Description

Technical Field

[0001] The invention relates to the technical field of agricultural field ditch ridging equipment, and in particular to a field ditch digging device in a strawberry planting greenhouse. Background Art

[0002] Before planting strawberries, the soil needs to be properly treated to ensure that the soil has good drainage and aeration, which is essential for the healthy growth of strawberries. Generally speaking, the soil is first plowed using a rotary tiller, plow or other farm tools, usually at a depth of about 20-30 cm, to break up clods and loosen the soil. During the plowing process, weeds and grass roots in the soil are removed, and then ridges are formed using a ridger or manual methods to form ridges and ditches between ridges.

[0003] During use, the ridging machine of the prior art can form ridges well and also water the soil before forming ridges, but it lacks a mechanism for patting and compacting the ridges, so that the ridges are still easy to collapse after being formed for a period of time. For this reason, the present application provides a field ditch excavation device in a strawberry planting greenhouse. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the ridging machine in the prior art lacks a mechanism for beating and compacting the ridges during use, so that the ridges are still easily collapsed after being formed for a period of time. The present invention provides a field ditch excavation device in a strawberry planting greenhouse.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] A device for digging trenches in a strawberry planting greenhouse, comprising a walking tractor and a connecting member connected to the walking tractor;

[0007] The connecting member is connected with a metal piece, and both ends of the metal piece are connected with a ridge wall plate, and the metal piece is slidably connected to the connecting member and can move vertically upward and downward;

[0008] The ridge forming wall plate includes a soil guide plate which is arranged in an inclined direction with respect to the moving direction of the ridge forming wall plate and is fixedly connected to the metal member, and a ridge forming wall plate which is integrally constructed with the soil guide plate and is used for ridge forming, and also includes an edge plate which is arranged horizontally and integrally constructed on the edges of the soil guide plate and the ridge forming wall plate;

[0009] A driving mechanism is provided at the bottom of the connecting member, and the driving mechanism is used to drive the metal parts to move up and down intermittently, so that the soil guide plate, the ridge wall plate and the edge plate are slapped on the side wall of the ridge after the ridge is formed.

[0010] Furthermore, the connecting member includes a mounting plate with a "ㄈ" structure, and two connecting plates with mounting holes are fixed to the back side of the mounting plate.

[0011] Furthermore, the mounting plate is constructed with a through-type square hole in the thickness direction, a support plate is vertically fixed to the front side of the metal part, a guide rod that slides through the through-type square hole is vertically fixed to the top side of the support plate, a transverse lifting rod is fixed to the part of the guide rod located within the "ㄈ" shape of the mounting plate, and the top and bottom surfaces of the lifting rod are both provided with springs that are fixedly connected to the "ㄈ"-shaped inner wall of the mounting plate.

[0012] Furthermore, the driving mechanism includes a pair of leg plates that slide through the support plate and are fixed corresponding to the two connecting plates, an axle is rotatably installed between the two leg plates, a wheel is fixed on the axle, a cam is also fixed on the axle, a contact plate is vertically fixed to the bottom of the support plate, a contact through window is constructed on the contact plate for the cam to be inserted, and the cam touches the upper top wall or the lower bottom wall of the contact through window when it rotates.

[0013] Furthermore, an insert sleeve is fixed at one end of the edge plate away from the metal part, and a pressure plate is detachably installed in the insert sleeve. The pressure plate includes an insert rod inserted in the insert sleeve, and a plate surface integrally constructed with the insert rod. The plate surface is constructed in a serrated shape on one side and the insert rod is fastened in the insert sleeve by bolts.

[0014] Furthermore, the horizontal cross-section of the metal part is "C"-shaped and elastic, and the two end walls can be deformed to open or close under force.

[0015] Furthermore, a pair of driving blocks are symmetrically arranged between the two ridge wall plates, and the two driving blocks are fixedly connected to the ridge wall plates through a bracket rod. The opposite surfaces of the two driving blocks are constructed with driving grooves, and the two driving grooves are combined to form a diamond shape. Diamond blocks are adapted to be arranged in the two driving grooves and the diamond blocks are fixed to the mounting plate through brackets.

[0016] Furthermore, a pair of wing frames are symmetrically fixed on the top of the installation template, and the two wing frames are movably mounted with ridge forming wall panels.

