Description

Technical Field

[0001] The utility model relates to an agricultural tillage machine, in particular to a combined operation machine for weeding, loosening soil, spraying biogas slurry and burying in a greenhouse, that is, a greenhouse weeding, loosening soil, biogas slurry spraying combined tillage machine. Background Art

[0002] Some traditional seeders and soil loosening and topdressing machines can be used for granular fertilizer topdressing in greenhouses after being miniaturized, but they are not very suitable for liquid fertilizer fertilization. Liquid fertilizer includes: fertilizer solution, biogas slurry; the liquid part after the separation of feces and urine in livestock and poultry farms such as pig farms and cattle farms. Moreover, organic liquid fertilizer must be fully fermented before application. Poultry feces and liquids such as chicken manure must be fermented because of the high uric acid content, and direct application will cause "root burn". At present, liquid fertilizer fertilization generally involves spraying liquid fertilizer directly onto the surface of the field or leaves. For example, no-till biogas slurry spraying is carried out behind the fertilizer tanker without considering the burial link after spraying. This is easy to cause obvious volatilization problems for the greenhouse environment.

[0003] In view of this, it is necessary to develop a combined operation machine that can integrate and miniaturize spraying, burying and other operations at one time. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a biogas slurry spraying and cultivating machine which can be driven by a small tractor in a greenhouse and can complete biogas slurry spraying, burying, loosening soil and weeding in one operation.

[0018] The exemplary embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings. The exemplary embodiments described below and shown in the accompanying drawings are intended to teach the principles of the present utility model, so that those skilled in the art can implement and use the present utility model in several different environments and for several different applications. Therefore, the scope of protection of the present utility model is defined by the attached claims, and the exemplary embodiments are not intended to be, and should not be considered to be, a restrictive description of the scope of protection of the present utility model. Moreover, for the convenience of description, the sizes of the various parts shown in the accompanying drawings are not necessarily drawn according to the actual proportional relationship, and the orientation description, such as the front, rear, lateral, and upper, lower, left, right, top, bottom, etc., corresponding to the longitudinal forward route of the main body, are all based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. Unless otherwise specifically stated, the order of the components and assembly steps described in the embodiments and the numerical values ​​do not limit the scope of the present utility model.

[0019] According to the utility model, a greenhouse weeding, soil loosening, biogas liquid spraying and cultivation machine is provided, which can be driven by a tractor 11 or other traction equipment to operate in a greenhouse. Figure 1 As shown, it includes: a frame 9 connected to a suspension in the form of a three-point suspension 10, on which a furrow opener 3, a biogas slurry spray pipe 4, a weeding and loosening plow 5, a biogas slurry pump 6, and a biogas slurry tank 7 are respectively arranged.

[0020] The three-point suspension 10 can be installed on the tractor 11, or can be arranged integrally with the frame 9. At this time, the frame 9 can be arranged as a full suspension or semi-suspension structure.

[0021] The frame 9 is a frame structure, and a plurality of furrow openers 3 (such as furrow plows) arranged in pairs are fixedly installed at a horizontal interval on the front side below the frame 9, and each pair of furrow openers 3 is used for furrowing the left and right sides of the same ridge of vegetable seedlings 1. A biogas liquid spray pipe 4 is attached to the back of the furrowing surface of each furrow opener 3 for fertilization.

[0022] like Figure 2 The pair of furrow openers 3 shown are each adjustably fixedly mounted in the spacing hole 13 or the long strip hole of the frame cross beam 12 via a bolt 20 and a slider 14, so that they are symmetrically arranged on the left and right sides of the seedling 1 in a manner that the spacing between them is adjustable, and the spacing between the furrow openers 3 can be adjusted to suit different ridge widths or ridge distances. Of course, the spacing adjustment method is not limited to this, and a screw nut structure, a gear rack, etc. can also be used.

[0023] The biogas liquid spray pipe 4 is passed upward into the biogas liquid tank 7, which is fixedly mounted on the upper part of the frame 9, and a biogas liquid pump 6 is arranged between the biogas liquid tank 7 and the biogas liquid spray pipe 4. In this way, the biogas liquid stored in the biogas liquid tank 7 can be transported to the biogas liquid spray pipe 4 opened behind the furrow opener 3 through the biogas liquid pump 6, so as to be sprayed in the furrow.

[0024] Preferably, the paired biogas slurry spray pipes 4 corresponding to the paired furrow openers 3 can be connected to the same biogas slurry pump 6, so that the number of biogas slurry pumps 6 can be reduced. In particular, when the reverse return operation overlaps with at least one ridge that has been operated in the previous stroke, the same biogas slurry pump 6 corresponding to the ridge can be simply turned off to avoid repeated operations. Of course, all biogas slurry spray pipes 4 can share the same biogas slurry pump 6 or at least one biogas slurry spray pipe 4 does not use the liquid pump 6. It can be set as needed, or it can be set so that the biogas slurry spray pipes 4 adjacent to each other in two adjacent pairs of biogas slurry spray pipes 4 are connected to the same biogas slurry pump 6. In this way, fertilization between a certain ridge can be conveniently controlled.

[0025] The weeding and loosening plow 5 can be a plowshare shovel, which is arranged behind the furrow opener 3. While weeding and loosening the soil, the furrow opened by the furrow opener 3 can also be covered with soil, so that the biogas slurry just sprayed can be covered with soil, which can effectively prevent volatilization.

[0026] A grass collecting wheel 15 for collecting weeds from the turned-up loose soil is provided in front of the weeding and loosening plough 5. The weed collecting wheel 15 is used to roll up the weeds by means of ribs provided along the periphery thereof, so as to reduce the chance of weeds being covered in the ditch.

[0027] The biogas slurry tank 7 is also provided with a filter so that the biogas slurry can be filtered after being drawn out from the biogas tank and before being added into the biogas slurry tank 7 .

[0028] like Figure 1 As shown in the operation scene in FIG, vegetable seedlings 1 and weeds 2 grow in the vegetable field 8. The vegetable seedlings 1 grow in ridges on the center line of the ridges, and the weeds 2 are scattered in the furrows. The tractor 11 can move forward along the center line of the ridge. Directly behind the tractor 11, a frame 9 is towed by a three-point suspension 10. On the frame 9, a row of furrow openers 3 are arranged in a vertical direction of the tractor 11 and on a plumb plane perpendicular to the vegetable field 8. The furrow openers 3 are arranged in pairs, and the furrow openers 3 are aligned with the vegetable ridges in pairs. Each pair of furrow openers 3 is symmetrically arranged on the left and right sides of the vegetable seedlings 1, and the biogas slurry spray pipes 4 attached to the back of the furrowing surface of the furrow openers 3 are symmetrically placed on both sides of each ridge of vegetable seedlings 1.

[0029] In this way, a furrow opener 3 in the form of a furrow plow, for example, can be used to open furrows on both sides of the seedling ridge close to the seedlings, and the sludge spraying pipe 4 attached to the rear side of the furrow opener 3 sprays the sludge into the furrow, and then the corresponding weeding and loosening plow 5 moves forward along the furrow to remove the weeds in the furrow and loosen the soil at the same time. The soil in the turned-up furrow is covered into the furrows opened by the furrow opener 3 on both sides of the seedlings and sprayed with sludge at the same time, covering the newly sprayed sludge, reducing the volatilization of the sludge, and making the fertilizer and medicinal effects of the sludge last longer.
