Description

Technical Field

[0001] The utility model relates to the technical field of pit digging equipment, and more specifically to a kind of anti-sputtering pit digging equipment for tree planting. Background Art

[0002] Portable diggers are also called portable diggers. They are special machines for quickly digging holes in mountainous, hilly and gully areas for afforestation and fertilization. Diggers free people from heavy physical labor and are widely used in afforestation, fruit trees, fences, and fertilizing fruit trees in autumn. They have strong power, beautiful appearance, comfortable operation, low labor intensity, are suitable for various terrains, have high efficiency, are easy to carry and work in the field.

[0003] However, the existing portable digging machines are close to the spiral blades when digging, which poses a safety risk and causes soil splashing, which can easily cause the soil to splash to a distant location in the tree pit and onto the human body, increasing the cleaning process after digging, increasing the workload of the user, and thus reducing the working efficiency of the digging machine.

[0004] The existing Chinese patent invention, with publication number CN107926215A, is entitled a pit digger with dustproof function, which discloses a bracket, a rotating motor, a rotating shaft, a retractable rod, a cylinder and a dust cover to solve the problem that when using a portable pit digger to dig a pit, soil may splash everywhere, causing dust to fly. However, when the pit digger in the prior art digs a pit, the pit digger will bring the excavated soil out along the rotating blades and evenly lay it on the circumferential edge of the tree pit. The staff will move the pit digger away from the tree pit, put the sapling into the tree pit, and fill the soil. Because the excavated soil is arranged circumferentially around the tree pit, when filling the soil, the staff needs to move along the circumference of the tree pit while filling the soil. Especially in mountainous, hilly and gully areas, the ground is uneven, which is not convenient for moving and filling soil around the tree pit, reducing the efficiency of sapling planting.

[0005] Therefore, how to provide a tree planting pit digging equipment that can not only keep the excavated soil on one side of the tree pit, facilitate filling, improve tree planting efficiency, but also prevent soil splashing is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0006] In view of this, in order to solve the problems of inconvenient soil filling and soil splashing when digging holes, the utility model provides an anti-splashing hole digging equipment for tree planting, which does not require a close distance to the blades, and can bring the excavated soil out with the rotating blades and discharge it on one side of the tree pit, avoiding soil splashing while also making it convenient to backfill the soil. There is no need for workers to move around the tree pit to fill the soil, thereby improving planting efficiency.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A splash-proof pit digging device for tree planting, comprising:

[0009] A longitudinal support frame, wherein a horizontal support plate is fixedly connected to one side of the bottom of the longitudinal support frame, and a mounting hole is formed through the horizontal support plate;

[0010] A longitudinal slide rail, the longitudinal slide rail is installed in the longitudinal support frame, a slider that moves longitudinally is slidably connected to the longitudinal slide rail, a driving handle is vertically installed on one side of the slider, a tension spring is fixed on the top of the driving handle, and the top of the tension spring is abutted and fixed to the bottom end of the top plate of the longitudinal support frame;

[0011] A mobile platform, wherein a through hole is formed on the mobile platform, the mobile platform is arranged horizontally and one side of the mobile platform is fixedly connected to the slider, and the mobile platform is located above the horizontal support plate;

[0012] A driving device, wherein the driving device is mounted on the mobile platform, and an output end of the driving device is arranged corresponding to the through hole;

[0013] An auger digging mechanism, the auger digging mechanism is located below the mobile platform, the top of the auger digging mechanism is an input end and is transmission-connected to the output end of the driving device through the through hole, and the bottom end is spaced apart from the horizontal support plate;

[0014] An isolation cylinder, the lower end of which is installed in the installation hole, the outer edge end of the horizontal cross section of the auger digging mechanism is slidably abutted against the inner wall of the isolation cylinder, and a plurality of soil outlets arranged longitudinally at intervals are opened on one side of the isolation cylinder.