[0022] The present invention is affected by the diamond blocks and the contact through-windows, and the soil guide plates, ridge wall plates and edge plates also have the effect of simultaneously compacting the side walls of the ridges and the top. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] The present embodiment provides a field ditch digging device in a strawberry planting greenhouse, which is mainly used to solve the problem that the ridging machine in the prior art lacks a mechanism for beating and compacting the ridges during use, so that the ridges are still easy to collapse after being formed for a period of time, and provides the following technical solutions. Figure 1-Figure 9 Make a detailed description: Example

[0035] A device for digging trenches in a strawberry planting greenhouse comprises a walking tractor 1, which is a small walking tractor used for plowing in the field, wherein a connecting member 2 is connected to the traction plowshare of the walking tractor 1;

[0036] A metal piece 3 with an arc-shaped cross section is connected to the connecting member 2, and both arc-shaped ends of the metal piece 3 are connected with a ridge wall plate 4. The connection relationship between the metal piece 3 and the connecting member 2 is a sliding connection, and the metal piece 3 can move vertically upward and downward;

[0037] The ridge forming wall plate 4 includes a soil guide plate 401 which is arranged to be inclined with respect to its own movement direction and fixedly connected to the metal member 3, and a ridge forming wall plate 402 which is integrally constructed with the soil guide plate 401 and is used for ridge forming. The metal member 3 and the soil guide plate 401 can be formed as follows: Figure 6 The screw-fixed connection shown in the figure can also be connected by welding. At the same time, in order to make the top of the ridge pile flat, it also includes an edge plate 403 which is horizontally arranged and integrally constructed on the upper edge of the soil guide plate 401 and the ridge wall plate 402;

[0038] A driving mechanism 5 is provided at the bottom of the connecting member 2, and the driving mechanism 5 is used to drive the metal member 3 to move up and down intermittently, so that the soil guide plate 401, the ridge wall plate 402, and the edge plate 403 are formed into a ridge and then slapped against the side wall of the ridge.

[0039] During operation: after the walking tractor 1 is started, it moves in the greenhouse. At this time, the field soil used for ridge formation has been crushed in advance by a rotary tiller. The soil is loose and has been soaked with water. When the walking tractor 1 moves, it can drive the connecting member 2 to pull the metal member 3 to move. The soil guide plates 401 obliquely connected to the two ends of the metal member 3 push the soil to both sides and are shaped into the side wall style of the ridge by the inclined structural surface of the ridge wall plate 402. At the same time, the edge plate 403 smoothes the top of the ridge, realizing the initial structure of the ridge. In order to prevent the ridge from collapsing in the subsequent process, under the action of the driving mechanism 5, the metal member 3 moves up and down intermittently, and the metal member 3 is slidably connected to the connecting member 2 up and down. When the metal member 3 moves upward, it can drive the soil guide plate 401, the ridge wall plate 402, and the edge plate 403 fixedly connected thereto to move upward first, and then fall downward and hit the initially constructed ridge, so that the side wall and the top of the ridge can be knocked and compacted, reducing the problem of the ridge being easy to collapse during subsequent use.

[0040] like Figure 3 As shown, in this embodiment, the connecting member 2 includes a mounting plate 201 with a "ㄈ" structure, and two connecting plates 203 with mounting holes 202 are fixed on the back of the mounting plate 201. Figure 3 The mounting holes 202 on the two connecting plates 203 are used for bolts to pass through and then be installed at the connection of the walking tractor 1 (i.e., replacing the position of the plowshare, which is the prior art).

[0041] like Figures 6 to 8 As shown, in this embodiment, the thickness of the mounting plate 201 is structured with a through-type square hole 204, the front of the metal part 3 is vertically fixed with a support plate 301, and the top surface of the support plate 301 is vertically fixed with a guide rod 302 that slides through the through-type square hole 204. The guide rod 302 is fixed to the support plate 301 and slides through the through-type square hole 204, so that the metal part 3 and the mounting plate 201 are connected in an up-and-down sliding relationship. At the same time, in order to achieve smooth relative displacement between the two and within a certain range, the guide rod The part 302 located in the "ㄈ" shape of the mounting plate 201 is fixed with a horizontal lifting rod 303, and the top and bottom surfaces of the lifting rod 303 are provided with springs 304 fixedly connected to the "ㄈ" shaped inner wall of the mounting plate 201, one end of the spring 304 is fixed to the top surface of the lifting rod 303, and the other end is fixed to the mounting plate 201, so that when the guide rod 302 moves along the through-type square hole 204, the lifting rod 303 fixed vertically to the guide rod 302 is forced to be in a balanced state under the action of the spring 304.

