to a connecting plate, and the other end of the connecting plate is fixedly connected to a plowshare. The furrowing spacing can be determined by the mutual cooperation of the limit rod and the benchmark rod, so as to ensure that the furrowing spacing is the same, and it can also be ensured that there will be no skew when furrowing. At the same time, by adjusting the position of the limit rod and the benchmark rod, different furrowing spacings and furrowing depths can be met. During the furrowing process, when the crop straw and rhizomes in the soil are accumulated on one side of the plowshare and the connecting rod, the staff shakes the connecting rod with the pull rope, and the crop straw and rhizomes are shaken off from one side of the plowshare and the connecting rod by the shaking of the connecting rod, so that it is convenient for the staff to pull the device to furrow.

[0005] However, the above-mentioned prior art has the following technical problems: when the above-mentioned farmland furrowing device is used to furrow, in order to ensure that the furrowing spacing is the same, it is necessary to first open a first furrow that meets the requirements, and then adjust the positions of the limit rod and the connecting rod according to the furrowing spacing, and determine the position of the limit rod by the scale line on the limit rod, so that the benchmark is above the edge of the first furrow opened, and then the limit rod is fixed and the benchmark is moved downward to make the benchmark close to the edge of the first furrow opened, and then the furrowing can be carried out by the plowshare. The above-mentioned farmland furrowing device can only open one furrow at a time, and the furrowing efficiency is low. Utility Model Content

[0006] In view of this, it is necessary to provide a portable farmland furrowing device that can dig multiple furrows at the same time.

[0007] A portable farmland trenching device comprises a crossbeam, an operating rod and at least two shovels with the same structure. The crossbeam is in the shape of a straight column, and wheels are rotatably mounted on both ends of the crossbeam. The operating rod is mounted on the side of the crossbeam. At least two mutually parallel fixing members are evenly arranged on the side of the crossbeam along the axial direction of the crossbeam. Each shovel is fixedly mounted in the corresponding fixing member according to the spacing requirements, and is used to dig multiple trenches that meet the spacing requirements at the same time.

[0008] Preferably, the crossbeam is in the shape of a cylinder, and at least three first adjustment holes are evenly opened along the circumferential direction of the crossbeam at a position for installing the operating rod, and threads are opened in the first adjustment holes for fixedly installing the operating rod.

[0009] Preferably, each fixing member is a cylindrical structure with openings at both ends, one side of each fixing member is fixed to the crossbeam, and the other side of each fixing member is provided with a fixing hole for fixing the shovel, and the direction of the openings at both ends of the fixing member is the same as the radial direction of the crossbeam.

[0011] Preferably, the operating rod includes a pull rod and two connecting rods with the same structure. The top end of each connecting rod can be detachably mounted on the pull rod, and the bottom end of each connecting rod is provided with a fan-shaped connecting piece. Two connecting holes are evenly opened on the connecting piece along the circumferential direction of the connecting piece for fixedly connecting the bottom of the connecting rod and the cross beam.

[0012] The portable farmland trenching device is provided with a crossbeam, an operating rod and at least two shovels of the same structure.

DETAILED DESCRIPTION

[0020] The technical scheme and technical effects of the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings of the present invention.

[0021] Please refer to Figure 1A portable farmland trenching device 10 includes a crossbeam 20, an operating rod 30 and at least two shovels 40 with the same structure. The crossbeam 20 is in the shape of a straight cylinder. In the utility model, a cylinder is used for easy casting. Both ends of the crossbeam 20 are rotatably provided with wheels 21. The operating rod 30 is installed on the side of the crossbeam 20. At least two mutually parallel fixing members 22 are evenly arranged on the side of the crossbeam 20 along the axial direction of the crossbeam 20. Each shovel 40 is fixedly installed in the corresponding fixing member 22 according to the spacing requirements. In this way, by fixing the shovel 40 to the fixing members 22 that are parallel to each other and have the same spacing, multiple trenches with the same spacing can be dug on the farmland at the same time. The spacing between any two adjacent shovels 40 can also be adjusted by installing the shovel 40 in different fixing members 22, thereby changing the spacing between any two adjacent trenches.

[0022] Please refer to Figure 2 Furthermore, the shape of the beam 20 is a cylinder, and at least three first adjustment holes 23 are evenly opened along the circumferential direction of the beam at the position for installing the operating rod 30. The first adjustment holes 23 are threaded so that the operating rod 30 can be fixedly connected to the beam 20 by bolts.

[0023] Please refer to Figure 3 Furthermore, each fixing member 22 is a cylindrical structure with openings at both ends. One side of each fixing member 22 is fixed on the beam 20, and the other side of each fixing member 22 is provided with a fixing hole 221 for fixing and installing the shovel 40. The direction of the openings at both ends of the fixing member 22 is the same as the radial direction of the beam 20, so that the shovel 40 can face the radial direction of the beam 20 when installed in the fixing member 22, so that the direction of the shovel 40 is consistent when trenching, ensuring that all trenches are parallel.