[0015] Through the above technical scheme, it can be known that compared with the prior art, the utility model discloses a kind of anti-splashing digging equipment for tree planting, which is moved to the target position to prepare for digging holes and planting trees. Because the bottom end of the top plate of the longitudinal support frame is connected to the driving handle by a tension spring, the sliding block connected to the driving handle, the moving platform connected to the sliding block, the driving device and the auger digging mechanism can be at a predetermined height position due to the tension of the tension spring. The operator first starts the driving device so that the output end of the driving device drives the auger digging mechanism to rotate, and then pulls the driving handle downward to make the sliding block slide downward on the longitudinal slide rail, thereby making the moving platform connected to the sliding block and the driving device and the auger digging mechanism on the moving platform move downward at the same time, and the auger digging mechanism just fits into the isolation cylinder. The end is installed in the horizontal support plate, and the auger digging mechanism rotates in the isolation cylinder and moves longitudinally downward to dig a hole. At this time, the auger digging mechanism and the isolation cylinder are slidably abutted to form an auger conveying cylinder, which can convey the excavated soil longitudinally upward in the isolation cylinder. Because a plurality of soil outlets arranged longitudinally at intervals are provided on one side of the isolation cylinder, the auger digging mechanism can spray the transported soil from the soil outlet to the outside of the isolation cylinder. Because the soil outlet is only provided on one side of the isolation cylinder, the soil transported upward by the auger digging mechanism will be scattered on one side of the tree pit no matter which soil outlet it is sprayed from. After the tree pit is dug, the digging equipment is moved away for planting. Because the soil is only on one side of the tree pit, the operating personnel do not need to move when filling the soil, avoiding the inconvenience of moving around the tree pit for filling due to irregular terrain such as mountains, hills, and gully areas. Therefore, the digging equipment for tree planting is not only convenient for controlling the lifting and lowering of the auger digging mechanism to dig holes, but also has an isolation cylinder to isolate the soil to prevent soil splashing and avoid safety problems for operators when the auger rotates. At the same time, the soil is scattered only on one side of the tree pit, and there is no need for operators to move around the tree pit to fill the soil, thereby improving planting efficiency.

[0016] Furthermore, the auger digging mechanism includes an auger shaft and blades, the blades are spirally and fixedly mounted on the shaft, and the top end of the shaft is fixedly connected to the driving end of the driving device.

[0017] Furthermore, the auger shaft includes a connecting shaft, a main shaft and a connecting sleeve.

The cross-sections of the connecting clamping groove and the main shaft clamping groove are both L-shaped and can be adaptably clamped. The connecting sleeve is sleeved at the clamping position of the connecting clamping groove and the main shaft clamping groove.

[0018] The beneficial effect of adopting the above technical solution is: setting the auger shaft as a clamped connecting shaft and main shaft can facilitate the disassembly and assembly of the main shaft and the blades installed on the main shaft, and at the same time a connecting shaft sleeve is sleeved at the connection between the connecting shaft and the main shaft to make the connection more secure.

[0019] Furthermore, it also includes a cleaning mechanism, which includes a cleaning shaft and a scraper plate, one side of the scraper plate is fixedly mounted on a side wall of the cleaning shaft, and the other end face of the scraper plate is slidably abutted against the inner wall of the isolation cylinder, and a cleaning shaft clamping groove is provided on the top of the cleaning shaft, the cleaning shaft clamping groove and the main shaft clamping groove have the same shape and can be alternately adapted to be clamped with the connecting clamping groove, and the connecting shaft sleeve is sleeved at the clamping position of the cleaning shaft clamping groove and the connecting clamping groove.

[0020] The beneficial effect of adopting the above technical solution is that the top end of the cleaning shaft of the cleaning mechanism has a cleaning shaft clamping groove that is adapted to be clamped with the connecting shaft. When the isolation cylinder needs to be cleaned, the cleaning mechanism can be conveniently replaced with the auger digging mechanism, and the driving device can be turned on to drive it. At the same time, the slider is controlled to slide downward, so that the scraper plate cleans the residual soil on the inner wall of the isolation cylinder.