[0042] like Figures 6 to 9 As shown, in this embodiment, in order to enable the metal member 3 to obtain the function of intermittent up and down movement, the driving mechanism 5 includes a pair of leg plates 501 that slide through the support plate 301 and are fixed to the two connecting plates 203. A shaft 502 is rotatably installed between the two leg plates 501, and a wheel 503 is fixed on the shaft 502. A cam 504 is also fixed on the shaft 502. The cam 504 here is shaped as shown in FIG. Fig. 9 As shown in FIG. 3 , a contact plate 505 is vertically fixed to the bottom of the support plate 301. The contact plate 505 is configured with a contact through window 506 for the cam 504 to be inserted. When the cam 504 rotates, it touches the upper top wall or the lower bottom wall of the contact through window 506. Please refer to FIG. Fig. 9 When the walking tractor 1 moves, the wheel 503 on the shaft 502 can be driven to rotate. Therefore, the wheel diameter of the wheel 503 here is small. Therefore, even if the walking tractor 1 moves slowly, the rotation of the wheel 503 here is still faster than the rotation of the wheel of the walking tractor 1 itself. When the wheel 503 rotates, the shaft 502 fixed thereto can be driven to rotate. The rotation of the shaft 502 can drive the cam 504 to rotate. When it rotates to touch the lower bottom wall of the contact through window 506, the support plate 301 fixed to the contact plate 505 can be pulled to drive the guide rod 302 and the metal part 3 downward. At this time, the soil guide plate 401, the ridge wall plate 402, and the edge plate 403 fixed to the metal part 3 move toward the side wall of the initially constructed ridge, so that the side wall of the ridge and The top is struck and compacted, and when it rotates to touch the upper top wall of the contact through window 506, the soil guide plate 401, ridge wall plate 402, and edge plate 403 fixed to the metal part 3 move vertically upward, providing a prerequisite for the next striking of the initially formed ridge, and combined with the high rotation speed of the wheel 503 here, it can produce the effect of multiple striking of the side walls of the initially formed ridge. At the same time, because the speed of the hand tractor 1 is relatively low, and the length formed by the soil guide plate 401, ridge wall plate 402, and edge plate 403 is long enough, a section of the initially formed ridge can be struck and compacted multiple times, and because springs 304 are arranged above and below the lifting rod 303, it can be quickly reset when the cam 504 is away from the upper top wall or lower bottom wall of the contact through window 506.

[0043] like Figure 5As shown, in the present embodiment, in order to expand the ability of the edge plate 403 to flatten the top of the ridge, an insert tube 6 is fixed to the end of the edge plate 403 away from the metal member 3, and a flat plate 7 is detachably installed in the insert tube 6. The flat plate 7 includes an insert rod 701 inserted in the insert tube 6, and a plate surface 702 integrally constructed with the insert rod 701. When the plate surface 702 and the insert rod 701 follow the insert tube 6 and the edge plate 403 to hit the top surface of the ridge downward, more flattening length for the top surface of the ridge can be provided, and the plate surface 702 is constructed in a serrated shape on one side. The serrated shape can produce a serrated texture on the top surface of the ridge, and the texture can allow moisture to stay on the top of the ridge during watering in the later stage. At the same time, in order to adapt to ridges of different widths, the insert rod 701 here is fastened in the insert tube 6 by bolts, and flat plates 7 of different lengths can be replaced in turn according to ridges of different widths. Example

[0044] like Figure 5 and Figure 7As shown, the horizontal cross-section of the metal member 3 is "C"-shaped and elastic, and the two end walls can be deformed by force to open or close, and the two "C"-shaped ends of the metal member 3 are connected to the ridging wall panels 4. When the two ridging wall panels 4 are subjected to force, they can be deformed at the metal member 3 to make the two ridging wall panels 4 open or close. At the same time, a pair of driving blocks 8 are symmetrically arranged between the two ridging wall panels 402. The two driving blocks 8 are fixedly connected to the corresponding ridging wall panels 402 through the bracket rod 9. The opposite surfaces of the two driving blocks 8 are constructed with driving grooves 10. The two driving grooves 10 are combined into a diamond shape and are located at the two A diamond block 11 is adapted to be arranged in each driving groove 10 and the diamond block 11 is fixed on the mounting plate 201 through a bracket 12. When the metal part 3 drives the ridge wall plate 402 to move up and down, the bracket 12 fixed to the mounting plate 201 and the diamond block 11 will not move up and down. At this time, the inclined surface of the diamond block 11 itself acts on the inclined surface of the driving groove 10, thereby driving the two driving blocks 8 to move away from each other. The two driving blocks 8 moving away from each other can push the two ridge wall plates 402 away from each other through the bracket rod 9, thereby playing a role in compacting the initially formed ridge. It should be emphasized that: when the convex When the wheel 504 rotates to touch the upper top wall of the through window 506: at this time, the soil guide plate 401, the ridge wall plate 402, and the edge plate 403 move upward and the diamond block 11 acts on the driving groove 10, and the ridge wall plates 402 on both sides of the whole body open to both sides, and the side walls of the ridge are initially and slowly compacted (to prevent the initially formed and uncompacted ridge from being unable to withstand the impact of the next step of the soil guide plate 401, the ridge wall plate 402, and the edge plate 403 being smashed down and causing the whole to collapse); when the cam 504 rotates to touch the left side wall of the through window 506: the cam 504 no longer acts Under the elastic restoring action of the spring 304, the soil guide plate 401, the ridge wall plate 402 and the edge plate 403 move downward; when the cam 504 rotates to touch the lower bottom wall of the contact through window 506, the soil guide plate 401, the ridge wall plate 402 and the edge plate 403 continue to move downward under the elastic restoring action of the spring 304, and begin to knock and compact the side wall of the ridge, and at this time, under the action of the diamond block 11 and the contact through window 506, the soil guide plate 401, the ridge wall plate 402 and the edge plate 403 also have the effect of compacting the side wall of the ridge and the top simultaneously. Example