[0024] Please refer to Figure 4 In this embodiment, each shovel 40 includes a shovel head 41 and a shovel handle 42. The shovel head 41 is fixedly mounted on one end of the shovel handle 42, and the other end of the shovel handle 42 extends into the opening of the fixing member 22. At least two second adjustment holes 43 of the same size are evenly opened on the shovel handle 42. The second adjustment holes 43 are threaded so that the second adjustment holes 43 can be fixedly connected to the fixing holes 221 by screws, and the length of the shovel head 41 extending from the beam 20 can be adjusted by selecting different second adjustment holes 43 to be fixedly connected to the fixing holes 221 to adjust the depth of the trenching, thereby meeting the needs of different crops.

[0025] In this embodiment, a plurality of shovel heads 41 of different sizes are provided so that the width of the trench can be changed by replacing the shovel heads 41 to meet the needs of different crops.

[0026] Please refer to Figure 5 to Figure 6Furthermore, the operating rod 30 includes a pull rod 31 and two connecting rods 32 of the same structure. The top end of each connecting rod 32 is detachably mounted on the pull rod 31 to split the operating rod 30 into the pull rod 31 and the connecting rod 32, so as to facilitate carrying. The bottom end of each connecting rod 32 is provided with a fan-shaped connecting piece 321, and two connecting holes 322 are evenly opened on the connecting piece 321 along the circumferential direction of the connecting piece 321, which are used to fix the bottom of the connecting rod 32 and the crossbeam 20, and the angle between the connecting rod 32 and the shovel 40 is adjusted by fixing the connecting hole 322 and different first adjustment holes 23. When trenching, according to the different soil qualities, the angle between the connecting rod 32 and the shovel 40 is appropriately increased on harder land, so that the operator can apply force to insert the shovel head 41 into the soil.

[0027] The following steps are included when using the portable farmland trenching device 10 to trench:

[0028] 1. Prepare and level the soil of the field where crops are to be planted in advance;

[0029] 2. Determine the width, spacing and depth of the trenches according to the types of crops to be planted;

[0030] 3. Select a corresponding shovel head 41 according to the width of the groove, and install the shovel head 41 on the shovel handle 42;

[0031] 4. Install the shovel handle 42 into the corresponding fixing member 22 according to the spacing of the grooves;

[0032] 5. Select the corresponding second adjustment hole 43 according to the depth of the groove and fix the second adjustment hole to the fixing hole 221 by bolts;

[0033] 6. According to the hardness of the soil, select the corresponding first adjustment hole 43 to connect with the connecting hole 322 to adjust the angle between the operating rod 30 and the shovel 40, so that the operator can apply pressure to the shovel 40 through the operating rod 30 when digging a trench;

[0034] 7. Aim the shovel head 41 at the position where the trench is to be dug and pull the operating rod 30 to move the portable farm field trenching device 10 in the field to perform the trenching operation.

[0035] Compared with the technical solution of the Chinese utility model patent announcement with patent application number CN202320933648.9, the technical solution provided by the utility model is that when performing trenching operations, the utility model only needs to first determine the width, spacing and depth of the trench according to the type of crops planted, and then select the corresponding shovel head 41 according to the width of the trench and install it on the shovel handle 42; install the shovel handle 42 to the corresponding fixing member 22 according to the spacing of the trench; fix the corresponding second adjustment hole 43 to the fixing hole 221 according to the depth of the trench; then align the shovel head 41 with the position where the trench is to be opened in the field, and then pull the portable farmland trenching device 10 to simultaneously open multiple trenches that meet the requirements in the field.

[0036] The Chinese utility model patent with patent application number CN202320933648.9 requires workers to use handles and connecting rods to lead the plowshare to first open the first trench on the ground, and then open the remaining trenches based on the first trench, while ensuring that the first trench meets the requirements. Then the workers adjust the position of the limit rod and the benchmark according to the spacing between the trenches, and determine the position of the limit rod through the scale line on the limit rod, so that the benchmark is above the edge of the first trench opened, and limit the limit rod through the second locking screw, and move the benchmark downward so that it is close to the edge of the first trench opened, and then the plowshare can be used to open trenches. At the same time, by observing the positional relationship between the benchmark and the edge of the first trench opened, it is ensured that the spacing of the opened trenches will not change, and it can also be ensured that the opened trenches will not be skewed.

[0037] In contrast, the utility model only needs to adjust the shovel head 41, the shovel handle 42 and the second adjustment hole 43 according to the type of crops before trenching, so that the width, spacing and depth of the trenches meet the needs of the crops to be planted. After that, the portable farmland trenching device 10 can be pulled to dig trenches in the field. The operation is simple, and as long as the type of crops to be planted remains unchanged, there is no need to adjust the shovel head 41, the shovel handle 42 and the second adjustment hole 43.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