[0021] Furthermore, there are two longitudinal slide rails installed at intervals inside the longitudinal support frame, there are two sliders installed respectively and slidably on the two longitudinal slide rails, and the opposite sides of the two sliders are connected by a slider connecting rod.

[0022] The beneficial effect of adopting the above technical solution is: the sliders are connected by the slider connecting rod, so that the two sliders always maintain the same height on the longitudinal slide rail and slide synchronously, so as to ensure the normal longitudinal movement of the mobile platform connected by the two sliders.

[0023] Furthermore, there are two driving handles which are respectively and vertically mounted on the side wall of the two sliding blocks opposite to the side wall of the movable platform, and the opposite sides of the two driving handles are connected by a handle connecting plate.

[0024] The beneficial effect of adopting the above technical solution is that the sliding block can be conveniently controlled to slide on the longitudinal sliding rail by driving the handle, thereby improving practicality.

[0025] Furthermore, the side of the longitudinal support frame facing the mobile platform is a working area, and the side opposite to the working area is a control area. The top plate extends horizontally along the direction of the control area, and the top end of the tension spring is fixed to the bottom end of the extended end of the top plate, and the bottom end is fixed to the top end of the slider connecting rod.

[0026] The beneficial effect of adopting the above technical solution is: by installing a tension spring between the handle connecting plate and the top plate, when controlling the descent of the slider, relying on the elastic force of the tension spring, part of the downward pulling force of the operator can be offset, so that the slider drives the mobile platform to slowly descend.

According to the actual situation during work, the fastening screws can be removed and the isolation cylinder 7 can be rotated to change the direction of the soil outlet 71 on the isolation cylinder 7 to improve applicability.

[0046] In one embodiment of the auger digging mechanism 6 of the utility model, the auger digging mechanism 6 comprises an auger shaft 61 and blades 62, the blades 62 are spirally fixedly mounted on the auger shaft 61, and the top of the auger shaft 61 is fixedly connected to the driving end of the driving device 5.

[0047] In the above embodiment, the auger shaft 61 includes a connecting shaft 611, a main shaft 612 and a connecting sleeve 613. The top of the connecting shaft 611 is fixedly connected to the output end of the driving device 5, and a connecting clamping groove 6111 is provided at the bottom.

The auger shaft 61 is configured as a clamped connecting shaft 611 and main shaft 612, which can facilitate the disassembly and assembly of the main shaft 612 and the blades 62 installed on the main shaft 612. At the same time, a connecting sleeve 613 is sleeved at the connection between the connecting shaft 611 and the main shaft 612 to make the connection more secure.

[0048] A screw hole is provided on the outer wall of the connecting sleeve 613 , and an adapter screw can be screwed in so that the screw is abutted and fixed against the wall surface of the connecting shaft 611 , thereby improving the installation stability of the connecting sleeve 613 .

[0049] In the above embodiment, a cleaning mechanism 8 is also included. The cleaning mechanism 8 includes a cleaning shaft 81 and a scraper plate 82. One side of the scraper plate 82 is fixedly mounted on a side wall of the cleaning shaft 81. The other end face of the scraper plate 82 is slidably abutted against the inner wall of the isolation cylinder 7. A cleaning shaft clamping groove 811 is provided on the top of the cleaning shaft 81. The cleaning shaft clamping groove 811 has the same shape as the main shaft clamping groove 6121 and can be alternately adapted to be clamped with the connecting clamping groove 6111. The connecting sleeve 613 is sleeved at the clamping position of the cleaning shaft clamping groove 811 and the connecting clamping groove 6111. The top of the cleaning shaft 81 of the cleaning mechanism 8 is provided with a cleaning shaft engaging groove 811 which is adapted to engage with the connecting shaft. When the isolation cylinder 7 needs to be cleaned, the cleaning mechanism 8 can conveniently replace the auger digging mechanism 6, and the driving device 5 is turned on to drive it. At the same time, the slider 31 is controlled to slide downward, so that the scraper plate 82 cleans the residual soil on the inner wall of the isolation cylinder 7.