[0045] like Figure 3 and Figure 4As shown, in this embodiment, based on the embodiment 2, in order to achieve a better compaction effect on the initially formed ridges, a pair of wing frames 13 are symmetrically fixed on the top of the mounting template 201, and a ridging wall panel 4 is movably installed on the two wing frames 13. By providing an additional ridging wall panel 4, it is possible to provide cooperative compaction on the opposite side during compaction, so as to avoid collapse of the opposite side during tamping and compaction. In order to adapt to different ridge widths, a pair of sliding sleeves 14 are fixed on the top of the ridging wall panel 4 on the wing frames 13. The wing frames 13 are configured with two wing rods 131 that slide through the sliding sleeves 14. A plurality of groups of limiting holes 132 that are arranged in a line are equidistantly along the length of the wing rods 131. The sliding sleeves 14 are threadedly connected with hand bolts 133 that can be inserted into the limiting holes 132. By moving the ridging wall panel 4 so that it slides on the wing rods 131 to a required length, the hand bolts 133 are rotated so that they are inserted into the limiting holes 132, thereby achieving the effect of adapting to different ridge widths. Example

[0046] like Figure 1 As shown, in order to allow the soil guide plate 401 and the ridge wall plate 402 to obtain sufficient soil when forming ridges, an auger blade 15 is additionally installed and fixed on the wheel axle of the walk-behind tractor 1. It should be noted that a slight improvement has been made to the wheel axle of the walk-behind tractor 1, mainly to increase the length of the wheel axle so that the auger blade 15 can be installed in a position. While the auger blade 15 rotates with the wheel axle, it can push the soil to both sides. On the one hand, it can reduce the resistance of the soil to the metal parts. On the other hand, the soil on the side is more conducive to the soil guide plate 401 and the ridge wall plate 402 to gather soil to form ridges.

[0047] The working process of the present invention is as follows: the user operates the walking tractor 1 to work, and the wheel shaft of the walking tractor 1 drives the auger blades 15 to rotate during the forward movement, and the auger blades 15 push the soil at the furrow position to both sides, and when the soil contacts the soil guide plate 401, the soil is gathered at the ridge position, and is gathered and shaped by the inclined surface of the ridge wall plate 402 that follows, so as to form a preliminary ridge;

[0048] At the same time, when the walking tractor 1 moves forward, the wheel 503 also rotates, and drives the wheel shaft to rotate, and the wheel shaft drives the cam 504 fixed thereon to rotate:

[0049] When the cam 504 rotates to touch the upper top wall of the through window 506, the soil guide plate 401, the ridge wall plate 402 and the edge plate 403 move upwards and the diamond block 11 acts on the driving groove 10, and the ridge wall plates 402 on both sides of the whole body open to both sides, and the side walls of the ridge are initially compacted;

[0050] When the cam 504 rotates to touch the left side wall of the through window 506, the cam 504 is no longer in effect, and the soil guide plate 401, the ridge wall plate 402, and the edge plate 403 move downward under the elastic force of the spring 304.

[0051] When the cam 504 rotates to touch the lower bottom wall of the contact through window 506, the soil guide plate 401, the ridge wall plate 402 and the edge plate 403 continue to move downward under the elastic restoring action of the spring 304, and begin to knock and compact the side wall of the ridge. At this time, under the action of the diamond block 11 and the contact through window 506, the soil guide plate 401, the ridge wall plate 402 and the edge plate 403 also have the effect of compacting the side wall of the ridge and the top simultaneously.

[0052] In this way, through repeated up and down compaction and tamping, the initially formed ridge is formed and will not be prone to collapse in the later stage.

[0053] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