[0050] The utility model is about an embodiment of the longitudinal slide rail 3, the longitudinal slide rail 3 is two and is installed at intervals inside the longitudinal support frame 1, the slider 31 is two and is slidably installed on the two longitudinal slide rails 3 respectively, and the opposite sides of the two sliders 31 are connected by a slider connecting rod 32. The sliders 31 are connected by the slider connecting rod 32, so that the two sliders 31 are always kept at the same height on the longitudinal slide rail 3 and slide synchronously, so as to ensure the normal longitudinal movement of the mobile platform 4 connected by the two sliders 31.

[0051] In the above embodiment, there are two driving handles 33, which are respectively and vertically mounted on the side wall of the two sliders 31 opposite to the side wall of the installation movable platform 4, and the opposite sides of the two driving handles 33 are connected by a handle connecting plate 331. The driving handles 33 can be used to conveniently control the slider 31 to slide on the longitudinal slide rail 3, thereby improving practicality.

[0052] In one embodiment of the utility model, the side of the longitudinal support frame 1 facing the mobile platform 4 is a working area, and the other side opposite to the working area is a control area. The top plate 11 extends horizontally in the direction of the control area. The top end of the tension spring 34 is fixed to the bottom end of the extension end of the top plate 11, and the bottom end is fixed to the top end of the handle connecting plate 331. By installing the tension spring 34 between the handle connecting plate 331 and the top plate 11, in the process of controlling the slider 31 to descend, the elastic force of the tension spring 34 can offset part of the downward pulling force of the operator, so that the slider 31 drives the mobile platform 4 to slowly descend, so as to avoid the auger digging mechanism 6 from being damaged by rapid contact with the ground, and prolong its service life. After completing the pit digging operation, the tension of the tension spring 34 on the handle connecting plate 331 makes it convenient for the operator to move the slider 31 to the original position. At the same time, the setting of the tension spring 34 makes the slider 31 and the mobile platform 4 connected to the slider 31 in a stable position in an idle state.

[0053] In one embodiment of the scale line 63 of the utility model, a scale line 63 for measuring the travel depth of the auger digging mechanism 6 is arranged on the wall surface of the longitudinal support frame 1 facing the control area, and a scale pointer 64 is installed on the side of the driving handle 33 close to the scale line 63. One side of the scale pointer 64 is parallel to the end surface where the scale line 63 is located, and the tip of the scale pointer 64 points to the scale line 63. By setting the scale line 63, when the operator controls the slider 31 to drive the mobile platform 4 to descend, the digging depth can be conveniently controlled through the indication of the scale pointer 64, thereby improving the practicality of the digging equipment.

[0054] Specifically, since the initial position of the auger digging mechanism 6 is above the isolation cylinder 7, in order to facilitate reading, it is only necessary to measure the height of the mobile platform 4 when the bottom end of the auger digging mechanism 6 contacts the ground, that is, the top of the scale line 63 is the initial end and is located below the push rod 92. The initial end of the scale line 63 is flush with the bottom end surface of the mobile platform 4. Then the mobile platform 4 is controlled to move downward to start reading and control the digging depth. The operation is convenient and more practical.

[0055] In one embodiment of the walking mechanism 9 in the present invention, the walking mechanism 9 includes a walking wheel 91 and two push rods 92. The walking wheel 91 is multiple and installed at intervals on the bottom end of the end surface of the longitudinal support frame 1 facing the control area. The two push rods 92 are respectively installed vertically on the end surface of the longitudinal support frame 1 located in the control area. The installation heights of the two push rods 92 are the same and located above the top of the scale line 63. By setting the walking mechanism 9, it is convenient to move the pit digging equipment manually. The process is specifically that the operator holds the push rod 92 at the same time, steps on the bottom rod of the longitudinal support frame 1 to provide driving force, and presses the push rod 92 downward to tilt the equipment. At this time, the walking wheel 92 contacts the ground to complete the movement of the pit digging equipment.

[0056] In the above embodiment, the walking mechanism 9 further includes a traction ring 93, which is mounted on the top of the top plate 11 and can be connected to a tractor. The traction ring 93 is arranged on the top and connected to the rear of the tractor through a connecting rod or a connecting belt, so that the digging equipment can be towed to complete long-distance transportation.

[0057] In addition, two shovel buckles 10 are longitudinally arranged at intervals on a side baffle of the longitudinal support frame 1, and the shovel can be inserted upside down into the two shovel buckles 10, which is convenient for workers to take and use for filling soil.

[0058] The working principle of the anti-splashing pit digging equipment for tree planting of the utility model is as follows:

[0059] The excavation equipment is moved to the target position in preparation for digging holes and planting trees. Because the bottom end of the top plate of the longitudinal support frame is connected to the handle block of the driving handle through a tension spring, the tension of the tension spring makes the slider connected to the driving handle, and the moving platform connected to the slider, as well as the driving device and the auger excavation mechanism be at a predetermined height position. The operator first starts the driving device to make the output end of the driving device drive the auger excavation mechanism to rotate, and then pulls the driving handle downward to make the slider slide downward on the longitudinal slide rail, thereby making the moving platform connected to the slider and the driving device and the auger excavation mechanism on the mobile platform move downward at the same time, and the auger excavation mechanism fits into the isolation cylinder just right. Because the lower end of the isolation cylinder is installed in the horizontal support plate, the auger excavation mechanism rotates in the isolation cylinder and moves longitudinally at the same time. Move downward, when the bottom end surface of the mobile platform is flush with the initial end of the scale line, the bottom end of the auger digging mechanism contacts the ground, and then moves downward to start digging. At this time, the auger digging mechanism and the isolation cylinder are slidably abutted to form an auger conveying cylinder, which can convey the excavated soil longitudinally upward in the isolation cylinder. Because a plurality of soil outlets arranged longitudinally at intervals are provided on one side of the isolation cylinder, the auger digging mechanism can spray the transported soil from the soil outlet to the outside of the isolation cylinder. Because the soil outlet is only provided on one side of the isolation cylinder, the soil transported upward by the auger digging mechanism will be scattered on one side of the tree pit no matter from which soil outlet it is sprayed, so that the operating personnel do not need to move when filling the soil, avoiding the inconvenience of moving around the tree pit for filling due to irregular terrain such as mountains, hills, and gully areas.

[0060] After the digging work is completed, the mobile platform is restored to its initial state, and the equipment is tilted by pushing the push rod downward, so that the walking wheels are in contact with the ground, making the equipment in the shape of a cart, which is convenient for short-distance movement in the field and moved to the next target position to dig a pit. After frequent and repeated digging, there will be residual soil in the blades and isolation cylinder of the auger digging mechanism. At this time, the screws on the connecting sleeve can be removed, and the connecting sleeve can be dragged upward to remove the main shaft with the blades, clean the blades, replace the cleaning mechanism, turn on the drive device, and pull the drive handle downward to make the bottom end surface of the mobile platform flush with the initial end of the scale line and then stop, just completing the cleaning of the inner wall of the isolation cylinder.

[0061] After all the digging operations are completed and the cleaning work is also completed, the rear end of the tractor can be connected to the traction ring through a connecting rod or a connecting belt to realize the long-distance transportation of the digging equipment.

[0062] Therefore, the pit digging equipment for tree planting can not only avoid splashing of excavated soil, but also make the soil accumulate on one side of the tree pit, which is convenient for backfilling. At the same time, it can keep workers away from the auger blades to avoid injuries, and it can also facilitate the cleaning of the auger blades and the inner wall of the isolation cylinder, which is convenient for the movement and long-distance transportation of the pit digging equipment.
